Rosetta 3.2 with Ubuntu 11.04

Wed, 11/05/2011 - 10:45 -- Morgan

Rosetta is a very useful program for the prediction of protein structure, folding and interactions be that docking with proteins or ligands.

However, the current version of Rosetta (3.2.1) uses SCons to compile itself on your system. This is usually fine except that these use gcc libraries 4.1 and before.

Ubunutu 11.04 considers anything before gcc v4.4 to be obsolete and you can't install them (even with apt-get).

As a result, a small amount of hacking is required.

First get SCons. Open a new terminal window.

Recovering a RAID1 disk from a corrupt array

Tue, 12/04/2011 - 15:38 -- Morgan

I recently had our backup server at work die. Upon investigation the Kubuntu 8 server had had it's OS drive and one of the RAID1 data disks corrupted to such an extent it couldn't boot. The bad data disk was so bad that it couldn't even be assigned a hardware address under Linux or Windows.

The only hope remained with the remaining RAID1 disk.

As the server had been set up by a previous administrator as a software RAID, I thought it would be a nice simple job of sticking the drive into a good computer and copying files off.

Alas no.

Real or Fake: Sennheiser IE 7 s

Tue, 28/12/2010 - 21:09 -- Morgan

When you have a certain taste in music, you develop quite an ear for it. And at that point you find yourself hating poor quality equipment, which inevitably means you're doomed for the rest of your life in spending quite a lot of money.

As a result of my Shure earphones going walkabout, it was time for a replacement and after doing my research and a sound test, I settled upon the Sennheiser IE 7s. Not really being able to afford the IE 8s and having asked a few people in the know they said the difference was so negligible it didnt justify the price difference.
