I respect and understand the appeal of LISP. It is a great example of code not having to change all the time. I personally haven't had a compelling reason to use it (post college), but I'm glad I learned it and I wouldn't be

"Just don't write bad code" means that you can easily avoid some of the anti-patterns that people list as weaknesses of C#. Yes, maybe you inherit code where people do those things, but how much of that is because of C#, and

Huh? 10 years ago was 2015. Entity Framework had been around for nearly 7 years by then, and as far back as I remember using it, it used source generators to subclass your domain models. Even with "Code First", it generated subcla

That is tedious with or without a source generator, mainly because there's a much better way to do it: public Optional<string> Name; With Optional being something like: class Optional<T> { public T? V

Let's be careful about exactly what we mean by this. When we say an algorithm is O(f(N)), we need to be very clear about what N we're talking about. The whole point is to focus on a few variables of interest (often "number of

Attributes do nothing at all on their own. It's someone else's code that does magic by reflecting on your types and looking for those attributes. That may seem like a trivial distinction, but there's a big difference between

A "measurement" in the general sense (not quantum) is about amplifying or isolating some signal out of all the noise. I simply don't agree that all measurements boil down to relative displacements. Did a chemical reaction occ
