Bash: I think I already knew this, or at least had a general feeling that it was true, but now I read explicitly (in Miell's Learn Bash the Hard Way) that wildcards are not the same as regular expressions.
Web apps/postgres: connection pools could have a significant effect on performance when there's a fair amount of traffic.
Python: you can include on requirements file inside another. Useful for a base/production file and then a separate dev reqs file.
Ansible: set_fact allows you to create variables at runtime (most variables are created at beginning of play).
