Money from FOSS-projects

What, if any, are the most popular ways to get some money from a FOSS-project? I see that many projects ask for donations, and some of the larger ones do get a decent amount of donations.

Examples of great software design and implementation

I hope this isn't a duplicate... What is the most solidly designed and implemented software system/framework/application that you've come across?

Are there opensource alternative for StreamBase?

I worked with StreamBase in a previous life, and found it to be very useful for processing streams.

I have been a working programmer since the turn of the century and I have always been fascinated by the open source world.

Ethics of copying 20 lines from a "Free" project

Disclaimer: I know you're not a lawyer! :) This question is for university assignments, not work nor personal.
