Is a bubble coming? Well, is a valuation something passably sophisticated -- or is it a version of "Facebook has 500 million users... how much is a user worth?...oh, say, 100 bucks... presto, $50 billion!"

Maybe Google's IPO idea of "e * appropriate power of 10" lends a false air of accuracy -- all those digits! Not pulled out of thin air either.

PS. Ads? What ads? Facebook has ads?!?

...but even so, was it THAT difficult for a number of US Administrations to realize the strategic inportance of rare earths, instead of standing idle while US production dwindled into nothingness? So now, hello urban mining. Good thing I still have my old cell phones, they might fetch a price.

+ - Moving Monopoles Caught on Camera->

Submitted by Thorfinn.au
Thorfinn.au writes: Science Daily is reporting on magnetic monopoles.
For decades, researchers have been searching for magnetic monopoles — isolated magnetic charges, which can move around freely in the same way as electrical charges. Magnetic poles normally only occur in pairs. Now a team of researchers at the Paul Scherrer Institute (PSI) in Switzerland and University College Dublin has managed to create monopoles in the form of quasiparticles in an assembly of nanoscale magnets and to observe how they move using a microscope at the Swiss Light Source (SLS) to make the magnetic structures visible.
As with the elementary monopoles, which were first predicted by the British physicist Paul Dirac in 1931, each monopole is connected by a "string" to a monopole of opposite charge. The two monopoles can nevertheless move independently of each other. These results are not only of scientific interest, but could also provide a basis for the development of future electronic devices. The results are published online in the journal Nature Physics (Oct. 17, 2010).

Front-running, sub-pennying and similar shady practices are indeed part of the landscape. However, almost all high-speed traders do it. The issue seems (to me at least) to be something else: how to out-do opponent momo (momentum trading) algorithms. There there is room for detecting others' strategies and adapting yours accordingly to gain an advantage.

It is not necessarily a joke. Ordinals do show up in the study of finitary objects. E.g. formal deductions in Peano Arithmetic are finite strings of symbols, but their proof-theoretic analysis leads to countable ordinals up to epsilon_0. Or, the analysis of Goodstein sequences or the Hydra game again proceeds most smoothly by assigning countable ordinals to numbers or tree nodes. Closer to CS, program-correctness work going back to Dijkstra involves ordinals (I still remember him staring at the blackboard working out the order type of a particular case). To be fair, their usage here in the analysis of trading strategies, which are finite AND BOUNDED objects may be a bit of overselling. Enjoy it until HFT gets banned!

After Learning Java Syntax, What Next? 293

Niris writes "I'm currently taking a course called Advanced Java Programming, which is using the text book Absolute Java, 4th edition, by Walter Savitch. As I work at night as a security guard in the middle of nowhere, I've had enough time to read through the entire course part of the book, finish all eleven chapter quizzes, and do all of the assignments within a month, so all that's left is a group assignment that won't be ready until late April. I'm trying to figure out what else to read that's Java related aside from the usual 'This is how to create a tree. This is recursion. This is how to implement an interface and make an anonymous object,' and wanted to see what Slashdotters have to suggest. So far I'm looking at reading Beginning Algorithms, by Simon Harris and James Ross."

Adobe Download Manager Installing Software Without Consent 98

"Not all is worth cheering about as Adobe turns 20," writes reader adeelarshad82, who excerpts from a story at PC Magazine's Security Watch: "Researcher Aviv Raff has found a problem in ADM (Adobe Download Manager) and the method through which it is delivered from adobe.com. The net effect of the problem is that a user can be tricked into downloading and installing software using ADM without actual consent. Tonight Adobe acknowledged the report and said they were working on the issue with Raff and NOS Microsystems, the company that wrote ADM."

New Riddick Movie Made Possible By Games? 160

Hugh Pickens writes "Scott Harris writes on Moviefone that the economics of Hollywood are often baffling, as DVD sales, broadcast fees and merchandising tie-ins balance against advertising costs and pay-or-play deals to form an accounting maze. The latest example is the untitled sequel to The Chronicles of Riddick, released in 2004 to a slew of negative reviews and general viewer indifference. Despite its hefty $105 million budget, most of which was spent on special effects, the film topped out at a paltry $57 million domestically. So how can a sequel be made if the movie lost money? The answer has to do with ancillary profits from revenue streams outside the box office. While the combined $116 million worldwide probably still didn't cover distribution and advertising costs, it likely brought the film close to even, meaning DVD sales and profits from the tie-in video game franchise may have put the movie in the black. In addition, Riddick itself was a sequel to Pitch Black, a modestly budgeted ($23 million) success back in 2000. Extending the franchise to a third film may help boost ancillary profits by introducing the Pitch Black and Chronicles of Riddick DVDs and merchandise to new audiences, meaning that the new film may not even need to break even to eventually turn a profit for the studio."

Google, Apple Call Workers' Race & Gender Trade Secrets 554

theodp writes "The Mercury News reports that Google, whose stated mission is to make the world's information universally accessible, says the race and gender of its work force is a trade secret that cannot be released. So do Apple, Yahoo, Oracle, and Applied Materials. The five companies waged a successful 18-month FOIA battle with the Merc, convincing federal regulators who collect the data that its release would cause 'commercial harm' by potentially revealing the companies' business strategy to competitors. Law professor John Sims called the objections — the details of which the Dept. of Labor declined to share — 'absurd.' Many industry peers see the issue differently — Intel, Cisco, eBay, AMD, Sanmina, and Sun agreed to allow the DOL to provide the requested info. 'There's nothing to hide, in our view,' said a spokesman for Intel. Some observers note it's not the first time Google has declined to put a number on its vaunted diversity — in earlier Congressional testimony, Google's top HR exec dodged the question of how many African-American employees the company had."
