I recently started using the automated backup system Deja Dup which makes it very easy to set up automated, encrypted, incremental backups using the Duplicity back-end.

In this article I describe how to configure Z-Push to use a Roundcube contacts database to allow synchronisation of contacts on a smartphone or tablet using ActiveSync.

My past self would be sad and amazed if he could see me how lazy I’ve become. I have a printer plugged into my laptop which runs on Xubuntu but I wanted to be able to print from my iPad while I’m on the sofa downstairs.

I’ve had an HTC Desire 601 for a few months now and have generally been very happy with it. Generally the battery has lasted about 30 hours with minimal use, but last week HTC released a software update which meant battery the battery life went to about 6 hours without me even using it!

In this post, I detail how to setup Nagios to monitor a Windows machine via NSClient++

Prerequisites:

• A working Nagios install, configured on a server with a fixed IP
• The latest NSClient++ MSI Installer

NOTE: At time of writing, the latest version of NSClient++ is 0.42 and is recommended as 0.41 has issues with binding to IPv4 addresses

At the moment I’m working on some maths code written in a combination of standard Python and its mathematical superset, Sage. The code is fairly computationally expensive (it’s essentially a brute force search for chemical reaction networks that are monotone). Consequently, after getting the code working as a proof-of-concept, I wanted to compile it to C using Cython to get a bit more speed out of it. I found the documentation on converting Sage and Python scripts to Cython a bit vague, particularly when it comes to combining the two, so this article gives step by step instructions based on my findings.

I just gave a presentation on Mozilla's new JPEG-improving project mozjpeg as part of my 'image technology' module at university. We had to chose an emerging technology to research and present to the class in pairs.

In this post, I describe how to upgrade a Moodle installation from one major version to a newer one using the command line and git.

In this post, I present a function to calculate the second additive compound of a square matrix using the symbolic algebra program Maxima.
