If you didn’t run code written by assholes, your machine wouldn’t boot
This was passed on to me by Ben Elliston, ex-gcc hacker and good guy. Amusing in context, but the corollary is that working on free software means you'll encounter such people.

Don't give bullshit advice
I chatted with a young guy last night about his new startup idea. He’s got a vision for a social commerce app with a few cool spins on it. As I listened to him, I was thinking about how I had heard this exact pitch half a dozen times before. I also knew I had a lot to offer him in terms of help. I have a good friend…
