Have fun,

When ByteMyCode was crashing because of the traffic load, we started optimizing MySQL. The server had a load of >50 but the processor was all tied up in IOWAIT. We realized that the database was the source of the bottleneck so we increased all of the cache sizes. Now, it is really fast.

A very simple yet very useful function to have around. Especially generating session codes, filenames or new passwords

This little tool is pretty useful for administrators who wear the hat of both system admin and DBA on Linux/MySQL boxes. I wrote it as kind of a joke for our Perl developers, but now I use it just about every day for everything from at prompt hackups to full on table space utilization monitoring scripts.

The snippet has the library script that you can source into scripts that actually do work, as well as a script that uses the functions in the libraries. Anyone who has used the C API should be able to relate to using this script.

It's pretty fast and lightweight. It makes only one external call to mysql and sed per query. The rest is all bash builtins. Requires bash > 3.0

Truncate String

Fixed missing $ sign.

Ping, PingOMatic service for an updated. Requires: The Inutio XML-RPC Library.
