We're proud that The Register uses valid XHTML and CSS on its pages (give or take the odd hiccough involving over-enthusiastic advertisers or eager-to-get-a-scoop journalists — if you spot any problems please let our webmaster know.)

The site is built using a custom content management system which is written in Perl and filters its input through HTML Tidy. The pages are generated using the GNOME libxslt library.

The webservers are running Apache, with MySQL for the back-end database and the search engine. Our web applications (search, reader comments, Reg Whitepapers, Reg Events, etc) are all built on mod_perl. All the software runs on Debian GNU/Linux, chosen for its stability, reliability, flexibility, and especially for its superlative support of remote package management and upgrades.

The scripts, HTML, and CSS were created and edited using a combination of Vim, GNU Emacs, and Mozilla Firefox’s EditCSS extension. Simon Myers, Aaron Crane, Geoff Richards, and Hannah Dee at GBdirect did the typing (and thinking).

The hardware lives at Rackspace, where it is lovingly cared for by their Fanatical Support.
