I did some research to solve the AMD vulnerability debate from earlier: there were two attacks specified in the paper: Spectre and Meltdown. Spectre affects basically every CPU; however, only Intel chips seem to be vulnerable to privilege-escalation attacks via Spectre. It's theoretically possible to do a privilege-escalation attack via Spectre on an AMD chip, but it would be much, much harder, and likely involve exploiting some other vulnerability. Meltdown only affects Intel chips since 1995.

Oh, something I forgot to add to that blob of info: Meltdown is the one that will incur the performance penalty. Spectre is fixable by compiler and library maintainers, while kernels need patching for Meltdown.

@ASCII-only Right, because not all rules are TC. How about as many as possible?

@Mego How I understood it is that you can't stop Spectre without making new CPUs, detecting attacks is almost impossible, and you can really only make using the infoleak harder

Anonymous

@mınxomaτ I think that PEs are assumed to be possible because of the possibility of reading the root password via Spectre

I was playing a board game called "Sentinels of the Multiverse" recently. It's modeled after a bunch of fictional comic books, so every card in the game has a "quote" from one of the comic books. In one of the quotes, the character says something about analyzing where a bullet went, and says "The wind is going 6 knots per hour"

6 knots per hour.

That was painful to read

Honestly still hurts a little bit

But the bigger problem is that Knots per hour is speed/time, which would be acceleration.

The wind is travelling at 9.2 Meters per second squared!

@H.PWiz Well you can't put two lines in a here-string right?

H.PWiz

Oh, didn't pay attention to the newlines. You ca use '..' though

Pavel

Mm, I suppose. Still, a herestring should succeed too, right? It's the same thing.

H.PWiz

Yeah, no difference

@cairdcoinheringaahing Explain?

Wheat Wizard

@cairdcoinheringaahing Is there an explanation on how it works somewhere? The wiki doesn't exist

DJMcMayhem

The city I live in just announced that it's going to start providing municipal, gigabit, net-neutral internet service. :)

caird coinheringaahing

I'm working on it, hold on

DJMcMayhem

That's really exciting

Pavel

@DJMcMayhem Nice. What city?

How it works (cc @DJMcMayhem @WheatWizard)

DJMcMayhem

Binary hexdump:

00000000: 11100001 10010101 10010101 11100000 10101010 10101010  ......
00000006: 11010101 10010101 11001010 10101010 11000101 10010101  ......
0000000c: 11000010 10101010 01010101 00101010 00010101 00001101  ..U*..
00000012: 00001010 00000101 00000010 00001101 00001010           .....

I still fail to see the pattern

caird coinheringaahing

¯\_(ツ)_/¯ Maybe it's broken

Pavel

What's the pattern supposed to be?

caird coinheringaahing

I think you may have an incorrect hexdump

DJMcMayhem

Me?

If mine is wrong, then pavel's is wrong

caird coinheringaahing

21:01

Yeah. This is the binary of each character

DJMcMayhem

AH

caird coinheringaahing

?

DJMcMayhem

@cairdcoinheringaahing Ah, It makes sense now

caird coinheringaahing

Care to share?

DJMcMayhem

@cairdcoinheringaahing You don't understand what I'm saying. I meant "Ah, thanks @cairdcoinheringaahing for explaining what the binary of every character is. Now I understand the CMC better."

@cairdcoinheringaahing SOGL, 13 bytes: '⁰Δ№{Ƨ10m2│ζo

caird coinheringaahing

AH, now I understand :P

DJMcMayhem

Python, 63 bytes: print(''.join(chr(int(("10"*7)[:i],2))for i in range(14,1,-1)))

I know just printing it straight up is shorter

caird coinheringaahing

10 bytes in Jelly (which is shorter than the string) :P

dzaima

I'd have ~11 bytes in Canvas, but at least 3 features are missing (one of them being the ability to push numbers > 9 ಠ_ಠ)

wizzwizz4

@dzaima What are the other two?

DJMcMayhem

21:18

@cairdcoinheringaahing 52 bytes in brain-flak: ((()()()){}()){({}<(({})({})())((({})){})>[()])}{}{}

Brain-flak is shorter than python kek

caird coinheringaahing

@DJMcMayhem Nice :P

@DJMcMayhem I got 35 bytes in Python. Sorry :/ (I know what you mean though)

dzaima

@wizzwizz4 ［ needs to be for each prefix and there are no base convertion built-ins

DJMcMayhem

:/

@cairdcoinheringaahing Addendum: Generating it in brain-flak is shorter than generating it in python.

betseg

@cairdcoinheringaahing did you see my brainfuck answer to your cmc

Pavel

@cairdcoinheringaahing It was not stated that a trailing newline is not allowed, and the default is that it is.

caird coinheringaahing

21:22

@betseg The _ CMC? Yes, why?

betseg

just wondered

caird coinheringaahing

@cairdcoinheringaahing Jelly, 9 bytes: ⁽×ŻB¹ƤḄUỌ

dzaima

heh, who'd've thought that the docs stuff for Canvas would be over half the size of the code

Pavel

> Q: Doesn't rawhide eat babies / kill pets / burn down houses / break constantly?
> A: No. Please stop telling everyone that.

betseg

plot twist: it does

Pavel

21:29

Can't tell if joke or if you've used Rawhide

mudkip201

21:42

yay for misreading a question and doing more work than needed

Pavel

@WheatWizard Out of curiosity, are you actually going to try to do that, or was that a joke? 'cause it took a week before I got an answer in a real programming language.

Wheat Wizard

I tried it, but probably not, I'm on winter break so I'm pretty lazy right now

I need some real work that I can get distracted from before I can do anything like that

Pavel

Yeah, I'm the same way. I can only work on hobby-type-things when I have more important things to do.

Apparently our school now blocks github and github.io, except my github.io page

I swear people only look at the test cases on challenges, and not rules about input formats

Wheat Wizard

that's why I don't like test cases

Anonymous

Both answers currently on the RFC 2550 challenge use the same input format as the test cases, even though they would both greatly benefit from using a different allowed format

Riker

@Zacharý why though

Zacharý

Because for the joke of a CS class, I submitted a project via github (at least I think that's why, but my partner's is still blocked)
