✍️ Geohashes for my photos
Mathematically shorten GPS coordinates

Dealing with photos and GPS coordinates has recently become a bit more cumbersome thanks to Google's arrogance. #Geohash, a simple mathematical system for generating short codes that dates back to 2008, could be a solution. I've integrated it into my site...

Фильтр Калмана, geohash fog of war и три реджекта Apple: как я собрал GPS-трекер на SwiftUI

В 2024 году Google тихо убил Timeline в Google Maps. Историю местоположений перевели в «локальный режим», который на практике работает через раз - данные теряются, синхронизации нет, а у многих просто исчезли годы накопленной истории. Для меня это было важно: я много езжу на машине и хотел знать простую вещь - сколько конкретная поездка стоит в бензине. Ничего подходящего не нашёл и решил написать сам. Я бэкенд-разработчик, до этого проекта не написал ни строчки на Swift - дальше про то, как за месяц вечерами собрал GPS-трекер с фильтром Калмана, fog of war на geohash и Live Activity.

#SayWhere Geocoding System: Human-Memorable Geographic Coordinates

Auf der Insel #Jamaika bereiten sich die Menschen gerade auf einen #Hurricane vor und nutzen zur Kommunikation #Bitchat!

Wünschen wir diesen Menschen alles Gute, damit alle überleben!

Die #Geohash Funktion von Bitchat kann echt nützlich sein!

it's not too hot and my urgent todo list is lighter than usual, so it's time for #todaysBikeRide and #geohash expedition again!

The geohash was in an unremarkable sunflower field, so I stopped 11m away, staying on the road. Good enough for me. I found an abandoned bus from the city of Nevers, pretty much the other side of France, with a very late 1990s livery. Also went to the nearby artificial lake and found "interesting" things in the tiny library

Just learnt about the #quadbin spatial indexing. There is not much information about it compared to #geohash, #h3 or #s2. Has anyone worked with it before? Are there any pitfalls that I am missing, because it sounds freakin cool.

Any deno kv experts out here?
For FLOSS ActivityPub Clients:
I am looking for best practices for a key which has a geohash as secondary index and might be searchable by Date as well, like an as `Event` with a `location`
:)

What is going on with #geohash this weekend? Why are the points since thursday in pairs, a few hundred meters from each other?

#todaysbikeride and #geohash expedition was supposed to be a simple and quickly done thing. The target point is just 5km from home.

That was counting without the strong headwind and one of my tires experiencing a Rapid Unscheduled Decompression event, about 1km before reaching the target, so I had to walk the remaining distance and then all the way back home, while carrying the bike (I didn't take my bike lock with me, so I couldn't leave it at the accident place and recover it on the way back)

#TodaysBikeRide and #Geohash expedition. It's been a while since I went out! Well I guess the 3 day weekend helps with recovering from a week of work, doing chores,and then having abit of time and energy left. I should do that more often.

Anyways, thegeohash point today was in someone's garden, and unfortunately they are not playing geohash. So I could not get closer than16m in the backalley.

#TodaysBikeRide is a #GeoHash expedition alongsioe the Garonne's Lateral Canal to Eurocentre, a logistics platform north of Toulouse with lots of warehouse, a mail sorting center and the like. Nothing new for me: I used to work there a few years ago,when the owner of a company I worked (as a software engineer) for decided he didn't want to waste time in traffic jams entering the city, and moved us outside the city. Leading to several of us finding other jobs nearer to home.

#TodaysBikeRide and #GeoHash expedition brings us to the village of St Sernin, once again in the middle of a field, but I got quite close this time

#TodaysBikeRide and #GeoHash expedition. Once again the target point was in the middle of a field, but I got "close enough". It was very slightly raining during 2 hours while I was out. The sun came out just as I came back home.

#TodaysBikeRide and #GeoHash expedition. The target point was not quite reachable (would have to go down a few meters, seemed somewhat dangerous, and no road on the downhill side to get back). And then it started raining, so I didn't stay there very long.
Fun thing found nearby: some person owning a closed restaurant which has a Google Maps pin saying "PLEASE DELETE THIS"

Made a video of my pseudorandom #geohash #unicycle adventure from yesterday: https://www.youtube.com/watch?v=nrlpUz9nL_E

Also wrote it up on the geohash wiki: https://geohashing.site/geohashing/2023-03-18_30_-97

Sadly I was only able to get within 5m of the hash point, so had to settle for the "No Trespassing" consolation prize achievement.

#TodaysBikeRide and #geohash expedition. I couldn't reach the exact geohash point as I didn't want to step or ride into a freshly planted field. Well, I got close enough, and the fun part is the journey to get there anyways.

I heard it's a good idea to make an #introduction message here!

I'm a developper for the @haiku Operating System and several other opensource projects. I also do some #demoscene things mainly with 8-bit computers, and some electronics projects.

On weekends I post about my bicycle rides and I may attempt reaching #geohash coordinates or do other silly things.

I am worried this planet will not be suitable for human life in a too short time.
