Ubuntu 10.04 Alpha 2 vs. Early Fedora 13 Benchmarks 157

Given that early benchmarks of the Lucid Lynx were less than encouraging, Phoronix decided to take the latest alpha out for a spin and has set it side-by-side with an early look at Fedora 13. "Overall, there are both positive and negative performance changes for Ubuntu 10.04 LTS Alpha 2 in relation to Ubuntu 9.10. Most of the negative regressions are attributed to the EXT4 file-system losing some of its performance charm. With using a pre-alpha snapshot of Fedora 13 and the benchmark results just being provided for reference purposes, we will hold off on looking into greater detail at this next Red Hat Linux update until it matures."

13-Year-Old Trades iPod For a Walkman For a Week 354

BBC Magazine convinced 13-year-old Scott Campbell to trade in his iPod for a Walkman for a week and see what he thought. Scott thinks the iPod wins when it comes to sound quality, color, weight, and the shuffle feature. The Walkman, however, offers two headphone sockets, making it much easier to listen to music with a friend. My favorite part of the review is, "It took me three days to figure out that there was another side to the tape. That was not the only naive mistake that I made; I mistook the metal/normal switch on the Walkman for a genre-specific equalizer, but later I discovered that it was in fact used to switch between two different types of cassette."

Firefox Faster In Wine Than Native 493

An anonymous reader writes "Tuxradar did some benchmarks comparing Firefox's Windows and Linux JavaScript performance. 'We did some simple JavaScript benchmarks of Firefox 3.0 using Windows and Linux to see how it performed across the platforms — and the results are pretty bleak for Linux.' Later on, they tried Wine. 'The end result: Firefox from Mozilla or from Fedora has almost nil speed difference, and Firefox running on Wine is faster than native Firefox.'"

I totally agree with you on that. My point is that you should not throw out fundamental stuff like computational complexity in favor of topics that directly apply to "real-world problems". I think the challenge is to find a good mixture including enough of both types.

The world doesn't need more people arguing over P=NP;

I would argue that the world needs more people (software engineers) that at least understand what the problem of P=NP is all about. Good software engineers know (and care) about the computational complexity of the stuff that they are producing.
