Overlay, xv? that's a nice feature thanks. It used to use a fixed fonction scaler I think, at least in S3 Virge, ATI Rage Pro, and took YUV as input. It's what made our PCs smooth at full screen video till flash video tried to ruin it, requiring a 1GHz and faster CPU to play low quality vids. Did they remove the old scaler, while adding new fixed function stuff? (h264 etc.). That would feel stupid to me.
Xv is still around.
There's a bit of confusion over the meaning of background noise. In this example, it's not stray sound or RF, but reflections from things you don't care about. For dolphins, they're talking about air bubbles in the water. For this RADAR system, they're talking about brush and rubble. The idea of differential signalling does not apply here.
Basically, they're sending two pulses, shifted 180. They both bounce off the target, come back, and cancel each other out at the receiving antenna, yielding no response. It acts like a material discriminator, in that certain interesting materials, such as wires or micro-circuitry, invert only one of the reflections, so instead of cancelling each other out, they amplify.
Why this inversion of only one of the reflections happens, rather than both... I have no idea. I'm merely repeating the claims in article.
As you say, it does need time to mature, but the library of games is already there. This is the actual Unreal 3 engine, with limited modifications. It uses WebGL and asm.js. WebGL is a means of accessing graphics hardware through Javascript, and is based on OpenGL ES. asm.js is a subset of Javascript, limited to structures that are highly optimization, and generated by a custom backend to a C compiler.
Basically, with limited effort, you can port any C/C++/OpenGL game to the web browser.
Well... there's always the Unreal tech demo...

especially because there is a correlation between MPG and vehicle weight, and vehicle weight has a strong influence on road deterioration.
Actually, there isn't. Fuel consumption increases with vehicle weight at a power less than one, while road deterioration increases at a power around four.
