# Issue #806: A Rails blog app in a ~500KB binary — Ruby Weekly

**[Ruby Weekly](https://daily.dev/sources/rbywkly)** · 3 min read · 0 upvotes · 0 comments

## Summary

Ruby Weekly issue #806 covers a range of Ruby ecosystem news. The headline story is an experiment compiling a Rails blog app to a ~500KB binary using Spinel (Matz's AOT Ruby compiler) and the Roundhouse compiler, serving the app in just 12MB of RAM. Other highlights include a proposal to add parallel sweeping to Ruby's GC (showing ~3.64% runtime improvement), the json gem 2.20 release with non-recursive parsers and a new ResumableParser, a pure Ruby X11 terminal emulator, and several library releases including RubyGems/Bundler 4.0.15, mruby/c 4.0, Rails Event Store 3.0, and Grape 3.3.
