In other words: I do maps on websites, maintaining the Leaflet JS library when I can, but working on Gleo (my own JS+WebGL library) otherwise.

Reflexión sobre esas cosas que la gente llama IAs*:
Son el comodín del público del 50x15.
Te van a dar una respuesta, y te van a dar lo más estadísticamente probable, y nunca te van a decir "no sé". Que para cosas sencillas puede estar bien, pero para cosas complicadas no te deberías fiar un pelo.

Do I know any Serbian OpenStreetMappers? It seems that the folks at the Belgrade airport forgot to put the OSM attribution before printing the info posters. Somebody should tell them.
(Update: @kokan will handle the issue locally)
(Compare with OSM mapnik tiles at Z=13, https://www.openstreetmap.org/?#map=13/44.78431/20.44041 )
In today's #gleo news: wind data!
Or, more technically: a 2-band raster covering the globe and properly warped (EPSG:4326→EPSG:3857) containing UV speed data, visualised as a particle trail simulation.
Thanks to the #FOSS4GE2025 for providing the environment that has let me pull this off.

In today's #gleo news: Different per-point colour on Stroke symbols.
And, since Gleo can take a symbol and replace RGBA colour into heatmap intensity, it's easy to make a visualization of a magnitude (e.g. vehicle speed) over a trajectory.
You can try this out at https://ivansanchez.gitlab.io/gleo/repl.html#HeatMap%20%2B%20intensified%20Stroke ; note how the heatmap intensity is summed at the places when the line overlaps itself.
In today's #gleo news: the new `minzoomify` symbol decorator!
Symbols can now disappear when zooming out (or in) past a given scale factor. This is very much like @leaflet 's `minZoom`/`maxZoom`.
