I'm a EVE server dev and this analysis is not quite right. The DB is indeed a central point of failure, but it's rarely a performance bottleneck nowadays. The part about migrating resources is half-wrong, as yes, we can't (yet) move solarsystems around machines without disconnecting the players in it, but unless there's a fight going on in a to be moved system, we still do it to free cpu for the system where a fight is indeed going on.

The Rootkit Arsenal 79

Nicola Hahn writes "One of the first things I noticed while flipping through this hefty book is the sheer number of topics covered. Perhaps this is a necessity. As the author puts it, rootkits lie "at the intersection of several related disciplines: computer security, forensics, reverse-engineering, system internals, and device drivers." Upon closer inspection, it becomes clear that great pains have been taken to cover each subject in sufficient depth and to present ideas in a manner that's both articulate and well organized. This accounts for the book's girth; it weighs in at roughly 900 pages." Keep reading for the rest of Nicola's review.

Strings Link the Ultra-Cold With the Super-Hot 236

gabrlknght writes "Superstring theory claims the power to explain the universe, but critics say it can't be tested by experiment. Lately, though, string math has helped explain a couple of surprising experiments creating 'perfect liquids' at cosmic extremes of hot and cold. 'Both systems can be described as something like a shadow world sitting in a higher dimension. Strongly coupled particles are linked by ripples traveling through the extra dimension, says Steinberg, of Brookhaven. String math describing such ripples stems from an idea called the holographic principle, used by string theorists to describe certain kinds of black holes. A black hole's entropy depends on its surface area — as though all the information in its three-dimensional interior is stored on its two-dimensional surface. (The 'holographic' label is an allusion to ordinary holograms, where 3-D images are coated on a 2-D surface, like an emblem on a credit card.) The holographic principle has value because in some cases the math for a complex 3-D system (neglecting time) can be too hard to solve, but the equivalent 4-D math provides simpler equations to describe the same phenomena.'"

If you're not careful, you're going to catch something.
