    Related project I did in 2014 tried to do this. I was a web developer so used the web audio APIs to trigger a recording when the decibel level exceeded a certain value. I was livin…

    I think what Claude generated code is still missing is the feeling of "I learned something from reading this code. Reading this code made me a better programmer". We're not there y…

    I think mbtiles are being phased out for pmtiles because no DB required and can be served from static storage like R2/S3 (with a worker but hopefully the worker part goes away and …

    Fair. I used Phoenix because it's the only published city shading plan I've come across. It could just be that arid/hot climates are the places trees are needed. The study linked w…

    Planting trees is hard. Phoenix AZ has a tree planting program called the Shade Phoenix Plan and they publish public reports. Watering and maintenance are a big cost. Iirc it's abo…

    There are a few other reasons that aren't baffling: roots destroy water pipes and heave sidewalks and pavement. They can interfere with power lines as well. :(

    You can train ML to recognize vegetation in satellite photos and further train it to estimate its height +/-3 meters https://github.com/facebookresearch/HighResCanopyHeight
