Good UI matters for CLI apps too. A small use of colour makes a huge difference for reading output. http://t.co/YsO0vpXZSD

Whilst SAT is NP-complete, I'm surprised to learn that 2-satisfiability can be solved with a linear algorithm: http://t.co/6oSPONVeoY

Disappointing to learn that Python 3 tries to guess encoding used in argv in shell scripts: http://t.co/38GwZU6ZEr

Linux fact of the day: "Exit codes greater than 128 are used by the shell to indicate that a program died due to a fatal signal."
