Thought I’d publish this one, was going to try to use it as some kind of technology worth selling (as most in this sector seem to do with 50 lines of code and an idea nowadays) but in a moment of brilliance remembered what things were like back in the day and what we stood for. Call me a changed man, if you will. You will be happy to hear that I still love and adore using excessive smilies

Easy cpanel WHM or linux remote backup – SSH pull rsync backups for security and integrity using incremental
So you have a cpanel/WHM web server, you have it set to back up all of its accounts. Thats either costing you a lot of FTP bandwidth to send to a remote server, or you are being less than resiliant by only backing up to a local disk. Perhaps you have remote rsync SSH backup already, but havent really thought of the implications of running a SSH/rsync ‘push’ system. This howto is your solution. This howto is not just relevant for Cpanel/WHM servers and you can adapt it to any kind of Linux backups you make.
Easy JBoss AS – Java application server quickstart howto reference
I recently had some interest from a prospective employer who were looking for someone with JBoss and Tomcat experience. Having had extensive use of these systems in my previous role, I figured I would write a quick howto to get people up and running with JBoss in a short time period. Jboss AS (application server) is an open source Java Enterprise Edition (Java EE) based application server, similar to Goldfish. As it is Java based, it runs on multiple platforms and architectures. Jboss features clustering, fail over, load balancing, distributed deployment, deployment API, management API and much more so its a very versatile platform for serving up your applications.
Choices between freesat receivers, skytv, digiboxes and digital tv tuner card
It seems hard to find information in one place that gives an overview of the different free satellite TV options available in the UK, so here is our guide entitled ‘choices between freesat receivers, skytv, digiboxes or digital TV tuner card’ to try to give you an overview of the options available and their initial costs. We try to cover all the options open to you for UK digital TV reception from the main group of satellites serving English language programming. The guide is aimed at the UK marketplace, although many free to air channels can be received across most of Europe with the correct hardware (normally just a larger dish).
Recovering a lost Mysql root password
The problem
Recently I had to recover a lost MySQL root password from a system I dont very often use. Somewhere in the mists of time I must have forgotten it.
List, backup or Restore installed packages on Debian and Ubuntu
The problem
Many a time I have re-installed my system from scratch or created a new system, but get sick of continually installing the same packages over and over. Its annoying when 2 or 3 months down the line you want to use a program you used to have (or have on another system) only to find its not yet installed. Sure, an apt-get install only takes a few minutes for a single piece of software, but that’s a few minutes a geek like me could better spend doing something productive.
Encrypting your Ubuntu swap partition
What is swap?
Even if you encrypt data on your partitions, something that is often overlooked is your swap partition. Swap is where linux ‘swaps’ programs (and their stored data) from physical system memory onto the hard disk when they are not used. When those programs become used again, the system ‘swaps’ them back into memory. This approach can allow you to run more programs than you have RAM for, at the cost of delay – for example when programs are swapped back into RAM from disk.
OGG to MP3 streaming howto – icecast and shoutcast
If your station DJs only have the ability to broadcast in OGG/Vorbis but your listeners listen mainly in MP3 via shoutcast (for example, Traktor can only broadcast in OGG), this howto guide is for you as it shows how to seamlessly integrate and transcode an Ogg (icecast) broadcast to a shoutcast (mp3) broadcast using some off the shelf, free technology. The way the system works is using the feature in icecast to call programs when a source connects or disconnects. These scripts then invoke (or terminate) a custom perl program which uses ogg123 to receive the ogg stream from the icecast server, pipes it into the lame program to convert to MP3 and then uses the libshout bindings to send the stream to the Shoutcast MP3 server. While this will work with any linux distribution, in this howto I use the Ubuntu and Debian ‘apt-get’ system to install the various required components. If you use a different distribution you should substitute any apt-get commands with your distribution specific package manager (or build from source if you are into punishment).
