From what I understand the polished limestone is accurate for many pyramids, but the gold pyramidion seems to be more of an edge case on some smaller pyramids.

A gold top wouldn’t even be visible from the ground on a large polished white pyramid.

CarPlay/Android Auto doesn’t require a modem in the car. Your phone already has a modem in it.

That was one of the things that excited me most from the iFixit video; the (LGA?) pins are a separate part that can be replaced as well. Simplifies the motherboard because then there are just flat pads on there, which means they don't need to include the whole array of fancy pins for a second module if it doesn't ship with one.

While I agree with you on the difficulty of cryogenic fuel storage and re-fueling in orbit, the ISS does actually have some of it's own rocket thrusters. They're on the Zvezda module and are re-fuelled by Progress vehicles. Relevant section from the Wikipedia article on Zvezda:

The Service Module has 16 small thrusters as well as two large 3,070-newton (690 lbf) S5.79 thrusters that are 2-axis mounted and can be gimballed 5°. The thrusters are pressure-fed from four tanks with a total capacity of 860 kg. The oxidizer used for the propulsion system is dinitrogen tetroxide and the fuel is UDMH, the supply tanks being pressurised with nitrogen. The two main engines on Zvezda can be used to raise the station's altitude. This was done on 25 April 2007. This was the first time the engines had been fired since Zvezda arrived in 2000.

>10 cutting discs on an angle grinder. So not really reasonably.

Though they do mention that usually bike racks are easier to cut through than that anyways.

I’m not sure I see this one to be honest. As bad as a car-dense city is for everything else, it’s probably the best option if the whole city had to be evacuated.

A large portion of alternate transport is focused within the city (trams, bikes, subways, etc). I suppose at least busses could be re-purposed for evacuation, but it requires a whole lot more organization.

In general, agree with your explanation here, but would disagree on the repairability point. Lots of carbon repair shops will repair carbon parts. Often just needs paint sanded off and additional carbon bonded on. Generally doesn’t bend and deform like metal parts, so the cracked bit can just be cut out and reinforced.

On the other hand the aluminum alloys a lot of car parts and bikes are being made of end up quite difficult to weld and re-heat-treat in practice, so no easier than carbon.

Weren’t each of the pyramids built by one pharaoh? Then each would be about one generation of work only?

I think Rivian has a lot of potential to take over as the next big dedicated EV manufacturer, after people are turned off from Tesla. Hopefully this model launch goes well for them.

Minor correction: you have the wrong community address under the third item in your “For right now” section. Should be !196@lemmy.world I think.

Judging by the average altitude above current sea level of the Netherlands, they may BE the climate refugees.

In the PinkBike video, they mentioned that the full-face helmets didn’t perform as well in at least the rotational impact tests due to their higher mass and moment of angular momentum.

I think it always ends up being a bit of a trade-off, depending on the types of riding and impacts expected. In a low-speed impact to the side of the head a regular bicycle helmet will often do better than a big heavy motorcycle one. Obviously the opposite is true for a motorcycle crash at 80 km/h.

Hyped for this!

Wonder why they decided to announce both at the same time though. Seems like a bit of an odd choice.

Quick summary seems to be that they’re using it to monitor the stars that Webb is seeing planets pass in front of. To better model that stars behaviour with prolonged observation. To better understand whether signals that look like water and methane are really from the passing planet, or just from changes in the star’s activity over time.

Interior blinds are mentioned in the video: basically since they’re behind the glass the energy is still getting in and green-housing a bit. Blinds heating up is heat inside the room. Also block the view out, which awnings don’t.
