Though really, why not use "H3y Jud3, d0n't m4k3 11 b4d"? It has almost all of that, plus a good length.
Because the user doesn't control the hashing algorithm used for passwords. If you do that on a typical Unix box with good old DES crypt, the hash is only on the first eight characters, and your password is no different from "H3y Jud3". And "H3y Jud3" is easily found using a dictionary attack -- in fact, john the ripper's out-of-the-box rules has "l/ese3[:c]" as one of the single crack rules, and "Hey Jude" is most definitely in cracker lists which tend to include all popular movies and songs.
On the other hand, if/etc/shadow is already available to the attacker (i.e. the attacker has gained root privileges), weak user passwords is your least concern.

You need to work in the frequently referenced pasty-white-parents'-basement-dwelling-virgin stereotype there somewhere.
So it all depends on the type of particle you a firing at the target, whether it passes right through the armour to target the components you a particularly after...
X-ray or gamma-ray lasers could do this, but there are some (severe) practical problems involved. An atom emitting an x-ray photon tends to recoil a bit, so the photon has only part of the energy from the transition - not enough to cause emission of another photon from the next atom, as happens in a laser. And even if you did produce an X-ray laser beam - how would you focus it? Mirrors and lenses don't work that well with x-rays.
I'd think the obvious choice would be to go with a longer wavelength, as opposed to a shorter one. If your laser has a wavelength longer than the reflective surface's thickness (say 1 cm, microwaves), it will pass right through it like it was never there.
We can mine the Moon and possibly Mars, but what does Venus offer us? Fuel? I would think it is too hot for mining the surface (robotic miners capable of operating in the heat may not be cost-effective)
I was thinking more of sending the womenfolk back to Venus. Then, the rest of us go to Mars; and life imitates fiction.
I second this. most folks I know who love programming learned a nice easy language as a kid (BASIC in my case, a long while back). Python is easy enough to learn how to program in, but flexible enough to draw stuff on the screen, play sounds, talk to remote machines - mess with what the machine is capable of.
I'd definately pick a friendly language to begin with (and I'm not sure C or C++ fit that bill, I'm still learning good C++ practice after a decade of commercial use).
What you choose as a first language matters. It should be easy, and teach basic flow control in a very direct matter that allows for an intuitive understanding of those subjects (BASIC was the name of the game when I was young, python is where you'll want to go today). But I'd definitely leave the door open for C or C++ as well (hell, I learned C when I was 15). Buy a good book on python, and K&R to teach him C, and tell him to start out with python, and get into C if and when he feels like it.
TFA is dated 24 April, 2007 -- I'm pretty sure that this is old news.
Hmm, and it reaches us now. Assuming it traveled at the speed of light, it must have originated 1.25 lightyears away. It must have been sent from a relay station quarter of a way to Alpha Centauri.
Using simple, non-relativistic math, you would surpass the speed of light by accelerating at a constant 9.8m/sec in just under a year. That means you get to live on your spaceship with simulated earth gravity due to your constant acceleration. That means we don't need to turn the inside of our spaceships into pink goo to accelerate to relativistic speeds within a reasonable amount of time.
The only problem is fuel. How do you power a ship at 9.8m/s^2, or any other 'sizable' acceleration? for that long? And don't forget you also have to slow down, or you won't enter orbit around your target--although in the case of New Horizons, it's designed to blow by Pluto because it's not feasible to conduct a mission that *eventually* puts a probe into orbit around the minor pluplanetoid.
Another problem is the means of propulsion. Rockets are good for steering, but not for achieving huge speeds. The speed attained from a rocket is LOGARITHMICALLY proportional to the mass of fuel (hence multistage rockets, every mass reduction helps). They may work to escape earth's gravity, or even get to the moon and back, but it won't get you near the speed of light.
Unfortunately, the options are pretty bleak. Ion thrusters as well as solar sails are so slow it's simply not feasible for a manned expedition.
You would be right except relativity is an important factor and cannot be simply excluded. Your example makes the assumption that there are no relativistic effects, which is not correct, hence your conclusion is way off too. D-
Relativity is pretty weak up to very close to c. Even at 98% of light speed, the Lorentz factor (mass increase, time dilation, etc.) is only somewhere around 5. So, allowing for a decent fudge factor, classical physics isn't a half bad assumption.
So, making it to such speeds is not extremely unfeasible (fuel required would be around the same order of magnitude and such). The trade off is really the amount of fuel required to attain a certain speed, and the benefits in terms of time dilation you get.
Linux can be pretty fast to boot up, depending on what you want to run on it. I remember stripping down a Slackware boot script to boot an absolutely antiquated (well, 2001) laptop in 9 seconds. I reckon that should be about 2 seconds today with vastly improved CPU and disk read performance.
But then I ended up with an absolutely user-hostile Linux environment (people thinking vanilla Slackware is bad have no idea how deep the rabbit hole goes). I had to know exactly what command to run when, to fsck the disk every month manually, to run ldconfig after I've installed stuff, to run dhcp manually if I plugged it into the internet, etc.
Ah, great times.
