Hacker News with Generative AI: Virtual Machines

The Curious Case of Beam CPU Usage (2019) (stressgrid.com)
While benchmarking Go vs Elixir vs Node, we discovered that Elixir (running on the BEAM virtual machine) had much higher CPU usage than Go, and yet its responsiveness remained excellent. Some of our readers suggested that busy waiting may be responsible for this behavior.

JEP 483: Ahead-of-Time Class Loading and Linking (openjdk.org)
Improve startup time by making the classes of an application instantly available, in a loaded and linked state, when the HotSpot Java Virtual Machine starts. Achieve this by monitoring the application during one run and storing the loaded and linked forms of all classes in a cache for use in subsequent runs. Lay a foundation for future improvements to both startup and warmup time.

Implementing an Intermediate Representation for ArkScript (lexp.lt)
ArkScript is a scripting language, running on a VM. To accomplish this, we had (as of September 2024) a compiler generating bytecode for the virtual machine, receiving an AST from the parser (and a few other passes like name resolution, macro evaluation, name and scope resolution…).
