"Let's start with MySQL. We back up our database daily using Zmanda. A few months ago, we had to restore it. It took THREE DAYS."
Well, I can't say exactly what happens to MySQL, since I've never restored a MySQL database, but it could be a problem with Zmanda. (Didn't try Zmanda either, as a rule I avoid products whose website yell "The lider in XYZ".)
"Suppose your server has about 100 gigabytes of data on the hard drive, 95% of which is related to your application. Tar it, download the tarball, and you've just burned through half of what Comcast will let you download for the entire month."
That is why you do differential backups (on disk you just need a complete backup once, ever), and use the rsync protocol to get the files over the network.
If your service has new 100's of gigabytes every month, you should think about hosting it at your place.
If you are backing it up to disk, take a look at rdiff-backup. It is quite similar to rsync, but creates a versioned backup so it won't propagate a corrupted database or deleted file to your backup (unless you tell it to do so).
Well, I'd say that when your current contract expires, you should look at somebody that offers both. Also, make sure you are not stuck at PHP... (Just a guess that you are using PHP here, but even if wrong, it applier to any language.)
There are plenty of providers that will offer you the most common options.
Huw much processing and redundancy would that same money buy at the inexpensive side of things? Most of the time, buying three times more hardware and software will get you a bigger capacity and bigger uptime for a smaller price.
Altough, some times it won't. But Oracle couldn't sustain itself on those few clients that really need top datacenters, even assuming Oracle does in fact fit into a top datacenter (what is quite iffy).
You only have yourself* to blame, for choosing a plan that won't give you options, when you should know you'd want them. Next time you switch providers get somebody that will help you instead of getting on your way.
* That "yourself", of course is corporationwise. That could mean your boss, or his boss, but it probably means you, because big corporations hardly use non-flexible hosting providers.
Yeah, people are simply unable to work by themselves. They must pay taxes, so that the government gives the money to big corporations to invest and command those taxpayers to work. Really, if we didn't just give our money to big corporations, they wouldn't command us to work, and we'd simply have no salary at all.
"I don't think it's unreasonable to require smoke detectors in homes (the total cost of smoke detectors is a tiny fraction of the cost of a house)"
"I've seen regulations put the companies of two of my friends entirely out of business - one was due to a conflict between state and federal laws that made it impossible for his company to pass a safety inspection with both the FDA and the state regulatory board."
Yet, you fail to notice that the most reasonable piece of regulation (like your first example) can turn into a monster if the circunstances aren't exactly right. I'm not against gevernment regulation either, but price isn't the only thing you must look. Legibility, tranparency, simplicity and lawer proofness (lawers can make use of most regulations to get completely different things than the legislators tought they'd get) are vital, and I'm yet to see a government body that cares about such things.
"So the competition does apply pressure on governments to not overregulate."
You should thank God that you don't live in a hightly corrupt society. Here at Brazil once the government puts its nose into some economic activity the big players all pressure for more regulations (that apply to small players) and simply bribe their way out of the mess (or just don't comply with the regulations and get lawers to reduce the damage).
That is not a bad proposition. Open all the doors and let foreigners compete with brazilians on equal stands. The only problem is that the foreigners wouldn't allow that. They can't lose their competitivity.
I did a quite interesting tetris game at my assembly class by the time. Anyway, that is not software that I wrote all by myself, the assembler rewrote it all...
The last time I coded something all by myself, it was a test suite for a processor I was designing at a class. Talk about useless... Anyway, the processor was loaded into an FPGA by some software that I didn't write, and the design was compiled too.
There is (in GR) no configuration of gravitational fields that would allow a particle to travel faster than the speed of light. Gravitational fields can not decrease a distance, only increase it.
Now, I'm not saying that gravitational fields are irrelevant here. They can certainly influence the measuring equipment, making clocks differ or making people measure a bigger distance than in fact was. We'll only know with enough repetitions of the experiment...
Nope. With Lorentz transformations you can have just one speed that is independent of observer, and Maxell equations make the speed of light independent of observer.
Thus, the speed of the light is the only speed one can use to derive Relativity.
They found that their neutrinos travel faster than the speed of light in vacuum. They didn't measure the speed of light in any medium, they just measured the speed of neutrinos and got a value that was bigger than c.
There is no place you could use any refractive index to change the result.
"There's no reason a program can't have more than one management interface, and not be a chore to configure."
There is no reason to not make a GUI available for configuring some program. But there is a reason the GUI configuration is always slower (demand more time from the user) and less powerful than the CLI.
Also, most software that are a chore to configure come from the "the GUI must do everything" philosophy, not from the "let's make a nice CLI, somebody can add a GUI latter" one.
But he won't follow that advice, because he doesn't want to use a CLI, and altought all the stuff Ubuntu uses to avoid a CLI are available on Debian, they aren't installed by default. Or, in other words, because he doesn't want the essential, and wants brown lipstick smeared all over it.
I'd tell (hell, I'm already telling) that it is a mistake, and all those stuf he thinks will make his life easier will just stay there waiting for their turn to bite him, but as a good newby, he won't listen. So, the best advice is to get Ubuntu, so he can upgrade to some stable thing later, and avoid CentOS because altought it is way more stable than Ubuntu, the upgrade option is missing.
The difference between a server and a desktop kernel is the way all those questions you get when running "make menuconfig" are answered.
A few important (on my opinion) differences are the way the scheduler is optimized (to throuput instead of lantency) and the default stack size. In old times the desktop kernel normaly missed SMP, but those days are gone now.
That lazy IPv6 didn't even think hard enough to learn how to fit more than 4 billion addresses on 32 bits!
But, no. IPv6 didn't already won because it brings no improvement for most of the people we are expecting to adopt it. The history of the Internet is full of things being (mostly) replaced. By the way, what is your ICQ? And did you see the latest news at usenet?
And that actual situation is even worse, because those are two monopolies* closing an exclusivity deal. It doesn't seem bad to me, but it does deserve some investigation to stablish that as a fact.
Now, just to answer the GP, I also think MS sharing its profits with OEMs deserves some investigation, and on this case there is quite some smoke emanating from it.
* And if you don't consider Apple to have a monopoly on phones, they are doing an agreement with their only real competitor. That is even worse.

They'd aquire lots of expertize, contracts and good will.
Now, Oracle being Oracle, those would last for a week or less. But that is not because RedHat is worthless.

You say both of those:

Cobol, man. No way anybody would do that in assembly.

Or could that be because programmers don't know people that well. For lots of us, human factors are magic, and a very exoteric kind of it.
You can debug a computer, it just takes money and time. You can't debug a human being, at least yet.
They can't issue igNobel peace prizes, they would choose the same characters of the Nobel prize lots of times, and that wouldn't be good.

It is more like when Duke Nuken Forever was released, but that is not a car analogy...
So in other words, she did fing the methods or the ethics questionable.
