There are lots of good current O'Reilly books. I think they have gotten a bit less conversational and reading books like Mastering Regular Expressions was almost like conversing with a smart friend or teacher than a dry technical book. Programming Rust, for example, is a great book but I don't think it has "the funk" in the same way as a lot of 90s O'Reilly books. Although I'm probably reading the wrong ones. Plus I'm distracting myself from what I intended to do, which is unnecessarily dumb.
