Allow me to reintroduce myself, my name is MagLev
summary
MagLev 1.0 runs Ruby on a GemStone/S Smalltalk VM and ships a built‑in object database that persistently stores live Ruby objects (classes, procs, threads) via persistence by reachability and transaction commits. Examples show a Sinatra blog with no migrations, a 35‑line distributed worker queue using persisted procs with simple retry on commit failure, and a leaderboard implemented as Ruby sorted sets. Current release targets Ruby 1.8.7 with work toward 1.9/2.0; stone storage scales by adding extents rather than sharding.
