Twitter Analyzed

Tuesday, June 30th, 2009

This is the main reason I’ve never seen the point of joining twitter. There’s no content there that I’m interested in. That is, until the Iranian protests. But even then it was difficult to find what I was looking for.

the top 10% of prolific Twitter users accounted for over 90% of tweets. On a typical online social network, the top 10% of users account for 30% of all production. To put Twitter in perspective, consider an unlikely analogue – Wikipedia. There, the top 15% of the most prolific editors account for 90% of Wikipedia’s edits ii. In other words, the pattern of contributions on Twitter is more concentrated among the few top users than is the case on Wikipedia, even though Wikipedia is clearly not a communications tool. This implies that Twitter’s resembles more of a one-way, one-to-many publishing service more than a two-way, peer-to-peer communication network.

NYT: Datacenters

Thursday, June 11th, 2009

Interesting NYT magazine article about datacenters and the infrastructure that runs the internet.

Tukwila is less a building than a machine for computing. “You look at a typical building,” Manos explained, “and the mechanical and electrical infrastructure is probably below 10 percent of the upfront costs. Whereas here it’s 82 percent of the costs.” Little thought is given to exterior appearances; even the word “architecture” in the context of a data center can be confusing: it could refer to the building, the network or the software running on the servers.

I like guitarists that take saxophone as their inspiration. Here’s Fredrik Thordendal from Meshuggah doing a short demo.
