The University of Twente issued a press release based on our paper "The Hidden Energy Cost of Web Advertising". It already drew some attention in the Dutch press!

The paper The Hidden Energy Cost of Web Advertising has been updated with the help of co-author A. Pras, and has been published as a CTIT Technical Report. It now includes a comparison of the total energy consumption by web ads and the energy consumption of Dutch households. It turned out the electrical energy used for displaying web ads is enough to power nearly 2000 households! See the website of the paper at the EEMCS print service or the accompanying page on this site for details.

I noticed that some Flash-based advertisements on websites are rather CPU intensive. Since CPUs can be quite energy-hungry, this left me wondering what the energy consumption is caused by all the web advertising, when browsing the web. Thus, I investigated and wrote a paper on the energy consumption of web advertising. See the accompanying page for the abstract and the paper.

I have a Symbian S60-based smartphone. What I didn't know when I bought this, was the strict security of this platform. It's too strict! Read more on the new page "My Symbian gripes".

I've created a document with much more accurate en detailed information on Nokia Share Online v3.0+ and the Atom Publishing Protocol. See the page "Share online server" for details.
