Comment The Demo looks very underwhelming (Score 3, Informative) 43

The Demo looks like it's behind state-of the art tech quite a bit. Their hand-tracking was abysmal (the years-old LeapMotion seems way more precise and quick), the latency was noticeable even under the presumably perfect conditions, HoloLens does the 3D tracking better it seems, and any Android phone can do better graphics with a cheap VR viewer.

It might be impressive that this unit is all self-contained, but this really doesn't seem state-of-the-art at all!

Comment Why did the XMPP/Jabber open protocol fail? (Score 1) 60

A couple of years ago, I was very hopeful that open chat protocols would win - we had Google Talk, WhatsApp, etc. using XMPP (the Jabber protocol) behind the scenes. Some allowed federation (server-to-server connections, allowing inter-network messanges), some didn't. Google was opening libJingle for open source voice (and video?) chats. The demise of closed chat networks seemed imminent.

But somehow, everything went backwards, and now we have dozens of competing IM networks, all with their own incompatible apps and protocols, competing for users, yet again.
Anyone have an idea how that happened?

Comment cheap Arduino clones + meArm + mini servos (Score 1) 78

I used a cheap chinese Arduino clone, and had a (meArm laser-cut from acrylic. Combined it with some very cheap mini-servos from Aliexpress, and I had a very basic robot-arm.
AliExpress is awesome for these electronics things - worldwide free shipping, and the prices are really ridiculously cheap sometimes.
You can then code up some basic code in the Arduino that lets you remote control the servos from a PC with the programming language of your choice (I use perl).
After that, you can e.g. add a 5$ webcam to your computer, to combine your robot arm with basic computer vision, or add some seonsors to the arm, and so on.

Comment F.Lux helps with that on monitors! (Score 4, Informative) 52

Just in case some slashdotter hasn't hear of it yet:
The people between the very awesome F.Lux software have been saying this for quite a while, so their great little software adjusts your monitor's color temperature after sunset, and before dawn, to be 'warmer'. Their logic being that the blue components of white light are just unnatural to stare at at night, and mess up our biorythms.
All sounds a bit esoteric, but I challenge everybody to use F.Lux for a week or so (until you're used to it), and then disable it at e.g. 2am.
Your eyes will bleed, and you wont understand how people can stare into a super bright white square (the monitor) for hours on end at night.

Comment Where does Snowden get all this information from? (Score 2) 192

Could someone explain where Edward Snowden is getting these kind of leaks and infos from, so long after he fled the NSA?

Or was this information, and the other stuff he claimed in the last couple of months, all part of the package he took with him back then?

If he was sitting on this information, then why wait so long to release it?

Or does he have a new source 'inside'?

Submission + - SpaceShipTwo crashes in Mojave desert (space.com)

"Virgin Galactic's suborbital space plane SpaceShipTwo suffered a serious malfunction during a rocket-powered test flight over Mojave, California, today (Oct. 31) resulting in the loss of the spacecraft. The fate of the vehicle's pilot crew is unknown.",

Comment Re:Article mentions me! (Score 1) 26

Sorry to highjack this thread for an OT question, but: Do you know if there is a way to emulate OR DK2's tracking data? I would like to homebrew a very poor man's Oculus Rift. The screen should be no problem, and there are many IMUs available - but how would i get an Oculus-enabled game to read the IMUs data?
