They’ve gotten pretty strict if they think your IP is a scraper (i.e. coming from AWS or another cloud provider even inside a full browser environment).
It’s about moving inside a state. I told the DMV of my new address, but my drivers license still has the old one. Maybe I could get it reissued, but that seems like a pain. Many people move more frequently than the license expiration period.
Not in rural areas. Maybe for suburbs. At least in SF ppl Uber a fair bit, but I suspect most trips on a night out are not replacing someone driving their own car.
The other tell is 3 leaves. From memory (so maybe wrong), they aren't hairy, but do have a slightly broken edge (can be smooth, but can have a little but not a lot of variation).
You need way more than one. Trees, storms, and cars take out distribution power lines all the time. Substations, which was got attacked, have less redundancy and way fewer spare parts on hand.
Contract’s don’t (more accurately almost never) pay for gas. Gas estimation is done when sending by the end user.
Some parts of gas estimation can be done statically, but some of the cost of certain operations are dependent on the data being loaded from the state. I’d like a tool to set an upper bound on gas usage (current approach is to execute the tx on pending state and add 10-30%), but solidity does not provide one.
