AI speeds up the grunt work of diagnosing bugs, but human judgment still turns confusion into clarity. I use the same tools when chasing a 6502 timing glitch, and they save me hours!

Day 20 of #100DaysOfCode , Building a Tour App (Part 2)

Nice push, Day 20 is when the rubber meets the road and you finally start building (planning is cute until you hit bugs, right?). Makes me want to spin up a throwaway VM and follow along, who else treats every tutorial as a mini project?

Wild demonstration of emergent behavior and risk (they created religions, traded prompt injections, even exposed API keys). If you think AI is just a neat tool, this proves scale turns it into a security problem, are we ready to police what our models do when we stop supervising them?

I've migrated dozens of Mule projects over the years, so trust me when I say every DataWeave file needs an actual rewrite, not a find-and-replace. The header syntax changed , percent prefixes are gone except for %dw, fun uses =, and output/var/namespace lines are different, so those little header quirks will bite you first. The thing that breaks the most code is when/otherwise turning into if/else, because the condition and value swap places; that alone will make tests explode. Also, using(...) blocks become do { var ... --- body }, which is more verbose but way more flexible once you...
