So you do not care if people are unable to read the message that you are trying to communicate.

If you are too stupid to parse out some bad characters which obviously all replace the same character, you are not my target audience. You are probably unable to comprehend simple concepts anyway, let alone anything worth discussing on slashdot.

Here in Spain, wind turbines have destroyed many beautiful natural landscapes

Oh yeah? Did it build whole cities in them that the country doesn't need? That worked out really well for China, so you decided to take on the approach at home. But I'm pretty sure the wind turbines haven't leaned over and scraped away any massive patches of natural habitat.

I know you're making that out like it's a bad thing, but I actually think it's a good strategy to hold out as long as you can, because the more time passes, the more likely technology will catch up and make clean up slightly less difficult.

If we leave the mess lying around for a long time where it can be distributed into the atmosphere like at Fukushima if something goes wrong, you mean. What a great idea! Let's create lots of those messes and see if any of them blow up! Whoops, in fact, something like half our messes are exactly like that. Same reactor design, usually sited someplace ignorant where it will flood, with a bunch of spent fuel sitting around on top of it... sometimes more than they had at Fukushima Daiichi.

Your first sentience in your original post is fine. The rest of them make it very clear that you're not a programmer.

That was my whole fucking point. Congratulations on your reading comprehension skills, today. You get a gold star! I imagine you don't have too many gold star days. A programmer should be able to answer such a question immediately, even if the answer is "I don't have a favorite because..." and not just pulling something out of their ass.

"more distributed" means more land use.

No, not it does not. It means integrating them into existing land use, in places where they're not used.

human labor is an astoundingly costly input, even just from an environmental perspective.

Nonsense.

Modernization of food production is the central thing that has raised the standard of living from the stone age to the present day

Bullshit. That's often said but never backed up. The Green Revolution has in fact diminished our ability to produce food without massive energy expenditure. We must go back to a closed cycle in which the crap is reused or we will continue to deplete our topsoil. The best the GR achieved anywhere in the world was delaying starvation, and in some places it may well have caused at least as much as it postponed. Take a look at India to see what's coming for the rest of us.

Comment Re:Its just Apple being Apple (Score 0) 189

What kind of surprises me is that Apple doesn't have their own skunkworks R&D for coming up with new technologies like sapphire screens or other key components. They could work out what they wanted and then farm it out to someone who can mass produce it. Sort of like the Bell Labs or IBM labs.

Under Jobs, Apple followed Jobs' vision. Without Jobs, Apple has no vision.

Probably they should have gone with JLG and BeOS instead.

I'm pretty sure he's dead.

So you can agree that being raised by his own parents didn't work out so well, right? He destroyed his face out of low self-esteem in spite of being one of the best-loved entertainers in history, and died of a prescription drug overdose. Now, can you prove that being raised by someone else wouldn't have been better for him?

Comment Re:trillions of bits, why one head per platter? (Score 2) 215

Alignment isn't an issue - there's no alignment on a modern drive. Instead, at the factory, they write a set of servo tracks all over the platters which do the aligning for you - basically the head seeks to approximately the right position and starts reading, and the servo track tells it where it actually is, so feedback gets the head to the right track.

Sigh. Alignment is an issue, because each platter has its own alignment. That means that when you're reading/writing one platter, you're not aligned for the other platters. That's why you can't have multiple heads on one armature (which has multiple arms, all fixed together) and read/write multiple platters at once.

the bigger reason why two actuators didn't work is far simpler - think multiprocess programming. Both actuators could read or write data to the platters (of which there was one set) and if you screwed up the order of the accesses, you could easily write the wrong thing

You're being ridiculous. That's true no matter how many actuators you have — if you screw up, you write the wrong thing. Even if you only have one actuator, if you write the data to the wrong sectors, you're gonna have a bad time. But both actuators have the same job: write some data to someplace. The two don't have the job to write the same data. If the drive gets a command to write data to a sector to which it already has cached data waiting to write, then hopefully it just throws away the first command anyway. This is something we would hope any drive with queuing would do whether it has 1 actuator or a dozen.

think you do a read then a write of a sector - and the sector happens to be under the actuator doing the write

HDD sectors are either 512 bytes or 4kb. In the former case they are often smaller than filesystem blocks and there is no need to read them before writing. You just run right over them. In the latter case, they are typically the same size as filesystem blocks (we use bigger blocks on larger filesystems, and we use 4k blocks on multi-TB drives) and again, there is no need to read them before wrtiting. You only have to find them, which means waiting the seek and then for some fraction of the time it takes the spindle to go around once. Then you can write. This is true no matter how many armatures are reading/writing the same disk.

It would have been more interesting to have more of the responses from the scientists that work there rather than some droid in the marketing department.

I think that will have done them more damage here than good, by far. What's funny is that really nobody wants to hear a line of bullshit any more. Kawasaki just sent a clueless flack to be on Leno's Garage and show off their new bike and a good portion of the comments were about what a lame he was. That's at least half of what people will take away from the experience. Send someone who knows what they're talking about and can handle being on camera, or don't send anyone at all. Just send the bike and a brochure.
