How do you compile your code? (Thompson reflections on trusting trust)

And beyond source-code:

How do you shield your equipment? (tempest, also active attack)

How do you guard your equipment? (evil maid)

Real life is the triumph of convenience over security :(

Convenience is exactly what I use in my real life. My texting security is whatever Apple implements in iMessage. I'd be a lot more paranoid if I were a "smuggler" or "revolutionary".
