Knowing how to script should be more than enough for what is being asked on your description. TryHackMe has a couple of room focused on learning how to script and applying it.

azure peak
#

Well that would make sense, I will check out these rooms to see if I am interested in it. For scripting, does that require months of Python training or anything like that?

lilac holly
#

well...I wouldn't put it that way

#

Think of it as a spectrum

#

You can make scripts that do the job but due to the lack of knowledge of the inner workings of Python and some optimization tricks they might be...150 lines long. Right? Then after a couple of weeks learning new stuff, learning from others and working and practicing (leetcode (easy challenges) and HackerRank) you can now write something cleaner that accomplishes the same task in 30-40 lines.

azure peak

Okay cool that makes sense, I will check out these rooms and lc and gauge my level

So question lol
I use C# (.net and wpf mainly) to automate 80% of my daily life and server tasks. How pliable would it be to use say python to automate tasks in pentesting? Such as getting the nmaps, gobusters, etc with a single command? Anyone else mess with this kind of idea?
I'm a software developer/devops engineer professionally so the coding side of it I should have no problem switching over to python.

#

Context: For thm, I use kali running on a vm through my proxmox server

tulip sail

Autorecon (from Tib3rius) is the most common one

Nice. I'd rather use what's already made then reinvent the wheel 🤣

ugh shoot me now, I've spent the past 4 hours trying to get to grips with React and it's not working....

#

State issues ?

brazen eagle
#

I haven't a clue, I just want to make a login page for now

#

And then store the token somewhere

Ah, like localstorage

#

Thank god i dont have to work with frontend that much anymore, have nightmares of my react/redux days 😄

brazen eagle
#

Yeah though I'm trying to make my life harder by trying to use kotlinjs

#

And I'll probably use session storage

crude chasm
#

Hehe, well strict typing is all the rage nowadays and i guess you have the possibility to port it to typescript with kotlinjs?

#

If you want to make your life one more step harder 😄

Soon we'll just have to write pseudocode anyway 🙂

Hey all, not sure if this is the right thread per se but I'll start here since I came across this related to work, hehe 😉 I downloaded that Wappalyzer extention and checked it out a bit on projects I built myself. I have a few sites built on Magnolia CMS. Wappalyzer states; 'Instantly reveal the technology stack any website, such as CMS, ecommerce platform or payment processor, as well as company and contact details.'

Magnolia never shows up. I was wondering why that might be, and if anyone knows a bit about that? It looks to me like Wappalyzer scans the DOM / source and gets its info from there. I checked my DOM and sources in dev tools, there is no reference to Magnolia at all. Would love to know if anyone knows a bit more about Wappalyzer and otherwise, this may be a heads up that Magnolia CMS goes undetected heheh.

Hey Juun, grats on your trial mod 😄 It's all custom HTML, CSS, JS, which is why the source is very clean. None of that messy wordpress like DOM, no Magnolia classes etc. It doesn't look like any CMS is used at all from the front. Thanks, that confirmed my suspicions!

Otherwise you're likely pretty good for information disclosure

Do you know any gamified platform for improving python knowledge and practicing more advanced topics than basic things like variables,loops ?

#

I have checked hackerrank, and I have solved questions until I got last star on both problem solving and python. But then I quit because it started being too focused on math

true pumice
#

Depends on what you're looking for

#

Because most platforms where you practice advanced topics are university platforms and they're more take x input and get x output.

haughty horizon
true pumice
#

Check some of them out and see which ones you enjoy

#

There's also these

haughty horizon
#

Like, knowing threading and multiprocessing and practising about these would be very helpful I guess

true pumice
lilac holly
haughty horizon
#

As I said I have already checked hackerrank and codewars. They tend to be math focused in my opinion

lilac holly
#

there are a couple of advanced python books that can help with you that

true pumice
lilac holly
#

start off by reading "automate the boring stuff" by al sweigart. 100% recommended. I own my scripting skills to that guy literally. It helped me understand a lot of stuff.

true pumice
lilac holly
#

W3schools is good website also.

#

that covers more than python.

true pumice
#

I studied Python for school and honestly, once you learn the basics, while it can be boring, I can pretty much make anything I want with a couple of minutes with the docs and some playing around.

#

@brazen eagle btw Isn't codingame for game devs ?

brazen eagle
#

Nah

#

It's gamelike

haughty horizon
#

I have done like 5 rooms and I was like "Okey enjoyable but why"

brazen eagle
#

It's a lot of algorithms practice

haughty horizon
#

Yep but they didn't seem to be hard to me

#

I thankful tho, thanks for recommendation

brazen eagle
#

They aren't really, no

#

But it's good practice

white hazel
#

Codingame gets challenging when you do competitive ai programming

brazen eagle
#

Those are more open ended, so you'll have to test and verify yourself, then self-evaluate in a retro

haughty horizon
#

I see, thanks!

brazen eagle
#

Game of life is always fun for an optimization challenge

haughty horizon
#

Actually I guess it doesn't matter what I do, they will improve my knowledge about python anyways

brazen eagle
#

They'll encourage self research and experimentation

#

The key is practice, and also to try different things each time

haughty horizon
#

What do you mean by different things, like different projects ?

brazen eagle
#

Different ways to do the same project

haughty horizon

anyone here good with C that would be willing to sort of mentor me in something? i taught myself C about 20 years ago in order to code a MUD. I never really learned pointers and memory etc at the time, but i knew enough that I could code my own functions and fix bugs (as long as they didnt involve memory)

#

fast foward to now, i know more about pointers and memory...what i would like to do is go through some MUD code like QuickMUD and find / fix exploitable code

#

as a way to learn the methods and processes involved in finding / fixing exploits etc

#

maybe do a mock writeup that details the bugs found and mitigations etc

plain path
#

<?php
$exec = system('shell.exe', $val);
?>

im not great at php. this is the entire code needed to make the revshell execute.

why does the system function need a second (arbitrary?) $val parameter
why does it need to be assigned to $exec variable? if thats a variable

#

why cant it be just:

<?php
system('shell.exe');
?>

white hazel

have you tried that? I think you're probably right

# daring aspen anyone here good with C that would be willing to sort of mentor me in something?...

I mean you can always put questions in here, but I'm not sure what you have in mind, modern C compilers (gcc, or frameworks like LLVM) have a lot of built in security mechanisms (unless you explicitly disable them during compilation) so even if you find a vulnerability, most likely the program will just crash... What types of vulnerabilities are you thinking you might find in the source code?

#

Maybe im not qualified to speak on this matter tho, my application security experience is limited^^

tired ether
#

Hello can someone good at C help me spot a memory leak please 🙂

magic falcon
#

have you run your program through a memory sanitizer?

tired ether
#

I am using valgrind right now try, but this is my first time using it. I think I know where the problem it is telling me is, but I can't see what the problem is

#

the function in question is

int * searchEveryOccurence(int * found)
{   
    int lastI = textChunkSize - patternLength;  // last index to be checked, any further len of pattern would bypass end of text array

    *found = 0; // count of found matches
    int foundSize = 0; // current size of found array
    
    int* tmp = NULL;
    int* foundArray = NULL;

    for (int i = 0; i <= lastI; i++) {

        int j;

        // For current index i, check for pattern match character by character, if at any point pattern does not match, break. 
        for (j = 0; j < patternLength; j++)
        {
            if (patternData[j] != textChunkProc[j + i])
                break;
        }
        // this check will only pass if starting from index i in text all positions match the pattern
        // patternData[0, ..., patternLength -1]  == textData[i, ..., i+ patternLength - 1]
        if (patternLength == j)
        {
            // need to make array larger
            if (*found == foundSize) {
                //need more space in the array
                printf("rank %d here\n", worldRank);

                foundSize += 20;
                tmp = (int *)realloc(foundArray, foundSize); // get a new larger array
                if (!tmp)
                    MPI_Abort(MPI_COMM_WORLD, EXIT_FAILURE); // if cannot allocate array abort

                foundArray = tmp;
            }
            // update the found array to store the index in the overall text at which this pattern occurs
            printf("found %d\n", *found);
            foundArray[*found] = calculateOverallIndexInText(worldRank, i);
            *found += 1;
        }
    }
    return foundArray;
}

and my valgrind error is

so I think I am writing an extra byte? but I don't see it

magic falcon

So this is for homework? You should be asking your instructor and TAs first.

tired ether
#

no it's a personal project, I am trying to learn MPI

magic falcon
#

Do you turn this project in for a grade?

tired ether

I have a related project to turn in 2 weeks from now, I am doing my own thing to become more familiar with MPI in the meantime. If this type of question is inappropriate I apologize, I will try to figure it out myself

magic falcon

Usually we don't help with course assignments, projects or assignments. It may be against your academic code of conduct to seek help from us without clearing it with your instructor for the course.

Hey, I'm trying to learn about scopes and lifetimes in C++ and I'm a little confused :
I have something equivalent to the following code :

int* createArrayWithTwoIntegers(int number1, int number2) {
    int resultArray[2] = { number1, number2 };
    return resultArray;
}

int main() {
  int* generatedArray = createArrayWithTwoIntegers(2, 3);
  int result[2] = { *generatedArray, *(generatedArray + 1) };
  cout << "First number : " + to_string(result[0]) + ", Second number : " + to_string(result[1]) << endl;
}

As far as I'm concerned, this code shouldn't work since resultArray is cleared from the stack when the function returns.
However, the code is indeed working and printing both fields of result. Why is this happening?

magic falcon
#

tl;dr: when returning a pointer scoped to a code block, ownership of that data is moved to the caller, copying data if needed. IIRC it's not as efficient as returning a pointer object

#

That's C, not C++ @plucky helm

#

The semantics being asked about were specified C++, so I'm assuming C++14 or newer

plucky helm
#

I am sorry, juun
Have been working on some kernels lately, in C😅

Deleted explanation for wrong context

magic falcon
#

Yeah, no worries. C is just a proper subset of C++ anyway 😄

#

This semantic might be more clear if you use the std::array STL instead of returning a raw pointer

hollow tangle
# fleet vortex Hey, I'm trying to learn about scopes and lifetimes in C++ and I'm a little conf...

The issue is because resultArray is a stack allocated variable so that variable will only exist while the function is being executed however when you return, you are returning a pointer to that array since the stack frame will not exist dereferencing that returned pointer will technically point to invalid memory which is undefined behavior I know modern C++ compilers like g++ are able to detect that the reference is dangling and should segfault when the underlying data is accessed the answer to your other question on why you're still able to print both fields of result and those values still appear is because between the time you call the createArrayWithTwoIntegers function and when you print out that value you are not calling another function which will overwrite that memory if you were to call another function that has some local variables before you print out the result variable you will find that the values will find that the result variable will now become other data

#

Other compilers might handle this ub differently for example clang might find that you're trying to deref that memory and will attempt to keep those values

magic falcon
#

Yeah, you're right. That id properly undefined behavior.

#

It's also not very modern C++ to be dealing with raw pointers that way. Preferred style is to use the std::array because it implicitly supports move and move-assignment to avoid the undefined behavior

#

Formally, it is absolutely undefined behavior - relying on the compiler to make the decision is going to cause the 'but it works on my machine' problems that plague compiling code on different environments

hollow tangle
#

Yes you should use std::array but it will return a copy of the underlying array idk if doing std::move on it will move ownership out (it should) or just create a copy implicitly

#

It would probably be best just to heap allocate it and return a pointer to prevent the compiler from making an unnecessary copy

fleet vortex
#

Thanks to the three of you, I really appreciate that you spent some of your time on this blobheart

fleet vortex
# hollow tangle The issue is because `resultArray` is a stack allocated variable so that variabl...

I got one more question regarding this explanation if you don't mind me asking.
When the function createArrayWithTwoIntegers ends its execution, the returned pointer is pointing to an invalid memory address; is this address empty because it got cleaned up when the function ended? Or is it written with resultArray and it "starts being a candidate to be overwritten" ?
According to your explanation, I assume it is the latter, but I read -out there on the Internet- that it was the first of those options (I'm not saying either is right, just asking to know what really is happening).

hollow tangle
# fleet vortex I got one more question regarding this explanation if you don't mind me asking. ...

You've got the right idea in your second statement the data doesn't get "cleaned up" more so the data "starts being a candidate to be overwritten" like you said, it's honestly very difficult to effectively explain memory management without visualizations here's a video which should help clear some things up https://youtu.be/_8-ht2AKyH4

Not sure what exactly you want to know, but what I like to do is accept parameters as command line args. That way you can use it like script.py target_ip=<ip> router_ip=<ip> mac=<mac_adress>. You could use argparse or something like click. I personally really like click as it's easy to use and has lot's of features (including asking the user for values if you don't specify an argument. That way you don't need to manually ask the user for input). Though I'm unsure if click is available for your python version as it seems like you still use python 2.x

First they imported the modules

# 
from scapy.all import *
from subprocess import call
import time
#

Then they defined the variables and got data from the user using the script

# 
op=1 # Op code 1 for ARP requests
victim=raw_input('Enter the target IP to hack: ') #Input IP to attack
victim=victim.replace(" ","") # Use replace to parse

spoof=raw_input('Enter the routers IP *SHOULD BE ON SAME ROUTER*: ') # Enter router IP
spoof=spoof.replace(" ","") # Use replace to parse

mac=raw_input('Enter the target MAC to hack: ') # Get Mac of victim
mac=mac.replace("-",":") # Use replace to parse
mac=mac.replace(" ","") # Use replace to parse
#

Then they used arp

# 
arp=ARP(op=op,psrc=spoof,pdst=victim,hwdst=mac)
# Looks like a predefined function from one of their imports, most likely scapy but idk
#

Finally, they sent the arp request using another predefined function from a module they imported

No idea what 'conio.h' is, but it seems you answered your own question. As for a C equivalent, you're gonna have to research that yourself I think (most likely it does not exist), but if the file is small enough, it shouldnt be too difficult to translate the class to a struct, and make functions that operate on the struct. Of course, you'd probably have to translate the corresponding .cpp as well

Hi

#

Is python appropriate for writing tools(usable at daily basis) ? Or should go for learning shell or c++ or maybe rust ?

magic falcon
#

Yes

haughty horizon
#

Everybody complains about python being slow

#

Do you think this is true ?

magic falcon
#

For 99% of use cases, it doesn't matter

#

Python code is very fast to write, and the execution is tolerable.

#

It's never going to win performance contests, but it'll get the job done. Unless you are processing huge amounts of data (in excess of 100GB) it will not matter

haughty horizon
#

Okay, got it, thanks @magic falcon

wispy kestrelBOT
#

Gave +1 Rep to @magic falcon

white hazel
#

It’s much much much slower at just about everything

haughty horizon
#

yeeeeep

magic falcon
#

In human terms, it doesn't matter. Performance < usability

#

Pick the language that fits what you need to do

#

You'll write 1000 lines of python in the time it takes you to get 50 lines of C++.

#

So it's a basis of where do you want to spend your time

#

Premature optimization is one of the biggest pitfalls of writing a program to do anything.

white hazel
#

Please. That quote is so abused. It was about micro optimizations, not order of magnitude improvements

#

And go is also much faster and about as easy to write as python

magic falcon
#

In my opinion, for most projects execution speed of the environment is irrelevant until the project actually requires performant code.

#

Setting up a go environment is a bit trickier than python, would not recommend unless someone has a mentor willing to hold their hand through the beginner phases

#

Maybe it's easier with repository versions of go; I've only installed it from github

#

In any case, I've voiced my opinion in response to @haughty horizon 's question. Alper, pick a language you think is going to do the best fit for what you have in mind. Every language has advantages and drawbacks; if you are new to programming those are going to be largely irrelevant until you run into the corners that illustrate the good and bad.

haughty horizon
#

So I wanted to double check my path

#

thanks both of you for your answers

thick inlet
#

hey guys i am new to hacking

#

how can i start

brazen eagle
#

Just to add my two cents to the eternal language debate, readability will trump runtime perf almost any time. For tooling, the difference between languages is almost negligible in any case, as performance is very rarely the top priority

#

You'll generally prefer a maintainable tool to one that runs 10% faster

daring aspen
#

@haughty horizon also python is installed on most machines, so any tooling you write in python will most likely run without much issues. vs trying to do same thing in C or GO you don't have compiler on the machine so you have to do it local then figure out a way to upload your file etc...just easier to write a quick script in python and go to town.

haughty horizon
#

Yes but at the same time I am having issues with making executables from python files. In my opinion this doesn't needed but most of the average windows users don't have python installed.

daring aspen
#

@haughty horizon yes but majority of servers are *nix and have python installed by default. If you are planning to stick with windows then I suppose you are correct.

haughty horizon
#

Nope, but my friends use windows sadly

#

and companies

daring aspen
#

lol and you are planning to hack them 😛

#

haughty horizon

Python has an module specifically to compile to windows .exe formats

#

Pyhton btw

#

I have made the same program before but in java

#

haughty horizon
#

these are unnecessary

unknown.png
#

Actually

#

you use elif soooo first parts are unnecessary

#

and that else is wrong

solar hull
haughty horizon
#

try this one

# 
w = int(input())
h = float(input())
BMI = w / h
if BMI <= 18.5:
    print("U W")
elif BMI < 25:
    print("Normal")
elif BMI < 30:
    print("Overweight")
else:
    print("Obesity")```
solar hull
#

That'd still be wrong.

haughty horizon
#

I am just trying to solve logic errors

#

and unnecessary things

solar hull
#

your solution would solve one part - trying to calculate power of an uninitialized value (BMI). That's sure.

haughty horizon
#

power of what

solar hull
#

the BMI **= w / h part equals BMI = BMI ** (w/h)

haughty horizon
#

Look at my code again

#

I didn't include it

solar hull
#

Yes - you didn't have that, that was a problem in the original code.

#

Read again what I wrote above 🙂

haughty horizon
# 
w = int(input())
h = float(input())
BMI = (w / h**2)
if BMI <= 18.5:
    print("U W")
elif BMI < 25:
    print("Normal")
elif BMI < 30:
    print("Overweight")
else:
    print("Obesity")```

Try adding a . before pizza

magic falcon
#

@coral anchor Python imports can be confusing; it's one of the areas where I think the py docs could be improved. What is your project structure? Can you post a screenshot of how your relate to each other on the file system? Do you have an in __init__.py file in the module?

coral anchor
coral anchor
coral anchor
coral anchor
magic falcon
#

That does not show the project structure. Are all of your files in the top level of your project, or do you have a directory that your pizza.py file lives in?

coral anchor
#

Yeah it has a directory

magic falcon
#

Ok, so you do not have an init.py file to tell python this directory is a python module. That's fine, it's not necessary in this case.

coral anchor
#

Ok

#

What next

magic falcon
#

From the sheet file, you are trying to import the num list from the pizza.py file, right? So you need to do a local import, as Jabba said. You are using python, so use the auto-complete tool to help.

at the top of the sheet.py file, add the line from .pizza import num

#

Since you are not defining the directory as a module, the . tells the python system to look in the current working directory

#

PyCharm will likely throw an error telling you 'local import outside of a package' which is expected

#

rather, throw a warning

#

You can also get a list of potential auto-complete hints at any time with CTRL+SPACE

coral anchor
magic falcon
#

Red or yellow squiggles?

coral anchor
#

Red

magic falcon
#

Post error please.

coral anchor
magic falcon
#

that is expected! because you are trying to import something that doesn't have a package

coral anchor
#

So what should I do

magic falcon
#

My recommendation is do some reading on python modules, packages and imports - in the near term, you need to tell python that this directory is a package

#

you tell it that by adding an __init__.py file

If you want to cross reference, sure. But Security should have at best audit access to AM tools, AM is usually done by a group that isn't security. Usually on-site IT or help desk

spiral wren
#

I usually focus a lot on AppSec because, well, that's what I work on. So, managing these type of assets is not IT or helpdesk responsibility. Plus, a 3rd party, is worse if you have the budget and team to build a custom solution.

Can someone explain me pls the jmp (short, relative) instruction? I swear I read the answers in stack overflow and still don't get it cri

#

For x86/32-bit, this is a 2 byte instruction, where the first byte is always EB, for short jump, and the second byte is the number of bytes before or after the current instruction to jump.

#

I don't get how come JMP RIP-0x10 generates an infinite loop (Because supposedly it's always jumping back to itself.) Shouldn't it be just JMP RIP in that case?

RIP represents the NEXT instruction, IIRC

When you install stuff, use python[x] -m pip install, then it'll install it for whatever python[x] is pointing to -> rather, it installs using whatever pip is associated with that version of python

Or assume its python3 like juun said, you can always check with pip --version tho

I am working on my final project. Where we have to make different processes , need to share information between them, also have too implement multi-threading.

plucky helm
#

Ok, but what is the requirement of sharing a queue (a dynamic data structure) across the two processes?
Can't you process that data in a process and only share the results?

#

Shared memory and queue won't be easier to implement correctly
The queue may allocate outside of shared memory section causing memory leaks/errors😄

thick pendant
#

Actually, i have processes of like customer, manager, cook, waiter etc. Where i have to save the orders in sequence so that the cook can take the very next order in queue. But i can't use queues, as the info can not be shared with queues.

plucky helm
#

Do you know about client-server protocol?
There could be one server maintaining all of the data and then you got cook, waiter ... as __client__s
Yeah, you can use IPC to make different process listen for a message and perform its task and then perhaps respond back with some result(s) depending upon your use-case by making use of signals🙂

#

And there comes process synchronisation as well😄

I’m looking at some python code and I noticed that they imported everything from a module. Why not just import the module?

#

Instead of “import socket” they did “from socket import *”

#

Why would they do that 🤨

haughty horizon
#

when you use import socket, you need to use this syntax to access functions of it : socket.name_of_the_function()
but when you use second one you can directly use name of the function to use it

#

Example

from math import *
cos(60)
-0.9524129804151563
-----------------------------------------------(I opened another cmd)
import math
cos(60)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'cos' is not defined

#

(you need to close and reopen a cmd to rebuild this example)

The latter is prone to name collisions.

Is it still recommendable to use pip this way at all then? Or does it not matter anymore these days? <- Guess as long as you know what python the pip is associated with it doesnt matter, maybe if you're running different python3 versions, but you'd probably want to use pyenv/pipenv then anyways

Python, need to have a multiline input that the user can navigate. (Think nano/notepad) All the solutions I’ve seen so far are just “loop over input”, which would work fine if it weren’t for the fact that the user needs to be able to go back to the previous line.
Secondary question of how do I pre-fill the input() line. (Or in this case, the multiline input)

Hello everyone, is there such a thing like tryhackme but to learn software development?

harsh lodge
#

youtube has lots of resources. there are also plenty of good books

#

w3school offers some

#

like php or javascript and python

#

also i solved my other problem as well. apparently session_start doesn't start a session but allows access to the session. which is bullshit. but php is a dumpsterfire anyway

fleet vortex
#

I'm looking more for some kind of "follow a path" thing

#

With a ranking system and stuff

harsh lodge
#

the resources I noted have that 'follow a path' thing, if you watch a playlist for example

#

i don't think ranking system for programming works out all that well. thm is essentially a puzzle solving site. if you want programming puzzles go with zachtronics games. but that's not really teaching you much in terms of real world coding.

#

anyhow. gonna write my chat in php now. maybe.

So you want to count the number of digits which are even in the given number, right?

#

Initialize a variable to keep the count
numberOfEvenDigits = 0

Loop over the number and get its last digit, at the ones place
digitAtOnesPlacs = number % 10

And then remove that last digit from the number
number = parseInt(number / 10)

Continue this loop till number > 0

And yeah, increment the count if this digit is even

What is your failure mode? What index are you using at the start? What is in that location of your array? Do you have handling for the case of the data in the location of that array?

tired sail
#

The index is staying by 2

solar hull
#

Think about a case where the index stays the same. I can see one there.

#

You're incrementing the index at the end of the while block. But there are cases when that's not all that happens.

tired sail
#

The index++ is out side of the switch
Should it not add the 1 in any case?

solar hull
#

It does. But think about cases when index would not increment.

tired sail
#

Case / the index should stay

solar hull
#

Would it be that there's a / at index 2?

tired sail
#

Oh

#

Also it gose to to / than stay there

#

Also it will stock at the first /

what is the different between =+ and += ?

#

did changed it to += than it worked

solar hull
#

😄 That's... something unexpected. += is an operator adding to the variable on the left side. =+ is the same as assigning a positive number to the variable.

#

=+ isn't really an operator, it's just = and +

can anyone tell me how to do a solution search with angr but limiting the length of the output?
I have a crackme file and it wants a password. I run angr with .explore(find=0xblah, avoid=0xbleh) and it dumps me a string of non printable characters that overflows the buffer. Putting that string into the program does indeed give me the desired answer, but smashes the stack, making it useless. I put another avoid address into the stash smashing detection, but it just doesn't... avoid it for whatever reason.

I tried using the solver, but it's a bit over my head. On top of it it seems like it expects you to know how long your target string is going to be. Do I need to run the solver in a loop to test out of the different lengths?

        is_alpha_upper  = st.solver.And(ch >= b"A", ch <= b"Z")
        is_zero         = st.solver.And(ch == b"\x00")        
        constraint      = st.solver.Or(is_num, is_zero, is_alpha_lower, is_alpha_upper)
        st.solver.add(constraint)

@fallen monolith @thorn finch Does it makes sense to call createProcessA without allocating a PROCESS_INFORMATION block?

#

Probably not right?

fallen monolith
#

it's required to have startup info and process information

#

takes in startup info, outputs process information

#

you'll need the process information struct for accessing the process

thorn finch
#

functions in C++ are weird like that, they take both inputs and where to output some stuff

fallen monolith
#

or you'll need to open a handle to the newly created process

thorn finch
#

So createprocess will return a boolean (true/false) but also the process information which is the variable that u will create

#

That's how I think of it anyways

graceful agate
#

okay.

#

What is the point of doing object oriented, if they don't return objects

insteaf of using input use floatput or whatever u name it^^

solar hull
#

First of all: It's a bad practice to use reserved names or built-in functions as parameter names. It'll just make anyone confused. That example is overriding type

#

Second: that would be defining a function to handle the input and errors within the input. That would likely work. But again, think what you're looping over. Think what you're trying to achieve.

#

Think about the exit conditions for your loop. When does the loop terminate?

" is used for char arrays and ' is for char

tropic minnow
#

"%d"

#

Not '%d'

worthy spire
#

ok let me try

#

thanks it worked

#

so, for char we use this '

We use %s for char arrays

Does anyone know how to make variable data accessible outside the function. Sry if this is a dumb question cuz im new to js

unknown.png
sullen venture
inner horizon
#

sry, i meant object

brazen eagle
#

JavaScript is very very wierd though.

sullen venture
#

yeah... 😄

brazen eagle
#

if you want the data to be accessible outside you'll have to assign it to a variable declared outside

#

But JS still plays VERY loosely with scope

#

hoisting is so counter-intuitive

sullen venture
#

i feel like your abusing .then() a little bit too much if you just fetch some data

#

first day back at work and my brain is fried, but if you tell what your goal is, i try to help

inner horizon
#

So i am conducting some fingerprinting. I have 2 other functions that returns other categories of data. In the end, i want to combine all these objects returned from different functions into 1 for my device fingerprints. However, i am stuck at this simple part where i have issues making this object accessible outside.

inner horizon
brazen eagle
sullen venture
inner horizon
#

yeah its unnecessary, i done it only for testing

sullen venture
# 
const network = async () => {
  try {
    const res = await fetch('http://ip-api.com/json?fields=21233405')
    return res.data
  } catch(err) {
    console.error(err)
  }
}

console.log(network())

it's a different syntax, but could you test if that prints out what you want in the console?

inner horizon
#

not what im actually expecting

The then is the old way of doing promises

#

Async/await is preferred

I'm trying to do something with multiple tables with Oracle SQL but a column keeps adding up and I have no idea why. Here's what the numbers of activities are supposed to be

work.PNG
# 
select a.ic_code,count(*) as activities,SUM(a.activitybudget) as sumofactivitybudget from ic_activities a, registered_ic r  HAVING SUM(a.activitybudget) < (SELECT  DISTINCT allocatedbudget from registered_ic where allocatedbudget = 9000) AND count(*) > 0 group by (a.ic_code);
#

But when I try include another table using the above query I get this

nowork.PNG
#

Haven't tried with joins tho maybe i should have done that first

final juniper
#

it's also weird that you are missing an IC_CODE row if that's the case

#

also your second select is redundant, you are selecting the very same amount you set in the where condition @alpine marsh

#

the group by seems fine, are you sure the numbers should be the same as the first table?

#

oh ok I think I figured it out, have you solved it already @alpine marsh ? look better at what you are doing with your r table

alpine marsh
alpine marsh
final juniper
#

how many rows does the registered_ic table have?

alpine marsh
#

Here's the table of registered

#

don't mind the wrong years

#

for the ic_code

final juniper
#

the fact is that you added the registered_ic table in the from clause, but you are not selecting any item out of it, nor is there any use in a where condition, I suspect that's why your count isn't getting the correct amount

alpine marsh
#

Sounds reasonable, i'll give it a go

final juniper
#

just try removing it from the where clause

alpine marsh
#

holy crap that worked lmao

#

output being weird but i think i can fix that

Gave +1 Rep to @final juniper

you're welcome, i'm happy it works now 😉

Hey guys do you know of any places that actually teach python for free? Codecademy says it's free and then charges you and hackerrank doesn't have much tutorials

rocky tide

#

Would the scientific computing with python course be good? Or us that too broad if a subject to learn?

tender pelican
dusk grove
#

yea

#

rn Im trying to find free courses

#

to learn the language

#

then I will focus on certifications

#

This year in dedicating to mainly learning programming

#

In python

#

As hackers use python quote a lot from what I heard

granite agate
#

There are ton of YouTube tutorial as well

#

Or this if you prefer text based

tawny gazelle

I learn a lot by just trying to write an application and then figuring out what code to use

#

Because the code structure seems to be similar to other applications

Hi guys! I am writing a small script for toggling my wallpaper with keybindings and am stuck in a small issue.

I have an array(or whatever its called) with names of wallpaper currently in ~/.wallpaper directory

I have a currently chosen wallpaper symlinked to one of the wallpaper in that directory.

Directory structure is something like this

    - a.jpeg
    - b.jpeg
    - wallpaper -> a.jpeg

arr=(a.jpeg b.jpeg)

I want to iterate through that arr and check if "wallpaper" is equal to currently pointed wallpaper

From ~/.wallpaper, I did:

for i in {1..2};do
    if diff wallpaper ${arr[$i]};then
        echo "wallpaper points to ${arr[$i]}"
        break
    fi
done

But I get something like
diff: $USER/.wallpaper/a.jpeg: No such file or directory
I'm totally blanked out.

hey guys what are .sh scriptd?

#

scrits*

#

scrips*

onyx merlin
#

Especially very simple questions like that.

dusk grove
#

like if I write a file in python do I have to make it.sh

frozen bison
#

what? no

dusk grove
#

beause python applications Ive made run without .sh

onyx merlin
#

Again. Google first.

dusk grove
#

I did

onyx merlin
#

Because to me, it sounds like you need to keep reading.

long ridge
#

.sh is for shell and .py for python, like .c for C code and .cpp for C++ enz.

dusk grove
#

oh ok thx

I want to make a script in cpp. When I enter certain integer I want to get that number with 15% added to it. So when I take the final number and subtract 15% of that number to get the number I have entered. My initial idea was to

#

fees = (initial price /100) x 15; than final price = initial price + fees; But this is not working well, since when I take 15% of the result I don't get initial value

magic falcon
#

Is this homework?

lilac holly
# magic falcon Is this homework?

Nope, just a script I want to make to automate making prices for my family business. 15% is the fees that booking sites are taking.

magic falcon
#

why are you dividing by 100 then multiplying by 15?

lilac holly
magic falcon
#

And you don't script in C++. It's a compiled language, not an interpreted one.

lilac holly
#

Final goal is to make something that will work, no matter how.

lilac holly
magic falcon
#

You should review HS algebra and learn how to balance your equation.

fleet vortex
lilac holly
fleet vortex
#

I'm not sure I understand your question

#

If you add 15% to a value and then remove 15% from the result, the final result that you get will not be the initial value

lilac holly
#

For example I want to earn 10$ on something, I want my script to calculate how much do I need to increase my price to have 10$ when 15% fees are subtracted

found it, thank you for help
