Google filed a patent for Google Desktop last month, that hints at how they rank search results. Last access time, where the item is stored, file type and file size are mentioned as factors, but there are probably some more left unmentioned.

Google Adwords algorithm

Sat, 24 Sep 2005 12:00:00 +0000

Interesting experiment to test the impact of changing the rate for Google Adwords. Two identical sites have Adwords account. One has an established account paying $0.10 per word. Another is a new account, and begins by paying $1.00, then lowers it to $0.40. The former got 15,000 click-throughs regularly. The latter started just above 15,000 and fell to 1,200 after the rate drop. Does the Adwords algorithm favours rate increases disproportionately (and hence is evil?) Or is the fact that the former site an established one create the difference?

Quantum computing takes steps forward. First, we improve our storage ability with 1000 bits in 1 molecule. Then we perform the Grover algorithm using molecules. Now, all that’s needed is a good set of problems to solve.

Oracle of Google

The Oracle of Google is the coolest Google app so far. Ask it a question with 4 choices, and it uses Google to guess the answer. It knows that Abdul Kalam is India’s President, though it did prefer Vajpayee to former Presidents. via Google Weblog
