- Intel has decided to shut down its lablets in Seattle, Pittsburgh and Berkeley! This is old news apparently, but I just learnt of it.
- I have been a lot of thinking about the best model for workspaces. Some of the models individual offices, cubicles, and clusters of desks. At WINLAB, we had low-walled cubes. Richard Hamming famously stressed on the importance of having one's office-door open if working in a research lab with individual offices. Here is a nice post on the subject from Matt Welsh who recently moved from being a professor at Harvard to working at Google. At the AT&T security research group where I work, we use a open collaborative workspace with clusters of desks and I can see that it is more productive than the cubicles at my erstwhile grad school lab.

I suspect one of the problems in the health care system in America is information asymmetry. The moment a customer hands over an insurance ID to a doctor or hospital, the clinic knows a significant amount of information about the patient. The clinic knows the patients health history, financial situation and the type of insurance plan he has. The average patient knows almost nothing about the internal working of the hospital. Try to think about how many bits of information the clinic possess about the patient, and how many bits the patient possess about the clinic. From a purely rational point of view, it may be in the best interest of the clinic to overcharge the patient for services he doesn't really need, knowing that his insurance will cover it. Even if the clinic gets caught doing this once in a while, the odds of getting caught may be low enough that the clinic may decide to pursue such a policy in the long run.One simple change that can be made is: do not provide insurance information about individual patients to the healthcare provider. This can be done by placing a government body as a liaison between the health care provide and the insurance companies. In this model, the hospital submit the bill to the government body and this body follows up with the insurance company. The hospital/clinic and the insurance company never interact directly. Another way to disincentivize misbehavior on the part of clinics might be to create a public, review-supported, ratings service, ala Yelp, for medical clinics and individual doctors. The problem with this is potential for false reviews and sybil attacks, which makes me wonder why apartmentratings.com seems to have so many fake reviews, while yelp seems relatively cleaner.Update: A large amount of medical records data has just been released by the Heritage Health Prize via Kaggle. While the intended purpose of this data is to host a competition to predict which patients are admitted to a hospital within 1 year of the time frame of the data, I wonder whether it could be used for other interesting investigations and verification of theories, such as the one above.
"Whenever I start working on a new problem, I never look a the literature in the area first.. that baises the mind. I try to attack the problem myself and then see the literature, only to discover that half of what I worked out has already been published. But that's okay, there is still the other half!" - Godfried Toussaint at colloqium lecture at NYU.
