MIT figured out how to 3D print using glass instead of plastic

Researchers at the Massachusetts Institute of Technology unveiled a new 3D printing method on Friday that employs transparent glass as precursor instead of plastic. The method, called 3DGP, works basically the same way that conventional 3D printing does though the team found that they could modulate the light transmission, reflection and refraction qualities by precisely varying the thickness of the print.

The system uses a pair of heated chambers stacked atop one another; the 1900-degree F upper chamber acting as a Kiln Cartridge and the lower chamber serving to anneal the constructed structures. Researchers at MIT Media Lab collaborated with the school's Mechanical Engineering Department, the MIT Glass Lab and Wyss Institute to create the 3DGP. The team believes that method could eventually lead to better quality and less expensive fiber optics.

Playdate: Walking blindly into 'Everybody's Gone to the Rapture'

Source: http://www.engadget.com/2015/08/20/playdate-everybodys-gone-to-the-rapture//

Welcome back to Playdate, where Engadget runs through the latest games while broadcasting them live on Twitch. If you're feeling a bit of déjà vu that's entirely natural; you have been here before. Whereas JXE Streams was our awkwardly named show while we figured out what was going to happen with streaming moving forward, well, we've figured out what we're doing with streaming moving forward. Mostly. Hence us going back to the moniker we started with last year. Think of this as a vote of confidence from us that we're moving toward consistency and normalcy for our broadcasts. It's a good thing!

And what better way to do that than by exploring the mystery of Everybody's Gone to the Rapture? Tune in at 6 pm ET/ 3 pm PT (barring any jank) as Sean Buckley and myself plod through developer The Chinese Room's latest game absolutely blind. Neither of us have played it before, read any reviews or know really anything about the game other than it looks absolutely stunning thanks in no small part to the developer's use of Cryengine. Oh, and as an extreme juxtaposition, we're breaking Rapture's tranquility to give away five codes for the incredibly frantic Call of Duty: Black Ops 3 multiplayer beta on PlayStation 4. There may be a haiku contest involved so get your syllable-counting fingers ready.

So, join us here on this post, twitch.tv/joystiq or the Engadget Gaming homepage and follow along as we try to figure out exactly what happened and how to get to The Rapture.

We're streaming Everybody's Gone to the Rapture through OBS at 720p on PS4, so rest assured that the game looks much prettier in your house and on your TV.

LG bets that OLEDs are the future of displays

Source: http://www.engadget.com/2015/08/17/lg-invests-billions-in-oled//

It's no secret that LG has been fond of OLED screens as of late, but the company is now proving that it's committed to those organic displays for the long haul. It's investing the equivalent of $8.5 billion into developing OLED technology over the next three years for everything from TVs to cars to wearables. LG only describes this as a bid to "pioneer this untapped OLED market" and "keep the competitors at bay," but it's not hard to see a few reasons why it'd pour cash into this relatively exotic technology -- and it's not all about one-upping Samsung.

The move is certainly necessary for cars and wearables, where flexible OLED is important for putting displays on less-than-flat surfaces. However, LG is also doing this to resist the race-to-the-bottom trend in screen pricing, especially in the TV space. Like 3D and 4K, OLED gives LG a reason to ask a premium for that giant TV or banana-shaped smartphone -- it doesn't have to compete as much on price. That effect will only last for so long -- OLED TV prices have fallen rapidly in the past few years -- but it could keep LG ahead of the pack (or at least, near the front) for a little while longer.

This drone can steal data while hovering above your office

Source: http://www.engadget.com/2015/08/17/hacking-drone//

It's the job of a security researcher to figure out how the company they are working for could be compromised. Apparently that now means using a drone sniff out vulnerabilities a few dozen feet off the ground. The Aerial Assault drone houses a raspberry Pi running Kali Linux, a distro built specifically for penetration testing (also known as pen testing) of networks and devices. Once in the air, the spy drone can detect insecure devices and networks and store that information locally or beam it back to the pilot.

The Aerial Assault drone is built on top of open source technology so researchers can purchase and adjust it to work in a way that suites their needs. Because it uses GPS, in addition to hanging outside of skyscrapers collecting unencrypted data, it can also be sent out to multiple buildings in areas that would be inaccessible by a person. For example; a courtyard in the middle of a complex or building behind a very large fence with razor wire.

While the craft is intended for researchers, there's always the possibility that someone with fewer scruples could purchase it and use it to steal data from an individual or company. So if you're feeling a bit safer about your system because you're 30 floors up, think again. The $2,500 drone should be on sale in the next few days at Wall of Sheep. If you're super impatient, you can hit up the site's sales team via email.
