Hey, fellow XML nerds & tag lovers!
If you happen to be at Markup UK in #London this week, and got questions about eXist-db, want to talk about XQuery, native XML databases, or just rant about trying to force hierarchies into SQL tables?
Juri and Duncan from the eXist-db core team will be in the house! Come say hi — we’d would be happy to talk 💬😄

How well does the hachure algorithm stand up to various complex curves?
In general these are not closed curves; the algorithm will close them off and treat them as such. (Hence the stray crosslines.)

More fun with crosshatched tilings
What if we applied a mutation function to the tiling?
#GenerativeArt interlude
What if you took a regular tiling pattern and filled each tile with random cross-hatching?

It was just the background for something else, but gosh it came out pretty
New -slim images for duncdrum/existdb!🚀
Now available for 6.4.0+, these come without stockapps in /exist/autodeploy — perfect for minimal base images or lean XQuery-only setups.
All distroless variants have a -slim twin 🧱
e.g. duncdrum/existdb:6.4.0-nonroot-j8-slim

More luminosity mapping
We saw circles yesterday. What if we mapped to spirals? Tighter spirals being darker. Here I alternate the orientation of the spirals because I think it looks better. Again, mapping colours as well as it makes it less boring.

Luminosity => radius
I also map the colour, because it makes things less boring
You've seen a million of these, probably, but I've been playing around with variations
