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…

First look at Clojure.core.typed
I just heard that core.typed is ready for production. Which is great timing because I'm working with a new team and they like types.

On the Cleverness of Compilers
The “Sufficiently Clever Compiler” has become something of a trope in the Lisp community: the mythical beast that promises language and interface designers near-unlimited freedom, and leaves their output in a performance lurch by its non-appearance. A few years ago, I was young enough to join a research project to…

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…

Ruins of forgotten empires: APL languages
One of the problems with modern computer technology: programmers don’t learn from the great masters. There is such a thing as a Beethoven or Mozart of software design. Modern programmers seem…

LLVM Intermediate Representation is better than assembly
The crucial part is IR. It's a common language that sits between the high-level program and the low-level backend . IR is used to express high level concepts and is specific enough that any backend can produce a fast machine code.

PyPy.js: First Steps
I've been spending a lot of time in JavaScript land lately. It's not totally unexpected – when I first applied for a job with Mozilla, I was warned only semi-jokingly that "they hire all the best Python programmers and then force them to write JavaScript". I've no deep love or hate for it as a language, but JavaScript…

JavaScript Isn't Scheme
It seems like I can’t spend five minutes on reddit these days without someone playing the JS-is-Scheme is card . I see everything from the innocuous, “JavaScript has a lot in common with Scheme”, all the way up to, “JavaScript is basically Scheme.” This is basically crazy. Or, at least it has a lot in common with…
