"Each spring, billions of Bogong moths (Agrotis infusa) migrate hundreds of kilometres south to the Australian Alps, guided by the austral night sky. The discovery that they can find their way using only the stars — reported in an 18 June Nature paper — makes this moth the first invertebrate to be observed using celestial navigation for long-distance journeys."

»Wie Mathematik hilft, schneller durch die Stadt zu kommen:
Am Complexity Science Hub in Wien wird errechnet, wie Pendelzeiten für alle Verkehrsteilnehmer durch andere Ampelschaltungen verkürzt werden könnten«

Dies kann sicherlich sich auch für Radfahrer oder Fußgänger sich lohnen. Ist es 1-zu-1 auch für andere Städte oder gar für Vor- so wie Kleinstädte und/oder ländliche Umgebung umsetzbar?

An Ampeln wie dieser beim Wiener Museumsquartier müssen Fußgängerinnen und Fußgänger weit länger warten als Autos.

#Google free #Navigation with #TTS-engine (Text to Speech) #GraphenOS

When I use a Google free navigation system on the Pixel 8a, the crucial point is the voice output. The operating system GraphenOS does not have any installed speech output. I had to install a speech output protocol first. (TTS-Engine, RHVoice) I am currently using "OrganicMaps"
@GrapheneOS developers please make it more easy to set up TTS-engine for Navigation. (RHVoice as example)

sadly there is no german laguage. available in RHVoice. https://image.nostr.build/800b83a5fe5e5fd4d9a1c7e11b10d10c063761dd7203306e069ea2defd6c05da.jpg
Continued thread

Eight times in 3½ hours a boat crashed into me while I was tied up along the shore.

I have just moved the boat forward, leap-frogging two boats.

And in the process I myself hit 2 boats — inevitable, unfortunately, but I was unwilling to continue being crashed into by people for whom the wind is somehow a surprise.

Six boats have crashed into me in the past 3 hours, scraping and bouncing all the way down the length of the boat. The wind is too strong for occasional- and hire-boaters but it doesn't stop them, so they get blown into me as they clear the trees.

I want to move but the strong wind also means I cannot move the boat. There are 2 boats immediately ahead of me and I could never clear them.
