Simon Tatham reflects on his experience explaining the 'XOR' (exclusive OR) operator to someone unfamiliar with its practical applications. He notes that while low-level programming in the past necessitated an understanding of XOR, today's high-level programmers often can ignore it. Tatham prepared a lecture on XOR, which surprisingly lasted an hour, and later realized he had more insights to share. He decided to document his thoughts to create a more permanent resource. The summary begins with defining XOR through its truth table but

Type systems are essential for modeling different choices in programming, particularly in the context of library development versus end-user applications. While developers can freely choose their approach for personal projects, library authors must prioritize API stability and forward compatibility. An illustration of this is the Option type in Rust, which is a closed universe that can only be Some or None, allowing for simple and predictable usage. However, this approach restricts future expansion and can lead to API breakage if new values are needed. In scenarios where the

The article discusses the author's experience in developing a torrent application in C, focusing on the download and verification process of torrent files. The application reads pieces of a download from disk, computes the SHA1 hash for each piece, and checks against expected hashes from the corresponding .torrent file. Initially, the downloaded file is empty, but some pieces may have the correct hash if they consist of zeroes. The author prefers a complete verification process at startup to eliminate potential synchronization issues that can arise from not using a
