This is where Finland and Sweden excel. Because they have mandatory military service, everyone with a gun has been trained in all aspects of it's use/care.

Article I Section 8 parts 15 and 16 empower Congress to require such training every member of the militia, and they have indicated that the militia is comprised of every able bodied male citizen, aged 17 to 45. (10 USC 246)

Congress can require training on safe handling. They can require training on the laws governing use of force in self defense and defense of others. They don't need to mandate additional military or militia service to achieve this.

A $4 tip plus $2 from the service nets me $6. I average 3 to 5 deliveries per hour, grossing $18 to $30 total. Minus $3 to $5 in expenses, and I'm earning $13 to $27/hr on that. Not great, but not terrible.

That was uncalled for.

I imagine we'll synthesize whatever chemical is inhibiting the methane production and it'll become a standard feed supplement.

Hopefully, it can be produced by some type of GMO grass and can be sown into hay fields.

In my area, I would not feel insulted by a $4 tip for a ~2-mile delivery.

The hotter it gets, the thicker the oxide layer form

This is accurate enough for tempering of most cutting tools, but technically, the oxide layer will continue to grow if you hold a lower temperature for a longer than normal time, and might not fully develop if you reach a higher temperature for a shorter than normal period of time.

This property useful if you are trying to develop a specific color rather than achieve a specific metallurgy. You can heat to a lower temperature for a longer time to develop a deeper, more consistent color.

In my experience, it's easier to develop colors with an oven or propane torch rather than a forge or acetylene.

I won't say that this blade is properly heat treated; it probably isn't. In welding, the problem is the wide variation of heat affects in a very small zone. You can have material that is very brittle just millimeters away from material that is very soft and ductile.

You're describing "normalization", which is a process that makes steel uniformly tough, but "plastic". When you flex it, it bends, and stays bent. "Annealing" is a similar process, where the temperature is raised a bit higher, and the cooling slowed even more. "Annealing" leaves the steel very soft.

In tool making, you're first looking for high hardness (acquired with a "quenching" process). This makes it very brittle; it has no elasticity.

Next, you're dialing back that hardness with a "tempering" process, which is done at a lower temperature than the normalization process, and the cooling can be much faster. When tempered, it's still very hard, (significantly harder than "normalized") but now it is slightly elastic. It will flex, but beyond a critical point, it just snaps; it probably won't take on a permanent bend.

These colors are oxide layers that form at temperatures in the "tempering" range.

If I wanted your clothes, I wouldn't have left them at goodwill.

"Disrespectful" would be telling you that you in particular should continue to use windows or mac, and avoid Linux like the plague.

Do you actually want to run an application that doesn't exist on Linux?

I use a virtual machines for the 2 or 3 times a year I need to use a couple garbage windows-only programs. Usually for configuring some arcane piece of proprietary hardware that people were getting rid of because it is incompatible with everything.

The volcano is very likely causing the thunderstorm. Thunderstorms develop when convective activity pushes hot, moist air to high altitude. The high heat from the volcano very likely induces the convective flow necessary to generate the storm.
