Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Rust-Written Linux Scheduler Showing Promising Results for Gaming Performance
eBPF doesn't run in user space in the context of eBPF in the linux kernel. It's verified so that the kernel can be sure it won't loop forever and then gets JIT'ed and run in kernel space.
There are some user space BPF vms like https://github.com/iovisor/ubpf and Solana.

Ask HN: Recommendation for general purpose JIT compiler
The usual recommendation have been given. Now for more touristic approach what I would like to use if given excuse and time. All those options are mostly written in C:
- QBE [1] - small compiler backend with nice IL
- DynASM [2] - IIUC the laujit's backend, that can and is used by other languages
- uBPF - Userspace eBPF VM. Depending on your DSL the eBPF toolchain could fit your use-case, but this would probably be the biggest excursion.

how to build eBPF learning env on my Mac
There are eBPF-specific userspace implementations you can consider looking into but right now the best support for bpf would be the linux kernel so if the goal is learning you'll most likely want to run linux in a proper virtual machine (e.g. Qemu, VirtualBox, Parallels, etc.)

Bytecode for a Register Machine
This may be entirely irrelevant to what you are looking for, but a good widely used finite register-based VM is the eBPF VM in the Linux Kernel. The IOVisor uBPF project (https://github.com/iovisor/ubpf) is a version of the VM in user space.
