Greenland is not part of Europe. But they are part of "Rigsfællesskabet" (The Kingdom of Denmark). So part of Denmark but with a high degree of autonomy. Regarding "European values", I think they are just Western values

That is a puzzle thing. The word cube is used very loosely. Douglas Hofstadter wrote about it back when Rubiks Cube was still new. In this case it is a stretch, but the Rubiks Cube inspiration is so clear, that I think it sort of makes sens

I dont think those fonts, linked to in the article, are going to make any significant difference. But I really like the creativity behind them.

I agree, and the very low price of used books that have writing in them, suggests that this is how people feel in general. I have begun to write a page (by hand) summarizing my thoughts after reading a book, and put it in the start of it. T

I basically agree with you, and I have a profile on LinkedIn. 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

Yes I know. 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 Tur

Both P and NP are computable. That is, a Turing machine can compute both of them. Those quantum processes are interesting. Take the random numbers generated from radioactive decay. They are (after some cleanup) truly random. That is what we

I dont know what to say. I relate a personal experience. Yours was different. Good for you. 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.

Im an iPhone user. I want it to take as little space as possible physically and mentally, and try to use it as little as possible. My experience has been that it was easy learning to use it by just bumbling around. That is, until two weeks

I think what is much more important, is that it exposes the shortcomings of the Danish SSN system. 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.

Yeah, he seems confused to me. Well meaning, but not so consistent. What is good is that he is a wrench, that throws itself in the works repeatedly. This is a healthy thing to have.

That is right, but one thing is not like the other. You have always been free to set expiry low on your own certificates, but that is not the same as enforcing it on everyones ceritificate.

/etc/hosts scales like a lead balloon. 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

You can get that, even if you have a phone with the app on it. MitID is perfectly okay with that. At login time you will be prompted for your token code, but there is an option to switch to the app ("Skift til MitID app" in the bo

That sounds like an unnecessary EU standardization. Having the same timezone in Poland and Spain possibly made sense 30 years ago, but now that all communication goes through computers of one kind or another, time conversion is seamless. Fo

Solvespace can also be used for 3D. 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

I really loved Miranda back when I learned about it. I still have the book. I think it never took off because it was quite expensive for universities to use. Im sure David Turner regrets his price model today. Now he has made Miranda availa

I think you are right that the shady actors pretty much can use existing bugs. 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 creat

I assume by third party you mean the authority, and yes, the authority would need to know your personal information. At least enough of it to verify your age. So the ideal is that the authority is the entity that already knows your personal

That is what the example uses. In the real world that would be a digital signature. Look under the heading "Fitting the parts together" to see what the real world solution could be like.

I think that whatever organization that issues your passport, would be a natural choice for setting this up. But it could be some other authority. In a way it is the identity owners and the providers that decide who they will trust as autho

Hash-chains allows the solution to be token-less. You no longer need those per transaction information leaking API calls. You also avoid dependency on a single provider. The communication in connection with a transaction would only go betwe

No, the solution does not require that. It requires that Bob proves posession of a private key, that only he has ever had. That private key could be generated specifically for the commitment that he got from Alice.

Yes. I think that wahtever organization that issues your passport, would be a natural choice for setting this up. But nothing prevents it from being a private company, although I cannot see a sound business model for it. Also it would need

I think the way to go would be for Alice to give you lots of commitments. They are computationally light-weight to generate anyway. That would at least be a good and also simple solution. Maybe there is a perfect solution, but then I dont k

I have mentioned this before, but age verification can be solved by hash chains. They can prove age without compromising privacy. It is crazy that the solutions Discord goes for are IDs and selfies. It definitely gives the impression that t

Another fun fact: German registration plates use a font for which it is difficult to change one digit to another, for example by adding a bit of tape. The font is called FE-Schrift. https://en.wikipedia.org/wiki/FE-Schr
