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…).

Mkfs.fat on Linux vs. OS/2 2.1 (uninformativ.de)
I often run VMs with old operating systems in them, like OS/2 2.1. Exchanging data with these VMs is a bit tedious, because there's usually no networking. I can basically only use floppy images or HDD images. For the longest time, I used a 256 MB disk image that I once created manually under MS-DOS. This usually worked, but being confined to a fixed size is not that great.
