Let us compete on trustworthiness

This Thursday, 10 jurors were selected in San Francisco. Their verdict – which is expected around mid-December – could change the way Google controls apps and their distribution. This is a result of the suit filed by Epic Games against Google in 2020 over the monopoly held by the Google Play Android app store and its abuse in stifling the competition.

This is something that resonates with F-Droid and the wider FLOSS community. Despite Google’s claims of choice on Android and Google Play, Google still ensures that using all alternatives to Google Play is a second-class experience. It allegedly restricts device makers and wireless carriers that want to sell phones and tablets with the official version of its Android operating system from promoting app stores beside Play. It has also barred developers from offering competing app stores through Play by paying over $1 billion to top developers such as Activision Blizzard and Riot Games in order to keep them loyal to Play through a program it codenamed Project Hug, Epic alleges. Recently, Google Play Services automatically uninstalled the KDE Connect App distributed via F-Droid without any in depth explanation.

To learn more about this, please read this article. F-Droid’s very own eighthave was interviewed to explain the severity of the situation.

Special anniversary release of Arcticons

Donno shared with us the information below

On Nov 8 I’ve released a special Anniversary edition of Arcticons!
Three years ago, I released the first version with around 900~ icons, now we have 8000+

After contributing for months to Frost, a fill-based icon pack. I wanted to create something different (but with the same goal), a line-based icon pack. Because I lacked the technical skills to create an app, so gladly I came across Frost, which was a perfect app to use as a base for Arcticons.

In these three years, the project gained many contributors, and thanks to its low entry level. We’ve managed to do quite a lot in that time, like: Upgrading our app to have more features like icon request support, a variant with black lines and later one with Material You colors , we’ve also created 7000+ icons together, and we’re expanding to Linux too!

This is all possible thanks to the open-source nature of the project, and it’s fantastic community

The official release can be found here and will come to F-Droid in a couple of days. Thanks to Donno for making this happen.

The Apple Network Server’s all-too-secret weapon: PPC Toolbox

Posted on by Michael G
However, there was a secret weapon hidden in ANS AIX most of us at the time never knew about. Built-in to the operating system was a fully Unix-native AppleTalk stack and support for receiving and sending Apple Events, surfaced in the form of Apple’s disk administration tools and AppleShare. But Apple had a much more expansive vision for this feature: full server-client “symbiotic” applications that could do their number-crunching on the ANS and present the results on a desktop Mac. Using the Program-to-Program Communication Toolbox (“PPCToolbox”), and because AIX’s throughput far exceeded anything the classic Mac OS ever could ever handle, an ANS could augment a whole bunch of Macs at once that didn’t have to stop to do the work themselves. Well, today we’re going to write one of those “symbiotic” applications doing something this little Mystic Color Classic could never efficiently do itself — accessing and processing a JSON API over TLS 1.3 — and demonstrate not only how such an client application looked on the Mac side, but also how the server component worked on the AIX side. If you’re lucky enough to have an ANS running AIX too, you can even compile and run it yourself. But before we do that, it might be a little instructive to talk about how the Apple Network Server came to run AIX in the first place. I had no idea the ANS could do this. That’s an incredibly cool feature, and clearly fits in the whole “the network is the computer” idea that dominated the late ’90s.

Ruby 3.3.0-preview3 Released

Posted on by Michael G

We are pleased to announce the release of Ruby 3.3.0-preview3. Ruby 3.3 adds a new parser named Prism, uses Lrama as a parser generator, adds a new pure-Ruby JIT compiler named RJIT, and many performance improvements especially YJIT.

Prism

  • Introduced the Prism parser as a default gem
    • Prism is a portable, error tolerant, and maintainable recursive descent parser for the Ruby language
  • Prism is production ready and actively maintained, you can use it in place of Ripper
    • There is extensive documentation on how to use Prism
    • Prism is both a C library that will be used internally by CRuby and a Ruby gem that can be used by any tooling which needs to parse Ruby code
    • Notable methods in the Prism API are:
      • Prism.parse(source) which returns the AST as part of a ParseResult
      • Prism.dump(source, filepath) which returns the serialized AST as a String
      • Prism.parse_comments(source) which returns the comments
  • You can make pull requests or issues directly on the Prism repository if you are interested in contributing

Use Lrama instead of Bison

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.

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!
  • Significantly improved memory usage over 3.2
    • Metadata for compiled code uses a lot less memory.
    • Generate more compact code on ARM64
  • Compilation speed is now slightly faster than 3.2.
  • Add RubyVM::YJIT.enable that can enable YJIT at run-time
    • You can start YJIT without modifying command-line arguments or environment variables.
    • This can also be used to enable YJIT only once your application is
      done booting. --yjit-disable can be used if you want to use other
      YJIT options while disabling YJIT at boot.
  • Option to disable code GC and treat --yjit-exec-mem-size as a hard limit
    • Can produce better copy-on-write behavior on servers using unicorn and forking
  • ratio_in_yjit stat produced by --yjit-stats is now avaiable in release builds,
    a special stats or dev build is no longer required to access most stats.
  • Exit tracing option now supports sampling
    • --trace-exits-sample-rate=N
  • --yjit-perf is added to facilitate profiling with Linux perf.
  • More thorough testing and multiple bug fixes

M:N thread scheduler

  • M:N thread scheduler was introduced. [Feature #19842]
    • M Ruby threads are managed by N native threads (OS threads) so the thread creation and management cost are reduced.
    • It can break C-extension compatibility so that M:N thread scheduler is disabled on the main Ractor by default.
      • RUBY_MN_THREADS=1 environment variable enables M:N threads on the main Ractor.
      • M:N threads are enabled on non-main Ractors.
    • RUBY_MAX_CPU=n environment variable sets maximum number of N (maximum number of native threads). The default value is 8.
      • Since only one Ruby thread per Ractor can run at the same time, the number of native threads will be used, which is the smaller of the number specified in RUBY_MAX_CPU and the number of running Ractors. So that single Ractor applications (most of applications) will use 1 native thread.
      • To support blocking operations, more than N native threads can be used.

Other Notable New Features

Language

Performance improvements

  • defined?(@ivar) is optimized with Object Shapes.
  • Name resolution such as Socket.getaddrinfo can now be interrupted (in environments where pthreads are available). Feature #19965
    • For this purpose, a pthread is now created whenever calling getaddrinfo or getnameinfo. This incurs some overhead in name resolution (about 2.5x in our experiments). We do not expect the name resolution overhead to be a problem for most applications, but if you observe such, or if you see unexpected affects that you believe are due to this change, please report them.
  • Environment variable RUBY_GC_HEAP_REMEMBERED_WB_UNPROTECTED_OBJECTS_LIMIT_RATIO has been added. Feature #19571
  • Children of old objects are no longer immedately promoted to the old generation in the garbage collector. Feature #19678
  • Support for weak references has been added to the garbage collector. Feature #19783

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 ls, show_source and show_cmds commands.
  • More accurate and helpful information provided by the ls and show_source commands.
  • Experimental autocompletion using type analysis (doc).
  • It is now possible to change the font color and font style in the completion dialog by a newly introduced class Reline::Face (doc)

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