Submission + - Improving on Cell-ID localization?

An anonymous reader writes: I am a happy user of the Open CellID database for localization on my none GPS enabled phone. I'm getting around a 600 meters to 1 km accuracy on high density areas, which is pretty good everything considered. I recently stumbled upon an article that describes a method of improving GSM localization without "No additional hardware" or dependence on the mobile carrier. Other methods of improvements described elsewhere are "Enhanced Cell Identification", "TDOA", "TOA", and "E-OTD". My question is this: What method would be the most practical for improving GSM localization?

Best Introduction To Programming For Bright 11-14-Year-Olds? 962

firthisaword writes "I will be teaching an enrichment programming course to 11-14 year old gifted children in the Spring. It is meant as an introduction to very basic programming paradigms (conditions, variables, loops, etc.), but the kids will invariably have a mix of experience in dealing with computers and programming. The question: Which programming language would be best for starting these kids off on? I am tempted by QBasic which I remember from my early days — it is straightforward and fast, if antiquated and barely supported under XP. Others have suggested Pascal which was conceived as an instructional pseudocode language. Does anyone have experience in that age range? Anything you would recommend? And as a P.S: Out of the innumerable little puzzles/programs/tasks that novice programmers get introduced to such as Fibonacci numbers, primes or binary calculators, which was the most fun and which one taught you the most?" A few years ago, a reader asked a similar but more general question, and several questions have focused on how to introduce kids to programming. Would you do anything different in teaching kids identified as academically advanced?

Submission + - Open Source Economics Driving Web 2.0 Innovation (

ReadWriteWeb writes: "Jitendra Gupta looks how the open source model is interacting with our market driven economic system. He writes that the open source movement has become a powerful value creator; that it has created an interesting and somewhat egalitarian wealth distribution mechanism, where on one hand it has made it hard for one stakeholder to extract inordinate rents, and on the other hand it has created the right incentives for a lot of people to participate in, and have a stake in, its success. Indeed, were it not for the LAMP stack, startup costs would have been a lot higher then they are today — and we would not be seeing the amount of innovation we are seeing from web 2.0 startups."

Submission + - No daddy needed

An anonymous reader writes: A team of American and Irish researchers have discovered that some female sharks can reproduce without having sex, the first time that scientists have found the unusual capacity in such an ancient vertebrate species. Analysis of the baby shark's DNA found no trace of any contribution from a male partner. Shark experts said this was the first confirmed case in a shark of parthenogenesis, which derived from the Greek means "virgin birth". Get the scoop here.

Submission + - Japanese Government to Move to OSS

An anonymous reader writes: linuxworld has an article on Japanese government's plan to reduce its reliance on a single IT vendor by moving to open source softwares.

Oracle, NEC, IBM, HP, Hitachi and Dell are among 10 IT equipment and software vendors that are forming a consortium to develop and sell Linux-based servers and computers for the Japanese market. The move by the vendors to collaborate on Linux in Japan comes from a edict from the country's government to make Linux and open source a priority for all IT procurements, starting this July.
Specifically, it looks to reduce Windows as the server OS.

The government has said explicitly it wants to decrease its reliance on Microsoft as a server operating system platform.
