Adding more fun data to my datasette instance.

Vincent D. Warmerdam @koaning.bsky.social · 07/09/2026

I wish people would share fun datasets more. So I made a little video on datasette to help motivate what's so cool about having your own little data-sharing-instance out there. youtu.be/RSUfvh9MowE

Why build a final solution when you can build the lego bricks instead.

I gave a demo yesterday to my colleagues that went so well that I figured I might as well make a recording of it right away. It's super early, but it's a v0 in a direction of "more humane coding experiences". May it offer you something to think about! youtu.be/BrQLCqofc30
