What's the coolest thing you've ever programmed?

what language did you write it in?

would you like to cooperate on a capitalistic cookie clicker?

This even a compiler for a simple language is cool and fun

it's especially exciting because you have all these choices, syntax and semantics, you can pick any sort of combination

I made a comic page layout generator so I wouldn't have to constantly measure gutter and frame sizes
It works really well for what I use it for.

Don't judge me too harshly haha, but PHP

Do you think you could create this one?

It could make the 3 panel layout easily.
Unfortunately, no recursion.

no, i write my own comics silly

Language?
Always been interested in this.
Dont know if i should learn LUA or stick with python since i already know it

You put in a latitude and longitude, it downloaded topological data from some NASA directory I found by chance, and then rendered it in 3D and you could fly around with a gamepad.

LUA a shit, just focus on getting fucked up good with Python.

wrote it in c.
i'd love to answer any questions you have

I'm a web app guy (pajeet), but I'm fascinated with lower-level stuff. Are you gamehacking here? I'm not familiar with FTL, so I wasn't sure what you were doing in-game at a glance, but it looked like you were using pointers to manipulate or tinker with values at different memory addresses.

Closest thing i know to C is Java.
How does one start to learn how to mess with games? I was thinking on making a bot for a game too, but even though i know code, i have no fucking clue on where to even start to attack such a project

Made a block-based digital logic simulator with a matlab-esque interface. Could load and save circuits, and project files could be converted into blackboxes, so projects could inherit each other and use each other as components. You could also type in unsimplified boolean algebra functions, just like (a^b)+(c*a!), and it would spit out a simplified version in sum-of-products form.

Also made a discord music bot, which sounds really faggy but it was fun to make and very rewarding. I made it interface with last.fm and youtube APIs so you could just give it a song title and artist, and it'd automatically find an appropriate link to play from. Nailed down a solid algorithm for determining the best youtube link to play from. It could also scrobble to last.fm, and it had a radio command that would add music to the queue based on recently played tracks.

I wrote libraries for PIC24 that are used by a club at my university for controlling a drone.

I made a library of premade UI components for SFML, they're designed for use with touchscreens and I modeled it around the look and feel of point-of-sale systems. It has prototypes for dropdown menus, entry boxes with pretty phone number and date formatting, radio buttons, tree view, etc with a mechanism for managing child windows. It was one of my first real programming projects, though, so it's spaghetti as fuck and IIRC the way I did the event handlers is fucking retarded

Hearing shit like this makes me really want to git gud. Most of what you said went over my head, but it sounds badass. What's PIC24 and SFML?

i was just using ftl as an example, but i'm using some linux system calls that i've abstracted away a lot to find values in the program's (FTL) virtual memory and using some other system calls to write to those memory locations.
it's kinda similar to scanmem, if you're familiar with that, but i think it's more sensible to use and it has some really clever optimizations imo.
honestly not too sure how to write bots, but to mess around with memory stuff it's helpful to know c and to read up on the system calls for whatever system you're using. i think it might be difficult to write something that interacts with another program's memory in java although i honestly don't know much about java.

That's awesome. Thanks for the response.

A Peg Solitaire resolver in Go. I programmed things a lot more complicated but I just fell proud of this one.

RuneScape bot that sends my phone a screenshot of its progress every few hours while I'm at work

Sounds neat

I've been feeling really uninspired recently, Jow Forums. I used to have loads of ideas for super ambitious projects but lately I just don't know what to do with myself.

If you want to do games, don't bother with C. C++ is going to offer significantly better options that are innate within the language itself. Games generally lend themselves well to OOP, so C++ is gonna be better pretty much by default. I say this as someone who dislikes C++, and uses C on a daily basis.

I used pygame while teaching myself python. If you're okay with using python, pygame is by far the most intuitive graphics library I've ever used.

A "bot" can simply be a sprite that follows a couple of variables around using PID control. Not actually a bot but for simple stuff, it'll at least look the part.

ty, it's probably not as impressive as you might think it is but I'm happy with what I've made. I'm 100% self-taught so I've had a lot of projects that just never get finished- by the time I've actually figured out the language/API I'm using, the shit I've already written is too fucky to fix in a reasonable amount of time. Thankfully, a few projects (like the ones in that post) actually make it to the finish line.

SFML is an OpenGL graphics library, written in C++. It doesn't really have any premade blocks, like buttons or dropdown menus or anything like that. It's just "draw a box on the screen here" or "when this area on the screen gets clicked, do this." It also has libraries for audio and networking. A similar (and more ubiquitous) library is SDL2.

PIC24 is a 16-bit microcontroller architecture. If you've ever heard of Arduino, the chip on there is similar to a PIC24, but with a different instruction set.

A python program that uses youtube-dl to open a online video in MPC.

That's very informative. I appreciate. I'm self-taught as well, but I haven't delved too deeply into lower-level stuff, although I'm really fascinated by it. I'm trying not to bounce around between too many different things so that I can focus on getting better at what I've learned over the last year and a half. I wouldn't say I hate doing UI, but more and more I realize I love working with backend and actual data, and would also very much enjoy learning C/Assembly and really digging into CS itself.

Jow Forums taught me that C/C++ are languages so hard to grasp that no human being should attempt to learn it, but I managed to compile a program that prints the current time.

A bot that traded ingame items in Realm of the Mad God by buying low and selling high. I would then sell the items on RWT. Made a few thousand dollars.

maybe do more hardware related stuff? program and solder one of these maybe: youtube.com/watch?v=edERx4x5eY0

(cont.) Also, I ended up lending my friend the script and he ended up taking a large portion of my customers, so I updated the script to recognize a certain special trade sequence that would only occur if the person issuing the trade knew about it, and once this sequence occurred, it would search the entire computer for any copies of the script and delete them. It worked a charm, ended up never seeing him use my bot again.

How do you write a bot for a game like that? Which language, and how did you go about it? I'd kill to be able to take advantage of opportunities like that.

how did you manage to interface with the game?

The bot was simple and used AutoHotKey and the ImageSearch function to recognize all the stages of the trade and then move the mouse accordingly. Interestingly, someone released the bot on MPGH although it was bugged, so I cracked it open fixed the bugs and used it for myself. So basically the bot worked solely on screen reading, no actual program data manipulation.

That's really fucking cool. Not familiar with AutoHotKey or ImageSearch or what they're a part of, but that's interesting as hell.

I automated myself out my first IT internship with a python script.

Basically, my job was to toggle a checkbox on a bunch of entries in some old ERP system. 50,000 entries, to be precise.
After the first 50 or so, I realized that the task consisted of the exact same keystrokes, followed by a delay for the old-ass system to process it. 5 minutes later, I had the keycodes for Tab, Shift-Tab, Space and Enter. 30 minutes after that, I had a basic python script that entered an ID number, navigated to the field in question, and toggled it.
I was so proud, I just had to show it off. I had no idea I was about to doom myself. The next day, I come in, and security escorts me to the Head of IT. He hand me a printout of my code, and asks what it is and why I shouldn't be fired on the spot.
>It's a keyboard macro. It toggles the checkbox for every entry in a list. Just follow the comments, you'll see how it works.
After what felt like an eternity narrating the code flow in perfectly clear terms, he was satisfied and let me return to my desk.

My internship ended the week after, with my script only halfway through the list. I realized I had made myself redundant when they told me my script was company property, and I had to surrender any removable media on me for scanning.

And that's how I automated myself out of a job with 50 lines of python.

C/C++ are easy to learn, but extraordinarily difficult to master. They're hard to master for very different reasons: C is extremely stripped down and you have to learn how to work with what it has without being inefficient, and C++ just has an absolute fuckload of different features and quirks.

I've never done anything in full asm, though parts of the PIC libraries are written in asm for the same of optimization/tight timings.

I hate doing UI, but I like graphics in general. Using JavaFX for the digital logic simulator was cancerous and unenjoyable, but the really primitive OpenGL libraries like SFML, SDL, Pygame, etc can be really fun to work with because they're so damn simple.

ooooh, that looks neat. I have tremors and it makes soldering really hard, but I've gotten good enough that I can tack wires onto 0402 resistors to test boards at work, but this will be a hell of a challenge.

That's really fucked up that they did that. I 100% would have done the same thing, eager to show it off and everything.

That's fucked, man. Honestly, if they only needed you for box-clicking, it probably wasn't worth your time anyway. Be proud that you're more skilled and more competent than those morons.

Last I heard, they went under and sold their assets, so it was a sinking ship anyway.

At least I got an interesting addition on my resume out of it. It made landing my next job much easier.

>Pic related. If you learn anything on the job, keep it to yourself.

That looks very cool! Just curious, how are you doing that? Are you just dumping the memory of the PID FTL is running as and then getting a point to the location of the value you want to manipulate? Also, if you have a repo for this project I'd love to see it.

App that takes a picture of coins and calculates the total value. Only for android and only works for Canadian currency

i abstracted what's actually going on quite a bit to allow for optimizations, but it all essentially boils down to the linux system calls process_vm_readv and process_vm_writev
it's all on my github at github.com/asherlie/varedit

hey Jow Forums I really want to write something but I'm gone out of ideas. Don't want it too be too big (e.g. a game engine), already have experience with major languages. What's some cool stuff you're working on/did before?

>Last I heard, they went under and sold their assets, so it was a sinking ship anyway.
Good to hear, and unsurprising. Why would you fire the guy who not only does his job, but has made the work 100x easier and more efficient? I've heard horror stories of employees at big corps doing this and it's probably because low-level managers feel threatened.

I made a screamer file where the user will get a screamer every 1st of the month at 9pm-3am (whenever the user has his computer turned on during that time). I sent it to my classmates and while I was reported for it, it was fun and definitely worth it.

I have a working poker bot, which actually makes money for years.
It's not much but still. The bigger problem is actually, that I get banned too often, the AI itself is pretty good.

already done this as a school project unfortunately but thanks for the idea!

I did the same thing at my job, except I got promoted and went on to develop a toolbox of scripts to automate my department's grunt work and a few apps for tracking the status of day-to-day operations.

Very cool! I just starred it on Github. I have been meaning to get back into C. I studied C in college as part of my Electrical Engineering curriculum. But that was mostly geared towards a combination of embedded systems and control systems; it didn't include much general purpose programming. Once I got out into the work place, I ended up using mostly Python and JavaScript. I've been looking for an excuse to get back into C. The closest I can get to using C in my day to day work activities is potentially using Golang if the chance arises.

that sounds really cool, how precose is the data you got?

An applet to download all the media in a chan thread so I could easily archive memes and hentai.

Actually pretty cool. I would save up coins more often if I had a USD version

If there were an app, that can accurately count money, I would actually even pay a bit for that, but it would have to be almost as good as those machines.

Also it should be able to count bills too, maybe an idea for someone honing his programming skills?

You know, I think I want to do this shit again.
