The Dirty Business of Assembling WiMAX Spectrum 101

go_jesse writes in to make us aware of a MarketWatch article reporting on the battles that WiMAX partners Sprint and Clearwire are fighting — sometimes with one another — to put together enough spectrum to fill in their planned WiMAX coverage map. The problem is that decades ago the FCC passed out licenses in what would become the WiMAX band to schools and non-profits nationwide. Once Sprint began knocking on their doors asking to license their spectrum — once they began seeing dollar signs in a forgotten resource — dozens, then hundreds of these organizations applied to the FCC to renew long-dormant licenses. The FCC has granted the first of these requests and Sprint has asked it to reconsider. Confusingly, Sprint's partner Clearwire has sided with the schools and non-profits. The article sheds light in one messy corner of the battle to provide a "third pipe" into US consumers' homes.

A Case Study In GPLv2 / GPLv3 Compatibility 239

An anonymous reader writes "A project called OpenChange is working to develop an open source client library for Microsoft Exchange. They are heavily dependent on Samba code for the underlying protocol support and have been forced to move to GPLv3 once Samba moved. This has gotten in the way of legally adding support to other software such as KDE, which is unwilling or unable to go GPLv3." It sounds like all the developers involved expect the GPLv2/GPLv3 issues to be resolved in time.

Update: 10/01 12:26 GMT by KD : Dan Shearer, of OpenChange and the Samba Team, wrote in to correct the anonymous submitter's mistaken implication that OpenChange moved reluctantly to GPLv3. Read on for his actual position.

Virgin Digital To Close Up Shop 207

mrspin writes in to note the demise of the Virgin Digital music store. Here is Virgin's announcement. It will shut down in stages: the service closed its doors to new subscribers on Friday; current subscribers will lose all access to it when their next monthly payment is due or on Oct. 19, whichever comes first. The store advises customers who have purchased downloads to back them up to CD and re-import them as MP3. It used to discourage such DRM-evading tactics.

The Rise of the Linux-Based Cellphone 151

mrscotty99 writes with a link to a Linux.com article about the rising star that is the Linux-based cellphone. Author Murry Shohat argues that the transformation of the cell into a mini-PC this summer is a landmark opportunity for Linux. Apple's offering and Motorola's US launch of the RAZR2 V8 (a linux-based device) may be heralds of great things to come for a new OS frontier: "In the cell phone market, consumers will pay for content, and corporations need to deliver secure content to applications in the palm of employees' hands. These trends suggest products that are simultaneously more functional and less expensive than a Treo or BlackBerry and more secure than an iPhone. MontaVista Software claims to have deployed Mobilinux on more than 35 million mobile devices worldwide. CEO Tom Kelley says, 'Linux is growing rapidly on mobile devices because of its solid reliability, its great flexibility, and because it accelerates the development cycle.' Vendors using or contemplating the use of Linux for mobile devices unanimously point to the operating system's footprint, memory usage, and fast growing ecosystem of developers producing software for graphics, multimedia, connectivity, and security."

Submission + - Algorithm Rates Trustworthiness of Wikipedia Pages

paleshadows writes: Researchers at UCSC developed a tool that measures the trustworthiness of each wikipedia page. Roughly speaking, the algorithm analyzes the entire 7-year user-editing-history and utilzes the longevity of the content to learn which contributors are the most reliable: If your contribution lasts, you gain "reputation", whereas if it's edited out, your reputation falls. The trustworthiness of a newly inserted text is a function of the reputation of all its authors, a heuristic that turned out to be successful in identifying poor content. The interested reader can take a look at this demo (random page with white/orange background marking trusted/untrusted text, respectively; note "random page" link at the left for more demo pages), this presentation (pdf), and this paper (pdf).

Submission + - Infrared radiation: The other wireless technology

StonyandCher writes: Although the recent auctioning of the 700MHz wireless spectrum bands have garnered great interest in the media (not to mention the billions of dollars being thrown around to own some of this), it's not the be-all and end-all answer to our wireless hunger.

New research is starting to be conducted in the area of infrared radiation. Cheap to develop infrastructure for, super fast and with huge amounts of spectrum available (literally many terahertz), is this the unlicensed answer to the dearth of wireless spectrum? This article delves deeper into the world of IR and looks at its pros and foibles.

Scientists Offer New Way to Read Online Text 404

An anonymous reader writes "Scientists at a small startup called Walker Reading Technologies in Minnesota have determined that the human brain is not wired properly to read block text. They have found that our eyes view text as if they're peering through a straw. Not only does your brain see the text on the line you're reading, but it's also uploading superfluous information from the two lines above and the two lines below. This causes your brain to engage in a tug of war as it fights to filter and ignore the noise. The result is slower reading speeds and decreased comprehension. The company has developed a product that automatically re-formats text in a way that your brain can more easily comprehend."

Is Commercialization Killing Open Source? 162

An anonymous reader writes "IBM, Sun, Novell, and Red Hat all have a very significant open source element to their businesses. In addition to these juggernauts, there is growing investment in various open source models. Will money flowing into open source destroy its roots? Mark Hinkle just posted an editorial asking the questions Is Commercialization Killing Open Source? in which he comments on 'opensville' and gives some actual investment data, and a lot of insight into the growing trend in 'open source commercialization'. Is there such a thing as 'too much money' when it comes to developing software?"

SQL-Ledger Relicensed, Community Gagged 194

Ashley Gittins writes "Users of the popular accounting package SQL-Ledger were being kept in the dark about a recent license change. Two weeks ago a new version of the software was released but along with it came the silent change of license from GPLv2 to the 'SQL-Ledger Open Source License' — presumably in an effort to prevent future forks like LedgerSMB. As it turns out, the author was making deliberate attempts to prevent the community from finding out about the license change. No posts to the SQL-Ledger mailing lists asking about the license change were getting past moderation and direct questions to the author were going unanswered. Just recently the license was switched back to GPLv2. This behavior is not a first for this particular project, and is part of the reason for the original LedgerSMB fork. Does a project maintainer have an ethical obligation to notify his or her community of a license change? What about a legal obligation?"

A Look at the Compiz and Beryl Merger 250

invisibastard writes to mention that Linux Tech Daily has an editorial on the merger between Compiz and Beryl. "This state of affairs was a shame. Something that was finally getting the general public excited about Linux, the 3D desktop, was wasting time with duplication of effort and fighting. There were concerns about the long term viability of Beryl. The perception in the community overall was, Compiz = old and stale, Beryl = fresh and exciting. This despite the feeling in the Compiz community that the "real work" was being done by David Reveman and Compiz, and there were exciting things with Compiz core (like input redirection, etc...) on the horizon."
Education

Future Game Coders - Online Education or College? 143

An anonymous reader asks: "My cousin is about to graduate high school and wants to enter the game industry. I told him to get a day job (possibly as QA in a game studio) and get an online degree like DeVry's Game and Simulation Programming degree or The Art Institute of Pittsburgh's Game Art & Design degree. I have a BS and an MS in Computer Science, and I've only found what I learned mildly useful for my game programming hobby. Should he suck it up and get a 4-year degree, or is taking online courses focused on game development the way to go? Has anybody gotten one of these degrees and done well for themselves?"
Data Storage

Digital Big Bang — 161 Exabytes In 2006 176

An anonymous reader tips us to an AP story on a recent study of how much data we are producing. IDC estimates that in 2006 we created, captured, and replicated 161 exabytes of digital information. The last time anyone tried to estimate global information volume, in 2003, researchers at UC Berkeley came up with 5 exabytes. (The current study tries to account for duplicating data — on the same assumptions as the 2003 study it would have come out at 40 exabytes.) By 2010, according to IDC, we will be producing far more data than we will have room to store, closing in on a zettabyte.

30 Days With Ubuntu Linux 852

jkwdoc writes "Vexed by Vista's hardware requirements and product activation issues, many have claimed on various boards that they plan to 'switch to Linux.' [H] Consumer spent 30 days using nothing but Ubuntu Linux to find out if this is truly a viable alternative for the consumer. Linux has indeed become much more than the 'Programmer's OS.'"
Encryption

Submission + - Final AACS key found

julie-h writes: The PowerDVD AACS private key for playing Blu-Ray and HD-DVD's have been found. This was the last key needed. What does this mean? We don't have to sniff/snoop Volume IDs anymore. We can create a program that can decrypt (or play if you will) a disc without any need for WinDVD or PowerDVD. So no sniffing/extracting of keys anymore. And more over: it can work on all platforms... In other words: we can make our own independent, user friendly player (or decrypter).

Getting Out of Tech Support? 152

An anonymous reader asks: "For the last year or so I've been working in 1st line tech support at a small call centre that's part of a much larger outsourcing company and to be honest it's sucking the life out of me, I want change but I don't know what direction to take in order to get out and I really need some advice from others who have made the jump. I suppose what I'd like to know is what kind of jobs one should be looking for coming from technical support with decent knowledge of UNIX, networking, scripting and 'light coding'. Is there any hope for me or will I have to go back to school in order to even have employers look at my resume?"
