I need a little help with qt5. Somehow it produces this error and doesnt open. Ive read sth about local variables not being set correctly but dont know what to do with that. Ive tried reinstalling qt5 but that didnt fix it. Any idea on how to get it working again?

[surreal bronze]

Okay

Have you searched on google this error?

[floral wedge]

yeah sure. Thats where I found out about the local Variables but that didnt really help me because I dont know what it is and what it has to do with qt5.

[surreal bronze]

What does the qt5ct supposed to do?

[floral wedge]

https://wiki.archlinux.org/index.php/qt

open this tool

[surreal bronze]

Ah the configuration

[floral wedge]

yeah

[surreal bronze]

What is your OS?

[floral wedge]

I want to use dolphin file manager on arch with gnome desktop

But dolphin is a KDE package and doesnt accept the system default theme of gnome, which is why I wanted to use qt5 to change that

[surreal bronze]

I see

In /etc/environment

What is the value of

QT_STYLE_OVERRIDE

[floral wedge]

dont have that

[surreal bronze]

Okay I'm reading from this

https://stackoverflow.com/questions/61509812/issue-glib-gobject-warning-cannot-register-existing-type-gdkdisplaymanager

Any of these solutions working for you?

[floral wedge]

nope :/ but I also dont have the qt5ct.conf the guy is talking about. Maybe thats it.

[surreal bronze]

Maybe it is

If that doesn't run you could try with different qt versions and see if it's that

[floral wedge]

Good idea. Ill try that and come back here if it doesnt work, thanks!

I installed qt6ct and it works just fine :)

[surreal bronze]

Aye! 🙂

[north heron]

i had a dream that someone hacked my pc again Lmao

i'm going crazy

[echo karma]

hey bro

@north heron you got hacked?

[north heron]

ye

[echo karma]

explaid how it happen

maybe you have risky behavior

downloading apps

[north heron]

no, i used a common password

[dusty ore]

It would be great if someone can help me

I'm kinda new to coding

I'm like making a "bot thingy"

I'm using selenium to automate the process of: going into the url -> doing stuff

But the url requires a token id

like this lmao.com/?token=123

So I have a list of some token id (which I create a new account to get those)

put it in a json file

and put these 2 lines of code

nah wait i think im figuring it out

lol

[echo karma]

@dusty ore JohnLmao how much old are you

[dusty ore]

ah umm im 16

[echo karma]

mmm... use selenium or imacros

its aboslutly wasted time

use javascript

[dusty ore]

javascript huh

[echo karma]

yes ofcourse

[dusty ore]

like can it do

go to the website, press a button, etc..

[echo karma]

using a browser extension

[dusty ore]

im kinda stupid

[echo karma]

dev a browser extension

use a chrome extension or firefox extension to do so

[dusty ore]

hmm thats a nice suggestion, thanks

but i guess ill still stick to python as im studying it

its a good practice tho

[echo karma]

may be

an chrome extension is easy to do and its javsacript 100%

and you can upload script in chrome market

and use it anywhere

[dusty ore]

oh ye

but this is a temporary project

Like it will be very useful but it will be useless after a month

[echo karma]

so you can use imacros if its easy task to do

[dusty ore]

thanks, ill have a look about it

[echo karma]

but there

this is asking for path to .json

json is key value file

{key:value}

i dont know what are you doing, if you show me more code may can help more

[dusty ore]

oh ye i forgot to tell you

I changed .json to .txt

and used open

its easier

[echo karma]

great

if you need help let me know

also i can do a chorme extenson fast for you

i have template ready to do so

[dusty ore]

Thanks but I think I'll do it on my own

studying ya know

hehe

[echo karma]

yes, its very easy jhon!

[dusty ore]

Ye

Thanks for your help

[true pumice]

@cursive orchid I know the issue with your JS script

(If you still need help that is)

[vagrant zodiac]

anyone who could help me out with the csv module in python?

[onyx merlin]

Just ask

[vagrant zodiac]

well i have a file open, witch im hashing the passwords in, that woorks well when printing to the terminal.
not so good when im trying to write them to a new file

[surreal bronze]

Can you provide the code

[vagrant zodiac]

yess sir

https://github.com/Ptotheo/RainBowReader

so the testpw has some passwords i want to hash to make a rainbowtable. and the rainbow.csv is where i want to store them

[brazen eagle]

your row seems to be out of scope

unless I'm missing something

salt too

why are you salting a rainbow table though?

[vagrant zodiac]

no reason, used that for another script so just pasted over until i get this to woork

how is it out of scope? for row in "file", what else could i do?

[brazen eagle]

not what I'm seeing

with open("testpw.csv") as passwords:
    for row in passwords:
        salt_sha512 = crypt.crypt(row, crypt.mksalt(crypt.METHOD_SHA512))


with open('rainbow.csv', 'w', newline='') as rainbow:
    fieldnames = ['password', 'hash']
    writer = csv.DictWriter(rainbow, fieldnames=fieldnames)

    writer.writeheader()
    writer.writerow(f'password: {row}, hash: {salt_sha512}')

this is what I see

[vagrant zodiac]

ooh so you would do "for row in testow.csv"?

[brazen eagle]

just saying that in the rainbow block, row no longer exists

[vagrant zodiac]

makes sence its outside the block, but ive tryed with it inside to, im doing somthing wierd..

[brazen eagle]

might want to transfer to an intermediate dictionary

[vagrant zodiac]

makes sence, ill try:)

[magic falcon]

you are trying to implicitly scope row to global, when it is a transient object

[sharp coral]

Have a good self-study problem I'm stuck on. Need to generate list of passwords. I'm given 3 separate lists. 4th list is user-generated and varying length depending on cmdline arg. The main problem is this, each password must consist of only ONE element from each list - meaning I will need to generate every possible permutation within these constraints. Itertools is doing the heavy work here but its still confusing as heck.
my code so far and problem prompt are at https://github.com/Droogy/programming-training/blob/main/Problem1/

would def appreciate any guidance!

[vagrant zodiac]

did not get it to woork.. ill try again tomorow, thnx for the help anyway

well thnx @sharp coral you had the answer to my question in your code XD.

[sharp coral]

haha glad I could help somehow!

[onyx merlin]

I'd just do four nested loops...

[sharp coral]

thank you I'll give that a try

[true pumice]

I think I have a working version of your problem Droogy so ping me if you need a little nudge and I'll assist :)

[sharp coral]

will do! appreciate you taking a look

[brazen eagle]

that'll work

unless order needs to be taken into account as well

[onyx merlin]

Depends what you mean by order

[brazen eagle]

lists can be in any order

[onyx merlin]

Because it will be in order, in the order of the list

[brazen eagle]

ie 1, 2, 3, 4 or 4, 3, 2, 1

or 2, 4, 3, 1 (for example)

so there'll be more than 4 loops nested

[sharp coral]

thats correct hydra, i need all permutations like that so

1234
1243
...
4321

thats my expected output

[brazen eagle]

yeah so there's 4! permutations, assuming I'm not forgetting my combinatorics

[sharp coral]

gah Im right back where I started with the 4 nested loops vs. itertools

[brazen eagle]

this is a fun question, I might steal it as a kata

[magic falcon]

that was what i got, hydra n * m * o * p * 24 unique orderings

[brazen eagle]

so yeah a good chunk

[sharp coral]

it is a fun one, a friends mom forwarded me this, shes an IT exec and said one of her engineers made this question for new hires

[mellow moth]

Guys, I'm taking a cybersecurity course from ine.com, and in the second module they ask for do a simple exploitation writing a program with c++, and is recommended to use a dirent c++ library and winsock, because the goal is steal the directory info from the lab.

So, my question is in the fact that, I'm doing it, through a lot of read in internet and I have some knowledge in programming because I'm a front-end developer, but the thing is that I don't feel satisfied just being able to do and many things seem so obscure in C++, but when i tried to understand some pieces they grow into bigger ones, and it seems very hard to get all concepts at once.

I would like to know if in your study you were studying every little thing, like networks, tools, programming simultaneously or if you specialized first, like low level programming and then to the next step.

Sorry for my english.

[sharp coral]

if its for eJPT, I wrote that module in Python, try and adapt new things to your existing skillset and throw away things that don't fit

theres a lot of foundational topics you should understand to break into IT in general, and a further subset of those foundations is necessary for infosec

but don't try to do all the things at once, networking is a great place to start learning imo

[mellow moth]

I think i understood, about networking i'm studying a lot, but my concern was to not have a deep knowledge in low level programming and this will end up impacting me in the following studies, but your tip, about focus in my existing skillset will be very useful, thanks.

[sharp coral]

no, low-level programming is good to have a general understanding of, but is generally a pretty niche skillset in infosec usually reserved for malware analysts/reverse-engineers

[mellow moth]

Oh, right.
Thank you again!

@wispy tusk

[wispy tusk]

This is not the solution I'm looking for. Doing this will remove my entire git history. I just want to remove history of a single commit. I've searched a lot but this is the solution I found in all the search results.

[true pumice]

https://stackoverflow.com/questions/30893040/git-remove-commit-from-history

You cannot ask how to do something with a very vague request and expect me to know what you want.

[wispy tusk]

I have explained my problem in the question I posted on stack overflow and also mentioned in the body that I want to remove the history of a specific commit.

[true pumice]

And I linked you plenty of resources, if you aren't going to read the ones I linked then don't complain.

[wispy tusk]

I'm not complaining. I just explained myself. I am reading all the resources you provided one by one. I just replied to the first one among them.

I read all of them...same thing. Not what I'm looking for

[true pumice]

You asked how to remove a commit from the history

[wispy tusk]

I asked "How to remove history of a specific commit”

[lilac holly]

32

[wispy tusk]

I already removed a commit, now i want to remove the information Stored about it in the history.

Googling the problem results into the same solutions which you provided. That's the very reason I asked here and posted it on stack overflow.

[slender nymph]

Heya! So I was hoping someone could give me some ideas of how I can get this to properly spit out into clipboard. I started practicing python a solid hour ago after not having touched it since middle school.

Phone_Number = input("Enter five digits for PhoneNumber: ")
First_Name = input("Enter a first name: ")
Last_Name = input("Enter a last name: ")
DOB = input("Enter a date of birth. Year-Day-Month Ex;1996-07-13: ")
Result = "/me hands over their ID\n^*^4 [ID]^r: TID #: ^2"+Player_ID+"^r SSN #: ^2 "+Phone_Number+" ^r | First: ^2"+First_Name+" ^0/ Last: ^2 "+Last_Name+" ^0| DOB: ^2 "+DOB+" ^0|_"

import pyperclip
myStr = Result
pyperclip.copy{myStr}```

It's a program made for a GTA RP server I used to play on. It's what I like to use instead of hello world.

[true pumice]

So what is your end goal exactly?

/me hands over their ID ^*^4 [ID]^r: TID #: ^2123^r SSN #: ^2 12345 ^r | First: ^2abc ^0/ Last: ^2 def ^0| DOB: ^2 1996-07-13 ^0|_

Seems to work fine

The only thing I changed was:

import pyperclip

pyperclip.copy(Result)

[slender nymph]

Honestly everything so far seems to work out. Everything from Player_ID to DOB should be user input. I am just not understanding why I can't get it to clipboa-...

[true pumice]

Mhhm, all you had was a syntax error.

Usually when calling functions you use (arguement), as opposed to {arguement}

[slender nymph]

Might need to restart some stuff. As I'm still running into an error.

[true pumice]

Here's the whole program with changes:

Player_ID = input("Enter Server ID: ")
Phone_Number = input("Enter five digits for PhoneNumber: ")
First_Name = input("Enter a first name: ")
Last_Name = input("Enter a last name: ")
DOB = input("Enter a date of birth. Year-Day-Month Ex;1996-07-13: ")
Result = "/me hands over their ID\n^*^4 [ID]^r: TID #: ^2"+Player_ID+"^r SSN #: ^2 "+Phone_Number+" ^r | First: ^2"+First_Name+" ^0/ Last: ^2 "+Last_Name+" ^0| DOB: ^2 "+DOB+" ^0|_"

import pyperclip

pyperclip.copy(Result)

As you can see I only changed the bottom, I may add defining the variable myStr to store the value of Result seems entirely pointless in this program

What error is occurring for you?

[slender nymph]

I did add a pointless string... Seems PyCharm refuses to believe I have Pyperclip setup.

[true pumice]

Ah, I do not use PyCharm. I am using the default Python shell.

[slender nymph]

I'll work this out, Though I appreciate your help and thank you for noting the useless string. Much I still need to get a grasp on.

[true pumice]

Mhm, no problem

[vernal vigil]

[true pumice]

Hm?

[vernal vigil]

Nothing

[true pumice]

Ok...

[slender nymph]

I think I found what I did wrong, now I just need to figure out how to resolve it... Say just to make sure I was the big dum... Would me throwing in the pip for pyperclip while it's still in a temp\Rar folder be the reason I am now getting a fileNotFound error?

[true pumice]

Does it specify which file is not found?

[slender nymph]

src/pyperclip/__ init __.py

[true pumice]

Not sure how PyCharm works, if it has a console/ package manager try installing pyperclip through there, if not manually copy and paste the pyperclip files to the directory requested. (Be sure not to delete the original files just in-case)

[surreal bronze]

the only good thing about pycharm is its debugging

[slender nymph]

We gottem boys! I'll be honest. I just close the entire enviroment out and started anew with the same code. Works fine now after dropping pyperclip back in.

[true pumice]

👍

[magic falcon]

PyCharm likes to set up a venv specifically for the project. Ensure that your requirements.txt stuff is installed into the proper place

[brazen eagle]

in theory, you don't, that's the whole point of git. In practice, I think there are ways to poke at the reflog

https://docs.github.com/en/github/authenticating-to-github/removing-sensitive-data-from-a-repository this may help, @wispy tusk

the BFG might work

but because commit history is a graph, removing one single commit will completely break the graph

[wispy tusk]

The problem is I don't have any file to remove. This is a guide which tells how to totally purge a file including its history but I have already removed the file. I just need to clear the history of that deleted file

[brazen eagle]

the file is probably still there then

git doesn't work that way though, it doesn't know about files

[wispy tusk]

I have deleted the commit using interactive rebase. It is a safe method.

[brazen eagle]

ok then what's the problem?

[wispy tusk]

I have checked, It dosen't show up in the git log

[brazen eagle]

interactive rebase rewrites the history

you'll probably need to force push the changes

[wispy tusk]

Yup so i can use it to rewrite the history and exclude a specific commit in the history while rewriting it..thats the trick

[wispy tusk]

Ya I did..my origin master and local master are on same level

[brazen eagle]

so what's the problem?

you rewrote the history, the original commit no longer exists

we're good, no?

[wispy tusk]

'ab472' This is the hash of the commit I removed. It doesn't show up in git log anymore. But when I use git show ab472, it shows all the detals of that commit

https://github.com/7Ragnarok7/DEDMAP The remote repo. It is in par with my local repo. You can have a look

[brazen eagle]

have you tried to gc?

might be some housekeeping options on github as well

[wispy tusk]

No, I'm not sure what It does.

[wispy tusk]

Oh so it cleans up the repo..okay...just did it.

Still the commit is being shown while using git show

[brazen eagle]

try git reflog expire --expire=now --all && git gc --prune=now --aggressive

(from the BFG homepage https://rtyley.github.io/bfg-repo-cleaner/)

[wispy tusk]

No effect at all, still shows up.

[brazen eagle]

normally what happens in git stays in git. Is there a reason why this commit needs to disappear?

[wispy tusk]

It is a commit committed by some other person with the username shubhayu-64. I have removed the commit but the contributor's name is still being shown in the contributor's section. That's strange.

[brazen eagle]

is that a problem?

or did you forget to protect master?

[wispy tusk]

Yes that is the reason I am trying to remove that specific commit and its history. When I started the project I had least idea about git and github and I added lots of people as contributors rather than following the gitflow, which created a big mess.

[brazen eagle]

https://gist.github.com/stephenhardy/5470814

seems you may have to nuke and pave, though there appears to be a -mirror option

git is made to keep history as robustly as possible

[wispy tusk]

I successfully removed the commit and now The readme file which that other user commited on is now showing only 1 contributor i.e. me, but in the remote repo the name of the contributor is still being shown even though presently there is not commits in the repo by that user.

[brazen eagle]

git push --mirror --force ?

[wispy tusk]

This is an obvious option but doing this will remove all the history of all the commits

[brazen eagle]

yeah

[wispy tusk]

Not working...

Anyways thanks for your help @brazen eagle 🙂

[brazen eagle]

nuke and pave then, probably, sorry

[cursive orchid]

@true pumice aww thank you

but i fixed it now

[true pumice]

What did you do to fix?

[cursive orchid]

it's because i was mutating the array directly without making a copy of it first

it was something like

oldCells = [...oldCells];

if () {}
else {}

return [...oldCells];

had to add that top line

i don't fully understand why that works, but i was told i can't mutate the array and then return the copied value or smth

[true pumice]

The reason for the if and else statement both running was simply because it was checking a value which was null

[cursive orchid]

i was checking if it wasn't null though in the if

[true pumice]

Mhhm, I asked my brother and he told me how to change the program to make it work but I can't remember 😄

[brazen eagle]

ah arrays are by ref yeah

[stone kayak]

How would you test a web-crawler against live websites / IPs?

I'm thinking:

• pytest-mock the API calls locally so local test times are decreased
• test against live APIs in CI as part of integration testing, and CI can run much longer than pytest can on a small devs laptop etc
• Test against external websites (?) such as those not controlled by the organisation to see if it can hold up (but mark those tests as can-fail, so if they do fail because of an external website going down CI isn't down)

That last point is kinda ??? for me as I'm not sure on best practices 🙂

This is 100% a homework question but I just wanted to triple check with people who are in industry, as well uni didn't teach me these things hahahah

[brazen eagle]

maybe use an existing spider such as that used on ZAP and compare to your results?

or manually trawl through the site to see what you find?

[stone kayak]

this is for an enterprise production environment™️ not something I'm doing, it's just bringing up points of what should the testing look like 😄

[brazen eagle]

I'd have a known good and compare against that

also go annoy the site devs

😄

but external sites are always iffy to test against,

integration tests need to be on live, but controllable data

[stone kayak]

Is it too much if I say "deploy a website with cyclic links, broken links, etc on an EC2 instance in a different region"?

[brazen eagle]

ooh that'll break things nicely

why not locally in a docker container?

[stone kayak]

cause we can control that I think, we can deploy it with CI whenever we want and we don't rely on someone elses site

[stone kayak]

Not locally as we want to test latency, network connections between the server and the real world etc

[brazen eagle]

to the crawler it's all the same

ah ok

[stone kayak]

hey i think im actually pretty good at this hahahaha

[brazen eagle]

sure, different regions are always good

[stone kayak]

it would cost money, but if its essential for the business it's the best we can do I think

[brazen eagle]

have a few links to example.com in the test site

or google

or other big sites that don't change much

While it shouldn't happen - have a plan B for your spidering to crater the webserver. Especially if it's a seldom-used intranet server

does anyone know pyautogui here

or how to use it

if so can u tell me if pyautogui have some kind of key detecter

like

if it can see if ur holding down right clicke

yk keystroke

s

[onyx merlin]

Stupid keystroke thing?

[surreal bronze]

You mean a keylogger?

[lilac holly]

whats that

[onyx merlin]

What are you trying to accomplish? Describe it.

[lilac holly]

ok have u heard of minecraft keystrokes

if u press w it highlights w

press a it highlights a

well i was bored so i was like hey why not make a keystroke but like just a fun program

[surreal bronze]

You want a GUI that highlights the key you press?

[lilac holly]

ya

if its even possible, but it should be

[true pumice]

You can but Python probably is not the best for that.

[surreal bronze]

Well it is possible quite easily

[lilac holly]

yeah

[surreal bronze]

Just use the keyboard module

[lilac holly]

wait what

theres a keyboard module

???????

stdlib?

[surreal bronze]

It has a function to check what key is pressed

[lilac holly]

wow thats useful

can it check mouse clicks

[surreal bronze]

https://pypi.org/project/keyboard/

I don't think mouse clicks

[lilac holly]

if it cant, ill just use pyautogui to check

well tysm

this module will defo help me alot

im also trying to practice pyqt

[surreal bronze]

👍

hi

[pulsar sierra]

Anyone good enough to help me with a issue with JS ? Don't hesitate do DM me, I could send it here, but I don't know if I'm allowed lol

[true pumice]

If you're not allowed to send it here, there is a chance you're not meant to be discussing it at all.

[onyx merlin]

Why don't you think you're allowed? @pulsar sierra

[pulsar sierra]

Oh lol that's not what I meant, I just didn't know if it's the right channel ^^

[pulsar sierra]

☝️

[true pumice]

If it's programming, it is allowed. Ask away.

[pulsar sierra]

Alright

So I have this code

function getApiResult(url, data) {
    fetch(url).then(
        response => {
            return response.json();
        }
    ).then(result => {
        for (var i in result.results) {
            data.push(result.results[i])
        }

        if (result.next == null) {
            return;
        } else {
            getApiResult(result.next, data);
        }
    })
}

let data = [];
getApiResult("http://localhost:8000/api/v1/titles/?sort_by=imdb_score&imdb_score_min=9", data);
console.log(data);
console.log(data[0]);

But when I execute it, I get this in my console :
[]
undefined
While testing, I understand that when the console.log(data) at the end is not fully loaded (waiting for the fetch to finish) ...
I don't get how can I exploit data, only when it's finished :/

PS : I already tried to put it in an async function and make await GetApiResult("...", data) instead of what I have right now

[true pumice]

(As long as it follows the rules of the server and laws)

[pulsar sierra]

Of course :)

[brazen eagle]

ah promises

[pulsar sierra]

D: yeah

[brazen eagle]

you won't get your data back immediately

but the code will continue as if it did

await should work though

though I don't know how the recursion will work with promises

[violet cipher]

getApiResult("http://localhost:8000/api/v1/titles/?sort_by=imdb_score&imdb_score_min=9", data);
you need to set a value for data in order to properly enter the function
For example: let data = [1];

[pulsar sierra]

Actually, I fixed it since

But thanks though

[violet cipher]

The one outside the modal is submitting, the one inside the modal is not.. How come?

[solar hull]

I'd like to say it's because your indentation isn't consistent, but that's not the reason

[tribal smelt]

I will apologize for that in advanced, I know it's brutal but this is quick and dirty.

[brazen eagle]

you can add highlighting to the code with \``` html

minus one ` I really have to look up the escapes

[onyx merlin]

Backslash as usual

```html
CodeGoesHere```

[brazen eagle]

bah

what james wrote

[tribal smelt]

I will do that in a moment.

[brazen eagle]

<button type="button" id ="submit" value="submit" form="myForm" formmethod="post">Submit</button>

[onyx merlin]

That was six backslashes. More escapes than an open air prison. Aaaaaaa.

[brazen eagle]

that's different

yeah but I tried to enclose in a ` ` block

which makes the parser derp out

[tribal smelt]

there.

it's all nicely indented and pretty colours now

[brazen eagle]

<form id="myForm" method="post" action="authenticate.php">
                <div class="input-line">
                    <input id="email" type="email" name="email" required
                        placeholder="E-mail" class="input-name">
                    <input id="password" type="password" name="password"
                        required placeholder="Password" class="input-name">

                        form="myForm">Submit</button>
                </form>
            </div>

the divs are off

at least closing tags

[tribal smelt]

oops, i changed that previously.

[brazen eagle]

dunno if the form attribute is strictly necessary on the submit button

[tribal smelt]

I ain't sleeping until I get this whole thing working so it's gonna be a lateeeeeee night for me

nah, that was a test thing as well

[brazen eagle]

shouldn't the form have a name attribute for that to work?

[tribal smelt]

possibly, I'll give it one and test

negative

if anyone comes up with a possible solution, can they @ me please.

[brazen eagle]

copy pasting the form outside the model inside seems to work

[tribal smelt]

@brazen eagle What do you mean? its 1:24AM here, I'm gonna be a little slow.

forms are wierd sometimes

[tribal smelt]

Can I dm you?

heyooo

@brazen eagle ❤️ ❤️ ❤️ ❤️

[brazen eagle]

sec, work

[tribal smelt]

no problem

[brazen eagle]

ok what's up?

[fathom idol]

Has anyone ever gotten WPA2 handshakes to be properly captured in Scapy?

[remote echo]

https://www.evanmiller.org/you-cant-dig-upwards.html

[hazy breach]

I've written a function in python, which loops through the wiki streams API, giving me events as they happen.
I'm processing the events and collecting data.
I want to print the processed data at one minute intervals. What would be a simple solution to maintain a timer parallelly?
I googled and started reading up on asyncio but got a little lost. xD

[modern laurel]

import time

you can use time.sleep(seconds you want)

[hazy breach]

I don't need to pause the code

Let's say I get one event every 11 seconds in the loop I'm processing.
In 55 seconds, I'll have five events...
In 66 seconds, I'll have six events....

When 60 seconds of computation has been done, I need to print the results and continue processing for the next minute

[modern laurel]

i understand that you want to run event in background after that print the data

am i right? btw sorry my english is little bad

[hazy breach]

Check this out
https://wikitech.wikimedia.org/wiki/Event_Platform/EventStreams#Python

See that for loop? I don't have control over how often an item arrives there

[modern laurel]

ok

[magic falcon]

you're looking for a producer-consumer relationship, each on separate timers

effectively, your consumer is looking at a queue being fed by the producer - once a minute, check the queue. if nothing is there, go back to sleep.

[hazy breach]

I'll search this up

Thanks

[magic falcon]

if you dont' understand how python multiprocessing libs work, feel free to follow up

[hazy breach]

I don't, not yet at least. I've just started reading up on them.
Any good starting points which aren't hugely in depth?

[magic falcon]

the python docs are pretty good - caveat there is i already had an understanding of POSIX threads, so the python stuff is super simple in comparison

pretty good intro in java: https://www.toptal.com/software/introduction-to-concurrent-programming

[remote echo]

@hazy breach i didn't get ur question completely but, threading module might help. threading.timer or something. Set timer of 60s

[hazy breach]

Thank you @magic falcon and @remote echo

[sonic root]

You can use threading library

[hazy breach]

Thanks @sonic root, I'll check it out

[lilac holly]

anyone here familiar with syscalls?

got a question about virtualprotect vs ntprotectvirtualmemory

[tulip sail]

@clear needle

[stone kayak]

I have an API that users (probably malicious) will use. I can either:

• Have them write to an S3 bucket their input, a program will check their input and then commit to database if valid (and not malicious). Delete the S3 items.
• Have them write to the database, perform a query to find all unchecked items and then calculate if malicious / valid input. If it is, tick a box and put it into S3.

Which one is better? I'm also storing a manual backup in S3 (hence why it puts it there in the 2nd point). Should I go #1 and stop the manual store?

[brazen eagle]

you can rate-limit the API

[brazen eagle]

but for validating, that seems overly complex

why not pass it through a validation function which forwards it to the api if it's clean?

or is said input a file?

[stone kayak]

We have to compute the validation, I.E. Run a calculation for ~2 seconds

[brazen eagle]

feels odd, but without knowing anything about the input or the api it's hard to say

sorry

[stone kayak]

Sure, the input is a hash : plaintext: type, the validation is validating that hash(plaintext, type) == plaintext. This is expensive and takes around 1 - 2 seconds depending on the type 😅

[brazen eagle]

ah ok

[stone kayak]

I think letting them build up and validating all in one go, say once per day or so is cheaper than validating on the fly

[brazen eagle]

hash(plaintext, type) == hash no?

[stone kayak]

especially with a Lambda function haha

[stone kayak]

you are right, i am stupid

[brazen eagle]

naw

the former then

[stone kayak]

I think writing to the DB is fine, I can rate-limit to 1mb / day as 1mb is fine ? 😄

[brazen eagle]

1mb is pretty huge

[stone kayak]

API gateway limits all requests to 10mb, whereas S3 would be unlimited lol

[stone kayak]

exactlyyy

[brazen eagle]

can you rate limit to n/s to avoid DDOS

[stone kayak]

yeeee its limited to 1/s, the DB only supports 5/s anyway 😛

[brazen eagle]

right

so caching results for a day and processing as a batch seems alright, so long as there is no expectation that the input is queryable immediately

you can always batch at a shorter interval

[stone kayak]

its probably better if i write a short lambda func to check how many unverified things are in the DB and if it reaches a threshold, run another lambda func? that way its not determined by time but by usage 😄

[brazen eagle]

maybe

[stone kayak]

and that shorter one can run a lot more since it'll only exist for a few ms

ah wait, i can just do that check in the main lambda func anyway -- so if there is stuff to add, add it else exit?

[brazen eagle]

might save the spinup time

[brazen eagle]

so... I had an idea for a program that could upload a reverse shell payload to the server, but then realized that I'd probably need a reverse shell already to use it...so that's dumb

maybe a thing to setup a webserver and startup a socat listener

[stone kayak]

ask the question? 🙂 https://www.nohello.com/2013/01/please-dont-say-just-hello-in-chat.html

[magic falcon]

Short answer: don't use SQLite

[onyx merlin]

That's far from helpful

Sqlite is decent for smaller projects

[brazen eagle]

or locally stored DBs

it's heavily used in Android/iOS projects

[magic falcon]

That's fair. I've never had a positive experience using it; eventually every app I've worked on migrates to using a more robust database and it causes many problems

What's the usecase? And what's the problem you are getting?

[brazen eagle]

I see it used a lot for config storage

which is silly

[magic falcon]

There are backend problems - sometimes strings don't convert correctly

Honestly, best use for SQLite I've seen so far is CherryTree

Kratos, what's the issue you are running into? I'm more familiar with Postgres and MySQL, but I've also used SQLite several times

[magic falcon]

did you enable foreign key constraints?

[dry trench]

const { Console } = require('console');
const express = require('express');
const app = express();

app.set('port', process.env.PORT || 3000);
app.listen(port, () => {
Console.log(Listening on port ${port});
})

[cursive orchid]

when asking for programming help, remember to let us know what's happening vs what you expect to happen

include errors etc

[dry trench]

im making a auth

errors Error: Cannot find module 'express'
Require stack:

• C:\Users\Administrator\Desktop\Auth2\app.js

  }

thats the errors

i want it to say Listening on port ${port}

as you can see

[cursive orchid]

okay well that error means that express is not installed

[dry trench]

ok cool

[cursive orchid]

you need to install via whatever package manager you are using (probably npm i express)

[dry trench]

got it

lets see if it works

TypeError: process.env.PORT is not a function

umm

[cursive orchid]

yep

do you know much javascript?

[dry trench]

no wait i might fix it

[cursive orchid]

const { Console } = require('console');
const express = require('express');
const app = express();

app.set('port', process.env.PORT || 3000); // This line is the problem
app.listen(port, () => {
    Console.log(Listening on port ${port});
})

also, that's not how you want to be setting the variable for port

[dry trench]

ok

[cursive orchid]

also i have no idea what that Console module is

[dry trench]

someone said to use it

what is a Console module

[cursive orchid]

a typical basic express app looks like this

const express = require('express');
const app = express();

const PORT = 3000;

app.listen(PORT, () => {
    console.log(`Listening on port ${PORT}`);
})

you are bringing in a module called console, i suggest reviewing some javascript/node basics before jumping into creating express apps

[dry trench]

im making it for a app someone asked me to make a auth for it

[spiral wren]

You agreed to hammer down some nails without knowing how to use the hammer :)) You should do some nodejs and/or JavaScript specific materials. There are lots of free resources on YouTube, or if you're okay to spend some money, there's a Nodejs course on Udemy by Andrew Mead that is great

[lilac holly]

can someone explain this to me?

i got stuck on this code earlier, still havent completely figured it out

the '../..' part specially

i really cant understand

[true pumice]

@lilac holly No.

That is from a room

No hints until tomorrow @ 7pm.

(as per rule 13)

[lilac holly]

can someone explain in private then? i already completed the room but i didnt understand this code completely

the filters

got me a bit confused

[pearl zephyr]

But writeups are already out i guess🤔

[true pumice]

Are they?

[pearl zephyr]

Yeah

[true pumice]

That's v/ annoying

I guess it's fine if writeups are out

[lilac holly]

@pearl zephyr u can dm me if u want, pls 🙂

[pearl zephyr]

Also @lilac holly its strange how u completed the room without understanding how filters work

[true pumice]

I'm still not sure of the rules here.

[pearl zephyr]

I will explain here only

[lilac holly]

@pearl zephyr i already tried the ../.. thing but it didnt work

so i didnt really need to see this code to know

but when i saw it i thought it was a bit confusing

[pearl zephyr]

@true pumice i guess its fine to explain the code if writeups are available🤔

[true pumice]

I think you should explain it in #room-help

[pearl zephyr]

Ok

@lilac holly paste ur code snipet in #room-help

[digital dove]

What room were you working on?

[lilac holly]

none

[digital dove]

That's not a lot. 😄

[swift crown]

“Intro to python” room has been removed?

[foggy hazel]

Wydm?

[swift crown]

The python room

[foggy hazel]

No no, this is a different issue about programming sqlite

For some reason I can't get my table to have foreign keys

[stone kayak]

You can always do the python stuff in AoC 2?

[fathom idol]

Hi, I have managed to capture some Dot11Auth and EAPOL frames using sniff in scapy. I do not capture all of the frames, normally I get frames 2 and 4 of the EAPOL key frames, is there a way I can capture more. I understand scapy sniff can be a little slow to capture frames and packets

I was thinking an lfilter would be faster than checking the frames in the prn function, but I dont know myself

def parse_packets(packet, output):
    if packet.haslayer(Dot11Auth) or packet.haslayer(EAPOL):
        print("Saving frame")
        wrpcap(output, packet, append=True)
...snip...
 sniff(filter="", prn=lambda p: parse_packets(p, outpath), store=0, iface='wlan0mon')

guys i have a problem and idk what it is

[stone kayak]

ok then we cant help much sorry 😦

[safe oriole]

Hello guys , is there someone who is experienced with IDS systems and detection of web app attacks ?

[sharp coral]

im not terribly experienced but I do have a working IDS/IPS set-up for my homelab, what is your question?

[safe oriole]

which IDS system are you using ? i am wondering what approach should i use in order to detect for example XSS attack on my web app

maybe some kind of anomaly detection or ?

[sharp coral]

i've used an ELK stack, suricata, snort and splunk - splunk will be the easiest to get up and running

filter a search for access logs on the web server, probably filtering for POST requests - manually enumerate your webapp and look for likely vectors of attack and filter those points

then set up an alert in splunk for requests on that endpoint

suricata's eve logs are good for anomaly based detection too, can also be indexed by splunk

[magic falcon]

A "normal" build of SQLite doesn't support foreign key references. To make it work, you need to either re-compile your SQLite engine, or else download a version that has it enabled

[magic falcon]

Usually protection against that is done by a load balancer, WAF, or by the application itself

[safe oriole]

the thing is , i am building my own IDS from scratch. and i am trying to find some interesting approach to detecting theese web attack

[sharp coral]

detection not prevention juun

[magic falcon]

Droogy's solution is less what I would think of as being IDS and more being log analysis - my understanding of IDS is that its usually done in real time on layer 3

Firewall mfg (fortinet, ubiquity, cisco) all offer IDS options for their pricier appliances

[sharp coral]

well tbf there is no intrusion detection without logs to analyze

don't try and reinvent the wheel and build your own IDS, I mean i guess I would start with building some sort of front-end or even basic cgi-script that will essentially tail -f access.log

[foggy hazel]

I was using sqlite with python3 and just importing it

[safe oriole]

Its my bachelors thesis project 😄 what am i doing now is that i take the HTTP request and look for some suspicious input using REGEX but its obviously not enough

[magic falcon]

SQLite from where? are you doing this on windows or linux? i'm going to try to recreate your problem

[safe oriole]

so my question is , what is probabbly the best posible way to analyze theese logs

[sharp coral]

gotcha, this would be a good place to start, suricata rules contains malicious signatures, there are thousands upon thousands of these rules, you can incorporate the attack signatures into your own db and figure out an interesting way of indexing them maybe https://github.com/jpalanco/alienvault-ossim/blob/master/suricata-rules-default-open/rules/1.3.1/emerging.rules/emerging-web_client.rules

[magic falcon]

I haven't heard "the experts" use IDS in terms of a SIEM - happy to admit i'm pretty ignorant on SIEM terminology; i have heard networking people talk a LOT about IDS/IPS being done on their appliances. learning new things day by day

[safe oriole]

so basicly .. its all just regex with some extra steps ?

[sharp coral]

ahh okay yeah I hear ya, there is definitely a lot of blending between the terminology, they both work best when used together but a SIEM is the aggregate of all alerting and events, an IDS is just a little piece of the entire security posture

yup! hard to think of a better way when it comes to web-apps to filter for malicious activity than good ol regex

if it's for a thesis, you also may want to look into setting up a honeypot web-app on a VPS for some live data

[safe oriole]

yeah i am using DVWA for that purpose

i allready have some SQLi regex rules but i think its really easy to bypass them

for example if u try to catch ' order by 1 --

[sharp coral]

ahh having DVWA connected to the internet sounds like a really fun project 😄

[safe oriole]

u can still do ' or/asd/der by 1 --

[sharp coral]

gotcha, you can still use regex in that case to look for mutations and edge cases, thats why suricata is so damn good

[safe oriole]

i mean not on the internet 😄 its just my virtual network

do you have some reference please ?

[sharp coral]

ofc, i hate to be that guy but their documentation is actually rather good https://suricata.readthedocs.io/en/suricata-6.0.1/quickstart.html

[safe oriole]

its okay thanks 🙂 , and the bigest problem i am facing rn is that u can run XSS with every fcking html element according to this https://portswigger.net/web-security/cross-site-scripting/cheat-sheet

that will be a lot of work to create regex rules to catch everything

thats why i came here 😄

[sharp coral]

if you're focusing on XSS you might want to scrap DVWA and just build something custom specifically vulnerable to XSS and just hammer it

[magic falcon]

If its for school, your dept may have budget to help you out with buying some tools or hardware

[safe oriole]

i will probably take some inspiration from Suricata IDS

i just tought i was thinking wrong by using regex for this

anyways thank guys 🙂

[foggy hazel]

i did this on windows; i can dm you what i coded?

[swift crown]

Anyone have tried PTS preliminary programming

[magic falcon]

I'd rather you tell me what versions and the sourcing of your SQLite and python, first - code from earlier looked correct, and code won't matter if the db isn't enabled for what you want

[swift crown]

Have you tried

preliminary programming from INE

[magic falcon]

I don't know what that is.

[swift crown]

Ok

[magic falcon]

is that a bootcamp?

[lilac holly]

Hey @grave salmon , What are your thoughts algoexpert.io?

Is this is a good resource to learn programming?

[grave salmon]

🤷‍♂️ not familiar

[lilac holly]

Are you self taught or go to school?

[grave salmon]

semi-both.. taught myself a bunch but I did have classes on java, data structures and algorithms, python, javascript etc in uni

[lilac holly]

Niice, thanks for the insight my guy

[cursive orchid]

that's that youtuber's site isn't it

the one who worked for google or smth

[stone kayak]

I uuhhh

It's alright

he explains it poorly

[lilac holly]

That tech with Tim guy ?

What's the best and effective way to learn programming in your opinion? @stone kayak

[stone kayak]

make stuff

[magic falcon]

^^^ This. Pick a project, figure out how to solve all the problems for it

[lilac holly]

Okay then! I will build a website for my gfs new startup business

And an app!

Why does this AWS API Model take empty string & no list?

{
  "$schema": "http://json-schema.org/draft-04/schema#",
    "title": "lookup",
    "type": "object",
    "properties": {
        "Hash": {
            "type": ["string"]
        }
    },
    "required": ["Hash"]
}

I don't want it to accept when:

• String is empty
• Hash's value is not a list.

Currently this works (I don't want this to work as it's an empty string):

• {"Hash": ""}

These 2 do not work:

• {"Hash": []}
• {"Hash": 6}

Why does it execute on empty string which isn't in a list, but empty list doesn't execute?

How do I make it so it only works if the input is {Hash: ["Hello"]} and not empty string or a single string?

Thanks for any help you can provide 🙂

@sly breach 🥺 if you do AWS API stuff do you know? ❤️

[magic falcon]

Can you link to the docs?

[sly breach]

Only CLI

How much programming would I need to know in order to land a decent job ?

[hollow root]

hey bro you are solving room

[cursive orchid]

job as a what

[lilac holly]

Software engineer or developer

[cursive orchid]

you'll ideally want to know the language the job requires inside out

[brazen eagle]

An empty string is still a string and matches the schema?

[safe oriole]

no its my own project

Is there a way I can not do that? :))

Lol

{"Hash": ["Hello", "yes"]}``` fails too

[brazen eagle]

I'll have to look up JSON schemas

[hardy iris]

try this^

[stone kayak]

:((

[hardy iris]

🤔

[stone kayak]

Would be nice if AWS told you what that meant lol

[hardy iris]

i was playing around with aws and it worked tho

[stone kayak]

lemme try some json validators

ahhh

the comma

"name": { "type": "string" }, remove comma and it works

[hardy iris]

does it do what u need tho?

[stone kayak]

No :((

But thanks for trying!

These work:

{"Hash": []}
{"Hash": 6}
{"Hash": [9]}

[stone kayak]

I got it I think

that moment when you are sick of renaming files, that you make a python script that renames files for you xD

[brazen eagle]

that looks ok

[viral lance]

howdy yall anybody here knowledgeable with .c files help me out does the .c file need some sort of exit command at the end of the file what tells the compiled binary to stop and exit ?

[solar hull]

the program will exit once it returns from main (or exit(int) is called)

[sharp coral]

hey all, about a week ago I had a good kata-like problem, just wanted to share my solution, would def appreciate some input as I may adapt this program into some crunch-like utility

Prompt:
I forgot a WinRAR-archive password. I remember there was a name of someone from my (hypothetical) family: jake, melissa, oliver, emily.
I remember there was a year of birth of someone from my family: 1987, 1954, 1963.
I remember there was a symbol:
["!","@","#","$","%","&","*","-","=","_","+",".",","]
But I do not remember an order of these elements.
You have to find a list of all possible passwords, based on this information.

Addendum: You must also create some way that the user can create a custom list.

import itertools

names = ['jake', 'melissa', 'oliver', 'emily']
years = ['1987', '1954', '1963']
symbols = ['!','@','#','$','%','&','*','-','=','_','+','.',',']
all_lists = [a, names, symbols, years]
# user input list
a = []
# check if we have cmd line args
if len(sys.argv) > 1:
    # check that custom(-c) flag is set
    if sys.argv[1] == '-c':
        # size of list is 2nd cmd line arg
        list_size = int(sys.argv[2])
        for i in range(list_size):
            element = input('add to list: ')
            a.append(element)
else:
    pass
master_pass = []
# permy does all the heavy lifting
def permy(single):
    # itertools magic to iterate over combinations
    list_iterator = list(itertools.product(*single))
    # join together tuple elements to form a password
    final_list = [''.join(tups) for tups in list_iterator]
    # add each password to a master list
    for i in final_list:
        master_pass.append(i)

res = itertools.permutations(all_lists)
for x in res:
    permy(x)

with open('all_passwords.txt', 'w') as x:
    for password in master_pass:
        x.write(f'{password}\n')
# debug master list
#for i in master_pass:
#  print(i)

[true pumice]

The else statement is completely pointless at the start.

else:
    pass

all_lists = [a, names, symbols, years]
# user input list
a = []

a is defined after all_lists so this should result in an error when run in some IDE's.

[onyx merlin]

Why does a exist at all?

[true pumice]

It's for "user input" it seems

I would probably do:

try:
# check if we have cmd line args
  if len(sys.argv) > 1:
      a = []
      # check that custom(-c) flag is set
      if sys.argv[1] == '-c':
          # size of list is 2nd cmd line arg
          list_size = int(sys.argv[2])
          for i in range(list_size):
              element = input('add to list: ')
              a.append(element)

# user input list
  all_lists = [a, names, symbols, years]

except:
  all_lists = [names, symbols, years]

[onyx merlin]

Oh it's used there

[true pumice]

Mhm, I do not see why a was used before creation 🤔

[sharp coral]

oops thats totally my fault,all_lists should be initialized right before master_pass - was copy-pasting code blocks

the try except is a good idea, was thinking of a way to handle no user-input

i'm writing a python script that loads a json file and downloads images from the links in it

how do i use it as an arbitrary script?

like just provide the file as as argument so it can be used on any json file

[sharp coral]

python has a built-in json library, json already comes in a keyed value this works out nicely as values can be accessed like a dictionary. you can prompt for user input with input() and then use with...open to create a reader object and pull data from the json object or the user can specify on the command line and you parse that with argv

as for downloading images, requests module is the way to go

am i allowed to ask for help/guidance on this shopping cart i am trying to make? it is not school work but its still based around what i do in my classes. Just wanted to ask before posting. But at least i have created a few classes and functions in python for a very simple and basic online shopping cart. It is not supposed to use frameworks like django or flask, nor gui like tkinter. I have also created a html file, but what im currently struggling with is making the html file execute the functions in my python file
i can post the code if allowed to

[brazen eagle]

I assume your python is server-side

so you'll need to expose and call an api

usually via forms or javascript

[timid parcel]

well it practice based on assignments done in the past in the python course, so we have never had js, so its not for that

[sharp coral]

hmm sounds like you could maybe do something with cgi scripts if you need your code executed on the page?

feel free to post github link or something, not sure what code box limits are here, im assuming under ~50 lines is reasonable enough to not spam the server - should clarify with mod tho

[timid parcel]

yea okey, cheers! imma post it, and hope its okey

so this is the code i have this far at least. hope someone got some tips

[clear needle]

You could do it janky with a php shell exec

[timid parcel]

i think i was only allowed to use python and html tho:/ but ty for tip:)

[clear needle]

https://m.youtube.com/watch?v=8LEWb-eF8TE

[gusty crescent]

I have a python dictionary dict = { 'a' : '', 'b' : '1' } whose values I'm calling with first = dict['a']. Since every empty string evaluates False, I'm replacing it with a zero if not first: first = 0.

Is there a possibility to let a for loop do that for me, so I don't have to write the if statement for every variable?

[sharp coral]

for x in dict:
    if dict[x] == '':
        dict[x] = '0'

you can probably get fancy with dictionary comprehension but this is probably the easiest way to get that done

[true pumice]

*This code has been untested.

If you are working with dictionaries, I would recommend using .items() when iterating over them.

for key, val in dictionary.items():
  if not val:
    val[key] = '0'

I would also recommend, Droogy, when writing code to use variable names that hint towards what the variable's purpose is:)

[gusty crescent]

that didn't change the result, dict still contains {'a' : ''}

[gusty crescent]

same here, still the same final result

[true pumice]

I didn't test my version, gimme a sec to take a look ;)

[true pumice]

dictionary = { 'a' : '', 'b' : '1' }
dictionary1 = { k : '0' for k,v in dictionary.items() if not v }

print(dictionary)

dictionary = dictionary | dictionary1

print(dictionary)

Output:

{'a': '', 'b': '1'}
{'a': '0', 'b': '1'}

This way is much better although:

def function(dictionary):
    return { k : '0' for k,v in dictionary.items() if not v }

dictionary = { 'a' : '', 'b' : '1' }

dictionary = dictionary | function(dictionary)

print(dictionary)

Output:

{'a': '0', 'b': '1'}

@gusty crescent

There's probably an easier way but this works so 🤷‍♂️

[gusty crescent]

never change a running system 😄

Thank you! give me a minute to test it

Seems like computer says no, did I missspell something?

[true pumice]

Which version of python are you running?

[gusty crescent]

3.8.5

[true pumice]

Ah

That only works in 3.9

You would need to do something like:

dictionary = {**dictionary, **function(dictionary)} instead of dictionary = dictionary | function(dictionary)

I don't have 3.8 installed so you'll have to do some playing around :D

[gusty crescent]

Or I could just install 3.9 😄

and it works, thanks a lot 🙂

[true pumice]

No problem :D

[gusty crescent]

This does work for 3.8 btw 🙂

[true pumice]

Awesome !

[sharp coral]

weird, just tested

appreciate the tips jabba!

[true pumice]

It's always great to build good habits:)

[gusty crescent]

Huh odd, „but I swear it didn’t work when I tried“ cause now it works for me as well. And I even copied your code, so must’ve been a typo

[balmy flint]

Want to know how to remove the common elements with only the count of the another elements in a list
Lets say we have a list

b=[1, 2, 1]
the result which I need is [2, 1]```

Any help or tips !

[true pumice]

You want to remove duplicates?

[brazen eagle]

Looks like the complement

[balmy flint]

Not duplicate I mean the exact subtraction of list

[true pumice]

Uhh probably like

[brazen eagle]

Like a - b

[balmy flint]

Yes

[true pumice]

for item in list_one:
  if item in list_two:
    list_two.pop(item)

[brazen eagle]

Actually that would be like that in Kotlin...

[true pumice]

Actually

Which language

I presumed python lmao

[brazen eagle]

Looks like python

[balmy flint]

In python

Initially I tried with in operator but that doesn't work

[brazen eagle]

Hmm

If an item is in B but not A, do we include it?

[balmy flint]

So we taking the bigger list as first and removing the elements from second ?

[brazen eagle]

Basically but that's not terribly efficient

[true pumice]

Script:

a=[1, 2, 1, 2, 1]
b=[1, 2, 1]

for item in b:
  if item in a:
      a.remove(item)

print(a)
print(b)

Output:

[2, 1]
[1, 2, 1]

[brazen eagle]

What if b=[1,2,1,3]

[balmy flint]

We hav to exactly remove the common and print the entire remaining elements

[brazen eagle]

From both lists?

[true pumice]

I'm honestly confused

[balmy flint]

Yes

[true pumice]

Oh you're trying to compare the lists

[brazen eagle]

You need the complement of the intersection

[balmy flint]

I don't understand this sorry what does it mean

[brazen eagle]

Or the difference

Intersect is the set in common

Complement is the opposite

[balmy flint]

Just I need the difference

[true pumice]

I'm confused

Do you want the elements that are in both lists

[balmy flint]

Am I confusing !

[true pumice]

Or remove the common elements from both lists

[brazen eagle]

You need (A-B)+(B-A)

[true pumice]

a=[1, 2, 1, 2, 1]
b=[1, 2, 1]

for item in b:
  if item in a:
    print(item)

Output:

1
2
1

[brazen eagle]

Apparently sets work but I don't know if they handle duplicates in python

[true pumice]

Sets changed since python 2 so I don't use them lmao

[brazen eagle]

https://stackoverflow.com/questions/6486450/python-compute-list-difference

[balmy flint]

Ok
I'm expecting like this
A = [1 2 3 1 2 3 1]
B = [ 1 2 3 1]
The result I need is [ 2 3 1]

[brazen eagle]

Yay google

[balmy flint]

Ok 👍

[true pumice]

a = [1, 2, 3, 1, 2, 3, 1]
b = [1, 2, 3, 1]

temp = []

for item in b:
  if item in a:
    if item not in temp:
      print(item)
      temp.append(item)

Output:

1
2
3

temp = 1, 2, 3

[brazen eagle]

Would that work if the lists were inverses?

IE b >a

[true pumice]

Seems to

a = [1, 2, 3, 1, 2, 3, 1]
b = [1, 2, 3, 1]

temp = []

for item in a:
  if item in b:
    if item not in temp:
      print(item)
      temp.append(item)

1
2
3
>>> print(temp)
[1, 2, 3]
>>> 

[brazen eagle]

Seems a bit odd but it's probably a pathological test case

That's finding the set of the intersection

Try with a = [1,2,3,4]; b = [2,5]

[balmy flint]

So we have to set the two lists and finding the difference is it!? But what if I need the elements which is not in A but in B ..just curious to know how to tackle

[brazen eagle]

That's why I said (A - B) + (B - A)

[balmy flint]

Oh noted now tks...

[brazen eagle]

You can also use (A + B) - (A intersect B)

[balmy flint]

Actually I am trying to solve a problem where we have to divide the given list into 2 halves irrespective of list length provided that the average of two lists are equal.. provided that first list have to have the first element in the given list...😀

[brazen eagle]

Hang on a sec while I parse that

[vernal vigil]

intresting problem , imma try it too

[brazen eagle]

So assumes sets S, A, B. S[0] is an element of A. Mean(A) = Mean(B)

[balmy flint]

Shall I post the screenshot ?

Of the question

[brazen eagle]

I think that mean(S) = mean(A) = mean(B) applies no?

[balmy flint]

Yeah that's it

Its a type of combinations and stuffs

[brazen eagle]

It's set theory, partly

[vernal vigil]

wait is it set of sets?

[brazen eagle]

Set can mean list here I think

[vernal vigil]

so

[magic falcon]

sets in py3 ignore duplicates

[true pumice]

Is this binary search?

[brazen eagle]

No

[balmy flint]

Ok It's midnight for me now Ill catch u morning guys...take care have a great day

[brazen eagle]

You can find the taeget mean easily

Target too

[vernal vigil]

i have seen this problem

[magic falcon]

this is a pretty common algorithms homework problem

[brazen eagle]

It's probable

I'd probably start by sorting the list

Then pick min, max, min,... Until I reach the target mean

Probably not reliable though

Seems to work for the examples though

[vernal vigil]

u take sum of all the elements in array,
you traverse the array and add elements one by one for subset1
and u subtract it from the total sum say its subset2
then you check if the average for both are same, then volla u got it(most likely)

[surreal bronze]

Ooo

[stone kayak]

I just found a neat way to add threading to a program without knowing what threading is.

1. Shuffle the input
2. Run multiple programs
3. Hope they never touch the same item at the same time, it's shuffled and if there's many items it'll be okay

Wow it's actually working, I'm a genius

[brazen eagle]

BOGOthreading?

[magic falcon]

i feel kind of sick at that approach to concurrency

[stone kayak]

Yes well it's working

Hi, do anyone knows of a website to learn programming by completing challenges?

I wanna learn C as a beginner, but also I’m very into bash after the bash scripting room on THM. So if you know of just a list of tasks a beginner can complete, and learn programming along with it, would be very helpful

[solar hull]

Hackerrank, maybe?

[stone kayak]

check pins

there's loads

[bright delta]

@lilac holly there's a good intro to C course on udemy

"C programming for beginners, master the C language"

[lilac holly]

Thank you all, I’ll check the resources!

[tribal smelt]

anyone good with ajax/php?

[bright delta]

imo learning C is a bit different than other languages

ie, if you wanted to learn bash/python/ruby, I'd say, just come up with a project/go to hackerrank and go through them. With C, I think you should get a good overview of how it deals with memory/pointers/data types etc. it's a different paradigm

then once you have gone through a lengthy tutorial, then move to a project

[lilac holly]

I have basic assembly knowledge as I knew it’s what C is based on. Of course I don’t know everything so I wanna dig deep into it. I have some ideas of projects, so for now I’m gonna study it as much as I can

And thanks for the overview

[distant shard]

What type error?

Oh

Yeah, gotta convert it to a string with str()

[true pumice]

I'm confused on the task exactly?

[distant shard]

Find out whatever number 2^1000 is, loop over all the digits and sum them

[glass cape]

are you sure so then i have to use for loop on string

[distant shard]

Yeah

Convert it to a string

And then you can loop over it with a for-in loop

[glass cape]

i was thinking of using pow function

[distant shard]

Well yeah

You gotta calculate 2^1000, store that in a variable, convert it to a string and then you can loop over the digits in the string with a for-in loop

[true pumice]

Ah I see now.

[glass cape]

got it thanks for your help

[glass cape]

can i dm ??

[true pumice]

(BTW you don't have to store 2**1000 in a variable)

[distant shard]

Yeah but I figured to keep it straight-forward instead of onelining it

@glass cape Sure

[true pumice]

Just unnecessary variable assignment

Why store it in a variable when you can directly iterate over it in the for loop?

[distant shard]

I'm just breaking it down

[true pumice]

??

[distant shard]

I found it easier to learn it by breaking it down into more lines

And then after getting it working, seeing how I could rewrite it in a shorter form, such as removing unnecessary variables.

I'm trying to iterate over two excel tables at the same time using openpyxl (in this case both tables are on the same sheet) and paste a value of table A to the corresponding row of table B. I've tried this

for row in ws.iter_rows(min_row=2, max_row=379):
    date_dissection = str(ws.cell(row=current_row, column=3).value)[:10]
    nerve_dissection = ws.cell(row=current_row, column=6).value
    id = ws.cell(row=current_row, column=1).value
    current_line = 2

    for line in ws.iter_rows(min_row=385, max_row=617):
        date_dmg = str(ws.cell(row=current_line, column=3).value)[:10]
        number_dmg = ws.cell(row=current_line, column=7).value

        if date_dmg == date_dissection and number_dmg == nerve_dissection:
            ws.cell(row=current_line, column=1).value = id
        current_line +=1
    
    current_row +=1

But its not doing anything or hangs. Also tried having the tables split to different worksheets, but with the same outcome.

[sharp coral]

dumb question but is this for a personal project? sounds like something you do with VLOOKUP if you just need a quick and dirty way of mapping values between tables

[gusty crescent]

yes it is, I'm a student so nothing I'd get paid for. I just like python and to automate stuff with it

[true pumice]

VLOOKUP function only works if the value is in the left column of table A so if it is then just use a VLOOKUP and then retrieve the data with python CSV

If anyone want a kickstart into writing their own shellcode, I've made a playground that has the following features:

• compiles .c both to 32 and 64 bit (filename and filename64 respectively)
• compiles .asm to 32 bit binaries
• compiles .asm64 to 64 bit binaries
• provides a shellcode runner that works for 32 and 64 bit
• example shellcode for 32 and 64 bit
• make raw will print the shellcodes as \x string

./bin/shellcoderun (echo -n -e (make raw | grep -v printf | grep -w 'shell' | awk '{print $2}' -))
Simply change the 'shell' to the name of your binary!

Anyone have any experience with Vue JS/Axios and POST requests and willing to have a quick look at something? Not looking for someone to write code for me, as my logic works completely fine on my local machine (which leads me to think one of the server admins has potentially made a change), but would appreciate a more experienced eye to be casted over an issue i'm having.

[brazen eagle]

did you take latency into account with your promises?

[sweet pike]

I worked around the issue now, i used Fetch in async rather than Axios. I'm not entirely sure what was at fault specifically, but the fact it was working on my local instance and not the server itself (and the extra data it was returning at the top of the response) was strange. My data was being received, it just wasn't in a format i could access due to the additional data. Working with Fetch has circumvented that for now.

I tried a plethora of content-types and accept headers in order to fix it, but i know the issue was with Axios in the process, as debugging through each step the data was as expected right until the point it was returned into Axios.

[vernal vigil]

just a simple question:

for statement{
conditional statement #1{
conditional statement #2{
}
}
}

For this the time complexity should be n + 1 +1 , correct?

== O(n)

well nvm, problem seems to be the competition server.

[brazen eagle]

Should be O(n)

[plain fog]

Condition such IF is in linear time so it is assumed constant time. So there is only one loop so it means O(n)

[tribal smelt]

    console.log("Is it even loading?");
  $('#submitLogin').on('submit', function( e ) {

    var form = $('#login form');
    console.log("Form logged");
    
    $.ajax({
        url: 'authenticate.php',
        type: 'POST',
        // Get Form Data
        data: form.serialize(),

            console.log("Didn't Work");
        }

You can also try tutorialspoint, they have a LOT of content on many subjects... but the content is hit or miss. https://www.tutorialspoint.com/assembly_programming/index.htm

alright thanks!

[gray ledge]

has anybody worked with the google sheets api?

[tribal smelt]

anyone here able to help me understand some documentation for a payment gate that I'm attempting to implement?

[distant shard]

I've been going through screenshots that my co-worker and I would take whenever we encountered "not-so-good" code. I found this beauty just now.

Or this beautiful memory leak that somehow made it past review. It would completely clog up your RAM within a couple minutes.

I'm trying to modify an exploit for a machine on tryhackme. The problem is that there are two authentication methods. How can I stay authenticated and do the next authentication. The first one is a basic auth the next authentication can be done via the exploit itself. I need to find a way to persist the basic auth and then continue with the rest of the exploit. Can someone help pls?

[brazen eagle]

There's a way to get basic auth in the url

[sour apex]

I used the request module to login and it works fine..but the session is not persistent. It closes as soon as the next line is executed

[brazen eagle]

That it intended

It's actually once a minute

[brisk sedge]

Found an interesting, and rather short, whitepaper about using polyglot code to potentially evade antivirus software. I found it rather interesting since the author referenced a whitespace esoteric programming language (Jaws) to inject code into different types of files without disrupting their behavior while still being parseable as their intended purpose. I thought someone else here might also find it an interesting read. 🙂

Hello

[worldly cape]

Does anyone know html/css

[surreal bronze]

Yes

What can we help you with

[vernal vigil]

Ask your question mate :0

[distant shard]

@gray ledge Late to the party but I liked this as well for x86 ASM
https://en.wikibooks.org/wiki/X86_Assembly/

[dark harness]

so i want to start programming and coading any ideas

[surreal bronze]

check pins

Has anyone had any luck getting a GDB plugin to work with Ghidra?

[radiant coyote]

Does anyone have a good resource for Python pen-testing scripts or programs? I'm in the process of learning Python as my first language and thought it'd be helpful to dissect other programs to see what types of things are possible.

[radiant coyote]

@tidal panther thanks for that. I'll start digging through some code right away 😉

[tidal panther]

there is also the book but the book is python 2

[radiant coyote]

I'll definitely look into that too. My library keeps growing the more I want to know. My son will have an awesome collection to learn from once he can understand it all.

[feral moss]

Hello. I am about to learn python programming and i would like to know what is the best IDE you might recommend? I see PyCharm is ok 🙂

[magic falcon]

Pycharm is pretty good; it's what i use for my own coding. When i'm coding for work, I have a set of VIM plugins

largely because it is easier to SSH in than try to develop that codebase locally

[true pumice]

I would recommend downloading a bunch of IDEs and seeing which one you find is best fit; at the end of the day it’s what suits your needs.

[surreal bronze]

PyCharm is good but I find it's pretty heavy and takes up a lot more resources then other IDEs

I just use sublime text with my terminal

Its a text editor but it's great either way

[tribal smelt]

Can anyone look over a javascript and tell me why it isn't working

[bitter field]

I can, but Im no expert

[tribal smelt]

Well, you're gonna hate this as much as I do, can I dm you further information, so the link?

@bitter field

[bitter field]

sure

[tribal smelt]

[radiant coyote]

If you're a current student with the appropriate email address, you can get all of the JetBrains products for free.

[sharp coral]

if you're a student you should also apply for the github student developer's pack, its insane how much stuff you get - at least a thousand dollars worth of access to various software suites and stuff

[tribal smelt]

damn it javascript.

=[

Switch cases in Python are coming https://github.com/gvanrossum/patma/blob/master/README.md#tutorial

[feral pollen]

Heyy i"m start learning network fundanentals

I want follow network pentest

So do you have some site for practice? Or resources for this major

[stone kayak]

#resources

[stone kayak]

For system design interviews (other than practice questions) I made a table comparing a bunch of technologies (rabbitMQ vs Kafka etc etc) might be helpful 🙂

[mental storm]

some programming lunguages for pentesters

?

[onyx merlin]

Python, powershell, bash, C#

nim

only nim

always nim

nim solves all problems

[remote echo]

What's nim

[eternal spindle]

Who is nim?

[stone kayak]

nim is actually quite good imo

[tulip sail]

Loving Nim

[gray ledge]

i think that autocorrected from nano

[stone kayak]

https://nim-lang.org/

[gray ledge]

WHY DID I READ THAT AS VIM

im going crazy

[tidal panther]

secret of nim

[brazen eagle]

Compiles to JavaScript, gods help us all

[tulip sail]

Fortunately it doesn't need to do that

[brazen eagle]

Their odd numbers iterator example is inefficient.

Better to return x + x + 1 for all x in positive integers

You can do 2*x + 1 as well though the compiler might optimize that. But avoiding division is probably for the best, though %2 can be replace with &1

Ok I'm done

Actually... (x << 1) + 1 is probably best perf wise

[stone kayak]

The bitwise &1 is one of my fave tricks for checking odd numbers. Idk if it's faster but in code interviews they go "woah you know bit operators????"

[brazen eagle]

Definitely faster than modulo

Compiler might be smart enough to optimize that though

Dividing is hard

Adding is easy

Subtracting is just adding

Multiplying is a bit harder than adding but easier than dividing

[onyx merlin]

Bee did you see us adding one to stuff the other day?

[wheat forge]

damn I can't send images in here

[brazen eagle]

Verify

[wheat forge]

is there any way that I can?

[wheat forge]

oh thanks

[brazen eagle]

Jumping is relatively expensive in systems as well so avoiding conditionals is good

[wheat forge]

they compile to the same thing

[brazen eagle]

Smart compiler

Looks like it's doing the add actually

[wheat forge]

interestingly these don't

yeah

[brazen eagle]

Yeah ok I can see why

The add is probably faster

[wheat forge]

although this optimises to just return 0

[brazen eagle]

Shift registers need a clock cycle

[wheat forge]

nice

this optimises to a shift

[brazen eagle]

Ah mod 2 is doing a shift right
