I'm investigating whether to put some effort into flushing out personas and wanted to evaluate what works well and what isn't worth the effort. My own experience has had mixed results. If you worked someplace that had very helpful personas and willing to share your insight, would love to chat.

i was looking to see if using AI (Firefly) would save me time for a simple task but prompt engineering is an art in itself

From the Still Watching podcast: “The nominees for greatest comedy series of all time were Arrested Development, 30 Rock, and Enlightened.”

This surprised me because I’ve never watched or heard of Enlightened. I’ll give it a try.

First job out of college was QC at a company called Texterity. I proofread ebooks - Palm, Rocketbook, pre-Kindle era. If there were formatting issues I had to fix them. I grew bored of that so learned Perl & regex to automate the process. No more QC needed, so I was moved into engineering instead.

I agreed to do a guest talk next week for a class at Carnegie Mellon. I've been a speaker at re:invent, gluecon, pycon, developerweek, embedded linux conference, o'reilly software architecture, etc. but prep for this one feels much different.
