Many months ago there was a PHP competition to make the smallest script to extract all the links from a document. I’ve lost a link to the actual site, but the rules and conditions were set up expecting everyone to solve the problem with regular expressions. In my opinion relying on regular expressions [...]

Manual optional type checking for PHP functions

Pankaj Kumar has a slightly disturbing look at memory usage in PHP.
Each element requires a value structure (zval) which takes 16 bytes.
Also requires a hash bucket - which takes 36 bytes. That gives 52 bytes
per value. Memory allocation headers take another 8 bytes*2 - which
gives 68 bytes. Pretty close to what you have.

Javascript is both infuriating and awesome at the same time. I don’t think I’ve ever speant so much time tracking down annoying bugs (even compared to PHP), yet at the same time it makes functions like the one below very simple to write.
For reference, the below code returns a `getter` method that we use [...]
