I do have to question whether it is the best use of municipal resources to have NYC DOT apply salt today. (38/34 degrees, raining)

Property Taxes in NYC are a Mess. Here’s Why Even Renters Should Care. They’re the engine of the city’s budget, but unequal and outdated. Here’s your guide on how property taxes work β€” and how they affect everyone, not just owners.

the checklist ID S46116491 is entered, highlighting that user and their connections across the network

To find your own dot in the eBird network, you just need the ID of one your checklists (e.g. S46116491, which you can find from the URL of a checklist, ebird.org/checklist/S4...)

Then enter that ID into subject.space/projects-sta... and the visualization will show connections for that eBirder πŸͺΆ

if you look at the model evolution, you can see why: it depends on accurately forecasting where the band of heavy precipitation will be. www.pivotalweather.com/model.php?m=...

the european model still has the heaviest snow more offshore, giving a much lower forecast for nyc.

It would be almost exactly the ~20x base fare multiple for a monthly pass that you have pointed to as better than the MTA's ~45x many times

obviously I was tongue-in-cheek with the name, and the scale is not comparable.

As I understand it, RAD PACT is less about privatization for privatization's-sake, then it is an arbitrage play for housing aid dollars at the federal level. Privately-run subsidized housing can be funded through Section 8, unlike NYCHA-run buildings which need money from a shrinking Section 9 pool.

Shipwrecks, Sham Papers and False Flags: Tracking the Company Behind It All - bellingcat A shipwreck in India, an ammunition seizure in Senegal, and a raid on an oil tanker in Malaysia - all involving one recurring figure: Captain Suniel Sharma.

A maritime "false flag" isn't a conspiracy theory - it's a vessel sailing under fraudulent registration from a country that never authorized it. And now it's happening at scale through the web.

Maybe consider OpenLayers for this, which can use a COG directly? I’m surprised MapLibre can’t, so I’d check that Codex output too
