Historical weather data is a fascinating topic and someone once told me that 1955 was a memorable summer in the West of Scotland so I checked on-line and found that Glasgow City Council has made it's weather data available under the open government licence.

The Free Software Foundation has published an excellent email self defence infographic explaining how to add an encryption facility to your Email reader using the tools used by Edward Snowden and investigative journalists around the world.

The tools run on Linux, Windows, Mac and I chose Thunderbird as the Email reader as it is cross platform making this post relevent to a wider audience. It will reinforce the instinct that in this day and age and as matter of principle we should only be using devices and software we can pretend to trust

Xubuntu 14.04 - Highly Usable and Simply Brilliant

Xubuntu 14.04 looks and behaves like a solid GNU/Linux based personal computer system and this Long Term Service (LTS) release will become a favourite productive workhorse for many with it's 5 years worth of updates and support.

Xubuntu desktop makes an ideal environment for research and productivity and the pleasingly clean desktop with it's uncluttered menu and productivity tools pinned to the top panel makes it feel almost zen like. It all comes to life when you start using applications in which the open source fonts look stunning when reading text in applications such as web browsers and ebook readers.  

When reading the internal help system and the external information and community pages at the xubuntu and xfce web sites I discovered usability tweaks for improving font sizes and window handling and believe Xfce has potential for users of assistive technologies.

Get Years Extra Service From Your iBook G4

Summary. Upgraded girlfriends iBook G4 from MAC OS X Tiger 10.4.11 to Lubuntu 12.04 and upgraded the memory from 256MB to 1GB. Can't use Adobe Flash browser plugin so installed open source alternative called Gnash and it works good in Firefox when viewing YouTube.

The cooling fans come on a lot but interestingly enough, with Tiger the fans never came on yet the machine would get so hot you could not sit with it in your lap. It is not a problem per se, just a concern and I am always looking to tweak this machines performance.

Easily Install Wordpress as a BitNami Module on XAMPP

After Installing XAMPP for Linux on Ubuntu 12.04 my next task was to install Wordpress and it was real easy because the new setup wizard hides all the gory technical details and sets everything up for you automatically.  

In the past you had to get down and dirty using the command line to modify configuration files and permissions but now you don't have to. The BitNami for XAMPP setup wizard does all the hard work and makes child's play of installing web applications like Wordpress and Drupal.

Install XAMPP for Linux on Ubuntu 12.04 LTS

Update - Aug 2014. The procedure below works with Ubuntu 14.04 and XAMPP 1.8.3. 

Installing popular PHP based web applications such as Wordpress, Drupal and Joomla on top of the XAMPP web development package has become even simpler thanks to a partnership between Apache Friends and BitNami.

BitNami maintains an open source software library where applications are packaged as installable modules which can be downloaded and completely installed using a graphical installer. This will be a huge sigh of relief to anyone who is afraid of using a terminal and manually editing configuration files

I also explain how to create a menu shortcut to the built in XAMPP Control Panel. In a separate article I explain how to Easily Install Wordpress as a BitNami Module on XAMPP
