Hackers can hack your pacemaker!

Up till now, the worst that computer hackers could do was steal your passwords, and maybe your money from your bank accounts. Now, comes evidence, that it is theoretically possible for a hacker to wirelessly hack into the pacemaker that a is installed in a person’s chest and modify its settings – and actually kill the person.

See this post for:

To the long list of objects vulnerable to attack by computer hackers, add the human heart.

The threat seems largely theoretical. But a team of computer security researchers plans to report Wednesday that it had been able to gain wireless access to a combination heart defibrillator and pacemaker.

They were able to reprogram it to shut down and to deliver jolts of electricity that would potentially be fatal — if the device had been in a person. In this case, the researcher were hacking into a device in a laboratory.

Gives a new meaning to the phrase “he is in the hospital with a virus infection”.

Student families in school

My kids’ school, Vidya Valley, has just introduced something they are calling “Tutor groups” in school. A tutor group is a group of 15 to 20 students consisting of a few students from each class from 5th to 10th standard (aka grade). Each tutor group is assigned one teacher (“Guardian Tutor”) whose job it is to ensure the full welfare of the children in this group. Here, “full welfare” specifically refers to non-academic issues, like mental and physical welfare (for example to help with bullying, truancy issues, or special medical attention).

Each student stays in the same tutor group for all the 5 years, and the guardian tutor of the group remains the same throughout. Each year, the students of Std. 10 will obviously pass out and leave the group. At this time, new students from Std. 5 will enter the group. This whole set-up creates a sort of a family unit, where the guardian tutor becomes the surrogate parent, and the other students become surrogate siblings.

The tutor group meets every day for a little time – the school time-tables have been adjusted to allow for this. In addition, they meet once every two weeks for a longer period. These meetings have no agenda. Just hang out and bond and behave like a family.

See this pdf for a more detailed description of the guardian tutor system in Vidya Valley.

It sounds like a very interesting idea, and I have not really heard of anything like this being used in Pune schools (but I could be mistaken). In any case, seems like a neat thing to have. They have introduced it just a few months ago, so it will be interesting to see how it works out in real life.

Internet for the villages

This is what the internet looks like for a village.

The Question Box is a project from UC Berkeley’s Rose Shuman to bring some of the benefits of the information on the Internet to places that are too remote or poor to sustain a live Internet link. It works by installing a single-button intercom in the village that is linked to a nearby town where there is a computer with a trained, live operator. Questioners press the intercom, describe their query to the operator, who runs it, reads the search results, and discusses them with the questioner (it’s like those “executive assistant” telephone services, but for people who live in very rural places).

The Question Box has been deployed live in Phoolpur village in Greater Noida, close to New Delhi and it was a stonking, smashing success, and will now be expanding further.
