CS Illustrated: Welcome!
Our goal is to make computer science topics more accessible to students through visually pleasing and accurate illustrations. The Computer Science Illustrated project began as Ketrina Yim's Master's thesis. Long after Ketrina's graduation, the project lives on as new students with similar passion for technology and art continue to create posters and handouts to facilitate learning for their fellow computer science students. It is with great pleasure and pride that we present the fruit of this efforts to computer science students all around the world through this website. We hope these illustrations bring new understanding and add a little bit of color and enjoyment to your studies!

D3 Graph Theory
A graph (as in "graph theory") is a discrete mathematical structure which deals with objects and pairwise relations between them. Graphs have immense applications in various disciplines of science. Knowledge of this subject is essential for mathematics and computer science enthusiasts.

D3 Graph Theory is project aimed at anyone who wants to learn graph theory. It provides quick and interactive introduction to the subject. The visuals used in the project makes it an effective learning tool.

And yes, it is open-source. Check the code at GitHub. Created by Avinash Pandey, a mathematics and computer science enthusiast.

Whitespace (programming language) - Wikipedia
Whitespace is an esoteric programming language developed by Edwin Brady and Chris Morris at the University of Durham (also developers of the Kaya and Idris programming languages). It was released on 1 April 2003 (April Fool's Day). Its name is a reference to whitespace characters. Unlike most programming languages, which ignore or assign little meaning to most whitespace characters, the Whitespace interpreter ignores any non-whitespace characters. Only spaces, tabs and linefeeds have meaning.[1] An interesting consequence of this property is that a Whitespace program can easily be contained within the whitespace characters of a program written in another language, except possibly in languages which depend on spaces for syntax validity such as Python, making the text a polyglot.

Computer Systems: A Programmer's Perspective, 3/E (CS:APP3e)

Most books on systems—computer architecture, compilers, operating systems, and networking—are written as if the reader were going to design and implement such a system. We call this the “builder's persepective.” We believe that students should first learn about systems in terms of how they affect the behavior and performance of their programs—a “programmer's perspective.”

Teach Yourself Computer Science
If you’re a self-taught engineer or bootcamp grad, you owe it to yourself to learn computer science. Thankfully, you can give yourself a world-class CS education without investing years and a small fortune in a degree program 💸.

There are plenty of resources out there, but some are better than others. You don’t need yet another “200+ Free Online Courses” listicle. You need answers to these questions:

Which subjects should you learn, and why?
What is the best book or video lecture series for each subject?
This guide is our attempt to definitively answer these questions.


Study all nine subjects below, in roughly the presented order, using either the suggested textbook or video lecture series, but ideally both. Aim for 100-200 hours of study of each topic, then revist favorites throughout your career 🚀.

Operating Systems: Three Easy Pieces
Welcome to Operating Systems: Three Easy Pieces (now version 0.90 -- see book news for details), a free online operating systems book! The book is centered around three conceptual pieces that are fundamental to operating systems: virtualization, concurrency, and persistence. In understanding the conceptual, you will also learn the practical, including how an operating system does things like schedule the CPU, manage memory, and store files persistently. Lots of fun stuff!

Biggest image in the smallest space
What’s the biggest pixel size of a PNG image in the smallest number of bytes? I wanted to try to create an image that could be downloaded but whose pixel buffer would be too big to store in the RAM of a PC. Here is a bzip2 file of 420 bytes that uncompresses to a PNG image of 6,132,534 bytes (5.8 MB) and 225,000 × 225,000 pixels (50.625 gigapixels), which, if represented as a pixel buffer of 3 bytes per pixel, takes about 141.4 GB.

CS for All — cs5book 1 documentation
Welcome! This book (and course) takes a unique approach to “Intro CS.” In a nutshell, our objective is to provide an introduction to computer science as an intellectually rich and vibrant field rather than focusing exclusively on computer programming. While programming is certainly an important and pervasive element of our approach, we emphasize concepts and problem-solving over syntax and programming language features.
