Design of LuaJIT 2.0 (2009)

> I cannot guarantee it to be free of third-party IP however. In fact nobody can. Writing software has become a minefield and any moderately complex piece of software is probably (unknowingly to the author) encumbered by hundreds of dubious patents. This especially applies to compilers. The curent IP system is broken and software patents must be abolished. Ceterum censeo.

Somewhat related, Apple seems to be filing dubious patents on Swift. Discussion from a couple of days ago: https://news.ycombinator.com/item?id=18997302

I use luajit in a few places in my own stack (Redis, Kyoto Tycoon) and appreciate how magically fast it is. I have no idea how to approach a post like this. SSA, FOLD, it's all Greek to me. I feel pretty satisfied swapping an n^2 loop for an nlogn implementation, but this is a completely different level. Grateful for this library and for the fact that I don't have to understand it to use it (it's good to be humbled).

Also anecdotally, I think raptorjit is a kind of next incarnation of luajit. https://github.com/raptorjit/raptorjit

Actually, found this on the raptorjit readme, a list of helpful optimization resources: https://github.com/raptorjit/raptorjit/blob/master/README.md...
