La note de MagicEarth sur le PlayStore est descendue à 1,4 (elle était à 4,2 à l'origine)
Félicitation aux robots-corpo fraîchement sortis des écoles de commerce qui ont dicté cette refonte 👌

1,9 étoiles sur 5.
Ah ouais avec leur dernière mise à jour, MagicEarth a très bien réussi à cramer sa note sur le magasin GooglePlay. 👌

Bien... CoMaps est absolument fantastique, c'est juste la navigation voiture qui posait problème. La dernière mise à jour a enfin un zoom automatique adapté au prochain changement, ce qui rend la navigatation *bien meilleure*.
L'indication des sorties est également amélioré (on a par exemple les numéros des sorties).
Pour ceux qui l'utilisent en voiture, il devient enfin *acceptable* et peut remplacer MagicEarth (info-trafic mise à part).
Pour autant, il n'est pas parfait: (suite)
#GPS
mmm... le changelog de la dernière version de CoMaps indique un changement intéressant, un reproche que je faisais à *TOUTES* les applications de GPS (sauf MagicEarth) : Un niveau de zoom automatique foireux et des intersections illisibles (coucou OrganicMaps).
Le niveau de zoom est maintenant adapté automatiquement à la distance du prochain embranchement, ce qui devrait en principe rendre l'utilisation en voiture nettement meilleur.
Je teste ça et je vous tiens au courant.

🛰️🇵🇱 GPSPATRON & Gdynia Maritime University analyzed GPS/GNSS Interference in the Baltic Sea over the last 9 months.
⏱️ 84 hours of GNSS interference (mostly jamming) detected.
📆 This October had 6 jamming incidents for 29 hours. It's intensifying ↗️
✈️ No correlation between terrestrial GNSS and ADS-B-interference
🚢 Maritime jamming sources were identified, with interference signals exhibiting movement patterns consistent those of vessels.
🛰️🔒 Galileo began yesterday encrypting the E6-C signal component of satellites E14 and E18, the two spacecraft in eccentric orbits currently used for testing.
These signals will remain encrypted from now on, and we expect the rest of the constellation to follow in the coming months. This marks a key step toward Galileo Signal Authentication Service (SAS), the civil and free spreading code protection service.

Studie: GPS-Störungen in der Ostsee werden komplexer und stärker
Bei den Unterbrechungen von Satellitennavigation bei Kaliningrad kommt es laut einer Analyse mittlerweile zu einem Wechsel von Spoofing- und Jamming-Angriffen.

Bon ben ça y est, je suis passé à la nouvelle version de MagicEarth.
C'est pas fameux 🙁
Et je ne parle même pas du fait qu'une partie est devenue payante.
J'essaie de vous faire un topo dans la journée.

Mit GPS-Trackern am Halsband sollen sich entlaufende Hunde jederzeit orten lassen. Wir haben getestet, ob das wirklich funktioniert.

I'm all for remote consultations as a first line of triage. So people don't have to pay for and travel to GP appointments we don't really need.
But a properly funded Healthline that didn't leave you on hold for half an hour could do that job. We don't need for-profit "telehealth" platforms.

C'était la bonne idée de mettre à jour mon #Fairphone Gen 6 alors que je suis au #Québec. J'ai le bug du redémarrage en boucle maintenant. Je dois couper mon #GPS pour qu'il soit un peu utilisable.

I built a more accurate Galactic GPS for aliens to find us!
In the 1970s, the Pioneer and Voyager spacecraft were launched into deep space - each carrying a message from Earth in the form of plaques and golden records. These included a now-famous diagram: the pulsar map, originally proposed by Carl Sagan, Linda Salzman Sagan, and Frank Drake.
It uses the positions and spin periods of 14 pulsars to show where we are in the galaxy, effectively a cosmic return address.
But there’s a catch: the original map used canonical pulsars, which we now know can glitch and show timing instabilities. Back then, millisecond pulsars hadn’t yet been discovered (they came in the early '80s), so they weren’t included.
As someone studying millisecond pulsars and their long-term timing stability for my PhD, I decided to write some code to rebuild this iconic map - with a little upgrade.
Enter: the Millisecond Pulsar Map.
This version features:
- A top-down view of the Galaxy, with a central measuring bar showing our distance (8 kiloparsecs) from the Galactic Centre.
- Radial lines showing the distance to each millisecond pulsar. These can be measured against the central measuring bar to work out this distance
- Binary encodings for each pulsar's spin period and spin-down rate. These parameters will remain much more stable over the long term.
- A decoding scale to interpret the binary inscriptions.
With 40+ years of high-precision timing data, millisecond pulsars are far more stable than their slower cousins - making them ideal for building a map that could stand the test of cosmic time.
This also highlights how millisecond pulsars could be used as an intergalactic GPS network (because these stable pulsars are like cosmic clocks distributed across the sky). This might be an application for future spacecraft to navigate around the Solar System. Have a read of this article for how we are already building this technology now: https://www.spaceaustralia.com/feature/breaking-free-shackles-terrestrial-time
So, if some distant civilisation stumbles upon this new pulsar map ... well, they’ll know exactly where to find us.
The question is: do we really want to leave our full galactic home address out there?!
