Most locks aren't. Some locks are, for when you've got a big building and don't want to have the security guards lugging around 100kg of metal.
It's done by installing master wafers into the lock. A normal cylinder lock has pairs of pins, touching each other with a spring pushing them into the hole where you put the key. When you put the key in, the pins all line up, and the cylinder can turn, opening the lock. The length of each pin varies, in the same pattern that you see on the key. By putting in master waters you instead have 3 pins, meaning that each set has two possible positions, and therefore two different keys work in the same lock. By making the second key the same in every lock, you have a master key. The master key for each building or complex would be different, so there is no universal master key.
Adding master wafers increases the cost of the lock, so it's only done when the lock is going to be used in a master key situation.
There was one patent on the original AT&T unix, and that was over setuid mechanism, #4,135,240. At that time software patents were explictly not allowed, and therefore the whole patented mechanism is described in mechanical terms. This patent has of course now expired.
gazeteer/map that will allow you to make sense of the UTM or lat/long coordinates and/or any small visual clues you get from your consumer grade GPS...
It wasn't a problem. The GPS gives me a map which gave me my local position, which I could find on my paper map. The GPS was better for locating where I was, while the paper maps were better for long term planning.
The NANP area has been fixed on the 3+3+4 pattern since 1947. Some areas took a while to get to the standard 3+4 digits, but no-area has exceeded it.
In order to break out of the 3+3+4 pattern would require a huge conversion for a lot of equipment which assumes that's how phone numbers are formatted, both that owned by the telecoms, and also that owned by everyone else. Therefore, it doesn't make sense to do it until the entire NANP is nearing exhaustion, which is several years off.
The higher end Garmin units have 24 megs of map memory. The memory used for the trails, waypoints, routes etc isn't counted in that 24 megs. That's why the low end units have 0 megs of map memory, but still have the same number of waypoints etc. Also not counted is the flash memory used for the software.
If they wrote it without TPM then it would be hacked, so TPM is pretty much a pre-requisite.
The opposite is also true, if they wrote it with TPM then it can still be hacked. If the object files for the DRM program are distributed on any non-trusted medium, for example the internet or CD-ROM, then they can be read on a non-TPM system, and attacked. It expect it won't be easy, I'd start with a TPM protected decyrption program, but non-easy and impossible are two different situations.
If I'm looking to buy a device, I'm going to be most interetested in it's hardware compability in free OS's. Anything which makes it harder for me to buy a PCI device which works is going to make me less likely to buy a PCI device and instead use an alternative.
I've got a plethora of networks to hound for one file, depending on who has it. With my mac, I'll only have one, and if the file is out there, it's on that network.
I'd still call that a bad thing. I like diversity. It allows a much better match between my desires and what's provided.
Wouldn't bugzilla and other similar bug tracking systems fit into this? If you read some code and think that it needs attention, you raise a bug, and this will either track it until it's fixed, or record a reason why it doesn't need fixing.
UK supermarkets, indeed all supermarkets, are there to sell bland lumps. Doesn't matter what the product, it's got to be sanitized and regularized to make shopping in June the same as shopping in December.
The numbers of farmers have gone down because agriculture has changed from a labour intensive industry to a highly mechanized industry. This allows a much smaller numerically industry to be equally good, or better, at generating money for the economey.
Yes you can. It's called a master key. You have to be a locksmith, or be really good at social engineering to get one.
Very few locks have master keys, in general only those which actually require them, for example in institutional buildings where the security guards need to access all the doors without carrying around 2000 keys. It costs money to install master wafers in locks, and no lock manufacter is going to do that unless they need to. If you take a typical lock apart you'll see for yourself that it doesn't havfe master wafers installed, so only one possible shear line, so no possibility of master keys.
And why do you think getting rid of stock is a bad thing?
The stockmarket has become nothing but an acceptable way to gamble. People don't invest in a company for dividents, they buy shares so that they can sell them later for a profit. It's also got a ticking timebomb in that the majority of the money comes from people's retirement funds. As the baby boomers retire, and want to get that money back, it's going to collapse anyway.

No, they've had to change their numbers because of the completely incompetent way that the UK numbering has been handled.
I don't think the power requirements of a few extra Mb of RAM will be much compared to the power requirements of a GPS unit.

I think you'll find the documentation on the process here/A.
You don't have to be a real expert, all you have to do is match the datum on the GPS with the one recorded on the map's title block.

Well that's a political issue, not a technical issue, and therefore would apply no matter what tools you use.

I think it's becoming a rule that the DMCA is used whenever the original company does something really stupid.

The collections include a tiny fraction of the culture we create. For example, it's estimated that there are 80 billion new images each year.
As for IE's load time, it appears to load instantly because it's real load is shifted to the boot sequence.
