Another simple way to block trackers

In my previous post, I covered the excellent Adblock Plus add-on for you browsers.  There is another equally good product which also blocks  trackers and cookies.


Ghostery can be installed in Firefox and Google Chrome as well as Mozilla (Firefox) derivatives like Seamonkey.

Before starting, you shouldn’t just install Ghostery because you read something on the internet. Continue reading Another simple way to block trackers

Updating eGroupware from 1.8.004 to 1.8.005 on FreeNAS

Updating eGroupware in a FreeNas Jail

The version of eGroupware that is packaged in the FreeBSD ports tree has a base phpgwapi of 1.8.004 (as at 30 December 2013).  There has been an update to the base package and this is now at version 1.8.005. The change log for the update is here.

This mini-guide describes the steps to update eGroupware running in a FreeNAS Jail

Before starting I would highly recommend reading the eGroupware Update Instructions found here. This post follows the steps there, but records the installation in to a FreeNAS jail, which isn’t covered in the documentation directly.

The Hidden Math(s) in The Simpsons and Futurama

This is really related to anything in particular, but a few weeks ago in the Observer, Simon Singh (a really excellent science communicator BTW) wrote a piece about the maths jokes in The Simpsons (See The Simpsons Secret Maths).

Today on the BBC web site, he’s followed it up with another piece, this time about Futurama (see Futurama and Maths). This is quite a bit shorter than the Observer piece.

The brief biography of the mathematician Srinivasa Ramanujan (1887-1920) is fascinating.  He achieved so much before his early death at 32. due to tuberculosis.

I’d recommend any Simpsons or Futurama fan look at these – it’ll give you some ammunition against those who claim cartoons are responsible for  “dumbing down” TV.



The evolution of my system Part 1.

Since I’ve been writing about bits and pieces of my set up, I thought it might be useful to give it a bit of context.

I’ve been running email on my home system for years, starting with Sendmail and Pine then moving onto a more sophisticated system giving group-ware functionality.

A  purchase of a digital camera 13 years ago (followed by several generations of replacement cameras and the ubiquitous mobile phone) has meant that a huge number of family photos were now only in digital format, and only stored on one disk.

A project to digitise my CD collection to reduce the clutter in the house also left various audio files sitting on a couple of machines and my phase 2 project to do the same for my DVDs put on hold.

The mail system was adequate, but I was feeling more uneasy about the storage situation, especially the photos.

The cost per MB  has continued to fall, so my initial project was to build a NAS.
