From other sites, it seems it uses a Mac Mini in a server room as a proxy for iMessage to accomplish this, with the massive drawback of having to provide Nothing your Apple ID credentials.
I've sort of done this using the Walk score transit heat maps (they have similar for biking and walking as well) for getting a more broad feel for what areas are walkable/bikeable/less car dependant while house shopping, using a user script that takes the map tiles from Walkscore and injects them into the Google maps instance on Zillow. However, you could definitely generate the distance from a point heat/contour maps using QGIS/OSM data and overlay the tiles that way as well.
Would be super nice if this was built into Zillow, or any MLS browsing tool for that matter...
Indeedian here, thankful to not have been in the 2200.
Was a bit chaotic this morning, it doesn't seem like there was any clear pattern to who got layed off. Managers were given no advance notice for this either, know our manager was trying this morning to figure out over Slack who was affected by asking everyone.
