Rewriting the Ruby parser
At Shopify, we have spent the last year writing a new Ruby parser, which we’ve called YARP (Yet Another Ruby Parser). As of the date of this post, YARP can parse a semantically equivalent syntax tree to Ruby 3.3 on every Ruby file in Shopify’s main codebase, GitHub’s main codebase, CRuby, and the 100 most popular gems downloaded from rubygems.org. We recently got approval to merge this work into C
Gamedev in Lisp. Part 1: ECS and Metalinguistic Abstraction - cl-fast-ecs by Andrew
Gamedev in Lisp. Part 1: ECS and Metalinguistic Abstraction In this series of tutorials, we will delve into creating simple 2D games in Common Lisp. The result of the first part will be a development environment setup and a basic simulation displaying a 2D scene with a large number of physical objects. It is assumed that the reader is familiar with some high-level programming language, has a gener
If you combine this with the Unicode table, you’ll see that English is encoded with 1 byte, Cyrillic, Latin European languages, Hebrew and Arabic need 2, and Chinese, Japanese, Korean, other Asian languages, and Emoji need 3 or 4. A few important points here: First, UTF-8 is byte-compatible with ASCII. The code points 0..127, the former ASCII, are encoded with one byte, and it’s the same exact byt

Parsing Protobuf at 2+GB/s: How I Learned To Love Tail Calls in C
[Note: there have been several developments in this space since this article was published. See A Tail Calling Interpreter For Python (And Other Updates) for the latest information about this technique.] I just landed an exciting feature in the main branch of the Clang compiler. Using the [[clang::musttail]] or __attribute__((musttail)) statement attributes, you can now get guaranteed tail calls i
Tier 4 Support § Support for these targets is entirely experimental. If this target is provided by LLVM, LLVM may have the target as an experimental target, which means that you need to use Zig-provided binaries for the target to be available, or build LLVM from source with special configure flags. zig targets will display the target if it is available.

It is December. That means annoying Christmas things are everywhere, including but not limited to the annual programming semi-competition known as Advent of Code. The problem with Advent of Code is that it is a waste of time. Most of the puzzles are in the realm of either string processing (somewhat applicable to programming), logic puzzles (not really applicable to most programming), or stupid go
25th May 2025 Anthropic publish most of the system prompts for their chat models as part of their release notes. They recently shared the new prompts for both Claude Opus 4 and Claude Sonnet 4.

Here are my highlights, including a dive into the leaked tool prompts that Anthropic did

Reading the excellent article by JeanHeyd Meneide on how broken string encoding in C/C++ is made me realise that Unicode is a topic that is often overlooked by a large number of developers. In my experience, there’s a lot of confusion and wrong expectations on what Unicode is, and what best practices to follow when dealing with strings that may contain characters outside of the ASCII range. This a

Metashapeで全天球画像をキューブマップに変換
Metashapeは全天球画像(エクイレクタングラー)の処理に対応していますが、アライメント結果を他のSfM系ソフトで利用する場合は、全天球画像のままでは渡すことが出来ません。 postshot、RealityCapture、Inria 3D Gaussian Splatting等は全天球画像には対応していないためです。 しかし先日smert999氏が「Agisoft_metashape_convert_to_cubemap」を公開されました！ Metashapeでアライメントした全天球画像を、そのアライメント結果を維持したままキューブマップに変換できるというものです。 Theta, Insta360等で360度動画/全天球画像撮影 → Metashapeでアライメント → キューブマップ変換 → RealityCaptureで活用・postshotで3DGS生成 といったワークフローが可
HTML Whitespace is Broken September 2, 2024Recently, I was working on a project which required a deeper understanding of how whitespace works in HTML. I was never a fan of HTML's whitespace behavior before as I've been burned by it a few times. But as I dug into it more deeply, I found myself discovering complex design issues that I wanted to explore in a blog post. This is partially to write down
