I’ll be honest, #ScreenshotSaturday is about the only thing that keeps Bluesky fucking tolerable for me, as a respite from the steady stream of doom reposts. Especially you #pico8 developers—it is amazing and inspiring to see how creative people are within its constraints. 👏 👏 👏

Recommended books for learning Ruby
Ruby is a beautiful programming language that balances functional programming with imperative programming with ideas inspired from other languages (Perl, Smalltalk, Eiffel, Ada, and Lisp). If you want to take a deep dive into its fundamentals and learn more about what makes Ruby a favourite tool for programmers, below is a list of recommended books to start your journey. ### Learn to program A thorough, but lighthearted approach that teaches you the fundamentals of computer programming, with a minimum of fuss or bother. Whether you are interested in a new hobby or a new career, this book is your doorway into the world of programming. ### Programming Ruby 3.3 (5th Edition) The Pickaxe Book, named for the tool on the cover, is the definitive reference on Ruby, a highly-regarded, fully object-oriented programming language. This updated edition is a comprehensive reference on the language itself, with a tutorial on the most important features of Ruby. ### Learn Enough Ruby to be Dangerous Designed to get you started writing practical and modern Ruby programs as fast as possible, with a focus on the real tools used every day by software developers. ### Practical Object-Oriented Design (An Agile Primer Using Ruby) This book is a programmers tale about how to write object-oriented code. It explains object-oriented design (OOD) using realistic, understandable examples. POODR is a practical, readable introduction to how OOD can lower your costs and improve your applications. ### The Well-Grounded Rubyist, Fourth Edition For over fifteen years, _The Well-Grounded Rubyist_ has taught beginner and developing Ruby programmers the veteran secrets of Ruby. This new fourth edition of the groundbreaking classic goes beyond syntax and commands into how a Rubyist really thinks. ### Eloquent Ruby, Second Edition Write better, clearer, more focused Ruby code by becoming truly fluent in the language. To express yourself eloquently in any language, you need to go beyond its vocabulary and syntax.

"I just don't understand it. I'm not even that old, | was born in the 90's. How can you be called they or them? You're a single individual not a group of people"

"What pronouns would you use to refer to a theoretical person of unknown gender?" 

"I will not refer to them using any pronouns until their gender is clear. That would be the respectful thing to do as well."

I just learned about Roundhouse. Good timing as I wonder what to do with a couple of Rails apps I'm worried about supporting as Rails long-term. www.rubyforum.org/t/have-you-guys-s… #Rails
rubyforum.org
Have you guys seen Roundhouse?
This is a wild project which takes your rails application and translates it into C#, Crystal, Elixir, Go, Kotlin, Python, Rust, Swift, and TypeScript. It also translates it into magic-less ruby which is incredibly verbose but runs faster and is more JIT friendly. He claims it also runs under spinel which means you could compile it to a binary. Crazy project.
