There's a few. I've read there's a patchset for ZFS on FUSE that can do deduplication; there's also opendedup and lessfs. The problem is that none of these has been around long enough to be considered bulletproof yet, and for a filesystem whose job is to play fast and loose with file contents in the name of space savings, that's kinda worrisome.
Actually, it is automatic. ZFS already assumes you have a multithreaded OS running on more cpu than you probably need (e.g. Solaris), so it's already doing checksums (up to and including SHA256) for each data block in the filesystem. Comparing checksums (and optionally entire datablocks) to determine what blocks are duplicates isn't that much extra work at that point, although for deduplication you probably want to use a beefier checksum than you might choose otherwise, so there is some increase in work.
http://blogs.sun.com/bonwick/entry/zfs_dedup has some more information on it.
Getting it onto my linux box, now.. there's the rub. userspace ZFS exists, but I've only seen one pointer to a patch for it that includes dedup, and I haven't heard any stability reports on it yet.
Actually, this feature is a recent addition to ZFS, and it's the main reason I'm interested in putting ZFS on my file server. I just have to get around to picking up another drive to serve as the backup first.
I know when I was 16 that if someone had tried to suppress my rights to speak my mind, defend myself, or reserve my privacy both of my parents would have been up in arms about it.
Sounds like you had some awesome parents. Unfortunately, all three of those things are rather sharply restricted for minors, at least on school property, and (in the minds of many adults) most other places as well, if those rights conflict with how the adult wants the world to be.
Bad news. That last word in clause B is 'or'. That means that it's going to get read as 'matches A or matches B or matches C', which toasts your "ALL the criteria" assertion.
Nah. It'd still be a terrible idea, even though it would also be the best option. (This is not a unique combination. "Democracy is the worst form of government except for all those others that have been tried." - Winston Churchill)
At this point I pretty much consider "electable" to be an insult, implying "too boring to offend the public and too spineless or brainwashed to be rejected by the party wheels."
Do you really expect "you don't have to have this for things to work but it's safer" to get the market penetration that "you have to have this to work" does?
There is also, I recall reading, a set of immune system genes that appear to be activated by the presence of hepatitis A (a relatively benign strain, transmitted in poop) which used to be ubiquitous, and is now getting pretty rare. Unfortunately I cannot find a citation for this effect, so this may have been refuted.
3D does nothing inherently to do that, true. Likewise color didn't inherently help with the stories that had been told in black and white. But over time, filmmakers will learn ways to use the new feature to say things they couldn't have said without it. In the meanwhile, gratuitous use of 3D will continue, hopefully not too painfully, until it stops being novel enough to make back the extra costs of filming that way.

The patent does not use the word 'film' anywhere. It does, however, use 'storyline recorded on an electronic medium'.

My film prof claimed it was essentially a western :)
Might be hard to pull the unobtanium out of the resulting slagpile, though.
An even better reason to have incompatible fittings (as well as color coding. Coding makes matchup faster, fittings make it error-resistant).
I think his definition of 'isn't working' is more of 'takes more effort on my part than I feel like'.

Seems perfectly consistent to me: I want the backbone provider to put whatever bits I want on the wire I helped pay for.
