TruffleRuby can now run C/native extensions in parallel, just like Ruby code runs in parallel in Threads on TruffleRuby!
Native extensions need to opt in with rb_ext_ractor_safe(true) or rb_ext_thread_safe(true). Many gems already do that.
See https://github.com/oracle/truffleruby/blob/master/doc/user/thread-safe-extensions.md for more details.

My thoughts on the new #Ruby namespaces (https://bugs.ruby-lang.org/issues/21311) in one sentence:
Sub-interpreters are similar to Namespace + Ractor but with proper isolation, full compatibility, linear scaling and clear semantics.

Compatibility is a key argument here, Ractor can't use most gems.

@galtzo i.e. https://github.com/oracle/truffleruby/blob/graal-24.1.2/README.md#current-status the 24.1 docs say 3.2

@galtzo Are you looking at master branch docs? Those reflect the upcoming release. Pretty sure we never had such a mismatch in TruffleRuby.

@getajobmike Is it inspired or based on https://iliabylich.github.io/ruby-ractors-and-lock-free-data-structures/intro.html ? (It looks like so)
It would be nice to have a mention in the README about it.

TruffleRuby 24.2 is released!🚀🎉
It uses the new Java Foreign Function and Memory API when used in JVM mode to speedup C extensions like sqlite3, trilogy and json by 2 to 3 times!
It redesigns encoding negotiation so many String operations are now faster.
It updates to Ruby 3.3 and contains many compatibility and bug fixes.

@getajobmike What about sending some special message like :stop or :exit to the Ractor? Like what people used to do before Queue#close was added.

latest from @nelhage has way more plot twists than i expected! https://blog.nelhage.com/post/cpython-tail-call/

If I were to recommend only three Ruby articles published last week to read, here is what I would recommend:

Benchmarking Ruby Parsers by @eregon
Next Generation Out of Band Garbage Collection by @byroot
Rails with Postgres - Fuzzy Searches by Bill Tihen

#ThreeRubyLinks #ShortRuby #Ruby #Articles

Ruby 3.4's new `prism` parser is 2.5x faster than the old `parse.y` parser, according to @eregon. Nice work!

TruffleRuby 24.1 is released!🚀🎉 It updates to Ruby 3.2.4, gets a lot of compatibility and bug fixes, and significant performance improvements: https://github.com/oracle/truffleruby/releases/tag/graal-24.1.0

The main performance improvement is a complete review of all 100+ inline caches to ensure they use splitting to keep these inline caches as fast and monomoprhic as possible. You can find more information about splitting and inline caches in this talk: https://rubykaigi.org/2023/presentations/eregontp.html

The Steam Families feature is out of beta:

https://store.steampowered.com/news/app/593110/view/4149575031735702628

I'm still amazed such a pro-consumer move was made. Most media companies have been using digital as a way to restrict rights in ways physical never could.

Steam is addressing my largest issue with digital games: having to buy multiple copies when only one family member is playing at a time. They've made purchasing & license management easier, too. I'm inclined to sell to switch the kids from Nintendo Switch to Steam Deck.

@nirvdrum Interesting, do you have a concrete example? Does rb-sys actually duplicates logic of some C-API fonctions ?

@john "Now it’s Ruby that’s 5 times faster than Crystal!!!"
Than crystalruby*, it's not fair to consider that to be Crystal's performance (also the Crystal version should use a while loop too to be fair, though that may not change anything for Crystal).

@john @phillmv @truffleruby TruffleRuby already optimizes this very well and makes all 3 variants the same performance, and 45 times faster than YJIT: https://gist.github.com/eregon/8e104d291ca64d0834b580d18b837059#file-results-txt

TruffleRuby 24.0 is released!🚀🎉 It ships with 3 major features:
* Native extensions are executed natively for faster warmup
* Near-complete support for Ruby 3.2 (97.4% of specs)
* Full support for the Ruby syntax by adopting the Prism parser
