There are so many good Prags titles, but I've got a few that come to mind that I want to call out. @joemasilotti.com - "Hotwire Native for Rails Developers" pragprog.com/titles/jmnat... I tech reviewed this book and I was really impressed with Joe's work on it, even not being a Ruby guy.

pragprog.comHotwire Native for Rails DevelopersLeverage your existing Rails codebase to build iOS and Android apps with Hotwire Native – no Swift or Kotlin experience necessary.

@sam-cooper.bsky.social - "Kotlin Brain Teasers" pragprog.com/titles/kotli... Another tech review, and this one was right in my wheelhouse. I've done a lot of work with Kotlin and I was still learning new things throughout the book. The "Brain Teasers" series are always fun and this is my favorite.

pragprog.comKotlin Brain TeasersLevel up your Kotlin the fun way! Solve mysteries, dodge traps, and banish bugs. Sharpen your critical thinking to ace interviews and ship rock-solid code.

Erica Sadun's "Numerical Brain Teasers" pragprog.com/titles/esbra... This is not like the other brain teasers books but instead is a collection of fun number puzzles. I reviewed this a few years back and loved it, so I broke it out again lately. Still love it.

pragprog.comNumerical Brain TeasersTest your math, and sharpen your skills. These fun and twisty challenges will puzzle your brain, tease your number sense, and get you thinking outside the box.
