I'm writing another book, and the first few chapters are available through Manning Early Access now! For 50% off! hubs.la/Q03Q9PGP0 More details, and the story of how I came to write it, are on my blog at ericlippert.com/2025/10/30/i... It feels great to be writing again after a long break. :)

Damn, it is hard to believe, but Java compiles the `switch` over the `String` values by using the runtime-provided `hashCode()` impl. Meaning it is not possible to change the `String.hashCode` impl w/o recompiling all the Java programs.

This was a great read. No idea how to get on top of this, perhaps pulling random people away from keyboards? Who knows! techtrenches.substack.com/p/the-great-...

Compiler-generated classes for C# 12 `[collection, expressions]` still look awful in the debugger, pls vote: github.com/dotnet/rosly...

Before C# 14, there were just a few rare erasure conflicts in C#, like when u define overloads differing only by `ref` /`out`. With C# 14 extensions, we are one step closer to Java, with its stupid "have the same erasure" conflicts

Is `internal interface I` implementation in `public class C : I` is a part of the public API surface? Can u erase the `: I` without breaking the consumers? Given `public interface IPublic<T>`, what about `public class C : IPublic<I>`?

Periodic reminder to check your CPU thermal paste. Never use ancient thermal paste. Make sure the layer is thin and spreaded evenly. And don't be lazy like me, result: throttling is absent, -20°C, -900RPM on AIO fans...
