Has Apple sounded the last POST?

Posted on by Michael G
Power-on self-tests (POST) are widely used in electronics, and one of the oldest features of personal computers. Every model of Mac in the past has had its own POST routines, some that have become famous because of the sounds that result, or what’s displayed, from the sight of a Sad Mac to the sound of a car crash. So what happens when an Apple silicon Mac fails its POST? Does it even run them? I never stopped to think about this. The answer is interesting in that it’s not definitive.

Adieu Messenger sur Apple Watch: une nouvelle mise à jour pourrait supprimer l’application.

Une Apple Watch ultra performante

Le groupe Meta a récemment annoncé que Messenger, l’application de messagerie instantanée de Facebook, ne sera bientôt plus disponible sur les montres Apple. Cette nouvelle est une grande déception pour les propriétaires de l’Apple Watch.

L’Apple Watch est considérée comme l’une des montres les plus performantes sur le marché. Dotée d’un capteur de température pour un suivi en temps réel de la santé des femmes, elle offre également une surveillance du sommeil. La montre peut détecter les accidents et appeler les secours en cas d’urgence.

Plus de Messenger sur la montre de la pomme

Messenger ne sera bientôt plus disponible sur les montres de la pomme. Cette application est très populaire et permet aux utilisateurs de communiquer sur les réseaux sociaux. Selon News Day FR, la disparition de cette application serait effective dès la fin du mois de mai.

Les raisons de cette décision radicale

Le groupe Meta n’a pas encore révélé les raisons de cette suppression de Messenger sur les montres Apple. Toutefois, les utilisateurs ne pourront plus utiliser Messenger via leur montre connectée. Cela signifie qu’ils ne pourront plus lire leurs messages ni y répondre depuis leur montre.

Malgré cette triste nouvelle pour les utilisateurs de l’Apple Watch, les notifications Messenger continueront de s’afficher sur l’écran de leur téléphone. Les développeurs de Telegram ont également abandonné leur projet d’application pour les montres intelligentes, ce qui est également une déception pour les propriétaires d’Apple Watch.

Ruby 3.3.0-preview1 Released

Posted on by Michael G

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

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 and RubyVM::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
