Yes, but I'd like it to 3,840 x 2,160 resolution video at 120 or 240fps.

You realize that's 24 gigabits/second *minimum* just for 4K 120fps raw video, right? (With 4K's better color, it might be 32 Gbps, I'm not sure.) That is not a trivial challenge.

or just 2160p as it should be called

Movies come in different aspect ratios. At 1.78:1 you get 1080p or 2160p. At the also popular 2.35:1 you get ~817p. 720p likewise becomes ~544p. Those aren't really helpful for comparison since 817p isn't lower resolution than 1080p. Only the horizontal resolution is constant, so it actually makes sense to use it. The use of vertical resolution comes from the days of analog TV when only horizontal resolution was continuous, not discrete.

(I'm sure the marketing folks were salivating over it anyway.)

Also, while I haven't watched your hour-long video (summary?), I'm not sure why anyone would target 4096 pixels wide, which would make upscaling existing HD very painful. Doubling the resolution is much simpler, and I very much doubt that 4K was ever a spec as opposed to a marketing term.

Have you seen the price of gold recently?

We're talking microns of gold plating on the surface of another metal. If you're paying more than a few dollars extra for that, it's not the gold that's driving up the price.

That being said, I agree that digital signals and error correction along with electrical and mechanical standards make cable quality almost irrelevant.

Every jurisdiction effectively picks and chooses which laws it's going to enforce and when. It's called "prioritizing". And sure enough, that's what the feds are doing:

The memo directs federal prosecutors to focus their resources on eight specific areas of enforcement, rather than targeting individual marijuana users, which even President Obama has acknowledged is not the best use of federal manpower.

The moral and legal value of prioritization is in the results (i.e. who gets targeted and who gets ignored), not the act itself.

Comment Re:Weird choice of measurements (Score 5, Informative) 85

Accuracy measures how close the frequency is to the target, on average. Stability measures how the frequency drifts over time (and temperature, etc.). Accuracy is more of an absolute measurement while stability is more of a relative measurement. From the article:

The ticks of any atomic clock must be averaged for some period to provide the best results. One key benefit of the very high stability of the ytterbium clocks is that precise results can be achieved very quickly. For example, the current U.S. civilian time standard, the NIST-F1 cesium fountain clock, must be averaged for about 400,000 seconds (about five days) to achieve its best performance. The new ytterbium clocks achieve that same result in about one second of averaging time.


[U.S. civilian standard cesium reference clock] NIST-F1's performance is described in terms of accuracy, which refers to how closely the clock realizes the cesium atom's known frequency, or natural vibration rate. Accuracy is crucial for time measurements that must be traced to a primary standard. NIST scientists plan to measure the accuracy of the ytterbium clocks in the near future, and the accuracy of other high performance optical atomic clocks is under study at NIST and JILA.

So it sounds like accuracy is defined in terms of how well the clock reproduces the ideal frequency of the physical process it's based on. Hopefully there's a physicist or two around who can give us the exciting details.

How many times do we need to see this "coincidence", of a comet diving into the sun, followed by an instaneous CME, to at least calculate the probability of CMEs being caused by comets vs not caused by comets?

If you watch the video, you'll see that the CME happens well before the comet hits the sun.

Sarah's Google+ post has an update:

Update: Looks like this is an xHCI specific issue, and probably not the cause of the USB device disconnects under EHCI. To everyone who commented with other USB issues (none of which really sounded related), please email the linux-usb mailing list with a description of your issue.

Provide 1280 peacekeepers.

Receive compensation from UN of $1.3M. Profit > $1M/month.

Take-home pay is not the only expense. Flying people back and forth to the other side of the world and keeping them supplied is not free, especially in a place with minimal infrastructure. Whatever profit Nepal is making, I doubt it's over $1M/month.

The Visual Display of Quantitative Information has many examples of slick-looking graphics going back decades, long before computers were any good at graphics. How to Lie with Statistics is even older than that. Newspapers and news magazines have always been infamously bad at showing data. It's a rare data graphic that doesn't focus on decoration over content, and that's ignoring the ones that are deliberately distorted.

That being said, most software (I'm looking at you, Excel) is way too helpful about creating bad data graphics.
