The purpose of the endowment is to fund it in perpetuity, so yes

The Wikimedia Foundation has enough money in its endowment fund to keep the actual service going forever, even if it never got another dime.

It is almost certainly a legal issue, and not their choice, but I am surprised this would not have been explained to you if it is the case. There are states in the US, including the one I am in, where it is explicitly illegal for school staff to use any names or gender references other than the ones provided/approved by the parents in your record, even in private. It is entirely possible they have no choice here.

Not OP, but a thing I am pretty heavily involved in. It depends a lot on the community you’re in and the culture around it, and my experience is that most people who practice kink in a community setting also consider it an integral part of their sexual life, but not exclusively so. There are many that approach it as a connective practice that focuses on power exchange, communication, and sensory exploration as much or more than as a form of purely sexual gratification. The kind of intimacy and connection that you cultivate with mindful, consistent kink, even if not explicitly sexual, often cultivates a safe environment for negotiating and potentially exploring sexual chemistry with a partner if the feeling is mutual.

Generally, it’s considered normal for sexual boundaries or interests to be a part of negotiations when you’re exploring a kinky connection with someone, however it is rarely a deal-breaker in my experience if either partner isn’t interested in that, nor is it often the primary thing being negotiated. I have a few partners that I regularly do kinky things with and also have sex or do sexual things with. Many of the people in my community do consistently integrate kink with sex, but most of what goes on in public or semi-private spaces are non-sexual scenes.

Even if so, nothing short of level 4 plates would have stopped a rifle round with that much energy. Handguns, sure, but he didn’t appear to be wearing a plate carrier.

Don’t even bother with glass. That’s hella old tech for PLA printing. PEI sheet is the only way to go.

“Cache” means space used for disk caching. It’s free to be used for processes as needed, but the system consumes idle RAM until then to speed things up, so it’s technically not “free”, even though it isn’t used by system processes. In Linux, used - cache gives you the actual consumption by processes.

Jet fuel used in commercial planes does not contain lead. Unless you live around a heavily used general aviation airport, your exposure to lead from airplanes is minuscule.

The latter half of this about aviation fuel went off the rails. Much of it is exaggerated or straight up inaccurate.

First off, lead is used in fuel to protect non-hardened valves used in old engines. It is not just an octane booster, and it’s not some giant conspiracy that’s keeping it in use. Modern engines don’t need it, but people aren’t running it just to be dicks. It’s part of the engine design in really old stuff, which is a ton of old aircraft that haven’t been rebuilt and updated to use unleaded fuel. Converting and certifying these old engines for UL is prohibitively expensive for many hobbyist pilots, but on the whole, leaded avgas has been being phased out for years, and it’s becoming less common every day.

Furthermore, airlines do not use leaded fuel because jet fuel does not contain lead. 100LL (100 octane low lead) avgas is used in small, older piston-engine aircraft, but that accounts for an incredibly tiny fraction of aviation fuel consumption, and there are unleaded avgas formulations available for modern piston engines that can use it. While leaded avgas does contribute to lead pollution, its effect is heavily concentrated around small airports with older private aircraft. Avgas is not a significant contributor to lead exposure for the average person.

I think if you can ensure they all thread together without a problem, it doesn’t need to be perfectly clean, but I suspect that will be difficult if there is melted filament in the threads at all
