We just wrapped up the Advanced Mathematica Summer School, two weeks of lectures and on-site consulting and coaching for attendees in developing a Mathematica project idea. As a developer, this was an awesome opportunity to work hands-on with real users and develop a better feeling for (1) real world problems, and (2) ways that people use our products, versus what we may assume they want and what they know.
During the lightning presentations this morning, one attendee wanted to express his appreciation:
"I want to thank Wictor for writing some really cool code for me,
and I want to thank Paul-Jean for helping me understand the code that Wiktor wrote."
