Oh My Zsh adds bloat but sets sensible default settings compared to vanilla zsh.
I tried using zsh without OMZ and I realized how many things are in OMZ which I took for granted, especially keybindings.
~150ms with minimal setup is good enough for me, although I would prefer <50ms.
Only if there is no additional information. Most buildings have polygon on ground level and height/number of levels.
It's possible to make more complex shapes
There are many solar plants not mapped due to lack of high quality, up-to-date aerial/satellite imagery, or volunteers.
Germany is country mapped best, not necessarily having significant share of solar.
I stopped using GMaps and I still don't think they are worthless.
Some companies buy fake reviews, some use shady techniques such as free drink/appetizer for a review. In my experience so far those are exceptions, not standard. I think corelation between quality and GMaps average review score is quite high - at least for restaurants.
I'm using it since their beta release in Google Play (in March?).
It works very well for me, I like it much more than OSMAnd (which is slow and too complicated).
I used MAPS.ME for a while but sponsored POIs, banking ads, tracking etc. was too much for me. Fortunately it's all gone in Organic Maps fork :)
OpenRailwayMap[0] is useful to see where High-Speed Rail has been built - choose Max speeds map style.
It uses data from OpenStreetMap[1] - free (as in freedom) map edited by community in a Wikipedia fashion.
