That's 500 lines of code per hour. 8 per minute. 10 seconds per line. I'm not sure what to think of it. Can someone really be that productive in producing (mostly) debugged quality code? Or maybe he did a mostly literal translation so that

One can draw a bifurcation diagram with nothing but a pencil and a pocket calculator, trying different values of r and finding the fixed points / orbits. I think it's the coolest thing one can do with high school arithmetics.

Agreed. My former advisor was as good as anyone in that field. He has a very good introduction (... for a grad course in physics) to the dynamo problem (aka.: the solar cycle) at http://solarphysics.livingreviews.org/Articles/lrsp-2005-2/

The magnetic activity doesn't come from the fusion reaction directly. The sun has a differential rotation profile. Some layers rotate faster than others. This stretches the magnetic flux tubes as they pass through these layers, increasing t

Uh, what? Sun spots come from the magnetic flux tubes from the inner layers becoming unstable and rising to the surface, forming loops. If anything, I'd guess that sunspots inhibit the flow. The mixing happens mostly because of the persis

1. I was writing and rewriting a rebuttal, but you're right... There is something cool about achieving self-reference without a name. 2. Really? If you feel like elaborating / providing link, I'd appreciate.

Math envy. Why do hackers focus on it so much? It has only very remote relevance to normal programming. The beautiful idea I see behind the Y combinator is that of formalism. Once you describe something in mathematical terms, magic can happ

Then you could always go for scheme, it's smaller. But it doesn't really matter. You can start with a tutorial, and just work with the core vocabulary, then gradually expand. I've been doing CL almost full-time for a year, and still, every

Greenspun on shorting: It is 1986. You buy yourself an IBM PC. You are using MS/DOS and say "This sucks. It isn't even as good as operating systems from 1960." You're a computer expert so you know that the technology is pathetic. You do so

Can you give a concrete example of something useful that's hard to do in Python but would be so much easier in Lisp? Languages give you a certain amount of expressive power. By stretching the language, you can always reach a bit higher. Pyt

As someone who always uses it from an Internet cafe, I just wish they'd allow only 1 session at all times. Besides, is there really that much benefit to multiple sessions? It's not like there is much state in Gmail.

I conjecture that the more low-level the language, the more premature optimization is necessary. As an example, an assembly language programmer has to make very early decisions about whether to use a WORD (valuing speed), or a long (valuing

There's more to the syntax than just the parenthesis. That you write (let ((x 4)) (print x)) instead of (let x 4 (print x)) is part of it. So is the order of arguments.
