Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Answer: How To Get Latitude & Longitude of a Address using python
You can simply use geopy API to get longitude and latitude from address. geopy includes geocoder classes for the OpenStreetMap Nominatim, Google Geocoding API (V3), and many other geocoding services. The full list is available on the Geocoders doc section. Geocoder classes are located in geopy.geocoders. Here…

Btreefs generates executable code at runtime to unpack btree nodes
I have had a lot of "fun" with this feature in the past. It has earned a permanent place in my setup script:
ALTER SYSTEM SET jit=off;
Basically a performance blackhole for more complex queries. Most OSM related projects disable it straight away as it only creates headaches.

[Help] searching address
Because osm.org and OsmAnd use different search engines. On osm.org it uses the Nominatim geocoder which is good at parsing addresses the way we are used to writing them. It is also running on a server with a lot of storage and memory resources. OsmAnd is built for offline use so it can't use Nominatim and has much more limited computing resources available to it. It is searching through the map files locally on your phone and however they have chosen to implement that search algorithm seems to perform poorly on addresses.

Kako riješiti različite verzije istih adresa ulica?
Ako skupa s adresama imaš i njihove lokacije možeš i koristiti gotov geocoder (e.g. Nominatim je free i koristi OSM podatke, možeš i deployati svoju instancu), pa iz rezultata naći geometrijski najbližu adresu koju imaš.

Let's build a Google Maps clone with React, Leaflet, and OneSDK
Then implement a use case. We are going to use Geocoding use case with Nominatim provider. But you can, of course, use a different provider. Copy the example code into your server.js file and make a few changes, so we can send the information we will receive from the user:

MicroG Qs
There are reasons why this tech was developed: because GPS can take a long time to sync up to the satellites, because GPS often doesn't work indoors, because your phone can keep a local cache of locations, and so you have the ability to find places by name or address (Geocoding) using nominatim ( https://nominatim.org )

Digital prepping must haves?
and nominatim which does the geocoding/reverse geocoding: https://nominatim.org/
- Bulk/batch geocoding for cheap?

How do I go about with this project idea
Then it depends on how the location data is conveyed in the group chat. If it's a text message you need to parse it and possibly use a mapping service to do geocoding. Eg. convert "22 Main Street" or "upper Brooklyn" into GPS coordinates. Besides Google Maps API you can maybe use OpenStreetMaps via Nominatim. If it's something more like "we just passed John's house" then you need to figure out how to write some logic to determine a location from that. Or maybe they just used the WhatsApp location share feature, then you probably don't need mapping at all.

OpenStreetMap proven to be a highly accurate map in top US cities
Interestingly with almost nothing to do but walks around the city, Covid is the first time I started actively contributing to OSM. Although StreetComplete [1] definitely helped there, albeit just as a gateway for actually updated POIs, which still required the web interface.
