Let's just put it like this: Most "simple" explanations of RSA are wrong. The "advantage" of ECC is that there are no "simple" explanations of ECC, because there's no comic version of ECC that is inse

There's been pretty much one major factor that made wind turbines more efficient: They got bigger. And it doesn't look like this trend is going to stop any time soon. Nobody wants your tiny wind turbine blades from 20 years ago, b

No conspiracy needed. HTTPS was already there and working more or less automatically, you just had to make it the default. E-Mail end-to-end encryption is inherently more complicated to make work, as you need to put the user in charge of ke

If you think about it what Google did was actually quite smart. By forcing HSTS for .dev they broke setups of people who hijacked a domain name they didn't own and that wasn't made for that purpose (and, as others pointed out, the

I don't think awareness only has any reasonable track record and I would always prefer a technical control if there is one. But I have a hard time seeing any alternative here. I don't think the idea that you can give people access

It's actually even worse. The direct emissions are 7%, the whole are 12%. That includes things like the footprint electricity that steelmaking uses. I used the lower 7% number in that article, because that's the emissions one ta

Sadoway is one of the founders of Boston Metal. Boston Metal is mentioned later in the article. It is also an iron oxide electrolysis technology, but a quite different one (high temperature vs. low temperature).

It's a not so well guarded secret that the claims by many linux distributions that they support old systems with security fixes for many years are not really true. The number of security flaws constantly found and fixed is just too lar

The main energy input for meat from animals is the sunlight shining on the plants that the animals eat. The efficiency of that is utterly terrible. That's also the reason why any form of bioenergy from crops has such huge landuse requi

Just a matter of concentration. 80% of 100g is more than 40% of 100g. It's that simple.

I've seen the bugs in Gentoo, so I am aware that this is annoying (and some of them I'm responsible to fix), but I think it's a good thing this is finally being cleaned up. The issue here is that functions are called without

With a VPN your origin and destination are visible to your VPN provider. You're just moving the point where your metadata can be grabbed. I don't particularly trust my ISP, but I don't see a reason to trust any VPN provider a

The fact that NordVPN needs its own library should already be seen as a red flag. If you need a VPN at all (which you usually don't) then you should use something that works with widely used and tested protocols. That was historically

Given these DNS poisoning attacks come up every now and then, I have a question, and maybe someone here can answer: My understanding is that this is purely an UDP problem. So... why not just say we'll deprecate DNS over UDP at least fo

So many questions unanswered: They remove CO2? How? Direct air capture tech isn't exactly trivial. How much does that weight and how much does that increase the energy consumption? And most important of all: What do they do with the CO

I'm all for reducing plastics, but some of your ideas are quite naive. Like replacing plastics with glas - I mean, you can do that, but glas isn't exactly an environmentally friendly material. Glas making uses a lot of fossil gas,

It's probably neither a good or a bad thing, it's just a "we found something that may guide our future understanding of how mRNA vaccines work". Sounds like basic research that has no direct implications.

It is a lot cheaper to build transmission lines compared to providing storage. In the future the vast majority of electricity will come from wind and solar. If production does not match consumption then it is almost always the best option t
