Our field is founded on the idea that mechanical computation is preferred to human computation.

There are two competing definitions of Turing complete here. 1. The mathematical definition of Turing completeness: models which can simulate the computation of a hypothetical Turing machine. Idealized circuits are an example of this. Turin

In 2010 I wanted an iPhone Twitter client with a nice UI and no ads, so I paid $2.99 for Tweetie 2. This was after I bought Tweetie 1 for $2.99. Tweetie 2 wasn't a free upgrade. In 2011, after acquiring Tweetie 2 and making it free, Twitte

It's a bad idea to use mirroring and rotation when creating glyphs. The reason is that it ties the correct interpretation of a string to its position and orientation in space. Generally we want meaning to be absolute. The meaning of a strin

An excellent article. Full of things I haven't seen. I will second his recommendation to read original works. They aren't always the best, but in many instances they can teach you a lot more than just the topic at hand. If you have your gra

I've not been in the paper myself, but many of my friends have, and the first thing they always point out is how badly the paper misquoted them. I always expected the things I read in quotation marks to be quotations, and it was surprising

It's best to keep things in-memory if you can. Since you mention MySQL I assume that's what you're using to persist data. Storing a tree in a flat database is kind of a challenge. This page ( http://www.sitepoint.com/article/hierarchical-da

A downarrow doesn't have to work in the exact opposite way as the uparrow. In the trivial case the downarrow would do nothing, and then site wouldn't change at all, except cosmetically. In the more generalized case you would: -weight it ver

Thanks to the author for taking the time to write this up. We recently had to buy a digital certificate ($99), and it felt very much like a digital mugging. In a year it reverts to $499. You can get a nearly identical SSL certificate for le

'/' in this case is the adverb 'over'. When applied to a function it causes that function to fold over a list. This is the same as inject as far as I know. You are correct in supposing that !n generates an array of integers from 0 to n-1. I

The idea is genius, the act itself, when it isn't explained to the consumer, is completely immoral. I'm reminded of the "Your Family's Geneaology Book", where "Your Family" is replaced with your last name. For instance, "The Smith's Geneaol

Corporations won't benefit from gambling on more expensive programmers. They've already created a structure that takes in programmers, anyone with even a basic proficiency, and ensures that they produce at some specified minimum. It's a sys

Eval in Lisp is half a page. That's not a lot of material. If you further discount machine language, the only thing left for a compiler/interpreter to do is handle eccentricities in language syntax. This is rote and arbitrary application of

This is a very long article, and it's founded on a false premise. Compilers is not an important topic because there's nothing universal you can take out of it. Machine code as we know it is a pretty arbitrary construction. Register machines

Three non-collinear points determine a plane. A counterexample to your proof would be to draw a plane through three points, say near the top of the sphere, then distribute the remaining points on the bottom. Then you don't get a proper divi

This is shorter than both the Ruby and the Arc versions: {x set y+eval x} It's in q, a verbose version of a language called k. Applying it to a symbol/variable `n will give you a functional projection you can apply to any i.
