Comment Re:frequency hopping and better navigation. (Score 1) 134

Except this isn't a problem that needs solved.

Kinematic GPS solves position using the carrier instead of the (time) code. Since the carrier length is ~19cm you're instantly much tighter than is possible solving with the time code.

And, as others above me have said, (regardless if you're carrier or code locked) a 3D solution needs four birds visible because of the receiver's inaccurate clock. At best an atomic clock on the receiver means one less variable to solve for = one less bird needed. Today when we have a full constellation that is just about never a problem unless you're in absolutely horrible terrain with very high horizons, and in that situation your PDOP is going to be so bad as to render moot any positional accuracy gains seen by better clocking.

Not to mention the Russian GLONASS birds up there, and Europe's if they ever get their act together, and the L2C frequency... point is there are lots of inexpensive ways to increase accuracy which don't rely on an expensive clock chip.

The time to short the stock is well past.
One shorts when public information is low and you have special knowledge of the situation, be that insider information, a unique knowledge of the industry, or particular experience.

Shorting Sony at this point in time, when all the smart money (which knows more than you) has already set a rational price based on reasonable odds is nothing more than tying your hands.

Unlike a traditional (long) position you would have locked yourself into a time window, preventing you from a full range of actions based on later information.

Comment Re:Why not just deploy a Robot to take the shot? (Score 1) 265

I hear what you're saying regarding vision, and while that wasn't the limitation I was thinking about upon further thought perhaps you are right.

I was thinking about the (currently) uniquely human ability to judge range and wind through a combination of complex and subtly visual clues, rules-of-thumb, intuition and experience (the way tall prairie grass responds to a 10mph wind in late dry summer is different than how it responds the day after a rain, etc). There is no reason, though, that a sufficiently complex expert-system paired even with today's camera technology probably couldn't do the same.

In all seriousness; how long until the military just deploys (via parachute drop, or soldier) robots into decent vantage points and then just get them to identify targets and have a remote operator push the button... scary stuff.

The value of a sniper team is not just in their targeted lethality, but also in their scouting, observation abilities, and ability to move. A robosniper limited to a fixed position is just as much a sitting duck as a static artillery tube.

A robot which finds its own cover and provides a remote control gun barrel might be within the limits of modern (or foreseeable) technology, but one which is capable of moving stealthily from spot to spot? One which can climb stairs and over rubble in a bombed out building in the afternoon and craw through a drainage ditch that night? One which is able to read the wind and range passively without giving away their position through the radiation of active sensors? No, I don't think such a robot will be seen in my lifetime, likely not my (unborn) children's.

As it stands now savvy users can simply check out a epub library book to their PC with Adobe Digital Editions, seamlessly remove the DRM with calibre, then convert and upload to their Kindle with one-button via your Kindle's free email address. If Amazon doesn't make their service work without a PC I've gained nothing.

I almost died of the analysis-paralysis suffered looking for an ebook reader, and finally settled on the Kindle as the best bang for the buck today. While I feel epub is the future (especially now that google has weighed in) with calibre I Just Don't Care.

Comment Re:HE-AAC is worse than LE-AAC in terms of quality (Score 3, Interesting) 166

The sad thing is it shouldn't be better than HE-AAC. Being low latency does tend to mean one is better at the kind of time-domain issues many find so objectionable, but outside that OPUS is really packing a MUCH smaller toolkit than HE-AAC.

This is really egg on AAC's face, IMHO, and quite the upset. OPUS is so immature the bitstream isn't even stable yet.

Comment Re:HE-AAC is worse than LE-AAC in terms of quality (Score 5, Insightful) 166

HE-AAC uses SBR to reduce its data footprint. This results in worse reproduction of the source audio than LE-AAC at same bitrate (and often even lower bitrate). The whole deal with HE is that it can maintain good quality at very low bitrate, by giving up accuracy. So far, Apple's LE-AAC encoder in their Core Audio framework is the best choice for digitally non-lossless compression.

While your rant appears informative if not insightful on its face, it is completely missing the point.

This is a test of audio codecs at low bitrates.

I don't know what this "LE-AAC" is you speak of (and rather suspect you don't either) but AAC-LC was actually in this test, as the low anchor.

At these bitrates (~64kbps) HE-AAC (despite its "low-accuracy" as you put it) is perceptually better sounding than AAC-LC. Lossy audio codecs (even the LE-AAC [sic] encoder in Apple's Core Audio framework you love) can only be judged by how they sound, not how they look. "Accuracy" is not a metric very worthy of discussion.

From TFA,

The adjustable beam is typically one degree wide

So for this to be effective, you have to aim fairly precisely at someone's eyeball. Presuming they aren't cooperating by standing stock-still with their eyes open and looking at you, the chances of managing a "hit" before they do whatever it is you would prefer they didn't must be quite small.

The angular diameter of the full moon (or the sun) is just about half that, and I think you'll find that is plenty large to paint a face quickly and easily.

Nope. U3 "crapware" works because a U3 flash drive mounts with two USB endpoints, one of them identifying itself as a CD drive. All the autorun "magic" of U3 happens from the CD-ROM endpoint.

Or...you know....they just didn't find the problem. Considering that it only happened to be about 4 times within a 3 year time span, a few months of testing won't necessarily reproduce the problem.

A few months times dozens of drivers and hundreds of vehicles, including every single one with a unexplained reported sudden acceleration problem they were able to get their hands on.

If you had reported your sudden acceleration issue to your dealer the NHTSA would have contacted you.

Since you didn't mention the fact of their contact, much less the method which all of us in the loop should know, I call BOGUS.
