OLS topics on the last day including Extreme High Performance Computing, the Linux Desktop Audio Mess and IOMMU Performance
OLS topics on day three including Lguest, SMB2, Large memory allocations and Concurrent Pagecache.
OLS topics on day two including Linux Kernel Development, EXT4, Cell Broadband Engine, Debugging Google clusters and LinuxBIOS.
All the OLS papers have now been posted. The talks were recorded this year, and the videos may be released online for free once the cost of production is covered by purchased copies. Contact Andrew Hutton if you can help by purchasing a copy.
The ninth annual OLS has begun in Ottawa's sweltering summer heat.
There are as many as three different talks and two different tutorial topics being presented in each time slot. This is a summary of the talks I attended in day 1.
Django comes with an amazingly powerful database API that does a very good job of hiding database-specific SQL. Sometimes, though, the API doesn't do exactly what you expect. I ran into this when developing the code that displays the “Tags” that have stories posted.
Fortunately, there is a fairly easy way to get down to the SQL and see what is happening when something goes wrong.

This is a maintenance release that fixes a number of bugs that have been found in 0.9.8.
OLS is just days away, and once again the schedule is hard to read and even harder to print.
Here is my attempt at re-formatting the schedule to make it easier to use. Please note this is not the official schedule. You can find the official OLS schedule here.

On May 31 I gave a tutorial on the new site code for the Ottawa Canada Linux Users Group.
The new site is based on Django. It implements the logic for displaying upcoming and past events, tracking speakers, locations and images. It can also display announcements as part of the front page.
The slides from my tutorial and the source code at various stages are attached below.
I know some people will disagree, but I greatly appreciate the work of Ottawa's National Capital Commission. They may be unelected and unaccountable, but thanks to them (and a blocked off and overgrown roadway), I have a ½ hour commute to and from work that is truly idyllic.
UPDATE a new version is available, see: XTerm 256-Colour Chart 2.0
I have written a small utility that can display a chart of the 256 colours supported by XTerm or the 88 colours supported by Rxvt.
Instead of the usual sliced-colour-cube view of the available colours, I decided to “unwrap” the cube. The shape of the chart is irregular for this reason. Unwrapping the cube in this way separates out the neutral colours from the colours on the outside of the cube.
