I like the TTR because it allows me to check if it make sense to spend some time on some tool and make me discover new tools/approach that are already vetted.

I like the TTR because it allows me to check if it make sense to spend some time on some tool and make me discover new tools/approach that are already vetted. I like also the "Call me maybe" serie by aphyr (aphyr.com) because I can check if it make sense to spend some time on a distributed system. Do you have any other resource that could play the same role?
