"I will probably hate myself for publicly releasing a list of this kind, but a lot of people do these things anyway, so it should not matter.
So here goes, in no particular order,
- Obviously, tell them to take a look at your PC that has been taking a long time to boot these days
- Beg them to "hack" a particular Facebook / GMail / Anything account because
- Tell them about that time when you were _this_ close to being a programmer yourself
- Enlighten them about that world-changing idea you once had in 5th grade, and ask them if they would like to be a part of your "company" (note that you do not need to know what you are talking about)
- Ask them for lessons — not programming lessons, but again, "hacking"
- Use UNIX and Linux interchangeably in conversations
- Argue over the fact that Windows is now multi-user, becuase it now supports multiple "accounts"
- Question their choice of Operating System (usually Mac / Linux) — over and over and over
- Ask them if they've "designed" any "new software" over the weekend. OVER ONE WEEKEND. Obviously, this doesn't work if you only do it once. So do it for a year."
There are obviously a million others. But you get the gist. A lot of programmers are good people (or at the very least, closet sociopaths), so you might see this reaction,
