I’m wondering if the software world has something to learn from digital design here (for once), where there’s a huge emphasis on code coverage collection. You really shouldn’t care how a function is tested. That there exists a test for that

I made a point to follow Solid Energy Systems many years ago, to see how one such battery technology panned out. They went dark in public media for a while. But they’ve recently gotten more publicity again. Turns out they got some industria

Why do you need such long lifespan for grid storage? It’ll be much easier to service and change out modules in a grid storage plant than in a car. Most likely, when recycling tech is more widespread and efficient, you’ll want to recycle the

“Inherently safer than kerosene and synfuels” - No way. Or at least: I don’t think we truly know yet, until they’ve flown for a few years. I used to think hydrogen was extremely safe. It’s super light right, so it should quickly vent away i

I suspect solar isn’t cheap enough yet for it to make sense. Probably doesn’t help reduce the need for batteries either in the north, since you won’t get significantly more range from it in winter. Every solar panel made should be installed

That’s like calling it xenophobic to refuse to travel to Somalia, pointing to an article about some random violent incident in USA and saying there’s violence everywhere. Chinese paper mills is on a completely different level, and heightene

Been discussed on hacker news before. I think it’s good to highlight the presence of PFAS in straws, but I don’t think the conclusion is that paper straws are bad. I seriously doubt that it contributes to significantly more PFAS in our body

To me it doesn’t seem that paper straws is about the resource consumption or oil used or anything like that. I think you have completely misunderstood the purpose. Even with the order of magnitude increase in resources used it’s still insig

I think you have it completely backwards. Apple aren’t necessarily that concerned with selling the most phones. They want to sell the most expensive phones with the highest margins, and still sell quite a lot. How do you get people to pay a

The original Doom game is meant to be played with non 1:1 pixel ratio.. so some modern ports don’t actually look quite right.

The idea that RAM requirements are going up so much all the time doesn’t seem to match reality if you ask me. The fact that I’m still getting by totally fine with an old 8GB on my old laptop is frankly speaking insane. It’s from 2015. Back

People don’t understand the grid energy storage market. Some think it’s only about storing as much energy as possible over as much time as possible. That’s not the full picture. Response time and ability to handle several cycles a day is al

I suggest calling it Xitter. (Pronounced with the Chinese pinyin “X”, so like “shitter”). It’s a good compromise.

Yeah I used to be conserved about blue light too, but it just doesn’t make any sense. Like the article mentions the amount of blue light we get with regular daylight is orders of magnitude more than anything we get from a screen. The light

I think it's pretty clear by this point that it's like an extreme slow motion train crash. In a free economy China would probably have had a proper crash and perhaps even a rebound by now. But China is doing everything that can to

If you want to leave Taiwan in the case China invades, the right time is when China makes actual preperations for an invasion. For China to execute an invasion, or even just a blockade, requires a lot of preperations that will be easily vis

Is it a mistake if that's all you need? I'm kind of on the side of avoiding ORM unless you have a clear need for it. But I've seen projects where they are very valuable. If you mainly want to register, update and delete a bun

LK99 probably isn’t a superconductor. But nobody should watch Thunderf00ts take on this.. or anything. His videos are low effort, low quality and full of basic flaws.. you’ll probably be more misinformed going out of it. I feel like some Yo

I think Helion is most promising for two reasons. 1. Even if the more traditional fusion power plants manage to generate the plasma itself in a device that’s not too expensive (big if) it seems that just the heat exchange mechanism itself

This is such a weird question. In most cases we never buy directly from the company that makes the product. And in the cases where we often do, like with Apple, they sell with high margins in part to allow third party shops to have enough m

Yeah, interesting point. The problem for an AI trying to eliminate other AIs is that it can't possibly know what other intelligences are out there. What if the NSA has a secret super-effecient ASI monitoring the internet for malicious

The id software source code gets increasingly cleaner for each game I think. I've read the Doom source code and Quake II's. I remember Quake II being very clean and elegant. Doom is not quite there. It's fairly well organized

Why do you think it takes a lot of energy to keep the battery in a usable state? It’ll take quite a lot of energy to get to that state.. but the energy it takes to keep it there is not just a function of the temperature. It’s a function o

I’m inclined to agree. But to play the devils advocate: - Some long range ferries are already running on hydrogen. I’m not sure how much hydrogen will be used in ships in general, but for medium range it seems that hydrogen could be a good

If phone makers feel a need to change charging port now, it’ll likely be to go all-wireless. If wireless charging ends up nearly as fast/efficient as USB what’s the point of USB? (for devices that don’t need super fast data transfer) E
