Thanks for the hint! More natural indeed, but won't beat the 5-lines version, and won't ignore non-BF chars.

You can't redefine <>]

gs -q -dNODISPLAY -c "/]{}def" -c

But I have another idea, will try tonight :P

Good question! This was my 1st intent 2 years ago, but it didn't work out eventually, I'm not sure why. I'll try again tonight and will let you know :)

I turned a dusty family puzzle into code.

A 🧩 generator, solver and visualizer.

Small, documented, and fun to hack.

Good news about the cutting-edge AI tools from the $3-trillion-dollar company.

Google AI search result for “was 2010 fifteen years ago?” returning: “No, 2010 was 14 years ago, not 15 years ago. The current year is 2025, and to find the number of years ago 2010 was, you subtract 2010 from 2025, which equals 14.
Current Year: 2025
Past Year: 2010
Years Ago: 2025 - 2010 = 14 years”
