Slashdot Redux

I recently picked this up from Slashdot. A British scientist became the first human to be infected by a computer virus! :) Yes – you heard that right – a computer virus. Read the full story here.

Apparently he infected a chip implanted in his body and then caused the virus to spread from his body to his PC! And he argues that human-to-human computer virus infections will also become common as implanted chips become commonplace!

Among other techie news, Sony recently demoed a flexible OLED screen thinner than a human hair! And it is flexible enough that it can wrap around a pencil even as the video keeps playing!! How cool is that. :)

And on top of all this, a research group in the University of New South Wales has successfully created a 4nm transistor made of just seven atoms! Just seven frikkin atoms!

Very cool stuff!

Euler Visits Silicon Valley

Here’s an Euler tour of the Bay Area! Of course many more such tours are possible. The one I have here is 165 miles long and it will take an estimated four hours to drive around the loop. It should be a fabulous day out for a photographer!

For those not well-versed in Computer Science, an Euler Tour is a path through a graph that traverses each edge exactly once. In this particular case, bridges are the obvious edges. Nodes aren’t completely clear though since the land masses are amorphous and not clearly demarcated from each other. For my purposes, I assumed there are three distinct nodes corresponding to WestOfBay (SF, SouthBay, Peninsula etc), OverTheBay (Marin, Sausolito etc) and EastOfBay (Walnut Creek, Fremont etc).

Can you come up with a shorter Euler Tour which covers all the Bay Area bridges? One condition your tour must obey is that the stops in the tour must be city centers and not arbitrary points on the map. For example, in the tour that I display here goes as follows: Redwood City -> Hayward -> San Francisco -> Sausolito -> Rollingwood -> Vallejo -> Walnut Creek -> Fremont -> Redwood City.

Well done, Vishy Anand

A wonderful write-up about a man I immensely admired in my childhood (and still do).

At some time in the past, I used to be pretty good as a chess player (compared to other players my age). Somehow, over the years, my skills stagnated. However, Anand’s successful defense of his World Champion title has sparked a new desire to become good at chess again :)

Not sure how many people read these posts, but it would be awesome if I could find a group of three-four people who want to get better at chess and are roughly at the same skill level as myself.
