If you do it at the application level... you're re-creating a "deduping" filesystem in higher-level software, with the overhead of being on top of an existing filesystem.
Yes, but if the backup software is cross-platform (as many are), you get portability, which is less common with filesystem drivers (try mounting that ZFS disk on Windows). You also restrict the deduplication performance hit to the backups, instead of anything else on the volume also suffering the hit.
Sure, I agree that backups shouldn't duplicate unchanged data in every backup snapshot. But that would only happen if your "backup software" were literally imaging the drive and storing the images. Nearly every decent piece of backup software already does incremental snapshots, and imo it makes a lot more sense for that functionality to be in the backup system than as part of the filesystem.
Why not just use a better archiver than Time Machine, which includes backup-level deduplication, instead of mucking with the filesystem? Any of the bazillions of incremental-backup solutions based on rsync will avoid putting a new copy of the whole VM image in every snapshot.
If you're running a normal desktop or laptop, this isn't likely to be of great use in any case. There's non-negligible overhead in doing the deduplication process, and drive space at consumer-level sizes is dirt-cheap, so it's only really worth doing this you have a lot of block-level duplicate data. That might be the case if e.g. you have 30 VMs on the same machine each with a separate install of the same OS, but is unlikely to be the case on a normal Mac laptop.
As far as existing films, sure, but they're basically selling the right to make future "Terminator" movies/shows/videogames/sweaters/whatever, which is still worth something.
I think a lot of those are scams too. I've twice been subscribed, without my consent, to junk like that, one a cell-phone dating thing (these doods), and one some ring-tones. I finally got Sprint to lock my account so no subscriptions can be added without me explicitly calling up Sprint to request they authorize it---which should be the default.
In the context of game mechanics I can't think of very many ways in which lead-generation is not trying to scam people.
The most scammy of course is the one here, where people end up getting signed up for some crappy $10/mo service with little/no warning of it. But even if it's a legitimately free one-month trial, which they then have to cancel, it still seems shady with most of the services: they're generally products nobody sane would actually pay for, so it's very transparent that the entire point is hoping that some people will forget to cancel, i.e. trick people into accidentally paying for something that they wouldn't have actually bought.
Maybe free trials for products that someone might plausibly actually buy of their own free will would be acceptable, but I rarely see that in these flash-game types of things. It also still seems out of place as part of game mechanics: just asking people outright to buy your virtual gold is more honest than these roundabout ways of tricking them into paying for your virtual gold.
Yes, but a smoothly flowing continuous stream of water puts considerably less structural stress on a bridge than 250,000 separate cars entering and leaving a bridge.
In this case, it's not really the design lifetime that's a problem--- the bridge, under normal conditions, would continue functioning fine for decades. The problem is that we've gotten less tolerant of things like sections collapsing during earthquakes, and retrofitting the bridge to modern earthquake standards was projected to cost more (incl. the higher maintenance costs continuing indefinitely) than just replacing it with a newer design.
He also routinely votes to exclude pollutants from federal regulation, to raise pollution thresholds or avoid lowering them where they exist, and to insulate companies from liability for pollution. But then, he wants federal pork to bail out Kansas from the effects of such pollution.
It's more that a Kansas senator is pushing for federal pork for Kansas. Roberts wouldn't normally support an environmentalist bill, but in this case, his pro-pork tendencies overrode his anti-environmentalist tendencies.
This seems like kind of a non sequitur. All he said was: photography used to be a major market for silver, but digital cameras and inkjet have destroyed that part of the silver market, since digital cameras and inkjets do not require silver.
It's somewhat ambiguous, but the more likely interpretation is as a second derivative: "decline accelerates" usually means "the rate of decline has increased", not "the rate of increase of the rate of decline has increased".
Indeed, that's their thinking, but they're dishonest about the motives: officially, they say that the native talent simply doesn't exist, not that it exists but only at prices they don't want to pay.
If it was stupid fear mongering that was solved by the 1960s, how did a Soviet satellite in 1978 apparently have insufficient casing to keep radioactive debris from being scattered across Canada upon reentry in 1978?
Surely you wouldn't use nuclear pulse propulsion for the launch, but only once outside the atmosphere, for the interplanetary/interstellar portion of a trip? I think the safety issues are more in how to make designs that don't scatter radioactivity during launch failures.
Well, satellites with nuclear reactors haven't always managed to keep from releasing significant amounts of radiation onto earth. The concerns might be overblown, but as far as I can tell, most scientists do consider the problem of designing nuclear reactors for launch such that they won't leak radiation in a disaster a fairly significant one. It's even been cited (pp. 39-41) as a major motivator for research into fusion-powered spacecraft propulsion, since fusion can in principle achieve similar acceleration characteristics without having to worry about disaster-proofing a payload of radioactive material. (The downside is that we can build lots of fission-powered things today, practically, but not so for fusion-powered things.)
If a sample of videos on YouTube is any indication, it looks like cats are initially curious, but lose interest pretty quickly, so I guess it doesn't pass the cat Turing test for "actual animal". Smelling like rubber and not reacting very quickly to stimuli probably doesn't help with that.
The short of it is: it was an animatronic dinosaur briefly sold from 2007 to 2008, which disappeared fairly abruptly at the end of 2008, apparently due to some corporate shenanigans/infighting (which this article, and the previous ones kdawson links to, document some of).
It's interesting from a tech perspective because it was the first widely available, consumer-priced animatronic pet (that I know of, anyway) that seemed to have some semblance of a personality other than "weird robot thing", so was basically the first at least sort-of-success in that area. It was also hackable.
In addition to using externally developed free software, various parts of the military have periodically released and continued to support some decent bits of software. BRL-CAD is from the Army Research Lab, and Delta3d is from the Naval Postgraduate School, to pick two examples off the top of my head.

Are you wearing some sort of device that causes the distortion field to malfunction?

A list of abusive, lying corporations that includes De Beers on it!
Yes, but taking an arbitrary single-threaded algorithm and automatically figuring out what the parallelization is is the hard part. =]
