Back in Erlang Today…
…and, I have to say, for writing async/parallel code, it’s just awesome. I sometimes think I’m drinking the shiny new technology-flavored kool-aid when I talk about Erlang (which kool-aid I desperately try to avoid, personally), but then someone gives me a task like:
Write a chunk of code to load balance HTTP requests between two identical cache servers, failing over to one if the other goes down.
And as I write it in Erlang, it’s just such a perfect fit.
Oh, and for any regular readers of this blog, I actually caught myself today saying “Hey, records are working really well right here.” That’s right, records. I know. After all the abuse I’ve heaped on them. Built-in dicts are still very much missing from the langauge, don’t get me wrong, but records work pretty well for holding state inside gen_server loops.
