Ruby 3.3.0-preview1 Released
We are pleased to announce the release of Ruby 3.3.0-preview1. Ruby 3.3 adds a new pure-Ruby JIT compiler named RJIT, uses lrama as a parser generator, and many performance improvements especially YJIT.
RJIT
- Introduced a pure-Ruby JIT compiler RJIT and replaced MJIT.
- RJIT supports only x86_64 architecture on Unix platforms.
- Unlike MJIT, it doesn’t require a C compiler at runtime.
- RJIT exists only for experimental purposes.
- You should keep using YJIT in production.
- If you are interested in developing JIT for Ruby, please check out k0kubun’s presentation on Day 3 of RubyKaigi.
Use Lrama instead of Bison
- Replace Bison with Lrama LALR parser generator [Feature #19637]
- If you have interest, please see The future vision of Ruby Parser
YJIT
- Significant performance improvements over 3.2
- Splat and rest arguments support has been improved.
- Registers are allocated for stack operations of the virtual machine.
- More calls with optional arguments are compiled.
Integer#!=
,String#!=
,Kernel#block_given?
,Kernel#is_a?
,
Kernel#instance_of?
,Module#===
are specially optimized.- Instance variables no longer exit to the interpreter
with megamorphic Object Shapes.
- Metadata for compiled code uses a lot less memory.
- Improved code generation on ARM64
- Option to start YJIT in paused mode and then later enable it manually
--yjit-pause
andRubyVM::YJIT.resume
- This can be used to enable YJIT only once your application is done booting
- Exit tracing option now supports sampling
--trace-exits-sample-rate=N
- Multiple bug fixes

The Cyber Resilience Act introduces uncertainty and risk leaving Open Source projects confused
What might happen if the uncertainty persists around who is held responsible under the Cyber Resilience Act (CRA)? The global Open Source community is averse to legal risks and generally lacks access to counsel, so it’s very possible offers of source code will simply be withdrawn rather than seeking to resolve the uncertainty.

LIVRO DIGITAL-Como treinar seu pastor alemão!
Para treinar seu pastor alemão, comece com exercícios básicos de obediência, como sentar e ficar. Em seguida, ensine comandos mais avançados, como “vem” e “deixa”. Use recompensas positivas, como petiscos e elogios, para encorajar o bom comportamento. Faça sessões de treinamento curtas e frequentes, e seja consistente em seus comandos e expectativas. Além disso, certifique-se de exercitar seu pastor alemão regularmente e oferecer estímulos mentais para manter a mente dele ativa. Busque a ajuda de um profissional de treinamento de cães, se necessário.
