The best way to learn to program is to work on projects, so here’s some ideas for projects for beginners, intermediate, and advanced programmers. Remember: it doesn’t matter whether or not you finish these projects. What matters is what you learn along the way. If you have any ideas for things to add to this list you can email me at firstname.lastname@example.org with the subject “programming project ideas”.
- A program that exits with return status 0
- A program that prints “hello, world”
- A Linux kernel driver for a USB button.
- A C standard library that has memory allocation using the buddy algorithm.
- An arduino program that blinks an LED.
- An arduino program which turns on a motor which closes or opens a window based on the temperature.
- A library that parses xml concurrently.
- A Simple web server that serves up one html page.
- A web server that serves up all files in the current directory.
- A concurrent pipeline that reads in MNIST samples and uses image magicke to turn them into files, and maybe apply some optional filters.
- A concurrent system that runs dijkstra’s algorithm.
- A web server that uses youtube-dl to download youtube videos automatically, save them, and play them back to whoever owns the server.
- A program that uses concurrency, and image magicke to automagically fix the gamma settings for a huge number of image files in parallel.
- A reddit scraper.
- A script that helps you pick out parts for a PC.
- A simple package manager using an sqlite library.
- A script that lets you access firefox web history and use readln to issue queries about it.
- A script that acts as a pharmacist.
- A program that takes an integer and tells you if the integer is prime using a parallelized brute force method.
- A password cracker that uses the Control.Parallel.Strategies library.
- A program that takes in an adjacency list as a CSV file and spits out an adjacency matrix.
- A program that runs K-means image segmentation on it’s input using the accelerate library for GPU acceleration.
- A neural network library that uses dependent types, and the accelerate library.
- A program that can lazily generate all possible tweets.
- An rsync wrapper that backs up your files using snapshot backups.
- A program that finds duplicate files in a directory and makes them the same file using hard links so as to save space.
- A script that grabs a random line from a given file.
- A script that renames every file to include the date and time it was modified in the file name.
Lex and Yacc:
- An XML parser.
- A C compiler.
- A programming language that has all the features you wish other programming languages had.
- A parser for the wavefront obj file format.
- A simple web forum using the yaws program.
- A gopher server.
- A bank website.
- A server that can mine crypto.
- A server that can serve up videos.
- A Debian package server.
- An XKCD comic downloader.
- A script that uses AI to draw googly eyes on images.
- A script that uses rotation, scaling, and translation matrices to trilaterate the position of a thing given it’s distances to four given points in 3D space.
- A neural network script.
- A script that can read a text file and summarize it using transformers.
Projects where you’ll have to decide on your own what language to use:
- A program that reads in a wavefront obj file and displays it in a window, and the user can rotate the model around to see it from different angles.
- A twitter client that uses ncurses.
- A quick script or program that can generate the sound of what hydrogen should theoretically sound like when excited.
- A remote controlled differential drive robot (note: this will require some knowledge of electrical engineering).
