Most cable companies have long since dropped analog cable. Time Warner is the only large MSO still offering it.

That's just not true. You're taking one measurement of average human perception, and using it where it does not apply.

The standard "good enough" resolution people quote assume 20/20 vision, or roughly one arc minute of perception, when determining the width of a monochrome line with one eye. If we were viewing monochrome monitors, or ones that at least had their colors in the same physical location, that might make sense, but we don't. A good percentage of the population can see well below 20/20 vision even in this measurement, with the best somewhere around 20/10. That means if 2K is "good enough" for average vision, then 4K would be necessary for those with exceptional vision.

However, that's still wrong. That resolving ability of our eyes might be around one arc minute, but vernier acuity has been measured around eight arc seconds, and stereo acuity has been measured all the way down to two arc seconds. So, maybe once we get another three orders of magnitude pixels, we won't be able to improve it further.

For $189, you're going to get a shitty TN panel. If you actually like the nice image you get from a CRT, or like to view the screen from anywhere but straight on, you won't be happy with it.

Huh? No one has flipped anything. That's just what 4K is. It's a cinema format describing a long axis of roughly 4K pixels. Your current 1080p television could be considered a 2K display.

Not television specifically, no, but we have built crude holographic displays. Now it's just a question of resolution and data rate. Those stored interference patterns are oppressively large.

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.

This is a three year old article? This is a much worse than normal delay for slashdot....

Decades? Plural? Linux has barely even existed for plural decades.

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.

Make that "highly optimizeable"...

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...

Can we at least poison them?

That's Latin. Greek has completely different characters.
