Ok a few things:

Batteries don’t need “a few sparks” to catch fire. They will generate plenty of heat if punctured and self-ignite.

You don’t pour water on a grease fire because grease floats and it will spill out of your pot and catch the rest of your kitchen on fire. Also the water will boil and splatter oil everywhere.

Also pouring water on a battery fire is the preferred way to put it out. Many of the chemicals in the battery will release oxygen when heated, so the best way to put it out is to cool it down as much as possible by dousing it with a shitload of water. It isn’t always possible to apply enough water to the core of the fire which is why they are hard to put out. Sand won’t do anything because the fire is self-oxidizing.

Yes lithium metal reacts with water, but that’s not what makes batteries hard to put out.

The problem is not with public transportation, the problem is that the area surrounding this highway was designed so that more cars and more lanes were the only possible solution.

Cars create problems that only cars can solve.

Edit: and to add more context: those 50 different locations are all separated by massive mandatory parking lots which make them miles apart from each other when they could likely all be contained in the same building in front of a single bus stop.

She was actually made up to be pretty ugly for most of the first season, but they hotted her up at the end as the result of some magic shit.

I watched it once four years ago, so don’t remember the details.

I was once motivated to work out by Amizon Subscribe and Save.

I had a subscription to protein shake powder, and I only let myself drink it after working out. If I skipped too many days, I’d still have some when the next shipment arrived, and I hate wasting food.

While many athletes are millionaires, many others make a reasonable salary for the 5-10 years that their knees still work and then “retire” with no transferable skills, broken bodies, and scrambled eggs for brains.

I don’t get it. For the average consumer, EVs as they exist right now are fine. Charging is generally 20 mins every 2-3 hours and only on road trips. Charging an EV at home is a trivial technical challenge. I understand that there aren’t chargers on street corners, but vehicles are rarely parked more than 20 feet from some kind of electrical service.

The idea of shipping liquid fuel in trucks and dispensing it out of hoses at special fuel stores is just silly. Rolling out that kind of infrastructure is unnecessary, and hydrogen has already showed that it doesn’t work. We only did it with gasoline because there was no other way.

I can see liquid fuel being useful in certain applications, but for the typical consumer, BEVs are the way to go.

I picked up a low pressure sodium lamp and am working on a Halloween demonstration. I’m hoping to make a display that appears one way under normal light, but looks totally different under the monochromatic 589nm sodium vapor light.

So basically, I’m looking to generate a color wheel where I pick a shade of gray and get a list of colors that would look that gray under sodium vapor light.

…I feel like there must be a Python library for thing or something…

Update: thanks all for the very helpful advice! I think it’s really special that not one of you dunked on my DM. You all seem very supportive of a broad range of play styles and that’s a sign of a very healthy community.

I reached out to one of the more experienced players in our party, and I’ll be pinging our DM at some point over the next week. I’ll see if we can switch gears or if not leave peaceably. Thanks again.

Recently got into DND. Watched two seasons of Dimension 20 and loved them. A friend of mine offered to try DMing for our friend group. We meet every two weeks for 3-4 hours. We're playing Pathfinder using the Foundry online interface so we can play remotely.

Apologize if I mess up any terminology, I'm new.

I am two hours into this week's game right now (in another tab), and I'm so fucking bored. We're in some underground tunnel system, and just getting bombarded by completely arbitrary enemies.

Last round we spent three hours fighting a mimic and a gelatinous cube, and there was no explanation for why they were even in the cave in the first place. We haven't had a conversation with an NPC in three sessions. End of the round we come across some weird tunnel system with giant moths on one side and giant larvae on the other. No explanation for why they're there. We start coming up with a plan on how to kill them so we can get the loot they're guarding, but it was the end of the session.

This week, right when we start and try to do something about the moths, we get attacked by morlocks that came up the tunnel behind us, fight them for an hour and a half, and the remaining ones just run off. So now we're finally dealing with the moths.

Anyway, we're doing this on a giant map in Foundry. Nothing is theater of the mind. It's all very literal, and it feels like I'm playing an incredibly slow PC game just sliding my token down tunnels. Nobody is really roleplaying. We rarely get any details during our battles beyond "they look really hurt."

I don't expect anybody I know to be at the level of Brennan or whatever at DMing, but there is just no entertainment value for what we're doing here, we're constantly in combat, none of my skills are useful (because we're just fighting mindless monsters), and it's like a solid 10 minutes between my turns.

Like end of last round, I floated the idea of trying to mount and tame one of the moths (I'm a halfling, and they're big), and my DM just said "I mean, that's pretty dangerous. If you're ok rolling a new character, you can try it." Like geez, sorry for trying to make it interesting. At least give me an in-game reason for why I shouldn't do it.

I really want to quit. Any advice?

In the original Sims, I was 11, and didn’t realize skills improvement would get your sims better jobs.

My sims were all top ranked in the military because that was the best job that required no skills.

What I love so much about the whole “turning the water off when you brush your teeth” debate is how everyone is basically telling on themselves.

The ADA recommends brushing your teeth for two minutes. Do you think anybody sits there and lets the water wash down the drain for two whole minutes? Or more likely does everyone have terrible dental hygiene?

Everyone knows the tale of Brand X getting bought out by some faceless global conglomerate and going to shit, but does the opposite ever happen?

Maybe specific, but if you do any DIY housework, get an endocscope. Baiscally, a 10 foot long flexible wire with a camera and light at the end. Uses your phone as a screen. Can be had for <$50. So many of my house projects would have been impossible without it. Also good for finding stuff under the couch.

Recently started using a LightPhone II when out of the house, and I found the article captured my current experience pretty well. It’s not so bad to be bored sometimes.
