Filtering the Internet

During the last year there have been several discussions about filtering content on the internet. Should this be dealt with by the government (creating better legislation) or should ISPs come with a solution?

Last week the WODC (Research and Documentation Centre) published an interesting report (Dutch with English summary) about the technical and legal possibilities of blocking and filtering child pornographic material on the internet. In their research the WODC tried to find an answer to the question: what are the technical posibilities of filtering and blocking content on the internet and what are the legal possibilities?

EU gets involved

I just read a press release from EU commisioner Viviane Reading about energy savings in the IT industry. I found the interesting part of the press release that the commission is also recognizing that the IT industry is not only a consumer of energy but also a source of many energy savings for many other industries. This is often overlooked in the argument about datacenters. The commission refers to the energy distribution industry, the cooling/heating of buildings, and lighting. The press release is vague about how the commission will stimulate this process but at least the technocrats are thinking about the issues.

Power supply units

We spent a lot of time on energy efficiency and it might be interesting to share our experiences with the community in order to exchange best practices.

It is very important to really think through your choice of hardware. In particular the energy loss of a power supply unit of a server is concerning. Google claims in a white paper that you are likely to loose 30 – 40% of power in a typical power supply unit. The reason is that the power supply unit converts AC to DC power which results in heat (ie loss of energy). Google however has developed servers which loose only 10% of the power.

Choosing hardware with efficient power supply units is obviously of paramount importance. But where do you find these efficient power supplies ? The answer is simple: you cannot. Humans have built nuclear reactors and sent people to the moon but efficient power supply units are still not around except for the likes of Google. Read the rest of this entry »
