The Art of Programming (Second Edition) is a curated collection of programming problems and solutions originally derived from the Microsoft 100 Interview Questions blog series, later refined into a long-running tutorial and ultimately a published book. Created by July, the series began in 2010 and has since evolved into an in-depth exploration of algorithmic thinking, data structures, and coding interview preparation. The repository brings together 42 classic programming problems from the original series, enhanced with detailed explanations, formula derivations, and optimized solutions. In July 2023, work on the second edition was announced, which expands the project with updated content, new problems inspired by recent big-tech interviews, and introductions to modern machine learning techniques such as XGBoost, CNNs, RNNs, and LSTMs. This collection serves both as a historical record of algorithm problem-solving and as a living resource for programmers preparing for interviews.

CodeCampus is a custom Linux distribution based on Ubuntu 24, designed for beginner developers and CSE/IT students. It delivers a fully pre-configured, learning-first environment that allows users to start coding, exploring, and studying immediately—without manual setup or system tweaking. This comes bundled with essential programming languages, compilers, editors, and developer tooling, including C/C++, Java, Python, Rust, Node.js, Git, Docker, VS Code, Neovim, and a rich set of modern CLI utilities.
