What's the lockin? Is it really harder than just swapping the jdk path to switch between Coretto and OpenJDK? I understand Coretto being preferable for performance and security patches but I don't imagine it's that big of a deal if one eventually had to switch

Didn't ask

You don't need to use the same one. Just don't expose it publicly in libraries.

It's a lot better with some notable exceptions. First, .NET Core is multiplatform by design, so it is by default quite portable. The .NET Core CLI is extremely powerful and means a CLI workflow is totally feasible (and also simplifies CI pipelines). The new "multiplatform" application framework, MAUI, runs on Windows, Mac, iOS, and Android, but not Linux/GTK/QT etc. You can maybe attribute this to the design philosophy of abstracting native controls, of which "Linux" itself has none, but either way it's useless on Linux. Third party frameworks like Avalonia do work very well on Linux.

Despite .NET being relatively friendly with Open Source, Java will probably remain the first choice for FOSS devs for a while, if only due to history and traction. You could write a C# Lemmy alternative, but it wouldn't necessarily be faster or simpler or better in any particular way than a Java version. I'd certainly rather contribute in Java than start from scratch in C#.

C# isn't really the go-to for high scale distributed systems. But it's extremely easy for a small team of developers to set up a really solid service really quickly. I don't have experience with Go so I can't really compare, but I find ASP.NET Core very pleasant to work with, and I also appreciate the suitability of C# and .NET libraries for both backend and frontend work.

Nullable reference types are (a completely mandatory) bandaid fix in my opinion as a .net dev. You will encounter lots of edge cases where the compiler is unable to determine the nullability of an object, e.g. when using dependency injection to populate a field, or when using other unusual control flows like MediatR. You can suppress the warnings manually at the slight risk of lying to the analyzer. Objects supplied by external library code may or may not be annotated, and they may or may not be annotated correctly. The lack of compile-time null checking is occasionally an issue. But that said, NRT makes nullability a significantly smaller issue in C# than it used to be

You can also easily write your own option monad or use a tiny library that does.

No but you have 8 boobs like a cat, enjoy

Yup, you'll notice the only thing distinguishing C from R^(2) is that multiplication. That one definition has extremely broad implications.

For fun, another definition is in terms of 2x2 matrices with real entries. The identity matrix

1 0
0 1

is identified with the real number 1, and the matrix

0 1
-1 0

is identified with i. Given this setup, the normal definitions of matrix addition and multiplication define the complex numbers.

One definition of the complex numbers is the set of tuples (x, y) in R^(2) with the operations of addition: (a,b) + (c,d) = (a+c, b+d) and multiplication: (a,b) * (c,d) = (ac - bd, ad + bc). Then defining i := (0,1) and identifying (x, 0) with the real number x, we can write (a,b) = a + bi.

Reminds me of 2048 making a slightly worse clone of Threes and then releasing it for free.
