SpamAssassin site wide spam learning
SpamAssassin is great. I wouldn't run a mail server without it. Obviously it isn't 100% from day one, thats where Bayes learning comes in. Yes, it auto-learns, but some times we want to convince it a little more.
Anonymous apache & PHP
Like to be conspicuous? Like me.
Then use the ServerTokens and expose_php options. On a production web server I generally set these two options, pretty much stops and zero day hack attempts and other such nonsense
bash – Argument List Too Long
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.

Converting XLS to CSV. Simple, eh? Well, sorta.
I hate problems that can be solved really easily. (With a totally different set of tools). I needed to open Excel (XLS) files in PHP. Simple enough you think, IF you are using Windows.
IF I was using Windows, I would have a bunch of options open to me, I could use PHP's COM & .NET functions. Or PHP's ODBC functions. Or a selection of classess from PHP Classes.
NTLM Authentication (Active Directory) on Apache (Linux)
Here is a quick guide to enabling NTLM authentication for Apache 2.
I generally use Ubuntu, so I am a heavy apt-get'er, but I prefer to build my apache from source.
