How do you distinguish between intentional and unintentional changes? How much storage overhead do you need to keep all changes so that you can roll back any unintentional change?
I'm only a rocket scientist, not a CS person, but it seems intuitive to me. If it's an intentional change, then the new version will have a later last-modified date than the back-up. If the hash of the back-up copy made at the time it was written matches a hash calculated at the time of the second back-up, then the integrity of the back-up is confirmed. If the active copy has not been intentionally changed in the interval, and its hash no longer matches the other two, then the active should be discarded in favor of the back-up. I'm sure you can do the mental figuring for the equivalent to detect if the back-up rather than the active has bitrotted.
The challenge arrives if you have *both* intentional and unintentional changes to the same file between successive back-ups. To exclude unintentional changes, you would have to do hashes every time you save/compile/whatever,as well as keep a keystroke log of the edits. Then, you would have to execute the exact same change process on the back-up copy, repeating the process described above. It would be incredibly resource-intensive (essentially having a 'bot duplicate the work you have performed between back-ups), but it would sure be thorough.
Lord, I HOPE this is not an original idea. If I just invented it, and somebody tries to patent it later, you're in for a world of hurt.

Please provide a link to any mainstream working application for Mac OS X that uses Qt. I don't know of a single one because Qt's support for XCode is incredibly poor.
calibre. Extremely popular in the ebook community. And I have never used the language, but I imagine that you're correct about the issues. Qt on MacOS must be a real PITA, because I've had to submit bug reports for problems that I could have avoided using just Applescript.
But the truth is the original three movies didn't (and still don't) need any prequels/sequels/bollocks.
After the first movie came out, I was actually quite intrigued, and looking forward to seeing what the "Clone Wars" were about. From the name, there was clearly a fascinating story to be told about the morality and ethics of cloning, that must have led up to a huge, all-encompassing holy war on the order of Dune's Butlerian Jihad. The Clone Wars may or may not have been connected to the fall of the Republic; Obi-Wan's original tale to Luke was ambiguous. There was some intriguing fan fiction positing that cloning could have led to the corruption/dissolution of the Jedi Order (taking advantage pun-like naming opportunity through characters called "OB-1" and "OB-2.")
The "Clone Wars" we got were anything but. The fact that the events leading up to the rise of the Empire would still be called "The Clone Wars" a generation later is still something I can't wrap my head around. Why in the name of all that's holy aren't these events known as "The Trade Federation Uprising," or "Collapse of the Republic?" Clones were only a portion of the action, and certainly weren't what the war was about.
Considering the HEADLINE just told us that the Rubik's Cube isn't meant to be a toy, then the summary went and compared it to 'other toys' which have been around a long time, I'm going to go with the Rubik's Cube as the odd one out.
Not exactly. Slinky wasn't originally a toy either.
I hit Goodwill (thrift store) and picked up a home Clear branded WiMax modem/wireless router. The thing runs on 12 volts, so a DC cord instead of the wall wart makes it very mobile on a home dataplan.
Does it work while in motion? (track from tower to tower)?
Maybe grammatically, but not logically. It's just as annoying as seeing announcements/posters for the "First Annual XYZ event." When something happens, and there is no proof of anything following, using the word "first" makes no sense.
Yeah, but at least you can get the most significant five of those on DVD and Blu-Ray, and the four of the five on the Blu-Ray are in full 24p HD. Scott and the studio seem to comprehend the importance of retaining the archival versions.
Here in Houston, that is accomplished with a paper receipt that you put on your dashboard for the meter cops to inspect. On at least one occasion, as I was leaving my spot, and saw a new driver arrive and head toward the kiosk, I interrupted him and handed him my slip of paper showing an hour of time remaining. The concept of *selling* this time, especially in a city as packed as SF, is abhorrent.
Haven't you seen today's other headline? "Sony Warns Demand For Blu-Ray Diminishing Faster Than Expected" Streaming downloads are killing it off. My DVD collection is just fine quality for me. The only things I'm buying on Blu-Ray are epics that were originally filmed in 70mm, and for which my 120 Hz TV makes it possible to view in the original 24 fps (Blade Runner, 2001, Lawrence of Arabia).
The whole reason why you don't see the ignition in the dash anymore is because it was outlawed, I believe sometime around 1970 for cars (trucks and vans came later). The reason is that they considered it a safety issue to have a key sticking out of the dash where it could injure someone in an accident. Of course, you didn't have to put the ignition in the column, but that's what most manufacturers did . However, Saab is notable for putting the ignition in the console or between the seats in a lot of their cars.
Sure, carbs are easier to repair. I had to clean or repair mine, along with the points, every six months or so, in the first decade I drove a car. Since converting to fuel injection and electronic ignition, I've NEVER had to repair either in TWO decades of driving.
And it seems like the more scientific / theoretical the character's field is, the more antisocial they are. The closer they are to engineering, the more socially redeeming qualities and access to romantic partners they have. I mean, they made Sheldon downright asexual.
You're kidding, right? In what universe does asexual==antisocial? On that show, Howard (the engineer) is by far the creepiest character, mostly due to his (early season) sexually deviant behavior. In the circle of geeks where I live, his morality would make him FAR more antisocial than someone who is asexual. The show's writers really took creative liberties in making it that somehow he is the most "marriageable" of the main characters.
By they way, that circle is at the NASA Johnson Space Center. I have four very close male friends who are heterosexual, but confirmed bachelors at ages ranging from 40-55, and they are all quite sociable. Howard is by far the character that requires the most suspension of disbelief. If in the real world, you got to visit the ISS to participate in the installation of a piece of equipment you designed, most of us would have gone multiple times by now...
And Amazon wants to make every dime possible out of Comixology. Nobody else has mentioned it here, but in parallel with the new iOS version, the new release of the Android app disables the ability to pay for purchases using a Google Play account.
Actually, to me, most impressive of all was the fact that something *in my lifetime* actually has to account for both special and general relativity. I remember studying them in my college sophomore physics class and having the standard student complaint, "When am I ever going to need to use THIS?" (By the way Mrs Morton, I still have not diagrammed a sentence in real life).
Maybe they learned what they wanted to learn, and didn't "need" (in the first-world sense) the device any longer. I put a power meter on my bicycle. After about a year of riding and reading it, I could estimate from my perceived exertion just about what my power output was, so I removed the device.
Cars would probably be a lot safer if they were made more simply, and they didn't change the design ever 2 or 3 years. Stick with time tested designs and get all the bugs out and you'd end up with a car that was reliable and safe.
That is a strong assertion. Can you back that up? Over the years, cars have become safer both for the people inside and other road users (well, the latter probably doesn't really hold for SUV monsters), and also got much better fuel economy. A lot of that you can't achieve by debugging an existing design. Think of aerodynamics and crumple zones, which are integrated into the entire car design. Over here (Netherlands), the minimum age and frequency for mandatory technical inspections of old cars have been relaxed over the years, apparently because of the increase in durability.
The problem is the additional requirements/hardware, and the weight impacts. The 1989 Honda CRX HF had an EPA highway rating of 50 mpg. Today's CRZ is essentially that same form factor with "bugs worked out," but once you've added crumple zones, front and side impact airbags, ABS, traction control, the energy removed from the gasoline by substituting 10% ethanol, and whatever other requirements that have evolved, even a hybrid can only get 39. It would be interesting to see what a gas-only version of this car could do.
As an aside: We worked with CAA (Canadian version of AAA) and once every month or so we'd get a fax to unlock a vehicle (usually a Ford for some reason) who's keyless entry fob's battery had died. We would arrive and they are holding their key in their hand, pressing the button to unlock it and they are getting frustrated the vehicle isn't unlocking. I would calmly ask to see their key, walk up to the door and stick it in the door's keyway and turn it. The look on their face was always priceless. I even had one lady confess she didn't know that was even possible.
But if the car has an alarm system and it's active, this doesn't help much. If I unlock my car with a physical key, there's a three-step process I need to do in order to disable the alarm and engine kill. If your owners didn't realize their keys would work, what's the likelihood they'd then remember everything else required before driving away?

Has anybody smoked in space? You know it's going to come up at some point.
I remembered hearing something about smoking on Mir. This article was the fisrt I stumbled on when I just googled it.

Even more blatant, he was in the *same room* with his daughter and never got a clue.

yeah, bring back the small black patches you attach to your equipment to make it sound better, and oxygen free cables that only work in one direction.

Nope--I just sold my 1998 Honda CR-V. Ignition key slot in dash. http://images.gtcarlot.com/pic...

>I'm guessing the button cells for the 15C are a little easier to find.
15C takes the same A76 (LR44) batteries that my Minolta film SLR did. Made life easy.
Got my 15C as a Freshman in college in 1982, and it's sitting next to me right now. Just used it yesterday.
