programming

[remote echo]

Instead it uses ownership model to determine lifetime of something and then drop it once it's out of scope ( or when we call drop explicitly)

as the crates ecosystem and dependency management in Rust in extremely easy, it can get away with std library being minimal!

[surreal bronze]

https://devclass.com/2023/01/18/jetbrains-survey-developers-91-male-73-experience-burnout-more-liking-rust-and-go/

[magic falcon]

It claims it doesn't, but lifecycle behavior of variables once it has left scope doesn't clean up memory the way I would expect. Behavior of memory cleanup, even using drop, looks an awful lot like how Java handles GC.

[remote echo]

what's the way you expect? It does clear up memory, otherwise it will be memory leak. Also, can u provide a example as well

[magic falcon]

compile with debug, throw a breakpoint after the drop. Do a memory dump of the process, memory is still marked as allocated and active and contains the data

[remote echo]

are you sure that breakpoint is after drop has executed?

[magic falcon]

Does drop have some sort of undocumented built-in async functionality?

[remote echo]

? don't think so

https://doc.rust-lang.org/std/mem/fn.drop.html you can also explicitly drop a value

[brazen eagle]

Java does reference counting IIRC

but the GC is pretty magic

[magic falcon]

Right, but even when references are are 0 (equivalent to strong pointer with zero references in C++) the java GC doesn't actually deallocate until it decides too, and calling the GC may not force the collection to take place

[brazen eagle]

yeah, hence the magic

well, Ok, it'll try to run the GC when it get a lull in the cpu

[magic falcon]

I'm just surprised that it i was seeing similar behavior in rust, which doesn't explicitly say it but I think implies that the memory management behavior is different

[brazen eagle]

at least the recent versions aren't too heavily impacted perf-wise by the GC

[brazen eagle]

yeah not sure what rust's memory model is. It doesn't have a runtime, so there may be reference counting, but it's not quite like java's GC

[magic falcon]

It's supposed to be strictly scoped, but when destructors get called doesn't seem to reflect properly in a memory dump of the paused executable

[brazen eagle]

yeah but I'm assuming it's still deterministic

[magic falcon]

It ought to be, I agree

[brazen eagle]

arg why is my ssh not working...bloody kickstart

[magic falcon]

kek, did you give it the right pubkey?

[brazen eagle]

yeah but I'm being a bit dumb

gave it the right pubkey but I may not have put it in the right place

[magic falcon]

i always screw up kickstarts as well

[brazen eagle]

it's a bit wierd because it mounts the disk and seems to do a chroot in post

[magic falcon]

that doesn't seem that odd - unless it's leaving the chroot as the default environment after the install is finished

then it's weird and it's broken

[brazen eagle]

I dunno

ssh server is being installed at least

ok I dunno what I did but it works now...

bloody aws and their bloody requirements for bloody ancient systems

stuck with a 4.18 kernel because they only thing that supports something more modern is ubuntu

[magic falcon]

gross

good luck with that

i think even rhel 8 and 9 are on 5.x kernels now

[brazen eagle]

waiting after AL2022

[magic falcon]

for sure fedora is

[brazen eagle]

CentOS 8 Stream is on 4.18

so I don't think RHEL8 is

CentOS 9-Stream doesn't import

[magic falcon]

let me double check

f36 is on 6.1

[brazen eagle]

f37 as well

[magic falcon]

oh, you're right. RHEL8 is 4.18

[brazen eagle]

yeah I'm installing it now

9 is on 5.15 I think

[quick void]

Hey, I've been working with SQL on w3schools in school, but I'd like to have a fully working db instead of having to write my inputs into a notepad. Is there a way to install a db software with a working db onto a usb drive so I can just plug it into any windows computer and work on it?

[cold coyote]

https://www.sqlite.org/index.html

[magic falcon]

Run a virtual machine; postgresql, mysql, maria are all very easy to install on linux.

[quick void]

I don't have access or time to install vms on school computers.

[magic falcon]

Can you install a VM on your personal computer? A properly set up school network will not allow you to run programs from a USB drive.

[quick void]

Yes I can plug a usb drive into a school pc, my personal computer is not the problem, I need the db to be portable so it will be the same db whether I plug my usb into my personal pc or a school pc.

[cold coyote]

You can setup SQL also and the move the DB into the usb drive then mount the DB but that is not easy

If you really need to use SQL but very heavy on memory

[magic falcon]

I wouldn't recommend doing that until after you learn the internals of how your db engine of choice behaves. Plugging in the USB isn't the problem, it's running an executable from that pendrive that may violate your schools policy with respect to unapproved software.

BEFORE YOU DO THIS, please go talk to the school IT staff and learn what the policy actually is. I have heard of students being suspended or expelled for violating IT policy this way.

[quick void]

There is league of legends and cs 1.6 on almost every computer. I don't think there is any policy on usb drives.

[magic falcon]

Learn the policy. The games may be approved, but bringing unapproved software in could be bad for you. Talk to the IT team and learn what the policy is.

[cold coyote]

Maybe they have a golden image to rebuild all PC when stuff goes wrong 😂

[quick void]

There is no policy and no IT team. Every once in a while you will find sillygoose installed on some computer, I was just trying to find out if it is possible to have an offline portable plug in db. If not, I'm content with it, if yes, I'll try to see if I can make it work.

[cold coyote]

I have changed the format file and my colleague what to play my file as was mentioned that was a game. It was very fun 🤩 that was 25 years ago, time of Netscape browsing 😂

[signal crater]

there is xampp which is an all in one package with database etc. can just be installed and run

[brazen eagle]

they're easily containerized as well

[magic falcon]

Even on windows! Even if podman wants to use WSL as the backend for some reason

[brazen eagle]

I mean it's easier than hyper-v

docker uses WSL as a backend as well

[magic falcon]

If I could configure podman on windows to use hyperv I would give it a try - same with using another hypervisor backend

[brazen eagle]

still need a kernel backing the containers

[magic falcon]

does it? that makes me kind of sick, after using docker, podman, lxc on centos for so long

[brazen eagle]

I mean it's all cgroups and namespace magic anyways

[magic falcon]

that's true; i'm more irritated at the lack of virt options for containers on windows

[brazen eagle]

docker has windows containers

[magic falcon]

yeah

[brazen eagle]

but yeah I've never used them

[magic falcon]

but i have zero interest in using them for the foreseeable future

pretty much anything i would want to run on a host i already know on linux or the equivalent runs better

[brazen eagle]

Yeah

[surreal bronze]

async function loadNames() {

Not sure what "end of input" means

Any ideas would be great

[brazen eagle]

Which one is line 22?

Also the response is likely empty or not json

[surreal bronze]

const names = await response.json();

how can I check if the response is empty

[brazen eagle]

Are there any other headers on the browser?

What happens in curl?

[surreal bronze]

Yup

response.text gives nothing

eh, change it to http with a different site and it worked

Oh PowerShell aliases curl to invoke-webrequest

[bronze mist]

I need to code a ROT13 decoder in js

[magic falcon]

for an assignment?

[bronze mist]

no, for a project

[magic falcon]

what kind of project?

[bronze mist]

caesar cipher

encoder/decoder

and i chose rot13

[minor zealot]

There should be plenty of resources online. Break it down in small chunks what needs to be done and research for it.

[paper bolt]

does anyone have google api experience? I have a security question regarding OAuth 2.0 and the safety of an app deployed for production

idea is I don't want to share a client_secrets.json.

[hollow sorrel]

This should be easy enough. Do it manually first then try to automate it with code

[brazen eagle]

Sounds like homework

Though that might be an interesting coding test

[lilac holly]

Would it be beneficial to learn Javascript/typescript while studying cyber security?

I want to learn a language and I'm leaning towards python

However, I also discovered the game "screeps" so I'm curious if learning typescript/Javascript is worth it

TLDR: is learning typescript a good way to learning programming in the cyber security world?

[onyx merlin]

Javascript, at least for web, is quite important.
Not sure if I'd recommend learning it fully rather than getting just the basics down, but it can't hurt

[brazen eagle]

Any language will help get the basics down. The rest is mostly learning the syntax

[lilac holly]

python3 and javascript is good

[magic falcon]

It doesn't really matter which language you pick; my recommendation is to pick a language that has a common usage with the other goals you have.

[lilac holly]

Ok cool. Maybe I will learn Javascript too so I can also play screeps

[jolly lotus]

Started off with python myself. Later went on to learn java, now doing quite a bit C++

[vapid cloak]

As someone who is not a masochist, I find the fact that I am endeavoring to learn C and code in it ironic. Ha. It’s only been a matter of days since I started, and am already getting the vibe, “this is how we used to do things the hard way” lmao. Like, I’m simulating OOP using structs and function pointers, and while I feel special (jk) I’m beginning to realize the major difference in effort this requires…. 🧐

[magic falcon]

If you are trying to simulate OOP encapsulation, that is not the way to go about it. C is as close to bare metal as most programmers get, it's not really about doing it "the hard way" it's about understanding the high level concepts associated with computer organization and architecture.

[wraith hearth]

So In Learn Rust Room There's Question: What's the smallest sized signed integer in rust? Answer: i16, Wouldnt Smallest Be i8?

[lilac holly]

Are you working on any interesting projects? Would love to hear..

[vapid cloak]

Despite the pain, I like the OOP simulation due to its organization. Being able to associate functions with structs and call them using dot or arrow syntax versus just having a naming convention for functions such as Class_method definitely appeals to me more. However if I was concerned about memory usage, I would probably use straight functions to reduce overhead.

[brazen eagle]

A couple bytes overhead is a small price to pay for proper readability

[clear lodge]

tech interview tomorrow 😬

the only thing I know about the role is "Vue.js, SCSS"

lmao

[vapid cloak]

Yeah I didn’t consider the actual usage. Even with embedded systems it’s probably not even a concern. I’m new to this space (systems programming) so I was speculative in my answer.

[brazen eagle]

How precise

[clear lodge]

the other keywords were "high pressure"

this is very promising

hahaha

but if I get the role I'm settled not to have to do any business/sales anymore for the next 4-5 months

so sign me up 8)

[chrome carbon]

Why do companies insist on bragging about having a terrible workplace? "High pressure" sounds awful!

[brazen eagle]

It really does, it's like the 10x bs as well

[peak cosmos]

Someone know how to use a ListView on visual C#?

[clear lodge]

I think its a warning rather than a brag. But Id like to know what kiwis think 'high pressure' is because things are generally pretty laid back here compared to other places. So maybe its just regular pressure, hehe

[peak cosmos]

❤️

When a user press "Aggiungi", the price should be added to the ListBox

[clear lodge]

You posted that question 10 mins ago, no need to bump it bera

[brazen eagle]

Have you read the docs?

There's probably some sample code

[clear lodge]

I think that went pretty well 🙂

just might get outcompeted by more experienced dev in interviews coming up but the interview was good I think

[clear lodge]

they had not really had time to look at the project I made over the weekend lmao. I put in like 12 hours a day 😄 but its cool. They appreciated it tho, haha

[wooden gale]

i want a base thing related to python can anyone help me!!

[brazen eagle]

just ask the question, please

[wooden gale]

can you please dm

[brazen eagle]

not really

[wooden gale]

i cant even put the file here

[brazen eagle]

what's the question? you may add the relevent error messages and code snippets using the code blocks (```)

[wooden gale]

i want to run a line in python file like - eg python file.py > what is the code > we typed the code > and the code wants to replace the current line and input the new line we typed

[magic falcon]

can you reword your question and example? What you're trying to do is not clear.

[wooden gale]

i want the python file to ask me what to put in number line or 11th line

[magic falcon]

of what?

There is no reason to DM me.

At least about this problem.

[wooden gale]

cuz i dont know a single thing about python'

if u can come dm i can sent the file and u can edit it and sent me

[brazen eagle]

we won't do your homework for you

[wooden gale]

hahah brw just fuck of

[true pumice]

Hah, homie really got upset because you wouldn't do his homework

[brazen eagle]

¯_(ツ)_/¯

[wooden gale]

yup cuz they didnt evn tell what to do ,or i think they didnt understand what i try to explain so showing the file is the better thing i think and they cant do that also

[brazen eagle]

let's not say anything we'll regret here

[magic falcon]

You sure about that?

[brazen eagle]

knowing how to formulate a question clearly and concisely is an important skill to learn

[wooden gale]

sorry brw my native language is not english

hope you understand

[brazen eagle]

I did say you may post code snippets using code blocks

like so

but we generally don't help with homework assignments, as that's usually considered cheating

[true pumice]

I understand you are struggling, but the purpose of homework is so that you can understand the topic. If you cannot explain the purpose of the program, there is no point with showing us the code is because we are not going to do it for you.

If it is homework and you are struggling, please speak to your teacher.

[wooden gale]

guys plz its not campus homework and stuff

i trying to make a simple tool that will help me really good in future

[true pumice]

Well, once again, there is no point in taking advantage of our knowledge. You need to learn Python and do it yourself

[onyx merlin]

You will help yourself much more by learning what to do.

[wooden gale]

the tool is working perfectly good but i need it to handle more easilt like - python3 file.py > and the tool wants to ask us what is think thats put in that line

[brazen eagle]

have you looked at the docs?

[wooden gale]

you just save your knowledge brw i dont want it i just asked a help

[brazen eagle]

I think I'm starting to understand what you want, but I can't be sure

[wooden gale]

😪 finally someone

[brazen eagle]

still can't help, because I've no idea what you're actually trying to achieve

[wooden gale]

i think its related to some input flag

but dont know how to use it

its ok

bye

[brazen eagle]

recommend you read the docs

but aside from that your problem statement is really not clear

[wooden gale]

yrah its okey brw , let me try once more the AI

hope that gonna help me

we humans are full of toxic , going to over soon

[brazen eagle]

not sure how the AI will help with such a muddled question, but ok

[wooden gale]

its already helped me to give me wonderfull tool

i just want to makes it easy for handle

its a easy one but for me its really good cuz i cant study the full python language and create a tool today

[tulip sail]

[magic falcon]

This was our reaction too.

[brazen eagle]

what a strange person

[tall beacon]

what have i just read lol

[gentle seal]

💀

[brazen eagle]

not entirely sure, but above quote summarizes it nicely

Chatgpt be really cool, i would hate if Microsoft would charge 200 bucks for 100% functionality 💀

[ornate tinsel]

Is there a way to rename a Linux file without using the rename syscall ?

[inland hazel]

hmmm

[lilac holly]

isn’t the command mv

I don’t know what you mean by rename syscall

you can say

mv file.txt file1.txt

[ornate tinsel]

yes but the mv command uses the rename syscall under the hood

[true pumice]

https://stackoverflow.com/questions/26970602/is-there-a-way-to-change-file-name-without-using-rename-system-call

Good day im lost here, I am doing a class Python for Cybersecurity through Cengage
not sure what operation I am missing when I get the correct answer

x= 3*(9 - 2) + (24/(6/3))*3 print (x)

[true pumice]

Can you post the instructions?

[shadow pebble]

@true pumice

[true pumice]

Is this for schoolwork?

@paper timber C'mon dude

[paper timber]

Its Cengage

Its literally a course or something

[true pumice]

And you don't think their school could have asked them to complete xyz?

Also giving them the answer teaches them nothing.

[paper timber]

Oh im sry 🙂

[shadow pebble]

im just confused on how i arrive at the right answer but it says i am missing an operator

i can put it in VB and it gives me no errors 🤷🏿‍♂️

[true pumice]

It doesn't say there was an error

[brazen eagle]

gods damnit Quarkus really works a lot better with Java

[brazen eagle]

one of the tests are failing

[true pumice]

Yes but that’s not an error, the code isn’t erroring, the test is raising an exception, hence why you can’t open it in a normal interpreter and run the same code

[brazen eagle]

May have misunderstood you are correct on that front, but I'd also argue a non-passing test is also an error 😉

Test is probably poorly coded though

These educational platforms aren't always the best

[final juniper]

could it be it was expecting you to flip 24/6/3 to 24*3/6 ?

[shadow pebble]

@final juniper the output checks out , i hate cengage its either their way or you will get an error

[final juniper]

the output result is the same, but it says that you haven't used their intended operators, and i think that's the only one that can change

I agree that the test should've expected that tho, but I had similar cases on codecademy ^^, it's obvious that they can't foresee any possible way to do stuff

[shadow pebble]

ok figured it out... its (3 * (9-2) + ((24 / (6 / 3)) * 3))

[covert jungle]

Hei, im currently learning about regular expressions and kinda stuck on one of the questions.
Questions: "Match all of the following filenames: ab0001, bb0000, abc1000, cba0110, c0000 (don't use a metacharacter)".

I have currently verified that this works: [abc0-1] , [abc]*[0-1]
But none of this is correct solution. Wondering if i missed some key concept and would appreciate some help.

[brazen eagle]

That doesn't look like it'll match tbh

[covert jungle]

Hehe, might be. But at least i get all marked when i use: https://regexr.com/

[brazen eagle]

Yeah but it's probably matching individual letters

Not the whole words

Think about what the question wants you to match

Are there any patterns you can abuse?

[covert jungle]

Yeh that make sence. I was thinking more like [abc] must be correct cause it will automatically get all the combinations.

but then im getting stuck on next part

0 and 1

[brazen eagle]

Yeah that's probably part of the regex

But [abc] will only match one character

Build up the expression step by step

[covert jungle]

For what i can see it will feks do this: " [abc] will match the string abc, but also cba and ca" . i might be wrong, but that is how i was looking at it before atleast

[brazen eagle]

[abc] will match an a, b, or c

You may also use a range, [a-c] will be the same

But you're on the right track

[covert jungle]

im so comfused, hehe

need to think for a while on that one

[brazen eagle]

The square brackets define a class of characters to match.

i.e. I want this next character to match one of those specified

So if you want to match more than one character with that class, you'll need to specify that

[covert jungle]

So i should use a "multiplier" like feks + or * ?

or as example say {0, } somehting

[magic falcon]

Throwing stuff at the wall will be way less effective and meaningful than understanding the definition of metachar, as the task suggests

[brazen eagle]

* means match zero or more of the preceding. + means match one or more

The task also says to not use metachars

[covert jungle]

[a-c0-1] is somehting that comes to mind

[brazen eagle]

Regexr should explain what the expression does though

[covert jungle]

but that is same pattern as before right

[brazen eagle]

Why 0-1?

Look at what you're expected to match, and deduce a pattern from there

[covert jungle]

Thank you so far, need to do some thinking here. Gonna read all chapters one more time

[brazen eagle]

Take notes

[vapid cloak]

You’re right juun! I’ve been learning more and it’s seemingly impossible to develop a public API using opaque structs with function pointers. library_module_function naming for the win, lol.

[covert jungle]

Figured it out atlast!!(few hours on this one..) was not thinking like you said. It was only printing 1 combination and i had to specify how many times i want each specific pattern / combination.
Next task was a peace of cake after this one hehe

[final juniper]

you don't need to strictly specify how many times tho

[covert jungle]

How come, not even when you combine numbers and words?

[brazen eagle]

I think they're referring to * and +

More efficient to specify counts though, as those can be unrolled

[covert jungle]

I understand, that makes sence. Was in the world when that was not allowed, hehe

[final juniper]

yeah I was referring to +, it's my usual choice unless it can bring problems, like if you shouldn't select words with more than 3 letters

[brazen eagle]

• and + are greedy operators, which can cause unexpected complications if you're too general with them

Yes I know there are non-greedy versions

The regex state machine is bonkers

[magic falcon]

look-back operators ought to be used way more often

[brazen eagle]

those are....really finicky

[lilac holly]

im putting

#nameInput {
text-align: center;
}

and its not centering it

I made sure its the correct id

[onyx merlin]

is it a block element?

[lilac holly]

what do you mean?

[onyx merlin]

It's a crucial part of css

[lilac holly]

its in a form

[onyx merlin]

I didn't ask what it's in

[lilac holly]

with the submit button right under it

I dont understand what you mean by block elemnt

element*

[onyx merlin]

https://developer.mozilla.org/en-US/docs/Web/HTML/Block-level_elements

https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flow_Layout

[lilac holly]

It says <form> is a block level element

[onyx merlin]

But you said it's inside a form

Not that it is a form.

[lilac holly]

The only html that I have is

the form with the button and text input in it

nothing else

[onyx merlin]

Send code.

[lilac holly]

ok

[lilac holly]

Can I dm you

?

[onyx merlin]

Why can't it go here?

[lilac holly]

It wont allowed me to put more characters

[onyx merlin]

Jeez, send the files...

[lilac holly]

ok

[onyx merlin]

In chat to clarify.

[lilac holly]

Alright

[lilac holly]

here

[onyx merlin]

Problem 1

[lilac holly]

is it the <title></title>?

[onyx merlin]

Ditch the commas.

[onyx merlin]

No, it's the red squiggly line that always shows problems

It's centered.

[lilac holly]

Fixed all of that

but still same problem

[onyx merlin]

What problem? It's centered.

[onyx merlin]

Works in chrome

[lilac holly]

I want it to be centered on the page

[onyx merlin]

Then you don't use text-align.

[lilac holly]

What should I use?

Sorry

Im not really good at html

[onyx merlin]

I'd recommend putting some time into learning. I liked the SoloLearn CSS/HTML5 courses.

Personally I'd use css flex

[lilac holly]

I tried this

#nameInput {
text-align: center;
display: flex;
justify-content: center;
align-items: center;
}

Doesn't seem to work

What did you do to center it?

[onyx merlin]

I learnt CSS flex

There's no real way of avoiding it, you're going to have to sink some proper time into learning the language

[lilac holly]

CSS Flexbox?

right?

[onyx merlin]

No.

[lilac holly]

Then what is CSS Flex?

[true pumice]

https://tenor.com/view/local-dumbass-learns-how-to-use-google-gif-21412951

[onyx merlin]

Honestly, you're avoiding the time sink of learning again. @lilac holly

If you learn for yourself and develop self-reliance, you will go far in this field

[lilac holly]

I have looked at a lot of things to see on how to fix it

but none worked for me

That's why I come here to ask for help

[onyx merlin]

I can tell why from this

[lilac holly]

#nameInput {
text-align: center;
display: flex;
align-items: center;
}

I tried this too

[onyx merlin]

Same problem

[lilac holly]

oh

[onyx merlin]

You really need to learn how it works, otherwise it's going to cause you to run into the same problem over and over.

[lilac holly]

I know how it works

w3schools

is telling me that it aligns the flex item in the middle

but it doesnt

[onyx merlin]

No, it doesn't. Because you are misusing flex.

Hence the need to learn it

[lilac holly]

Can you tell me what you did?

Ill still go read about it

[onyx merlin]

https://css-tricks.com/snippets/css/a-guide-to-flexbox/ You need to understand what a flex item is.

[lilac holly]

You said it wasnt CSS Flexbox

[onyx merlin]

Whatever.

It's clear to me that every time you come here to ask for help, it's because you have not got the fundamentals down and you're running before you can walk so to speak.
When someone lets you know that, it's the same hostility. I'm not going to help you anymore.

[lilac holly]

Crazy, how every time I ask for help about something in programming I get backfired or told to go to google when I already have looked there. I know my fundamentals in HTML and can understand it pretty well. You can't find one HTML Fundamentals Course with CSS FlexBox introduced as it is a little more advanced. Don't worry about me asking in this channel anymore. I will join another DIscord Server specifically for programming.

[true pumice]

Thank you, please refrain from asking in here^

Gave +1 Rep to @harsh crystal

[lilac holly]

Alright 😐

Flex and flexbox are the same thing, which you'd know if you read the article that James posted. It's a very well written guide, I use it as my go-to reference

[lilac holly]

Didn't need fex

flex*

Already fixed it

Used margins

[brazen eagle]

Yeah except the absolute inside a relative div wreaks havoc on modern browsers and is an accessibility nightmare

[lilac holly]

I am working on a input box

[brazen eagle]

Margins are very, very unreliable

[lilac holly]

not a div

[brazen eagle]

Same difference

Element then

[lilac holly]

I like margin atm as im not working on a html project

Im making a flask project and my goal is not to make it super neat

But thanks for the help

[brazen eagle]

Gods I hope I never find you on my team....

If you're not doing an html project then you sure don't need css

[lilac holly]

So many arrogant people in this channel 😂

[brazen eagle]

There's a difference between arrogance and experience

If you act this way in a professional environment, I'm sorry to say you won't last very long

[lilac holly]

Yeah but you belittle my experience

and call me in a way

trash at programming

[brazen eagle]

Because your solution doesn't hold water

[lilac holly]

My solution worked for me

Flexbox didnt work form e

me*

You are right about flexbox working for divs

[brazen eagle]

You want to centre an element, but did so in a way that'll break as soon as the window changes size

[lilac holly]

Just tested it

Nothing broke

[brazen eagle]

Flexbox should work on an inner element, but it needs a containing element, which you'd know if you read the article

Instead you choose to ignore our advice anyways

[lilac holly]

I used your advice

I went to the flexbox site

read about it

tried some things

didnt work

I asked NinjaJC if he can help me

tells me I dont know the fundamentals

when all I want is just some help on how to do it

the rest ill do myself

[brazen eagle]

Outer div as display:flex, inner element with flex: settings

[lilac holly]

but of course you all are to arrogant to tell me because I lack "experience"

[brazen eagle]

RTFM for the details, but the site is pretty bloody clear

Were telling you to read, and actually read, not skim through in 5 seconds

[lilac holly]

Im confused with this

Do I make the form first a flex container?

Then make the name input for example a item?

flex iem

item?

[brazen eagle]

Left side defines the container, right side the containee

[brazen eagle]

That should work

[lilac holly]

Whats a containee?

Whats inside right?

[brazen eagle]

Thing that goes inside the container, not really a real word I don't think

[lilac holly]

Yeah

I searched it on google

[brazen eagle]

It's late here and I'm tired

[lilac holly]

[brazen eagle]

Regardless of who it's meant for

[lilac holly]

Arrogant to be specific

[brazen eagle]

Doesn't matter at this point. We want you to learn to be self-sufficient. If you have questions about specific content in the docs, that's fine, shows you're paying attention

[tame willow]

I'll assume you're working with a div element when making a flex container. Anyway, "tagging" that div element with the defined class of container will apply its properties in the typical CSS fashion (read: exceptions apply that you need to learn). When you define display: "flex" you tell that container to use the flex system of element positioning for anything inside that div element. You can have the items ordered left to right, right to left, top to bottom, or bottom to top. And, you can have them spaced in different orientations. row is left to right, column is top to bottom. There are, reverse options too. This means that the first item to display will depnd on the orientation of your flex container. assuming it's a row (default) then the first thing to show up will be the first element you include inside that flex container; but you can specify the order direciton as is noted on the right hand side of that image.

<div class="container">
<div> item 1</div>
<div> item 2</div>
</div>

.container {
 display: "flex"
}

Should resolve into a couple of side-by-side phrases where item 1 is the first item (on the left). I'd highly recommend having a code editor like VSCode on yoru PC and installing an extention like LIve Server to allow you to play with learning these basic elements of web design.

NOTE: you'd have to either include the CSS as an import or define the CSS a <style> tag before the div element for it to render properly. It's all interpreted and rendered in order.

[clear lodge]

I'd just change 'container' to a class 'flex', as that indicates exactly what it does. 'container' doesn't really tell you anything

[magic falcon]

This is exactly the reason I don't engage with some people. Once they discount my advice twice, they don't get help any more.

[lyric mirage]

I think I've been guilty of that, to you.

I seem to remember at one point I don't think I was very nice...

I tried to find it, but it was on my other account.

[remote wren]

hello!!

you may see this post/question somewhere else but im just trying to gain info.

im doing a OSINT project too look for and analyze OSINT-frameworks and find pros and cons etc.

my question is what osint frameworks do you use and why and etc.

you can just messge me private in DM. no need to say hello etc just type what osint-framework you use and why etc.

[carmine hull]

sadly, we don't seem to have an osint channel on here

[brazen eagle]

Doesn't sound like a programming question, try #infosec-general

[lilac holly]

<html>
<body>

<h2>What Can JavaScript Do?</h2>

<p>JavaScript can change HTML attribute values.</p>

<p>In this case JavaScript changes the value of the src (source) attribute of an image.</p>

<button onclick="document.getElementById('myImage').src='pic_bulbon.gif'">Turn on the light</button>

<img id="myImage" src="pic_bulboff.gif" style="width:100px">

<button onclick="document.getElementById('myImage').src='pic_bulboff.gif'">Turn off the light</button>

</body>
</html> ```

So the JavaScript doesn't need to be within a <script> element if it's onclick?

[vocal oar]

Thats right

[lilac holly]

What would I call that?

is that because js has different elements dedicated to it?

kinda like how CSS uses onclick also?

[vocal oar]

ye, JS can be used outside of a <script> tag, like done in the code above where the JS is in the button element

[clear lodge]

You should try to use external scripts tho rather than inline js

And then import that js file

But this will also work 🙂

The same also goes for inline css. If you wanna make it super nice and proper, create an external css file 😁

[magic falcon]

[brazen eagle]

[peak cosmos]

mope

nope

[peak cosmos]

yup

[brazen eagle]

still don't know what you want

I cannot read minds, (un)fortunately

[terse token]

Someone understand me While / do while
🛑🛑

[surreal bronze]

while True:
understood

could you be more specific?

[wraith hearth]

while Checks Condition First And Then Runs
do while Runs And Then Checks (||Tricky MF...||)

That's As Far As I Know, Anyway Forget do while D:

[tulip sail]

Use While when you want a loop to run conditionally, use do...while when you want it to run once unconditionally before starting to check

For example, if you need a validated user input:

#include <string>
#include <iostream>

using std::cout;
using std::cin;

int main () {
  std::string name = "";
  do {
    cout << "Please enter your name: ";
    cin >> name;
  } while (name != "Muiri");
}

It makes sense to get the input first before checking, then (and only then) loop

[surreal bronze]

For python, there isn't one built in so you can do something like

while True:
  print('xyz')

  if condition:
      break

[tulip sail]

Realistically do while is just syntactic sugar anyway iirc

[surreal bronze]

or..

var = None

while var is None:
  print('xyz')
  var = something

you get the idea

[tulip sail]

That said, that's still an example of a While loop, not a do while

[magic falcon]

difference between do while and while is primarily an optimization thing - once the code is optimized there is no control over how it executtes

[tulip sail]

That was my memory of it

[magic falcon]

Yeah

I remember I had this argument with a couple of beginner programmers a year or so ago

[tulip sail]

Seem to remember a lecturer saying a few years back that modern C/C++ compilers tend to turn them into basically the same thing lmao

[magic falcon]

I know I've said that in this discord, too

really, there isn't a native code difference between most loop constructs, the exception being for (;;)

[tulip sail]

What does that get turned into again?

[magic falcon]

the reason for that is the check to exit is never evaluated, so it is technically 1 instruction faster than while (True)

[tulip sail]

Ooooh, interesting

[stoic badger]

I remember that as well and from a lurker’s perspective, it was very funny

[magic falcon]

It was super, super irritating from my perspective. They kept saying more and more wrong shit, without giving me a proper chance to explain why they were wrong

[wraith hearth]

i = 10
while i:
  # Do Stuff
  i -= 1

I Like This Kind Of Loop. By Like I Mean It Can Automatically End Itself And That's Kinda Cool D: (Not Cooler Then For Loop Tho)

[surreal bronze]

isn't a for loop at the base level a while loop?

[lilac holly]

If this is C, while is faster than for according to some of my sources that I dont trust completely

[tulip sail]

They're compiled to be basically the same thing 🤷‍♂️

[magic falcon]

It's plausible. But I would need to see some pretty rigid benchmarks to agree

[tulip sail]

Why on earth would you not just do:

for i in range(10)[::-1]:
  # Do Stuff

There has gotta be an easier way to do that lmao

[wraith hearth]

(Not Cooler Then For Loop Tho)*

Im Just Saying Its Cool

[tulip sail]

If you're iterating over a set list of values then a while loop doesn't really make sense

Well, not at that level

[wraith hearth]

¯_(ツ)_/¯

while ... : ...

[tulip sail]

Goddamnit, I knew there was an easier way to do that with range

for i in range(10, 0, -1):
  # do stuff

[wraith hearth]

range(10, 0, -1)

[tulip sail]

Aye

[magic falcon]

If it's python, the actual fastest way is to use a list comprehension

[tulip sail]

If it's python then why are we even talking about speed

[wraith hearth]

Not Really

[magic falcon]

kek

[tulip sail]

And yeah, assuming that # do stuff creates a new list

[magic falcon]

there's some sketchy methodology in that video.

[stone kayak]

the ending is the main point, the fastest way to loop is to not loop at all

[magic falcon]

yeah, i can totally agree with that. That's not really a python efficiency though

[brazen eagle]

yes, but if you do that in production code I will hit you with nerf darts

[brazen eagle]

I mean the C compiler will generally unroll loops to optimize

but manually unrolling is a bad idea for maintainability

[lilac holly]

can anyone help me? I'm trying to send input (mouse click) to Microsoft Store app in Windows in the background without giving focus to the app and i cannot get it to work, any ideas?

i'm using a ui automation library (which wraps the Windows.Automation client COM) which successfully grabs the specific ui element, but using PostMessage on it doesn't work, only SendInput with focus

[surreal bronze]

Doesn't sound like something you can do.

Remembering, your sending mouse clicks - if you normally click it with the mouse it'll obviously focus it.

Why?

[lilac holly]

Yeah, that's what i'm trying to prevent

i thought about hooking the window procedure (WH_CALLWNDPROC) and changing the style of the popup window that is being created

i wrote a .dll in lazarus and the installer in c#

the hook .dll is a native .dll in free pascal

i tried many things

i feel kind of lost

[surreal bronze]

doesn't seem possible

[lilac holly]

are you sure? there isn't some sort of a "hack" we can pull on it?

i'm pretty sure if we subclass the window procedure and handle the "CREATE WINDOW" message we could do something no?

it can be easily ui automated, but

[surreal bronze]

unless you were to RE the Microsoft app store and work out whats called for each specific event and then somehow inject into it and call it directly which I dont even think is possible then no, not possible afaik.

[lilac holly]

i want to prevent the window from coming to the foreground

there's no need to RE the app, i can monitor the WND PROC

for that specific event

window message

[north wave]

greatings

[lilac holly]

greetings

[surreal bronze]

yes, and as I said before your sending mouse click events

[lilac holly]

oh shit yeah

[surreal bronze]

which, of course, will focus the window

[lilac holly]

that's what's causing it to go on top

yeah..

[timber fable]

Is it better to program a multi purpose pen testing tool in C/C++ or python?

[vapid cloak]

Python will be easier but with slower execution speed and may not give you access to the low level resources you may need for some tools. C will be very difficult, require a lot of code and careful memory management, but will give you more direct access to hardware and execute quickly. C++ is kind of a middle ground. You’ll have access to advanced high level language features but still have low level access to memory and hardware. Execution speed will also be faster than python. It really depends. If you’re just getting started, I recommend python. Once you’re proficient, only use C/C++ if necessary. Those are my insights and recommendations.

[inland hazel]

also the difference between compiled and interpreted languages

compiled like c and c++ means you need to compile the code every time you make a change to run it

while for python or ruby or lua you can run it directly after the change without waiting on the compile

[timber fable]

Thanks, then I have to figure out how much I care about speed versus coding easiness. I'll probably keep going with python so far as C++ is a lot of headache

[wispy kestrel]

Gave +1 Rep to @vapid cloak

[vapid cloak]

Tbh, you won’t really notice a difference in speed unless you’re doing heavy computations. So, I wouldn’t worry about that too much 👍.

[timber fable]

well, if I ever think of adding hashcracking, would that be considered "heavy computations" ?

[inland hazel]

depends on the hashing algo

[timber fable]

the most famous ones, SHA, md5 , NTLM, that kinda stuff

[inland hazel]

sha1 md5 and ntlm sure

sha512 not so much

if shadow recalls correctly

[magic falcon]

hashing is always 'heavy computation'. Part of what measures how strong a hash is estimated time to forge an input for a pre-determined output

[inland hazel]

the change here is that some of the older hashes are a lot less resource intensive compared to newer ones today.... but yeah juun is right

[timber fable]

Is it possible to have the main program in python, but a separate module for hashcracking written in C++ ?

[magic falcon]

unless you are making tools because you think there is a gap in what the current 'best practice' tools do, you are better off just using the standard tools, when you can

[magic falcon]

https://docs.python.org/3/extending/extending.html

[timber fable]

Well honestly I am doing it for fun, to gain experience, and to prove my scripting skills and make projects to get a decent internship. And if I am lucky enough maybe it goes viral

[inland hazel]

well so far it is basicly only jumbo john and hashcat for offline password cracking

[timber fable]

Now I am gonna need to figure out the drawbacks and if this is a best practice

[magic falcon]

It's almost always a "use your best judgement" call. If you do it, it should be explainable and understandable for the decision you made. "Because it's cool" isn't sufficient, "a personal learning project" is.

[timber fable]

yeah that's something pushing me off of adding that feature currently

[timber fable]

fair enough

[magic falcon]

And the sooner you figure out TDD And BDD if you don't know them, is to your benefit.

[inland hazel]

heard of TDD did not recognise BDD in an instant but figured it out inside of 5-10 sec

[timber fable]

I'll google them

[marble crescent]

Does the rule no help with homework also work here? Cuz i can maybe ask some questions soon but it is homework lol

Its isnt an exam and wont get assessed, its only practice for us atm

[lyric mirage]

Sadly, yes.

But i'm not a mod.

[marble crescent]

Fair enough, stack overflow it will be

Haha

[brazen eagle]

TDD is useful, though requires discipline.

BDD is much harder to go at it alone

[brazen eagle]

can't help with homework I'm afraid. Good luck

[inland hazel]

and is not easily applicable to some types of code bases like games

[brazen eagle]

it's always applicable

if you think it isn't, then you have a design issue

[inland hazel]

the key words here were not easily

impossible is a whole other thingy

[brazen eagle]

you can always break down the spec

you'll generally want to focus on behaviour type code in TDD, but necessarily UI code

though in theory you can automate the UI tests as well

hey all, good night. Does anyone know if there's a way to run C code using the windows api (windows.h) with WINE in linux ?

context if anyone cares: my OS teacher in college is going to teach system calls in C in windows, and i use linux, and i my computer is not that powerful to handle a VM just to code in C, and i really don't wanna have to install windows (i only have one drive, and i really want to not have to dual boot if possible)

[magic falcon]

Not even in theory, there are mock libs to do exactly that on practically every language

[brazen eagle]

depends on the techno and the language, but yeah

though I'd expect Unity and Unreal to have something

[magic falcon]

they don't really do unit testing though, from what i remember

i bet there is a C# or unreal-script plugin for unit testing components though

[brazen eagle]

can probably use NUnit or something for C#

at least I think it's N, haven't used C# in forever

[magic falcon]

that's a unit test framework, right? turns out unity has it's own test runner, not sure if it has all the machinery to fully mock UI elements

        pygame.display.update()

[brazen eagle]

maybe I'm missing something, but I'm not seeing how game() is called

[bronze mist]

game is a second display

[brazen eagle]

can you elaborate what you mean by clamped?

[brazen eagle]

that doesn't tell me how it's called, right now it looks like a generic function

[tame willow]

System calls in Windows :/ Time to protest.

With that, my suggestion would be to just make a VirtualBox install of an older version of windows. Setup an SSH server on your windows install. Expose all relevant ports. Then when you start the instance you can run it “headless” and use VSCodes remote connection feature to connect to the headless VM via SSH. This will reduce the workload on your host machine and still give you access to windows from Linux.

Alternatively, get cloud time on a windows VM from AWS, Google, etc. you can remote connect the same way via VSCode.

    image: docker.io/library/redis:7
    restart: unless-stopped
    volumes:
      - redisdata:/data

Is redisdata supposed to be mapped to my machine as /redisdata? I can't find it 🤔

[stoic badger]

I believe it's trying to mount to a volume named redisdata instead of mounting to a specific folder

  broker:
    image: docker.io/library/redis:7
    restart: unless-stopped
    volumes:
      - /redisdata:/data

I think this would work, but it's been a minute since I've used docker compose and volumes

[brazen eagle]

yeah it's a volume, so managed by docker itself

[timber fable]

Hello,I want to manually manage argparse exception handling, so that my script doesn't exist when encountering an error and simply recalls the parent function and repeats everything from the start. But I can't find the exception/error for when the user types something totally invalid as an argument ( like instead of "-t xyz" they do "sthrandom" with no -t). That produces an error different from ArgumentError or ArgumentTypeError, so I can't except it, I tried the global except: , but that wasn't enough as I need some way to refresh argparser and remove any leftover random stuff in the arguments. I hope I explained the problem clearly.

[stone kayak]

Find the code that validates what arguments there are and check to see what errors it throws?

I personally would advise against this as it's a bit messy and just throw out the --help menu, but if you want to do it I'd suggest reading the argparse source 😄

[stone kayak]

If I do this would it wipe out my redis data 🤔

there is significant metadata in redis i cannot lose and i am trying to back up 😄

ah i believe docker volume ls docker volume inspect gets me the path

[brazen eagle]

Yeah but volumes are handled by docker itself

The layout is not really standard

[tulip sail]

It wouldn't wipe it (the volume would still exist), but it also wouldn't be accessible to the container until changed back

You would effectively end up with two "drives" containing redis data, one at /, the other at the path where docker stores volumes (can't remember -- /var/lib/docker/volumes, maybe?)

[brazen eagle]

something like that

[tulip sail]

Either way you ain't going to be grabbing the data that way

[brazen eagle]

docker-managed volumes are pretty opaque

[tulip sail]

Out of curiousity, what's your go-to for data volumes? I've been kinda dithering between docker volumes and hidden ./.data directories in different projects for a while now

Obviously local docker, swarm would be rather different

[brazen eagle]

generally use docker volumes

[tulip sail]

How are you handling redundancy and backups?

[brazen eagle]

I mean for proper persistence you'd probably need to use a PVC or something from your orchestrator

most of my local stuff is disposable

[tulip sail]

Interesting
I really need to go do some Kubernetes

[brazen eagle]

probably bind to an OS path if you need to be able to view it outside the container

or if you're using a DB, I suppose

[tulip sail]

Yeah, that's the conundrum

[brazen eagle]

I use RO mounts for config files that need to be version controlled

think you can import/export volumes though

at least podman does

[magic falcon]

PVC is specific to k8s, there's an equivalent in docker but i don't remember what it is

[brazen eagle]

docker has volumes, dunno what swarm uses

[magic falcon]

but a regular docker volume mount is ephemeral

[tulip sail]

Also volumes iirc

[brazen eagle]

that's why I'm saying it's mostly disposable

[magic falcon]

@stone kayak You could try creating another container configured to allow you to exfil that volume data, but it's going to be messy in best case

[lilac holly]

I googled the issue, couldnt find satisfactory answer.

I am looking for C code profiler to tell me wheres a bottleneck in my code. To be more precise I am looking for it to be online and simple so much that all I need to do is give it my .C file and it will do the rest

[magic falcon]

You are going to be better off using a profiler compatible with your current toolchain

as loathe as I am to give credit to MS for anything, I think they have a really nice built in profiler for visual studio

boooo...the crypto library I'm using fixed the JVM bug I wanted to exploit 😦

[whole yacht]

how could they

[surreal bronze]

Use the older versions 😎

~~#1 rule - never update libraries ~~

[brazen eagle]

yeah they did something weird and I can't seem to find the value I need to bypass the signature

the standard DER ASN.1 encoding returns as invalid

ugh probably because it wants a raw string

[magic falcon]

as in a non-encapsulated literal?

or a reference to the actual canonical String object?

[brazen eagle]

I mean a p1363 encoded signature

it's signing find if I generate it properly, but I'm trying to get it to validate a psychic signature

[magic falcon]

isn't that vuln one of the reasons ECC is discouraged?

[brazen eagle]

yes

(is for a room)

but I think I'll need to find an alternative way to forge this

too bad, it was a cute bug

or I can try using spring boot I guess

[surreal bronze]

Huh weird

Do you not have older copies or does it auto update?

[brazen eagle]

I set an older version of the dependency, and am normally on a vulnerable JVM

the POC'd value seems to not work

[magic falcon]

https://neilmadden.blog/2022/04/19/psychic-signatures-in-java/

interesting article I found on this problem

[brazen eagle]

that's the one

[brazen eagle]

I should in theory be able to throw a bunch of A's at it but that appears to crash the lib, so now I get to break out the debugger

[magic falcon]

Interesting. Maybe you aren't using the right version of the bad lib?

[brazen eagle]

Checked the code, the version I have doesn't have the check. But it appears to be crashing earlier when it tries to convert to the ASN.1 format

ah damn their implementation is flawed

[brazen eagle]

ok that required some arm-twisting....

so umm, hacky code is hacky

Gods why is intentionally breaking something so difficult?

[magic falcon]

Shift left works?

[brazen eagle]

Yeah but also frameworks are including better defaults

Also I think the library had an inadvertent bug that improved security

It was converting my A's to 0x300402000200 instead of 0x3006020100020100

Can any body tell me resources to learn bash for free

@lilac holly Here please 🙂

[lilac holly]

https://gist.github.com/66672136ca90731dc841d811aa7bd075
This is my code its kinda noob , bc i started python yestesday
I get a problem that is
else :
new_number2 = "not defined"
This line in the code is not working

[swift condor]

Can you share the full code snippet here please?
What is the goal of this variable? What error message are you getting? Did you search for that error message online?

[true pumice]

That's such a big OR chain aa

[lilac holly]

Its not error

Everything is working

[true pumice]

So

You need to set flags throughout your program

Random print statements that show you how your program flows

But you're also misusing if statements

You can't say if var == 'a' or 'b', you have to say if var == 'a' or var == 'b'

@lilac holly

[brazen eagle]

I'm pretty sure there's a library function to tell you if something is numeric or not

[magic falcon]

There is

[true pumice]

int() will raise an error

[magic falcon]

There are multiple libs that have that check, for different purposes

[brazen eagle]

Yeah but something like isNumeric or isAlpha

Not super familiar with python though

[true pumice]

try:
  int(num)
else:
  print("Your variable is not a number")

You can use isinstance() or type() but there's issues with them detecting the wrong data type because Python

[brazen eagle]

I mean if you're just going to throw an error for using letters, then throw a generic error saying you need integers instead of checking each case explicitly

Try else for exception handling in Python?

Also the original code will break past 10

But not knowing the spec, this may or may not be an issue

[true pumice]

WHOOPS I meant try except

am tired

[brazen eagle]

Yeah ok that makes sense

[magic falcon]

if you can't use a lib for some reason, it's always always better to convert the letter to the ordinal value and do a bounds check for your range

[brazen eagle]

Yeah but that'll convert to the ASCII range for the character, yes? Well, UTF-8 more likely

[magic falcon]

there's still an ordinal value; the encoding shouldn't matter, regardless of ASCII, LATIN-1, or UTF-N

IIRC ord() gets the ordinal within the encoding set

[lilac holly]

Why is that

[wraith latch]

Because of the syntax that Python expects. The Or statement lets you combine multiple condition statements, so you need to write it that way because python will only accept it in the form of if var is equal to 'a' or var is equal to 'b'

[true pumice]

Well or 'b' resolves to true

[lilac holly]

Ok

[wraith latch]

As @true pumice just mentioned, otherwise the 'other' statement will return true. Because you want it to check if this, or that, or the other, etc.

https://www.w3schools.com/python/python_conditions.asp

[lilac holly]

Is there a easy way to do it

I had to write all the alphabet

Any easy way

[true pumice]

Yes

You can set the alphabet as a list and then iterate over the list

https://www.geeksforgeeks.org/iterate-over-a-list-in-python/

[lilac holly]

I still have to write the alphabets

[true pumice]

Mhm, but, unless you want to import an outside module, you will have to write in manually

[lilac holly]

Like

[true pumice]

Google "import alphabet Python"

[lilac holly]

Oh and the functions name.

[magic falcon]

Not even the syntax that python expects. It's basic programming truth condition evaluations.

[hybrid cypress]

Hello (im new here so if this is the wrong chat for this question pls let me know and Ill delete my question and go to the recommended chat) , What is the best way to learning programming in your opinions, ive got a bit of IT experience but ive never really gotten into programming and I have realized that Im going to need to get good at that.

checked pinned AHHH well, if anyone has any other recommendations?

[magic falcon]

If you have system admin background, start scripting with bash or powershell. Learn to automate tasks with python, and eventually the things you want to do will require more knowledge and effort; programming is an application of problem solving. If you can write an intelligible flowchart, you are halfway there.

[hybrid cypress]

ok, Thank you!!!

Please re-read the rules of the server 🙂 #rules

[timber fable]

should I use setuptools for a tool made for linux? Or there is a better way to make an installation for my tool on linux?

[inland hazel]

oh boy is that a rabbit hole

[timber fable]

I want it to be fully integrated with the linux system, like when I type in the terminal:
myToolName
it should turn blue and be accessible from anywhere in the system

[surreal bronze]

So compile it into a binary executable

Then add it in your PATH

Or just add a shebang and chmod+x

Then add that to path

But eh that presumes the user has python on their system at that path

Which if it's Linux, most likely is

[hollow sorrel]

a symlink works also, no ?

or create an alias for it

[surreal bronze]

You'd still need to add the symlink to a directory in PATH

Alias sure that works too

[brazen eagle]

You could also in theory package it

But that may be painful

[timber fable]

yeah I used this

thanks

[timber fable]

I finally published the first release

https://github.com/MohamedKarrab/ktool

what do you think?

[brazen eagle]

why does everyone fall into the same trap...

so first of all, please include a readme showing how to use the tool

second, I'm not at all sure how the command line arguments you specified are meant to be input

oh gods I just saw, and wow that's a hack... not the most intuitive way to ask for parameters

I'd prefer to see a collection of standalone utilities rather than a menu

one thing on the ssh bruteforcer, if you throw as many threads as username-password combos then you'll break either the client or the server

[timber fable]

it's straightforward but yeah why not

[timber fable]

I figured it would be easy to implement it that way

[timber fable]

a menu looks cooler

and I'll fix that bruteforce issue ig

thanks

[surreal bronze]

Oh blimey

Okay, firstly - if you really want to go forward with this I'd suggest making a pypi package using https://python-poetry.org/ also, for taking arguments I'd suggest using https://click.palletsprojects.com/en/8.1.x/

Users don't want to have to run the tool, then give input to a menu - it's long, ineffective and not good for incorporating it into scripts. Also, consider not using a banner for accessibility - it rather clogs up the terminal and again, isn't necessary (see https://skerritt.blog/making-hacking-accessible/). In this case, less is more. Also consider cleaning up your readme more (see https://skerritt.blog/make-popular-open-source-projects/ for some tips), I don't think having a massive Todo list on there is entirely helpful

Also, please use a library like https://github.com/Textualize/rich for printing instead of using these ugly escape sequences.

In terms of the file structure, as mentioned earlier I'd suggest using poetry and making it into a package (with main and init) instead of using setuptools which iirc is quite old and rarely used now a days

Again, using something like click or argparse will avoid you having to use an extremely hacky ugly solution like this

poetry init 
poetry build
poetry publish

Also checkout https://pypi.org/project/black/ and https://flake8.pycqa.org/en/latest/

For cleaning up your code

I can see a lot of code that's been repeated (functions too) , flake8 should deal with thoes

[magic falcon]

flake8 is a style and linter, it may not pick up on copy paste code as well as you think

flake also won't remediate those problems, just make you aware of them

[surreal bronze]

Ah, maybe I'm getting mixed up with another tool

[magic falcon]

black will reformat though, but I've had problems running it against code i didn't write

namely, the tab-equivalent spacing sometimes messes up

that said, i still recommend both

[surreal bronze]

I can also see your defining a function within a while loop so that'll do that in every iteration of it .

You've done an extremely hacky solution for getting input from the user, from what I've seen at least a third of all your code is just managing that. By using something like click and not a menu, I reckon you'll be able to make a good chunk of all that redundant and hopefully minimise / clean the whole code up a bit

[surreal bronze]

Huh interesting, haven't had this problem but ty for the insight - will lookout for this when I use it next

[wispy kestrel]

Gave +1 Rep to @magic falcon

[surreal bronze]

cc @stone kayak has a lot of experience with making open source hacking tools (and certainly helped me out a ton with making mine) so maybe they'll be able to give some advice too 🙂

Anyways, wish you the best and gl with the project, if you have any follow up questions fire away

[tulip sail]

Oh, Jesus Christ. Forget the possibility of breaking stuff with the threads, even if it did work, the thread startup costs would be insane, and you won't get any performance benefits anyway given you are limited to the number of logical cores available.

I.e. you waste a tonne of resources on making thousands of threads, almost certainly break something in the process, and can't even run them simultaneously anyway 🤷‍♂️

Thousands of threads between 16 logical cores is still just 16 concurrently. The rest is context switching. How intensive do you think context switching between thousands of threads is gonna be lmao

[magic falcon]

Some lessons have to be learned through experience

[tulip sail]

This is true ask me how I know

[magic falcon]

kek

[timber fable]

I really appreciate your help mate! Thanks for the insights!
I'll look into all these links and suggestions further and see what I can change, and what would be better.
But I got a few things to say about how and why I structured the tool this way:
The reason I thought of a menu, is because I didn't want to make'em separate standalone scripts that run and do their jobs by themselves. Because from my pov, the only reason that would make any people use this tool is that it's all stuffed in one place and easy to understand/grab, if they were separate in any way and you had to use them as if they were them own tool, then why don't you just search for the single best tool for every functionality you would need instead of using this random stuff. I say this because I know I didn't come up with anything new, and that I my current level it's pretty hard to outperform any single tool in it's main functionality, so I'll just stuff everything together and make the tool look like it can do a lot of things. I want people to psychologically rate the tool as whole chunk, instead of rating every functionality on it's own, because I did most them in a pretty trash way and I am working on making them better.

[wispy kestrel]

Gave +1 Rep to @surreal bronze

[surreal bronze]

I understand, but instead of doing an interactive menu that takes time and is inefficient, why not have something like

ktool --file-download xyz
ktool --ssh-brute xyz
ktool --info-gather xyz

It means that you can easily run the command, let it do it's thing and then come back to it when it's finished

Instead of having to wait for the prompt to show up, then manually enter the option you want

Do you see what I mean?

[timber fable]

I don't think the prompt takes much time to show up like metasploit does. Besides, maybe people will get used to it and it becomes faster and more intuitive to use? I'll put the same option for going back (maybe number 77), and If it were the first time for me using the tool it would be easier to follow a menu (max: 3 steps) instead of reading the README.md and searching for how to use the tool.
But yeah the way you mentioned makes sense too and I'll check on more tools using the menu system and see how well they are performing and how easy it is to use them.

[timber fable]

and what can give a plus to this way is the tab complete feature, I should really think about this

[surreal bronze]

ktool --help for a help menu

[surreal bronze]

Yup, if you look at popular open source tools you'll see that they mostly all follow this format

Hydra, fexobuster, gobuster, ciphey, ffuf, nmap, you name it

[magic falcon]

They follow that format because that is the unix development guide's reccomendation.

If you want to develop a tool that is more likely to be picked up by the communities, separate functionality from interactive mode.

[timber fable]

This will force me to look for much more optimal solutions, and maybe remake what whole tools do just because I added (and still wanna add) more options. It can really get out of the scope of this being a simple personal project

[brazen eagle]

Strike the -- on the tool to use

Also having proper library code for the tools may help if one wanted to integrate them with their own ui

Don't forget unit tests if possible, and try to keep your code DRY

[inland hazel]

gets out the garden hose time to make this the wettest code ever

[brazen eagle]

Dry meaning "Don't Repeat Yourself", within reason of course

[magic falcon]

There are very few exceptions, of course. Building factories to implement a UI functionality as a prototype typically involves a stupid amount of duplication of UI element code, as diagnosing specific element problems can be really really difficult if implemented generically. (Looking at you, JavaFX)

[brazen eagle]

and I hope to never have to do this

[magic falcon]

it was part of my undergrad research. I built a control plane for a UGV, it was for an engineer so there was approximately 100 buttons and output displays on the UI

[brazen eagle]

that sounds about right for uni work

[timber fable]

I think this is very similar to how I thought

all in one thing vs does one thing

and does that well

[brazen eagle]

Last part is key

[magic falcon]

Again, go read the Unix Developer Guide.

[timber fable]

I'll check it out

[timber fable]

it's this right ? https://www.netiq.com/documentation/identity-manager-48-drivers/bi_impl_scripting/data/b8n6ps6.html

[magic falcon]

That's a guideline document for a specific company. There is at least 1 actual book that is a really good investment if you plan on making tools.

[timber fable]

[floral bone]

Hello,
Can anybody tell me why the def start() always gives me an error on the code that comes after it?

name = input("Hello, welcome to this simulation. First, I need to know your name. ")
print("Hello", name ,"my name is Jack, and I am your host today.")

mood_success = False
def start():
mood = input("Secondly, tell me your mood. ")
if mood == ["sad", "happy"]:
    mood_success = True
if mood == "sad":
    sad_mood = input("I am sorry you're feeling sad. Is there anything I can do to fix it?")
    if sad_mood == "yes":
        input("Great! What can I do?")
    if sad_mood == "no":
        print("Aww...")
else:
    print("I'm sorry, just tell me your mood and nothing else.")

start()

  File "C:\Users\****\Desktop\python\Test\main.py", line 6
    mood = input("Secondly, tell me your mood. ")

If I move def start(): to anywhere else, say above a if statement, it will say that if statement under the function has an error.

I'm trying to make it restart from the mood = part if the user puts in anything other than just the mood.

[lilac holly]

it works fine if u indent it all

name = input("Hello, welcome to this simulation. First, I need to know your name. ")
print("Hello", name ,"my name is Jack, and I am your host today.")

mood_success = False
def start():
    mood = input("Secondly, tell me your mood. ")
    if mood == ["sad", "happy"]:
        mood_success = True
    if mood == "sad":
        sad_mood = input("I am sorry you're feeling sad. Is there anything I can do to fix it?")
        if sad_mood == "yes":
            input("Great! What can I do?")
        if sad_mood == "no":
            print("Aww...")
    else:
        print("I'm sorry, just tell me your mood and nothing else.")

start()

[lilac holly]

didn't see this woops

name = input("Hello, welcome to this simulation. First, I need to know your name. ")
print("Hello", name ,"my name is Jack, and I am your host today.")
mood = input("Secondly, tell me your mood. ")
    
mood_success = False
def start():
    global mood
    
    if mood == ["sad", "happy"]:
        mood_success = True
    
    if mood == "sad":
        sad_mood = input("I am sorry you're feeling sad. Is there anything I can do to fix it?")
        if sad_mood == "yes":
            input("Great! What can I do?")
        if sad_mood == "no":
            print("Aww...")
    
    elif mood == "happy":
        print("I'm happy you're happy! :)")
        
    else:
        print("I'm sorry, just tell me your mood and nothing else.")
        mood = input()
        start()

start()

i think this is what ur looking for

[floral bone]

What's the global mood?

[lilac holly]

it makes the mood variable accessible to all scopes

without it, you wouldn't be able to set the mood to something else at the end cause it's outside the function's scope

without it you'd get an error like this

[floral bone]

Oh okay, so it makes it available for changes?

[lilac holly]

yee

[floral bone]

If I entered hey im sad at the start, and then later would add "sad" it would come up as "hey im sad sad", or not show up at all?

but with the global variable it would reset the variable and only add the "sad"?

[lilac holly]

nah its for the mood not the name

there's no code interacting with the name variable so nothin weird would happen

do u know about scopes sxdtune?

[floral bone]

I meant the mood

[floral bone]

Nope, Im gonna read up on it tho. First time hearing about it actually

Im really, really new to coding

[lilac holly]

it's all good

really really important thing to know

[lilac holly]

and nah it would just repeat

[floral bone]

This happens:

Hello, welcome to this simulation. First, I need to know your name. Alex
Hello Alex my name is Jack, and I am your host today.
Secondly, tell me your mood. sad
I'm sorry, just tell me your mood and nothing else.

When I send "sad" it gives me the error, but when I send Happy it goes forward

name = input("Hello, welcome to this simulation. First, I need to know your name. ")
print("Hello", name ,"my name is Jack, and I am your host today.")
mood = input("Secondly, tell me your mood. ")
    
def start():
    global mood
    
    if mood == ["sad", "happy"]:
    
        if mood == "sad":
                sad_mood = input("I am sorry you're feeling sad. Is there anything I can do to fix it?")
        if sad_mood == "yes":
            input("Great! What can I do?")
        if sad_mood == "no":
            print("Aww...")
    
        if mood == "happy":
            print("I'm happy you're happy! :)")
        
    else:
        print("I'm sorry, just tell me your mood and nothing else.")
        mood = input()
        start()

start()

Ah

Found it

I had tabbed one time too much at "sad_mood ="

Oh wait no

Im stupid

Same error

Maybe It's because I've added multiple if statements in one?

[lilac holly]

nah

it's cause it's all wrapped inside this one line

if mood == ["sad", "happy"]:

so it's checking if mood is equal to a list, with elements "sad" and "happy"

if u get rid of that and indent the rest of the code properly it should work

name = input("Hello, welcome to this simulation. First, I need to know your name. ")
print("Hello", name ,"my name is Jack, and I am your host today.")
mood = input("Secondly, tell me your mood. ")
    
def start():
    global mood
    
    if mood == "sad":
        sad_mood = input("I am sorry you're feeling sad. Is there anything I can do to fix it?")
        
        if sad_mood == "yes":
            input("Great! What can I do?")
        if sad_mood == "no":
            print("Aww...")

with this code it doesnt work on happy for me

but if you get rid of a tab so that it's outside of that if mood = list then yea it'd work
