Nutrition advice: The vitamin D-lemma [Amy Maxmen/Nature]. “The difficulty of distilling strong advice from weak evidence.” This is a key challenge for researchers/statisticians/data scientists in any domain, not just in health.

Will Amazon offer analytics as a service? [Quentin Hardy/Bits]. Interesting to get an idea what that might look like. I don’t think, though, this would compete with SAS and similar software as the post implies. Would someone looking to implement a product recommendation engine implement it in SAS? Probably not. For example, Google is said to use R for model exploration and prototyping, then puts them into production using Python or C++. I feel a “choosing your analytics tool” post coming on.

Community college budget cuts drive students to for-profit school [Chris Kirkham/Huffington Post]. Balanced coverage of why students turn to for-profit schools and the pros and cons of such choices. My observation: community college tuition is artificially low due to government subsidization while for-profit tuition is artificially high, again because of government interference (in the form of financial aid). No market forces to bring about a reasonable balance between supply and demand. The big losers are students (and taxpayers).

Benchprep is codecademy for any subject, high school to med school [Josh Constine/TechCrunch]. “Eventually, publishers might get a clue that interactive digital education is going to destroy their paper book business. If they’re smart they’ll start developing their own courses or raise licensing fees. Until then though, BenchPrep will be the savior of anyone frustrated by the static book-learning experience.” I’m pretty certain some big textbook publishers see that already.

Forget dieting, try intermittent fasting [Josh Ozersky/Time Ideas]. “And that’s why instead of eating healthier, I’m going for longer stretches without eating so I can actually enjoy a whole meal. I don’t starve myself; I drink a protein shake if I get hungry and consume endless glasses of diet iced tea. People tell me this is bad, that I will soon gain back all the weight I’ve lost – and these rejoinders are always given with a smug malice, as if the people uttering them actually despise me for trying to compensate for the pleasures of the plate.”

I fast most days at work until about 2 or 3 pm, then have a small snack. I eat whatever I want once I get home from work around 5 pm. I find this allows me to eat generally what I want while maintaining my weight at a level I’m happy with. I have found, like Josh, that people get really upset about this plan, almost offended that I would eat this way. Funny how everyone thinks they know what is healthy and what is not, despite the difficulties in determining that (see first link in this post).
