F-mount (for Nikon) and K-mount (for Pentax) are indeed very old mount; these two companies did a very good job for preserving backward compatibilities while adding new features to the newer lenses. K-mount is about 30-40 years old while F-mount dated back to the late 50s. Even so some higher-end cameras can get AE with the old lenses without electronic contacts!

Canon current EF-mount is a lot younger. They created the EF-mount in the 80s, which is incompatible to their old line of lenses. Though so Canon they produces a lot of EF-lenses nowadays so you would find it abundant on the market.

Dog Eats Man's Toe and Saves His Life 207 Screenshot-sm

Have you ever been so drunk that you passed out and your dog ate your toe? I haven't either, but luckily for Michigander Jerry Douthett, he has. It turns out Jerry has type 2 diabetes and a wound on his toe had becoming dangerously infected. After a night of drinking Jerry passed out in his chair and the family dog Kiko decided to do a little doggy doctoring. From the article: "'The toe was gone,' said Douthett. 'He ate it. I mean, he must have eaten it, because we couldn't find it anywhere else in the house. I look down, there's blood all over, and my toe is gone.' [Douthett's wife] Rosee, 40, rushed her husband to the hospital where she's a gerontology nurse — Spectrum Health's Blodgett Campus. Kiko had gnawed to a point below the nail-line. When tests revealed an infection to the bone, doctors amputated what was left of the toe."

The f-number which decides the depth of field is the ratio between the aperture and the focal length.

The real reason behind why small sensors does not work well with many pixels, is because it will make less light retrieved by individual pixel sensor (i.e. sensel). Since manufacturer tries to cramp as much pixels on a small patch, the image will worsen especially in low-light environment.

This is why FF (full-frame sensor, 135 film equivalent) and 6x6 (Hasselbrad V-system in TFA) has its market.

Scientists Turn Wood Into Bone 118

Bob the Super Hamster writes "The BBC is reporting that scientists in Italy have developed a method to convert rattan wood into a bone-like substance. The bone replacement is currently being tested in sheep, where, when inserted into the area of a fracture, it joins with the existing bone and eventually fuses. Unlike other bone replacements, this one actually has load-bearing ability and also naturally fuses with the existing bone. Additionally, since it is porous like real bone, nerves and blood vessels can pass through it."

Microsoft Plans Largest-Ever Patch Tuesday 341

from the 24-hours-but-bigger-minutes dept.
CWmike writes "Microsoft said it will deliver its largest-ever number of security updates on Tuesday to fix 13 flaws in every version of Windows, as well as Internet Explorer (IE), Office, SQL Server, important developer tools and Forefront Security client software. Among the updates will be the first for the final, or release to manufacturing, code of Windows 7, Microsoft's newest operating system. The 13 updates slated for next week, eight of them pegged 'critical,' beat the previous record of 12 updates shipped in February 2007 and again in October 2008." Update Reader Kurt Seifried writes to correct the math a bit, pointing to Microsoft's Advance Notification page for the release, which says that rather than 13 flaws, this Patch Tuesday involves "13 bulletins (eight critical and five important), addressing 34 vulnerabilities ... Most of these updates require a restart so please factor that into your deployment planning."
