Sounds like they fucked up training the AI then. For a user it doesn’t matter whether the AI is designed poorly or trained poorly, it’s behaving poorly.

Probably way better and way more expensive.

A reasonable length survey will never “paint a full picture”. Maybe what they’re trying to show is that there are a lot more people who value walkability more than is currently assumed. In most of the US you can either chose a super high density walkable area in a condo tower or a house in a car based suburb. It’s possible to design neighborhoods that are walkable and can provide a reasonable amount of private outdoor space, and what this shows is people would be willing to pay for it!

Yeah the current challenge with searching is if no one has subscribed to a magazine or user on another instance, you have to search the exact name@domain to get it to show up. Ideally Kbin instances would implement a user bot that subscribes to all the users and communities it can scrape from all federated instances until this search limitation is fixed.

I’m a sucker for any connector that has a nice solid spring load mechanism that pops into place when properly connected. It should sound like a movie sound effect of a gun being reloaded.

I’ve also used some really nice quick release steering wheels, like on race cars or racing sims, where they have a spline connector with a tight fit and a good spring load.

The carbon free rock is replacing limestone in the manufacturing process, not the sand. Sand is added to cement, along with rocks and other aggregates, to form concrete.

From what I can tell, the way this might be bad is that the carbon free rock may not exist in significant quantity. If it does, it will be mined in the same way as limestone, so that’s just a wash not a bad thing. If the rock they need doesn’t really exist they have to buy it from someone else who makes it from readily available materials. In that case, it could be green washing, where the company can claim “our process doesn’t release much carbon compared to the traditional process” but in reality the total carbon released to create the cement - from mining to processing to pouring - could be similar.

I never really liked Calibri at any font size above like 14 pt maybe? Hopefully this new one is better than Arial and I can switch all my PowerPoints over to it.

Tbh you might be able to come back go pocket casts. They added a bunch of functionality back over time. Can’t remember what it used to be like anymore, but it works for me.

I have a free account and do have access to the filters. You can filter by podcast, started/not started, duration, etc. It may still not work for your needs though.

On one had we’ve got links to the department of energy and to Wikipedia. And just some hand waving on the other hand.

If we’re talking approaching fundamental limits, Hydrogen fuel cell is not a great comparison. A high pressure tank can only get so light, even with linerless ultra high strength carbon fiber pressure vessels, the mass of the vessel is maybe 6-10x the mass of the hydrogen it carries. To increase specific energy there you need to go to cryogenics which is a whole technology leap and has its own set of challenges.

Battery tech has been improving more than you have seen, clearly. Since '08, lithium batteries have increased energy density by 8x (https://www.energy.gov/eere/vehicles/articles/fotw-1234-april-18-2022-volumetric-energy-density-lithium-ion-batteries). The best LiPo batteries are around 0.9MJ/kg right now, but there’s no fundamental reason a battery couldn’t achieve 9MJ/kg. Lithium-air batteries could theoretically achieve way higher energy density than that even (https://en.m.wikipedia.org/wiki/Lithium%E2%80%93air_battery), and have already been demonstrated in a lab to achieve more than 5x what current commercial automotive batteries are doing.

I think the point that is counter to yours is that we are nowhere near the fundamental limits of energy density for batteries. It’s probable we are near a fundamental limit for LiPo, but the point is that battery tech improves by changing technologies/chemistries. BEVs couldn’t exist at all when the best rechargeable battery tech was lead-acid, but were enabled by LiPo. Theres most likely a type of battery you can’t even imagine that has yet to be invented that could store >10x or more energy than current LiPo per unit cost or mass.

Good luck electing anyone not in the two party system. I think there’s 1 or 2 independent senators and no independent representatives. You need to change the rules of the game, cause like it or not were all playing the game. And not voting or voting 3rd party when they’re polling at 1% is just giving an extra vote to someone who disagrees with you.

Dude what the hell? You posted publicly in a public comment thread and are mad when the person you’re talking about responded? You know this could happen on reddit too right? Creators are people too, you absolute dick.

I’m seeing a lot of misconceptions in the replies. You have it mainly right from a very high level.

The reason why prepreg “expires” is simply that the resin system is mixed before being impregnated into the fibers, so it starts the curing reaction immediately. These resin systems are usually designed to cure properly at high temperatures, typically 250-400F depending on end-use, but they’ll still slowly react at lower temperatures. To further slow the reaction, prepreg is kept frozen. Prepreg also has two types of expirations: “shelf life” and “out life”. Shelf life is how long it can last frozen. Out life is how long it can last at room temp.

Theres a few issues that can happen when using expired prepreg. It can be harder to laminate since it will be too stiff and not as sticky. It won’t cure correctly causing failures in the resin.

Expired prepreg can be recertified by testing the material for those types of failures. Check if the prepreg can fold over a certain radius and stick to a certain angle without sliding off. Cure a sample and test it to see if cured properly.

PocketCasts was pretty much perfect for me for a long time and recently (past couple years maybe?) they did a big update which made it noticeably worse. I tried a few other apps and they had even bigger issues. I’m still using PocketCasts and they’ve fixed some of what they messed up but it isn’t perfect.

They have a good library of podcasts built in but also allow you to add custom rss feeds for any smaller shows they don’t have or if you have private feeds from patreon or elsewhere.
