Comment Definitely need better physics (Score 4, Informative) 289

A more substantial problem is that diffraction limits the effective resolution of an optical system to well above the size of each of these pixels. This is a problem with current sensors at narrow apertures; lenses exhibit a measurable loss of sharpness, typically f/11 and up, because the airy disks expand as the aperture contracts. With hugely dense sensors like this, though... plugging some numbers into a website that explains the whole situation suggests that you'd need to shoot with apertures than f/1.8 to get circles of confusion smaller than the size of a single pixel.

That's right--even "fast" f/2.8 lenses are limited by physics to never being able to project detail onto individual pixels. You could potentially add a deconvolution stage in software to recover additional sharpness, but not in hardware.

Another thing. Do the math: the pixels are 2.1 micrometers square. Compare to trichromatic human vision, which detects red light peaking at 564 nanometers, 0.564 micrometers. The size of a pixel is within a factor of four of the wavelengths they measure. Staggering.

Glass isn't the problem. We need new laws of nature, since we're near the edges of the ones we have now.

Journal Journal: PayPal - A Thief's Best Pal?

After posting in my Slashdot journal about how I'd been screwed out of $99 with an auto-renewing subscription and fine print, one commenter suggested I should dispute the charge with PayPal. Yeah, right.

Vista To Be An Indie Games Killer? 113

Via GigaGamez (which has a breakdown of the problem), a GameDaily article about the unfriendliness of Vista towards Indie games. The problem is this: Vista has a setting which allows parents to restrict user profiles from accessing ESRB games 'above' a certain rating. IE: Timmy can't play F.E.A.R., or any other 'M' rated game. The problem is that getting ESRB rated is expensive: '$2000-3000 for the privilege', according to GigaGamez. Shoestring budget Indie games just may not have the money for that kind of expenditure. From the GameDaily article: "'It's unfortunately a mercenary way of doing things,' [GFW Group Manager Chris Donahue] explains, 'but, even though we're Microsoft, we do have limited resources. And we do look at the sales charts to determine where our help will have the most impact. Certainly we want Blizzard's 'World Of Warcraft' [currently the most popular massive multiplayer online game] to work flawlessly on day one of Vista because 8 million tech support calls would be a very bad thing. The casual developers don't sell quite as many.'"
