👋 Hi! I’m John Hawthorn
I’m a 💎 Ruby committer, on the 🚋 Rails core team, and on the Ruby Architecture team at GitHub. I most like working on performance, hopefully I’ve made your code run faster too 🤗
A few Ruby projects I've made:
- 📏
vernieris a next-generation Ruby profiler - 🏎️
rapidjsonis a fast JSON parser/serializer (based on the C++ RapidJSON library) - 🗑
discardprovides a simple soft-delete pattern for ActiveRecord. - 🏗️
actionview_precompilereager loads view templates at boot (really this should be upstreamed into Rails) - 🐑
sheapis a tool to analyze Ruby heaps - 🍔
pub_grubis a Ruby port of Natalie Weizenbaum’s PubGrub CDCL-based version solving algorithm, as used by bundler - 📧
dkimis a Ruby implementation of email DKIM signiatures
Some of my non-ruby open source projects:
- 🔍
fzyis a fast and simple fuzzy text finder for the terminal. I wote fzy wanting a faster and more consistent algorithm than was available at the time, other tools have since adopted my algorithm. Fun fact: If you presstto find files in a GitHub repo that’s fzy! - 🖼️
mehis a fast image viewer for X11 using raw XLib.
I dabble in electronics ⚡:
- ⌨️ I designed a USB controller to modernize Model M keyboards.
- ⌨️ I hand wired an ergodox-style keyboard
