There is a Google maps application that I know will run on SymbianOS that Nokia uses (s60 phones)... And on phones like the N80i, it even locates where you are with about 2 miles accuracy. It's a separate google app, doesn't need a browser.
So you take it out of rotation on the load balancer and give it a few minutes to complete all its active connections. Patch/reboot whatever. Bring it back into rotation, and repeat with the other box.
Methods like that usually suck in real-life, because right the day before you want to 'take it out of rotation', a circuit is opened through it that requires five nines (so you can't drop it), and it will remain open for months...
You will end up with 99 boxes waiting to 'get out of rotation' for every single box that you don't need to update...
Um, so a barrel of crude, unrefined oil, including delivery to Cushing, Oklahoma, is about $110 for 42 gallons. That $110/42=~$2.62 per gallon, and also still needs to be refined, really resulting in less than ~20 gallons of gasoline. Of course there are markets for the remaining ~22 gallons of 'stuff', but that $2/gallon raw cost for this 'cellulosic crude' doesn't look so bad at all at today's oil prices.
So either this stuff is already economically feasible, or current crude oil prices are unsustainable...
3D stacking of wafers with transistors is not the solution:
If someone were to try it, they better get working on methods to cool those stacks of wafers well, and ways to make the wafers cheaper...
If you make a chip with a stack of, say 10 wafers, you've also had to diffuse 10 wafers, costing, well, the same ten chips of only one wafer... Diffusing doesn't magically get cheaper when you stack the wafers afterwards. I'm sure the 'wafer-bonding' costs some dough too.
And it generates the heat of 10 chips of one wafer...
Now how much does a quad-core single-wafer chip currently dissipate? Isn't that in the range of 90-150 Watts?
Ten of those?
How many Watts does a maker use to boil a pot of water? How much a clothes-iron?
Doesn't look like a vulerability to me. So it can read files in/usr/lib/firefox, but those are just the standard files from the firefox package. User configuration and stored passwords etc are not stored there... It still can't get to $HOME/.mozilla...
Those can't be important for Intel (anymore): 8051 is a sub $1 microcontroller that, really, no OS runs on... and the XScale has been sold to Marvell in 2006...
When I turn on the new discussion system, I suddenly see a lot of '-1 troll' annoying posts. With the same settings and the 'old' system, it's nicely filtered as I want...
The whole pet-food-over-the-Internet thing had always baffled me, because I was curious to know if they really never realized that they wouldn't be able to use the Internet for shipping it to the customer. Attached to an email or something? But then again, it was the time when you could turn hot air into Venture Capital gold just by coughing the word 'Internet' in it. So, in that frame of reference, selling pet food over the Internet was a relatively good idea to pitch to the VC's... At the time, I really was curious to see how it would end up, and very happy to see that common sense returned... If selling pet food over the Internet would have worked as a business, I might have been forced to really start believing the universe was actually the result of less than a week of sweat from an Idiot Designer...
I don't think they actively thought of supporting DVRs, and I'm sure the companies involved didn't mind at all... You'll probably have to only record from one channel, or change the channel manually using the decoder's remote, etc etc... or buy a new vcr that can receive atsc (?)...
"Ideas could actually be lost, in cases where the inventor dies with his secret, which, of course, he'd be unable to share with anyone without endangering his livelihood."
First of all: Sure, nobody uses trade secrets today, eh? And second of all, an 'idea' is not worthy of a patent. If it were then I'd have a pile of patents every week.
With the quality of 99 out of every 100 patents being granted today, nobody would care if the 'idea' would forever be 'lost', because first of all those patents do not describe anything nobody else has already thought of, and second of all they are written in a language that only a patent lawyer can read (e.g. useless for everybody else).
Plus, solar panels can be installed much closer to the consumer, cutting a lot of the electricity transporation cost (and losses).
The table at http://en.wikipedia.org/wiki/Photovoltaics pretty clearly shows that $1/W, if the panels last 20 years, depending on the area where the panel is installed (how much sunlight it's getting), results in an energy cost of 4.2... 12.5 cents per KWh... So those panels will even beat a coal plan in Arizona, for sure...
Make sure to use one of the read versions for/dev/null, namely/dev/zero and/dev/random...;-)

From your description, it sound as if you found that the code returned different results at different optimization settings for the compiler, but did not pinpoint what instruction sequence exactly caused the difference.
Unless you were using an experimental compiler, that usually means a bug in the code, not a bug in the compiler. Run the code with valgrind, you'll probably find out-of-bound addressing, or uninitialized reads (the signs of the problem being in the code, not the compiler)... Or if you use threads, it can also be in your locks...
The reason for that is that such code bugs often result in different code execution at different compiler optimization settings.
The "Host" sections in the/etc/ssh/ssh_config file allows you to specify which port to use for each host you connect to (so you don't need to type "-p 1234" every time you connect).</i>
That config file can also be for each user separately in ~/.ssh/config , so you can do that anywhere you have a regular ssh account.
"Even if you do use it, you'd have to set the password then forget to reboot for it to be a problem."
Such as somebody with access to the terminal for 15 seconds when you're logged in and distracted (or a piece of spyware), and who would like to take the machine home overnight (after you think it's safely encrypted and turned off), to have plenty of time to secretly copy the whole 250GB of valuable data off it?
It's an opportunity for privilege escalation from temporary access to some time in the future...
And I understand that the 'feature' (aka BUG) is hidden from many of its users...
So it takes a piece of spyware only a fraction of a second to turn it on... So that when, as carefully planned, the actual hardware is physically stolen the next night during a breakin, the thief can boot the machine up at home and access all the data without restrictions... poof security.
Walks like a backdoor, talks like a backdoor... It doesn't matter that the door isn't open by default. In security software, you don't want backdoors.

Of course... It's not like google offers special special services for exactly that", either free or paid...
Perhaps you should start a telecom carrier company. Apparently you know easier ways to reach high reliability than the people in the industry today.

So, you really have a 5Mbit plan with a 20Mbit burst allowance.
I don't know what you're smoking, but.... I'd like to see a working prototype ;-)
