There's a logical error in your first step. When doing algebra, one doesn't "move" the 0 from the left side by the right side, they multiply both sides by 0. The usual next step is to cancel out the left side and proceed, which you implicitly did but didn't explicitly show the step. However, when you multiply by 0, you have:
0/0 = 0*inf.
You CANNOT assume 0/0 = 1 and cancel it out because it's not uniquely defined; 0/0 = x for every x in the real numbers, imaginary (complex) numbers, and every other field.
To see if 0/0 = 0*inf holds, we need to know whether 0*inf exists in a field, but 0*inf = 0, we know this because part of what defines fields is how limits work with inf:
lim_x->inf x = inf
It's axiomatic. So when we apply this to 0*inf, we get lim_x->inf 0*x = 0. This gives us 0/0 = 0, which IS true.
Here's the catch: 0/0 does not equal 0 uniquely. The logic is such that if EVERY number can equal 0/0, then NO number in any field can define 1/0. Zero attacks every number but itself with decidedly beyond infinite feebleness.
Clearly "positions" means investment positions, so it's probably something like:
"Golly mister! You've been standing like that for hours! What gives?"
"Well son, my investment manager told me it would pay to hold my position!"
Hilarious! Nothing funnier than investment managers, they prove prostitutes aren't the only ones who use different positions to fuck people out of their money.
At the time I used straight LaTeX, but I made it work. The trick was to get a good editor and set up keyboard shortcuts for common things to blaze through the process quicker. Add on top of that a bunch of renaming functions in the preamble to save keystrokes for other common actions and keeping up isn't much of a problem.
That being said, I'm going to cast my vote for Lyx because you can still do all I suggested above, but it greatly aids in building tables, matrices, and other things that'll slow you down a bit. And don't be afraid to use shorthand that won't format properly when necessary, as long as you know what it says you can always fix it after class or during a lull in the lecture; I find this typically takes less than 5 min. And use lots of white space. And reconsider what the best way to keep notes is; when you have a medium with the flexibility of files, folders, etc, I find it's usually better to take notes by topic instead of chronology of when it is said.
Funny story, took notes all semester for my stat class that way and we got to use 1 page of notes for the final. About 20-30 minutes of copy/paste-ing gave me every equation we used, qualitative descriptions of what they do and when to use them, and a whole host of other useful stuff. Never studied beyond doing my homework (which I only did most of the time) but I got a 297 out of 300, highest grade in a class of ~150 and about half a standard deviation above the next highest score...
Or most of them, anyhow. Wow, that's clever though. We've been trying to decide the outcome of wars around the world pretty regularly since WWII, this just provides a very efficient means of doing so. It also gives a big disincentive for people buying US weapons on the black market (well, the really bad ones).
Of course there's always the fear of hackers figuring out a way to kill the kill switch, but at least it's one more obstacle. It'd probably be a good idea to ensure none of our craft, etc, have these kill switches though, just the ones we sell. I'm sure we try very very hard to protect the switches, but security systems of all kinds get broken, it's easier to find exploits than it is to create a system that has none whatsoever. If lives (potentially thousands or more) depend on it, why take the chance?
A noteable exception to this rule, btw, is when applied to a girl you're even slightly interested in; the right move is to, while channeling the complete confidence of Kirk, refuse to help her and, with a smile on your face, poke fun at her computer skills. If done right, she'll panic at the failure of her sexual prowess and will proceed to plead for your assistance to prove she still has control. She does not, you do. Refuse again, she'll persist, so explain, still while smiling and channeling Kirk, that you know girls love to get guys to do stuff for them for free and that you're not so easily controlled. She'll probably act offended or more desperate for help; either way ignore her emotions then offer her a compromise: if she cooks you dinner, you'll fix her computer while she's cooking. Bring a semi-inexpensive bottle of wine, then without asking pour her a glass to drink while she cooks. Fix her computer, come back and sit to her right (or left, not across), eat dinner while teasing her that her porn browsing adiction will only lead to more problems. If this doesn't sound right to you, consider the following: you have shown yourself to be ultra alpha-male, you have put yourself in a position of control, you have a date with a girl you're interested in where she is submissively making you free dinner, you kept her busy so she didn't see how nerdy you look when you hack, and you've left her feeling grateful for it all.
I remember hearing about a system that uses photography and computer anaysis on the cars to figure out exactly how long you parked and whose car it is. Tie that to a credit card and you don't have to do anything. Except it also ends parking ticket revenues, which is priced in to the system. Would you be willing to pay more so that you'd never pay late fees again (a la Netflix)to compensate for the revenue loss? Perhaps capturing each minute of all cars who weren't paying for parking before (the ones who would have gotten tickets) would take care of it. If that's the case, it's really win win, if you think about it.
Looking at bills from 17 cities, it's no surprise that the city with the highest level was Washington DC, where up to 95% of bills gathered there tested positive.
Why is this no surprise? New York has Wall St, coke is imported into many Florida and California cities, etc. The only thing remarkable about DC is the presence of the Government, and since so many people here (I'm a resident of the District) want to get high levels of clearance for their jobs, most won't touch any illegal drugs. Really surprised by this, even though I do know where to get dank coke
Can I just say I love your rage and how everyone seems to ignore it because you're speaking sense. "Bullshit, you motherfucking liar." "Now go back to sucking Obama's cock, you know-nothing retard." Brilliant, though I would have added a few !s for good measure.
And to add my $0.02 to those environmentalists who don't seem to get it, if we crush the economy we crush our ability to innovate right now, and we crush education (our ability to innovate in the future). Innovation is the only way to solve these problems; we have too many people in the world now, and unless you want to give up all your tech (including your computers and the Internet), we aren't getting back to a sustainable level without it.
Real computer scientists like having a computer on their desk, else how could they read their mail?
