Bigger & Better

Data, data, data -- data everywhere, and some of us still cringe when our databases hit the gigabyte level. Check out this article on some of the biggest databases out there -- and not only are they big, but boy do they ever perform. Meet AT&T's 96 terabyte database that's compressed down to 26.3 terabytes -- it's a real-time transactional database for operational billing. The British Land Registry has a 20 terabyte DB2 database, running on z/OS that's growing by leaps and bounds -- at its peak, it was processing 702 transactions per second. Experian has an Oracle database running on 4 Sun boxes that handle at peak, 887 simultaneous queries -- and that peak can last up to 8 consecutive hours. Boeing has a 4 terabyte Oracle database that handles at peak, 281 transactions per second. The biggest of all however, is the US Defense Department -- they're building an Oracle database to house the medical records of personnel with a capacity of 50 petabytes, to be hosted on HP Superdome servers. Now that's big!

This is a tale of Morgan Stanley's CEO & Chairman Philip J. Purcell, who basically got his friends onto Morgan Stanley's board, then proceeded to run the show, with no critical questions being asked. Screw the shareholders! Color-Blind Drug Research Is Myopic -- the US FDA just approved the heart failure drug, BiDil, specifically for the use by blacks. There is clear evidence that, for whatever reason, blacks to seem respond to the drug, more so than people with different genetic histories. This is a move towards personalized medicine, however, the implications to race in medical research is uncertain -- after all, there is no such thing as race.

Would the real pirates please stand up?

I've posted about this before ... the Somalian pirates are opportunists -- driven by economic necessity, pure criminality and, some desire to seek justice from the nations in the world that's been raping their coastline for years. The Huffington Post has an article on the stealing of fish and the dumping of nuclear waste along the Somalian coastline. Now, the nations of the world have a new source of terror to fight against, and navies are racing to the scene from many nations, including the US, the Europeans and the Chinese. Sometimes, there is no justice in this fucking world.
