Linkyt.com has just launched its beta today. The service allows its members to share links with their friends quickly. Users can build a friends list (Linkyt lets you import contacts from your email account which helps speed this step up) and then share links with friends, which can be added to groups, with only a few clicks.
The bookmarklet they provide makes the whole process even faster. If you are on a page you want to share, simply click the bookmarklet in your bookmarks and a new window will take you to Linkyt with the URL already filled out.
The emails sent to friends look professional and clean – much better than doing all this work yourself. We recommend to check out this service and give them any feedback on what you’d like to see in the next version.
If you go outside on August 22nd and start waving at the sky for a few consecutive months*, chances are you might be able to spot yourself on Google Maps in the near future.
On that date, Virginia-based company GeoEye will launch the GeoEye-1 satellite from Vandenburg Air Force Base in California. When it reaches its orbit, GeoEye-1 will start snapping photos of Earth – and it will do so fast. The satellite can take high-resolution photos of an area the size of Texas within a day.
GeoEye-1, holding an ultra high-resolution digital camera attached to a massive telescope, will be able to take clear images of objects just 20 inches across – a huge improvement over Google Earth’s current 3-foot resolution. At this resolution, we should soon be able to see the shapes of people in online maps – but still not license plates. Read more »
The camera is truly, unbelievably tiny and looks more like a kids’ toy than something that can capture stunning high-resolution video.
Of course, the unit comes at a price. It’s only aimed at the pro market for now, for uses such as a hidden camera on a reality show. We’re sure someone will think of other creative uses for this as well.
The company will be showing off its creation at the National Association of Broadcasters convention in Las Vegas this month. Hopefully they can find a way to shrink the cost as small as the camera’s size so we can all be shooting high-def video from tiny camcorders. [via DVICE]
1366 Technologies, founded in part by Sachs, claims that it has improved the efficiency of its new multicrystalline silicon solar cells by 27 percent, putting them on par with today’s standard cells made from single-crystal silicon. Read more »
The system can alert drivers behind you in different ways to show them if you are slowing down, about to stop, and how hard you’re pressing the pedal. It uses a horizontal array of LED lights to create the light show behind your car.
When you begin to slow down, the lights glow orange. After a certain threshold, when you’re about to stop, the side lights glow red. If you’re slamming on the brakes and the cars behind you need to be alerted, the lights will all flash red.
The team behind the project hopes to see their system on commercial vehicles in the future, and we couldn’t agree more. It would take a lot of the guesswork away when driving behind bad drivers. [via Engadget]
Researchers at Big Blue have created a silicon switch that can direct trillions of bits of data each second within an optical network. This switch would make it possible to put a network with the speed and bandwidth of a fiber-optic telecommunications network inside of a computer.
Within the next decade, engineers expect to build computers with tens, if not hundreds, of processing cores. They have not, however, found a way to get the cores to efficiently communicate with each other, as traditional metal wires are simply not capable of transmitting information at the speeds required. The new silicon switch could be the solution to allowing the cores to communicate with each other in a multicore system.
However, the researchers don’t expect the switch to find its way into commercial computers until five or ten years from now. Hopefully they can find a way to integrate it before we get stuck with slow (well, slow for the time) computers. [via Technology Review]
You know all those movies where space travelers are asleep and don’t age a bit while they fly around the galaxy? They’re in suspended animation, and it turns out that this state may actually be possible.
We don’t know how, but scientists discovered that small doses of hydrogen sulfide (found in sewer gas) put lab mice into a state of metabolic suppression within minutes. The mice were able to return to normal within 30 minutes of being able to breathe regular air again.
The scientists don’t know if this will work on humans, although we doubt any human testing will be performed for a while as this is a dangerous thing to toy with. It would be great to see this finding give humans the ability to enter suspended animation and make long space voyages possible. [via Gizmodo]
