This is a mini howto on installing eAccelerator.

eAccelerator is a free open-source PHP accelerator, optimizer, and dynamic content cache. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.

Summary: Makes your PHP faster.

I’ve got several scripts that have been failing recently due to the high number of files in a directory.

Say for example, my site wide spamassassin Bayes learning script that runs nightly, it has started failing sometimes when a lot of spam has been caught by users.

I’d see

bash: /bin/rm: Argument list too long

A fix would look like this

for i in /your/directory
do
rm -rvf $i
done

find would probably also do the same job.

An unknown Frenchman did a great job at combining and compressing Prototype & script.aculo.us into one ultra-small single Javascript file.

At the time of writing he is on version 1.0.2 which includes Prototype 1.5.1 and Scriptaculous 1.7.1 beta 3
The Protoculous file size is 54.6KB

I had a problem with some slow Ubuntu sources today, instead of changing the whole sources.list manually, I stumbled over Ubuntu Nederland’s Source-O-Matic.
