This entry describes simple techniques to fulfill the JavaScript compiler optimization process which results in faster running code. Especially in games you immediately notice frame drops and when the garbage collector has to hit in with a big stack of work to do.

xkcd 1313: Something is Wrong on the Internet!

Tue, 07 Jan 2014 01:41:00 +0100

I found that the rollover text, “/bu|[rn]t|[coy]e|[mtg]a|j|iso|n[hl]|[ae]d|lev|sh|[lnd]i|[po]o|ls/ matches the last names of elected US presidents but not their opponents.”, is obviously false. After all there are several last names (like “Nixon” and “Bush”) that denote both elected presidents and opponents. So no regular expression could both match and not match “Nixon”.

So that got me thinking: if we ignore names that are both winners and losers, what regular expression does cover the winners and not the losers? And let’s try to find a short one, although perhaps not the very shortest.

localepurge es una herramienta que elimina los archivos de traducción que no necesitemos. Después de instalarlo, nos pedirá que seleccionemos qué idiomas queremos conservar:

en_US
en_US.ISO-8859-15
en_US.UTF-8
es
es_ES
es_ES@euro
es_ES.UTF-8

Después de instalarlo, lo ejecutamos:

$ sudo localepurge
Total disk space freed by localepurge: 26552 KiB

Cada vez que instalemos un nuevo paquete de los respositorios se ejecutará automáticamente, por lo que no tendremos que volver a preocuparnos.
