The compression is basic run-length encoding, leveraging the Perl repetition operator (x), and the property of the Perl print/say functions that they concat items passed in a list …

Probably the best citation is a remarkable, rigorous paper by Chetty et al (2014) that uses individual IRS returns [1]. To quote those authors: “We find that children entering the …

Internet service is a much higher margin business than television. I don’t see why Big Cable should want to stay in it, at this rate. 81% of the money TWC takes in video subscripti…

The portrait of the college grad painted in the article is consistent with what I’ve seen as an undergrad at Harvard in econ and CS circles. > [College students want money, structu…

Well said. To take things one step further, I’d suggest the main failure may be the claim that we desire to learn languages in the first place, when we’re not willing to integrate …

The traditional American Spanish classroom is probably at least 80% English, and students are in it perhaps 5 hours a week. = 1 hr/week total Compare this with the experience of a …

Yes. As I mention above, I find motivation to be extraordinarily important in learning languages of all kinds. Diving in implies you start with some task you’re already motivated b…
