NOTES ON WRITING WASM

This post provides practical patterns for improving the experience of writing Rust-based WebAssembly (Wasm) using `wasm-bindgen`. The main challenge is in effectively managing the distinct memory models of JavaScript and Rust, which can lead to issues like broken handles and re-entrancy.

YOUR LLM DOESN'T WRITE CORRECT CODE. IT WRITES PLAUSIBLE CODE

LLMs often generate code that is plausible and compiles but is fundamentally incorrect or vastly inefficient. A prime example is an LLM-generated Rust rewrite of SQLite, which was found to be over 20,000 times slower for basic primary key lookups due to critical architectural flaws like missing B-tree optimizations and excessive disk synchronization. This sycophancy is a structural problem in their training.

FILESYSTEMS ARE HAVING A MOMENT

AI agents are using traditional filesystems for persistent context and memory, moving beyond the limitations of LLM context windows. This approach allows agents to "remember" project details, user preferences, and skills by storing them in files. Standardized practices like AI Skills are acting as de facto APIs.

THE SURPRISING WHIMSY OF THE TIME ZONE DATABASE

Time zones are complex, leading experts to advise relying on established resources rather than attempting to code solutions from scratch. The IANA Time Zone Database is an open-source repository for global time zone information, with historical information. However, beyond its technical function, the database also contains an amount of whimsy, like a Canadian intellectual's diatribe against daylight saving.
