You are right. My brain wasn't properly engaged.

Yes, that's an interesting aspect of evolution: since UV light was harmful the cornea changed to block it, but having those extra photorreceptors didn't harm so they didn't disappear :-)

Retinas _this_ way around are also damaged by UV light, specifically the longer wavelength UVA as UVB and UVC are stopped at the cornea. What's even more interesting: less than 1% of UV light reaches the retina because it is blocked at the cornea. I highly doubt that putting all that mess in from of the photorreceptors will have a noticeable effect on retinal degradation.

...the name you know.

And it's part of the job of musicians to know how their music is going to be published. OTOH, PCM is not as "universal" as the GP thinks. I have seen some problems with PCM because two computers had different bit-endianness.

You can use the € HTML entity. It's a bit longer to type but it should work to get a nice €

Troll harder.

Erm... pounds aren't a weight measure.

I suspect Phobos will be fucked earlier: it is expected to collide with Mars or break up into a disk in about 50-100 million years.

"...involuntary dilation of the... iris?"

A billion is a million million for everyone but a few misguided individuals ;-)

Thanks to both for your answers. It seems I misread this article about the limits of quantum computing.

AFAIK, quantum computing algorithms are only able to square root the complexity. IOW, since the best factorisation algorithms are exponential, you only need to double the key length to stay safe agains quantum computers.

I repeat: as far as I know. Feel free to correct me if I'm wrong.

Which is why you can:

Of course, pasting a link is such a hard task... I can't understand who ever thought hypertext would ever be useful.
