Improved Image Quality For HMDs Like Oculus Rift

flowerp tesselate polygons, then warp in vertex shader ? (55 comments)

Hi,

Can't one just subdivide (tesselate) polygons that appear relatively large in screen space so that they consist of many small polygons, with a few pixels each? This would allow for doing the barrel distortion entirely in the vertex shader with no ray tracing being required. The challenge is to perform the dynamic tesselation without requiring a constant updating of the geometry (vertex buffers) on the GPU.
Maybe newer APIs like DirectX10 or 11 would support this dynamic tesselation approach in hardware.

Google's Crazy Lack of Focus: Is It Really Serious About Enterprise?

flowerp payouts come later (226 comments)

Look at what they did with Android. Seemed like a crazy project at first, but now they're essentially owning the market for mobile operating systems.

So let them do their unfocused things, because some of them will pay out big later.

Einstein@Home Set To Break Petaflops Barrier

flowerp 1000.2 TFLOPS reached! (96 comments)

I added two nVidia GTX 260 and one nVidia GT 240 card to Einstein @ Home , and voila this morning's stats show:

Page last updated 3 Jan 2013 8:50:02 UTC
Floating point speed (from recent average credit of all users) 1000.2 TFLOPS

For a BOINC novice it can be quite daunting to figure out how to make it use all GPUs and not accept any CPU-only work units. Editing some XML files in some data directory isn't exactly user friendly.

Increasing Wireless Network Speed By 1000% By Replacing Packets With Algebra

flowerp Re:too specialized on a single protocol? (357 comments)

I did not miss anything here.

If I send a video stream as a sequence of UDP or RTP packets, clumping together to perform some kind of forward error correction is perfectly possible and reasonable.

When you invent some kind of solution to prevent packet loss on wireless links, it should apply to all kinds of IP traffic and not single one protocol.

Increasing Wireless Network Speed By 1000% By Replacing Packets With Algebra

flowerp Re:This only works end to end (357 comments)

And in case you want to read about the changes they made to TCP, here's the paper:
http://arxiv.org/pdf/0809.5022.pdf

The paper mentioned in the summary only does a performance evaluation for this TCP
dialect, but is light on details.

Increasing Wireless Network Speed By 1000% By Replacing Packets With Algebra

flowerp This only works end to end (357 comments)

This is why I think this will not catch on easily. You can't just put a new router with their coding functionality into your home and expect this to work. It also needs support from the server hosting the content you want to acces.

The way they designed their system is end to end. Meaning that the internet server has to run a modified TCP stack and the client system (alternatively your router inbetween) also has to understand this modified TCP dialect.

The chance of millions of Internet servers changing to a (likely) patented, proprietary version of TCP is ZERO.

This is why this idea will fail.

Black Duck Eggs and Other Secrets of Chinese Hacks

flowerp The article draws weird conclusions. (220 comments)

My wife has no problems buying black eggs of any kind in asia stores in Germany. Oh, and black eggs can be mailed long distance, it's fermented and thereby preserved food.

And you really can't conclude from the menu of a chinese restaurant what's going or not going on behind the scenes. I call bullshit on this one. No corporate espionage ring would need to use a "safe house" or "safe restaurant" for that matter to drop off secret information or to secretly meet. It's the information age, dummies!

The Science of Avatar

flowerp TFA is full of flaws itself (275 comments)

First, Pandora does have an oxygen atmosphere, or how else could you explain the burning torch that Jake Sully lights up in self-defense against the wulf-like creatures at night?

Second, the floating mountains are explained by assuming that the rock is made up of superconducting material ("Unobtainium") and that the flux they keep talking about is actually a strong magnetic field. Superconductors tend to hover in magnetic fields, you know.

Most Complete Topographical Map of Earth Complete

flowerp Flight simulator users rejoice! (207 comments)

Getting an accurate world elevation map essentially for free is really cool. Previously you had to get one of the commercial scenery DVDs that would set you back at least $50.

After all, having realistic mointain terrain makes flying much nicer and recognizing land features will be much easier. Then map some Sat terrain on top, for example with the Tileproxy application and everything will look just real.
