Higher resolution beyond a certain point no longer becomes about displaying more data, but displaying it better. The font remains the same physical size, but more pixels are devoted to it, leading to much crisper, clearer text, without reverting to tricks like anti-aliased and sub-pixel rendered fonts.

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.

Fuel consumption typically increases something less than linearly with vehicle weight. Rolling friction is linear, but at highway speeds, but bulk of friction is from aerodynamic drag, and assuming constant density, aerodynamic drag increases at roughly the 2/3 power of weight. On the other hand, heavier vehicles damage the roadway on the order of the fourth power of weight. As a result, fuel taxes result in passenger vehicles paying a disproportionately high percentage of the cost needed for roadway maintenance.

Actually, if you are working off the premise that gasoline taxes go towards maintenance of the roads, to offset the damage caused by those vehicles, then there should be no taxes on gasoline. Damage done to roadways is typically estimated in terms of axle weight to the fourth power. Your 1500lb/axle sedan is inconsequential compared to that 15000lb/axle semi-trailer, and they're running diesel. A fair tax would tax shipping, which would in turn trickle down to consumers as higher market prices, and serve to motivate improved efficiency in the shipping industry.
