Melbourne school uses KDE and Kubuntu for library kiosks

Westall Secondary School in Clayton South, Melbourne, has started using KDE under KUbuntu Linux to allow them to replace the 3.0GHz Intel PC’s they were using with older 2.1GHz PC’s, extending their lives and avoiding landfill. The systems use KDE’s Kiosk framework to let the staff lock down the systems for their library system. The 3.0GHz machines released from this role will be going back into the main school for teaching duties there.

In explaining why the school went for Kubuntu, Stefyn said the students responded well to CDs put out by the Ubuntu project. Many had tried Ubuntu at home, which led to a decision to provide a familiar working environment at the school as well.

They got help both directly from Peter Lieverdink and also from the Linux Users of Victoria. They are also encouraging students to experiment with Linux, with old PC’s as a prize:

During our last hardware cleanout, we challenged the students to create the best Linux install and customization, and the winners would get to keep the hardware once it was decommissioned.

and all that apparently unnecessary desktop bling helps to get attention, according to the schools IT manager and teacher:

The kids were rapt with Compiz Fusion and this scored magic brownie points, because even the magical Vista couldn’t compete with the graphics. This was a great step into having them explore the other functionalities of Linux

Great stuff!

Australian “Open Source Industry & Community Report” published

So Jeff Waugh has announced the “Australian Open Source Industry & Community Report” has been published as a PDF (( or you can buy a hardcopy version )), hopefully the first of many.

Come and see what Open Source really does for Australia!

Our conservative projection of earnings suggests that the Open Source industry generates $500 million in revenue each year, with over 50% of that being directly related to Open Source.

The report is covered by a CC license:

btrfs 0.13 and XFS benchmarks

Back in February Chris Mason announced btrfs 0.13, so I thought I’d give it a quick go as I’d not touched it since testing btrfs 0.5 back in August. Back then, on some pretty meaty hardware, there was a considerable difference between XFS and btrfs and I was curious as to how they’d compare now.

The test hardware this time is a quad core Intel box with 8GB RAM and a pair of 750GB SATA drives in a RAID-1 mirror. It is running Kubuntu Hardy Heron (now in beta) with a 2.6.25-rc6 kernel.

A quick blast with Bonnie++ surprised me, btrfs matched XFS for read, writes and rewrites (though with higher CPU usage, presumably due to the fact that it’s checksuming all the data) and then blew XFS away for meta-data operations.

Operation XFS btrfs
Block write (KB/s) 50572 42087
Block rewrite (KB/s) 23739 23296
Block read (KB/s) 52512 53108

LCA 2008 Day 4 Photos

I have uploaded my photos from Thursday (Day 4) of Linux.Conf.Au 2008 at Melbourne University. They are exclusively of the RepRap that was being shown off today and a gathering of people experimenting with the wireless mesh and collaborative capabilities of the OLPC XO’s that were distributed yesterday. I’ve already heard of at least 2 bugs being found through this release of machines to developers (one by Jason White).

I’ve just rearranged & geocoded all my LCA 2008 photos on Flickr into a set per day, gathered together into a single collection, which makes life easier for people who just want to see what happened on what day! I’ve updated the links on previous blog entries to point to the right set for the day in question too.

LCA 2008 Speakers Dinner and Day 3 Photos

I’ve now uploaded more photos onto Flickr from the speakers dinner on Tuesday night held at St Pauls Chapter House (near the cathedral), built in 1891, a lovely building! I don’t have any photos from the day on Tuesday as I had to work.

There are also photos from Day 3 (Wednesday) where at morning coffee there were LWN cakes to celebrate LWN’s 10th birthday and we were distributing OLPC XO laptops to various chosen delegates for them to go develop amazing things with (or give them to someone else who would). It was a great buzz to make peoples day like this, especially when they tell you what they could do with them!
