Data Mining Applications usually have databases with hundreds/thousands columns. Imagine that you need to derive a rule based on as much input variables as possible. Is very easy to generate many columns, for example take a Telco Churn Model, you will have for each phone number, # of calls on the last month, # of calls on the month before, etc, then same for call duration, max, min, ratios between months, you name it, if you are using for example just 20 vars and one year history, you can have 240 raw vars. Then you have ratios between them, if you take 4 months ratios you have 6 new vars for each original var, add 72, and so on.
Never seen more than 5 thousand columns because of technical limitations, but I'm sure that if you give a DM Expert the possibility to have 2 billion columns they will fill them all.

The Proton Just Got Smaller 289

inflame writes "A new paper published in Nature has said that the proton may be smaller than we previously thought. The article states 'The difference is so infinitesimal that it might defy belief that anyone, even physicists, would care. But the new measurements could mean that there is a gap in existing theories of quantum mechanics. "It's a very serious discrepancy," says Ingo Sick, a physicist at the University of Basel in Switzerland, who has tried to reconcile the finding with four decades of previous measurements. "There is really something seriously wrong someplace."' Would this indicate new physics if proven?"

We have MySQL vs. Oracle DB, Netbeans vs. jdev, but also JRockit (ex BEA) vs. SunJVM.
I don't see any good loosing one of SunJVM major competitors.

AACS Device Key Found 351

henrypijames writes "The intense effort by the fair-use community to circumvent AACS (the content protection protocol of HD DVD and Blu-Ray) has produced yet another stunning result: The AACS Device Key of the WinDVD 8 has been found, allowing any movie playable by it to be decrypted. This new discovery by ATARI Vampire of the Doom9 forum is based on the previous research of two other forum members, muslix64 (who found a way to locate the Title Keys of single movies) and arnezami (who extracted the Processing Key of an unspecified software player). AACS certainly seems to be falling apart bit for bit every day now."
