System.Buffers v4.0.3.0 / v4.6.28619.01 @BuiltBy: dlab14-DDVSOWINAGE069 @Branch: release/2.1 @SrcCode: https://github.com/dotnet/corefx/tree/7601f4f6225089ffb291dc7d58293c7bbf5c5d4f / v4.6.28619.01

You’re right. Thanks for correcting me. The logic of applying the predicate for the two are inversions of each other, and they are even implemented in the same file: AnyAll.cs.

- EF Core is not MSSQL first. EF Core is an abstraction layer and is in no way tied to Sql Server. In fact, Microsoft's own getting started tutorial uses Sqlite (1). I've personally used the Postgres drivers in production and they are as good/production-ready as Microsoft's SQL library for EF Core.

- "Many libraries ship with two implementations..." I've yet to come across these "many" libraries in the 5 years since I've been building services with .NET Core.

"The community is really culty" - I'm not sure where this is coming from. It's hard to refute such vague criticisms.

- "It's practically open source in name only" - Here is the base class library source: https://github.com/dotnet/corefx/releases

Dotnet foundation publishes their C# coding style along with an editorconfig and some tooling to support it.

I created the bug report on GitHub. After that, the .NET development team fixed some code fragments described in the article. Among them - the errors with interpolated strings. The corresponding pull request.

I like the first code example on https://crystal-lang.org

Obviously as an interpreted language, it's never going to be as fast as something like C, Rust, or Go. Traditionally the ruby maintainers have not designed or optimized for pure speed, but that is changing, and the language is definitely faster these days compared to a decade ago.

If you like the ruby syntax/language but want the speed of a compiled language, it's also worth checking out Crystal[^1]. It's mostly ruby-like in syntax, style, and developer ergonomics.[^2] Although it's an entirely different language. Also a tiny community.

Crystal is a nice language that's not only simple to read and write but performs very well too. And the documentation is amazing as well.

Ruby is a super fun scripting language. I much prefer it to python when I need something with a little more "ooomph" than bash. It's just...nice...to write in. Ruby performance has come a long way in the last decade as well. There's libraries for pretty much everything.

My modern programming toolkit is basically golang + ruby + bash and I am never left wanting.

I do find Crystal (https://crystal-lang.org/) really interesting and am hoping it has its own "ruby on rails" moment that helps the language reach a tipping point in popularity. All the beauty of ruby with all of the speed of Go (and then some, it often compares favorably to languages like rust in benchmarks).
