My vehicle automatically sets the parking brake if it senses it is on a steeper slope so I never consciously make a decision to set it.

How does that compare/contrast to the nuclear physicists speaking out during the early part of the 20th century?

They still seem to be gaming the system these days. I constantly see them clearing the order out and printing the ticket to stick it somewhere temporary so their time metrics look low, but now I get a notification in the app my order is ready when it actually is not.

I'd like a HDMI cable tester as well, I can't seem to find one that works well with my high refresh monitor.

No, that's for the warmup. The real puzzle only has a .gds file available.

I was going to say you were missing this one but I'm not sure if it's still open after the county purchased it.

Once rust starts, it is porous & flaky and allows more oxygen to infiltrate and hit the next layer of iron. The reason it is porous & flaky is due to creating a mix of FeO and Fe2O3 which have different crystal structures so it doesn't create a nice protective barrier.

It'd be a smaller amount that gets injected into the stratosphere, as opposed to what we normally release into the troposphere. A quick skim of the wikipedia link seems to suggest 5M tons in total, not sure what the annualized basis would be.
