If the garbage collector in your language doesn't work, or you're pushing the limits of the hardware, sure, you have to think about memory management no matter what language you're in. Like I said, it's knowledge that's worth having; it just doesn't have to be a prerequisite for basic algorithmic knowledge.
You stop referencing it, and next time you need more memory, the garbage collector notices and recycles it for you.
The particulars of memory management can be worth studying, but mastering them is not a prerequisite to understanding algorithms and data structures. Sometimes you care what happens to memory you're done with, sometimes you don't. A problem with non-garbage-collecting languages like C is that, whether or not you care, it's still your problem.
Is there any reason it has to be a network-level mode switch rather than just issuing emergency responders "cell phones" that get a higher priority all the time?
Temperature is average kinetic energy, not average speed. While speed (the magnitude of velocity, which also has a direction) is limited to c, kinetic energy increases without limit as speed approaches c (it's not ½ mv^2 anymore).
...it's operated both in field tests and tethered in a lab (when trying out things you're worried might not work), and it has to run on alternate power indoors because of fire codes.
If you keep the price low, you're not giving any more people access to it; you're just changing how you prioritize. Where a high price prioritizes rich people, a low price prioritizes idle people: those who can spare the time to wait in line...
...which, when you think of it, is precisely the target market.
This administration is neither the first nor the last one to use law enforcement officers to harrass the opposition. Practical freedom of the press is undermined when it is too hard to write anonymously.
You build a kernel that includes the two modules you need (network card and nfs) to get access to all the other modules. It's Not Hard. So all you need on the device itself is a bootloader and the core of the kernel.
Yes, the NSA's modifications to Linux are open and subject to peer review, and the US government is at least somewhat bound by the Constitution and doesn't usually round people up and execute them because of their politiccs, so it is probably reasonable to overcome one's paranoia and trust them despite the fact that they are a secretive government agency whose primary purpose is spying on electronic communications. The paranoia is there nonetheless.
Meanwhile, in the case of a closed-source product out of China, the mitigating factors I just mentioned are not there at all.
I tried to install Opera on this here Debian Opteron, but it won't run: I'm using 64-bit shared libraries, and they haven't compiled a version for x86-64 Linux (or anything, for that matter) yet.
Meanwhile, since Firefox has publicly available, portable source code, the nice people at Debian built it for me and packaged it neatly and I've been using it happily on this machine since I bought it last summer.
The term "firewall" includes any application-layer filtering they may be doing. For example, they might be running a transparent caching/censoring proxy.
People in the business of selling things called "firewalls" will, in fact, insist that mere packet filtering doesn't even deserve the name.
I don't actually block ads other than by turning off window-manipulation JavaScript functions. If a site has ads that annoy me, I go somewhere else. But the hosts file hack is a Slashdotnik shibboleth.
Spammers would have to look up everyone's keys and encrypt every piece of mail individually; and even worse for them, they'd have to send every piece of mail individually. The resources required to do this in the volume spammers currently spam would be tremendous, perhaps beyond even the reach of a large zombie network.
...but it is absurd to imagine that the rate at which errors are introduced is anything like the rate at which good information is introduced. The comment I was responding to postulated that it would converge to a mean, which would only happen if editing were totally indiscriminate.

Way to jump the gun.

Just sayin'.

Static magnetic levitation with permanent magnets is impossible. The globe works because it's spinning. Somehow that solution doesn't seem feasible for current laptops. Now, if you came up with a diamagnetic case, maybe...

Perhaps other factors are more significant in your case.

I have enough trouble trusting NSA-enhanced Linux. What are the chances this doesn't have nasty spyware and/or censorware built right in?

I can't believe you left out the rest of the headline.
The trust Google has comes from doing stuff like this zero times. One is not zero.
The whizzy Apple effects mostly happen in the whizzy graphics card.
