Another thing I never thought off

A while ago a made a post on web standards saving money (ie for google). Today I was listening to another podcast, they had an interview with Chris Dibona He works over at google. He was talking about how google has its own team of kernel hackers. He explained how some small improvements in the linux kernel of this team could save google millions of dollars.
My first reaction was offcourse, your site will run faster you need a couple of computers less and that’s where your savings come from. Well he explained it somewhat different. Let’s say you have 100.000 computers (prolly google has much much more), your computers will stay a little bit cooler maybe even consume less power. So your airco could run a little bit slower. So a code optimization could result in a cut back in power usage. You would maybe even save some trees!

It shows how in each and every sector of the it you have to worry about different things. I have to admit, when I’m doing java development and I’m not sure if I should choose an int or a long, I’ll be choosing a long because memory is no problem for us and it’s only running on 2 or 3 severs. These guys will check,recheck and then check again if they instead of the int maybe even could use a smaller datatype.
