October 20 2014: BarCamp Manchester, GPIO, GIMP and permissions

After a period of general chat Brian talked about his visit to the BarCamp Manchester where he had given two talks and heard an interesting talk about building a house with straw bales; it needs to be rendered with lime and have stakes to support it.

This led into a discussion of security, passwords and the iCloud breach.

CiviCRM: managing volunteers and much more

Businesses have lots of Customer Relations Management software to choose from; the voluntary sector has one, tailored for the needs of voluntary organisations from the outset. Unlike most similar software, it is not a free-standing program but runs as an extension to Drupal (for which it was originally designed), Joomla or Wordpress. Moreover, you can select the components of CiviCRM that you need. So you don’t have to burden yourself installing features that you are never likely to need.

• has a documentation project.

June 16th 2014 Art, Encryption and Aviation

Without our regular note taker present, the minutes from June’s meeting is a little lacking.  We spoke about Leeds Art Crawl, Flight Radar, Truecrypt, and secure VoIP whilst attempting to install Android on an EePC (and getting slightly further in doing so than WYLUG).

May 19th 2014 CLI discoveries and No place to hide

Brian presented a number of recent discoveries:

• powertop which marks as ‘bad’ processes where power consumption can be reduced
• reptyr which allows you to transfer a running process from one parent to another

Web enabled PDFs

When Adobe created the PDF (Portable Document Format) in 1993, it was aimed at large companies who wanted to distribute documents without having to bother about whether those who received them had particular fonts on their computers. While the software to create a PDF was fairly complicated — and expensive, the software to read it was simple. In 2000 this software began to be given away free and in 2008 all the software became an open standard.
