![[Item Permalink]](http://radio.weblogs.com/0112083/images/ur_bullet.gif){kind=small} A career in supercomputing -- Comment()
This week I submitted two new columns to a Finnish IT magazine. One of the columns is written for the web site of the magazine, and the other for the printed version. In the print column I wrote about my experiences in supercomputing. I have spent now over one third of my life working with supercomputers. During this time, the computational capacity had increased approximately by a factor of 1000. (My PowerBook G4 is about as fast as the first machine, a Cray X-MP, with twice the memory.) It is interesting to see if this rate of development will continue for the next dozen years. (As a sidenote, in 1997 I wrote an essay titled 'Working with Information Technology'. This essay discusses my experiences of computational science.)

AAC is hot -- Comment()
Every once in a while I look at the referrals to this site. Most of the referrals are typically generated by Google, or other such search services. Typically there are 150-200 page reads daily, of which over 80% are generated by Google. Today I noticed that really many of the referred Google searches were focused on AAC audio format used in the Apple iTunes Music Store. (AAC is Advanced Audio Coding, a part of the MPEG-4 specification.) I have also apparently mistyped (once again) on my weblog, because also searches containing the term ACC were referred here. (I inserted a correction to the original entry.)
