Data centers, open research, Jeopardy!, and tombstones
- Google Server and Data Center Details — Greg Linden reports on a Efficient Data Center Summit. Google uses single volt power and on-board uninterruptible power supply to raise efficiency at the motherboard from the norm of 65-85% to 99.99%. There is a picture of the board on slide 17. (and this is a 2005 board). Greg has left Microsoft as Live Labs is dissolved.
- The Economics of Open Access Publishing — set of papers on the free distribution of research. Pointed to by the RePEc blog. RePEc is Research Papers in Economics, a collaborative effort of hundreds of volunteers in 67 countries to enhance the dissemination of research in economics. The heart of the project is a decentralized database of working papers, journal articles and software components. All RePEc material is freely available. (via Paul Reynolds)
- Computer Program to Take On Jeopardy! (NY Times) — move over Turing Test, IBM’s working on the Trebek Test: a computer program to compete against human “Jeopardy!” contestants. If the program beats the humans, the field of artificial intelligence will have made a leap forward. Really? The system must be able to deal with analogies, puns, double entendres and relationships like size and location, all at lightning speed. Oh, ok. So it’s more complex than inverting the hash table of questions and answers. (via ericries on Twitter)
- The Value of Minimal Data (Powerhouse Museum) — if you have the ability for passionate users to contribute their knowledge, they can turn “minimal” data into a delicious four course data feast with a vintage port to sip during the dessert course. (via sebchan on Twitter)
