This is a really impressive demo. Most virtual globes (e.g. Google Earth) separate the terrain, surface image and building data. Normally, these are sent to the client separately and merged in the graphics card: the surface image is textur

Do the back-of-the-envelope calculation on antimatter. I did it once, then mislaid the results. First question: make it or farm it? If you want to create antimatter then, at the very best, energy in = energy out. The energy required to ac

Tom Anderson gets it the wrong way round, and completely misses Siegler's point. The question is not is why does Siegler care. He can reasonably expect to care: it's his photo attached to his personal profile and his photo is part of how he

Quick math. We don't see the tube, but assume that it is 1m long. The experimenter picks drops the 100g magnet into the tube once per second and that it has zero velocity at the tube exit. i.e. initial and final kinetic energy is zero, but

Sorry, I should have explained. Scala feels very much like "Java done right". Scala solves a lot of problems with Java and is better in every respect. In the same way, Subversion solved a lot of problems with CVS and is very much "CVS done

Having dipped my toes in Scala, and written some Clojure, it seems to me: If Java is CVS, then Scala is Subversion and Clojure is git.

SQL is fantastic, but the annoying bit is that you have to create strings to send to the database, and generating these strings correctly is hard. One of the key features of libraries like Korma and SQLAlchemy is that they provide a very e

It's really simple: read the syllabus. The syllabus tells you so many things: - what the lecturer considers fundamental; - what is optional; - what you will be asked about in the exam. The syllabus is better than any revision notes. At the

You're asking the wrong question :) It's not about what specific questions you should ask. The question you should ask yourself is "what am I looking for and how to I detect this?" Only you can answer the first part, the second part follow

I'm a computer geek. That's it. I usually get a short, puzzelled stare, followed either by either a "what, exactly?" if they wanna talk about it or a "oh, change of subject..." if they don't. However they answer, go with the flow. BTW, I'm
