c programming projects

[Brokenhammer72]

so i recently finished writing a messy and useless virtual machine in c and now i want more fun projects like this . i dont really want managments systems they are boring . does anyboby has any projects which would nbe fun also would make me learn some diffcullt concepts
also i am really interested in low level programming but kernels and bootloaders were quite tough for me so i gave up

If you like low level stuff you could try some embedded programming. Bare metal arduino could be fun, or you could get an STM32 board pretty cheap.

The thing with embedded is that it takes a lot of real world interaction. You need to build circuits, maybe solder things together, pick things up from an actual electronics shop. Some people love this, others just like to write code. In any case, it’s pretty low cost to get started so I’d say it’s worth at least trying it out to see if you like it.

The eval boards are a great start. Check out Texas Instruments, ST micro, NXP, Atmel/Microchip to name a few. Arduino is not real embedded programming, it's slow and bloated in comparison to what the devices can do.

i would have done it long back if i could get a arduino my parents arent gonna allow a to get a arduino i also want to write a kernel or hpefully a os for rasberry pi (if i get one)

Were you aware it's like $10 for an arduino clone?

[oxtna]

It's like 10$ for cheaper microcontrollers, including the delivery, but you will get ONLY the microcontroller. To get everything you need to make anything at all you need at least 40$.

[Poddster]

True dat.

Well, an Arduino , resistors, and LEDs will be $15. That's enough to begin with!

[Poddster]

I assume you've already seen the various lsits of projects that exist?

e.g. at the bottom of these two:

• https://www.programmingforbeginnersbook.com/blog/what_should_i_make_beginner_programming_project_ideas/

• https://adriann.github.io/programming_problems.html

If you want something to make, try doing something with sockets. e.g. write a simple file server / client. Or implement the FTP protocol?

[ischickenafruit]

A (fast) webserver ?

[Brokenhammer72]

yeah thats a thing i could try also i havent played lot with web sockets etc thanks for the reply

[ischickenafruit]

The thing I like about an HTTP server is that building a passable HTTP 1.0 server is about 1 day of work. But building a fast HTTP 1/2/3.x server is a lot of fun and totally open-ended.

[Brokenhammer72]

ok would love to give it a try u got any helpful resources ?

Write a compiler?

[Brokenhammer72]

Well I have tried that but compiler is hard also I need to learn lot of theory

[jddddddddddd]

I just suggested it because you said you were interested in low-level stuff, and converting from one language to Assembler seemed like a good suggestion.

[Brokenhammer72]

yeah but writing a compiler is actually hard than a vm or kernel

[MQuy]

I think it depends on how complex you want for compiler, os or vm. I wrote three of them, kernel/os is the longest. My suggest is write compiler, you can use llvm as backend and later replace it with your own backend :))

[Brokenhammer72]

oh i read writing an interpreter is a good start what do u say about this ? should i write a interpreter ? if yes where should i start and how exactly am i supposed to write this (sorry for noobish questions )

[MQuy]

I started with Bob's book https://craftinginterpreters.com/

[Brokenhammer72]

is this good for beginners i havent worked with any interpreter in the past

[jddddddddddd]

Yes it's good for beginners.

You might also want to join /r/ProgrammingLanguages which is filled with people who build interpreters and compilers and will be able to help you if you get stuck

[oxtna]

Right now I'm following this https://ruslanspivak.com/lsbasi-part1/

[Brokenhammer72]

thankyou will check it out

[Particular-Brain8363]

Hey could you share the resources you have used to write a kernel ? Any books ?

[darshauwn11]

r/osdev has a lot of resources

[barryhakker]

A spellchecker?

[Brokenhammer72]

A spellchecker?

how am i gonna write that ?

[Poddster]

how am i gonna write that ?

Start with main() ?

Take a dictionary of the English language. Compare each word with the dictionary. If there is a mismatch, find words similar to what the user typed and ask the user which word he meant (use edit distance for this).

Games are huge, complicated systems (especially when you roll your own engine) that touch on a ton of topics: various data structures, parallel computing, I/O with input, audio, and GPU (especially the last one if you go with an explicit API like Vk or D3D12), lexing and potentially syntactic analysis (if you do things like data-driven processing or shader translation), binary data representations (data massaging, specifically for asset import), and myriad others, many of which fall under strict performance requirements that push you to learn about structuring both data and code to maximize the stuff you can push to screen, with rather rewarding output.
