You don't need to heat your house with electric radiators. Where I live, district heating is common and significantly cheaper than using electricity for heating purposes. My apartment uses district heating with the heat coming from woodchip-fired and waste-fired cogeneration plants.
In addition, it is much more efficient, at least compared to using thermally generated electricity from a non-cogenerating power plant, as those plants convert around 40% of energy input into electricity and cool away (i.e. waste) the rest.
Once a surge protector trips, its off until its manually reset.
Not necessarily. Many simple surge protectors just use a couple of varistors and gas discharge tubes connected between the wires. These devices have a variable resistance that is extremely high during normal operation but decreases sharply above a certain threshold voltage, and thus provide a short-circuit path for excess current to take. After the voltage returns to the rated level, the resistance again becomes extremely high, cutting off the short-circuit.
You are probably confusing surge protectors with circuit breakers. The latter are far too slow to protect sensitive electronics from damage from a voltage surge.
So how do you store it while in the aircraft? AFAIK, hydrogen needs to be compressed to a very high pressure, which requires heavy steel gas flasks for storage, not fuel tanks made of thin aluminium sheets as those used on aircraft today.
i think a single transcontinental flight takes more fuel than a car during the lifetime of its owner
That may be true, but using cars to transport the same amount of people the same distance would use more fuel at least if you count on only the driver (and no passengers) in each car. And with US-style cars, you could probably add two passengers in each car, and still have the 747 come out as the more efficient alternative.
A typical Boeing 747-400ER configuration has a maximum fuel capacity of 241140 liters of fuel, a maximum range (fully loaded) of 14205 km and a seating capacity of 416 passengers. This amounts to a fuel consumption of 0.04 liters of fuel per km per passenger, which translates to 59 passenger-miles per gallon of fuel.
Jet aircraft are insanely inefficient and guzzle fuel at prodigious rates
Actually not. If we e.g. take a common Boeing 737-400, with a fuel capacity of 23170 liters, a maximum range (fully loaded) of 4005 km and a seating capacity of 159 seats, it yields a fuel consumption of 0.036 liters of fuel per km per passenger, which translates to 65 passenger-miles per gallon of fuel.
That's not so bad, is it? Sure, it assumes that the aircraft uses its maximum range (take-off comprises a significant share of the total fuel consumption, so a short flight is much more wasteful than a long flight) and contain a full load of passengers, but still, it's a pretty good number.
One thing I've noticed is that the people who think they're the best drivers typically exceed the speed limit the most and tend to cause more accidents.
This reminds me of when I was on vacation in Greece in 1998, and rented a motorcycle for a day. The rental service representative told me that I'm not a good driver, since all good drivers are dead.
An H2 commands plenty of respect on the road (and off the road).
You wish. Around here, they are actually referred to as "penis enlargers" (direct translation), which imply that they are purchased by less well-equipped men to make up for their small frontal appendage.
This reminds me of another problem: Drivers unfamiliar with ABS should really try it under safe circumstances first, so that they won't be surprised by the vibrating feedback in the brake pedal. Otherwise, it isn't unthinkable that someone braking with ABS actually releases the brakes in surprise because of the vibration.
Have you realized that GPL enforcement and Windows license enforcement comes from the same thing as Copyright law?
There is one big difference though: Microsoft often comes after end users of its software, while GPL enforcement never concerns use. GPL enforcement is only directed at companies and organizations that distribute the code further without fulfilling the license obligations, specifically the requirement of source code availability.
Or, you simply block the signals that relays your position to the authorities, likely a built-in cell phone. Unlike in the movies, authorities cannot track pure GPS receivers, as they are only receivers, not transmitters. They need another unit to handle the data uplink, and that will use a common communication network, not GPS, since the satellites are primarily unidirectional, and since common GPS units are far too weak to send signals that far up.
Well, if cyclists think that passing just two feet away at high speed even though there is plenty of room is okay, they deserve to fall. Maybe they would learn something.
Every day somebody gets next to me and honks. Every week somebody rolls down his window and yells at me. Ever couple of months, somebody rolls down his windows and throws something at me.
I don't know about you, but most cyclists I see when I go to and from work would deserve such a treatment. I sometimes wish I had a stick that I could hold out just in front of them so they would fall. Why? Many cyclists are notoriously ignorant of the traffic regulations, and behave as if they own the road. They frequently run red lights, ignore pedestrian crossings (and yell at me when I attempt to cross in front of them), ignore one-way signs, etc, etc.
I use public transport for commuting, and I walk to and from the subway stations. As bicycling is pretty common and on the rise, I encounter cyclists pretty frequently while on foot in the city, and many of them are really annoying in their utter lack of respect for the traffic regulations. Motorists are actually far better at yielding to pedestrians than cyclists here.
May I humbly suggest that there are more than one or two slashdotters? There are many thousands of them, many with wildly different opinions. Is it so hard to imagine that there could very well be different subsets of the Slashdot crowd having different opinions on various matters? Then there would be no hypocrisy.
Slashdotters are not one uniform group of people, with one set of opinions. But of course, what can I really expect from a troll?
Or never knew it at all. I recently read that with SSL, you can use temporary anonymous keys for encryption, using the Diffie-Hellman key exchange, while using a normal RSA certificate for authentication. The user never knows the encryption key, so anonymous DH provides perfect forward secrecy, i.e. even if someone recorded all your encrypted traffic and later got access to your permanent key (e.g. by rubberhose cryptanalysis), they would be unable to recover the plaintext of the recorded traffic.
How can you be expected to hand over something you never had in the first place.
They can PAY a developer to do it. They are still the user. And, since the BSD allows the new developer to give the binary closed, the developer the user has paid can take the freedom to get someone else to do more work from the user who paid for it.
If you pay someone to write software, you can include a condition in the contract that voids the contract (i.e. you don't have to pay) if the developer refuses to hand over the source code licensed in an appropriately free manner, or any other clause to a similar effect.
I'm not sure how good an open source chip could get
That depends on what you mean. How good a chip designed by amateurs in their spare time could get is an open question, but there are open source chips that are pretty good.
I'm really thankful for this news. Just like Spore and Red Alert 3, I had planned to buy GTA IV at release, but I'll now enter it onto my no-buy-list. I simply won't buy any game that requires activation, installs irremovable crap on my computer, and/or can only be installed a limited number of times.
And I won't pirate it either.

Yes, yes and yes. SELinux is good because it lets you implement the principle of least privilege in a fine-grained fashion, which is especially nice for network-facing servers. And the policies aren't that hard to understand and customize.
IIRC, Red Hat doesn't actually mind people making and distributing RHEL rebuilds. People that are unwilling to pay for a support contract are not customers that Red Hat is interested in, so they don't mind them going to CentOS instead. It is also better than having them go to Ubuntu, because with a CentOS deployment, if they change their minds later on, migrating them to RHEL would be a piece of cake.

Just sounds a bit weird that always it is a GPL issue... never Free BSD/MIT/CC/etc.
What issues are people going to have with code that says that "you can do anything you want with it, as long as you keep this copyright notice"?

As programs got longer, they started requiring only the first 50 pages and the last page.
If your program consists of multiple source files, which ones contain the first 50 pages and which one contains the last page?
What happens if you "forget" the key?

Keep the core product closed and open up the extensions. Let the community improve your core product for free
How can the community improve your core product if it is closed source?
How many developers can continue to work for free in the present economic climate?
You sound like Andrew Keen. This has already been discussed to death in a previous thread.

People in general just don't care about DRM.
They may start to care when the game publisher screws them over from behind.
