In this article, the author aims to provide a basic understanding of how GPUs work, particularly in comparison to CPUs. They highlight that CPUs are designed for sequential execution, with a focus on reducing instruction execution latency. In contrast, GPUs prioritize massive levels of parallelism and high throughput, making them ideal for applications such as […]
After five years of hard work, the author has completed the world’s first FPGA N64. They have meticulously probed every aspect of the real hardware and have now finished the core, with only some upgrades remaining. The author is proud to have designed the CPU, bus, MIPS interface, PIF/SI interface, ROM reader, RAM controller, and […]
A recent study published in Nature Machine Intelligence suggests that artificial intelligence (AI) can help improve the quality and reliability of references in Wikipedia entries. The study developed a neural-network-powered system called SIDE, which analyzes whether references support the claims they are associated with and suggests better alternatives for those that don’t. SIDE is trained […]

The author of this web content discusses their creation of a 2D flappy bird game written purely in Typescript type annotations. They explain that Typescript types are Turing complete and that they have developed a type-level Typescript runtime using Zig. The game’s code is surprisingly simple, as it operates by threading the game state through […]
Postgres, a battle-tested and scalable software, is highly valued by the author despite its slower speed in introducing new features and limitations with adding plugins and migrating to new versions. One notable missing feature is data versioning, which the author has had to add manually multiple times in different ways. After exploring alternatives and considering […]
