Welcome to techheadz tutorials
Techheadz offers a selection tips and tutorials in Apache, CSS, HTML, Javascript, Linux, MySQL, Perl, PHP, Ubuntu and Windows.

The site was started with the intention of providing my own online reference, something I could fall back on if I ever encountered the same problem twice. It has been interesting to see the site grow over the last few years, as I have added more tips and tutorials to the database.

It is also interesting to see that other people are using the site, and hopefully using it to solve their own IT problems.

Don't forget if you run your own Linux or other computer related website that may be of interest to our users, why not add your Linux link.
You website will be added to our link page and provide some alternative content for our visitors. Alternatively why not join our twitter feed.
