7 Tricks To Be Professional At Binary Options Trading

Everything You Always Wanted To Know About Swaps* (*But Were Afraid To Ask)

Hello, dummies
It's your old pal, Fuzzy.
As I'm sure you've all noticed, a lot of the stuff that gets posted here is - to put it delicately - fucking ridiculous. More backwards-ass shit gets posted to wallstreetbets than you'd see on a Westboro Baptist community message board. I mean, I had a look at the daily thread yesterday and..... yeesh. I know, I know. We all make like the divine Laura Dern circa 1992 on the daily and stick our hands deep into this steaming heap of shit to find the nuggets of valuable and/or hilarious information within (thanks for reading, BTW). I agree. I love it just the way it is too. That's what makes WSB great.
What I'm getting at is that a lot of the stuff that gets posted here - notwithstanding it being funny or interesting - is just... wrong. Like, fucking your cousin wrong. And to be clear, I mean the fucking your *first* cousin kinda wrong, before my Southerners in the back get all het up (simmer down, Billy Ray - I know Mabel's twice removed on your grand-sister's side). Truly, I try to let it slide. I do my bit to try and put you on the right path. Most of the time, I sleep easy no matter how badly I've seen someone explain what a bank liquidity crisis is. But out of all of those tens of thousands of misguided, autistic attempts at understanding the world of high finance, one thing gets so consistently - so *emphatically* - fucked up and misunderstood by you retards that last night I felt obligated at the end of a long work day to pull together this edition of Finance with Fuzzy just for you. It's so serious I'm not even going to make a u/pokimane gag. Have you guessed what it is yet? Here's a clue. It's in the title of the post.
That's right, friends. Today in the neighborhood we're going to talk all about hedging in financial markets - spots, swaps, collars, forwards, CDS, synthetic CDOs, all that fun shit. Don't worry; I'm going to explain what all the scary words mean and how they impact your OTM RH positions along the way.
We're going to break it down like this. (1) "What's a hedge, Fuzzy?" (2) Common Hedging Strategies and (3) All About ISDAs and Credit Default Swaps.
Before we begin. For the nerds and JV traders in the back (and anyone else who needs to hear this up front) - I am simplifying these descriptions for the purposes of this post. I am also obviously not going to try and cover every exotic form of hedge under the sun or give a detailed summation of what caused the financial crisis. If you are interested in something specific ask a question, but don't try and impress me with your Investopedia skills or technical points I didn't cover; I will just be forced to flex my years of IRL experience on you in the comments and you'll look like a big dummy.
TL;DR? Fuck you. There is no TL;DR. You've come this far already. What's a few more paragraphs? Put down the Cheetos and try to concentrate for the next 5-7 minutes. You'll learn something, and I promise I'll be gentle.
Ready? Let's get started.
1. The Tao of Risk: Hedging as a Way of Life
The simplest way to characterize what a hedge 'is' is to imagine every action having a binary outcome. One is bad, one is good. Red lines, green lines; uppie, downie. With me so far? Good. A 'hedge' is simply the employment of a strategy to mitigate the effect of your action having the wrong binary outcome. You wanted X, but you got Z! Frowny face. A hedge strategy introduces a third outcome. If you hedged against the possibility of Z happening, then you can wind up with Y instead. Not as good as X, but not as bad as Z. The technical definition I like to give my idiot juniors is as follows:
Utilization of a defensive strategy to mitigate risk, at a fraction of the cost to capital of the risk itself.
Congratulations. You just finished Hedging 101. "But Fuzzy, that's easy! I just sold a naked call against my 95% OTM put! I'm adequately hedged!". Spoiler alert: you're not (although good work on executing a collar, which I describe below). What I'm talking about here is what would be referred to as a 'perfect hedge'; a binary outcome where downside is totally mitigated by a risk management strategy. That's not how it works IRL. Pay attention; this is the tricky part.
You can't take a single position and conclude that you're adequately hedged because risks are fluid, not static. So you need to constantly adjust your position in order to maximize the value of the hedge and insure your position. You also need to consider exposure to more than one category of risk. There are micro (specific exposure) risks, and macro (trend exposure) risks, and both need to factor into the hedge calculus.
That's why, in the real world, the value of hedging depends entirely on the design of the hedging strategy itself. Here, when we say "value" of the hedge, we're not talking about cash money - we're talking about the intrinsic value of the hedge relative to the the risk profile of your underlying exposure. To achieve this, people hedge dynamically. In wallstreetbets terms, this means that as the value of your position changes, you need to change your hedges too. The idea is to efficiently and continuously distribute and rebalance risk across different states and periods, taking value from states in which the marginal cost of the hedge is low and putting it back into states where marginal cost of the hedge is high, until the shadow value of your underlying exposure is equalized across your positions. The punchline, I guess, is that one static position is a hedge in the same way that the finger paintings you make for your wife's boyfriend are art - it's technically correct, but you're only playing yourself by believing it.
Anyway. Obviously doing this as a small potatoes trader is hard but it's worth taking into account. Enough basic shit. So how does this work in markets?
2. A Hedging Taxonomy
The best place to start here is a practical question. What does a business need to hedge against? Think about the specific risk that an individual business faces. These are legion, so I'm just going to list a few of the key ones that apply to most corporates. (1) You have commodity risk for the shit you buy or the shit you use. (2) You have currency risk for the money you borrow. (3) You have rate risk on the debt you carry. (4) You have offtake risk for the shit you sell. Complicated, right? To help address the many and varied ways that shit can go wrong in a sophisticated market, smart operators like yours truly have devised a whole bundle of different instruments which can help you manage the risk. I might write about some of the more complicated ones in a later post if people are interested (CDO/CLOs, strip/stack hedges and bond swaps with option toggles come to mind) but let's stick to the basics for now.
(i) Swaps
A swap is one of the most common forms of hedge instrument, and they're used by pretty much everyone that can afford them. The language is complicated but the concept isn't, so pay attention and you'll be fine. This is the most important part of this section so it'll be the longest one.
Swaps are derivative contracts with two counterparties (before you ask, you can't trade 'em on an exchange - they're OTC instruments only). They're used to exchange one cash flow for another cash flow of equal expected value; doing this allows you to take speculative positions on certain financial prices or to alter the cash flows of existing assets or liabilities within a business. "Wait, Fuzz; slow down! What do you mean sets of cash flows?". Fear not, little autist. Ol' Fuzz has you covered.
The cash flows I'm talking about are referred to in swap-land as 'legs'. One leg is fixed - a set payment that's the same every time it gets paid - and the other is variable - it fluctuates (typically indexed off the price of the underlying risk that you are speculating on / protecting against). You set it up at the start so that they're notionally equal and the two legs net off; so at open, the swap is a zero NPV instrument. Here's where the fun starts. If the price that you based the variable leg of the swap on changes, the value of the swap will shift; the party on the wrong side of the move ponies up via the variable payment. It's a zero sum game.
I'll give you an example using the most vanilla swap around; an interest rate trade. Here's how it works. You borrow money from a bank, and they charge you a rate of interest. You lock the rate up front, because you're smart like that. But then - quelle surprise! - the rate gets better after you borrow. Now you're bagholding to the tune of, I don't know, 5 bps. Doesn't sound like much but on a billion dollar loan that's a lot of money (a classic example of the kind of 'small, deep hole' that's terrible for profits). Now, if you had a swap contract on the rate before you entered the trade, you're set; if the rate goes down, you get a payment under the swap. If it goes up, whatever payment you're making to the bank is netted off by the fact that you're borrowing at a sub-market rate. Win-win! Or, at least, Lose Less / Lose Less. That's the name of the game in hedging.
There are many different kinds of swaps, some of which are pretty exotic; but they're all different variations on the same theme. If your business has exposure to something which fluctuates in price, you trade swaps to hedge against the fluctuation. The valuation of swaps is also super interesting but I guarantee you that 99% of you won't understand it so I'm not going to try and explain it here although I encourage you to google it if you're interested.
Because they're OTC, none of them are filed publicly. Someeeeeetimes you see an ISDA (dsicussed below) but the confirms themselves (the individual swaps) are not filed. You can usually read about the hedging strategy in a 10-K, though. For what it's worth, most modern credit agreements ban speculative hedging. Top tip: This is occasionally something worth checking in credit agreements when you invest in businesses that are debt issuers - being able to do this increases the risk profile significantly and is particularly important in times of economic volatility (ctrl+f "non-speculative" in the credit agreement to be sure).
(ii) Forwards
A forward is a contract made today for the future delivery of an asset at a pre-agreed price. That's it. "But Fuzzy! That sounds just like a futures contract!". I know. Confusing, right? Just like a futures trade, forwards are generally used in commodity or forex land to protect against price fluctuations. The differences between forwards and futures are small but significant. I'm not going to go into super boring detail because I don't think many of you are commodities traders but it is still an important thing to understand even if you're just an RH jockey, so stick with me.
Just like swaps, forwards are OTC contracts - they're not publicly traded. This is distinct from futures, which are traded on exchanges (see The Ballad Of Big Dick Vick for some more color on this). In a forward, no money changes hands until the maturity date of the contract when delivery and receipt are carried out; price and quantity are locked in from day 1. As you now know having read about BDV, futures are marked to market daily, and normally people close them out with synthetic settlement using an inverse position. They're also liquid, and that makes them easier to unwind or close out in case shit goes sideways.
People use forwards when they absolutely have to get rid of the thing they made (or take delivery of the thing they need). If you're a miner, or a farmer, you use this shit to make sure that at the end of the production cycle, you can get rid of the shit you made (and you won't get fucked by someone taking cash settlement over delivery). If you're a buyer, you use them to guarantee that you'll get whatever the shit is that you'll need at a price agreed in advance. Because they're OTC, you can also exactly tailor them to the requirements of your particular circumstances.
These contracts are incredibly byzantine (and there are even crazier synthetic forwards you can see in money markets for the true degenerate fund managers). In my experience, only Texan oilfield magnates, commodities traders, and the weirdo forex crowd fuck with them. I (i) do not own a 10 gallon hat or a novelty size belt buckle (ii) do not wake up in the middle of the night freaking out about the price of pork fat and (iii) love greenbacks too much to care about other countries' monopoly money, so I don't fuck with them.
(iii) Collars
No, not the kind your wife is encouraging you to wear try out to 'spice things up' in the bedroom during quarantine. Collars are actually the hedging strategy most applicable to WSB. Collars deal with options! Hooray!
To execute a basic collar (also called a wrapper by tea-drinking Brits and people from the Antipodes), you buy an out of the money put while simultaneously writing a covered call on the same equity. The put protects your position against price drops and writing the call produces income that offsets the put premium. Doing this limits your tendies (you can only profit up to the strike price of the call) but also writes down your risk. If you screen large volume trades with a VOL/OI of more than 3 or 4x (and they're not bullshit biotech stocks), you can sometimes see these being constructed in real time as hedge funds protect themselves on their shorts.
(3) All About ISDAs, CDS and Synthetic CDOs
You may have heard about the mythical ISDA. Much like an indenture (discussed in my post on $F), it's a magic legal machine that lets you build swaps via trade confirms with a willing counterparty. They are very complicated legal documents and you need to be a true expert to fuck with them. Fortunately, I am, so I do. They're made of two parts; a Master (which is a form agreement that's always the same) and a Schedule (which amends the Master to include your specific terms). They are also the engine behind just about every major credit crunch of the last 10+ years.
First - a brief explainer. An ISDA is a not in and of itself a hedge - it's an umbrella contract that governs the terms of your swaps, which you use to construct your hedge position. You can trade commodities, forex, rates, whatever, all under the same ISDA.
Let me explain. Remember when we talked about swaps? Right. So. You can trade swaps on just about anything. In the late 90s and early 2000s, people had the smart idea of using other people's debt and or credit ratings as the variable leg of swap documentation. These are called credit default swaps. I was actually starting out at a bank during this time and, I gotta tell you, the only thing I can compare people's enthusiasm for this shit to was that moment in your early teens when you discover jerking off. Except, unlike your bathroom bound shame sessions to Mom's Sears catalogue, every single person you know felt that way too; and they're all doing it at once. It was a fiscal circlejerk of epic proportions, and the financial crisis was the inevitable bukkake finish. WSB autism is absolutely no comparison for the enthusiasm people had during this time for lighting each other's money on fire.
Here's how it works. You pick a company. Any company. Maybe even your own! And then you write a swap. In the swap, you define "Credit Event" with respect to that company's debt as the variable leg . And you write in... whatever you want. A ratings downgrade, default under the docs, failure to meet a leverage ratio or FCCR for a certain testing period... whatever. Now, this started out as a hedge position, just like we discussed above. The purest of intentions, of course. But then people realized - if bad shit happens, you make money. And banks... don't like calling in loans or forcing bankruptcies. Can you smell what the moral hazard is cooking?
Enter synthetic CDOs. CDOs are basically pools of asset backed securities that invest in debt (loans or bonds). They've been around for a minute but they got famous in the 2000s because a shitload of them containing subprime mortgage debt went belly up in 2008. This got a lot of publicity because a lot of sad looking rednecks got foreclosed on and were interviewed on CNBC. "OH!", the people cried. "Look at those big bad bankers buying up subprime loans! They caused this!". Wrong answer, America. The debt wasn't the problem. What a lot of people don't realize is that the real meat of the problem was not in regular way CDOs investing in bundles of shit mortgage debts in synthetic CDOs investing in CDS predicated on that debt. They're synthetic because they don't have a stake in the actual underlying debt; just the instruments riding on the coattails. The reason these are so popular (and remain so) is that smart structured attorneys and bankers like your faithful correspondent realized that an even more profitable and efficient way of building high yield products with limited downside was investing in instruments that profit from failure of debt and in instruments that rely on that debt and then hedging that exposure with other CDS instruments in paired trades, and on and on up the chain. The problem with doing this was that everyone wound up exposed to everybody else's books as a result, and when one went tits up, everybody did. Hence, recession, Basel III, etc. Thanks, Obama.
Heavy investment in CDS can also have a warping effect on the price of debt (something else that happened during the pre-financial crisis years and is starting to happen again now). This happens in three different ways. (1) Investors who previously were long on the debt hedge their position by selling CDS protection on the underlying, putting downward pressure on the debt price. (2) Investors who previously shorted the debt switch to buying CDS protection because the relatively illiquid debt (partic. when its a bond) trades at a discount below par compared to the CDS. The resulting reduction in short selling puts upward pressure on the bond price. (3) The delta in price and actual value of the debt tempts some investors to become NBTs (neg basis traders) who long the debt and purchase CDS protection. If traders can't take leverage, nothing happens to the price of the debt. If basis traders can take leverage (which is nearly always the case because they're holding a hedged position), they can push up or depress the debt price, goosing swap premiums etc. Anyway. Enough technical details.
I could keep going. This is a fascinating topic that is very poorly understood and explained, mainly because the people that caused it all still work on the street and use the same tactics today (it's also terribly taught at business schools because none of the teachers were actually around to see how this played out live). But it relates to the topic of today's lesson, so I thought I'd include it here.
Work depending, I'll be back next week with a covenant breakdown. Most upvoted ticker gets the post.
*EDIT 1\* In a total blowout, $PLAY won. So it's D&B time next week. Post will drop Monday at market open.

2 months back at trading (update) and some new questions

Hi all, I posted a thread back a few months ago when I started getting seriously back into trading after 20 years away. I thought I'd post an update with some notes on how I'm progressing. I like to type, so settle in. Maybe it'll help new traders who are exactly where I was 2 months ago, I dunno. Or maybe you'll wonder why you spent 3 minutes reading this. Risk/reward, yo.
I'm trading 5k on TastyWorks. I'm a newcomer to theta positive strategies and have done about two thirds of my overall trades in this style. However, most of my experience in trading in the past has been intraday timeframe oriented chart reading and momentum stuff. I learned almost everything "new" that I'm doing from TastyTrade, /options, /thetagang, and Option Alpha. I've enjoyed the material coming from esinvests YouTube channel quite a bit as well. The theta gang type strategies I've done have been almost entirely around binary event IV contraction (mostly earnings, but not always) and in most cases, capped to about $250 in risk per position.
The raw numbers:
Net PnL : +247
Commissions paid: -155
Fees: -42
Right away what jumps out is something that was indicated by realdeal43 and PapaCharlie9 in my previous thread. This is a tough, grindy way to trade a small account. It reminds me a little bit of when I was rising through the stakes in online poker, playing $2/4 limit holdem. Even if you're a profitable player in that game, beating the rake over the long term is very, very hard. Here, over 3 months of trading a conservative style with mostly defined risk strategies, my commissions are roughly equal to my net PnL. That is just insane, and I don't even think I've been overtrading.
55 trades total, win rate of 60%
22 neutral / other trades
Biggest wins:
Biggest losses:
This is pretty much where I expected to be while learning a bunch of new trading techniques. And no, this is not a large sample size so I have no idea whether or not I can be profitable trading this way (yet). I am heartened by the fact that I seem to be hitting my earnings trades and selling quick spikes in IV (like weed cures Corona day). I'm disheartened that I've went against my principles several times, holding trades for longer than I originally intended, or letting losses mount, believing that I could roll or manage my way out of trouble.
I still feel like I am going against my nature to some degree. My trading in years past was scalping oriented and simple. I was taught that a good trade was right almost immediately. If it went against me, I'd cut it immediately and look for a better entry. This is absolutely nothing like that. A good trade may take weeks to develop. It's been really hard for me to sit through the troughs and it's been even harder to watch an okay profit get taken out by a big swing in delta. Part of me wonders if I am cut out for this style at all and if I shouldn't just take my 5k and start trading micro futures. But that's a different post...
I'll share a couple of my meager learnings:


My new questions :

That's enough of this wall of text for now. If you made it this far, I salute you, because this shit was even longer than my last post.

Step-by-Step Guide for Adding a Stack, Expanding Control Lines, and Building an Assembler

After the positive response to my first tutorial on expanding the RAM, I thought I'd continue the fun by expanding the capabilities of Ben's 8-bit CPU even further. That said, you'll need to have done the work in the previous post to be able to do this. You can get a sense for what we'll do in this Imgur gallery.
In this tutorial, we'll balance software and hardware improvements to make this a pretty capable machine:

Parts List

To only update the hardware, you'll need:
If you want to update the toolchain, you'll need:
  1. Arduino Mega 2560 (Amazon) to create the programmer.
  2. Ribbon Jumper Cables (Amazon) to connect the Arduino to the breadboard.
  3. TL866 II Plus EEPROM Programmer (Amazon) to program the ROM.
Bonus Clock Improvement: One additional thing I did is replace the 74LS04 inverter in Ben's clock circuit with a 74LS14 inverting Schmitt trigger (datasheet, Jameco). The pinouts are identical! Just drop it in, wire the existing lines, and then run the clock output through it twice (since it's inverting) to get a squeaky clean clock signal. Useful if you want to go even faster with the CPU.

Step 1: Program with an Arduino and Assembler (Image 1, Image 2)

There's a certain delight in the physical programming of a computer with switches. This is how Bill Gates and Paul Allen famously programmed the Altair 8800 and started Microsoft. But at some point, the hardware becomes limited by how effectively you can input the software. After upgrading the RAM, I quickly felt constrained by how long it took to program everything.
You can continue to program the computer physically if you want and even after upgrading that option is still available, so this step is optional. There's probably many ways to approach the programming, but this way felt simple and in the spirit of the build. We'll use an Arduino Mega 2560, like the one in Ben's 6502 build, to program the RAM. We'll start with a homemade assembler then switch to something more robust.
Preparing the Physical Interface
The first thing to do is prepare the CPU to be programmed by the Arduino. We already did the hard work on this in the RAM upgrade tutorial by using the bus to write to the RAM and disconnecting the control ROM while in program mode. Now we just need to route the appropriate lines to a convenient spot on the board to plug the Arduino into.
  1. This is optional, but I rewired all the DIP switches to have ground on one side, rather than alternating sides like Ben's build. This just makes it easier to route wires.
  2. Wire the 8 address lines from the DIP switch, connecting the side opposite to ground (the one going to the chips) to a convenient point on the board. I put them on the far left, next to the address LEDs and above the write button circuit.
  3. Wire the 8 data lines from the DIP switch, connecting the side opposite to ground (the one going to the chips) directly below the address lines. Make sure they're separated by the gutter so they're not connected.
  4. Wire a line from the write button to your input area. You want to connect the side of the button that's not connected to ground (the one going to the chip).
So now you have one convenient spot with 8 address lines, 8 data lines, and a write line. If you want to get fancy, you can wire them into some kind of connector, but I found that ribbon jumper cables work nicely and keep things tidy.
The way we'll program the RAM is to enter program mode and set all the DIP switches to the high position (e.g., 11111111). Since the switches are upside-down, this means they'll all be disconnected and not driving to ground. The address and write lines will simply be floating and the data lines will be weakly pulled up by 1k resistors. Either way, the Arduino can now drive the signals going into the chips using its outputs.
Creating the Arduino Programmer
Now that we can interface with an Arduino, we need to write some software. If you follow Ben's 6502 video, you'll have all the knowledge you need to get this working. If you want some hints and code, see below (source code):
  1. Create arrays for your data and address lines. For example: const char ADDRESS_LINES[] = {39, 41, 43, 45, 47, 49, 51, 53};. Create your write line with #define RAM_WRITE 3.
  2. Create functions to enable and disable your address and data lines. You want to enable them before writing. Make sure to disable them afterward so that you can still manually program using DIP switches without disconnecting the Arduino. The code looks like this (just change INPUT to OUTPUT accordingly): for(int n = 0; n < 8; n += 1) { pinMode(ADDRESS_LINES[n], OUTPUT); }
  3. Create a function to write to an address. It'll look like void writeData(byte writeAddress, byte writeData) and basically use two loops, one for address and one for data, followed by toggling the write.
  4. Create a char array that contains your program and data. You can use #define to create opcodes like #define LDA 0x01.
  5. In your main function, loop through the program array and send it through writeData.
With this setup, you can now load multi-line programs in a fraction of a second! This can really come in handy with debugging by stress testing your CPU with software. Make sure to test your setup with existing programs you know run reliably. Now that you have your basic setup working, you can add 8 additional lines to read the bus and expand the program to let you read memory locations or even monitor the running of your CPU.
Making an Assembler
The above will serve us well but it's missing a key feature: labels. Labels are invaluable in assembly because they're so versatile. Jumps, subroutines, variables all use labels. The problem is that labels require parsing. Parsing is a fun project on the road to a compiler but not something I wanted to delve into right now--if you're interested, you can learn about Flex and Bison. Instead, I found a custom assembler that lets you define your CPU's instruction set and it'll do everything else for you. Let's get it setup:
  1. If you're on Windows, you can use the pre-built binaries. Otherwise, you'll need to install Rust and compile via cargo build.
  2. Create a file called 8bit.cpu and define your CPU instructions (source code). For example, LDA would be lda {address} -> 0x01 @ address[7:0]. What's cool is you can also now create the instruction's immediate variant instead of having to call it LDI: lda #{value} -> 0x05 @ value[7:0].
  3. You can now write assembly by adding #include "8bit.cpu" to the top of your code. There's a lot of neat features so make sure to read the documentation!
  4. Once you've written some assembly, you can generate the machine code using ./customasm yourprogram.s -f hexc -p. This prints out a char array just like our Arduino program used!
  5. Copy the char array into your Arduino program and send it to your CPU.
At this stage, you can start creating some pretty complex programs with ease. I would definitely play around with writing some larger programs. I actually found a bug in my hardware that was hidden for a while because my programs were never very complex!

Step 2: Expand the Control Lines (Image)

Before we can expand the CPU any further, we have to address the fact we're running out of control lines. An easy way to do this is to add a 3rd 28C16 ROM and be on your way. If you want something a little more involved but satisfying, read on.
Right now the control lines are one hot encoded. This means that if you have 4 lines, you can encode 4 states. But we know that a 4-bit binary number can encode 16 states. We'll use this principle via 74LS138 decoders, just like Ben used for the step counter.
Choosing the Control Line Combinations
Everything comes with trade-offs. In the case of combining control lines, it means the two control lines we choose to combine can never be activated at the same time. We can ensure this by encoding all the inputs together in the first 74LS138 and all the outputs together in a second 74LS138. We'll keep the remaining control lines directly connected.
Rewiring the Control Lines
If your build is anything like mine, the control lines are a bit of a mess. You'll need to be careful when rewiring to ensure it all comes back together correctly. Let's get to it:
  1. Place the two 74LS138 decoders on the far right side of the breadboard with the ROMs. Connect them to power and ground.
  2. You'll likely run out of inverters, so place a 74LS04 on the breadboard above your decoders. Connect it to power and ground.
  3. Carefully take your inputs (MI, RI, II, AI, BI, J) and wire them to the outputs of the left 74LS138. Do not wire anything to O0 because that's activated by 000 which won't work for us!
  4. Carefully take your outputs (RO, CO, AO, EO) and wire them to the outputs of the right 74LS138. Remember, do not wire anything to O0!
  5. Now, the 74LS138 outputs are active low, but the ROM outputs were active high. This means you need to swap the wiring on all your existing 74LS04 inverters for the LEDs and control lines to work. Make sure you track which control lines are supposed to be active high vs. active low!
  6. Wire E3 to power and E2 to ground. Connect the E1 on both 138s together, then connect it to the same line as OE on your ROMs. This will ensure that the outputs are disabled when you're in program mode. You can actually take off the 1k pull-up resistors from the previous tutorial at this stage, because the 138s actively drive the lines going to the 74LS04 inverters rather than floating like the ROMs.
At this point, you really need to ensure that the massive rewiring job was successful. Connect 3 jumper wires to A0-A2 and test all the combinations manually. Make sure the correct LED lights up and check with a multimeteoscilloscope that you're getting the right signal at each chip. Catching mistakes at this point will save you a lot of headaches! Now that everything is working, let's finish up:
  1. Connect A0-A2 of the left 74LS138 to the left ROM's A0-A2.
  2. Connect A0-A2 of the right 74LS138 to the right ROM's A0-A2.
  3. Distribute the rest of the control signals across the two ROMs.
Changing the ROM Code
This part is easy. We just need to update all of our #define with the new addresses and program the ROMs again. For clarity that we're not using one-hot encoding anymore, I recommend using hex instead of binary. So instead of #define MI 0b0000000100000000, we can use #define MI 0x0100, #define RI 0x0200, and so on.
Testing
Expanding the control lines required physically rewiring a lot of critical stuff, so small mistakes can creep up and make mysterious errors down the road. Write a program that activates each control line at least once and make sure it works properly! With your assembler and Arduino programmer, this should be trivial.
Bonus: Adding B Register Output
With the additional control lines, don't forget you can now add a BO signal easily which lets you fully use the B register.

Step 3: Add a Stack (Image 1, Image 2)

Adding a stack significantly expands the capability of the CPU. It enables subroutines, recursion, and handling interrupts (with some additional logic). We'll create our stack with an 8-bit stack pointer hard-coded from $0100 to $01FF, just like the 6502.
Wiring up the Stack Pointer
A stack pointer is conceptually similar to a program counter. It stores an address, you can read it and write to it, and it increments. The only difference between a stack pointer and a program counter is that the stack pointer must also decrement. To create our stack pointer, we'll use two 74LS193 4-bit up/down binary counters:
  1. Place a 74LS00 NAND gate, 74LS245 transceiver, and two 74LS193 counters in a row next to your output register. Wire up power and ground.
  2. Wire the the Carry output of the right 193 to the Count Up input of the left 193. Do the same for the Borrow output and Count Down input.
  3. Connect the Clear input between the two 193s and with an active high reset line. The B register has one you can use on its 74LS173s.
  4. Connect the Load input between the two 193s and to a new active low control line called SI on your 74LS138 decoder.
  5. Connect the QA-QD outputs of the lower counter to A8-A5 and the upper counter to A4-A1. Pay special attention because the output are in a weird order (BACD) and you want to make sure the lower A is connected to A8 and the upper A is connected to A4.
  6. Connect the A-D inputs of the lower counter to B8-B5 and the upper counter to B4-B1. Again, the inputs are in a weird order and on both sides of the chip so pay special attention.
  7. Connect the B1-B8 outputs of the 74LS245 transceiver to the bus.
  8. On the 74LS245 transceiver, connect DIR to power (high) and connect OE to a new active low control line called SO on your 74LS138 decoder.
  9. Add 8 LEDs and resistors to the lower part of the 74LS245 transceiver (A1-A8) so you can see what's going on with the stack pointer.
Enabling Increment & Decrement
We've now connected everything but the Count Up and Count Down inputs. The way the 74LS193 works is that if nothing is counting, both inputs are high. If you want to increment, you keep Count Down high and pulse Count Up. To decrement, you do the opposite. We'll use a 74LS00 NAND gate for this:
  1. Take the clock from the 74LS08 AND gate and make it an input into two different NAND gates on the 74LS00.
  2. Take the output from one NAND gate and wire it to the Count Up input on the lower 74LS193 counter. Take the other output and wire it to the Count Down input.
  3. Wire up a new active high control line called SP from your ROM to the NAND gate going into Count Up.
  4. Wire up a new active high control line called SM from your ROM to the NAND gate going into Count Down.
At this point, everything should be working. Your counter should be able to reset, input a value, output a value, and increment/decrement. But the issue is it'll be writing to $0000 to $00FF in the RAM! Let's fix that.
Accessing Higher Memory Addresses
We need the stack to be in a different place in memory than our regular program. The problem is, we only have an 8-bit bus, so how do we tell the RAM we want a higher address? We'll use a special control line to do this:
  1. Wire up an active high line called SA from the 28C16 ROM to A8 on the Cypress CY7C199 RAM.
  2. Add an LED and resistor so you can see when the stack is active.
That's it! Now, whenever we need the stack we can use a combination of the control line and stack pointer to access $0100 to $01FF.
Updating the Instruction Set
All that's left now is to create some instructions that utilize the stack. We'll need to settle some conventions before we begin:
If you want to add a little personal flair to your design, you can change the convention fairly easily. Let's implement push and pop (source code):
  1. Define all your new control lines, such as #define SI 0x0700 and #define SO 0x0005.
  2. Create two new instructions: PSH (1011) and POP (1100).
  3. PSH starts the same as any other for the first two steps: MI|CO and RO|II|CE. The next step is to put the contents of the stack pointer into the address register via MI|SO|SA. Recall that SA is the special control line that tells the memory to access the $01XX bank rather than $00XX.
  4. We then take the contents of AO and write it into the RAM. We can also increment the stack pointer at this stage. All of this is done via: AO|RI|SP|SA, followed by TR.
  5. POP is pretty similar. Start off with MI|CO and RO|II|CE. We then need to take a cycle and decrement the stack pointer with SM. Like with PSH, we then set the address register with MI|SO|SA.
  6. We now just need to output the RAM into our A register with RO|AI|SA and then end the instruction with TR.
  7. Updating the assembler is easy since neither instruction has operands. For example, push is just psh -> 0x0B.
And that's it! Write some programs that take advantage of your new 256 byte stack to make sure everything works as expected.

Step 4: Add Subroutine Instructions (Image)

The last step to complete our stack is to add subroutine instructions. This allows us to write complex programs and paves the way for things like interrupt handling.
Subroutines are like a blend of push/pop instructions and a jump. Basically, when you want to call a subroutine, you save your spot in the program by pushing the program counter onto the stack, then jumping to the subroutine's location in memory. When you're done with the subroutine, you simply pop the program counter value from the stack and jump back into it.
We'll follow 6502 conventions and only save and restore the program counter for subroutines. Other CPUs may choose to save more state, but it's generally left up to the programmer to ensure they're not wiping out states in their subroutines (e.g., push the A register at the start of your subroutine if you're messing with it and restore it before you leave).
Adding an Extra Opcode Line
I've started running low on opcodes at this point. Luckily, we still have two free address lines we can use. To enable 5-bit opcodes, simply wire up the 4Q output of your upper 74LS173 register to A7 of your 28C16 ROM (this assumes your opcodes are at A3-A6).
Updating the ROM Writer
At this point, you simply need to update the Arduino writer to support 32 instructions vs. the current 16. So, for example, UCODE_TEMPLATE[16][8] becomes UCODE_TEMPLATE[32][8] and you fill in the 16 new array elements with nop. The problem is that the Arduino only has so much memory and with the way Ben's code is written to support conditional jumps, it starts to get tight.
I bet the code can be re-written to handle this, but I had a TL866II Plus EEPROM programmer handy from the 6502 build and I felt it would be easier to start using that instead. Converting to a regular C program is really simple (source code):
  1. Copy all the #define, global const arrays (don't forget to expand them from 16 to 32), and void initUCode(). Add #include and #include to the top.
  2. In your traditional int main (void) C function, after initializing with initUCode(), make two arrays: char ucode_upper[2048] and char ucode_lower[2048].
  3. Take your existing loop code that loops through all addresses: for (int address = 0; address < 2048; address++).
  4. Modify instruction to be 5-bit with int instruction = (address & 0b00011111000) >> 3;.
  5. When writing, just write to the arrays like so: ucode_lower[address] = ucode[flags][instruction][step]; and ucode_upper[address] = ucode[flags][instruction][step] >> 8;.
  6. Open a new file with FILE *f = fopen("rom_upper.hex", "wb");, write to it with fwrite(ucode_upper, sizeof(char), sizeof(ucode_upper), f); and close it with fclose(f);. Repeat this with the lower ROM too.
  7. Compile your code using gcc (you can use any C compiler), like so: gcc -Wall makerom.c -o makerom.
Running your program will spit out two binary files with the full contents of each ROM. Writing the file via the TL866II Plus requires minipro and the following command: minipro -p CAT28C16A -w rom_upper.hex.
Adding Subroutine Instructions
At this point, I cleaned up my instruction set layout a bit. I made psh and pop 1000 and 1001, respectively. I then created two new instructions: jsr and rts. These allow us to jump to a subroutine and returns from a subroutine. They're relatively simple:
  1. For jsr, the first three steps are the same as psh: MI|CO, RO|II|CE, MI|SO|SA.
  2. On the next step, instead of AO we use CO to save the program counter to the stack: CO|RI|SP|SA.
  3. We then essentially read the 2nd byte to do a jump and terminate: MI|CO, RO|J.
  4. For rts, the first four steps are the same as pop: MI|CO, RO|II|CE, SM, MI|SO|SA.
  5. On the next step, instead of AI we use J to load the program counter with the contents in stack: RO|J|SA.
  6. We're not done! If we just left this as-is, we'd jump to the 2nd byte of jsr which is not an opcode, but a memory address. All hell would break loose! We need to add a CE step to increment the program counter and then terminate.
Once you update the ROM, you should have fully functioning subroutines with 5-bit opcodes. One great way to test them is to create a recursive program to calculate something--just don't go too deep or you'll end up with a stack overflow!

Conclusion

And that's it! Another successful upgrade of your 8-bit CPU. You now have a very capable machine and toolchain. At this point I would have a bunch of fun with the software aspects. In terms of hardware, there's a number of ways to go from here:
  1. Interrupts. Interrupts are just special subroutines triggered by an external line. You can make one similar to how Ben did conditional jumps. The only added complexity is the need to load/save the flags register since an interrupt can happen at any time and you don't want to destroy the state. Given this would take more than 8 steps, you'd also need to add another line for the step counter (see below).
  2. ROM expansion. At this point, address lines on the ROM are getting tight which limits any expansion possibilities. With the new approach to ROM programming, it's trivial to switch out the 28C16 for the 28C256 that Ben uses in the 6502. These give you 4 additional address lines for flags/interrupts, opcodes, and steps.
  3. LCD output. At this point, adding a 16x2 character LCD like Ben uses in the 6502 is very possible.
  4. Segment/bank register. It's essentially a 2nd memory address register that lets you access 256-byte segments/banks of RAM using bank switching. This lets you take full advantage of the 32K of RAM in the Cypress chip.
  5. Fast increment instructions. Add these to registers by replacing 74LS173s with 74LS193s, allowing you to more quickly increment without going through the ALU. This is used to speed up loops and array operations.

A guide to Battlecast Brawler Hyper Roll for patch 10.13

A guide to Battlecast Brawler Hyper Roll for patch 10.13

https://preview.redd.it/6auss91plw651.jpg?width=1209&format=pjpg&auto=webp&s=eb1e07aee7f71aa96df8c52179dfa6d0bd8b2b64

This is a guide to a battlecast brawler hyper roll build I've been working on in patch 10.13. (Or HyperBeam HyperRoll as i like to call it)


Down below I've shown what the comp should look like at various stages of the game, as well as the general strategy and itemization.

Hyper roll builds have disappeared from the meta with the introduction of set 3.5, mostly to to the nerfing of key 1 cost units like Poppy and Xylah, the removal of the Void alliance, and level 4 rolling odds changing from 60% to 55% for 1 cost units.
However, I think with the massive buffs to Illaoi and the battlecast synergy and it's units, as well as the massive increase in odds for 3 cost units from 10% to 15% at level 4 make this build viable if you abuse those odds to find an early Cassiopeia, and get 4 battlecast online early after hyper rolling at stage 3-1. You're almost guaranteed to have her on round 3-2, often you will even find 2 copies or a 2 star Cassiopeia on your first hyper roll. I think by shifting the focus of hyper roll builds away from 3 starring a board of 1 and 2 cost units, and focusing more on abusing the 15% odds for 3 cost units, and focusing on 3 starring a few one cost units, and getting super early 2 star 3 costs who unlock important synergies, hyper rolling can be quite good again.
Anyways, here's the rundown of the comp:

The build focuses on building Illaoi and Cassiopeia as your carries. The compound effect of all the buffs to Illaoi and battlecast have made her tankiness and power increase exponentially, especially at 3 star. Combining the buffed heal from battlecast with the bonus HP she got this patch, 10% more armor and magic resist steal and the massive 50% increase from 4 second to 6 second steal duration, allowing her to stack up much more at a single time makes her a way stronger unit at 3 star than she was in 10.12. Combining this with the right set of items easily rivals Poppy in the golden days of the Candyland build. As for Cassiopeia, despite getting a nerf to DPS, the amount of damage instances she does is very powerful with the battlecast synergy. With Blue Buff and Morellonomicon, you'll be dealing 2 instances of tick damage on your opponents entire team very early into the fight, triggering tons of blasts/heals. When played in this comp, she is a way stronger carry than she is in the Vanguard Mystic build, despite being nerfed. The 4 battlecast synergy has been buffed enough that it can crush early game and carry you through mid, until you find Urgot later, and the 6 battlecast alliance has been buffed enough to make this build viable in the late/top 4 portion of the game. Buffs to Nocturne and Kog'Maw aren't huge, but still relevant. This comp also makes great use of spatula. If you can get battlecast spat, you can run 6 battlecasts at level 6, without needing to to wait all the way to level 8 to find Urgot. The 480 damage blasts/heals at earlier stages of the game will pretty much ensure you steamroll.
In summary, the comp wants to have long fights with an unkillable Illaoi and Malphite 3 star in the front, buying time for Cassiopeia's damage over time, and your battlecast procs to do work, while the combination of Ionic Spark and Illaoi's resistance reductions massively increase your damage output as your tanks run endlessly into the opponents units and debuff them to oblivion.

Super Early Game (Stage 1-2)

In the super early game, you should econ as much as possible. Focus on making interest at all times, and only deviate from this if it means picking up an Illaoi, Cassiopeia, Malphite, or Nocturne. You want to hang onto as few units as possible that don't go into the level 5 comp shown below. Holding onto one Kog'maw is a good idea, but 2 starring him before you roll down your gold at 3-1 isn't worth it. It costs way too much in interest gold and you will always be able to 2 star him very early with your hyper rolls, and having him 2 star isn't the most important thing. What really matters is having him for an early 4 battlecast synergy. If you can sell Cog'Maw to make interest it's generally worth it, as you can always find another copy during your hyper roll. You want to streak for maximum econ without ever breaking your streak, which usually means loss streaking until the crug round. This also ensures you get first/early pick at the carousel. Getting the right items, specifically an early bramble for your Illaoi, is important for this comp, so it's normally the best approach. I wouldn't recommend committing to win streaking unless you're entering the first PVP rounds with 2 star units and some solid completed items, or if you lucked out and got Cassiopeia on stage 1. Ideally you want between 40-50 gold for stage 3-1, at which point you hyper roll to 0 and try to 3 star Illaoi Malphite and Nocturne, while 2 starring Kog'Maw, and finding Cassiopeia 1 or 2 star. Consider holding onto Blitz crank and Vi during your roll, until you find the 4 battlecasts so you can play a 4 brawler start as a backup plan if need be.

Sidenote: picking up as many 1 cost and 3 cost units as possible while you're rolling down your gold will slightly increase your chances of 3 starring units and hitting Cassiopeias by removing some units from the pool. This isn't huge but it can be the difference between hitting a 3 star unit a round or two earlier, which does matter.

Early Game (Level 4-5)

Level 5
You want to get Illaoi to 3 star as your top priority, while looking for Malphite and Nocturne 3 star along the way. Kog'Maw 3 star is nice but it isn't worth the bench space and gold and will ultimately slow you down too much. Getting him to 2 star early is all you need. The other goal is to find Cassiopeia 2 star early during the hyper rolls, but never roll specifically for her, as a 1 star Cassiopeia is all you need early on, and you should get her to 2 star extremely early naturally with your hyper rolls now giving you 15% chance for 3 cost units in the early game anyways. The only 3 star unit that is absolutely crucial to the comp is Illaoi. Malphite makes the comp much stronger if you can 3 star him, but the comp can function without him. 3 star Nocturne is much like Zoe in Candyland; a nice bonus if you find him, and quite useful with his 4 second stun, but you don't need him 3 star. It's always worth the econ and bench to hang onto him though. Since this is a hyper roll build, you never spend money on exp until you are fully ready to go to level 6, where your odds for finding 1 cost units decrease drastically. Once you find Illaoi 3 star, you should go to level 6 if you aren't anywhere near finding Malphite and nocturne 3, but if you have 5 or more copies of either of them, and if the units aren't being heavily contested, it's worth staying at level 5 longer and rolling down again for 3 star on all your 1 costs first. Be patient with your gold, and try to econ up to 30-50 gold before rolling down each time, instead of rolling all your gold as you get it, unless you are dying and have no other option. You usually want to run the 5 units shown above, however if you failed to find 4 battlecast, you can run 4 Brawler instead, although this isn't as good. The other main thing to consider is running Zed instead of Malphite. Zed can be worth it if you ended up with a 3 star Nocturne, or if you somehow didn't find 2 star Malphite on your first hyper roll, which is incredibly unlikely. Otherwise the 2 Brawler front line with 4 battlecast is your best option.

Mid Game (Level 6-7)

Level 6
level 7
At this point, hopefully Illaoi and as many other 1 costs as possible are 3 starred, or 1-2 copies away from being 3 starred, and you have 2 star Cassiopeia. The best option at level 6 is to add a Mystic to further increase your units durability. Soraka is great, and her healing has great synergy with the innate tankiness of your units. Karma is also great to link to your Cassiopeia. If you can't find a mystic the option of throwing in a 2 star Zed or a Fizz is also okay. Running Infiltrator in the place of Mystic can actually be better up until late game if Nocturne is 3 starred. At this point in the game, you don't want to be rolling any more. Just econ up and pick up more brawlers, and finish 2 starring everything you can, and finishing 3 star units unless it becomes unrealistic to keep looking for them. At level 7, you want to add in two brawlers and take out the mystic, for 4 brawler 4 battlecast. Adding Vi and Gnar provides much more valuable front line to buy time and drag out the fight for your Cassiopeia and battlecast procs to do work, as well as providing you with lots of CC. If the game is going well, i prefer to econ up to 50 on level 6 and slowly pump gold into exp, while remaining at 50 gold, then pump all my gold into levels to jump strait to level 8 right after, but if you are being pressured it's fine to go to 7 sooner if you're taking too much damage.

Late Game (Level 8-9)

Level 8
Level 8 alt
Level 9
At level 8, add your Mystic back in (Soraka being the best). You don't have much to do here as far as your build, aside from trying to find Urgot and Viktor, if you don't already have him, to go to 6 battlecast. Once you find Urgot, either replace Cog'Maw with him (or Nocturne if you never 3 starred him) or take out 2 of your brawlers and go for 6 battlecast, 2 brawler, 2 mystic. If the game goes to Level 9, you can simply play 4 brawler 6 battlecast. If you're facing heavy magic damage lineups that don't require you to strengthen your front line as much (such as Gangplank/Riven and 6 sorcerers) you can consider 4 mystics instead of 4 brawlers. This is especially effective if you have dragon scale on Illaoi, and practically allows her to 1v9 against those kind of comps.

Spatula Variation

Level 6
Level 9
If you get a spatula, you can make battlecast spat and put it onto your Malphite. Malphite carries Ionic spark in this comp, so giving him the ability to output some magic damage is nice while hes tanking for you, but more importantly he has tons of hp to work with so he will survive on the front line for much longer with battlecast heals and keep that ionic spark aura up for longer.
With battlecast spat, you can add Viktor in at level 6 for the 6 battlecast synergy. The DPS increase to 480 for each battlecast proc at this early in the game is brutal, and also makes Illaoi unkillable with the increase heal. You can play 4 brawler 6 battlecast at level 8 now as well, and at level 9 you can play a mystic on top of the normal comp, while dropping one of your less useful battlecasts.

Items

Carousel Priority is Spatula > Chain Vest > Cloak > TeaRod > Belt/Gloves

It's essential that you prioritize getting Bramble first, Blue Buff second, then two additional tank items for Illaoi and Morellonomicon as a third priority, and lastly Ionic Spark or Rapid Firecannon are luxury items (they help you win more if you're ahead, but don't stabilize you if you're behind).

Basically, Bramble vest is the most important item in the comp, with Blue Buff being a close second. They are the only irreplaceable items. Bramble plays a crucial role in carrying you through all stages of the game. It's value on tanky units, especially at 3 star, is too great to ever pass up. It will do a ton of AOE damage, and it creates quite a lot of damage instances throughout the fight to fuel battlecast.

Ideally, Illaoi wants Bramble, Dragon Scale and Quicksilver. I believe these items best leverage her stolen resistances from her spell and increase her survivability.
The armor from vest, plus the negating of crits, coupled with 20% evasion from quicksilver, makes her very durable against physical damage.
The magic resist provided by Dragon scale and Quicksilver bring her magic resistance extremely high, and she ends up taking almost no damage when incoming magic damage is reduced by 50% by scale before even considering her resistances.
The immunity to crowd control from Quicksilver is very important on her as well, as it allows her to cast without interruption, and she can't be stunned before she has a chance to steal resistances. Stacking up a few casts in the first 10 seconds of the fight is enough to make sure she is always working with added armor and magic resist.
Getting these 3 items isn't imperative though, as long as you have bramble you can replace one of the other slots. Warmog's works fine in giving her more raw HP to leverage her mass stolen armor and magic res, and gives her more HP to stay alive and heal back up with battlecast procs. Titan's resolve is also an acceptable replacement as she is one of the units who can actually get it to 50 stacks and then stay alive and heal back up for a long time thereafter to make good use of the item to its full potential.

Cassiopeia wants Blue Buff and Morellonomicon. With this combination of items, she can dish out tons of damage over time as long as she has a tanky front line to buy time for the damage to do its work, as we've seen in builds like Vanguard Mystic and Mystic Protectors. Given two sources of tick damage on every unit that she casts on, not only does she melt entire teams, she goes rapid-fire with the battlecast procs, even managing to stay alive through rapid healing if she gets jumped on the back line.

The last item is Ionic Spark. This is best on Malphite 3 star, but can be on any Brawler. I don't recommend putting it on Illaoi because it offers less defensively and we just want to make her as tanky as possible with her 3 slots. Combining the magic resistance debuff aura and Illaoi stealing 60% resistances every cast from whoever she hits, your team will be able to easily melt enemies.

Almost all item components have good use in this comp, but BF Sword is quite a dead item. The best you can do is make a Zeke's Herald or GA with it.

Other notable items if you happen to get them:

Rapid Firecannon - Great on Cassiopeia, and allows you to position her as safe and far away as possible. Any Bows you pick up should go towards building this item. It didn't make the cut for the item build, but it would be the next best thing that isn't on the core 6 item list. Don't prioritize bows on the carousel over anything else for this item, but it's nice if you end up with one.

Protector Spat - Spatula should be built into battlecast spat, but if that ends up being impossible, or you pick up the full item on a later carousel, it can be great for Cassiopeia to perma-shield once you activate protector synergy with Urgot. Jarvin and Karma can be played until you find Urgot, to get protector and dark star.

Thief's Gloves - If you end up with extra Sparring Gloves you can just combine them onto Nocturne or victor to get some value out of them.

Frozen Heart - If you have spare chain vest and tear drops, this is a nice item to have on either a brawler, or on Nocturne.

ZZ'Rot Portal/Redemption - If you end up with these, they're nice on Nocturne, as he will jump to the back line, cause havoc, then give you benefits for dying.

Positioning

Depending on what brawlers you're using, there are two general approaches to positioning Cassiopeia. If you have all your brawlers up front, it's best to have her to the second row against one of the edges, with a brawler directly in front of her. If you're running Blitzcrank, you can put him in the corner with Cassiopeia next to him. This will give her a target to attack in between casting her spell. Since she only needs to hit once to gain full mana with blue buff, she should be able to distribute her poison to most of the enemy team from the safety of the back row before the pulled unit dies, forcing her to move up closer.

Malphite (or whoever ends up with Ionic Spark) should be towards the center to maximize the aura's effect. Illaoi should also be centered. Her and Malphite are the tankiest units assuming they're three starred, and it's also best to have her near the Ionic spark to ensure she stacks magic resistance reduction from Tentacle Smash and ionic spark onto the same units, helping your team burst down targets better.

Nocturne can typically kill off a target during his 4 second stun duration, so having him jump onto a key spell caster such as Lulu/Xeraph or a carry is important. In the top 4 and above, his positioning becomes increasingly more important as you can target specific players more easily.

Cow'Maw isn't the most impactful unit, so he should be positioned in such a way that he will tankenemy Blitzcranks.

In general, I prefer to play towards one side in the early game, to better help your units focus fire, and cause battlecast to target the same unit. later on, I typically prefer to spread out more.

Pros and Cons

Pros:

- Counters Vanguards and Mystics. Cassiopeia with Morellonomicon melts them, and Illaoi's spell turns their own strength against them, making her ridiculously tanky and stripping them of their alliance bonuses.

- Counters Protectors due to Cassiopeia 50% shield reduction.

- Not Super contested in general. Not many players are 3 starring these units, and with hyper rolls you can get your hands on the highly contested Cassiopeia before anyone has a chance to empty them out of the pool.

- Good in Trade Sector, Neekoverse, Star Cluster, Superdense Galaxies.

- Easy Top 4 if you get some 3 stars at a reasonable time, or hit your items on Cassiopeia and Illaoi

Cons:

- Easy Bottom 4 if you get unlucky with your hyper rolls

- Can struggle against Blasters with the 80% true damage from Giant Slayers against your High HP units, and heal reduction from Red Buff. If more than two players are going blaster brawler, you shouldn't go for this comp, as your units will be contested as well and 3 starring the important ones could become impossible.

- Can be weak against sorcerers. Burst damage comes in less, more intense damage instances, and doesn't let you proc enough battlecast heals. Their units often don't have much resistance to steal making Illaoi less effective and more vulnerable, as well as losing value on HP% burn from Cassiopeia since their units are fairly low hp.

- Bad in Binary Star and Galactic Armory. Risky in Littler Little Legends Galaxy. If you snowball early you can crush the game easily, but if you take a bit too long hitting your power spikes, you'll be in a rough spot.

That's it for the guide, thanks for reading! I hope you give this comp a try and have fun!

Figured since no one else started one, and since I'm so active here, I'd do it. Magyst is looking for bugs the team can look into. This is a work in progress list, so feel free to post about your bugs (preferably with video/picture proof where necessary) and I will add it to the list. Issues already listed on the Trello will not be included.
I'm listing issues in order of my personal perceived importance (based off of how frequent and how impactful the bug is), with cosmetic issues as lowest on the totem pole. I realize some of you may not agree, and that's ok. Also, just because I list one bug higher than another, it doesn't mean Epic will be able to squash it before something lower on the list.
Major Issues
Moderate Issues
Minor Issues
Cosmetic/Visual Issues
Possible Bugs/Unannounced Changes?
PS. More communication with the community please.

[Table] Asteroid Day AMA – We’re engineers and scientists working on a mission that could, one day, help save humankind from asteroid extinction. Ask us anything!

Source
There are several people answering: Paolo Martino is PM, Marco Micheli is MM, Heli Greus is HG, Detlef Koschny is DVK, and Aidan Cowley is AC.
Questions Answers
Can we really detect any asteroids in space with accuracy and do we have any real means of destroying it? Yes, we can detect new asteroids when they are still in space. Every night dozens of new asteroids are found, including a few that can come close to the Earth.
Regarding the second part of the question, the goal would be to deflect them more than destroy them, and it is technologically possible. The Hera/DART mission currently being developed by ESA and NASA will demonstrate exactly this capability.
MM
I always wanted to ask: what is worse for life on Earth - to be hit by a single coalesced asteroid chunk, or to be hit by a multiple smaller pieces of exploded asteroid, aka disrupted rubble pile scenario? DVK: This is difficult to answer. If the rubble is small (centimetres to meters) it is better to have lots of small ones – they’d create nice bright meteors. If the rubble pieces are tens of meters it doesn’t help.
Let’s say that hypothetically, an asteroid the size of Rhode Island is coming at us, it will be a direct hit - you’ve had the resources and funding you need, your plan is fully in place, everything you’ve wanted you got. The asteroid will hit in 10 years, what do you do? DVK: I had to look up how big Rhode Island is – a bit larger than the German Bundesland ‘Saarland’. Ok – this would correspond to an object about 60 km in diameter, right? That’s quite big – we would need a lot of rocket launches, this would be extremely difficult. I would pray. The good news is that we are quite convinced that we know all objects larger than just a few kilometers which come close to our planet. None of them is on a collision course, so we are safe.
the below is a reply to the above
Why are you quite convinced that you know all object of that size? And what is your approach in finding new celestial bodies? DVK: There was a scientific study done over a few years (published in Icarus 2018, search for Granvik) where they modelled how many objects there are out there. They compared this to the observations we have with the telescopic surveys. This gives us the expected numbers shown here on our infographic: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
There are additional studies to estimate the ‘completeness’ – and we think that we know everything above roughly a few km in size.
To find new objects, we use survey telescopes that scan the night sky every night. The two major ones are Catalina and Pan-STARRS, funded by NASA. ESA is developing the so-called Flyeye telescope to add to this effort https://www.esa.int/ESA_Multimedia/Images/2017/02/Flyeye_telescope.
the below is a reply to the above
Thanks for the answer, that's really interesting! It's also funny that the fist Flyeye deployed is in Sicily, at less than 100km from me, I really had no idea DVK: Indeed, that's cool. Maybe you can go and visit it one day.
the below is a reply to the original answer
What about Interstellar objects however, like Oumuamua? DVK: The two that we have seen - 'Oumuamua and comet Borisov - were much smaller than the Saarland (or Rhode Island ;-) - not sure about Borisov, but 'Oumuamua was a few hundred meters in size. So while they could indeed come as a complete surprise, they are so rare that I wouldn't worry.
Would the public be informed if an impending asteroid event were to happen? And, how would the extinction play out? Bunch of people crushed to death, knocked off our orbit, dust clouds forever? DVK: We do not keep things secret – all our info is at the web page http://neo.ssa.esa.int. The ‘risky’ objects are in the ‘risk page’. We also put info on really close approaches there. It would also be very difficult to keep things ‘under cover’ – there are many high-quality amateur astronomers out there that would notice.
In 2029 asteroid Apophis will fly really close to Earth, even closer than geostationary satellites. Can we use some of those satellites to observe the asteroid? Is it possible to launch very cheap cube sats to flyby Apophis in 2029? DVK: Yes an Apophis mission during the flyby in 2029 would be really nice. We even had a special session on that topic at the last Planetary Defense Conference in 2019, and indeed CubeSats were mentioned. This would be a nice university project – get me a close-up of the asteroid with the Earth in the background!
the below is a reply to the above
So you’re saying it was discussed and shelved? In the conference we just presented ideas. To make them happen needs funding - in the case of ESA the support of our member countries. But having something presented at a conference is the first step. One of the results of the conference was a statement to space agencies to consider embarking on such a mission. See here: https://www.cosmos.esa.int/documents/336356/336472/PDC_2019_Summary_Report_FINAL_FINAL.pdf/341b9451-0ce8-f338-5d68-714a0aada29b?t=1569333739470
Go to the section 'resolutions'. This is now a statement that scientists can use to present to their funding agencies, demonstrating that it's not just their own idea.
Thanks for doing this AMA! Did we know the Chelyabinsk meteor in 2013 (the one which had some great videos on social media) was coming? Ig not, how comes? Also, as a little side one, have there been any fatalities from impact events in the past 20 years? Unfortunately, the Chelyabinsk object was not seen in advance, because it came from the direction of the Sun where ground-based telescopes cannot look.
No known fatalities from impacts have happened in the past 20 years, although the Chelyabinsk event did cause many injuries, fortunately mostly minor.
MM
the below is a reply to the above
How often do impacts from that direction happen, compared to impacts from visible trajectories? In terms of fraction of the sky, the area that cannot be easily scanned from the ground is roughly a circle with a radius of 40°-50° around the current position of the Sun, corresponding to ~15% of the total sky. However, there is a slight enhancement of objects coming from that direction, therefore the fraction of objects that may be missed when heading towards us is a bit higher.
However, this applies only when detecting an asteroid in its "final plunge" towards the Earth. Larger asteroids can be spotted many orbits earlier, when they are farther away and visible in the night side of the sky. Their orbits can then be determined and their possible impacts predicted even years or decades in advance.
MM
There must be a trade-off when targeting asteroids as they get closer to Earth, is there a rule of thumb at what the best time is to reach them, in terms of launch time versus time to reach the asteroid and then distance from Earth? DVK: Take e.g. a ‘kinetic impactor’ mission, like what DART and Hera are testing. Since we only change the velocity of the asteroid slightly, we need to hit the object early enough so that the object has time to move away from it’s collision course. Finding out when it is possible to launch requires simulations done by our mission analysis team. They take the strength of the launcher into account, also the available fuel for course corrections, and other things. Normally each asteroid has its own best scenario.
Do you also look at protecting the moon from asteroids? Would an impact of a large enough scale potentially have major impacts on the earth? DVK: There are programmes that monitor the Moon and look for flashes from impacting small asteroids (or meteoroids) - https://neliota.astro.noa.g or the Spanish MIDAS project. We use the data to improve our knowledge about these objects. These programmes just look at what is happening now.
For now we would not do anything if we predicted a lunar impact. I guess this will change once we have a lunar base in place.
Why aren't there an international organisation comprised of countries focused on the asteroid defence? Imagine like the organisation with multi-billion $ budget and program of action on funding new telescopes, asteroid exploration mission, plans for detection of potentially dangerous NEA, protocols on action after the detection - all international, with heads of states discussing these problems? DVK: There are international entities in place, mandated by the UN: The International Asteroid Warning Network (http://www.iawn.net) and the Space Mission Planning Advisory Group (http://www.smpag.net). These groups advise the United Nations. That is exactly where we come up with plans and protocols on action. But: They don’t have budget – that needs to come from elsewhere. I am expecting that if we have a real threat, we would get the budget. Right now, we don’t have a multi-billion budget.
the below is a reply to someone else's answer
There is no actual risk of any sizable asteroids hitting earth in the foreseeable future. Any preparation for it would just be a waste of money. DVK: Indeed, as mentioned earlier, we do not expect a large object to hit is in the near future. We are mainly worried about those in the size range of 20 m to 40 m, which happen on average every few tens of years to hundreds of years. And where we only know a percent of them or even less.
President Obama wanted to send a crewed spacecraft to an asteroid - in your opinion is this something that should still be done in the future, would there be any usefulness in having a human being walk/float on an asteroid's surface? DVK: It would definitely be cool. I would maybe even volunteer to go. Our current missions to asteroids are all robotic, the main reason is that it is much cheaper (but still expensive) to get the same science. But humans will expand further into space, I am sure. If we want to test human exploration activities, doing this at an asteroid would be easier than landing on a planet.
this is another reply Yes, but I am slightly biased by the fact that I work at the European astronaut centre ;) There exist many similarities to what we currently do for EVA (extra vehicular activities) operations on the International Space Station versus how we would 'float' around an asteroid. Slightly biased again, but using such a mission to test exploration technologies would definitely still have value. Thanks Obama! - AC
I've heard that some asteroids contains large amounts of iron. Is there a possibility that we might have "space mines" in the far away future, if our own supply if iron runs out? Yes, this is a topic in the field known as space mining, part of what we call Space Resources. In fact, learning how we can process material we might find on asteroids or other planetary bodies is increasingly important, as it opens up the opportunities for sustainable exploration and commercialization. Its a technology we need to master, and asteroids can be a great target for testing how we can create space mines :) - AC
By how much is DART expected to deflect Didymos? Do we have any indication of the largest size of an asteroid we could potentially deflect? PM: Didymos is a binary asteroid, consisting of a main asteroid Didymos A (~700m) and a smaller asteroid Didymos B (~150m) orbiting around A with a ~12 hours period. DART is expected to impact Didymos B and change its orbital period w.r.t. Didymos A of ~1%. (8 mins)
The size of Didymos B is the most representative of a potential threat to Earth (the highest combination of probability and consequence of impacts), meaning smaller asteroids hit the Earth more often but have less severe consequences, larger asteroids can have catastrophic consequences but their probability of hitting the earth is very very low.
the below is a reply to the above
Why is there less probability of larger asteroids hitting earth? DVK: There are less large objects out there. The smaller they are, the more there are.
the below is a reply to the original answer
Is there any chance that your experiment will backfire and send the asteroid towards earth? PM: Not at all, or we would not do that :) Actually Dimorphos (the Didymos "moon") will not even leave its orbit around Didymos. It will just slightly change its speed.
I'm sure you've been asked this many times but how realistic is the plot of Armageddon? How likely is it that our fate as a species will rely on (either) Bruce Willis / deep sea oil drillers? Taking into consideration that Bruce Willis is now 65 and by the time HERA is launched he will be 69, I do not think that we can rely on him this time (although I liked the movie).
HERA will investigate what method we could use to deflect asteroid and maybe the results will show that we indeed need to call the deep sea oil drillers.
HG
the below is a reply to the above
So then would it be easier to train oil drillers to become astronauts, or to train astronauts to be oil drillers? I do not know which one would be easier since I have no training/experience of deep see oil drilling nor becoming an astronaut, but as long as the ones that would go to asteroid have the sufficient skills and training (even Bruce Willis), I would be happy.
HG
If budget was no object, which asteroid would you most like to send a mission to? Nice question! For me, I'd be looking at an asteroid we know something about, since I would be interested in using it for testing how we could extract resources from it. So for me, I would choose Itokawa (https://en.wikipedia.org/wiki/25143_Itokawa), which was visited by Hayabusa spacecraft. So we already have some solid prospecting carried out for this 'roid! - AC
this is another reply Not sure if it counts as an asteroid, but Detlef and myself would probably choose ʻOumuamua, the first discovered interstellar object.
MM
the below is a reply to the above
Do we even have the capability to catch up to something like that screaming through our solar system? That thing has to have a heck of a velocity to just barrel almost straight through like that. DVK: Correct, that would be a real challenge. We are preparing for a mission called 'Comet Interceptor' that is meant to fly to an interstellar object or at least a fresh comet - but it will not catch up with it, it will only perform a short flyby.
https://www.esa.int/Science_Exploration/Space_Science/ESA_s_new_mission_to_intercept_a_comet
After proving to be able to land on one, could an asteroid serve as a viable means to transport goods and or humans throughout the solar system when the orbit of said asteroid proves beneficial. While it is probably quite problematic to land the payload, it could save fuel or am I mistaken? Neat idea! Wonder if anyone has done the maths on the amount of fuel you would need/save vs certain targets. - AC
PM: To further complement, the saving is quite marginal indeed because in order to land (softly) on the asteroid you actually need to get into the very same orbit of that asteroid . At that point your orbit remains the same whether you are on the asteroid or not..
can the current anti-ballistic missiles systems intercept a terminal phase earth strike asteroid? or it is better to know beforehand and launch an impacting vehicle into space? DVK: While I do see presentations on nuclear explosions to deflect asteroids at our professional meetings, I have not seen anybody yet studying how we could use existing missile systems. So it's hard to judge whether existing missiles would do the job. But in general, it is better to know as early as possible about a possible impact and deflect it as early as possible. This will minimize the needed effort.
How much are we prepared against asteroid impacts at this moment? DVK: 42… :-) Seriously – I am not sure how to quantify ‘preparedness’. We have international working groups in place, mentioned earlier (search for IAWN, SMPAG). We have a Planetary Defence Office at ESA, a Planetary Defense Office at NASA (who spots the difference?), search the sky for asteroids, build space missions… Still we could be doing more. More telescopes to find the object, a space-based telescope to discover those that come from the direction of the Sun. Different test missions would be useful, … So there is always more we could do.
Have you got any data on the NEO coverage? Is there estimations on the percentage of NEOs we have detected and are tracking? How can we improve the coverage? How many times have asteroids been able to enter earths atmosphere without being detected beforehand? Here’s our recently updated infographics with the fraction of undiscovered NEOs for each size range: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
As expected, we are now nearly complete for the large ones, while many of the smaller ones are still unknown.
In order to improve coverage, we need both to continue the current approach, centered on ground-based telescopes, and probably also launch dedicated telescopes to space, to look at the fraction of the sky that cannot be easily observed from the ground (e.g., towards the Sun).
Regarding the last part of your question, small asteroids enter the Earth atmosphere very often (the infographics above gives you some numbers), while larger ones are much rarer.
In the recent past, the largest one to enter our atmosphere was about 20 meters in diameter, and it caused the Chelyabinsk event in 2013. It could not be detected in advance because it came from the direction of the Sun.
We have however detected a few small ones before impact. The first happened in 2008, when a ~4-meter asteroid was found to be on a collision course less than a day before impact, it was predicted to fall in Northern Sudan, and then actually observed falling precisely where (and when) expected.
MM
this is another reply >After
DVK: And to add what MM said - Check out http://neo.ssa.esa.int. There is a ‘discovery statistics’ section which provides some of the info you asked about. NASA is providing similar information here https://cneos.jpl.nasa.gov/stats/. To see the sky which is currently covered by the survey telescopes, you need to service of the Minor Planet Center which we all work together with: http://www.minorplanetcenter.org, ‘observers’, ‘sky coverage’. That is a tool we use to plan where we look with our telescopes, so it is a more technical page.
Are there any automatic systems for checking large numbers of asteroids orbits, to see if the asteroid's orbit is coming dangerously close to Earth, or is it done by people individually for every asteroid? I ask it because LSST Rubin is coming online soon and you know it will discover a lot of new asteroids. Yes, such systems exist, and monitor all known and newly discovered asteroids in order to predict possible future impacts.
The end result of the process is what we call "risk list": http://neo.ssa.esa.int/risk-page
It is automatically updated every day once new observational data is processed.
MM
What are your favourite sci-fi series? DVK: My favorites are ‘The Expanse’, I also liked watching ‘Salvation’. For the first one I even got my family to give me a new subscription to a known internet streaming service so that I can see the latest episodes. I also loved ‘The Jetsons’ and ‘The Flintstones’ as a kid. Not sure the last one counts as sci-fi though. My long-time favorite was ‘Dark Star’.
this is another reply Big fan of The Expanse at the moment. Nice, hard sci-fi that has a good impression of being grounded in reality - AC
this is another reply When I was a kid I liked The Jetsons, when growing up Star Trek, Star wars and I also used to watch with my sister the 'V'.
HG
When determining the potential threat of a NEA, is the mass of an object a bigger factor or size? I'm asking because I'm curious if a small but massive object (say, with the density of Psyche) could survive atmospheric entry better than a comparatively larger but less massive object. The mass is indeed what really matters, since it’s directly related with the impact energy.
And as you said composition also matters, a metal object would survive atmospheric entry better, not just because it’s heavier, but also because of its internal strength.
MM
What are your thoughts on asteroid mining as portrayed in sci-fi movies? Is it feasible? If so would governments or private space programs be the first to do so?What type of minerals can be found on asteroids that would merit the costs of extraction? Certainly there is valuable stuff you can find on asteroids. For example, the likely easiest material you can harvest from an asteroid would be volatiles such as H2O. Then you have industrial metals, things like Iron, Nickel, and Platinum group metals. Going further, you can break apart many of the oxide minerals you would find to get oxygen (getting you closer to producing rocket fuel in-situ!). Its feasible, but still needs alot of testing both here on Earth and eventually needs to be tested on a target. It may be that governments, via agencies like ESA or NASA, may do it first, to prove the principles somewhat, but I know many commercial entities are also aggresively working towards space mining. To show you that its definitely possible, I'd like to plug the work of colleagues who have processed lunar regolith (which is similar to what you may find on asteroids) to extract both oxygen and metals. Check it out here: http://www.esa.int/ESA_Multimedia/Images/2019/10/Oxygen_and_metal_from_lunar_regolith
AC
Will 2020's climax be a really big rock? DVK: Let's hope not...
Considering NASA, ESA, IAU etc. is working hard to track Earth-grazing asteroids, how come the Chelyabinsk object that airburst over Russia in 2013 came as a total surprise? The Chelyabinsk object came from the direction of the Sun, where unfortunately ground-based telescopes cannot look at. Therefore, it would not have been possible to discover it in advance with current telescopes. Dedicated space telescopes are needed to detect objects coming from this direction in advance.
MM
the below is a reply to the above
Is this to say that it was within specific solid angles for the entire time that we could have observed it given its size and speed? Yes, precisely that. We got unlucky in this case.
MM
Have any of you read Lucifer's Hammer by Larry Niven? In your opinion, how realistic is his depiction of an asteroid strike on Earth? DVK: I have – but really long ago, so I don’t remember the details. But I do remember that I really liked the book, and I remember I always wanted to have a Hot Fudge Sundae when reading it.
I was thinking about the asteroid threat as a teen and came up with this ideas (Hint: they are not equally serious, the level of craziness goes up real quick). Could you please comment on their feasibility? 1. Attaching a rocket engine to an asteroid to make it gradually change trajectory, do that long in advance and it will miss Earth by thousands of km 2. Transporting acid onto asteroid (which are mainly metal), attaching a dome-shaped reaction chamber to it, using heat and pressure to then carry out the chemical reaction to disintegrate asteroids 3. This one is even more terrible than a previous one and totally Dan Brown inspired — transporting antimatter on asteroid, impacting and causing annihilation. Thank you for this AMA and your time! DVK: Well the first one is not so crazy, I have seen it presented... the difficulty is that all asteroids are rotating in one way or another. So if you continuously fire the engine it would not really help. You'd need to switch the engine on and off. Very complex. And landing on an asteroid is challenging too. Just using the 'kinetic impactor' which we will test with DART/Hera (described elsewhere in this chat) is simpler. Another seriously proposed concept is to put a spacecraft next to an asteroid and use an ion engine (like we have on our Mercury mission BepiColombo) to 'push' the asteroid away.
As for 2 and 3 I think I will not live to see that happening ;-)
What is the process to determine the orbit of a newly discovered asteroid? The process is mathematically quite complex, but here's a short summary.
Everything starts with observations, in particular with measurements of the position of an asteroid in the sky, what we call "astrometry". Discovery telescopes extract this information from their discovery images, and make it available to everybody.
These datapoints are then used to calculate possible trajectories ("orbits") that pass through them. At first, with very few points, many orbits will be possible.
Using these orbits we can extrapolate where the asteroid will be located during the following nights, use a telescope to observe that part of the sky, and locate the object again.
From these new observations we can extract new "astrometry", add it to the orbit determination, and see that now only some of the possible orbits will be compatible with the new data. As a result, we now know the trajectory better than before, because a few of the possible orbits are not confirmed by the new data.
The cycle can then continue, with new predictions, new observations, and a more accurate determination of the object's orbit, until it can be determined with an extremely high level of accuracy.
MM
What are some asteroids that are on your "watchlist"? We have exactly that list on our web portal: http://neo.ssa.esa.int/risk-page
It's called "risk list", and it includes all known asteroids for which we cannot exclude a possible impact over the next century. It is updated every day to include newly discovered asteroids, and remove those that have been excluded as possible impactors thanks to new observations.
MM
the below is a reply to the above
That's quite a list!! Do you guys ever feel stressed or afraid when you have to add another dangerous candidate (and by dangerous I mean those above 200m) is added to this Risk List? Yes, when new dangerous ones are added it's important that we immediately do our best to gather more data on them, observing them with telescopes in order to get the information we need to improve our knowledge of their orbit.
And then the satisfaction of getting the data needed to remove one from the list is even greater!
MM
What inspired you to go into this field of study? I was fascinated by astronomy in general since I was a kid, but the actual "trigger" that sparked my interest in NEOs was a wonderful summer course on asteroids organized by a local amateur astronomers association. I immediately decided that I would do my best to turn this passion into my job, and I'm so happy to have been able to make that dream come true.
MM
this is another reply DVK: I started observing meteors when I was 14, just by going outside and looking at the night sky. Since then, small bodies in the solar system were always my passion.
As a layperson, I still think using nuclear weapons against asteroids is the coolest method despite better methods generally being available. Do you still consider the nuclear option the cool option, or has your expertise in the field combined with the real-life impracticalities made it into a laughable/silly/cliche option? DVK: We indeed still study the nuclear option. There are legal aspects though, the ‘outer space treaty’ forbids nuclear explosions in space. But for a large object or one we discover very late it could be useful. That’s why we have to focus on discovering all the objects out there as early as possible – then we have time enough to use more conventional deflection methods, like the kinetic impactor (the DART/Hera scenario).
It seems like doing this well would require international cooperation, particularly with Russia. Have you ever reached out to Russia in your work? Do you have a counterpart organization there that has a similar mission? DVK: Indeed international cooperation is important - asteroids don't know about our borders! We work with a Russian team to perform follow-up observations of recently discovered NEOs. Russia is also involved in the UN-endorsed working groups that we have, IAWN and SMPAG (explained in another answer).
how much can experts tell from a video of a fireball or meteor? Can you work out what it's made of and where it came from? https://www.reddit.com/space/comments/hdf3xe/footage_of_a_meteor_at_barrow_island_australia/?utm_source=share&utm_medium=web2x If multiple videos or pictures, taken from different locations, are available, then it's possible to reconstruct the trajectory, and extrapolate where the object came from.
Regarding the composition, it's a bit more difficult if nothing survives to the ground, but some information can be obtained indirectly from the fireball's color, or its fragmentation behavior. If a spectral analysis of the light can be made, it's then possible to infer the chemical composition in much greater detail.
MM
I've always wanted to know what the best meteorite buying site is and what their average price is?? DVK: Serious dealers will be registered with the 'International Meteorite Collectors Association (IMCA)' - https://www.imca.cc/. They should provide a 'certificate of authenticity' where it says that they are member there. If you are in doubt, you can contact the association and check. Normally there are rough prices for different meteorite types per gram. Rare meteorites will of course be much more expensive than more common ones. Check the IMCA web page to find a dealer close to you.
Just read through Aidans link to the basaltic rock being used as a printing material for lunar habitation. There is a company called Roxul that does stone woven insulation that may be able to shed some light on the research they have done to minimize their similarity to asbestos as potentially carcinogenic materials deemed safe for use in commercial and residential applications. As the interior surfaces will essentially be 3D printed lunar regolith what are the current plans to coat or dampen the affinity for the structure to essentially be death traps for respiratory illness? At least initially, many of these 3d printed regolith structures would not be facing into pressurised sections, but would rather be elements placed outside and around our pressure vessels. Such structures would be things like radiation shields, landing pads or roadways, etc. In the future, if we move towards forming hermetically sealed structures, then your point is a good one. Looking into terrestrial solutions to this problem would be a great start! - AC
What kind of career path does it take to work in the asteroid hunting field? It's probably different for each of us, but here's a short summary of my own path.
I became interested in asteroids, and near-Earth objects in particular, thanks to a wonderful summer course organized by a local amateur astronomers association. Amateur astronomers play a great role in introducing people, and young kids in particular, to these topics.
Then I took physics as my undergrad degree (in Italy), followed by a Ph.D. in astronomy in the US (Hawaii in particular, a great place for astronomers thanks to the exceptional telescopes hosted there).
After finishing the Ph.D. I started my current job at ESA's NEO Coordination Centre, which allowed me to realize my dream of working in this field.
MM
this is another reply DVK: Almost all of us have a Master's degree either in aerospace engineering, mathematics, physics/astronomy/planetary science, or computer science. Some of us - as MM - have a Ph.D. too. But that's not really a requirement. This is true for our team at ESA, but also for other teams in other countries.
What is the likelihood of an asteroid hitting the Earth In the next 200 years? It depends on the size, large ones are rare, while small ones are much more common. You can check this infographics to get the numbers for each size class: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
MM
Have you played the Earth Defence Force games and if you have, which one is your favourite? No I have not played the Earth Defence Force games, but I just looked it up and I think I would liked it. Which one would you recommend?
HG
How close is too close to earth? Space is a SUPER vast void so is 1,000,000 miles close, 10,000,000? And if an asteroid is big enough can it throw earth off its orbit? DVK: Too close for my taste is when we compute an impact probability > 0 for the object. That means the flyby distance is zero :-) Those are the objects on our risk page http://neo.ssa.esa.int/risk-page.
If an object can alter the orbit of another one, we would call it planet. So unless we have a rogue planet coming from another solar system (verrry unlikely) we are safe from that.
How can I join you when I'm older? DVK: Somebody was asking about our career paths... Study aerospace engineering or math or physics or computer science, get a Masters. Possibly a Ph.D. Then apply for my position when I retire. Check here for how to apply at ESA: https://www.esa.int/About_Us/Careers_at_ESA/Frequently_asked_questions2#HR1
How much is too much? DVK: 42 again
Are you aware of any asteroids that are theoretically within our reach, or will be within our reach at some point, that are carrying a large quantity of shungite? If you're not aware, shungite is like a 2 billion year old like, rock stone that protects against frequencies and unwanted frequencies that may be traveling in the air. I bought a whole bunch of the stuff. Put them around the la casa. Little pyramids, stuff like that. DVK: If I remember my geology properly, Shungite forms in water sedimental deposits. This requires liquid water, i.e. a larger planet. So I don't think there is a high chance to see that on asteroids.

Superposition: Transcript of Audio Essay Episode 35

Hi. It's Eric with some thoughts for this week's audio essay on the topic of superposition. Now, to those of you in the know, superposition is an odd word, in that it is the scientific concept we reach for when trying to describe the paradox of Schrodinger's cat and the theory and philosophy of quantum measurement. We don't yet know how to say that the cat is both dead and alive at the same time rigorously, so we fudge whatever is going on with this unfortunate feline and say that the cat and the quantum system on which its life depends are a mixture of two distinct states, that are somehow commingled in a way that has defied a satisfying explanation for about a century. Now, I'm usually loath to appeal to such quantum concepts in everyday life, as there is a veritable industry of people making bad quantum analogies. For example, whenever you have a non-quantum system that is altered by its observation, that really has nothing to do with the Heisenberg uncertainty principle. Jane Goodall's chimpanzees are almost certainly altered in their behavior due to her presence. But there is likely no competent quantum theorist who would analogize chimps to electrons, and Goodall to our mission observable, executing a quantum observation. Heisenberg adds nothing other than physics-envy to the discussion of an entirely classical situation such as this.
However, I have changed my mind in the case of superposition, as I would now like to explain. To begin with, superposition isn't a quantum phenomenon. For example, imagine that you'd come from Europe to Australia, and that you had both euros and Swiss francs in your pockets. You might then be said to be in a superposition, because you have pocket change in both euros and francs rather than a pure state of only one currency or the other. The analog of the physical observable in this situation would be something like a multiple-choice question found on a landing card about the contents of your pockets. Here, it is easy to see the danger of this set up. Assuming you have three times as much value in euros as you do in francs, what happens when you get a question that doesn't include your situation as an answer? What if the landing card asked, is all of your change in A) euros or B) Swiss francs, with no other options available? Well, this as stated, is a completely classical superposition problem, having nothing to do with quantum theory. Were you to have such a classical question asked of you like this, there would have been no way for you to answer. However, if the answer were on the multiple-choice menu, there would be no problem at all, and you would give a clear answer determined by the state of your pockets. So, if the state in question isn't on the multiple-choice menu, the classical world is forced to go mute, as there is no answer determined by the system; whereas if it is found on the list of allowable choices, the answer is then completely determined by the system’s state at the time that the question was asked.
Oddly, the quantum world is, in a way, exactly as deterministic as the classical one just described, despite what you may have heard to the contrary. In order to understand this, we’ll have to introduce a bit of jargon. So long as the system (now called the Hilbert space state) is on the list of answers (technically called the system of Eigenvectors) corresponding to the question (now called a quantum observable) the question will return a completely deterministic answer (technically called the Eigenvalue corresponding to the state Eigenvector.) These are, in a sense, good questions in quantum theory, because the answer corresponding to the state of the system actually appears as one of the multiple-choice options.
So, if that is completely deterministic, well then what happened to the famous quantum probability theory and the indeterminacy that we hear so much about? What if I told you that it were 100% confined to the situation which classical theory couldn't handle either? That is, quantum probability theory only becomes relevant when you ask bad quantum questions, where the state of the system isn't on the list of multiple-choice answers. When the landing card asked if all your change were completely in euros or only in francs, the classical system couldn't answer because three times the value of your Swiss francs were held in euros, so no answer could be determined. But if your pocket change were somehow quantum, well then you might find that 75% of the time your pocket coins would bizarrely turn into pure euros, and would bewilderingly turn into pure francs 25% of the time just by virtue of your being asked for a measurement by the landing card. In the quantum theory, this is due to the multiple-choice answers of the so-called observable, represented by the landing card question, not being well-suited to the mixed state of your pockets in a superposition between euros and francs. In other words, quantum theory gets probabilistic only where classical theory went mute. All of the indeterminacy appears to come from asking bad multiple-choice questions in both the classical and quantum regimes, in which the state of the system doesn't fit any given answer.
Quite honestly, I've never heard a physicist rework the issue of quantum probabilities in just this way, so as to highlight that the probabilistic weirdness comes only from the quantum being overly solicitous, and accommodating really bad questions. For some reason, they don't like the idea of calling an observable that doesn't have the state of the system as an allowable answer, a bad question. But that is precisely why I do like it. It points out that the quantum is deterministic where the classical theory is deterministic, and only probabilistic where the classical theory is mute. And this is because it is weirdly willing to answer questions that are, in a sense that can be made precise, bad questions to begin with. That doesn't get rid of the mystery, but it recasts it so it doesn't sound quite so weird. The new question is, why would a quantum system overcompensate for the lousy questions being posed, when the classical system seems to know not to answer?
So why bring any of this up? Well, the first reason is that I couldn't resist sneaking in a personal reformulation of the quantum measurement problem that most people will have never considered. But the second reason is that I have come to believe that we are wasting our political lives on just such superposition questions.
For example, let's see if we can solve the abortion debate problem right now on this podcast using superposition; as it is much easier than the abortion problem itself. The abortion debate problem is that everyone agrees that before fertilization there is no human life to worry about. And that after a baby is born, there is no question that it has a right to live. Yet, pro-choice and pro-life activists insist on telling us that the developing embryo is either a mere bundle of cells suddenly becoming a life only when born, or a full-fledged baby the moment the sperm enters the egg. You can guess my answer here. The question of, is it a baby's life or a woman's choice, is agreed-upon by everyone before fertilization or following birth because the observable in question has the system as one of the two multiple-choice answers in those two cases. However, during the process of embryonic development, something miraculous is taking place that we simply don't understand scientifically. Somehow, a non-sentient blastula becomes a baby by a process utterly opaque to science, which as yet has no mature theory of consciousness. The system in utero is in a changing and progressing superposition tilted heavily towards not being a baby at the beginning, and tilted heavily towards being one at the end of the pregnancy. But the problem here is that we have allowed the activists, rather than the embryologists and developmental biologists, to hand us the life versus choice observable, with its two terrible multiple-choice options. If we had let the embryologist set the multiple-choice question, there would be at least 23 Carnegie stages for the embryo, before you even get to fetal development. But instead of going forward from what we both know and don't know with high confidence about the system, we are instead permanently deranged by being stuck with Schrodinger's embryo by the activists who insist on working backwards from their political objectives.
So, does this somehow solve the abortion issue? Of course not. All it does, is get us to see how ridiculously transparent we are in our politics, that we would allow our society to be led by those activists who would shoehorn the central scientific miracle of human development into a nutty political binary of convenience. We don't even think to ask, who are these people who have left us at each other's throats, debating an inappropriate multiple-choice question that can never be answered? Well, in the spirit of The Portal, we are always looking for a way out of our perennial problems to try to find an exit. And I think that the technique here of teaching oneself to spot superposition problems in stalemated political systems, brings a great deal of relief to those of us who find the perspective of naïve activism a fairly impoverished worldview. The activist mindset is always trying to remove nuanced selections that might better match our world’s needs from among the multiple-choice answers, until it finds a comical binary. Do you support the war on drugs, yes or no? Are you for or against immigration? Should men and women be treated equally? Should we embrace capitalism, or choose socialism? Racism: systemic problem or convenient excuse? Is China a trading partner or a strategic rival? Has technology stagnated, or is it in fact racing ahead at breakneck speed? Has feminism gone too far, or not far enough? In all of these cases, there is an entire industry built around writing articles that involve replacing conversations that might progress towards answers and agreement, with simple multiple-choice political options that foreclose all hope. And in general, we can surmise when this has occurred because activism generally leaves a distinct signature, where the true state of a system is best represented as a superposition of the last two remaining choices that bitterly divide us, handed us by activists.
So, I will leave you with the following thought. The principle of superposition is not limited to quantum weirdness, and it may be governing your life at a level that you never considered. Think about where you are most divided from your loved ones politically. Then ask yourself, when I listen to the debates at my dinner table, am I hearing a set of multiple-choice answers that sound like they were developed by scholars interested in understanding, or by activists who are pushing for an outcome? If the latter, think about whether you couldn't make more progress with those you love by recognizing that the truth is usually in some kind of a superposition of the last remaining answers pushed by the activists. But you don't have to accept these middlebrow binaries, dilemmas and trilemmas. Instead, try asking a new question. If my loved ones and I trashed the terms of debate foisted upon us by strangers, activists and the news media, could we together fashion a list of multiple choice answers that we might agree contain an answer we all could live with, and that better describes the true state of the system? I mean, do you really want open or closed borders? Do you really want to talk about psilocybin and heroin in the same breath? Do you really want to claim that there is no systemic oppression, or that it governs every aspect of our lives? Before long, it is my hope that you will develop an intuition that many long-running stalemated discussions are really about having our lives shoehorned by others into inappropriate binaries that can only represent the state of our world as a superposition of inappropriate and simplistic answers that you never would have chosen for yourself.

Entering a Credential Program for Mathematics

Hello all and new to this forum, and entering the credential program for Mathematics teaching in the fall. Down the road when I am teaching I was curious about feed back for an extra credit question I plan on using for every test. I plan on having one extra credit question be just a number, the amount of extra credit being offered is based on the creativity of their answer with a cap I haven't set yet. If they surprise me then they get a bonus say 2.
For example if I put down 23. They can simply rewrite it in a different numeration, could be Roman Numeral, Inupiaq Numerals, Chinese counting rods, binary, or even modulo some number, just a small list of countless options. OR They can create an equation of which 23 is the answer to the question
The reason I am thinking about doing this is I know that not everyone is going to go to college, nor even trade schools. But if they see a problem and take the time to find a creative solution to the problem that could be a way of life. Anyways just want some feedback on this.

First Contact - Part Twenty-Three

[first] [prev] [next]
The Devastator class Precursor machine was the size of a large metropolis. Full of ground combat machines, air superiority machines, mining and reclamation machines that could move under their own power and were festooned with a thousand weapons. It was over a hundred million years old and had exterminated life on planets with its massive guns, with biowarfare, with chemical warfare, and with good old nuclear fire. It had wiped away planet after planet of the enemies cattle, the hated enemy's food sources, before finally following orders of the greater machines and going into sleep mode on a dead world.
Now the call had sounded out. Cattle had run amuck, even learning jumpspace technology. That meant the enemy had not been defeated, that his food source had multiplied into the trillions while the Devastator had slumbered, slowly sinking into the crust of the barren planet.
That was of no moment. Cattle could not fight back, that was why they were cattle. They knew nothing but safety and the security of numbers, willing to trade their own safety for the suffering of others. The cattle willingly marched into the pens if the pens promised safety.
The cattle were not the problem.
It was the feral intelligence that were the problem. Feral intelligence could fight. They knew nothing else. They cared for nothing else. A feral intelligence always destroyed itself once it could wield nuclear fire. The universe had proved it over and over even before the great machine had gone into slumber.
The call had sounded out, informing the machines that cattle had broken loose from the pens. The Devastator had computed that the problem would be solved quickly, with a minimum expenditure of resources, and had started to go back into slumber.
That was when the second call sounded. A feral intelligence had mastered FTL travel and had turned all of their unthinking violence against the Precursor war machines.
The Devastator considered the chances of the feral intelligence lasting long enough to withstand his brethren's assault, withstand purification and pacification.
It was mathematically insignificant. Not zero, but close enough that it required an application of resource driven computation to analyze it.
Feral intelligences always destroyed themselves.
The Devastator knew this. Had it encoded into its very bones. It did not feel the electronic version of caution as it moved into the planetary system, exiting faster than light travel. It screeched out its warcry as it exited into the system and brought up its scanners.
It felt the electronic version of anticipation as it detected orbital facilities around two planets that teemed with billions of cattle, as it tasted jumpspace wake trails, as it felt the presence of a small, insignificant amount of cattle space vessels arrayed to attempt to stand against it near the outer gas giant.
It was a waste of resources.
Cattle could not withstand machines.
It was as solid a fact as radioactive decay and as impossible to stop.
It roared and turned to accelerate toward the cattle ships waiting on the other side of the gas giant, letting them know the futility of their resistance and that nothing could stop it from destroying them any more than they could stop entropy.
It felt electronic satisfaction as nearly 10% of the cattle ships broke formation and fled for the planets.
The cattle ships lit their engines, trying to keep the gas giant between them and the great Precursor machine but the Devastator knew it would do no good. It would ensure they were caught mathematically opposite of it and begin launching subsidiary craft to destroy them and reclaim the resources of their wreckage.
The Devastator slowed as it approached the gas giant, ancient code pulsing impulses into the electronic brain at the mathematical certainty of destroying the cattle's defenses and thus weakening the hated enemy.
pssst... over here...
The transmission was in binary. The basic code, on a low band that the Devastator used to contact and exchange data with its peers. The signal origin was close, just behind it, in the gap between two point defense radars.
The Devastator tumbled as it slowed, searching with its senses to check that tiniest of gaps in its sensors. It could detect nothing out of the ordinary. The fact that the gas giant had a high level of hydrocarbon and pseudo-organic compounds was a high certainty with most gas giants of that size. The Devastator cast around, knowing the cattle had not sent that transmission.
psst... here...
This time the transmission was only a few hundred kilometers above the hull, right behind the main guns of battery-eight, between the massive cannons and the sensor array, in a gap in the coverage caused by space dust not yet cleared from the array. The Devastator ensured the cattle vessels were on the other side of the gas giant as it cast around again, looking for what could possibly be sending the message on that particular channel and rotating again to either force the transmitter to move away or hit the hull of massive Devastator.
...right here...
The Devastator felt the computer version of anxiety. A new factor had entered the computation. The voice, and the binary signal somehow had a voice, a whispering, tickling, hissing faint signal of binary on a wavelength just above the screaming particles of the foam between realspace and subspace. This time the voice had come from just below the Devastators thick hull, beneath the vessel, in a gap between the sensors in a place where its own orbital guns would not dazzle the sensors. The Devastator rolled, getting the upper sensors into place in a graceful sideways roll.
Nothing.
The Devastator was barely tracking the cattle. They were of no moment. Something was whispering on a bandwidth that was beyond organic abilities. Could it be a damaged ally, barely able to whisper for electronic assistance?
...I see you...
The Devastator heard the signal hiss to life, trickling out of empty space a few hundred kilometers away. It felt of a surge of self-defense protocol override everything else and it unleashed all of its gun at the empty space, suspecting that this possible enemy may be using some type of photo-passthrough adaptive camouflage.
Nothing.
The Devastator felt the self-preservation protocols wake up and fill some of its processors. That signal had originated from that point! Even a dust-speck would have been detected by its scanner arrays, nothing could have escaped the terrawatts of death it had unleashed.
...touch...
The Devastator felt a physical TOUCH on its housing, the decameters thick armor around the massive computer core that made up its brain. That was impossible! It was in the center of the ship, protected by layer after layer of armor, defensive mechanisms, sensors, but yet it had felt something touch the housing, press against it lightly, only a few tickles of the suggestion of pressure per square micrometer but a touch all the same.
There was a slight ripple in realspace only a few meters above the hull and the Devastator pushed itself away, firing every weapon it could bring to bear on the spot only a few atoms wide, all of its sensor questing, seeking, hunting in electronic desperation to find out what was transmitting, what was touching it!
...here...
The word was whispered from only a few meters away from the electronic "brain" of the Devastator, inside the protective housing, inside the field that would shut down biological neural function and even primitive artificial intelligences!
The Devestator felt self-protection and self-preservation programs never before accessed come online and flood into its RAM as the word was whispered at it from inside the final layer of protection.
Massive nCv cannons lowered, the housings screamed as the Devastator pushed them past the limit, to aim at its own hull. It opened fire, trying to claw into its own body in the electronic version of panic to get whatever was inside it out of it.
All of its sensors were directed into its own body. It no longer even bothered with tracking the cattle fleet. Even its astrogation and navigation programs, even the ones responsible to maintain orbit around the gas giant, were desperately racing through the circuitry, desperate to find whatever was whispering.
...over here...
The whisper was over it, on top of it, and carried sidecode of a mathematically impossible jumble of electrons arrayed in an impossible manner, with quarks whirling through electron valences, antimatter electrons in the nucleus, preons stretched to massive size taking up the place of neutrons, all with jumbling strangled mathematical codes that made no sense.
The Devastator's brain burned out the receptors to defend itself from such electronic madness.
And felt a touch upon one of the upper lobes of its quantum computer brain.
...over here...
The Devastator was throwing antivirus software out, slamming firewalls against each other, crushing ports into electronic ghosts, doing anything it could to keep out the voice. Inside the Main Computer Housing the last resort lasers began raking across anything that didn't match the original blueprints, burning away dust, odd quarks and electrons, destroying an upgraded maintenance robot that was desperately trying to detect what had touched its carapace.
From deep within the gas giant tentacles hundreds of miles long rose toward the Devastator, the ends slowly unrolling as massive graviton assisted 'suckers' on the inside of the tentacles deployed razored thorns of dark matter infused psuedo-bone.
The Devastator detected the tentacles just as they wrapped around it, the thick psuedo-protoplasmic tentacles that were thick with dark matter squeezing the Devastator's hull with impossible strength as meters thick muscles flexed with enough strength to crush the hull into itself and shatter armor over a kilometer thick.
Gibbering, raving, SCREAMING in something beyond electronic self-preservation programs would normally allow, the Devastator began to break apart, caught in the grips of the tentacles, being pulled into the gas giant.
...delicious delicious delicious...
The Devastator heard from inside its own mind as a beak nearly twenty kilometers long crushed its hull.
HELP ME, BROTHERS, PLEEEEEASE!
The beak closed and the Devastators brain flashed out of existence as the hull crushed around it.
The last thing it felt was something new. It threw data out with the cry for assistance to let its brethren know the last experience hashed data compile it had undergone. The data made no sense to the other Precursor war machines that heard the cry. A biological entity could have explained it.
Terror.
And despair.
A Desolation Class precursor war machine was assigned to discover what had caused the Devastator's intelligence collapse.
It dropped into the system and found no trace of its mechanical brethren.
Just some cattle species space craft hiding behind a gas giant, obviously intending ambushing it.
Feeling the electronic version of anticipation it moved into orbit around the gas giant, intending on forcing the cattle ships to move out of line of sight with their worlds if they wanted to stay on the opposite side of the gas giant from it. It updated its computations based on the fact that 10% of the cattle's ships had fled away from it.
It had already computed out the battle. It knew how the battle would go. While it could not detect any signs of its little brother it computed that it would simply destroy the cattle and then search. It powered up its guns and began to move it's metropolis sized bukk slowly to
...psst... over here...
---------------------
The stellar system was infested with a known species of cattle, obviously seeking to rise above themselves as the Jotun class Precursor vessel arrived in the system. It released its roar to let the cattle know not only why but who was destroying them to reclaim the resources they so foolishly squandered. It began unthawing ancient bioweapons and chemical weapons known to work upon that race, began reconfinguring its war machines to forms that had exterminated who planets of the cattle during the time that the Precursor war machine had been forged. The Jotun released over a hundred Devastator classes from its hull, computed the battle plan as they came to electronic life, then informed them of how the extermination and reclamation would progress.
They were barely into the system when a high energy signal appeared, rising from the most heavily infested planet and moving toward them. The Jotun ordered a diagnostic of its scanners when the first information came in.
It was apparently moving at .85C, but yet its progress toward the Jotun and its smaller brethren on the system map showed it moving at almost 22C. That made no sense. An object moving at .85C only approached at .85C, not at 22C.
By the time the diagnostic was done the object had gotten a third of the way toward the Jotun, crossing a quarter of the radius of the system.
The scanners reported that the energy signal, with the strength normally reserved for a quasar, was not a massive ship or an oncoming armada interlinked together, but was simply a single object the size of cattle.
Again the Jotun ordered a complete low level full diagnostic on all systems. Risky, but any object radiating that much power and moving at two different speeds required all systems were working at optimum efficiency.
It had finished just as the small object came to a stop. The Jotun focused scanning arrays on it, turning up the power to the point that it would boil away meters of armor.
The figure was a primate, half of it made up of robotics. It had some kind of sheet of material floating behind it, the movement suggesting some kind of current was effecting it and making it undulate. It was dressed in two primary colors, red and blue, had its lower legs pressed together with the toes pointing down and the upper limbs crossed over its chest, one biological the other mechanical.
"So, you're the new punk everyone's talking about," The figure stated over a wide bandwidth of wavelengths. Oddly enough, to the Jotun's sensors, sound waves travelled through vaccum almost instantly across a light second to its sensors.
The Jotun tried to compute how sound waves moved faster than light through a vacuum.
Instead of answering the Jotun and its brethren opened fire.
The figure arced through the beams as if light speed weapons were moving slow enough for it to just compute and swoop around in a resource wasting corkscrew. The Jotun realized it was racing for one of the Devastators, one clenched fist held in front of it.
The Jotun computed a 99.99999999999998 chance that the small primate would splatter against the hull of the Devastator and started to turn its attention to computing a missile firing resolution for missile bay 148 to destroy an orbital facility around the nearest planetoid.
The small figure punched straight through the Devastator, as if it was made of nebula gas instead of density collapsed armor, high tensile ceramics, and reinforced internal spaces. The Devastator's computer core shrieked with self-preservation code snippets as the figure exited the opposite side of the Devastator holding the Primary Computer Core CPU0 in its fist. It paused, looked at its fist, and shot beams of red energy from its eyes, destroying the computer core in a puff of atomic smoke.
The Jotun yanked its processing power back to the figure as it raked its gaze, still emitting beams of red energy that left ripples in jumpspace, across the side of another Devastator, tearing it open like it was made of fragile tissue, the red beams reducing the computer core to its component atoms with the briefest of touches.
Several computational nodes collapsed when trying to analyze the beams, suffering the fatal CANNOTDIVIDEBYZERO shriek of despair before imploding on themselves.
The Jotun stared in electronic shock, all his computational power trying to compute how the tiny half-mechanical primate could grab a hold on the front armor of one of the Devastators, and without any source to exert leverage against, physically move a city-sized spacecraft in an arc and throw it against another one.
According to scanners the "thrown" Devastator was only moving at 0.001C for inertia purposes yet crossed the hundreds of kilometers to the next Devastator in an amount of time that would require it to be moving at 6C.
CANNOTDIVIDEBYINFINITYDIVIDEDBYZERO
The Jotun cut loose with its weapons and goggled in electronic confusion as most of the beams and slugs were avoided, slapped aside, or ignored.
Until a nCv (near C velocity) slug the size of skyscraper hit it dead center of the chest, the impact point looking only the size of a soda can.
The Jotun's processors struggled to understand how something that size had only made an impact smaller than itself.
CANNOTSUBDIVIDETWINKIESBYCHEETOSBYZERO
The figure looked down at the tear in its suit, at the bruised biological flesh that had been exposed, then at the Jotun. It lifted a hand, extended the first finger next to the opposable thumb, and slowly waved it back and forth.
"That might have worked against a Galactic Class Klark, but it was pathetic against an Apokalypse level Injustice MCLXI Cyber-Clark," The figure said, the tone calm and confident. The meanings behind the words were gibberish to the Jotun, who devoted processor cycles to try to decode the meanings for any hint on how to defeat the creature before it.
The Jotun computed that retreat was the only option as the small primate figure set about destroying the last of the Devastators.
It began activating the engines when the primate suddenly turned in place.
"No you don't," It snapped.
Again, it sounded as if the Central Computer Core Housing had been set to atmosphere so that sound waves could be heard within it, yet a quick check showed the housing was still at almost perfect vacuum.
Sound waves cannot travel through space, a hundred diagnostic programs computed.
And promptly crashed.
Those red beams lanced out again and the Jotun braced in the microsecond it had.
It was like being brushed by the solar flare of a red giant concentrated into a piercing lance of nuclear fire. Armor exploded from energy transfer, slagged away from thermal transfer, or just ceased to exist as ravening atoms usually only found in the photosphere of a dying red sun attacked the atoms of the armor. The beam tore through mile after mile of internal structure, the figure still emitting the beam from its tiny eyes.
The Helljump engines exploded when the light touched them.
The Jotun listed, pouring debris and a cloud of atomized armor from the wound that completely bisected it.
"Done. Now let's see the face of the enemy," The figure said, slapping its hands together after it crashed/flew through the last Devastator. It reoriented on the Jotun and began to "slowly" drift toward the Jotun, moving at only 0.000003C according to some scanners but crossing the distance as if it was moving at 1.5C.
The figure flexed its primate hands and a slow smile spread across its face.
"I can't wait to rip away your housing and see you with my own eyes," the figure said, the sound waves again travelling inside the vacuum of the strategic housing.
The Jotun tried to react but the figure was suddenly pushing open armor with its two hands.
Self-preservation programs crashed trying to compute how to prevent impossibility itself from breaching critical spaces. Self-defense programs tried to compute how to defend against something that did nothing but radiate impossibility around it.
The Jotun knew what it had to do as the creature tore open the last of the hardened bulkheads protecting the Strategic Housing.
It detonated the antimatter reactor that powered the "brain" as the figure tore through the Strategic Housing and laid eyes upon the supercomputer core.
It had computed that not even the figure could withstand the direct assault of kiloton of pure antimatter point blank.
The explosion completely consumed the Jotun.
When the ravening energy disappated the red and blue figure was lying in blackness, surrounded by an expanding ring of debris and energy.
It stared at the stars and mouthed a single word.
"Ouch."
