Let Go

After years of trying various methods, I broke this habit by pitting my impatience against my laziness. I decoupled the action and the neurological reward by setting up a simple 30-second delay I had to wait through, in which I couldn't do anything else, before any new page or chat client would load (and only allowed one to run at once). The urge to check all those sites magically vanished--and my 'productive' computer use was unaffected.
-
Complex Conjugate

Fun fact: if you say this every time a professor does something to a complex-number equation that drops the imaginary part, they'll eventually move the class to another room and tell everyone else except you.
-
Positive Attitude

Having a positive attitude is almost tautologically good for your mental health, and extreme stress can hurt your immune system, but that doesn't mean you should feel like shit for feeling like shit.
-
Constructive

And what about all the people who won't be able to join the community because they're terrible at making helpful and constructive co-- ... oh.

-
Bad Ex

Since the goatee, glasses, and Seltzer & Friedberg DVD collection didn't tip you off, there will be a $20 negligence charge for this service.

Still No Sleep

I'm not listening to you. I mean, what does a SQUIRREL know about mental health?
-
1996

College Board issues aside, I have fond memories of TI-BASIC, writing in it a 3D graphing engine and a stock market analyzer. With enough patience, I could make anything ... but friends. (Although with my chatterbot experiments, I certainly tried.)
-
DFS

A breadth-first search makes a lot of sense for dating in general, actually; it suggests dating a bunch of people casually before getting serious, rather than having a series of five-year relationships one after the other.
-
3x9

Handy exam trick: when you know the answer but not the correct derivation, derive blindly forward from the givens and backward from the answer, and join the chains once the equations start looking similar. Sometimes the graders don't notice the seam.
-
Principle of Explosion

You want me to pick up waffle cones? Oh, right, for the wine. One sec, let me just derive your son's credit card number and I'll be on my way.

Revolutionary

I mean, what's more likely -- that I have uncovered fundamental flaws in this field that no one in it has ever thought about, or that I need to read a little more? Hint: it's the one that involves less work.

Pandora

Period

413 nanohertz, by the way.

No Pun Intended

Like spelling 'dammit' correctly -- with two m's -- it's a troll that works best on the most literate.

Purity

On the other hand, physicists like to say physics is to math as sex is to masturbation.

Command Line Fu

When designing an interface, imagine that your program is all that stands between the user and hot, sweaty, tangled-bedsheets-fingertips-digging-into-the-back sex.
