How To Tell When Gmail Is Back Online For Good (GOOG)

Google acknowledged today that several services, most notably Gmail, experienced outages.

So far, it looks like Gmail is coming back for a lot of people, but some are still having trouble using the chat feature and other basic functions. 

Google has a very handy chart that shows what services are currently operational. You can get the latest updates using the official Apps Status Dashboard. Green means you're good to go. Gmail is still listed as "orange" as of this writing.

Here's what it looks like:

This Custom Datacenter Rack Has 160 Mac Minis Crammed Inside of It

Source: http://gizmodo.com/5967189/this-custom-datacenter-rack-has-160-mac-minis-crammed-inside-of-it

If you're hankering for an Xserve, you've been out of luck since 2011. But there's always an alternative. You can make your own by squeezing a whole 160 Mac Minis into a custom rack, for instance. That's what a fellow named Steve did, and the results are staggering.

Working with a vendor to get some custom shelving, Steve got his hands on 40 special 1U shelves that hold 4 Minis each. Of course, that wasn't the only challenge. Each Mini had to be fit with a special plastic insert to insure it wasn't drawing intake air from the 159 other Minis' exhaust ports, and the door of the rack was fitted with four car radiator fans, all hooked up to a 40A DC motor controller.

The result is this impressive—if crowded—tower of power, packing some 640 cores, double the amount of the 40 Xserve setup it's replacing. While Steve's reluctant to say who he works for, he's stated on his blog that the monster is part of a huge server farm, building and testing software 24/7. How's that for a Mac hack?

Researchers devise contact lens with built-in LCD (video)

Another day, another step towards technologically tricked out contact lenses. The latest development comes from researchers at the Centre of Microsystems Technology at Ghent University, who've developed a prototype lens with an embedded, spherical curved LCD that isn't limited to a paltry amount of pixels. As opposed to LED-based solutions which could only muster a few pixels, the newly-developed screen can pack enough to display graphics that cover a contact. In its current form, the display can show simple patterns, and demonstrates the technology with a simple dollar sign. What appears on the lens wouldn't be visible to folks who wear it, however, since eyes can't focus at such a close range. Despite the limitation, researchers are tying to tackle the focusing issue and are assessing the feasibility of a version that would effectively act as a heads-up display. In the future, the tech could be leveraged for medical purposes, such as controlling light transmission to the retina when the iris is damaged, cosmetic uses and -- you guessed it -- HUDs. With the technol! ogy's fo undation established, it's expected that real-world applications are potentially a few of years away. Hit the jump to catch a video of the tech in action.

Arduino Esplora helps you learn microcontrollers without the pesky breadboard

Source: http://www.engadget.com/2012/12/10/arduino-esplora-learn-microcontrollers-without-the-breadboard/

Arduino is the go to board for most folks looking for an introduction to microcontrollers. That's largely thanks to its sizable community, ease of use and surprising versatility. But, there is one small stumbling block for those just looking to dip their toes in the ATmega-powered waters: you'll need to provide your own sensors, components and breadboard. (At least you will unless you're satisfied just making the built-in LED blink.) The Esplora bakes some of those essential bits and pieces right on to the board. It's crafted around the same core as the Leonardo, but adds an accelerometer, microphone, analog joystick, four buttons, a light sensor, temperature sensor, linear potentiometer and a buzzer to the mix. While the gamepad-like layout means you wont be able to connect to any of the dozens of Arduino shields out there, it does have a pair of TinkerKit inputs and outputs for expanding the Esplora's capabilities. There's also a place to connect an upcoming LCD module. The Esplora is available now direct from Arduino for €41.90.

Silicon Image reveals Ultragig 6400 wireless HDMI output for next-gen phones and tablets

Source: http://www.engadget.com/2012/12/10/silicon-image-ultragig-6400-wirelesshd/

Up 'til now, the WirelessHD standard has been best suited to large, thirsty devices like laptops, AV adapters and projectors. If we wanted video output from a battery-powered weakling of a mobile device, then we'd either be looking at a WiFi-based option, which can sacrifice bandwidth and latency, or at a wired connection like MHL, which effectively means tethering ourselves to the TV. However, Silicon Image claims it's come up with a new WirelessHD transmitter, the Ultragig 6400, which allows for gaming and full 1080p60 video and yet is easily light-footed enough to fit into a smartphone or tablet.

The company's optimistic photoshop above shows off the compactness of the module relative to the type of flagship phone it'd one day like to be part of: the silicon itself is 10mm x 7mm in area, or a fifth the size of the older WirelessHD Gen3. Just as importantly, the 60GHz transmitter consumes less power than a smartphone's own local display (around 500mW, with a 30-foot line-of-sight range), has a mere 5ms latency to allow for interactivity, and shouldn't add more than $10 to the cost of manufacture. Of course, we'd have to add a little more to th! at sum i n order to purchase the mains-connected HDMI receiver box -- but in return we'd get to enjoy all our mobile vices at something much closer to life-size.
