Wendy’s opens in Leeds. The American burger chain’s new spot at the corner of The Headrow and Briggate is part of its plans to have 45 restaurants in the UK by the end of the year and follows openings in Sheffield and Lincoln in recent months.

A frequent question in the open source CMS world is a variation of: “Which is better, Drupal or WordPress?” 
There’s not a simple answer to the WordPress vs Drupal question. Many have a strong bias towards one content management system or the other, but often, staunch opinions on the subject are based on a few cursory facts or outdated information.

Following last week’s beta, version 2.0.0 of re2 (Ruby bindings to Google’s RE2 “fast, safe, thread-friendly” regular expression library) is now available from RubyGems. Unlike version 1, it no longer requires the underlying RE2 library to be installed separately as it is now vendored with the gem and precompiled, native gems are available for Linux, Windows and macOS.

We are pleased to announce the release of Ruby 3.3.0-preview2. 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

• Major performance improvements over 3.2
  • Support for splat and rest arguments has been improved.
  • Registers are allocated for stack operations of the virtual machine.
  • More calls with optional arguments are compiled.
  • Exception handlers are also compiled.
  • Instance variables no longer exit to the interpreter
    with megamorphic Object Shapes.
  • Unsupported call types no longer exit to the interpreter.
  • Integer#!=, String#!=, Kernel#block_given?, Kernel#is_a?,
    Kernel#instance_of?, Module#=== are specially optimized.
  • Now more than 3x faster than the interpreter on optcarrot!
• Metadata for compiled code uses a lot less memory.
• Generate more compact code on ARM64
• Option to start YJIT in paused mode and then later enable it manually
  • --yjit-pause and RubyVM::YJIT.resume
  • This can be used to enable YJIT only once your application is done booting
• ratio_in_yjit stat produced by --yjit-stats is now avaiable in release builds,
  a special stats or dev build is no longer required.
• Exit tracing option now supports sampling
  • --trace-exits-sample-rate=N
• More thorough testing and multiple bug fixes

Other Notable New Features

Other notable changes since 3.2

IRB

IRB has received several enhancements, including but not limited to:

• Advanced irb:rdbg integration that provides an equivalent debugging experience to pry-byebug (doc).
• Pager support for commands like ls and show_cmds.
• More accurate and helpful information provided by the ls and show_source commands.

In addition, IRB has also undergone extensive refactoring and received dozens of bug fixes to facilitate easier future enhancements.

Stdlib compatibility issues

ext/readline is retired

• We have reline that is pure Ruby implementation compatible with ext/readline API. We rely on reline in the future. If you need to use ext/readline, you can install ext/readline via rubygems.org with gem install readline-ext.
• We no longer need to install libraries like libreadline or libedit.

What is Ruby

Ruby was first developed by Matz (Yukihiro Matsumoto) in 1993,
and is now developed as Open Source. It runs on multiple platforms
and is used all over the world especially for web development.

Can you really do 3D printing from OpenBSD? Cue suspenseful music
whilst I formulate my answer, which is: Yes.

If you aren’t familiar with the 3D printing process, it’s divided
into several steps, vaguely analogous to writing, compiling and running
a program in a compiled language.

The GNU System is turning forty. In honor of this event, the Free

The latest Haiku activity report is here, covering the month of August, and it’s a massive laundry list of fixes and improvements, but I couldn’t find any major big ticket features or fixes. August also happens to bring the first two final Google Summer of Code reports – porting .NET to Haiku, and improving various parts of Icon-O-Matic, a vector drawing program designed specifically for working with Haiku’s vector icon format. Also of note is that the main Haiku CO is down at the moment, but should be back up soon.
