I'm seeing lots of AI generated Java Dukes appearing with a mouth, feet, ears and more. Tip: when using AI, upload this “Duke Specification” image, prompt AI to follow as a reference. I think you'll find the resulting image is much better. Ex: "draw duke on a skateboard referencing this spec image"

"I need an array of a generic type. Why won't the compiler let me create one?"
"How do I find the intersection of two Sets?"
These and all other questions about generics and collections are answered in the newly published 2nd edition of Java Generics and Collections. 1/2

"Why haven't they fixed this yet?" @smarks.bsky.social and Maurice talking about ConcurrentException etc in #java at #devoxx
Great talk, but when they cover Vector and Hashtable, I can't stop and think:
"Why haven't they deprecated this yet?"

The Minnesota assassin appears to be a hate-filled right winger. So can we stop walking on eggshells about MAGA's legitimization of political violence?
Yes, Republicans have also been the target of inexcusable violence, but this isn't a "both sides" issue.
