Comment Re:Cool world (Score 4, Informative) 216

This instantly reminded me of an 80's movie called Runaway with Tom Selleck, who is a part of a special task force to hunt down and destroy malfunctioning "runaway" robots.

Their handguns could lock on a target and program the bullets just before firing to stay on their target, although they looked more like miniature rocket based missiles with their own tiny engines and guidance fins.

I remember a number of the larger scenes giving a bullet-point-of-view type thing as the target goes running away and try to evade the shots by going around corners and obstacles, even purposely missing other people, before embedding into their target and exploding.

The above link has a picture of the bullet from this movie, and even goes on about a real prototype from Sandia National Laboratories back in 2012

I wonder how much these two groups worked together on these.

The entire Industrial Revolution in the States was because people stole "intellectual property" from England. Samuel Slater, and the rest of the gang up and down the Blackstone River got all their tech from England.

And it's hailed as an achievement here in the US.

Somehow it's bad when someone else does it.

>Calling the F35 good technology

No, no it is not. It is a boat anchor. A very very expensive boat anchor. It's the exact same thing that happened with the F111 at the demands of Robert McNamara but /worse/. A jack-of-all-trades-master-of-none-but-with-vtol and maintenance nightmares.

All it takes is that the parents of such an asshole student are "important" because they donate money into the school's coffers, basically buying their precious little dud a degree.

And when told that you can't fail those students and kick them out of your class, you do what anyone clever would do, and bring some light to the problem by failing the entire class. Bravo! Goddamned brilliant, if you have integrity and are willing to deal with the consequences that is.

Actually...sad.

These might just have really *BEEN* some of the coming entitlement generation kids, the same ones that always got a trophy growing up just for showing up at a game or whatever.

Maybe they all did deserve to fail?? I hope they at least have to take the class over and aren't all given automatic passing grades whether they deserve it or not...?

Comment It depends where I am (Score 1) 301

One of the primary uses for my laptop is as an audio workstation. If I'm at home I connect an external keyboard and mouse directly to 2 of the ports. The third port connects to a powered hub that connects a 61-key synth, a 25-key midi controller, a contoller pad, an external track controller, an audio interface, and a secondary audio interface that allows me to use tablets and smartphones as additional controllers/input devices. And a large external backup drive that I don't leave connected all the time.

Grand total of 10 devices if you include the usb hub itself as a device. 12 devices if you include a tablet and phone connected to the special interface.

On the road I'll just plug in a mouse and maybe the 25-key controller if I want to do any music work at the hotel as a break from the grind. My actual job is in security, the music is a very serious hobby.

I couldn't find a better map, but fluoride can always be found in meaningful amounts naturally in groundwater.

I use a RO filter, you insensitive clod! I don't even care what's in my water, unless it's so severe I can't bathe in it. And I use a spin-down filter, a spun filter, and a carbon filter before that happens anyway.

It's sad that you need to filter your municipal drinking water before you can drink it, though, especially when that's in part because they added nasty crap to it.

Comment Re:The grid needs storage - not battery storage (Score 1) 334

As to your used battery idea, it is not a good one. Most used batteries are car batteries.

Aside from the fact that we're talking about used EV batteries, it might interest you to know that high-end vehicles are now replacing their flooded lead-acid starter batteries with Li-Ion packs. Even a really dinky one is capable of starting the vehicle, but the truth is that there's embarrassingly more electrical accessories in the modern car, and they need a battery with more capacity so that you can use them all at once even in a vehicle with a stop-start system. As the price on electrically-operated accessories (like power steering, heat pumps, and so on) comes down due to economies of scale, you can expect this trend to proliferate down to cheaper cars. It's pretty hilarious to look even into older vehicles, say a saturn, and compare the size of the battery to the size of the engine. Which block is bigger, the battery box or the cylinder block? A Li-Ion battery would be half the size, and let you design a foot off the length of the vehicle — or put it someplace else, where it would do you more good.

Anyway, these Li-Ion packs can be broken down and their individual cells tested, matched, and re-used, so the car starter battery of the future will also be useful for these systems... just not the batteries of today. Those are already aggressively recycled, however, like most car parts.

I've also used a slightly amount of hyperbole, they won't cost $0. Packs will at minimum have to be tested and recertified, and in many cases will need cells replaced — and individual cells will need to be tested and matched into groups of cells with similar characteristics for maximum output. That all costs some money. However, it costs nowhere near as much as putting the packs together in the first place; it costs some charge and discharge cycles, but there's no reason why these cycles can't be performed as part of an actual operating load-smoothing plant. After all, you'll have many modules in parallel, and any which cause you problems will simply be removed from the system. On the other hand, some packs might well be usable without any cell replacement, and they really would cost only the transportation costs and testing logistics and overhead, less the profit from their participation in load balancing during testing.

Those who are more paranoid acknowledge that ownership problem and do updates using an alternate method, i.e. login.

I don't think you understand what I said. If you've only got one uid, then both your web user and your shell user are the same user. This is typical of low-cost hosting services. Unless you're colocating, you've typically only got one uid. This ain't the law, some providers will let you crank them out, especially if you're chroot'd.
