Danfoss delivers air-to-water heat pumps to Greenland. Admittedly they switch off the heat pump function at -20C (-4F), but that still keeps homes there going for 11 months a year.
If the temperature is below -20C for a lot of the year, you can often put pipes in the ground or in a nearby body of water. Greenland is difficult though, because it's really hard to dig there and ice tends to destroy anything you put in the water. Therefore they're stuck with air-to-water.
If your electricity comes from a nuclear reactor, hydroelectric dam, or garbage incinerator, why not use it for heating?
Because you can do 3 times better really cheaply with an air-to-air heat pump. Gas isn't an alternative anymore, it's way too precious to just burn for heat.
If computing a collision takes on the order of 2^128 attempts, it won't happen. Anyway, you can make a collision of a 128-bit hash in 2^64 attempts, but even that is out of the reach for most people. Unfortunately you can generate collisions for MD5 much much faster than 2^64 operations.
Obviously antivirus software isn't going to blow an electrical fuse.
Actually that was the one I found most credible. Antivirus setting the automatic wakeup to turn the computer on at a specific time, and that causing the blown fuses. Obviously anything else turning the computer on at that particular time would cause the same result, and the electrical system (or the power supply) would have to be fairly broken in the first place.
You probably want to turn directory indexing on. This is the default for newer versions of mkfs.ext3, but you have to switch it manually for older installations.
Every time that I enter our printer room, I am amazed that a rubber boat full of Greenpeace protesters is not there; we seem to go through paper like nobody's business.
Possibly because the paper industry isn't all that bad. It isn't like we cut down Amazon forest for newspapers. Nasty chemicals are involved in the production of paper, but those chemicals don't have to escape or get near humans. If we use less paper, the forests might get cut down permanently so the land can be used for other purposes.
If nothing else, the technical challenges of transferring that energy from space down through a thick atmosphere to the surface of the Earth should warrant a discussion of just moving us all closer to the source in the first place.
Moving a significant fraction of the Earth population into space isn't going to happen unless we find a way to get essentially unlimited energy on Earth. And if there's plenty of energy on Earth, why move more than a few colonists?
And as far as more cows using fewer resources goes, you run up against basic physics. Calories in >= calories out.
Doesn't matter. The efficiency in producing the energy for "calories in" goes up as well.
Efficiency improvement is constrained by the universe.
Sure, eventually it is, but we are so many orders of magnitude away from that limit that it is of no practical concern for now. The universe doesn't force us to get milk from cows; improved technology could make it possible to synthesize it directly or to just have the milk glands without the rest of the cow. We may choose to not pursue those possibilities, but you can't blame the universe for that.
Why the hell does a bank need an ad campaign ? Why is it spending what is supposed to be our money on self-promotion ?
Is it not your money that McDonalds spends on ad campaigns? Or the money that Shell spends? Why are banks different than other businesses when it comes to advertising?
Well I don't know about you, but I'm pretty sure them cows don't produce 3% more milk with each passing year, nor do they yield 3% more meat. You can say what you want about wealth, but there is a fixed amount of natural, life-sustaining resources in the world, and printing more money isn't going to change that.
Wrong. The cows do, in fact, produce more milk every year (not the individual cow, but the average cow). More importantly the dairy industry becomes more efficient every year, making it possible to have more cows using fewer resources. Farming is a bad example though, as efficiency growths in farming in industrialised countries is lower than efficiency growth in many other industries.

64-Bit Java For Linux

It's not easy to find things that stop working with new Java releases. Those must be very crappy applications.
Of the things I need Java for, the only thing that survives Java 6 is Puzzle Pirates.
It sucks to have to bring in 32-bit glibc and all the other libraries just because a couple of stupid companies are living in the past. Welcome to 1992, Sun!
While it is true that Microsoft did all they could to kill Java, it is also true that Sun's Java implementation is ridiculously slow-starting and full of bugs.
Also, Java pretends to be compatible with itself, but it isn't. When you make a new interpreter, you either a) make sure newer versions are perfectly backwards compatible (by far the best option) or b) make them completely incompatible and force parallel installs. Sun pretended to pick a) but actually picked b), but they failed to provide for parallel installs of the browser plugin. Microsoft picked b) for.Net, which may be a lousy solution, but at least it works.
You are correct that the US does not over-produce but it is not at the EXPENSE of the rest of the world, it is to its benefit. Pick any US industry, and you will see this is the case. They are all either dead or dying.
So the rest of the world should be happy to build the corporate jets, while the Americans take on the hard work of actually lounging in the sofas onboard...
Not that it's like that, of course, 90% of the Americans are getting screwed too.
It was actually a flame, not flamebait, but Slashdot lacks a -1 flame. And the grandparent deserved it.
I don't follow the financial world much, so all of a sudden I see * industry bailouts over and over again... From an outsider's perspective, it kinda seems like a bandwagon [..] I wish politicians, CEOs, and just the general public would start looking at the long term costs and benefits rather than focusing on immediate reward.
To paraphrase: So yeah, I, uh, don't really know anything about anything, but I think it would be cool, you know, if the people in charge, like, could get together, and, I guess, do something I think is smart!
I really wish that distributions would start doing that when the user tries to install a 32-bit distribution on a 64-bit capable machine. It's easy to accomplish in Fedora after the fact; just force the installation of the 64-bit kernel. Still, it would be nice if it was done automatically.
The alternative is to teach users that they want the 64-bit version. Everything is ported. The problems are solved. There is no point to 32-bit anymore, unless you have an old machine like the one I'm writing this on.
I predict that the single biggest improvement the 64-bit OS will bring to the desktop is editing one's home movies.
What is the point of making predictions about a 64-bit transition which already happened?
Slashdot Mirror
Oh, and why on earth would a SD card manufacturer need to license a filesystem in the first place? It's not like it'll care what data is on there.
You can kill some SD-cards and USB-sticks by dd if=/dev/zero of=/dev/sdcard. They die if they can't find a partition table and a FAT file system.
Yes yes I know SI units are _supposed_ to be base-2 when referring to storage
SI isn't base-2. The HDD manufacturers are right, most geeks are wrong.
kilo was defined in 1795. HDD manufacturers switched from the incorrect definitions to the correct ones.
How about Frontmotions MSI packages?

but in the winter if you are running an electrical heater anyways
If you're running an electrical heater you've already lost. That should be banned (already is, in many places).

Note that the story says 5 hex values, not 5 hex digits. As in, this is one hex value: 0x1F.

You could also switch to ext4, of course.

We had almost unlimited energy, didn't we?
Not the kind of unlimited that would enable us to send even one million people into space.
