Comment Re:Cataract will fluoresce green (Score 1) 311

Thanks; I'll check my vitamins for lutein and zeaxanthin. I'm a vegetarian, but a bad one - I'm really more of a pastafarian - so I probably don't get enough anything from dietary intake! FWIW, the silicone hydrogels allegedly let in far more oxygen than hydrogels, although at the moment all the data I'm finding is a physics model saying that's not true and some very strong marketing from hydrogels claiming it doesn't matter.

I've been sleeping in my extended wear lenses as well, and I've worried I'm taking a theoretical risk. Were these modern disposable silicone hydrogels, or the older extended-wear kind? As I understand it, cataracts arose as a side effect of microbial keratitis, and the risks of a severe infection are lower with silicone hydrogels (as well as with disposables in general).

What sort of eye nutrition do you recommend?

Network Solutions is, in fact, a horrible registrar for corporate domains. This winter we changed our DNS from NetSol to Amazon Route 53. When NetSol repoints domains, it *immediately* starts serving generic "parking page" A records from the old DNS server. Combine this with the fact that many ISPs ignore the SOA TTL record, and you have a domain that's down for over a day for your customers at BellSouth, Cox, RCN, and probably others. We did get them on the phone, and was told "that's the way it works".

Why is 44kHz seen as sufficient to capture all that information?, let alone the complexity of a song?

Because you're thinking of the samples as "points along a line, which I can use to approximate the original wave." The power of Nyquist is that it's not an approximation; those points are sufficient to reproduce the EXACT waveform. A better way to think about it is this:

There is only one waveform that goes through exactly those points. Given those points, you know which waveform it was.

Think of a simpler version: Instead of sine waves, use a straight line. All straight lines are of the form y = mx+b. I have two samples: (1,2) and (2,4). I now have all the information in the original line. Not some of it, not an approximation, not an estimate - ALL of it.

Nyquist/Shannon says that if your sample rate is greater than twice the highest frequency, you have ALL of the information.

I've been wondering if it was ever litigated. The actual language is:

A statement that the information in the notification is accurate, and under penalty of perjury, that the complaining party is authorized to act on behalf of the owner of an exclusive right that is allegedly infringed.

It sounds like the penalty of perjury might only apply to whether you're acting on behalf of the copyright owner, not about whether the information is accurate.
