As someone from Germany I'm sometimes surprised what stereotypes exist outside Germany about it. I can assure you standardizing things is not something Germany is good at.

> The thing is that Germany was planning on significantly increasing their gas demand by building many gas reactors [1] to work in tandem with renewables. I wanted to explain what's wrong with this statement, because that's sim

Was also the first thing that I noted. They're comparing fictional nuclear prices with real renewable prices. One more thing though that makes this calculation even more ridiculous: They're comparing today's wind+solar prices

There's no need for one. How NIST chose algorithms in the past was done in quite diverse ways. Sometimes they merely said "this is a standard" and people could comment and the comments were ignored. This is basically what hap

I've been following this space for a while and this is a good question, but I think the answer is really a "ranges from 10 years to never". There's a lot of investment currently in the quantum computer space (+ a lot of

You're converting Sea water to water (desalination) and then do electrolysis to get H2. You need to get CO2 from somewhere, you can use Direct Air Capture technology to get it from the air. Then you do this: https://en.wikip

We already have all the ingredients to turn CO2+H2 into Methanol without an intermediate step turning it into Methane. There are already a few production plants, e.g. one by Carbon Recycling International. It's not super efficient, but

HTTP GET requests are supposed to be idempotent, meaning that when you call an URL twice it should not lead to any different result compared to calling it once. This is part of the HTTP standard. So while I think what Outlook does here is w

In crypto code you often have conventions to name a certain value with a letter. E.g. RSA public keys consist of the values N, e, private keys also have d, p, q etc. One may argue whether a, b and m are as "commonly known" for mod

There is a lot of circumstancial evidence that supports the backdoor story, e.g. the extended random extension or the events around RSA Inc. and Juniper. I mean... it's a question what would qualify as prooof (a copy of "here are

Just skimmed over it, but this seems like an odd statement: "The problem of the algorithm was quickly handled. NIST, which had approved[17] Dual_EC_DRBG as a FIPS, immediately responded by recommending that the algorithm not be used an

Sure we can, but a) all processes synthesizing hydrocarbons start with hydrogen, so you'll need cheap green hydrogen to begin with, and b) it takes a lot of energy.

How do you make ammonia with a battery? The target use case for hydrogen isn't the cases where you can use a battery. It's all the places where that doesn't work.

In Germany pretty much every dentist will recommend you a "profesionelle Zahnreinigung" (professional tooth cleaning), and if you lookup what studies exist to show that it does any good, there's only one study that's bas

I find it really strange where some privacy debates have gone wrong, and this is a perfect example. It's basically a form of "don't trust them, better trust us, also we're in a country with better privacy laws". Whi

There's been an EU funded research project that did some projections on the electricity needed for e-fuels. See the graphic on page 44: https://www.fch.europa.eu/sites/default/files/FCH%20Docs/202...

This may sound plausible at first, but if you've watched these kinds of things for a while there's an entirely plausible other explanation. Everyone wants to have their little special case feature in, and nobody says "No!&quo

I would really want a tool that is a kinda swiss army knife of TLS functionality, but usable. Yet such a tool to my knowledge does not exist. E.g. something like "check the OCSP for this certificate". This should be a simple comma

I've spend a few minutes on your page, yet I couldn't answer the following questions: * Do you already have a working editor I could test or is this merely an announcement? * Is this an open source project or a proprietary product

No, because a technology once seen as promising that completely failed to deliver its promises and is only used in very small scales today is irrelevant for the debate.

That hasn't been true for a while. Wind turbine towers are large enough these days that they can absolutely be built in a forest, and this is often happening. It's also crucial, because you simply need that space if you want to bu

There's no ultimate solution, but there are a few things being done in common DNS servers that can mitigate the issue: * Large answers like ANY queries or large DNSSEC records should either be not supported or only supported via TCP (s

It seems somewhat suspicious that the benchmarks don't compare to zstd. It's not entirely clear to me what the selling point is. "Better than bzip2" isn't exactly a convincing sales pitch given bzip2 is mostly of hi

You should be aware that Microsoft's SMTP servers parse the mime structure of the mails and restructure it in a non-standard way. I have no idea why, but for example this breaks PGP signatures.

It should be noted that AccuWeather is a very problematic source when it comes to any topic related to climate change. They were spreading outright climate denial in the past and have spread misinformation downplaying climate change since:

This is a project I've been working on for the past months. I figured out there's no easy tool to check cryptographic keys for past vulnerabilities like the Debian OpenSSL bug. The tools from the time the vulns were found are ofte
