Well, rather a fun good evening, and all change...

 From Ubuntu and OS X on PowerPC to:

We also:

took part in a smoking/no-smoking survey;

I mentioned an article on "Intel Developers' Forum Spring 2006: Will 
Intel's Core Architecture Close the Technology Gap?" at Toms Hardware 

Brief discussion about systems-on-chip and monolithic multi-core CPUs 
versus clusters, FSB/memory bottlenecks, cache, parallelism, threads, 
algorithms, programming languages and trends, diminishing returns of 
more than 4 execution units for a single task/thread, threads versus 
state programming, Hurd(!), PVM and others;

Watching soccer at 10am in the morning and America, hi Adrian;

Backups for multi-TBytes of data, hardware vs software RAID, SCSI, IO 
limits, LVM, filesystems, mounts, NFS, SMB, kernel;

Current kernel problems and SLABs;

We also descended into the kernel source to investigate /proc/kcore 
access rights and why the "That's very stupid" comment on the kernel 

...And then suddenly the pub had closed and most of us had to escape out 
via the fire exit!

All good stuff, and a very entertaining video from Martin G! (I 
especially liked the window docking tricks and the video cube effect. 
Good fun.)

And nothing like the originally intended talks. This must be one of the 
best examples of the "Bazaar" method for a presentation as opposed to 
the "Cathedral" method.

And that got mentioned also, and also how well or not kernel development 
followed that model and whether there is also a third arrangement of a 
Cathedral /of/ many Bazaars...


Next meeting/social next Blue Moon Wed (2006/03/30 - ISO date format so 
as not to confuse Adrian ;-) ) Further details nearer the time (JIT!)

Cheers all,
