til

today i learned. tiny notes on things i didn't know yesterday.

loose, mostly one paragraph each. no particular order.

entries

• python: dict preserves insertion order since 3.7
• git: git reflog saves you from almost anything
• unix: xargs -P does parallel in-place
• unix: xargs -P and signal propagation to workers
• zig: @typeInfo and friends - runtime-typed values without runtime overhead
• postgres: SET LOCAL doesn't take bind params; use set_config()
• rust: rustls's prefer-post-quantum feature is a no-op against the ring provider
• bun: bun install only runs a subset of npm lifecycle scripts

closed proposals

• #9 - numeric prefix on filenames. nope, slug + git log are enough.

removed entries

drafts that were referenced in past readme revisions but never landed as files: git/autosquash, git/worktree, jq/null-input, bash/proc-sub, unix/kill-zero, bash/set-euo, lua/metamethods. some are notes i still want to write, some are duplicates of existing entries.
