They do, they are called history lessons. We had to do the Industrial Revolution at school (history was a compulsory subject until we were around 14, IIRC). This isn't really any different from learning about the Industrial Revolution. I'm sure some schools taught agricultural history.
When I was 15, I had an accident (put my hand through a glass door, the glass cut through my wrist clean to the bone taking out all the tendons as well as the median nerve, that runs roughly up the middle of the front of the wrist and supplies the thumb, finger 2 and half of finger 3 and part of the palm with sensation).
To repair all the damage, it took 6.5 hours of microsurgery. The nerve took several months to fully regrow.
When it did, the sensation came out in all the wrong places - if I touched part of one finger, the sensation would come out somewhere else, for instance on another finger or somewhere more or less random in the affected area of the hand. But within a few months, the brain had "rerouted" everything, and the sensations gradually started coming out in the right place.
No seriously. We have monitors like that at work that have a stand that allow them to be turned on their sides to view or use "sheet like" programs like web browsers, word processors etc.
It's not just about the languages, it's also understanding fundamentally what's happening on the raw iron. I'd also suggest that assembler (any architecture - the 8 bit ones like Z80 or 6502 or perhaps a microcontroller ISA such as Atmel's AVR aren't a bad place to start because they are straightforward) is worth a good look over. If you've written functions in assembler, you grok at the fundamental level why buffer overruns are so bad, rather than just being told that it's bad. When you've watched an unchecked buffer write over the machine stack, it's a lot more powerful to learning this than "Segmentation fault (core dumped)". When you've had to figure out how to test a complex condition with many instructions, you get the idea why perhaps you should try not to have this in your inner loop. Etc.
And someone who has done even just a little assembly language has no problem with pointers, or the concept of passing by reference.
Wrong; I can think of at least one instance off the top of my head. Due to pilot error, a Boeing 707 landed in Lake Victoria, short of the runway it was supposed to land on. Not only was no one hurt, the aircraft floated for a while. Only the landing gear was torn off. There are pictures of this on the 'net.
If a large aircraft touches down in water with wings level and without an excessive rate of descent, you stand a reasonable chance of getting out of it alive.
I'd submit the defence system is still a bit of a waste of time: it won't do anything about unguided shoulder-fired missiles.
Airliners are likely to be targets when they are flying low and slow, such as approach. As such, they present an enormous target. It would require the shooter have skill, but given enough terrorists, sooner or later they will start scoring.
Then again, with security being such a slow moving queue in the airport these days, what's the bet the next suicide bomber will simply blow himself up inside the 400 person deep queue that's concertina'd in the terminal building waiting to go through security?
Where do you get that idea from? Other militaries adapted to this years ago. Radar guided missiles, wire-guided missiles and simple AA guns have been around for decades.
Most aircraft? That's a bit of a sweeping statement.
The world's most popular short/medium range airliner, the Boeing 737, has control cables (and hydraulic boost). It's entirely possible to control a 737 with no electricity and no hydraulics (only the rudder won't function).
All those little regional jets like the CRJ and ERJ are all cable controlled. The DC9 series (DC9, MD80, Boeing 717) don't even have hydraulic boost, it's pure old fashioned steel cable. Every bizjet you might meet - steel cables (or hydraulics for the big ones). Anything with propellers (all the short haul stuff) - steel cables.
While some (but not all, by a long way) new designs are fly by wire, most planes are fly by cable, cable and hydraulic boost, or hydraulics.
Incidentally, Concorde was the first fly by wire passenger jet.
Or the other way around. I find vast amounts of information are often easier to remember than phone numbers, especially if the information is interesting. So... how about "imagine if a phone number was as easy to remember as a vast amount of information":-)
It also has a fringe benefit of wide tracts of IP addressing space can't be easily just scanned for vulnerabilities by people hunting for a botnet. Scanning an entire ISP's address pool at the moment is easy, so trojans and worms can just go looking for holes to exploit. When each ISP is likely to have at least 64 bits of address space, hopefully sparsely filled, it will take a long time to scan it for machines to exploit.
It's neither new nor hard. My solar garden lighting has at least that performance and at least that many lamps (high brightness LEDs) and will go a week without direct sunlight (it'll probably do more, but I don't think we've had a stretch of bad weather that long). It has an 80w peak panel, and a standard lead acid battery as storage (just the one).
The "daylight measuring electronics" are bone simple, it's just a simple comparator chip (costing pennies) that compares a reference voltage (taken from the battery) against the solar panel output voltage. When the panel falls below a certain threshold, it turns the lights on.
Slightly OT rant, but of all the places I would have thought would have better sense not to run obnoxious advertising, it'd be Slashdot. But recently, we've had ads on Slashdot with sound (it took me a while to figure out which computer was making the sound of a door slamming), and now an HP/AMD ad that rolls out a large graphic on top of whatever you're trying to read. Normal banner ads on Slashdot are fine, and if it's for something interesting I'll click on it. Obnoxious ads are not - they push me to want to install ad-blocking software, and then everyone loses: I don't find out about potentially useful products, and Slashdot doesn't get any ad revenue from me.
Forget LCD monitors, generally they aren't in very harsh, scratchy conditions. I'd like to see this type of screen protection on mobile phones. Most scratch so ridiculously easily just in normal pocket conditions.
...last year, when Symantec flagged part of the Windows Server 2003 resource kit as a trojan. That one stayed in 'the wild' much longer, probably because the resource kit in particular wasn't a widely installed piece of software.
We've also had Norton 'false positive' on the Windows version of Oolite.
One of these days, a widely used, automatically updated virus scanner is going to detect something like KERNEL32 as malware and kill a whole lot of machines. Wasn't there a problem like this with the Chinese version of Windows earlier this year?
The author probably has enough brain cells to realise that since he's producing software for leechers, there's no chance he's going to get paid for his software. Let's face it, this software will mainly be used to download unauthorized copies of songs/movies - if the users are happy to violate copyright law and risk prosecution to avoid paying, they aren't going to pay someone who makes the software that enables them to violate copyright law.
So really, advertising is the only way he's going to get payment for his servers. The users certainly won't pay.
The reason why you don't see solar panel factories powered by their product is:
a) Grid power is currently an order of magnitude cheaper b) Solar power is intermittent, but a factory requires a reliable supply.
While a solar panel factory could be partially powered by its product and use grid power at night or when the weather is bad, (a) still holds true at the moment. If this new process really does get the cost to what they say it will, then I suspect every factory in the world will have a roof full of panels in time.

An anecdote about nerve re-routing...

Well, it is a dumb question - the TFA states that the attack used specific features of Microsoft SQL Server.
I was just surprised it wasn't yet another exploit in phpbb.
Turn the display on its side.

No, someone didn't set up shop next door: Intel effectively said "I'll help you set up your shop", as a ruse to stab them in the back.
They are called optoisolators and have existed for decades (essentially an LED and phototransistor pair in a small IC package).

Enemy Territory does know how to resolve names... just put the server you like in /etc/hosts or your local DNS server and you're done.
