If you write any code, and there is anything you need to find out, you should be trolling Stack Overflow (SO). It’s astounding what you can find, and how willing people are to help (unless you write a terrible question, then you’re chastised).
Just yesterday I realized my string formatting skills were not advanced enough to parse the horridly formatted NEIC moment tensor solutions (here’s an example). Hi ho, hi ho, it’s off to SO I go. I wrote a question, and within an hour I had two useful (and different) solutions to work with – this saved me probably a day or two worth of work.
