Søren C's blog

Jeg har været til Fredags Rock i Tivoli de sidste par fredage. Dette blogindlæg skal dog ikke handle om hvor god / dårlig musikken var… nej, dette indlæg skal se fremad!

Jeg har årskort og regner med at besøge Fredagsrock rigtig mange gange i år. Men jeg er altså ikke gode venner med Tivolis hjemmeside, specielt ikke at finde frem til deres Fredagsrock kalender (den kan dog findes her).

Så jeg har sat mig ned (nej, jeg havde ikke noget bedre at tage mig til i dag…) og skrevet alle dem der spiller ind i min elektroniske kalender.

Long story short, her er iCal filen (.ics) for Fredags Rock 2007, det kan jo være at andre også vil finde den nyttig:

Tivoli2007.ics

Så er det lidt lettere at planlægge sine kommende fredage så man når at høre Rasmus Nøhr, men slipper for at befinde sig i Tivoli når Niklas og Jannik spiller (eller omvendt, hvad ens musiksmag nu dikterer).

Ubuntu 7.04 released

My torrents are already running and this evening I’m going to a Feisty release party. Since I have been running Feisty since February 25 the official release doesn’t really mean anything special for me, but it is alway nice to celebrate in some way.

Congratulations (and thank you) to all the developers etc.!

I have been playing around with BOINC the last couple of days. It took me some time to figure out a couple of things though.

My laptop runs 64 bit which can be a problem with some of the projects using Boinc. Einstein@Home (as well as many other projects) doesn’t support 64 bit. So with a standard install I would get error messages looking like this one:

Message from server: platform 'x86_64-pc-linux-gnu' not found

There is (as always) a fix – this should work in general, but I have for obvious reasons only tried it on my own Ubuntu laptop. First you need to be able to run 32 bit applications. This is done by installing ia32 libraries:

sudo aptitude install ia32-libs

Then you have to tell the Boinc client to request work as if it was a 32 bit pc. This is done by shutting down the boinc client

sudo /etc/init.d/boinc-client stop

and then, in the file /var/lib/boinc-client/client_state.xml replacing the line

<platform_name>x86_64-pc-linux-gnu</platform_name>

with this one:

<platform_name>i686-pc-linux-gnu</platform_name>

and start the Boinc client again

sudo /etc/init.d/boinc-client start

Another option is to put your 64 bit processor to use and work on some of the projects that actually support 64 bit…
Here is a list of projects supposed to have native 64 bit applications (I have only tried ABC@home my self):

• ABC@home
• Chess960@home
• Predictor@home
• SIMAP

Of course the two options above does kind of exclude each other. I have not found a way to report one platform to some projects and another platform to others. It would seem nice with a ‘fallback’ platform to be reported if the x86_64 fails, but maybe that will come in the future. On the other hand it seems like a good idea to use only optimized applications on 64 bit hardware. The last approach is the one I’m using currently.
You can see my progress here:

Det havde jeg sgu styr på!
– eksamen altså, og min karakter afspejlede det også!

Så nu er jeg super glad, har en uge fri og solen skinder fra en skyfri himmel. Super!
