"""Download Danske Tursejlere / Blå oplevelser map items as KML, GeoJSON or GPX.

Data source: the public JSON API used by the "Blå oplevelser" mobile app,
    https://tursejler.eu/api/buoys/
This is much more stable than the old WordPress admin-ajax route — no per-page
nonce to scrape, no session, and the response already carries decimal lat/lon.
A bare GET on /api/buoys/ returns *every* map item (buoys "Turbøje", harbours
"Havn", lunch jetties "Frokostbro"); we filter by category/owner locally.
(/api/buoys/?buoy=true would return only the buoys.)

-- Shotwell photo.db SQLITE VIEW to query by tag_name

-- Usage after creating the view:
-- SELECT * from v_tagged_photos WHERE tag_name LIKE '%slo%';
--
-- (the view is as hellish as the db layout of Shotwell)

PlatformIO install on CodeAnywhere

For the Xenial distribution, there are some fixes needed, as PlatformIOs urllib3 depends on newer SSL libs.

So just get an older urllib3 implementation via PIP and copy over to PlatformIO.

Block sinks in sea water

You:

a block with length 0.35m, width 0.25m, height 0.35m weighs 12kg. How deep does it sink in sea water?

ChatGPT:

To determine how deep the block sinks in sea water, we need to consider the buoyant force acting on the block and compare it to the weight of the block.

The buoyant force is equal to the weight of the water displaced by the block. In this case, the block is submerged in sea water, which has a density of approximately 1,025 kg/m³.
