Luke Gorrie is one of the guys that started SLIME.

Most of us still program with a slow edit-compile-test loop and that makes me sad.

Everyone should try SLIME once (or at least a language with a great REPL).

Andy Wingo writes about Guile in such a high-level that a layman can't make much of it (and thats ok).

I'm a fan of those guys...

That is pretty impressive.

BPF also allegedly has a JIT:

But I understand it is effective for x86-64 architecture only. It can also be disabled and enabled with:

sysctl net.bpf.jitter.enable=0|1

NetBSD has a more portable jit for BPF now (not every architecture yet).

I'd love to hear more details from anyone thats had a chance to deploy this alongside a high-throughput snabb switch .. I must confess to having a bit of a crush on the snabb codebase, its probably one of the most interesting projects I've seen utilizing the LuaJIT lately. Anyone got time to give us a report on it?
