oss-security gets relatively little use? You must know another oss-security. The one I'm subscribed to is very much alive and an important source of information for me.

There are reasons browsers do things the way they do. Experience and user studies have shown that users have a hard time decoding what error messages mean. "This certificate is expired, but only for a little while" isn't mean

My best guess would be some kind of netapp product, as we saw some self-signed certs on hosts that identified as netapp. But netapp didn't answer, and we got either no or no useful feedback from any of the certificate owners. So we end

My prediction would be that it won't become mainstream. Even if it will be practically possible to build quantum computers for average users (given they currently rely on complex physical experiments, one can doubt that), there's

I would take this with a very huge grain of salt. The only source seems to be a fringe right-wing news webpage (Apollo News) citing from an internal paper (which, it sounds to me, is just a vague proposal from a media oversight body). I hav

Historic bit: in the late 90s/early 2000s there was a bit of a trend - and quite some tension - of demoscene parties getting taken over by LAN parties. I believe the Gathering used to be a demoscene party, but completely transformed in

As far as cloud service servers are concerned, I don't think ARM CPUs have any meaningful marketshare, right? You could start running things on ARM, but, almost certainly, that comes with a lot of extra friction. (Not saying that isn&#

I think this one is among the most significant findings: https://factorable.net/ I also believe there were some android ASLR issues based on the same weakness (i.e., low early boot-time entropy). But this is all quite old,

Making hydrogen from seawater is not an actual problem that needs solving. The problem with hydrogen electrolysis is its energy requirements to split water. The energy requirements for the desalination of water before that is a rounding err

I know quite a bit about PKI and X.509, and I can tell you that much: the overlap with how DNSSEC works is limited.

Buy a pack of 20x500mg (just checked, common size in Germany), take 2-3 every half hour for a while. Sure, that's extreme. But if you're unaware of the risks, you feel sick, and you believe it's helping you. I mean, people ar

Well... There's a long history of people trying to build software that detects bad software. It's known as Antivirus software. It doesn't work very well, because you're up against fundamental truths of computational theo

Your understanding is entirely wrong. Most hydrogen fueling stations receive it from the next steam reformer, which will make it from fossil gas.

If the rest of the world wants to still have an industry once we finally decide to seriously use green technology, they should quickly catch up to China - if that's still possible. While China is still very reliant on fossil-fuels, and

That can't be true, right? I mean, Google broke Adblockers in Chrome to prevent this very issue. And it had absolutely nothing to do with Google's Ad business. So it's completely impossible that such malicious extensions stil

Okay, story time: back in 2018, the German government's foreign ministry was hacked. At the time, a colleague of mine (we were both working for the German IT news magazine Golem) found a web page by a government-associated university t

I'm certainly a lay person here, so take this with a grain of salt. But my understanding is that this is part of the problem, or more the issue that people criticize. I think it's largely uncontroversial that the math in string th

True, but the same is true for therapy. Finding a good therapist isn't easy, and having depression certainly doesn't make it easier.

Where would that come from? It's not that we have some large untapped Oxygen or Nitrogen source laying around that is not part of the atmosphere.

They don't, and they can't cheat physical realities either. Plants only filter out very small amounts of CO2 from the air over relatively long timeframes. That's why crop-based biofuels require such enormous amounts of space.
