"Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful." (George E.P. Box and Norman R. Draper, Empirical Model-Building and Response Surfaces (1987), p. 74)

"One of the most insidious and nefarious properties of scientific models is their tendency to take over, and sometimes supplant, reality." (Erwin Chargaff)

I think that says it all, really.

Comment: The Celine Dion effect (Score 1) 89

by Bud (#36328902) Attached to: AC/DC Music Attracts Great White Sharks

One wonders if they'll be turned off by Celine Dion music — a new type of shark repellent perhaps?

Oh yes, the "Celine Dion effect" is well known. For example, playing My Heart Will Go On in railway stations late at night will magically keep the stations empty from pickpockets, rapists and other miscreants and indeed any sentient beings except cockroaches. The high notes will first melt your earwax and then your brain. Cockroaches merely lose their orientation and walk into walls.

I don't see any reason why it wouldn't work underwater too. Unless of course the sharks fight back with lasers.

One element I pushed was that nobody was going to be interested in their kernel, regardless of what they did, and that conversion to Linux would eventually be necessary if they were not to continue to expend millions on re-inventing the wheel.

Not a good thing to push because the kernel is the interesting part of Symbian. It's power-tight and has real-time features, both of which are very nice features in a mobile communications device. Unfortunately it only runs on ARM. Linux on the other hand runs on everything. With Qt on top of both Symbian and MeeGo, there's nowhere Nokia can't go. (There's no guarantee they'll actually go there, but they *could*.)

Ouch - this is the best that Hubble can do? The images show serious chromatic aberrations, with significant red-blue fringing on edges. What's worse is that the effect gets more pronounced as the camera moves around.

Given that the camera moves at relativistic speeds, the chromic aberrations are probably a relativistic effect and would of course get more pronounced the faster the camera moves. Another interesting side effect is that while for you the movie is over in a matter of minutes, someone observing you will feel that the movie takes too long, and incidentally also perceive you as significantly smaller.

Kids, don't try this at home!

Red Hat, Novell issue back-to-back announcements->

Submitted by Anonymous Coward
An anonymous reader writes "In the past 24 hours, the Red Hat Enterprise Linux (RHEL) beta became available through Amazon's Elastic Compute Cloud (EC2) service. While RHEL has been available in limited beta for a few weeks, this public beta announcement came on the heels of Novell's launch of SUSE Linux Enterprise Real Time 10, its latest enterprise OS offering. The launch of SUSE Linux Enterprise Real Time 10 is arguably the bigger announcement. Novell's new SUSE is a real time operating system, allowing critical processes to take priority over processor tasks."

SPAM: Which certifications are worth your time?

Submitted by alphadogg
alphadogg writes "For years, the key to jumpstarting a network professional's career was getting a Cisco, Microsoft or other technical certification. But now CIOs, IT recruiters and salary specialists say demand is waning for hardware- and software-oriented certifications. Instead, companies are looking for IT professionals with business-oriented certifications in such areas as project management and Six Sigma, a statistical quality improvement technique that is being adopted by more IT shops."

Three-Way Music Software Shootout ->

Submitted by
ThinSkin
ThinSkin writes "Squabbling with bandmates is an old and busted tradition for rock stars. With games like "Rock Star" and "Guitar Hero," gamers are turning to media to unleash their inner rock star. Musicians a little more serious about crafting music can turn to computer apps to translate ideas into songs. Joel Durham Jr. over at ExtremeTech has a review of three popular music creation programs: Cakewalk SONAR Home Studio 6 XL, Sony ACID Music Studio 7.0, and MAGIX Music Maker 12 Deluxe. Each program has enough versatility for users to begin making music, but the right program depends on a person's skill level and budget."
