Rambling On [PHP] Internals
This is a post that I didn’t want to write. Actually, it’s a post that I still don’t want to write. But I find myself in a situation where I feel that I have to say something. So I’m going to just ope

Trampolines in JavaScript
A trampoline is a loop that iteratively invokes thunk -returning functions ( continuation-passing style ). A single trampoline is sufficient to express all control transfers of a program; a program so expressed is trampolined, or in trampolined style; converting a program to trampolined style is trampolining…

I hate the Pumping Lemma
I hate the Pumping Lemma for regular languages. It’s a complicated way to express an idea that is fundamentally very simple, and it isn’t even a very good way to prove that a language is not regula…

Callbacks are Pretty Okay
Among the many proposed solutions, one of them strikes me as particularly clean: "asynchronous wait" or "wait and defer". iced-coffee-script had this a while ago. Kal just debuted with an identical solution, only differing in syntax. Supposedly LiveScript supports this with "backcalls" .

Destructuring Assignment in ECMAScript 6
I have seen this question come up a few times, and unfortunately, people usually don't find an answer, give up, and don't test their source maps. However, testing source maps isn't too hard if you are using Node.js and the mozilla/source-map library. If you aren't using Node.js and the mozilla/source-map library, you…
