Comment Re:The R language and its uses (Score 5, Informative) 382

I second that. R is terribly useful for the wide variety of libraries available and esoteric statistical procedures. But you would *never* want to write a long/complex program in R.

As you say, it's most convenient to work in some other language that's actually designed to be scaleable, object-oriented, and easy to debug. It's usually straightforward to call R libraries when you need them. I find that python+scipy+rpy is an almost ideal environment for day to day scientific programming.

If a company has no potential to issue dividend then it is worth nothing and should be shorted into oblivion.

Yes, and if everyone was perfectly rational, the market would be completely efficient and we would live in a utopia. In the real world, sudden price drops in small companies trigger panic-selling. Investors often move with the herd-- they don't have time to do all the research into a company's fundamentals and make an independent evaluation of a stocks worth. When there is a sudden price drop, all the think is "damn, better cut my losses now, because all these other guys now something is wrong with this company."

There should be regulation to make it exceedingly difficult to trigger panics by naked short-selling. Regular short-selling isn't so bad.

Google Reveals Wireless Vision — Open Networks 90

Anti-Globalism writes with this excerpt from CNet: "Google's vision of tomorrow's wireless network is in stark contrast to how wireless operators do business today, setting the two sides on a possible collision course. Earlier this week, the search giant filed a patent application with the US Patent Office describing its vision of an open wireless network where smartphones aren't tied to any single cell phone network. In Google's open wireless world, phones and other wireless devices would search for the strongest, fastest connection at the most competitive price. Essentially, wireless operators' networks would be reduced to 'dumb pipes.'" The full patent application is available as well. Google founder Larry Page recently asked the FCC to free up portions of the broadcast spectrum for this purpose.
