I run a stack with garbage collection for most of my tasks: I just keep things I need to do in my head, and if I think of it a lot it has references to it. If I stop thinking about it it will eventually be purged by GC :D

I wonder what is the longterm plan of those that want to ban the party. We have a situation where (depending on the state) more than 40% of the voters vote AfD. If you ban the party, where would one expect the current voters to go to? I don't think they would vote center-left then...

Yes. With Fortran 90 most of the real archaic stuff was already gone. And they keep publishing new standards.

I wrote Fortran for my first job as a software developer in 2018 for simulation solvers. Still like the language! Modern fortran is very very fast and much nicer to use than C for linear algebra. So in my opinion for numerical calculations it remains the best language, even today. Happy Birthday!

Yes, buuut: I think we are already really close to that for a long time. You could learn a lot just from internet and youtube. But most people, I feel, just do not like to neither do plumbing/diy nor learn about it. Like if I tell people they can save hundreds of € by changing their own brake pads and that it is really easy to diy, they just shrug and go to the mechanic. So I am not sure if AI will really increase the percentage of people willing to learn these skills and do repairs etc

That was not my point. Sorry if I did not make it clear enough: The point is, the mesh is a completely separate entity. It is an attempt to make a copy of the CAD geometry. Whereas with IGA you can actually calculate on the CAD geometry itself (at least for easy geometry without trimmed surfaces).

Normal finite elemts does not care. The mesh ist just put on your 3d body that can be an stl or a step or whatever. The FEM only knows the nodes and nothing else. The mesh geometry is completely separate from the CAD file.

Now there is a method called Isogeometric Analysis (IGA) that was meant to improve this. It uses NURBS functions (just like CAD) for the shape functions of traditional FEM. The idea was that now, if you have NURBS describing the CAD geometry you can skip meshing and just directly calculate on the real geometry. But it did not catch on. The reason being basically, as far as I remember, was that most CAD geometries of interest are not pure NURBS. But they are operations of NURBS (think cube minus some other cube - trimmed surfaces). And IGA has problems with that.

This is a problem that openSCAD will probably also not be able to overcome. Maybe at times it might be easier to create NURBS geometries without trimmed surfaces. But most probably that cannot be done in most cases of real world significance.

This is still unbelievable to me, up to this day. If the opposition choses to run for office with a moron, couldn't you at least find a candidate that is not demented.. You can't make this up..

Yes that is a real problem at work. A lot of stuff is done in containers or virtual devices and jetbrains remote developping workflow takes too much time due to this transfer. VsCode is much faster there.

yes. They used it for a heart surgery on a new born that I know.

Once upon a time adidas made shoes that were wide enough for me. Then somehow they decided to make them narrower and I had to search for wider shoes. The search was very difficult, as it seems that most shoe producers do not produce actually foot-shaped shoes. I bought my first pairs of Altra half a year ago, and I am very happy! The fit is really great. I will not switch to anything else, as long as they continue producing in this shape.

> Perhaps the tendency to complain is a necessity to achieve a high level of efficiency.

I am pretty convinced about that. Especially after having lived and worked in other countries where people like to complain less. If people will just accept and not complain, problems also will not get fixed.

I was once in a museum in Bolzano, Italy. And they had the ice man mummy there (we call him Ötzi). He died like 5000years ago. And his "axe" was made of copper from some mine very far away. So even this guy probably did not know how everything he had was made. There is a theory that he was probably very rich. So maybe less rich people were more in touch with what they owned. But still I found it fascinating that even so far back people relied on technology and materials that they didn't really know about.

The A/C cannot keep up the load, due to the exteme heat. So they decided to just not cool one part of the building, to be able to keep cooling the other part .. It is now interesting who was in which part ;)

I don't think it is changing the goalpost. The law prevents more than half of Germany's inhabitants from installing ACs, because they are renters. Also landlords cannot just install AC just fine. If you just own an appartement, you need the consenst of all other owners in the building. This is also a law. Therefore, practically no landlord will agree to the request to install outside AC, unfortunately.
