programming

[brazen eagle]

Sneaky

Good way to divide by 2

Shift right, and 1

The add four times is doing a shift left by 2

It's not wrong

And this is why premature optimization is bad and you shouldn't do it

The compiler is smarter than you

I should look at how Java does this in bytecode

So I can yell at people to stop trying to optimize code and make the thing readable

[wheat forge]

lol

yeah agreed

people shouldn't try optimising something unless they know for sure it'll be slow, and have tested it

I was doing a thing not so long ago where I was trying to optimise some C, spent ages on this one section, then realised it was barely ever called and by focusing on another bit it knocked a lot of time off

[brazen eagle]

I mean if you have a 50 kHz cpu and 16K memory then by all means optimize

[wheat forge]

not saying you shouldn't optimise code, but you shouldn't blindly 'optimise' code that may or may not even be the problem

[brazen eagle]

Even then it'll probably end up worse than before with the added bonus of being unreadable now

People often try to be too clever. I would know I was one of those

[wheat forge]

yeah

[lilac holly]

To write a program that can delete all my files in my downloads linux files should I write this in python? And where do i begin

[wheat forge]

why would you do that when you can use rm?

[brazen eagle]

rm -rf /home/name/Downloads/*

[wheat forge]

^

[brazen eagle]

In python: system('rm -rf /home/name/Downloads/*')

Or something

[lilac holly]

I want to write my own programs

[stone kayak]

not in python, pretty sure I saw someone benchmark it but tbh the python interpreter dues like no optimisation so what can you expect

no I did not :-(

[onyx merlin]

I think we did like ((x<<1)+2)>>1

[brazen eagle]

I mean in JavaScript you'd do npm install isOdd

[brazen eagle]

Eww

I mean it work but that's just dumb

[onyx merlin]

That was... the whole point

[brazen eagle]

Coding test?

[onyx merlin]

No

I have a great write-up on a problem involving bitwise operators on my binarysearch account

[brazen eagle]

Oh I see

You can try to do it by overflowing the buffer...

Or underflowing those are fun too

I am trying to make a DIY Wifi Pineapple using OpenWRT and in a captive portal I'm trying to log the captured creds into a file

But am stuck with PHP

I'm following this guide :
https://www.smeegesec.com/2017/03/captive-portal-wifi-phishing-with.html?m=1

Any idea how to log them ?

[tribal smelt]

but there's a php script there @brazen flax

[brazen flax]

I tried the one given which saves the credentials, but it doesn't seem to work

[tribal smelt]

did you have stored.txt in the directory?

[brazen flax]

Yes. I have tried :
-> creating the file
-> not creating the file
-> change perms
-> other fixes

None helped

[tribal smelt]

you can dm me if you'd like.

@brazen flax Does the modified date / time of the file change when the script is ran?

And does the file actually get fwrite($file, "Username: " . $username . "\n" . "Password: " . $password . "\n\n"); in it?

[stone kayak]

@onyx merlin this is my wacky bitwise operator writeup https://binarysearch.com/problems/Check-Power-of-Two/editorials/3057426

[onyx merlin]

It wouldn't let me look so ok

[onyx merlin]

bee you're mad

[stone kayak]

I probably can't do that today but I was specifically studying bitwise operators when I wrote that 🤣

[wheat forge]

it's a pretty obvious solution really

from the definition of a power of two

if you want to go full bitwise n-1 is ~-n

is there any way to submit a solution to that site without having to sign up

[brazen flax]

I'll have a look at this.

[tribal smelt]

@brazen flax I'd check to see if anything is even being put in the file as well

[lilac holly]

im starting to learn javascript, i might learn more tonight.

[sour apex]

i'm trying to write a loop to go through a website rabbit hole in bash, how do i declare the response returned as the next request and do it recursively?

should i switch to python?

[brazen eagle]

might not be a bad idea

are they using redirects, or links?

[sour apex]

no redirects. the get request for the next request is in the response of the current request

[brazen eagle]

in plaintext?

[sour apex]

yes

[brazen eagle]

might as well use netcat then...

[lilac holly]

im really bad to hack but can this server help me get bedder

[mystic nimbus]

@brazen eagle in your great escape python script, why not just put the ip in the request line instead of defining it as a variable

[true pumice]

Easier to change for people viewing the script.

[brazen eagle]

I could

it's a quick and dirty script

[mystic nimbus]

I just usually never had separated like that and was wondering

[true pumice]

I always define it separately, especially if I am going to use the host more than once, allows me to just reference the variable as opposed to getting the user to change a bunch of values.

[mystic nimbus]

I have had a few scripts in the past where I could have done something similar, learn something new everyday on THM

[brazen eagle]

I could have added it as a cli param

but since I was reusing the script a few times, I didn't feel like retyping the ip each time

I set the target ip as an env var when doing THM boxes as well, makes writeups a bit easier

[lilac holly]

Anyone have any recommendations on where to learn c++ practically?

[lilac holly]

how do i access a link using an proxy

like when i do requests.get(url), i dont want to reveal my ip

i wanna access using a proxy

[onyx merlin]

Why don't you want to reveal your IP? @lilac holly

[lilac holly]

am making my own prototype vpn

if that makes sense lel

[onyx merlin]

No it doesn't

Don't roll your own crypto.

[lilac holly]

someone people told me python is not the best for this tho

[lilac holly]

?

i heard free vpns sell ur data, paid ones are paid

[onyx merlin]

You don't need a VPN usually.

[surreal bronze]

The real question is

Why do you want to use a VPN

[brazen eagle]

They are probably correct. But also don't roll your own crypto

As for proxy settings, they should be documented

[lilac holly]

ok

[lilac holly]

socket.gaierror: [Errno 8] nodename nor servname provided, or not known

[clever loom]

hey guys im new to programming and i was wondering if it was something i could do and would it be really hard to start hacking to someone new like me

[hexed flax]

of course it's something you could do if you keep practicing!

just like everything

[clever loom]

cause it looks very hard

[onyx merlin]

Programming and hacking are somewhat related, but not the same.

[brazen eagle]

I wouldn't say it's easy, but it's managable

[clever loom]

ok

what do u guys create

[surreal bronze]

What do you want to create?

[clever loom]

like what is something u guys create?

[sharp coral]

if you do something repetitively on the computer often then it's worth trying to automate it through a program

I've made a wrapper for nmap because I dont feel like finding ports and having to re-scan in stages and also keep typing in those commands all the time so I made a script to feed it an IP and let it rip, thats a really basic example but the best way to learn is by picking a project and kinda figuring it out as you go along

APIs can give you a lot of fun projects too if you get some dev creds

[clever loom]

ok

[brazen eagle]

I just use RustScan...

but I should go a bit further and automate the scripty bits

[surreal bronze]

RustScan is good but it's way more satisfying creating your own 😉

[brazen eagle]

sure

[true pumice]

Imo, unless it can be improved upon its a waste of time and energy.

Also depends on what task you’re trying to complete.

[dapper reef]

Hello guys, I need some advice/source if possible.
Im having a really harsh relationship with algorithms.
What is "the best" way to learn algorithms. I tried LeetCode, CodeWars, etc.. but not much improvement.
How you guys learned algorithms, how to have a deeper understanding of it?

[magic falcon]

Are you talking about understanding algorithm complexity?

[brazen flax]

Any Archlab users here ?

[surreal bronze]

Depends, its great practice 🤷‍♂️

[true pumice]

Not always, if you know another useful tool that could be created, it would be much better to put all that energy into the other tool.

My fave Python operator, the spaceship

Turn floor division into ceiling division by putting it into a spaceship

[onyx merlin]

Care to explain?

[stone kayak]

It's not actually an operator it's just abuse of mathematics:

--0-- 12 // 5
(-(-0)) - ((-12) // 5)
-(-12 // 5)

TL;DR it works in negatives (turns the world upside down) so the "floor" actually becomes the ceiling. We use abstraction because --0-- looks way funkier and funnier

https://bugs.python.org/issue43255#msg387248

[onyx merlin]

I swear "it's just abuse of mathematics" is your MO at this point

[wheat forge]

I prefer the 'goes to' operator

[onyx merlin]

Slides to.

[solar wave]

Put under MongoDB "pain in the ass to use with Django"

Django needs every model to correspond to a database row -> Mongo supports embedded documents that don't need to contain an ID -> the models have to be set to abstract to get around it -> djongo doesn't let you serialize abstract models and the documentation is utter trash

[brazen eagle]

use a bash script?

[lilac holly]

No sir @brazen eagle

I'm familiar with Python ?

why not use bash

right tool for the job

[hexed flax]

learning bash and writing the script will probably take you less time than doing it in Python

[lilac holly]

Thank you for the insight!!

[glass grove]

is there any way i can encrypt some text using a passphrase in python and then decrypt the text with the same passphrase in javascript

pretty much, i want symmetrical encryption. it doesnt have to be cia security, but just encrypted.

[tulip sail]

@glass grove Both those languages will have implementations of a bunch of symmetrical encryption algorithms -- those will be compatible with each other

So yes

[glass grove]

ive been googling around and re-discovered aes. but im super confused how i can get it working on both languages together...

[tulip sail]

Well, look at each of the implementations for it. There'll be a Python implementation and a JS implementation

Break it into two separate parts

https://dev.to/halan/4-ways-of-symmetric-cryptography-and-javascript-how-to-aes-with-javascript-3o1b

https://www.novixys.com/blog/using-aes-encryption-decryption-python-pycrypto/

[glass grove]

mhm

[tulip sail]

No idea if those are any good, but first result on Google

[glass grove]

thanks, ive looked at those already, but ill reread

[brazen eagle]

use AES

don't try to roll your own

there should be reference implementations lying around

probably in the python crypto libraries

I think JS might have a crypto lib as well somewhere

if it's not already baked into the language

[glass grove]

im dont think ill be reinventing the wheel haha. im just having some trouble understanding aes

[brazen eagle]

plaintext + key goes in, magic happens, ciphertext comes out

[glass grove]

yeh, i thought it was that easy

how naive i was 😅

theres like different modes and initialization vectors ugh

[brazen eagle]

https://www.w3.org/TR/WebCryptoAPI/#crypto-interface

ah

don't use ECB mode

that's crackable if you know some plaintext

an IV is generally a nonce

[glass grove]

mhm

[brazen eagle]

CBC is generally fine

GCM is probably better

[glass grove]

alri

[brazen eagle]

https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto

might help for the JS side

https://pypi.org/project/pycrypto/ might be helpful for the python side

[tulip sail]

pycrypto is outdated, I believe

[brazen eagle]

ah

[tulip sail]

pycryptodome is the replacement iirc?

[brazen eagle]

first hit on google

https://pycryptodome.readthedocs.io/en/latest/src/cipher/cipher.html this thing?

just make sure both ends can handle the same modes

yeah ok the IV seems to be stored in the file itself

in the example

[glass grove]

alright thanks guys!

[glass grove]

pycryptodome recommends MODE_EAX. would u agree

[glass grove]

@tulip sail @brazen eagle i think i got it, thanks for the help!

int main() {

cin >> arr[i];
for (int i = n - 1; i >= 0; i--)
cout << arr[i] << ' ';
return 0;
}

anyone know why this isnt running in visual studio?

its underlining the n in int arr[n], and idk why

[rain ermine]

Did you try it on Linux?

I don't see any errors

[exotic skiff]

nahh im running it on windows

I might honestly just do my competitive programming stuff on my Vms

[violet ermine]

@exotic skiff providing the compilation error would help in deducing the problem, visual studio can definitely be tricky for beginners

[outer jewel]

Pretty sure that n needs to be a compile time constant for stack based arrays?

If you want to create an array of size n basen on input you need to use the heap, google for the new keyword, and remember to delete

[violet ermine]

@outer jewel oh good eye, another easy solution could be std::vector

[azure relic]

underlining is likely cause n hasn't been given an explicit value yet (int n = x, etc)

Is there a file for Hugo which specifies which Hugo version to build the website with?

Like package.json for Gatsby?

If you're looking to set a specific version of a framework your Cloudflare Pages project is using, note that Pages will respect your package manager of choice during your build process. For instance, if you use Gatsby.js, your package.json should indicate a version of the gatsby NPM package, which will be installed using npm install as your project builds on Cloudflare Pages.

Has anyone here developed a CyberChef module before? I’ve never developed in node.js and some mentorship would be hugely appreciated 🙌🏼

[dim slate]

Can anyone explain to me, why, in C does int have 2 possible memory allocation values. Int can be either 16 or 32 bit but I can't find out what decides which it should actually be and why?
Sorry if this is worded badly.

[magic falcon]

Can you provide a bit of context about what you're asking? In an absolute sense memory is allocated based on architecture based word size.

[dim slate]

OK, so i have a small program, which simply uses sizeof(Data_type) * 8 to return the size of a data type in C in bits. I wrote and compiled this program on 64x windows, using a Borland C/C++ compiler (bcc32) which i believe is 32x.
When comparing sizeof(int) and sizeof(long int) both return a size of 32 bits, the program also returns the range of the variable and obviously, the ranges match given that both are the same bit size. When i refer to documentation for C, long int has a size of 32bits but int can either be 16 or 32 bits. So what goes into consideration when C is determining how much memory to allocate to an int variable. Will an int always allocate to 32 bits on a 64x system and 16 bits on a 32x system (I think this is what your reply is mentioning but i'm not sure).

[magic falcon]

The compiler decided in each case - Wikipedia has a pretty good article on C data types, and should be used as a base to expand out from.
Sometimes, though, compilers will do weird stuff and do something like what you are talking about - usually it's because the programmer is doing something funky that results in the C standard being not defined for that case, or maybe the compiler isn't very well modernized. Either way, the C standard clearly defines what the size is, and it is all on the compiler to allocate 2B for short int int and [un]signed int.

What’s your questions?

[lilac holly]

i use colour scheme has the name "morning" but it has a problem with the colour

@true pumice you see the "0" has a white highlight and I don't know how to turn off it

[vernal vigil]

It looks good

[lilac holly]

😫

[true pumice]

Sorry I forgot to respond hah. I have no clue, I don't know anyone who does or use that colour scheme.

[lilac holly]

thanks you i'll change to another one

[vernal vigil]

My only question is, why are you on light theme

[solar hull]

My problem with that is odd kerning.

[lilac holly]

I just bored at dark theme and want to change a little bit

I change them regularly

[tulip sail]

What on Earth are you talking about?

[lilac holly]

about the theme color of MacVim

😫

[exotic skiff]

HAHAHA NO, I WAS DOING THIS ONLINE TEST AND IT SAID THAT I GOT ONE WRONG BUT IT DIDNT TELL ME WHICH ONE

it was this multiple choice thing

I asked cause that was the only question I wasnt sure of

its just for fun hah

haha*

[surreal bronze]

ok then

[lilac holly]

In order to write a simple program that runs this command --> sudo openvpn Downloads/rokie.ovpn ; will I need to write this in bash or will python suffice?

[onyx merlin]

God don't do that in python

Python is crazy overkill

Just add it as a bash alias or something

[lilac holly]

Ok bash it is lol

[surreal bronze]

Yeah no don't do it in python

[lilac holly]

#! /bin/bash/roki xD

[dull tangle]

add something likealias thmvpn='sudo openvpn /home/< USER >/Downloads/rokie.ovpn to ~/.bashrc and then do source .bashrc then everytime you run thmvpn you will be prompted with your password to run the ovpn command 🙂

[lilac holly]

freaking dope! thanks man xD

Let's see if i get this right

[dull tangle]

You should see in bashrc where the alias are roughly and just add your own in 🙂

[surreal bronze]

You could also set it up to do Muir's VPN script

[lilac holly]

so i would need to nano ~/bashrc to do this right?

[surreal bronze]

Yup

[dull tangle]

Yea

[tulip sail]

I'd do it with this myself:

alias thmvpn="tmux new -s THMVPN  \"sudo openvpn ~/Downloads/MuirlandOracle-THM.ovpn \""

[dull tangle]

Depends if you use tmux I guess

[tulip sail]

Keeps it nicely backgrounded, means it survives virtually everything short of a reboot, and means you can't have two open at once

Oh, I'd just immediately background the session and leave it there 🤷‍♂️
No actual Tmux use required

And it tends to be cleaner shoving it in .bash_aliases rather than directly in .bashrc, but whichever

As long as the .bash_aliases file is sourced in .bashrc, which it should be by default for most distros

[lilac holly]

I ran the command you gave @tulip sail and it seems to exit me out

[tulip sail]

Exit you out?

[sharp coral]

did you change the filename

[lilac holly]

here's a screen shot

oops

no i did not

[tulip sail]

Funnily enough, you don't have a file called ~/Downloads/MuirlandOracle-THM.ovpn

That bit needs changed

[lilac holly]

i am an idiot

[tulip sail]

Nah -- happens to everyone 😄

[lilac holly]

Still having the same problem lol

I don't think it affects that much. It's just 1 point ;-;

[solar dust]

How would a music player be for someone starting out?

As a project.

My b

[onyx merlin]

Yeah, because homework questions

[lilac holly]

not even this?

[tepid cargo]

let me see a little wait

[lilac holly]

Thanks

[tepid cargo]

so in the side1 and side 2 part..

did u set a grid-row?

cause the side1 is taking 100% height of the container which it should

maybe make all the intro article, main article grid-row of 2 and and make the side grid-row of 1

and then in the bottom it should automatically align

https://www.w3schools.com/cssref/tryit.asp?filename=trycss_grid-row

probably check this out

[lilac holly]

yep, I set grid-template-rows to custom sizes.

I'm not really allowed to change the html part. I can only mess with grids on the footer i.e the gray areas below.

[tepid cargo]

u don't have to change the html part

just use a specific selector

or add a class

ezpz

[lilac holly]

Ohhhhh

it works now. thanks

[surreal bronze]

Wdym?

[solar dust]

As a project to create.

A simplistic one with a UI.

[cursive orchid]

@solar dust well it will boil down to audio tags in html, you can view this page to see more: https://www.w3schools.com/html/html5_audio.asp
but essentially you're going to want to store the audio files (up to you how you handle that)
and then render each one within an audio block
so in pseudocode, something like

<audio controls>
  ForEach song in songs: <source src="song.link" type="audio/mpeg" />
</audio>

[solar dust]

So, it will boil down to finding a way to auto-detect audio files in a user's file directory?

[tepid cargo]

cool np

[cursive orchid]

yeah, so different languages will have different ways to find that

for example in node you could use the fs module to read the user's directory

[magic falcon]

it's less auto-detecting and more adding a source path to find files in. Autodetecting would be continuous scanning, which you aren't going to want to do for a variety of reasons

[cursive orchid]

^

[tepid cargo]

one of my first project was a sonic visualizer in flash

🤣 actionscript ftw

[lilac holly]

Hey @tulip sail, sorry to bug. The command you suggested seems to reset every time i power down my machine. Is there a syntax to make it persistent ?

[solar dust]

I'm guessing it's a matter of a command to prompt open the file directory to choose anything in a .mp3 format.

[lilac holly]

So convert it from .sh to .mp3?

[onyx merlin]

Excuse me, what?

[tulip sail]

Stick it in your bash aliases

[lilac holly]

Okay let me work this out

So I copy and paste here correct ?

[onyx merlin]

No . After it.

[lilac holly]

It's not letting me. Not too familiar with vim

[onyx merlin]

Your filename looks wrong. That's what I'm saying.

You have a random .

[lilac holly]

Wait, you mean this bottom part of my syntax ?

Stop using control z

[lilac holly]

I switched it from aliases to thmvpn

[onyx merlin]

It does not close the program. It backgrounds it.

[lilac holly]

okay /:

[onyx merlin]

There was a reason the file was called that.

[lilac holly]

because it's my actual rokie.ovpn file right ?

I'm so confused

[onyx merlin]

Eh I'm out

[clear needle]

just ask your question

[sly lake]

What does this regex do?
const escapeRegex = str => str.replace(/[.*+?^${}()|[\]\\]/g, '\\$&');

[brazen eagle]

good tool I use to understand regexes

[wispy tusk]

I want to make a worm which will automatically be able to replicate and try to pivot itself across the other devices in same private network in which the victim pc is connected. The worm will also contain a reverse-shell payload and send me a shell from all the computers it has successfully pivoted to. Also the worm needs to be executed only once and it will automatically execute the next worm in the daisychain.. It will also create cronjobs/services which will be run at boot to maintain the access. How do I achieve this? I want to use python for coding it. Any good resources/references which can be helpful?

[tulip sail]

@wispy tusk Do I want to know why?

[wispy tusk]

I love making challenging tools which will help me learn a lot along the way.

[tulip sail]

That's illegal in enough places (to develop, not deploy), that I'm gonna say please don't ask here for it. Not a warning as much as a request there 😄

I can see where you're coming from with an educational perspective though, so if you do try it, keep it safe in a VM network and don't deploy it elsewhere

[wispy tusk]

Ooh...😅😅 okay..no issues😅

[wispy tusk]

Can Making it open-source for educational purpose be safe?

[tulip sail]

I personally would suggest against it, purely because there aren't many legitimate uses for other people to use it. I can see why coding it would help educationally, but chances are people will deploy it if you make it open-source.

Equally, it's outright illegal to develop that kind of thing, dependent on where you live. If you're in the UK then I would strongly suggest against it

[wispy tusk]

Ahhh... Alright.

[ebon jackal]

idk Im being pixel perfect and still getting inconsistent positions

Im using a 19.2x10.8 graph

placing the points where I want them to be

then just multiplying their positions by 100 and adding those values to the points in my code

but its really not pretty and idk why

[ebon jackal]

ooooo I think I found it out

:D

[brazen eagle]

aliasing?

[ebon jackal]

nah I still dont know lol

I tried my best I cant get it to be pretty

My program relies on Hashcat, how can I get Hashcat in CI? How can I test the Hashcat module works in CI? 😛

[steady anchor]

import os
os.system("hashcat")

sry

i am just sad they killed yahoo api

[brazen eagle]

Is there a hashcat docker image?

https://hub.docker.com/r/dizcza/docker-hashcat/

[pine apex]

I would create a custom docker image that has all the tools you need to build and test your project. In your CI step you can just pull this image and start building/testing, without having to install tooling first, which can save quit a bit of time

[magic falcon]

typically each step in a CI/CD pipeline runs in it a separate container, with outputs at each stage injected into a shared storage volume or into the next image build

[sly breach]

yess there's defo a CUDA & OpenCL image(s) (:

Or at the least when I last pulled ~4-6 months ago I might have to fact check

you're largely limited by the gen of CPU (i.e. if it's cloud based) which is where I had most of the issue getting the correct SDK's for but

if you're asking about cloud lemme know what provider & tier and I can probably point you in the right direction in terms of all of the above :^ I'm v sure I still have intel SDK's that were and absolute pain to obtain

plus IIRC you can just -d "string here" "dict/ruleset" and you're a given

[hollow bison]

anybody here know c++

quiet confusing why isn't this simple loop grow

i thought the array will have every single value of i

debugger didn't detect it

[solar hull]

I think the debugger only shows the value at *test, that is test[0]

[brazen eagle]

that

try evaluating test[4]

[surreal bronze]

import time
start = time.time()

while function is running:
    print(f"{time.time() - start}", end="\r")

How would It time a function but print what the current time is

import time
import functools

def timer(f):
  @functools.wraps(f)
  def wrapper_timer(*args, **kwargs):
    start = time.time()
    result = f(*args, **kwargs)
    print(f'Time taken: {time.time() - start}')
    return result
  return wrapper_timer

@timer
def get_result():
    time.sleep(10)
    print("Done")

get_result()

This works, but it only prints the time at the end...I want it to continually be printing how long it takes (like above) while the function is running

[true pumice]

I’m unsure what you mean?

[surreal bronze]

Might need to do threading

hmm okay,

while True:
    print(f"{time.time() - start}", end="\r")

If you run this, it will act like a stopwatch and keep on printing the time elapsed since you started the program

I want it to do this, while a function is running

[true pumice]

You want it to continually count up while the program is running?

[surreal bronze]

exactly,

but it has to keep printing the time elapsed since the program / func is running

[true pumice]

Give me a moment to clean up

[surreal bronze]

kk

https://stackoverflow.com/questions/5316284/python-run-one-function-until-another-function-finishes

Something like this

Im kinda there

nvm.

[surreal bronze]

okay

import threading 
import ctypes 
import time 
   
class thread_with_exception(threading.Thread): 
    def __init__(self, name): 
        threading.Thread.__init__(self) 
        self.name = name 
              
    def run(self): 
  
        # target function of the thread class 
        try: 
            start = time.time()
            while True:
                print(f"{time.time() - start}", end="\r")
        finally: 
            print('ended') 
           
    def get_id(self): 
        if hasattr(self, '_thread_id'): 
            return self._thread_id 
        for id, thread in threading._active.items(): 
            if thread is self: 
                return id
   
    def raise_exception(self): 
        thread_id = self.get_id() 
        res = ctypes.pythonapi.PyThreadState_SetAsyncExc(thread_id, 
              ctypes.py_object(SystemExit)) 
        if res > 1: 
            ctypes.pythonapi.PyThreadState_SetAsyncExc(thread_id, 0) 
            print('Exception raise failure') 

def start_timer():
    t1 = thread_with_exception('Thread 1') 
    t1.start()
    time.sleep(5)
    t1.raise_exception() 

start_timer()

So turns out you cant force kill a thread, you have to have the thread "fail" / raise exception

its messy but it works

[true pumice]

Okay, I am back at my PC.

[surreal bronze]

Ah nice, I sorted it but if you can find any other way (without using global) that would be amazing 😄

its quite a fun challenge to

@true pumice

[true pumice]

Are you entirely set on threading?

[surreal bronze]

I couldn't think of any other way

Yes you could use global without threading

from time import time, sleep
from _thread import start_new_thread

def long_function():
    global finished
    sleep(20.5)
    finished = True

def time_function(func):
    global finished
    finished = False
    start = time()
    thread = start_new_thread(long_function, ())
    while finished != True:
        sleep(1)
        current = time()
        print('Time Elapsed: ' + str(current - start))
    end = time()
    print('Finished after: ' + str(end - start))

time_function(long_function)

Something like that would work without threading

but it uses global which I would rather not do

[true pumice]

@surreal bronze This is a sloppy way of using asyncio in python. It seems to do the job.

import asyncio, time

async def func(delay, what):
    await asyncio.sleep(delay)
    print(what)

async def main():
    start = time.time()
    
    task = asyncio.create_task(
        func(10, 'hello'))

    while True:
        if task.done():
           break

        else:
            print(time.strftime("%H:%M:%S", time.gmtime(time.time()-start)))
            
        await asyncio.sleep(1)

        
asyncio.run(main())

[brazen eagle]

probably an existing lib

[true pumice]

Technically there is, time works perfectly fine. Jayy wants it to continually output how long the program was been running for which is a little hard to do without threading or concurrency etc.

[brazen eagle]

Ah ok

I used tdqm to make a progress bar thingy recently but you want a spinner, basically ye?

[true pumice]

I looked into using a spinner, I used one when I originally got into threading but some of the code was outdated so I scrapped it 😁

ooh this is pretty neat https://github.com/pavdmyt/yaspin

[true pumice]

I try to stay with base libraries if I can.

It works with powershell

Not cmd

[true pumice]

@balmy flint So you want two lists, one of which is immutable and the other that is modified?

[balmy flint]

Yes both are same and if one is modified it won't affect the other

[true pumice]

Is the program small enough to be shared here?

[balmy flint]

To me ?

[true pumice]

This is the first way that came to mind.

def list_duplicator(list):
    return [item for item in list]

A = [1,2,3]

B = list_duplicator(A)

print("List A:", A)
print("List B:", B)
print("\nRemoving an item from List A")
A.pop()
print("List A:", A)
print("List B:", B)

Output:

List A: [1, 2, 3]
List B: [1, 2, 3]

Removing an item from List A
List A: [1, 2]
List B: [1, 2, 3]

Using a function that returns the values using list comprehension means that you can continually re-use the function to do this for multiple lists. @balmy flint

[balmy flint]

Actually this isn't working for me sadly

[true pumice]

What version of Python?

[balmy flint]

Well it's a website for coding ...it says 3.x

[brazen eagle]

would need a deep copy, ye?

[balmy flint]

deepcopy ?

[true pumice]

Mhm

[brazen eagle]

hmm, I really don't know how python's object model works

[sage urchin]

@rocky latch https://www.freecodecamp.org/ is a good place to start programming.

[brazen eagle]

is it references everywhere?

https://stackoverflow.com/questions/17873384/how-to-deep-copy-a-list this help?

[true pumice]

This is a simple as I can get it in python 3.9.1:

A = [1,2,3]
B = [item for item in A]

[brazen eagle]

https://docs.python.org/3/library/copy.html doc

dunno if the items are independent there @true pumice

[true pumice]

Hm?

What do you mean?

[brazen eagle]

for ints then sure, but for objects they'd be pointing to the same object no?

[true pumice]

A = [1,2,3]
B = [item for item in A]

print(A)
print(B)
A.pop()
print("List A:", A)
print("List B:", B)

Output:

[1, 2, 3]
[1, 2, 3]
List A: [1, 2]
List B: [1, 2, 3]

[novel cobalt]

B = list(A) is easy to read (maybe)

[brazen eagle]

Assignment statements in Python do not copy objects, they create bindings between a target and an object.

from the python doc

[balmy flint]

Well if I doing with copy or deepcopy both the lists get completely immutable in my case

[true pumice]

How could I forget about list

[novel cobalt]

you need coffee☕

[brazen eagle]

yeah but does list do a deep copy or a shallow copy?

[novel cobalt]

deep copy..... iirc

[balmy flint]

Would I rather post a code of mine...and the output ..!

[true pumice]

A = [1,2,3]
B = list(A)
A.pop()
print("List A:", A)
print("List B:", B)

List A: [1, 2]
List B: [1, 2, 3]

[true pumice]

Good idea, brb.

[brazen eagle]

if I had

A = [obj1, obj2]
B = list(A)

obj1.field = "Modified Field"

would obj1 change in both lists?

as both would be bound to the same target?

[true pumice]

If you are storing values in a list, I am sure they are references

[balmy flint]

Is b= list (a) is different from b=a

[true pumice]

What is it called 🤔

Pass through reference?

[brazen eagle]

pass by ref?

[true pumice]

Possibly

[brazen eagle]

that's generally for functions

B = list(A) calls a constructor for list using A as an initialization param

I assume

[true pumice]

I am pretty sure this is being taken out of scope

[brazen eagle]

maybe

[true pumice]

Instead of storing a reference of the list, you are creating a new object.

[brazen eagle]

if list is only holding ints, then it's fine

if list is holding objects, then be careful

as the objects are not independent between both lists

[balmy flint]

I'm confused with this

I am having list of strings

[brazen eagle]

primitives are pretty much immutable

[true pumice]

A = [[1,2,3], [1,2,3,4]]
B = list(A)

print("List A:", A)
print("List B:", B)
A[1].pop()
print()
print("List A:", A)
print("List B:", B)

List A: [[1, 2, 3], [1, 2, 3, 4]]
List B: [[1, 2, 3], [1, 2, 3, 4]]

List A: [[1, 2, 3], [1, 2, 3]]
List B: [[1, 2, 3], [1, 2, 3]]

Yup, you are right hydra.

[brazen eagle]

it's a super common error

[true pumice]

Objects work differently, luckily when embedded objects in lists I don't usually create list copies.

[brazen eagle]

because pointers are hard

@true pumice if you do a deepcopy, then they'll be independent

[true pumice]

Eh, no need

I found a workaround a little while back for my programming assignment 😁

[brazen eagle]

oh dear

[surreal bronze]

What's up 😄

[true pumice]

(I re-wrote the program so I didn't have to use them because they're icky and I hate pass by reference)

[brazen eagle]

pass by reference is useful

[balmy flint]

I'm modifying the contents of lists by assigning to some string...so will it hold for deepcopy?

[true pumice]

It is above my pay grade.

[brazen eagle]

but also tricksy tricksy

naw should be fine for strings

might want to test that though

[balmy flint]

Oh no its not for me here😂

thanks a lot

Hey @tulip sail sorry to bug you, but can you send me the alias syntax for the thmvpn so I can added it to my .bashrc por favor. Much appreciated my friend

[steady anchor]

#programming message

@lilac holly

alias thmvpn="tmux new -s THMVPN \"sudo openvpn ~/Downloads/MuirlandOracle-THM.ovpn \""

[lilac holly]

Hey thank you !! 😊

[steady anchor]

[lilac holly]

Is the backslash the same as piping??

\sudo @steady anchor

[steady anchor]

it is for new line i think

or character escaping

[lilac holly]

Like pythons \n

[steady anchor]

yeah it is for character escaping in bash

[lilac holly]

Noiiiiiice

[solar hull]

above, that " encapsulates a series of words separated by spaces into a single string. As " would end that string, to include double quotes inside the string, they need to be escaped. And that's what \" does.

[lilac holly]

Woah. You are like mind reader. I too was wondering why it only had double quotes at the end and not the beginning

[solar hull]

so the value of that alias called thmvpn is tmux new -s THMVPN "sudo openvpn ~/Downloads/MuirlandOracle-THM.ovpn " after those escaped double quotes are unescaped.

[lilac holly]

And tmux new -s stands for new session correct?

[solar hull]

I'd guess that names the session.

                   (alias: new)
``` Seems like that.

Does importing many modules increase the size of a script

Of the script? No.

The script is just pure text.

Ok does it make the script run slow?

[onyx merlin]

It will increase the footprint in RAM potentially, because it's gotta hold more references and stuff

Don't import stuff you're not using, because that's poor practice.

@ me when answering, ty

[onyx merlin]

That doesn't seem like a programming question?

[dusky niche]

Someone good in C language and reverse engineering?

[onyx merlin]

Just ask your question

[dusky niche]

I am making a ctf. First one. So when running the program you need to enter a key. You will get the flag when submitting the right key. But the key is hidden and the flag not

Idk how to hide that.

Someone told me to encrypt it

But I tried it 1 way. It did work. But when using radare2 it showing the flag

But its hidden with string and ltrace

So you know how to do it?

[brazen eagle]

encrypt it outside the program, and decrypt it live, or encrypt the input and compare against the encrypted flag

you'll probably want to hash it

and then compare the input hash with the hashed flag

unless you want then to grab the flag from the code

fun check_key( String input ) {
  return decrypt(encrypted_flag, key);
}

something like that might work

[onyx merlin]

What's the goal of the challenge anyway?

[brazen eagle]

it'll output gibberish if the key is invalid

[onyx merlin]

Because just use the movfuscator.

[brazen eagle]

that's mean...

also you can debug though that no?

[onyx merlin]

You haven't seen my next box.

Uhhhh

[brazen eagle]

blackbox it is

but yeah depends on the goal

Did you mention this was an exploit?

yes

and hack my own roblox game

🙂

[true pumice]

Ohh no

We do not do that here.

In order to make Roblox cheats you need permission from Roblox

[shrewd raft]

no, but for test my system secure

i have a team

i am on the testing secure now

[true pumice]

Do not think you are reading what I am saying.

[shrewd raft]

?

can you be more specify please

i speak spanish

[true pumice]

In order to exploit a game engine, you need explicit permission from the game creator.

Creating cheats for Roblox is against Roblox's Terms of Service, is unethical and in some cases illegal.

Not only that, but from experience when you have permission from Roblox, they usually do not like you discussing this with others users.

[shrewd raft]

But that is only for owners of the game

for test security

[true pumice]

Does not matter.

[shrewd raft]

Hey,
I want to write a small application that helps me to keep track of summoner spell cooldowns in League of Legends, nothing fancy, just functional. I'd love to have it on an overlay on top of the game, but if that makes it a lot more complicated, then idc about it as much. Now to the question: Do I have to worry about resource usage of my machine (and therefore worse game performance) with such a small application and if so, which language would be appropriate to use or does it even matter at all?

[bitter field]

I think there are already tools for that but if you're interested on making you're own I dont think the language would change much since its such a simple app

[floral wedge]

Oh, I didn't know that. I'll look into it but will probably do it myself anyway. Thanks!

[bitter field]

http://www.loltracker.gg/app/?isDemo=true here is something I found

[floral wedge]

I just found that as well :D

[sharp coral]

i wouldn't worry about resource usage at all, now things may get complicated depending on if custom UI/HUDs are against the Tos/EULA for League of legends, I have no clue on that end

[floral wedge]

There are plenty of them on the Internet and used by popular streamers and no one's complaining, so my guess would be no.

[sharp coral]

okay cool, well my super naive solution would be building a keylogger in python to listen for ability key-presses and have those trigger some timers and then have some simple GUI to house it all off-screen

the right solution would probably involve tracking down the existing HUD resources and doing a little reverse-engineering to figure out how they interact with the game client

and if there's custom UIs online that streamers use you could also track those down and maybe see if there's any useful functions you can rip from github

[floral wedge]

What you said first is kinda what I'm going for, the "right" solution is a bit out of my current comfort zone with such programming (never really did sth like that before and would have to Google more than usual) and I don't want to spend too much time on it since it was just a quick thought I had today. I only ever wrote small programs for the trash can as a matter of learning the concepts in school, never did anything useful or applicable in a real world scenario, so I'm not too experienced.
Thanks for the input!

[onyx merlin]

My recommendation is to NOT test it on your main account, seeing as hooking things can be picked up by anticheats

Question: I have an assignment that wants us to do operations such as A = B * 16, A = B *17, etc in a single instruction using ARM assembly (where signed integers A and B are saved in r0 and r1) . Now, since the MUL instruction only accepts registers and not immediate numbers, for the first one I just went with LSL r0, r1, #4 (aka a left shift by 4 bits). Obviously this doesn't work for something like A = B *17 because that's not a multiple of 2, so I'm totally stuck. Help?

[onyx merlin]

where signed integers A and B are saved in r0 and r1) . Now, since the MUL instruction only accepts registers

So

Oh, right nevermind I see the issue

[red wave]

Yeah the single instruction part is what makes it tough here

[onyx merlin]

http://altmer.arts-union.ru/3DO/docs/DevDocs/tktfldr/acbfldr/2acbb.html This looks like you're stuck at 2 instructions?

Maybe talk to your teacher and say "I think it's impossible because of these well thought out concepts, do you have any advice?"

[red wave]

I think according to the specific problem description, going the route of ADD + bitshifting is an acceptable way to solve the problem? So this helps a lot, thank you!

[onyx merlin]

I'd say it's not a good solution for anything that isn't a power of 2

Maybe it's worth discussing the limitations in whatever you're submitting?

[prisma thorn]

alright, so using cpp, because I want speed and other reasons

I am trying to iterate through the argv list, in order to get arguments like -p -o etc
however, when I run the code without the little things I added, it compiles/runs fine, but adding the below code gets me

terminate called after throwing an instance of 'std::logic_error'
what():  basic_string::_M_construct null not valid

This is the code

for (int i=1; i<=argc; i++) {

        if (argument.compare("-p") == 0) {
            cout << "You want a password checked?\n";

    }

Any ideas as to why?

I figured it out.

How to make an .then

on C#

[cursive orchid]

big question mark to the above question

does c# even have promises

i'm using react and i'm trying to dynamically load md files, however i have no idea how to approach this

import file from '../blogs/Test.md';

fetch(file)
    .then((res) => res.text().then(console.log))
    .catch(console.error);

this is my current code which loads the file just fine

however, i need to get the blog id from the url, and load that blog, rather than Test

but react insists that import statements be at the top of the file

and using require to get the file doesn't work for some reason

import file from '../blogs/Test.md';

const Blog = (props) => {
  const { blog } = props.match.params;

  fetch(file)
    .then((res) => res.text().then(console.log))
    .catch(console.error);

  return (
    <>
      <h1>{blog}</h1>
    </>
  );
};

export default Blog;

this is the full file atm

[crisp turtle]

Isn't fetch for http requests? So, couldn't you just pass it a string or whatever?

[cursive orchid]

if i pass it a string then it for some reason grabs the index.html

fetch('../blogs/Test.md')

[crisp turtle]

Are the md files available through the webserver? I know react is a client side framework so, you would need a webserver to host the MD files.

[magic falcon]

Not as such... The equivalent to a promise the 'future'. You'll see that in C++ concurrency/asio libraries as well as in C#.

[cursive orchid]

i have them in the public directory so they are being hosted

but no worries, i got it working

import { useEffect, useState } from 'react';

const Blog = (props) => {
  const [blog, setBlog] = useState('');
  const [error, setError] = useState(false);

  useEffect(() => {
    const url = `http://localhost/blogs/${props.match.params.id}.md`;

    const getBlog = async () => {
      const response = await fetch(url);
      const file = await response.text();

      return file.includes('<!DOCTYPE html>') ? setError(true) : setBlog(file);
    };

    getBlog();
  }, []);

  return (
    <>
      <h1>beep</h1>
    </>
  );
};

export default Blog;

works just fine

Hi, I'm working on tool that checks MD5 hashes .. and I wonder if it's possible in python to make update just the variable with hashes on screen without having to clear whole screen

output:
TRYING HASH: '{Hash variable}'

Is it possible in python to update only that variable without clearing whole screen ?

[true pumice]

You can do this!

Here is an example I wrote up:

import os, time

for x in range(20):
    with open("example.txt", 'a') as file:
        file.write("test")
        
    print(os.path.getsize("example.txt"), end='\r')
    time.sleep(1)

The print statement, like all functions, takes parameters. The key one is end.

https://docs.python.org/3/library/functions.html#print

( @lilac holly )

[lilac holly]

I'll try it

ty very much

[lilac holly]

well but if I use os.system('clear/cls') it will remove the "crakcing hash" part but I need to remove only the hash it self (sorry for bad english)

[shy socket]

use the end='\r' method. It resets the cursor to the beginning of the line. You will have to rewrite the CRAC.....HASH part, but is that really a problem?

alternatively use curses

quick example like :

import curses
import time
stdscr = curses.initscr()
stdscr.clear()
stdscr.addstr(0, 0, "[i] CRACKING HASH : ")
stdscr.addstr(0, 20, "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA")
stdscr.refresh()
time.sleep(1)
stdscr.addstr(0, 20, "BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB")
stdscr.refresh()
time.sleep(1)
stdscr.addstr(0, 20, "CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC")
stdscr.refresh()
curses.endwin()

AAAAA .... being the hash

if hash is not same length the use stdscr.clrtoeol() after each addscr to remove excess chars

[lilac holly]

ty

I was looking to curses rn

this helped me alot

ty

[shy socket]

btw the 20 in the addstr is the character number where it puts the cursor on the line

This looks like a mis-use of IOCTL to me. Someone with more understanding of C device drivers should weigh in too, but IOCTL is intended to manage connected devices; there are other device config flags that may need to be set to manipulate a fd with that lib.

my idea was to take the hex value mask it and then use right shift operator and store it in an array

[novel pulsar]

I see where this going 😂

[steady anchor]

#include <iostream>

using namespace std;

int main()
{
    unsigned int long foo = 0xFC4883E4;
    unsigned int long d1;
    unsigned int long d2;
    unsigned int long d3;
    unsigned int long d4;
    
    d1 = foo & 0xFF000000;
    d1 = d1 >> 24;
    d2 = foo & 0x00FF0000;
    d2 = d2 >> 16;
    d3 = foo & 0x0000FF00;
    d3 = d3 >> 8;
    d4 = foo & 0x000000FF;
    d4 = d4 >> 0;

    int arr[4] = {d1, d2, d3, d4};
    cout << hex << arr[0] << endl;
    cout << hex << arr[1] << endl;
    cout << hex << arr[2] << endl;
    cout << hex << arr[3] << endl;
    return 0;
}

this should work

now gimme my cookie

[remote echo]

But i think he was asking it was string "fc4883e4" not unsigned int

[steady anchor]

[remote echo]

And even if he wasn't asking, i would like to know

[steady anchor]

but why would use sth like hex as string

is there a thing called string to ascii

[remote echo]

suppose u get a string as "fc4883e4" then how would u conver it ?

In python, i might use a loop

To get [n:n*2] element

And then int('element' , 16)

No idea about cpp lol

[steady anchor]

there is a manual way but i would not look nice

wanna see my weird programming skills

[remote echo]

Ping me after you figure out ur cpp-fu lol @steady anchor

[steady anchor]

[snow smelt]

@steady anchor this is not indeed the right solution as you define unsigned int long foo = 0xFC4883E4;

The challenge is that it has to be string of any length containing valid hex system characters (e.g it could be std::string s = "fcab27bcd80e1ab25ced1683fffce3ed"

This string's length is 32, meaning that we need to end up to some byte array ba[] = { 0xfc, 0xab, ..., 0xed }
an array with size = 16

[steady anchor]

:rip:

why is this string so long

i thought it would be pointer

[remote echo]

I told ya @steady anchor

[steady anchor]

let me see what can i do

[remote echo]

@snow smelt is it being cpp mandatory?

[steady anchor]

i know there is easy way

[steady anchor]

you wanna do it in python?

[remote echo]

Not kidding lol, i don't know cpp

That's why i was asking

[steady anchor]

cpp is c

both of them should work

[remote echo]

So we can use stoi()

[steady anchor]

yeah

it is backward compatible

use can use c libraries

[brazen eagle]

stoi doesn't work on hex AFAIK

strike that it does

stoi won't give the arbitrary length byte array though

[remote echo]

I tried to write something in C, but in the end, I could not lol

[brazen eagle]

haha

I'll have to give it a go then

string = "fcab27bcd80e1ab25ced1683fffce3ed"
array = []

for i in range(0,len(string)//2):
    hex_value = string[i*2:(i+1)*2]
    array.append(hex(int(hex_value, 16)))

print(array)

here is python code

no one asked for lol

['0xfc', '0xab', '0x27', '0xbc', '0xd8', '0xe', '0x1a', '0xb2', '0x5c', '0xed', '0x16', '0x83', '0xff', '0xfc', '0xe3', '0xed']

^^output

hehe

[remote echo]

just to satisfy my bursting head lol

[snow smelt]

@remote echo yeah that py code will work just fine! cpp time now 😄

[brazen eagle]

do they want the byte array as a return?

[remote echo]

I am having headache out of it lol

[eager sail]

do i need to learn programming for cybersec?

[brazen eagle]

if the byte array the return or the print to screen?

[steady anchor]

there are no strings in cpp there are character arrays @remote echo

[brazen eagle]

there is std::string

[remote echo]

No, but it will be beneficial if u do

Yes

I read today

[steady anchor]

it used power of library and hard work of some developer

[remote echo]

There is string

[steady anchor]

it is all character arrays

[snow smelt]

also, consider the null terminator of strings 💩

it's a bit challenging

[steady anchor]

challenge not accepted

i am going to sleep

[snow smelt]

[brazen eagle]

that should be taken care of already

[remote echo]

Today i was going to start learning cpp lol

not it feels like hard af XD

isn't there a fun way learning it

[brazen eagle]

ah, I see

ha

[remote echo]

#include <stdio.h>
#include <stdint.h> 
#include <string.h>

int main ()
{
    char *hexstring = "fcab27bcd80e1ab25ced1683fffce3ed";
    int i;
    unsigned int bytearray[16];
    uint8_t str_len = strlen(hexstring);

    for (i = 0; i < (str_len / 2); i++) {
        sscanf(hexstring + 2*i, "%02x", &bytearray[i]);
        printf("bytearray %d: %02x\n", i, bytearray[i]);
    }

    return 0;
}

@snow smelt check this

[brazen eagle]

easy way to overflow the buffer there

[remote echo]

i didn't code it btw

XD

[remote echo]

Yup

[brazen eagle]

I'm having issues with the byte array

[remote echo]

@brazen eagle u said about buffer, but keeping it 16 is fine right?

i mean, what is vulnerable or bad

[brazen eagle]

it's the fixed length

[remote echo]

can u elaborate plz

i would like to know
