I recently finished reading "Writing For Developers" by @cynthiadunlop.bsky.social and @sarna.dev.
Honestly, it was a fantastic read. Even if I started getting more and more experience in writing, I learned so much from that book!
Highly recommended!

Thanks to Writing for Developers, I finally finished a blog post draft that I procrastinated on for a month. I kept finding excuses not to write it, but in the end, it wasn’t as hard as I thought. Now I know these excuses aren't valid after all.

Happy Friday 💙

Writing for developers is pretty much how I made my living — with breaks of various durations — from 1980 through 2023. I learned how to do it on the job, by trial & error — lots of error. If only this book had existed back when I was muddling in the dark! Don't do it my way. Get the book!
The book that @sarna.dev and I co-authored on writing engineering blog posts is now published. And it’s flanked by the best imaginable “bookends”: a foreword by @bcantrill.bsky.social and an afterword by @scott.hanselman.com! Details and Amazon/Manning links at bit.ly/3AVPWn9.

Finally -- Amazon has the books.

Paperbacks are shipping now in the US, February in India, and... eventually... in Europe. Kindle editions are available for download globally.

Found this policy (via @cynthiadunlop.bsky.social) from Sun Microsystems on engineers writing technical blogs about their work at Sun from 2004. I feel like it’s as relevant today as it was then.

I snagged a digital copy of Writing for Developers for @eatonphil.bsky.social’s book club.

I’m giving “tech book on a kindle” a try for this one.
