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.

What’s the point if they still have AMD, Intel, Nvidia, Qualcomm, etc. chips on them?

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.

Having multiple, semisolated compartments in a Hyperloop train is entirely reasonable. There’s definitely room in a traincar for the occupants of a compartment that’s on fire to move to another compartment for emergency purposes.

Evacuation points would be defined every so often (say every few miles) such that the train could come to an emergency stop within one, seal doors on each side and let air in. This would take a few minutes, but so does landing a plane or stopping a high speed train.

Bottom line is that fire safety is, to me at least, an entirely solvable problem. The biggest problem with Hyperloop, I think, is that given the materials for the vacuum sealed tube and the energy required to hold that vacuum, it is just so unlikely to be more efficient than a maglev. For medium distance travel, even standard high speed rail is good enough to replace planes, so we don’t need the extra speed for ~500 mile distances. For longer distances where high speed rail is super slow or impossible, such as across continents and oceans the cost of building the vacuum tube will be so costly that it would take something like a complete ban of non-renewable fuels in aircraft for it to be a consideration. Even then, I think it could end up being cheaper to develop and use renewable fuels for aircraft.

It is much harder for fire to exist without air. There are some self oxidizing fires, but it should be relatively easy to avoid those materials. For fires inside the vehicle, there are some existing fire protection protocols that could be followed. There have been fires on the International Space Station and they couldn’t exactly run outside either.

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.

There’s nothing formal stopping the SC from doing anything, but courts are generally limited to ruling on the controversy in front of them in as narrow a way as practically possible. I haven’t read any analysis on this ruling, but just from the little I have seen, it looks like they ruled that the HEROES Act didn’t grant the federal government the ability to forgive the loans in the way they were attempting.

Biden could try using an authority from a different law or creating a different set of rules by which the loans may be forgiven.

My non-lawyer prediction is that if Biden tries again, the SC will find a new reason to stop it and will make a bigger ruling that takes more power away from federal agencies to make decisions. They’ve already been doing this with environmental and health decisions, and I’m sure other agencies have been impacted too.

The crazy thing is it isn’t even as good now that they fucked over and lost their chili source. The new chilis just aren’t as good.

I’ve got a beard but I wear contacts and would never use an actual picture of myself on a public forum like this.

Well it seems I was wrong, you’re still here and it seems like you are genuinely interested in the way this all works. However, I hope you can see how the phrasing “oh well, back to reddit” could be taken perhaps not quite how you may have intended it.

It is true that this is not identical to reddit. In fact, I think most of us here hope it will become something better than reddit. Keeping the best parts, excising the worst. Adding new features and interacting better with the wider internet.

I hope that as we get more users, the benefits of instances emerge, but right now there’s just not quite enough activity to make it work too well. But the vibe I’m getting from a lot of your comments (I haven’t read them all, so I could be off-base) is that you are looking for justification for not liking something about this place, rather than having an open mind.

I don’t understand a small thing about this new place, better just leave.

Blocking isn’t defederating. The instance controls federation, but blocking is on a user basis.

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.
