If you have TRULY observed a fly trying to find its way around a house, you might have noticed that it in fact takes a very GRACEFUL approach: it never bumps to anything but almost completely transparent objects (as do many birds), and its true grace can be readily observed through 1500 fps videos.

It is one of the animals with the highest flight maneuverability, as two of its wings have evolved to counterweights: not only it can hover and take-off backwards, but it can land upside-down, and does so very skillfully. See youtube and BBC documentaries for further edification.

One: laser ring gyros instead of mechanical accelerometer or visual head tracking systems two: Render a frame larger than FOV and digitally move that before the next frame is rendered.

Not hard.

The first costs on materials, power and research, and the second requires loads of processing power. Cheap compared to the cost of, say, an F35, but expensive for consumer electronics (which I gather is the point for this article).

For your edification as an armchair specialist on laser ring gyroscopes, framebuffers and all things VR, may I suggest that you at least bother to multiply the number of bits per pixel times the number of pixels times the FPS, to at least get a handle on how much data needs to be processed and understand the problem before you post.

+ - New Version of Kelihos Botnet Appears->

Submitted by Trailrunner7
Trailrunner7 writes "Researchers are tracking a new version of the Kelihos botnet, one that comes complete with better resistance to sinkholing techniques and a feature that enables it to remain dormant on infected machines for long periods to help avoid detection. The botnet also is using an advanced fast-flux capability to hide the domains it uses for command-and-control and malware distribution.

This is the third time the Kelihos botnet has reared its head. The first two instances, security researchers were able to sinkhole the domains that Kelihos was using, effectively crippling the attackers' ability to communicate with infected machines. The first Kelihos botnet takedown in 2011 was a joint effort between Kaspersky Lab and Microsoft and the teams were able to reverse-engineer the communications protocol that the bots use. Kelihos, also known as Hlux, is a peer-to-peer botnet, meaning that there is no central server or servers that spit out new commands for the bots."

Hesh writes "The space-pirates themed Project Holodeck game (http://www.ProjectHolodeck.com) out of USC is a VR game that is initially targeted for the Oculus Rift and will marry VR with a world so interactive and immersive that it feels like you can almost reach out and touch it. Ben Lang over at RoadToVR recently got a chance to sit down with the team and try it out and came out extremely impressed with how immersive the experience was: '...at one point I needed to set the Razer Hydra controllers down to adjust my helmet and I nearly tried to set them down on a virtual table next to me. There was no table in real life — had I not quickly realized what I was about to do, I would have dropped the controllers straight onto the floor below.'"

+ - Used Ebooks, the Ridiculous Idea that Could Also Destroy the Publishing Industry->

pigrabbitbear writes "Amazon has a patent to sell used ebooks. When I first scanned the headline, I thought it must be some Onion-esque gag, and I'm sure I wasn't alone. Used e-books? As in, rumpled up, dog-eared pdfs? Faded black-and-white kindle cover art, Calibri notes typed in the margins that you can't erase?

Barely-amusing image aside, used ebooks are for real. Or at least have a very real potential to become real. See, Amazon just cleared a patent for technology that would allow it to create an online marketplace for used ebooks--essentially, if you own an ebook, you would theoretically be able to put it up for sale on a secondary market.

The approved patent describes the process:

Digital objects including e-books, audio, video, computer applications, etc., purchased from an original vendor by a user are stored in a user's personalized data store ... When the user no longer desires to retain the right to access the now-used digital content, the user may move the used digital content to another user's personalized data store when permissible and the used digital content is deleted from the originating user's personalized data store."
