A linked list of each authoritative name in the zone. Not a list of zones. That's for offline signing. For online signing you can do different things. But the point is, and that's …

The problem here is that computing three 3 NSEC3 records as you might need to return an NXDOMAIN was considered too expensive. It's just a choice to reduce their costs while increa…

At the time it was well known that messing around with NXDOMAIN would cause problems. But some companies wanted to do it anyhow. The solution is simple, if you want to use this DMA…

I think it is a marketing failure. The web was mentioned before, but ARM, Wifi, Bluetooth, the CD, all European inventions. There are core parts of the internet that are completely…

The situation in Europe is even more crazy. The US needs the bases in Europe to project power in the Middle East. If every country in Europe would ask the US to leave then the US w…

I think what matters is the size of (for example) the German economy with and without the EU. Futhermore, what matter is the amount of tax collected by the EU. Energy subsidy is no…

Why not? If the increase in cake size is bigger than the subsidies then it can be a net win, even for the people paying the subsidies. It also ignores the fact that absent the EU, …

The Netherlands recognized the problems with the last-in-first-out system and requires that after a reorganization, the statistical distribution remains the same. How well that wor…

If DNSSEC is part of your security model, you want local validation. Not relying on third party resolver that you don't have a contract with. Beyond that, DNS has the AD bit. If yo…

I'd say that if the original Ada was introduced at the same time as Rust development started then people would pick Rust. Ada is also a product of its time would have to be moderni…

I think that is not correct. One of the big differences between K&R C and C89 is the introduction of function prototypes. Strong typing was certainly considered positive for compil…

I'd say that is even more so with Rust and Rust got popular in a very short amount of time.

The article gives another reason "A second answer is aesthetic. Ada's syntax is verbose in a way that programmers with a background in C find unpleasant. if X then Y; end if; inste…

I agree. There are quite a few places where they author claims that Ada had a concept first and some language got the same concept later, but the two concepts are different enough …

The 286 worked perfectly fine. If you take a 16-bit unix and you run it on a 286 with enough memory then it runs fine. Where it went wrong is in two areas: 1) as far as I know the …

I think from the price people also expect a similar performance boost as going from 386 to 486. What made Pentium also confusing is that during this time Intel introduced PCI. From…

We can assume that organizations like NSA have collected a huge amount of traffic that is protected by RSA or EC. So they well have plenty of use for those quantum computers.

It is the paradox of PQC: from a classical security point of view PQC cannot be trusted (except for hash-based algorithms which are not very practical). So to get something we can …

The thing is, producing the right isotopes of uranium is mostly a linear process. It goes faster as you scale up of course, but each day a reactor produces a given amount. If you d…

What surprises me is how non-linear this argument is. For a classical attack on, for example RSA, it is very easy to a factor an 8-bit composite. It is a bit harder to factor a 64-…

If we are looking at the RSA factoring challenge ( https://en.wikipedia.org/wiki/RSA_Factoring_Challenge ) then 768 bits is done. Breaking RSA 1024 is assumed to be possible but ha…

The problem is that these laws tend to escalate. Once a government starts regulating, it doesn't stop. It is also the wrong model. Instead of creating child-safe devices, just like…

There is a huge attack surface for this. For example, kid manages to buy an old phone. Resets the phone and creates an account. Kid buys something like a Pi 3 manages to get a regu…

The problem with TAI is that the rest of the world uses UTC. So you can use TAI on a small island and then you have to convert to and from UTC. My hobby kernel is based on TAI inte…

Which means that time changes slowly enough that we don't notice. At some point everybody goes work half an hour earlier because it makes sense. Schools start earlier, shops open e…
