ruby-debug in 30 seconds (we don't need no stinkin' GUI!) —

Threaded Awesome —
Joe Damato and Aman Gupta show why and how Ruby (MRI)’s thread implementation sucks. Great presentation with lots of useful examples of using tools like strace and gdb to figure out where a process is spending time. Warning: you will be depressed and embarrassed after reading this if you currently target Ruby MRI.

Debug your shell scripts with bashdb —
“The syntax for many of the commands in bashdb mimics that of gdb, the GNU debugger. You can step into functions, use next to execute the next line without stepping into any functions, generate a backtrace with bt, exit bashdb with quit or Ctrl-D, and examine a variable with print $foo.”
