Non-evil people, please take note.
We had a lot of fun in How to Sell today.

When we do this, we get the question "What if you're trying to sell someone on an idea?"

Honestly, the biggest mistake non-evil people make is focusing on changing minds instead of changing behavior.

And not understanding the perceived costs.

"Let me make it clear: without people at the top of their game sharing their experience and knowledge — regardless of whatever “game changing” technology is in place — we are pulling up the ladders and committing our industry to stagnation and death."

You’ll miss publishers when they’re gone
Ever since Piccalilli started to get traction, I’ve always seen CSS-Tricks, Smashing Magazine and A List Apart (among others) as peers. We all help each other behind the scenes and importantly, back each other. When CSS-Tricks was initially acquired by DigitalOcean, I was really happy for Chris. The work that he’d put into that publication […]

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.

Hi, just because a software tells you it’s “reasoning” or “thinking” doesn’t mean it actually is.

You won’t believe this but programmers can make software lie about what it does.

Maybe programmers need more guardrails.

1Password faced immediate backlash from customers this week over a $300,000 pledge in support of a Linux distro created by David Heinemeier Hansson, who has regularly published overtly racist blog posts that include comments calling for deportation of ethnic minorities in Europe.

Has anyone been a very active @1password.bsky.social user, including their more advanced features (SSH key management, OTP, passkeys, team accounts, etc), and successfully migrated to an alternative? I've been using it for over a decade, but I'm upset about the direction the company has been taking.

Miren Runtime v0.14.0 is out 🚀

This is a version of the world I would love to see.

Not sure if we'll be able to pull it off (as an industry), but I think it still worth trying to move in that direction.
The specification is not a document.

This is a long one. I’m trying to work through what the durable artifact of software becomes when code is cheap to regenerate, and what that means for documentation, production evidence, decisions, evaluations, and provenance.
