Home
Welcome to tjl2.com! This site has been set up so that I have somewhere to store various useful tips and scripts for work and home.
This site also serves as somewhere for me to have a play around with various web design techniques. Some of this stuff might even be useful for other people.
Current Design
I've just revamped this site to use one of the templates from Open Source Web Design. This particular CSS design was created by Andreas Viklund.
Site Information
Below is a list of some of the things you will find on this site:
- quotawatch - a PHP script used to monitor disk quotas on an Ensim server
- virtDomain.sh - a couple of examples of how to use Ensim's virtDomain customisation scripts
- system admin section - a few notes taken down to remind me how I have solved various Linux-related problems, both at work and home
- Vim Cheat Sheet - proving popular on several Linux forums, this cheat sheet is in PDF format and is ideal for printing out and keeping on your desk!

Please note that this site has a few visual quirks when being viewed in Microsoft Internet Explorer, but nothing critical. I haven't got the patience (or the skills) to fix them all!
