But in a large SRAM, most of the gates are not switching, at any given time. The cells are mostly just sitting there holding their data. And if cooling it lets you shrink the SRAMs that’s also going to let you reduce the capacitance, so s

Why would anyone panic over DeepSeek R1? It’s cheaper and open, but still not remotely general intelligent. Their breakthroughs can be copied, and probably surpassed by someone else. Could be Meta, could be another company in China. But com

If that kind of stuff is always preferable, the nobody would use C over C++, yet to this day many projects still do. Borrow checking isn’t free. It’s a trade-off. I mean, you could say Rust isn’t a modern language because it doesn’t use gar

I agree that quantum computers that can break classic encryption is not coming any time soon. Maybe not ever As for the Bitcoin market cap. That’s completely meaningless. There’s not $2T of value in Bitcoin. Any cryptocurrency can reach mil

That future will never come. Nuclear power has several fundamental barriers to scaling, and given that the world population is still growing and the demand for energy per person in the developing is growing, those barriers will become an is

There’s some serious false equivalence here. Is Xbox prevented from competing with Nintendo in Japan, under similar conditions as Nintendo competes with Xbox in USA? Are there representatives of the Japanese government sitting within Ninten

I don’t think you’re keeping in mind what these batteries are replacing. Coal power plants and gasoline cars release harmful smoke as part of their regular operation. ICE cars are several times more likely to catch fire than an EV, and cont

Compared to what? For cars fires there have been some articles showing there’s not much difference in the amount toxic stuff in the smoke between EVs and ICE. So batteries aren’t that bad. If we’re talking burning factories I’m sure there

For the booster I think it’s fairly well established that it’s cheaper to reuse it. It’s not that hard on a booster to come down again, and it doesn’t seem like it’s that much work for SpaceX to refurbish their boosters. For the upper stage

But sunlight is wide spectrum, and a lot of the reasons why the efficiency of regular solar panels is low, is that they don’t absorb all of the spectrum equally well. That’s why there’s all this talk of tandem solar cells with perovskites t

But they don’t have energy independence or food security yet, which is kind of a hard requirement for an invasion. There’s not enough rail lines and gas pipelines from Russia to feed them with significant quantities of fossil fuels. Imagine

> If everyone else switches to EVs, where will Norway get the money for its own EVs? This question doesn't even make sense. EVs are already cheaper than ICE cars when it comes to Total Cost of Ownership. There are clear signs that w

Hydrogen and BEV received the same support and benefits in Norway, for many, many years now. BEVs have reached 90%+ market share. Hydrogen cars are all but dead here. Norway is just about a worst case scenario for EVs. People love driving h

Not necessarily. They can have a target margin of X% which is completely reasonable. Then they lower X for the lower RAM options and increase X for the higher RAM options. That way more people can buy your product, as many will be fine with

How far in the future are we talking about? Russia doesn’t have the capacity to transport that much oil by land. It’d take years to build that infrastructure and it’s not even clear that China is at all interested in supporting huge investm

Chinas total population isn’t really that relevant for what their economy will end up looking like. China is essentially a handful of moderately wealthy coastal areas (perhaps comparable to USA in population but still far behind in GDP&#x2F

Why? It’s in the EUs interest to not create horror stories about what happens when a country joins. It makes a lot more sense to make Iceland decide on the timeline for adopting the Euro themselves, so the transition is more likely to be sm

Not 64 bit, it’s 32-bit cortex m33. M33 has, among other things, TrustZone. So there’s some feature, along with developer familiarity and tools that make ARM desirable for an application processor. Mixed architecture doesn’t really cause an

That feels like a very high bar. A really good 500Wh/kg battery would already be completely revolutionary. That’s when you start to unlock practical short range electric flights for instance. It’d probably be enough for all forms of la

It should be said that at that point you don’t have very many charge cycles left after the capacity drops below 80%, and the capacity will drop a lot faster for every charge cycle after that point. I don’t have exact numbers.. based on grap

Obesity causes epigenetic changes in fat cells that make it much harder to stay lean if you’ve been obese before. So it’s not the fault of the drug or the people using them that they balloon back up. The exact same thing happens on diet pro

You can use IKEA trådfri with Philips Hue. It’s a bit annoying to pair but once that’s done it just works, at least it has for me.

What’s the assumption that causes them to find there’s still a market for fossil fuels at all by 2060? I’d be surprised if its share of energy generation doesn’t drop to practically zero. Why would we think it flattens out? With some techno

What are you talking about? I live in Norway, much further north. We all use electric heating. My highest power usage this December was 41kWh in a day. Less than 2kW continuous usage. Yesterday was 25kWh. Yes, we have a heat pump. If you do
