Well, the Colossus wasn't "based on bomba technology", and was never used to crack Engima.
The Mathletes and the Miley Photoshop 555
Frequent Slashdot contributor Bennett Haselton's essay this week is about
"A Tennessee man is arrested for possessing a picture of Miley Cyrus's face superimposed on a nude woman's body. In a survey that I posted on the Web, a majority of respondents said the man violated the law -- except for respondents who say they were good at math in school, who as a group answered the survey differently from everyone else."
Continue on to see how.

Say a cup of water is 0.25L, and its temperature is being raised from 20C to 100C. That requires 4200 x 0.25 x 80 = 84 kJ
Now lets be really pessimistic on the Google front. Suppose my search takes Google 1 second, and the search is distributed over ten 500W servers. That's 5 kJ expended. Lets double that to allow for the costs of spidering and indexing, and double again since the article mentions two searches per cup. Thats 20 kJ. Assume I spend a minute on my 30W laptop viewing the search results; thats another 2 kJ.
So We have 84 kJ verses 22 kJ.

That should be $3.5M. A lot cheaper than students.
Submission + - Judge Kimball rules; Novell owns Unix copyrights (groklaw.net)
Eggplant62 writes: "In his most damaging ruling yet, Judge Kimball today released his ruling in the SCO v. Novell case, saying that it is his belief that after examining the all the documentation and motion practice and after the hearings earlier this year on various summary judgment motions, the jist is: "[T]he court concludes that Novell is the owner of the UNIX and UnixWare Copyrights." Of course, Groklaw is covering the story and broke the news just over a half hour prior to this submission.
There is also a ruling in SCO v IBM on summary judgment motions but the actual rulings are yet to become available. Keep your eyes peeled."
