So on part one, we managed to compile kalk with emulator, and generated ArchLinux package to install on our PinePhone. However, emulator is slow, and compiling with emulator isn’t cross compile. Today, we’ll be using real cross compiler to build kalk package.

PinePhone has been out for over one year now. In the last year, KDE plasma mobile saw rapid progress. We’ve developed almost all utility apps you’d have on iOS and Android. And actions like flashlight, screen capture also get added to top panel. What’s more, the launch screen and app drawer only get better.

One of the major feature of Ruby 3.0 is the introduction of ‘ractor’. Ractor is a new concurrent abstraction for Ruby. Unlike Ruby threads, ractors can run in parallel. Due to the Ruby Global Virtual Machine Lock(GVL), even each Ruby thread is mapped to native thread, there can only be one active thread running. But after the introduction of ractor, there can be multiple GVL, each ractor has one. That’s why ractors can have parallel execution.
