The Nineteenth Byte

In computer security, arbitrary code execution (ACE) is an attacker's ability to run any commands or code of the attacker's choice on a target machine or in a target process. An arbitrary code execution vulnerability is a security flaw in software or hardware allowing arbitrary code execution. A program that is designed to exploit such a vulnerability is called an arbitrary code execution exploit. The ability to trigger arbitrary code execution over a network (especially via a wide-area network such as the Internet) is often referred to as remote code execution (RCE). == Vulnerability types... ==

PyGamer0

@AaroneousMiller you just needed to give me the full form

Fmbalbuena

WHAT

PyGamer0

@AaroneousMiller actually you found a way to do ACE in an older version of Vyxal?

Redwolf Programs

Doesn't Vyxal have a "run as python" operator?

rues

4:18 PM

Ye

PyGamer0

ok give me any english word and i will give its full form

Aaroneous Miller

@RedwolfPrograms It does, but I believe it has some sort of safety thing to prevent you from wiping the server or whatever

PyGamer0

@AaroneousMiller its disabled on the online interpreter

Redwolf Programs

@AaroneousMiller I'd hope there's some better sandboxing than that lol

rues

@AaroneousMiller It don’t run online do it?

Aaroneous Miller

4:19 PM

@RedwolfPrograms lol nope

pxeger

@PyGamer0 and several in the current version...

Redwolf Programs

But that's less fun :p

hm I wonder why it doesn't work on TIO

i mean clearly it's due to ascii issues but

tjjfvi

It outputs nulls instead of spaces

Aaroneous Miller

@AaroneousMiller That ACEtest file was created in the Vyxal online interpreter

Rɪᴋᴇʀ

4:22 PM

is that just the normal fish quine but wrapped in a loop of of pipes/slashes/underscores/tildes?

PyGamer0

@AaroneousMiller oh wat

tjjfvi

Pretty much

It needs special handling because of the newlines

rues

This is why the interpreter should be client side

Aaroneous Miller

@PyGamer0 I was testing the new ACE exploit I found a couple days ago :)

@rues ye

pxeger

@rues or, use an established-secure sandbox system like ATO ;)

("established", "secure")

rues

4:23 PM

@pxeger too hard

Redwolf Programs

Or use an established and secure one, like RTO :p

rues

Python anywhere free so we use that

PyGamer0

i think i got a tacit system

Redwolf Programs

Locked down docker with runsc is OP

pxeger

ATO's free (for you)...

PyGamer0

4:24 PM

rues

@RedwolfPrograms are you telling ud to run vyxal with rto or is tgere supposed to be a coma there?

Redwolf Programs

Comma

(Not a coma though)

rues

@pxeger Oh cool, are you thinking of adding vyxal?

Comas are important

Redwolf Programs

Vyxal will be part of the 35 that RTO is released with btw

rues

Noice

4:25 PM

@rues I started doing that, actually, and then got distracted and never finished it because I decided the Vyxal online interpreter was good enough

There’s a new one?

Redwolf Programs

4:27 PM

@Fmbalbuena My normal pfp is red

pxeger

@RedwolfPrograms I paid that joke the correct amount of attention the first time

Redwolf Programs

Joke?

rues

😒

Redwolf Programs

@rues Nope, now it's a pawprint in the snow :p

pxeger

@RedwolfPrograms in that it's exactly the same as the halloween one and you've been using it since october?

Fmbalbuena

4:27 PM

/s

rues

Before, it was a paw print in the blood?

Redwolf Programs

@pxeger Yep, but that's not the joke, it's the context for a joke

@rues No, but I know what it'll be in February

rues

Don’t tell me, white again?

Redwolf Programs

Nope, blood

rues

Cool

hyper-neutrino

4:29 PM

the red pfp has more positive associations than negative associations though. red is also associated with love and passion. because you know, color theory

Redwolf Programs

Maybe I'll switch to the Redwolf SMP one :p

rues

@hyper-neutrino hunger too

Redwolf Programs

Oops, that's big

rues

Depends on the shade of red tho

Alan Bagel

@RedwolfPrograms That's the legendary MinePaw

The walls at my school used to look like dried blood, then they repainted them and they look ok now

PyGamer0

i might give this tacit a try

Redwolf Programs

Isn't dried blood mostly brown

Alan Bagel

@rues spooky

rues

@RedwolfPrograms idk

PyGamer0

@RedwolfPrograms reminds me of minecraft grass block

I drink it before that

Redwolf Programs

@PyGamer0 I actually copied the exact colors from it yeah

Redwolf is a minecraft addict

Redwolf Programs

No, it's an Object

Wait how did you go from "Redwolf is minecraft a dict" to "Redwolf is a minecraft addict" lol

rues

Hehe ruined ur joke lmao

@RedwolfPrograms ??? I edited it

Redwolf Programs

No I mean those are like totally different sentences lol

rues

4:34 PM

I started out trying to type “redwolf is minecraft addict”

Idk how addict became a dict tho

My fingers are too fat for this tiny phone

hyper-neutrino

because ur bad at typing

rues

I gud at keyboard typing

I bad at eyesight

I should do nitrotype on my phone to practice actually

Also redwolf and hn, y’all should get back to school or uni or whatever

Redwolf Programs

Nah, I'm in CS right now

rues

Smh my head, y’all always in tnb instead of being productive

Redwolf Programs

@RedwolfPrograms CS as in computer science not tear gas

rues

4:38 PM

I don’t think you needed to clarify that lol

Redwolf Programs

Maybe I'm just in Riot Control 101 :p

rues

Omg are you a cop

Redwolf Programs

Yes you are under arrest for impersonating a TNBer

rues

Wut

You were soliciting illegally golfed code

I have done absolutely nothing wrong

Redwolf Programs

You forgot to ask if I was a cop, I'm legally required to say yes

tjjfvi

4:40 PM

Btw @rues, do you want me to award the bounty in ~3 hours, or in ~5-6 days?

rues

Even my golfed code is so long it barely qualifies as golfed, so it’s all above board

@tjjfvi tge latter

@RedwolfPrograms i asked if you were q cop

hyper-neutrino

@rues i just finished my japanese class earlier and i am "doing homework" for my other class rn

Redwolf Programs

Gay bomb

The "gay bomb" and "halitosis bomb" are formal names for two non-lethal psychochemical weapons that a United States Air Force research laboratory speculated about producing. The theories involve discharging sex pheromones over enemy forces in order to make them sexually attracted to each other. In 1994 the Wright Laboratory in Ohio, a predecessor to today's United States Air Force Research Laboratory, produced a three-page proposal on a variety of possible nonlethal chemical weapons, which was later obtained by the Sunshine Project through a Freedom of Information Act request. == Background... ==

tjjfvi

@rues K. I'll try to remember, but if you could remind me when the deadline is getting close that would be great.

Redwolf Programs

@RedwolfPrograms wtf

rues

4:41 PM

The double quotes make me uneasy

@tjjfvi will do, thanks for the bounty!

Feel free to award it as soon as you want if you’re not sure if you can award it later :)

Redwolf Programs

> It appears that a 'heavy sweating bomb', 'flatulence bomb' and 'halitosis bomb' were also considered by a committee at the time.

> 'flatulence bomb'

rues

@RedwolfPrograms their great plan to defeat the enemy was…to make them fall in love with each other? Wut??

hyper-neutrino

make love not war, as the saying goes

rues

@RedwolfPrograms at that point it’s cheaper to just walk over, fart, and detonate an explosive yourself

@hyper-neutrino they weren’t even guaranteed to fall in love tho

Who approved this lol

Aight time for me to go put splinters in my hand again o/

Hello. who there?

Redwolf Programs

CMQ: Should [0, 0] be truthy or falsy?

I'm thinking truthiness for an array should be based on whether it has any truthy items

Is that a good idea?

Fmbalbuena

@RedwolfPrograms falsy

Redwolf Programs

Should a string of null characters be falsy?

Fmbalbuena

@RedwolfPrograms truthy because the length is 1.

Redwolf Programs

Idk, I'm thinking I should use the same rules for strings

And make null bytes falsy

Or should I just make all non-empty strings truthy

Fmbalbuena

5:13 PM

@RedwolfPrograms true

Redwolf Programs

Should a dict with no data in it ({}) be truthy or falsy?

Fmbalbuena

@RedwolfPrograms Truthy

Redwolf Programs

Wait really?

Why?

Fmbalbuena

Because if the list contains something then it's truthy

Redwolf Programs

Not lists, dicts/maps/objects

With nothing in them

@Fmbalbuena what's your rep level? Are you below the cutoff for 'new user' restriction lifting?

@ThomasWard i have 53 rep

i'd ask a mod to take a look then, or post on Meta.SO about it. Only mods on the site will have an insight to what's up on your account.

Fmbalbuena

My good one is here

Thomas Ward

generally speaking though, your 'question limit' might be a question ban / question posting restriction that you need to ask SO mods about

(TNB is not where SO mods hang out)

Fmbalbuena

yeah

Thomas Ward

6:51 PM

but if it's system imposed you're stuck because not even mods can do anything about it

Fmbalbuena

@ThomasWard main SO chatroom?

@DLosc Your programming language quiz answer got a auto-VLQ flag

@rak1507 those are monads.

@Fmbalbuena or a meta.so post.

i usually try to NOT prod mods on minor inconveniences unless it's an emergency situation

Ok but meta.so is down

7:55 PM

What should converting a number to a dict do?

I'm thinking {n: n}

And what should stringifying a dict do? Not the "fancy" stringify, this is like a "rough" stringify. E.g., arrays are joined by "".

Should I just sort the dict's items by their keys and join by ""?

That could actually be useful for golfing some stuff

Alan Bagel

@RedwolfPrograms Number to dict should be {1: 1, 2: 2, 3: 3, ..., n: n}

Redwolf Programs

Thing is, that would be inconsistent with my handling for arrays, which is just [n]

If it was [1, 2, ..., n - 1, n], I'd do that

Fmbalbuena

CMQ: why This is cursed

Redwolf Programs

Try not to ping random users when you have a question that isn't directly relevant to them

Fmbalbuena

@RedwolfPrograms ok so you can fix?

Redwolf Programs

I can't go to TIO from my school's wifi, sorry

Fmbalbuena

@RedwolfPrograms oh ok

code is print((lambda: __import__("sys").stdout.write('Hello, World!'))())

and prints Hello, World!13

DLosc

What did you expect it to do?

Fmbalbuena

8:23 PM

printing inside lambda function

i'm trying to do one-liner

DLosc

Why not just use print in the lambda function?

Fmbalbuena

@DLosc oh sorry i'm trying to do but won't work

@DLosc Try it online!

ok so the hard part is while loops.

hyper-neutrino

i don't understand what you are trying to do

DLosc

I'm really confused about what you're trying to do here... (ninja'd)

hyper-neutrino

why can't you just print normally

Fmbalbuena

8:25 PM

@hyper-neutrino `print inside lambda function

hyper-neutrino

that still doesn't explain anything

lambda x:print(x) ??

lambda:print("Hello, World!")

Fmbalbuena

@hyper-neutrino but without newlines

Rɪᴋᴇʀ

python doesn't allow while loops inside lambdas

hyper-neutrino

lambda x:print(x, end = "") ?

lambda x:print(end = str(x)) ?

Rɪᴋᴇʀ

for loops can be done via list comprehension but not while loops

Fmbalbuena

8:26 PM

@Rɪᴋᴇʀ yeah but i'm trying to do

Rɪᴋᴇʀ

it is not possible to recreate one

hyper-neutrino

while loops can only be sort of simulated using recursion in some cases but you can't do real while loops and you're better off either using comprehension or just programming normally

Rɪᴋᴇʀ

python (3 at least) doesn't let you readjust the iterator variable in the loop like some langs so

rues

You could use eval if that counts

Rɪᴋᴇʀ

eval never counts :/ lmao

Fmbalbuena

8:27 PM

@hyper-neutrino or better itertools

Rɪᴋᴇʀ

itertools and abusing lambdas should not be included at hte same time

Redwolf Programs

Do Python's array comprehensions work with generator functions?

(If Python has those)

@RedwolfPrograms yes

?

@RedwolfPrograms yes

8:30 PM

@RedwolfPrograms I think so, if I understand what you mean

Rɪᴋᴇʀ

pretty sure that errors if it attempts to loop forever

i remember trying it once

Redwolf Programs

Oh

hyper-neutrino

yeah using eval for oneliners is 100% cheating cuz like

otherwise there's no point

Fmbalbuena

stop talking

Rɪᴋᴇʀ

???

Fmbalbuena

8:30 PM

because i'm trying to do

Redwolf Programs

I know with JS you can use generators in for..of loops (the closest thing to array comprehensions other than .map) to make infinite loops, but generators are really weird in JS and so are for loops lol

Though you can just do for (var x of arr) arr.push(1); in JS lol

Rɪᴋᴇʀ

huh. apparently generators work in python2 and 3 both

DLosc

@Rɪᴋᴇʀ I don't think it errors, it just loops forever

Fmbalbuena

@Rɪᴋᴇʀ I can. i can do infinite loop using lambda

Try it online!

Redwolf Programs

Wish I could use TIO, I feel like I'm missing out lol

TIL about the "Firing Squad" Synchronisation Problem

Firing squad synchronization problem

The firing squad synchronization problem is a problem in computer science and cellular automata in which the goal is to design a cellular automaton that, starting with a single active cell, eventually reaches a state in which all cells are simultaneously active. It was first proposed by John Myhill in 1957 and published (with a solution by John McCarthy and Marvin Minsky) in 1962 by Edward Moore. == Problem statement == The name of the problem comes from an analogy with real-world firing squads: the goal is to design a system of rules according to which an officer can command an execution detail...
