Hands-On With Microsoft's Touchless SDK

il y a 10 heures 30 minutes
snydeq writes "Fatal Exception's Neil McAllister takes Microsoft's recently released Touchless SDK for a test spin, controlling his Asus Eee PC 901 with a Roma tomato. The Touchless SDK is a set of .Net components that can be used to simulate the gestural interfaces of devices like the iPhone in thin air — using an ordinary USB Webcam. Although McAllister was able to draw, scroll, and play a rudimentary game with his tomato, the SDK still has some kinks to work out. 'For starters, its marker-location algorithm is very much keyed to color,' he writes. 'That's probably an efficient way to identify contrasting shapes, but color response varies by camera and is heavily influenced by ambient light conditions.' Moreover, the detection routine soaked up 64 percent of McAllister's 1.6GHz Atom CPU, with the video from the Webcam soon developing a few seconds' lag that made controlling onscreen cursors challenging. Project developer Mike Wasserman offers a video demo of the technology."

How Should I Teach a Basic Programming Course?

il y a 11 heures 38 minutes
riverman writes "I have been 'provisioned' at the school where I work to teach a new Computer Science/Programming course. I'm supposed to be teaching everything from the very-very basics (i.e. where that myspace thing is in your computer monitor, and how it knows who your friends are) to the easy-advanced (i.e. PHP classes and Python/Google App Engine). I'm an experienced programmer, but I'm not sure where to start — I could easily assume that my students know something basic they don't. Are there any resources on the internet that could help me find a solid curriculum? What are your suggestions?" I'm sure many of us have gone through intro-level programming courses of some sort; what are some things your teacher or professor did that worked well, and what didn't work at all?

Looking for Earth-Like Exoplanets

il y a 12 heures 47 minutes
Discover Magazine is running a story detailing the search for planets like Earth orbiting other stars. While we've been able to locate a few "super earths" so far, none of them really compare in size or the potential for habitability with our own world. Fortunately, advances in data analysis and new space-based telescopes — such as Kepler, the James Webb Space Telescope, and the already-launched CoRoT (PDF) — have some astronomers predicting we'll find such an exoplanet by 2010, and a habitable one by 2012. Earth-based telescopes are also in the hunt, though the article notes, "even if a habitable Earth-like world is found first from the ground, it will most likely take a space observatory to search for the chemical signals that tell us what we really want to know: Is anything living out there? If the planet is one that can be observed transiting, it just might be possible to provide a hint of an answer in the next few years."

EMP Shielded Power Grids Under Development

il y a 13 heures 53 minutes
An anonymous reader writes with this excerpt from MarketWatch: "A one-megaton nuclear bomb detonated 250 miles over Kansas could cripple many modern electronic devices and systems in the continental US and take out the power grid for a long time. ... A solar storm similar to the one that occurred in 1859, which shorted out telegraph wires in the United States and Europe, could wreak havoc on electrical systems. Each of the above scenarios can create a powerful electromagnetic pulse that overloads electronic devices and systems. IAN staff and Frostburg State University physics and engineering professor Hilkat Soysal are teaming — through a $165,000 project recently approved by the Maryland Industrial Partnerships (MIPS) program — to create renewable energy-powered, electromagnetic pulse (EMP)-protected microgrids that could provide electricity for critical infrastructure facilities in the event of a disaster." Also available are an EMP threat assessment (PDF) written for the US Congress and an estimation of economic impact (PDF).

British MoD Stunned By Massive Data Loss

il y a 17 heures 45 minutes
Master of Transhuman writes "Seems like nobody can keep their data under wraps these days. On the heels of the World Bank piece about massive penetrations of their servers, the British Ministry of Defense has lost a hard drive with the personal details of 100,000 serving personnel in the British armed forces, and perhaps another 600,000 applicants. This comes on the heels of the MoD losing 658 of its laptops over the past four years and 26 flash drives holding confidential information. Apparently the MoD outsources this stuff to EDS, which is under fire for not being able to confirm that the data was or was not encrypted."

UK Government Says More Spying Needed

il y a 20 heures 54 minutes
An anonymous reader writes "Our wonderful government here in the UK has decided we're not being surveilled enough, and agreed to spend £12 billion on a programme to monitor every Briton's phone calls, e-mails, and internet usage. According to various sources, upwards of £1 billion has already been spent on the uber-database. Rationale? Terrorism, of course (no prizes for guessing). Needless to say, not everyone is as happy as Larry over this: Michael Parker pointed out how us Brits are being 'stalked.' I'm just looking forward to when the data gets lost."

Sprint's Xohm WiMax Network Debuts In Baltimore, Works Well

ven, 2008/10/10 - 21:42
bsk_cw writes "Sprint's newly launched Xohm service is now offering America's first WiMax network. Computerworld's Brian Nadel went to Baltimore to try it out, and he reports that Xohm delivered data smoothly to a car moving at highway speeds, played YouTube videos flawlessly, and on average, pushed through more than 3Mbit/sec., compared with 1.3 Mbit/sec. for the AT&T network Brian used as a comparison. But right now, coverage is only planned in a few US cities; if Sprint isn't able to ramp up its coverage quickly, it may lose its advantage."

How US Schools' Culture Stifles Math Achievement

ven, 2008/10/10 - 18:18
Zarf writes "I'd like to file a bug report on the US educational system. The New York Times reports on a recent study that shows the US fails to encourage academic talent as a culture.'"There is something about the culture in American society today which doesn't really seem to encourage men or women in mathematics," said Michael Sipser, the head of M.I.T.'s math department. "Sports achievement gets lots of coverage in the media. Academic achievement gets almost none."' While we've suspected that the US might be falling behind academically, this study shows that it is actually due to cultural factors that are devaluing the success of our students. I suspect there's a flaw in the US cultural system that prevents achievement on the academic front as valuable. Could anyone suggest a patch for this bug or is this cause for a rewrite?"

Choosing a Replacement Email System For a University?

ven, 2008/10/10 - 17:27
SmarkWoW writes "The university I attend is currently looking to change the way in which is provides its students with an email service. In the past they used a legacy mail system which can no longer fit their needs. A committee has narrowed the possibilities down to three vendors: Google, Microsoft, and Yahoo. Representatives from these three vendors will be coming to our college and giving a presentation on the advantages of their systems. We're looking at other services these companies provide such as calendaring and integration with existing software that our university runs. What questions would Slashdot readers ask during these Q&A sessions? Which of these three companies would you recommend? Why? What advantages would each have that college-level students would take advantage of? What other aspects should we consider when making our decision?"

Artificial Gecko Adhesive, Now in Experimental Glue

ven, 2008/10/10 - 16:45
thefickler writes "Scientists at the University of Dayton have created a peel-on, peel-off glue which mimics the wall-climbing abilities of Spiderman. The substance, based on the feet of the Gecko lizard, is three times stickier than existing adhesives. The material is so strong that a 4×4mm pad would be enough to hold a 1.5kg object such as hardback book. However, it's likely too expensive for consumer use: one British scientist calculates that a single Post-it note using the glue would cost around a thousand dollars." We've mentioned the possibilities of synthetic gecko technology several times before, including as applied in this wall-climbing robot; commercial applications have seemed just around the corner for a while now.

Verizon To Charge Content Providers $.03 Per SMS

ven, 2008/10/10 - 15:12
An anonymous reader writes "It appears that Verizon is going to start double-dipping by charging both consumers AND content providers for SMS text messages. Verizon has informed content partners that it will levy a $.03 charge for messages sent to customers, effective November 1. From RCRWireless: 'Countless companies could be affected by the new fee, from players in the booming SMS-search space (4INFO, Google Inc. and ChaCha) to media companies (CNN, ESPN and local outlets) to mobile-couponing startups (Cellfire) to banks and other institutions that use mobile as an extension of customer services.'"

Verizon Exposes the Wrong 1,200 Email Addresses

netbuzz writes "If you're going to market your expertise by inviting 1,200 IT professionals to a seminar about securing data and protecting personal information, it's probably a good idea to protect the personal information of those you invite. On Tuesday, Verizon forgot that advice and blasted each of the 1,200 email addresses to everyone on the list ... and they did it 17 times."

20 Hours a Month Reading Privacy Policies

ven, 2008/10/10 - 09:59
Barence sends word of research out of Carnegie Mellon University calling for changes in the way Web sites present privacy policies. The researchers, one of whom is an EFF board member, calculated how long it would take the average user to read through the privacy policies of the sites visited in a year. The answer: 200 hours, at a hypothetical cost to the US economy of $365 billion, more than half the financial bailout package. Every year. The researchers propose that, if the industry can't make privacy policies easier to read or skim, then federal intervention may be needed. This resulted in the predictable cry of outrage from online executives. Here's the study (PDF).

Judge Tosses Telco Suit Over City-Owned Network

ven, 2008/10/10 - 08:23
tsa sends along news of the city of Monticello, Minnesota, which was sued by their local telco, Bridgewater Telephone Company, because the city chose to build a fiber optics network of their own. The judge dismissed their complaint of competition by a governmental organization. Quoting: "The judge's ruling is noteworthy for two things: (1) the judge's complete dismissal of Bridgewater Telephone Company's complaint and (2) his obvious anger at the underfunding of Minnesota's state courts. Indeed, the longest footnote in the opinion is an extended jeremiad about how much work judges are under and why it took so long to decide this case."

Walmart Caves On DRM Removal

cmunic8r99 writes in with an email he received from walmart.com yesterday evening about the pending shutdown of their DRM services (which we discussed a while back). Walmart has reconsidered and won't be shutting off its DRM servers after all. They are still moving to an all-MP3 store, but won't break all the DRMed music its customers have already downloaded; this because of "feedback from the customers."
