Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      .@RichFelker My basic complaint with Android is it's "the revenge of BeOS". They forced Java on developers, just like BeOS forced C++ APIs.

      .@RichFelker Two basic complaints with BeOS in 1997: 1) the fragile base class problem, which they solved by padding public C++ classes.

      .@RichFelker 2) BeOS forced developers to use threads, which led to tons of race conditions. Each BWindow needed its own event loop thread.

      .@RichFelker So my impression of Android is: ex-Be devs (Travis Geiselbrecht, Dianne Hackborn, et al) rewrote BeOS in Java instead of C++.

      .@RichFelker The major architectural difference was to use a single UI event thread, just like every other GUI API that became successful.

      .@RichFelker My major complaint with Android is that all apps are forced to run the Java VM in user space to interface with the system.

      .@RichFelker Consequently, C++ native development with exceptions & RTTI was only properly supported starting in Android Gingerbread (2.3).

      .@RichFelker Android 2.3 was the first version that allowed games to be written entirely in C++, but the JVM still runs in the background.

      .@RichFelker I don't like Java very much. I prefer Apple's evolution of Objective-C & the way they integrated its newer features into Swift.

      .@RichFelker But I don't have any complaints with Android's C/C++ toolchain per se. It's only the Java requirement for apps that annoys me.

      @jhamby Bionic is rather awful, gratuitously conflicting with POSIX, and repeats lots of historical mistakes like 32-bit off_t...

          @jhamby Bionic was not designed to be a good/correct/usable libc but a minimal shim to run a JVM on top of. :-(

          .@RichFelker So very true. Android was also "the revenge of Danger", since so many early engineers came from there. https://en.wikipedia.org/wiki/Danger_Hiptop …

          I was an intern at Be for 6 months in 1997, but I worked at Danger from 2005–2009. Android is basically open-source Danger OS. @RichFelker

          The same engineer who designed Dalvik also worked on Danger's JVM (with a similar proprietary bytecode) before joining Google. @RichFelker

          .@RichFelker Dalvik's bytecode was designed for fast interpretation by an optimized interpreter, which Danger and early Android both used.
