Injectable Artificial Bone Developed 105

An anonymous reader writes in with the news that British scientists have invented artificial "injectable bone" that flows like toothpaste and hardens in the body. This new regenerative medicine technology provides a scaffold for the formation of blood vessels and bone tissue, then biodegrades. The injectable bone can also deliver stem cells directly to the site of bone repair, the researchers say. "Not only does the technique reduce the need for dangerous surgery, it also avoids damaging neighboring areas, said [the inventor]. The technology's superiority over existing alternatives is the novel hardening process and strength of the bond... Older products heat up as they harden, killing surrounding cells, whereas 'injectable bone' hardens at body temperature — without generating heat — making a very porous, biodegradable structure."
It's funny.  Laugh.

Mystery Science Theater Turns 20 165

RimmerExperience writes "Hard to believe that Mystery Science Theater 3000 is 20 years old. This NY Times article provides a brief synopsis from the humble but inspired beginnings in a Midwest TV studio, to the making of MST3K: The Movie, to what the creators are up to today. It's interesting that the original creators are still involved in MST3K-style riffing in some way. So if you are looking for your traditional Turkey Day fix, plug in your old VHS, tune into BitTorrent or check out their current projects — Riff Trax (Mike Nelson) or Cinematic Titanic (Joel & Trace). Keep circulating the tapes, er, MPEGs."

By convention, "lock-free" is sort of an ill-defined term that roughly means "no software-based locking operations, except maybe we'll ignore spin-locking, provided the algorithm always makes global progress while spinning occurs." In any case, there is no common definition for "lock-free" which implies the absence of hardware locking.

I'm not sure there is anything radically new in this project. However, given the exceptional difficulty of writing correct lock-free algorithms, just about any project exploring this area is noteworthy.

Journal Journal: London Law devel

London Law was mentioned on Slashdot late last year. Development had stalled after the 0.2.0 release back in February, as I was sinking my limited hobby programming hours into Wyrd. A couple of months ago I polished off a respectable 1.0 release of Wyrd, so I've recently been putting some time in on London Law

Journal Journal: Version Control Developments 4

I've been using various iterations of GNU Arch for a couple of years now. tla was among the first free distributed version control systems, and Tom Lord's design had a lot of things going for it: history-sensitive merging, cheap branching, proper handling of renames, append-only repositories, full operation over dumb transports like http and sftp, etc. There's no question, it's
