HIV Transmission Captured On Video

Technology Review has promising news on the AIDS front: researchers have captured HIV T cell transmission on video. The upshot could be new avenues of treatment. “The resulting images and videos show that, once an infected cell adheres to a healthy cell, the HIV proteins… migrate within minutes to the contact site. At that point, large packets of virus are simultaneously released by the infected cell and internalized by the recipient cell. This efficient mode of transfer is a distinct pathway from the cell-free infection that has been the focus of most prior HIV studies, and reveals another mechanism by which the virus evades immune responses that can neutralize free virus particles within the body.”

RIP the Campus Computer Lab, 1960-2009

theodp writes “When every student has a laptop, why run computer labs? That’s a question schools have been asking themselves as computer ownership rates among incoming freshmen routinely top 90%. After only four freshmen showed up at the University of Virginia in 2007 without a computer of their own, the school decided that it’s no longer worth the expense of running campus computer labs. Student computer labs have been a staple of campus life since the ’60s. So what are the benefits that will be missed as other schools follow UVa’s lead?” The university’s report notes understanding that “that students need collaborative space where they can bring their laptops and mobile devices to conduct group work, especially as the curriculum becomes increasingly team- and project-based.” One of the spaces formerly occupied by computer labs “has been transformed into a technology-rich collaboration area.”

Windows 7 Touchscreen Details Emerging

nandemoari writes “Microsoft has revealed more about Windows 7 and its support for touch screen technology. The system sounds impressive, however, reports suggest it appears to have a high error rate. In an early version of the system, Microsoft found some problems. For example, both the zoom and rotate functions worked less than 75% of the time, often because the computer confused the two. To rectify this, engineers redesigned the system so that it only looks out for gestures specifically relevant to the program being used. This made a significant improvement: the zoom gesture was now recognized 90% of the time. The problem is that even a 90% success rate may be too low. If you can imagine how frustrating it would be if one in ten keystrokes or mouse movements didn’t do what you intended, you can see why touch screen technology will need to be even more reliable if it’s to truly improve the user experience. PC Authority has a related story about statements from HP, who don’t expect such technology to replace keyboards and mice any time soon.”

3D-Based CAPTCHAs Become a Reality

mateuscb writes “A new way of creating a CAPTCHA using 3D objects has become a reality. The idea was thought up independently by blogger Taylor Hayward and by the folks at YUNiTi.com. ‘Similar to Hayward’s idea, this new technology relies on our ability to identify objects in 3D instead of using alphanumeric characters. YUNiti’s 3D Captcha, however, has three objects in the challenge and extends the list of images to any object, not limiting it to animals as in Hayward’s idea. This increases the challenge’s level of complication to prevent computers from successfully making the correct guesses.’ I, for one, welcome the thought of not having to read more and more complex CAPTCHA. Lately, I’ve been having a hard time getting CAPTCHA to work the first time.”

Microsoft, Amazon Oppose Cloud Computing Interoperability Plan

thefickler writes “Microsoft is opposing an industry plan, the Open Cloud Manifesto, to promote cloud computing interoperability. Officially, Microsoft says the plan is unnecessarily secretive and that cloud computing is still in an early stage of development, but there are allegations that Microsoft feels threatened by the plan because it could boost Linux-based systems. The goal of the group behind the manifesto, the Cloud Computing Interoperability Forum (CCIF), is to minimize the barriers between different technologies used in cloud computing. And this is where the problem seems to lie, with the group stating that ‘whenever possible the CCIF will emphasize the use of open, patent-free and/or vendor-neutral technical solutions.’ Some speculate that Microsoft is actually worried that this will allow open source systems, such as Linux, to flourish, at the expense of Microsoft technology.” Amazon is also declining to support the plan, saying, “the best way to illustrate openness and customer flexibility is by what you actually provide and deliver for them.” Reader smack.addict contributes a link to an O’Reilly piece asking what openness really means for cloud computing.

Laser Sniffing Captures Typed Keystrokes From 50-100 Feet

Death Metal writes “Chief Security Engineer Andrea Barisani and hardware hacker Daniele Bianco used handmade laser microphone device and a photo diode to measure the vibrations, software for analyzing the spectrograms of frequencies from different keystrokes, as well as technology to apply the data to a dictionary to try to guess the words. They used a technique called dynamic time warping that’s typically used for speech recognition applications, to measure the similarity of signals. Line-of-sight on the laptop is needed, but it works through a glass window, they said. Using an infrared laser would prevent a victim from knowing they were being spied on.” (This is the same team that was able to pick up the electromagnetic signals emitted by PS/2 keyboards.)

10 OSes We Left Behind

CWmike writes “As the tech community gears up to celebrate Unix’s 40th birthday this summer, one thing is clear: People do love operating systems. They rely on them, get exasperated by them and live with their little foibles. So now that we’re more than 30 years into the era of the personal computer, Computerworld writers and editors, like all technology aficionados, find ourselves with lots of memories and reactions to the OSes of yesteryear (pics galore). We have said goodbye to some of them with regret. (So long, AmigaOS!) Some of them we tossed carelessly aside. (Adios, Windows Me!) Some, we threw out with great force. (Don’t let the door hit you on the way out, MS-DOS 4.0!) Today we honor a handful of the most memorable operating systems and interfaces that have graced our desktops over the years. Plus: We take a look back at 40 years since Unix was introduced.”

History of the Internet in a Box

If you had to store three petabytes of data and keep it online for the entire Internet community, and you wanted to save space and energy, what would you do? For the Internet Archive, the answer was simple: Put the data in a Sun Modular Datacenter (Sun MD) equipped with Sun’s Open Storage technology.
