You could also probably build the powered devices to run off 12V for less than what this inverter would cost.

Lower voltage, higher amperage required for same power, rapidly increasing power loss with increasing wire length, even at residential scale. There's a reason that your power supply for your 12V lights goes close to the lights and you don't run 12V through your house.

netflix listened to customer feedback when they tried to spin off their disc rentals to another company. so call them and give them feedback. they are easy to reach by phone. if you dont complain to them please dont whine on slashdot

The difference here is that very very few people will care. We're talking about mailing in a DVD on Friday, and getting the next on Tuesday instead of Monday.

Most of us have jobs and lives during the week. Most DVD watching is concentrated to Fri/Sat/Sun.

Apple failed to mention the bit about, if a US government agency had contacted them and requested information or for a backdoor to be put into their device, they'd be required by federal law to lie about it or face charges of treason.

That's not true. They could keep quiet; there is nothing in the current (unconstitutional) laws by which they can be required to make any statement at all.

Wouldn't a standard pressure cooker set to sea level pressure solve this problem?

Pressure cookers help, a lot. But they're not "set to sea level pressure", they are set to a differential pressure of whatever the current pressure is + some fixed PSI. (Or, in the case of the one I use at home, your choice of 2 pressure offsets.) So you need either experience or some mental juggling to estimate cooking times with one.

So, yes, depending on your altitude, they can help a lot, or make it just like cooking at sea level, or make it faster. And they do make lightweight portable ones for camping. But "lightweight" and "portable" are relative. You would NOT schlep one of these along for a solo backpack trip. But if you have any kind of vehicle, or porters, supporting a more heavily-equipped trip, then it's certainly an option.

Ok, how about: "it boils colder, making cooking slower"? Because that's what mountaineers and other people at high altitude complain; e.g., pasta takes forever to cook properly (whatever they mean by it), resulting in a goopy consistency.

That part is completely true, and not what I was disagreeing with. At 10,000' cooking dried pasta is tricky. But at some altitude, it actually becomes impossible, because it takes 186F to even cook at all... Same with many other foods, cooking by boiling gets slower & slower, and eventually altogether impossible.

A liquid boils when it reaches the temperature at which the partial pressure of its vapor equals the external pressure. Higher altitude means lower external pressure which means water boils at a lower temperature at high altitude which means a pot of water boils faster, but food cooks more slowly.

No, I don't believe it boils faster. Granted, as you correctly explain, it takes less energy to boil water at high altitude, but there's other factors you're leaving out, for instance, the big one I know about: efficiency of combustion. So while it takes less energy to boil that water, guess what you're getting from your stove? A lot less energy...

Not to me it doesn't. The point that I was making is that it is useless going after false DMCA claims for perjury because the only tiny bit of the notice that is under penalty of perjury is not the bit that is wrong in false claims.

Ah, now I see where the confusion is. The thing is that you're wrong, because *MANY* of the stories about false claims on /. are about claims made by companies who do not have any rights whatsoever in the allegedly infringing work, including this story. Going after perjury charges for companies that make claims on works in which they have no rights would be a damn good start.

Switching power supplies actually provide decent protection against moderate surges. You want to find things damaged by this kind of incident? You'd want to check claims for all the things in your house that contain *motors* which run on line voltage: washer, dryer, refrigerator, freezer, dishwasher, etc. Your computer etc can take an extra 50 volts basically forever, but motors cannot. (Also, heating elements will tend to burn out. An extra 20 volts will make your wife go through blow dryers at a prodigious rate--it's true, you can take my personal word for that!)

If money can't buy happiness, I guess you'll just have to rent it.
