Build 9471 leak comes just a few days before RTM (release to manufacturing)
One of the many criticisms of Windows 8 is that it has a steep learning curve, which is ironic as Microsoft has also been accused of unnecessarily dumbing down its operating system by saddling it with a touch-friendly layer of tiles and apps. The upcoming Windows 8.1 update will thankfully address both issues. While we have already witnessed the ability to skip the Start Screen and boot straight to desktop in earlier builds, a new leaked build contains something that is meant to help first-time users acclimatize themselves to the Windows 8 interface a lot faster.
Mechanical, membrane, and all the Cherry switches explained
So you want to buy a mechanical keyboard, eh? Why is that? Perhaps you’ve heard that they’re the growing rage among gamers and PC enthusiasts – assuming that’s still a “cool” phrase to use. Maybe you’ve gotten your hands on one and, while you’re not quite 100% sure what exactly makes them different from the keyboards you’ve been using, you nevertheless have fallen in love with the mechanical experience. Maybe you have no idea what a mechanical keyboard really is or why it rocks, but you’re interested to find out.
Take a survey of all of your electronics, whether in the computer room or your living room, and you'll likely notice a whole bunch of blue LEDs. Now commonplace, the cost of these little lights might soon be going up.
Citing sources within the LED chip market, DigiTimes says manufacturers are thinking about increasing the ASP (average selling prices) by 10 percent. The reason? The recent surge in demand for LED backlighting has put the squeeze on upstream suppliers who are unable to ship materials on schedule.
In addition to higher prices, Lee Biing-jye, chairman of LED chip maker Epistar, says this year's worst shortage of LEDs will come in the second quarter. He didn't offer up any specific numbers, but current supply is already about 30-40 percent short of demand.
The continued shortage might also be a reason why Samsung is considering lowering its shipment goal for LED-backlit TVs.
Organic light-emitting diodes, or OLEDs have always had three different colors. There are red and green diodes, which currently have a very high efficiency, and then their blue friend, which is about as wasteful as they come.
Thankfully, some brainiacs at the University of Florida have been working nonstop to fix this problem, and they’ve recently re-set the record for efficiency with the diodes. Currently, they’re rocking blue OLED efficiency of 50 lumens per watt, which is halfway to their set goal of 100 lumens per watt.
Franky So, the head of the team has stated that the Gators have “achieved a new record in efficiency of blue organic light-emitting diodes, and because blue is essential to white light, the advance helps overcome a hurdle to lighting that is much more efficient than compact fluorescents.”
