L’incroyable précision des horloges atomiques
Elles sont peu connues, et pourtant les horloges atomiques sont indispensables aussi bien à nos télécommunications qu’au #GPS. Elles servent aussi à tester des théories fondamentales de la physique. Et leurs prochaines applications sont encore plus impressionnantes.

🌍 Volevo segnalare wanderer, una web app relativamente giovane che permette di caricare tracce #GPS registrate o crearne di nuove e aggiungere #metadati per costruire un catalogo facilmente ricercabile.

E' hostabile in proprio, non c'è nessun tracciamento e supporta #ActivityPub per la sua integrazione nel #fediverso

Un bar, et un service de vidéo 24h/24 à cet endroit ?
Mais y'a RIEN à cet endroit, c'est un CHEMIN DE TERRE ENTRE UN CHAMP ET UNE AUTOROUTE (!)
Mais d'où ils sortent ces données ? C'est bizarre.
Elles ne sont absolument pas dans OpenStreetMap.
Ou alors ils empoisonnent leurs cartes pour prouver les vols de données.
Now the subtitle—in addition to showing the timestamps—contains a location pin icon for the origin GPS coordinates, and a globe icon for the last modified version GPS coordinates.
These are set manually, just to keep things more intentional and optimized, via two new ViewToolbar buttons: fetch current coordinates (for the most recent coordinates) … and set created coordinates, which will populate fields for a tiddler's origin coords.
The subtitle icons themselves function as buttons, which re-direct to a note that is generated via a template containing a geomap widget, and the coordinates as the note title, stored when either of the two ViewToolbar buttons is pressed.

after meeting up with and chatting with @liaizon about geotagging and note-taking … I've come up with a nice way to integrate geotags into my #TiddlyWiki
Thanks to @Jermolene GeoSpatial plugin, I was about to create some metadata gui elements which reveal a note's origin GPS coordinates, and its latest revisions GPS coordinates, by modifying the subtitle shadow tiddler.
