You should know that we'll do both, dump all the carbon we can gather into the atmosphere AND have a few nuclear accidents in this century. I consider ourselves luck if we get out without any proposital nuclear detonation.
"Chernobyl and Fukishama have now both shown that nuclear incidents are ALWAYS worse then estimated and even worse then admitted to afterwards by the nuclear lobby."
If that is the problem, we just need a few more accidents, to learn how to estimate nuclear accidents. Anyway, hydro doesn't have a good track record on estimations either.
Anyway, both nuclear an hydro are a nuisance when comared to the chemical industry in terms of deaths and lost terrain.
Even when you do have the bandwidth, how is it done?
Do they send clear text to the cloud? That's a big failure here. Do they send encrypted text? Where do they keep the keys? At the cloud? If they have a safe place for keeping the key, why can't they keep the backups there? The place is only fit for a pen-drive? Last time I looked, one needed large protections to keep fire out, why one would put those large protections around such a small volume?
I've already said that somewhere up from here, but...
After you spend the biggest part of the night doing the backup, it is not realistic to expect one to test it. You'll need to invest several men-hours into that test (while the backup is automatic), you'll need to keep your backup online and in house for long, increasing vunerability windows, and you'll create another failure point. Testing tapes is hard, you may forget about several restauration cases that are the ones you'll need later (reducing confidence of management that those several men-hours are well spent), and testing them just after the backup doesn't guarantee they'll work when needed (also doesn't guarantee you have no storage problem destroying all your tapes), so you need to test them often, further increasing the problems of testing I pointed earlier.
Backing up do disks is way easier, and rotating the disks will make problems surface earlier than with tapes. But disks aren't yet fit for a lot of data...
Well, there are a couple of things you didn't get into account...
1 - Laptop disks are made for transport. In fact, desktop disks are also made for transport (they must get on that desk somehow), but a bit less relaiable. The fact that they can stand less acceleration than a tape doesn't mean that you can't put them on a car (or carefully wrapped on a truck), and carry them aray.
2 - Who talked about inserting and removing the drivers into the slots? You backup to internal disks connected through USB cases. That makes the backup slower, but if speed is so big a problem you are on tape already.
3 - Tapes don't "show" they have problems. In places where people tests their backup frequently, it is not an issue, but on real places it is. Anyway, if it takes the greatest part of a night just to make the backups, do you increase the vunerability windows (and spend the needed time) to test your backups or do you take them ofline already? You can't backup to a failed disk, but you can backup to a failed tape without problem.
Due to all those, in real life tapes aren't as reliable as disks. They may be faster, and cheaper, but are in fact less reliable.
If I remember it correctly, the neutrinos should arrive years, not months before the light. That can be explained by the fact that we just weren't looking years before the fact. I know, it is a quite weard explanation, for that to be true the neutrinos should travel on just this speed, not a lower one, but we do have weard data to fit.
That second experiment from Opera, with the short bursts just takes away all simple explanations for the result. We have now just the possiblity they corrected some delay wrong (they forgetting to correct something isn't a viable explanation), or that the neutrinos are faster than light.
Ok, and mine is that the boss bosses (be them shareholders or executives) think about him as a gear in a box too, and try to take any signal of personality out of his job so that they can measure his perfomance with simplistic metrics and replace him at will.
Your boss is subject to the same conditions he is trying to impose on you. That is why he can't make a decision, and must do everything following a process.
Unfortunately, I've had that experience. He didn't survive being my boss for long, but it is a bad place to be.
Anyway, I don't get what gave you the impression that I was talking about not documentating things. I just said that bad bosses rely on irrelevant metrics because it both makes them feel better professionals and helps hide their incompetence from the upper levels.
No doubt you can measure quality of code or the competency of a programmer. But can you stablish an objective metric with fast results (remember, corportations are "this quarter" oriented) that gets it right?
"More and more, I think no one even understands the value of having a knowledgeable person make difficult decisions based on well thought-out judgments. People want procedures that they can just give to anyone and assume that the outcome will be the same..."
Don't you see several complaints around here that managers treat developers as gears in a box or stuff like that? Do you really think that is restricted to tecnicians?
Yes, they are objective and quantitative. Managers love that, because being objective excuses them from forming the kind of bias people used to call "leadership", and being quantitative they fit into nice formulas where they can convey no information at all to higher managers that are too insecure to ask what it means.
Just don't expect those quantitative and objective metrics to be correlated with the overall profit of your business.
It's not that simple. Yeah, some electricity will run through the insulating air, but not a lightining. Lightininh only happens when the potential becomes so big that part of the air ionizes, and starts conducting better. And theoretically, the ionization will happen in the volume between the charges, it doesn't matter what is around it. The size of the sky isn't really relevant, or at least shouldn't be.
Rectifying a signal that is able to jump over 200' of air?! Have they started to gather funds for the wold's largest pair of diodes?
Theoretically, you could do that with 250V diodes... I'd put them on a serial/parallel mesh for dealing with some of them burning, but putting diodes in paralel isn't that easy.
Wrong singularity. I find it disturbing when people talk as if something like that never happened before. Or people that dismiss it, saying that something like that can't happen to menkind.
Of course, the ones that already happened we can understand, but go ask a pre-industrial non-alphabetized peasant what he thinks about the scientific-industrial world...

What a great opportunity to let them know!
But I agree, shutting down is a bit too extreme. But why are they anouncing in a newspaper and not on their sites?

Yes, the 100% of nuclear plants seem to release less radioactivity than the coal plants. But you know, statistics on both are hightly unreliable...

Look at rdiff-backup.

rdiff-backup --remove-older-than 3M #Or something like that, man is your friend.
Then you'll have 3 months to correct your first line. I guess you'll do it after the first test, or never, but you'll lose all rights to complain.
Deleted a verb? What is that woosh sound, by the way?

That is for a kinetic payoff (just dropping stuff from the satelite). I can't even imagine how do you fire any other thing?
Then you'd see a city sized crater, not an exploded buiding.

A calendar (at least the kind you describes) measures time too.
You can only see the contract after you have paid for it, and there is no clear procedure to get you money back.
If that is not draconian, what is it? It doesn't matter what the contract says.
No doubt you can measure quality of code or the competency of a programmer. But can you stablish an objective metric with fast results (remember, corportations are "this quarter" oriented) that gets it right?
I guess you were never assinged that kind of job.

Unfortuinately, patent trolls come from the ash of burned money.
You find yourself surrounded by patent trolls created by your own action.

Or maybe his point was that, if Android was really open such things would be easy to fix.
