Rewriting in a different language rarely, if ever, solves the underlying challenges 🤔
Outlandish stuff. It's almost like - hear me out - that there are *other* classes of bugs aside from memory errors?

This post shows the gulf in understanding between much of the AI community and enterprise Yes, there is bureaucracy. But - The risk profile needs to be different - Security is a real thing. Along with privacy & regulation Startups can risk building houses of straw. Banks can't
Meanwhile, In Enterprise Land - AI adoption is super slow - organizations are routinely blocked by "security" - "AI committees" stuck in analysis/paralysis - humans continue to do all the heavy lifting This is in STARK CONTRAST to the early adopter community 🤯🤯

Getting accepted to speak at conferences never gets old. Especially the ones I really enjoy being at. With that said I don't take it for granted. Very grateful to be a part of this community and to continue to do what I love doing 💚

So much this. `record` all the things!
Looking at some legacy Java right now... and yeah, I never want to see non-local mutation again. Local mutation (i.e. vars and loops scoped to a function) is OK, but tracking down dataflow through setters and mutable fields is completely intractable for me.

Edutainment is possible. Even for backend technology, like #Java. Proven by @MaritvanDijk77 and yours sincerely ;-)

Removed Clean Code from my students’ reading list this year. Replaced it with The Pragmatic Programmer. No regrets.

At ask the architects at #Devoxx - have you considered rewriting C++ parts of the JDK - short answer: no
"You should really rewrite this legacy Java code in Kotlin/Rust/Scala/Brainfuck/..."
