Goose, James Goose. vi/vim Made some open source software you might already be using. Built the best file search https://t.co/5X6nOmdf5r

While Claude Opus was not being able to get even parity in performance with a gcc my good old human brain seems to be still capable of something. Introducing zlob.h - zig, C, and rust library that is 100% POSIX and glibc compatible and 1.2-2.5x faster than glibc. SIMD, raw syscalls, assembly and hot paths algorithmic optimizations + a WAY better and useful API as an extensions to POSIX interface And some visuals comparing rust's fd using glob crate, glibc find and zlob's purely demonstrative cli

I sometimes need to remind myself how crazy cool is a project I built. It is CRAZY that you can open 500k files repo in your editor and start searching it IMMEDIATELY having results in real type as you type EVEN WITH TYPOS RESISTANCE CONTENT SEARCH AAAAAAAA

My dear software engineers, I am excited to present you my latest achievement in the code search area that I've been trying to tackle for the last months: ACTUALLY WORKING real-time approximate typo-resistant code search. What does it mean? you: can search any code with any typos you agent: for every search of UserController with 0 results will automatically suggest UserAuthController without additional cost It's already live you can try it right now as MCP for file search

Okay Apple, I just implemented a calculator app entirely in arm64 darwin assembly, yes with UI. It might be not as slick and fancy as yours but at least it does not do heap allocation at all so have a constant memory usage no matter what I calculate :D

My dear software developers (and anyone who’s interested in the future of code search): I have crawled through depths of hell to bring you, one of the more important foundational piece of programming: fast, the most accurate, index free, and correct code search Here is a real time code search on leaked claude code sources, linux kernel 100k files, and chromium repo 500k files

Couldn't agree more with Linus here. Making your code running as fast as possible (or just faster than someone's else code) is the best feeling you can get from programming The issue that it is extremely hard to find the project that will pay you for instruction level efficiency

Introducing fff-ai. It's a file search tooling optimized specifically for your AI 1) significantly faster than fzf and ripgrep 2) has fuzzy code search fallbacks 3) better sort and suggestions of access frecency, git status, file size, etc Avg -10% wall time and -17% tokens

I achived the mission. zlob v1.6.0 comes with a walker that is (per platform & feature) 2-5x faster than ignore/walkdir crates while assembling SIMD-first ignore rules set that is over 100x faster to apply than calling libgit2 P.S. if your're ripgrep fan do not watch the video

And I am not joking it is fraeking crazy that fff can do exact file search code search on the whole linux repo (7GB, 100k files) in real time but also it can do TYPO RESISTANT FUZZY CODE SEARCH *mostly* real time (just about 160ms delay per word)

TLDR from their words it is faster than FFF. But it makes absolutely 0 sense to me. FFF searches same query for 250ms. But it doesn't require 550mb index and HOURS of compute to index it Stay tuned I'll drop the article why this is the biggest lie in the file search history

I significantly improved typo resistant matching performance for fff so today I completely migrate my searches to typo resistant grep now I can search *any query* real time on the 40m lines of code repository with typos, missing words, wrong delimiters/casing and so on

In the next version of OpenCode (for sure if my and nexxel pr is goingto be merged) opencode file mentions would be 100x faster than in claude code in addition to that it would - be typo resisant - suggest files/folders opencode recently modified - prioritize the files modified in git

lol no I'm sorry but your file search is s̶h̶i̶t̶ not optimal consider fff you can literally just use it there is a C lib, Rust crate, and even nodejs lib

Announcing odiff v4 - the fastest image comparison tooling revamp! - 20% more stable anti aliasing detection - SIMD first implementation - up to 70% performance boost on some CPUs (avx512) - now compiles to all the platforms (including riscv, freebsd, and mobile) - no floating point arithmetic in best scenario - 40% smaller binaries - 100% backward compatible API

A big announcement! Finally fff.nvim got live grep search that is actually revamping the way grepping works making it a much better search for the code *AND* solves all the QOL problems with the existing ripgrep based pickers

Officially not skill issued in neovim anymore. I built the most memory-efficient file picker UI available in Neovim, and it's the first one to actually use async I/O for file previews. We allocate 3x less memory than the pure lua pickers while mainting custom binary and file index in memory.

Announcing fff.nvim (and standalone fff cli): the file picker you've been waiting all this years. - typo resistant SIMD optimized fuzzy search - standalone native binary for file access that is aware of modification/access times - git status awareness using ABI - good UX
