Taught students who later used knowledge gained in my course in their careers. Yesterday, I received this email from a former student, and I was shining the rest of the day:
I took intro to Perl in Fall ‘07 and just wanted to send a note of thanks. I found the slides you put together for that class to be really helpful and use them as my main reference. I’m actually in Electrical Engineering, so using Perl is a great time saver for me with mostly just reg exps (Unfortunately data acquisition manufacturers have wildly differing standards on how to save ASCII data, and almost no program is compatible with any way they choose to do it, so hooray for parsing 25k+ lines with like ten lines of code). I found myself visiting the CS department’s site every few days to refer to your slides and eventually just downloaded it all to have as a reference.
