9. Thoughts on WebAssembly as a stack machine
Thoughts on WebAssembly as a stack machine — eli.thegreenplace.net · 11h ago · ⭐ 25/30 This article addresses the debate surrounding whether WebAssembly (Wasm) is a pure stack machine, specifically responding to claims that it isn’t due to the presence of locals and the absence of
dupandswapoperations. The author argues that Wasm’s design, despite having locals, fundamentally operates as a stack machine where most operations implicitly pop arguments and push results. The presence of locals is explained as an optimization for efficiency and expressiveness, not a departure from the stack-based paradigm. The core argument is that Wasm’s instruction set and execution model remain true to the stack machine concept, even with these additions. 🏷️ WebAssembly, Wasm, stack machine, architecture —10. The Zig project’s rationale for their firm anti-AI contribution policy
The Zig project’s rationale for their firm anti-AI contribution policy — simonwillison.net · 12h ago · ⭐ 24/30 This article discusses the Zig programming language project’s stringent anti-LLM policy, which prohibits the use of LLMs for issues, pull requests, and comments on their bug tracker. The policy emphasizes human-generated contributions, even encouraging non-English posts over LLM-generated translations. The rationale behind this firm stance is rooted in concerns about code quality, intellectual property, and maintaining a human-centric community. The project prioritizes clear, verifiable human input to ensure the integrity and maintainability of its codebase. 🏷️ Zig, LLM policy, open source, contributions —
