If you allow ssh access from the wide internet, and you have a weak password for root, you are probably still vulnerable.
If you allow ssh access from the wide internet, and you have a weak password for root, you always were vulnerable. Now the vulnerability is just being exploited in a more automated way.
If you RTFA you'll see that you're only vulnerable if you have a weak password. I guess the worm uses password guessing as the "exploit" to take over your router.
If they're going to mark you as leaving 'on bad terms', you may as well move the date up and quit now. It's not like they can do anything additional to screw you. Move on to your next (and presumably better) job and forget about the last one.
If they can't compel you to tell where the contraband is, just keep your secret key written on a piece of paper and hide the paper where they can't find it. They can't compel you to tell them where the paper is, and if the key is long enough, you can't be reasonably expected to remember it.
Why not just carry the larger device with the GPS and transmitter and forget about the injectable chip? Either way you get the same protection.
Unless of course you're relying on criminals being stupid in which case you might be able to convince them that the satellite can actually track the injectable chip.
The 1/(r^2) rule is the most important rule for electromagnetic radiation. If you hold your phone 2 inches from your head, you will get 1/4 the radiation you would get compared to holding it 1 inch from your head. This is why a headset drastically reduces radiation into your brain -- by moving the radiation source dozens of inches away from your head (although if you put the phone your pocket, you've just moved the radiation source a lot closer to your nuts). This also explains why your cellphone is absolutely harmless to the people around you, and why your monitor and speakers are not a threat, despite the fact that they emit a lot more radiation.
You can do it cheaply, but don't expect to get any amazing images. I have 4 cameras outside my house recording full motion video 24x7. I spent only about $800 on the hardware ($125 per camera, $50 per video capture board, and $25 for coax cable). I record at 640x480x30fps and I can store about 3.5 days worth of video on an old 120 GB hard drive.
I caught a kid breaking into my car at night, but there was no way to identify him, and police didn't want to pursue the case because he only took a few dollars out of my change tray. Even if his face had been clearer on the video I still doubt they would have done anything unless I also gave them a name and address. I believe the police view petty theft under a few thousand dollars as an issue for your insurance.
Your best bet is to install motion sensing lights outside your house. They're a lot cheaper than cameras and they have better deterrent value. If you still want cameras, get the lights too because they're much more effective than infrared-LED-based night vision, which have very limitted range.
After having these cameras running for more than a year the thing I use them most for is checking whether the UPS man left a package on my front steps.
Wrong. The definition of NP is the class of problems that a nondeterministic Turing machine can solve in polynomial time. P = NP if and only if a deterministic Turning machine can also solve those problems in polynomial time. A quantum computer is NOT a deterministic Turing machine, so P does not have to equal NP for quantum computers to solve NP problems fast.
The difference between a scripting language and a high level language is that scriping languages make it very easy to write small programs, but nearly impossible to write large programs. High level languages are the reverse. Perl can do very useful things in just 10 lines of code. However, nobody would want to deal with a Perl program 100,000 lines long. In C/C++/C#/Java it usually takes at least a few dozen lines to write even simple programs, but the tradeoff is that these languages scale nicely up to very large programs, with a million lines of code or more. I haven't written and Python or Ruby, but from what I've read about them I suspect that they are useful for relatively small to medium size programs -- which means they are scripting languages.
Can't you just write a iptables rule to drop RST packets destined for your bittorrent port? You could even get clever about it and drop RST packets that come out of the blue, but allow repeated RST packets to pass, so that connections that have really be reset on the far end can be closed.
Mod parent down. 480i is 480 lines, 30 times per second, or 240 lines, 60 times per second, depending on how you look at it. It is not 240 lines 30 times per second like the parent implies. Therefore, 480i gives 307,200 pixels, which is double what the parent claims. 1080p delivers about 7 times this many pixels, because 1080p is 30 frames per second, not 60. Technically, there are also 480i/30 and 1080p/60 standards, but the former is not used for TV broadcasts because it would look like shit, and the later is not used because it consumes too much bandwidth.
A better scheme would be to give out the same capcha to 2 or more users. If they agree on the answer, then there's a better chance that the text is correct.
I have a RAZR V3c, and Verizon's EVDO service, and I've have been plugging my notebook into my phone using a USB cable for months. The download speed are up to 2 Mbit/s and that's not exaggerating (you do need a strong signal, though).
I was 30 minutes late to my own wedding because I got trapped in a hotel elevator. The elevator was less than a month old. The hotel manager couldn't do anything to get us out, they had to call the elevator manufacturer to send over a maintenence man who only barely managed to force the doors open after breaking off the elevator key in the jammed lock. New elevators are scary!
Also, for all those unmarried geeks out there, I have a piece of advice: on your wedding day, take the stairs.
You've left one thing out of your math. Workers get older and gain experience. More experienced workers are worth more than fresh college grads (in some industries, at least). If experience matters in your industry, you should expect raises somewhat higher than the cost of living increases as you get older. The reason this doesn't cause runaway cost of living increases is that people eventually retire and are replaced by new college grads.
I would still argue that there exists an incentive to keep hosts relatively healthy to ensure that the virus spreads as far as possible and survives as long as possible. Viruses with no ill side effects or no detectable side effects at all tend to get less attention than viruses which make their hosts drop dead. Viruses which attract too much attention tend to get actively erradicated.
The other critical difference between biological viruses and electronic viruses is that, unlike biological viruses which rise out of random evolution, electronic viruses are still[1] created by intelligent designers who often have ulterior motives above and beyond maximizing survival of the virus. Electronic viruses are able to turn their hosts into zombies which the virus creator can enslave towards his own ends (usually some form of criminal financial gain).
[1] It's unclear whether we will ever see electronic viruses created by something other than humans. It seems unlikely to happen anytime soon, but if you believe in a future like Ghost In The Shell, then who knows!
You need to think about different types of hosts as different species of animals. Most viruses are not able to cross species boundaries. Also different memebers of a species may or may not be vulnerable to a virus due to variations in each one's immune system.
Regarding, the speed of speading, it's true that the initial spread of an electronic virus tends to be much faster than any biological virus. However, I would argue that there is a large population of hosts which are powered down (asleep) and/or unplugged (abstinent) 95% of time, as well as a constant stream of new hosts being created (born) into the world each day. It takes time to spread to the sleeping/abstinent hosts and the newborn hosts can provide an long stream of new victims, until a vaccine against the virus becomes widespread.
It should come as no surprise that computer viruses and worms tend to aim for control rather than destruction. This exactly parallels what happens with biological viruses and worms. A virus that destroys its host cannot propogate very far before becoming extinct. Viruses that damage their host but leave it good enough condition to continue transmitting it to other hosts are much more successful. The most successful viruses of all are those that go largely undetected and manage to spread to a majority of the population (think of sexually-transmitted diseases such as HPV).

Molten rock pushed back up the borehole several meters before solidifying, making it perfectly safe to study.

A corollary to this is never attribute to stupidity what can adequately explained by greed.
