Found Footage: Managing Active Directory with Workgroup Manager
Years ago, Macs didn't even acknowledge the presence of Windows networks, which made those LAN wine-and-cheese parties pretty awkward. Now, however, OS X machines are exemplary network citizens, and apparently can even manage Windows workstations under the right circumstances. TidBITS linked to a roundtable discussion at Cornell University, where Philip Halcomb, of Cornell's Mann Library ITS staff, demonstrated managing user accounts in Active Directory. Now, this wouldn't be very exciting, except for the fact that he was using Mac OS X Workgroup Manager to do it. Sweet. Phil's part starts at about 7:30. It's a long QuickTime video, too -- almost an hour -- but for IT folks, especially in an education environment, the roundtable series is a must-see. (Thanks, MHA, for Phillip's name!)
Cornell Ranger sets unofficial distance walking record for a robot
Think you could keep pace with Cornell's Ranger robot? Just last week, the robot walker set an unofficial world record by trotting nonstop for 45 laps (that's 5.6 miles, for those counting) around the university's Barton Hall running track. After reaching that mark, the creature presumably fell over from battery exhaustion, but the team of creators are investigating to find out the exact reason it finally collapsed. Although Guinness officials weren't involved due to too much "rigmarole," the team has quite a bit to be proud of -- after all, an earlier version of the creature only made it 0.62 miles before calling it a day. Aside from garnering bragging rights, the crew is hoping to use Ranger to better understand the "mechanics of walking," which could be used to improve rehabilitation procedures or even athletic performance.[Via Physorg]
Student Mac ownership at Cornell more than tripled over 5 years
It may have slipped past last month, but Daring Fireball reminded us of September's TidBITS article about the student computing profile at Cornell University. Since 1999, Cornell has required students to report their OS when signing up for Ethernet connectivity in campus housing; prior to '99 the reporting was voluntary. Back in the early 1990s, Mac-using students made up more than a third of the self-announced connected population, but by 2000, after the start of mandatory registration, that number had dropped to only five percent of the base.Times, as they say, have changed. 2007 stats show that 21 percent of the attached student computers are running Mac OS X, a dramatic increase over the past few years. This isn't necessarily a surprise, but it's still nice to see. It also aligns with reports noted by MacRumors yesterday which show dramatic share gains for the platform at other schools, including Princeton (60 percent of on-campus sales this year are Macs), UVA (home of the "BigMac" massively parallel XServe installation oops, that's Virginia Tech, not UVA!) and many more. I guess the old adage is true: when you've got them by the iPods, their hearts and minds will follow.
Cornell designer concocts garb that prevents colds, shuns pollution
We've seen sensor-laden, iPod-friendly, and electroluminescent garb in years past, but a crafty design student over at Cornell University wasn't satisfied with stopping there. Olivia Ong is hoping to get her career in fashion off to a very safe start, as her functional clothing lines include "a garment that can prevent colds and flu and never needs washing," and if that wasn't fresh enough, she's also conjured up another that "destroys harmful gases and protects the wearer from smog and air pollution." The prototype Glitterati garb was showcased at the school's Design League fashion show, and both articles contained "cotton fabrics coated with nanoparticles" that give them the unique qualities. No word on whether or not we can expect such protective (albeit stylish) threads to hit the strip anytime soon, but considering that "one square yard of nano-treated cotton would run you about $10,000," we doubt us common folk would be selling off assets to take it home anyway.

Cornell researchers developing lie-detection software
While most of the world simply takes what everyone else says at face value, there's always been a dark market for inconspicuous lie-detecting gadgetry for the overly paranoid, but researchers at Cornell University are hoping to take lie-detection to the next level by carefully analyzing emails and SMS messages for fibs. In a three-year effort to "compile a list of indicators of written deception," the team drew from some "40 years of research in linguistics and lies, including recent work in the context of computer media and reviews of Enron emails." By carefully inspecting word choices, verb tenses, and a variety of other textual factors, the software can purportedly use "contextual parameters" to spot lies, and they hope to market the goods to police agencies, upset spouses, and of course, corporate ethics committees.So if you're ever-so-suspicious significant other (or mischievous youngster) has just recently put down the Skype headset in favor of pounding out emails, rest assured, help is on the way.[Via TechDirt, image via Cornell]
Cornell robot is "conscious," adapts to injury
Oh great. As if the potent, robotic cocktail of self-replication, self-awareness, and wireless power weren't bad enough, along comes Cornell University with a robot capable of not only discovering its own nature (something we can't even do) but then adapts to overcome injury. This four-legged robot starts out knowing only what parts it has, not where they are or how to use them for locomotion. It applies a scientific method of theory and experimentation to develop computer models and ultimately, a set of commands to turn its motors for that first cautious step. Even when researchers remove part of the toddling robot's leg, the little guy still figures out a way to limp forward. Cornell scientists go so far as to say that the robot is "conscious," albeit on a primitive level since it thinks to itself, "what would happen if I do this?" Yeah, that's a stretch, but a step closer to our doom nevertheless. Although the robot used to demonstrate these cognitive gymnastics is quite simple, the algorithm could be used to build more complex robots for say, space exploration or defending itself while standing in line for a PS3. Well, at least The Robots don't currently have a place to coalesce under a common roof of intellectual ferment... oh God, no! Still, any robot which drinks puddle water can't be too bright, eh?
Solar flares to disrupt GPS for several hours in 2011 or 2012
Ok GPS fans, we're prepping you early for what could be a moment of pretty severe inconvenience in the not so distant future. Brace yourself, because in roughly five to six years, your beloved handheld devices won't work for several hours due to solar flare activity (sound familiar?). According to new Cornell University research, solar flares negatively affect GPS devices, based on observations of stellar phenomena in September of last year. In 2011 or 2012, when the sun reaches its next solar maximum, scientists expect it to cause a 90 percent GPS signal drop for several hours. While most of us will walk around, oblivious to these space fireworks, Alessandro Cerruti (pictured on the left), a Cornell graduate student who studies solar flare effects, envisions this horrific day as a "nightmare situation," given that all planes will likely have GPS signaling by that time. However, given these harbingers of doom, Dr. Paul Kinter (pictured on the right), Cerruti's advisor, has a brilliant solution: "I think the best remedy is to be aware of the problem and operate GPS systems with the knowledge that they may fail during a solar flare." See, it's just that easy, people.
Two-way OLED displays to provide solar power
We've already got plenty of love for OLED. The technology provides cheap, flexible, and even transparent displays to our devices -- what more could we ask for? Well, some research types at Cornell University have developed a new version of Organic LED that not only emits light, but can take in solar energy to produce electricity. We're not so hot on all the science speak they're tossing around to make this possible, but it seems like the technology could be quite an exciting development for all sorts of products, from solar windows to self-charging screens. No word on how long it'll take this tech to go commercial, but they're already talking ways to make mass production a breeze, so that's at least a good sign.[Via Gadgetbox]
Cornell researchers building video projector on a chip
We've seen plenty of tiny projector concepts over the past couple of years, but some researchers at Cornell University are taking this idea to its logical extreme by building a whole display on a single chip. The crux of their idea is basing the device on carbon-fiber, since silicon proves too brittle to handle the 60,000 times a second line-scanning frequency of a traditional video display. Carbon-fiber, on the other hand, can withstand all sorts of abuse and keep on scanning. The chip design has an tiny 400 x 500 micron mirror supported by two carbon-fiber hinges, an array of which -- one for each horizontal line -- would be all that's needed to scan lasers across a screen for a full-fledged video display. Supposedly all this can be squeezed into a form factor small enough to power a cellphone-based projector, and the carbon-fiber springs might even work as a way to harvest energy from user movement for powering small electronic devices. Sign us up for both, please.[Via Slashdot]
Galileo GPS system hacked at Cornell
The insightful minds over at Cornell University's GPS Laboratory aren't messing around -- they only needed one week to hack the GIOVE-A (Galileo In-Orbit Validation Element-A, more commonly referred to as Galileo) and gain access to the European satellite system without those pesky PRN codes. If you're overwhelmed by acronyms, fear not, the jist is as follows: these guys at Cornell did the legwork in developing an algorithm to extract the pseudo random number codes that are used to give customers access to the Galileo GPS system, which unlike America's taxpayer-owned militarily-developed and free GPS setup, is funded by the European Union, European Space Agency, and private organizations (read: service comes at a cost). What those oh so hopeful profiteers obviously disregarded was the little known fact that, well, (right now) it's impossible to copyright physical data about the world, leaving them all but helpless here. So please, should you need access to another set of GPS sats, be our guest and snag all those previously unavailable and presumably costly PRN codes at your leisure.
