I have begun to write a page (by hand) summarizing my thoughts after reading a book, and put it in the start of it. That was a tip I saw on HN some time ago.

A number of companies only announce job openings on LinkedIn, and if you are looking for a job (as I am) you would handicap yourself by not having a profile there. HR departments around the World are infatuated with LinkedIn, unfortunately.

My strategy is to give LinkedIn a minimum of information, use it for job search, and filter away most of their emails.

I look forward to the day where I can close down my LinkdIn account. But until then I have to put up with it.

When I wrote Turing Machine, I was thinking about the classical determinstic Turing Machine.

Im not super knowledgable about Quantum Turing Machines, but as far as I know, they dont do better than the classical deterministic Turing Machines when we are talking about computability.

Those quantum processes are interesting. Take the random numbers generated from radioactive decay. They are (after some cleanup) truly random. That is what we think. But how could we tell the difference from pseudorandom numbers, generated by a sufficiently advanced algorithm? We couldnt. So particles could simply be Turing Machines running sufficiently advanced algorithms that we cant reverse engineer. If so, quantum mechanics is computable even if we cant compute it.

(Particles being TMs doesnt mean they are FAs with an infinite tape, but that they are computationally equivalent to TMs.)

My problem was not using apps, but the other stuff. I did as I was used to, stubbornly bumbling around, feeling sure I would run into the solution. But I never did. I had to look up instructions, several times. That was never necessary with my old iPhone.

That is, until two weeks ago when I got my new iPhone. I had to, the old one couldnt upgrade to the newest iOS.

I feel ashamed to admit, that I had one or two days of extreme frustration just learning to do basic stuff. It was not about the shape of icons, but more along the lines of what you write. Swiping patterns, button press sequences, and the time you should hold down a button. It is ridiculous.

Some of the blame is on me for not being mobile phone savvy, but it is indisputable that the UX has deterioted significantly. I suspect it will just get worse going forward.

It was introduced in 1968, when Denmark was a high-trust society. It was used as a sort of password and key for looking up your information. If you wanted to create a bank account, you told them your SSN. If you wanted to buy a car, you told them your SSN. If you had any contact with the authorities, you told them your SSN. And so on.

The usage has changed, but not that much. So today, when trust in Danish society is not as high, the system falls short. Identity theft. Privacy. Scamming. They have to be detected and stopped by other means.

The proper path forwards would be to radically change the system (or the society).

What is good is that he is a wrench, that throws itself in the works repeatedly. This is a healthy thing to have.

For small groups of servers, with limited egress communication, it might nevertheless make sense. And then go for it, by all means. As a general replacement for DNS, not likely.

It is hard to see how Ansible should be simpler than DNS. Maybe if you have worked with Ansible and not DNS, you might think so.

The MitID design is strange, but in this regard it is well done.

For those companies that have offices in both countries, and for which the synchronicity matters, it is not that difficult to just have special office hours.

It is sad that FreeCAD gets all the attention. If Solvespace had some of it, and the development time following from it, it could get improvements and some of the cool stuff in their pipeline. That would IMO make it a much better CAD program than FreeCAD could ever become.

But you are also right that this is not the only way they work. With the XZ Utils backdoor (2024), we normal nerds got an interesting glimpse into how they create a zero-day. It was luckily discovered by an american developer not looking for zero-days, just debugging a performance problem.

But even if the authority was a private company, I think it would be an improvement compared to the current situation. In this situation your personal information would be held by this one company, and not whatever provider that needs to verify your age. Also, you would be able to use the commitments, that this private authority gave you, without any coordination afterwards. The authority would not know about your transactions.
