  • Project mention: Boehm Garbage Collector | news.ycombinator.com | 2024-01-21


    Due to the nature of web engine workloads migrating objects to being GC'd isn't performance negative (as most people would expect). With care it can often end up performance positive.

    There are a few tricks that Oilpan can apply. Concurrent tracing helps a lot (e.g. instead of incrementing/decrementing refs, you can trace on a different thread), in addition when destructing objects, the destructors typically become trivial meaning the object can just be dropped from memory. Both these free up main thread time. (The tradeoff with concurrent tracing is that you need atomic barriers when assigning pointers which needs care).

    This is on top of the safey improvements you gain from being GC'd vs. smart pointers, etc.

    One major tradeoff that UAF bugs become more difficult to fix, as you are just accessing objects which "should" be dead.

  • multipass

    Multipass orchestrates virtual Ubuntu instances

  • Project mention: Linux virtual machines, with a focus on running containers | news.ycombinator.com | 2024-05-27

    Since we're here. What do people use when they need to test their software installs well on naked Ubuntu Server of some version? To not do manual setup in VMWare, can be Linux-only.

    I've found Multipass https://multipass.run/ by Canonical and I wonder if anyone recommends it.

  • wrench

    practical embedded script interpreter (by jingoro2112)

  • Project mention: Kolibri OS: fits on a floppy disk, programmed using interrupts | news.ycombinator.com | 2023-11-30

    Doesn't look promissing, sorry. Was looking and looking, but where is the GUI-based OS?

    Nowadays we can use LVGL and C++ to write apps, or run script based C code using interpreters like Wrench: https://github.com/jingoro2112/wrench

    What I'm missing is an GUI-based OS like Kolibri to launch apps.
