Time for an introduction, I guess:

I'm a student, software developer and hardware/semiconductor enthusiast.

My main projects are #spiderfire, a JavaScript runtime that uses @SpiderMonkey instead of v8 like other runtimes and my small personal website.

I'm particularly interested in logic process technology, CPUs and GPUs, though I do dabble in other subdomains too.

#SpiderMonkey has this minor optimisation for strings where, instead of copying, the data is leaked temporarily, and you're responsible for freeing it when the GC tells you that its safe.

This is fine given that JS Strings are immutable.
These are referred to as External Strings.

I'm thinking about implementing this for #spiderfire, just because I can really, not because anyone will ever use it.
