Hello All, Here is some more information from Greg's note at last Friday's presentation. I'd also like to thank Greg for volunteering to talk and for such a well presented and technical topic. Seeing the data miner in action was also a bonus. Attached is the email that Greg sent to Bruce and myself earlier this week. It seems as though there is plenty more reading on the topic. I've also loaded Greg's presentation to google docs so that those that weren't at the meeting can appreciate the presentation. <quote> Hi Chris, Bruce, as discussed here's the slideshow and talk-notes from last night I promised I'd send to you to forward on to relevant people, (group-wide bounced me on the email size limit).

KDE 4.7.2 bug: entries added via kmenuedit don't show up in menu
by Peter Reutemann 23 Nov '11

23 Nov '11

Hi there Just came across an annoying bug in kmenuedit in 4.7.2, when adding custom launchers. After clicking "Save" the launchers don't show up in the menu. After some digging around I came across the following thread: http://kubuntuforums.net/forums/index.php?topic=3118688.0 A quick fix, thanks to this thread, is to go into the following directory: $HOME/.local/share/applications And remove the following lines from the affected .desktop files: OnlyShowIn= Path[$e]= That will make the entries appear again in the menu (just log out and in again). Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cs.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Tails, the incognito live system
by Peter Reutemann 20 Nov '11

20 Nov '11

If you care about anonymity online, you might want to check out "Tails": Tails, "The Amnesic Incognito Live System", a live CD or USB distribution of Linux which is designed to preserve privacy and anonymity, has been updated to version 0.9. The developers also urge users of the previous version, 0.8.1, to upgrade due to "numerous security holes" in that release. -- H-Online.com article: http://h-online.com/-1381623 -- homepage: http://tails.boum.org/ Cheers Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cs.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Saturday workshop
by Chris O'Halloran 10 Nov '11

10 Nov '11

Hello everyone, Thanks to Ian and Bruce on their presentations last night. Seemed like it was night for presenting on coding. Perhaps Ian will resolve his 64-bit problem :) It seems from the Monday meeting that there is interest in holding another Saturday workshop. Can I have a quick show of virtual hands to those that would be interested for a workshop on November 12th, please? regards, Chris
