The 7 Habits of Highly Overrated People
I remember having a discussion with a more tenured coworker, with the subject being the impending departure of another coworker. I said, “man, it’s going to be rough when he leaves, considering how much he’s done for us over the last several years.” The person I was talking to replied in a way that perplexed...

The next generation of Instapaper

Four Hours of Concentration
As I've blogged about before, and mentioned again in my previous post, the great mathematician and physicist Henri Poincaré put in two hours of work in the morning and two in the evening. Apparently this is a common pattern. Cal Newport mentions this in his interview with Todd Henry. Now we also know that if

LLVM Intermediate Representation is better than assembly
The crucial part is IR. It's a common language that sits between the high-level program and the low-level backend . IR is used to express high level concepts and is specific enough that any backend can produce a fast machine code.
