The issue remains unresolved, said Stephen Hsu, a physics professor at the University of Oregon who blogs about the admissions process. “The only way to answer these questions is to force these schools to open their data sets,” he said. “C

By far the biggest cause of failed email delivery we see is due to bad email addresses that were entered in to the system—problems like ‘joe@gmal.com’ or ‘sue@yahooo.com’. I wonder if you could hack up an 80% solution by comparing the sub

I've never been more surprised by downvotes on HN. This is a quote from a beloved movie that expresses (in a lighthearted way) the exact point made in the OP. I'm very disappointed by the result.

While apathy certainly explains many mediocre instructors, I know for a fact that some outstanding scientists desperately want to be good at teaching but just don't have the magic touch. As a mathematician might put it, knowing the material

I don't think it's the opposite—there are many who "can" who can't teach. (I say this based in part on seven years of taking physics courses at Harvard and Caltech. Trust me: some of the most brilliant physicists absolutely suck in the cl

It's interesting to see how few integration tests there are in Basecamp Next. I used to use functional (controller) tests heavily, but in the last year I've switched over to integration tests (plus Capybara) for controllers and views. (I st

N.B. It's "37signals", not "37 Signals". Impressively, the original VentureBeat headline actually gets this right.

I don't have any plans to make this part of the core tutorial, but it might be a good topic for a future standalone product.

Thanks for the feedback and suggestion. I can understand not wanting to have an announcement hit the HN front page every time a new chapter is released. But even if I don't submit the story, the chances are good that someone else will. By s

It's interesting that this gets highlighted as an example that baffles the 'non-programmers': int a = 10; int b = 20; a = b; This looks obvious to an experienced developer, but it is a clear-cut case of horrible notation. T

If this is 'harping', please keep doing it. Mass assignment/attr_accessible is an important and oft-neglected issue, and I appreciate your taking the time to help. I agree that readers could get the wrong idea by thinking they're better-pro

Teaching good security practices was one goal of the Ruby on Rails Tutorial (a resource mentioned in the OP). It uses attr_accessible for every model and uses find-through-association (emphasizing the security implications of both), and

Bob Palais' original article title, "Pi Is Wrong!", was intentionally provocative. When I suggested the use of tau for 2 pi in The Tau Manifesto , I followed his usage for the sake of continuity. "Pi is wrong!" also makes for a pithier ral

I'm sympathetic to your point; people are so confused about this issue. If a reporter says something offensive on TV and gets fired as a result, it's not a violation of "free speech". In the present case, though, it is a violation of fr

Take advantage of all that extra time. Um, no. Getting up early might minimize distraction, but it doesn't give you extra time. The amount of sleep you need is, to very good approximation, a conserved quantity. And to get up at 4:30 or 5,
