Two years ago, I wrote my most popular blog by both views and reads: "How to get an item from a Set in Java." According to my Medium stats, this blog has received 44K views and 16.4K reads. Most of the referral views were driven by Google, at about 40K. 🤷‍♂️ medium.com/javarevisite...

Every #Java class viewed in an IDE and JavaDoc should be a mind map to its methods by category. Smalltalk had message categories built into its Class browser 45 years ago. 🤔 I wrote this blog a year ago. IDEs can help show the way, but shouldn't have to.👇 donraab.medium.com/grouping-jav...

My book, Eclipse Collections Categorically, will be available on on Kindle Unlimited (KU) until October 12, 2025. The following blog is a how-to-guide on getting the most out of the book given limited time. If you have KU, find out what's in it for you.💡 donraab.medium.com/the-authors-...

Just upgraded the project for my @dev2next.bsky.social talk w/ @zakhav.bsky.social to #Java 25. The project uses #EclipseCollections 13.0, and works just fine. EC 13.0 works w/ Java 17+. Not there yet? EC 12.0 supports Java 11+. Stuck in a "tech coma"? EC 11.1 supports Java 8+. 👍

To find out why a former Smalltalk developer open sourced and worked for 21 years on a collections framework for #Java, just read the Preface. Read the entire book to see what 21 years of OSS community effort can produce. Content up thru Chapter 1 is FREE online. 👇 read.amazon.com/sample/B0FFM...

Every now and then, the idea of contributing to Open Source Software crosses the mind of every developer. In this blog, I want to tell the story of my first Pull Request. #oss

Is anyone out there still using groovy-lang.org? Feels like it rather dropped off a cliff (apart from defining gradle builds). Is there a community out there that I'm just not aware of? #java

Earlier this summer, I went to Princeton NJ to hang out with the the editor of my book, Richard. We celebrated the launch of the Kindle version of the book, with a coffee and cake at Small World Coffee. It's a small world after all. One month to go on Kindle Unlimited availability if u subscribe. ⏳

Sometimes the clouds steal the show. I love these times. ⛅️

This was the first time I used AsciiDoc for tables in a Medium blog. This was five months before I discovered how to group methods in #Java by method category using Custom Code Folding Regions in IntelliJ. Java development will never be the same for me now. 🤷‍♂️ medium.com/javarevisite...

Don't believe the hype. Summer ain't over. Screw school. Get to the beach, sun fun, crave waves, and stand in sand!

After 21 years of developing, using, teaching, collaborating, blogging, podcasting, writing a book about #EclipseCollections, one thing motivates me to keep going. There are millions of #Java developers that don't know what they have been missing for 21 years. 🤔 If you know, then let them know. 🙏

Choose your caffeinated weapon. Don't bring a cup to a thermos fight.

Sometimes all I need is a bike ride and a sunset.

Today is my cousin Chris' birthday. He would have been 55 today. He died at age 42 after a long battle with brain cancer. I rode my bike 8 miles in his memory today to pass 125 miles total for August. I miss you bro. ❤️

I wrote my 250th blog on Medium today. Thank you for reading my blogs for the past eight years. 🙏 donraab.medium.com/i-m-not-catt...

Honestly, thanks for writing it. It's so rare now that I find a book (or any other source, for that matter) that actually shifts my perspective about not only how I code, but think about problems in general. My bookshelf is bursting at the seams, but few books have a place as a constant reference...

Thank you, Joe! 🙏 It only took me 21 years to write this book. It's nice to hear positive feedback about something I've worked on for so long. I hope folks globally take advantage of the free book promotion while it lasts. 🥂

A guide to Eclipse Collections now comes with its own guide! 🥳 (And no, there is no guide to the guide to the guide, 🪆-style.) Really, this blog can be a useful pre-read to help you make the most of “Eclipse Collections Categorically”, depending on your goals, learning style, and time constraints.

I met a developer this week who had never heard of Smalltalk. We are failing ourselves by not learning the innovative things that came before. Smalltalk might be the rejuvenation your programming soul has been longing for. It is different enough to warrant study. 🤔 blog.devgenius.io/a-little-sma...

Published a release blog for the back to back releases of Eclipse Collections 12.0 (Java 11) and 13.0 (Java 17). Thanks to all of our users, contributors, and advocates! 🙏Congrats and welcome to our two newest #EclipseCollections committers! 🎉👏 donraab.medium.com/eclipse-coll...

I'll stop coding in #Java when developers discover Smalltalk was a better technology. Java keeps working, improving and still feels like a great investment twenty-five years later for me. Our collective memory of what came before is fading. What has come after has not been substantially better. 🤷‍♂️

I spent a couple hours last night playing Galaga, Centipede, Millipede, Donkey Kong, Dig Dug, Time Pilot, Tron, Asteroids, Ms. Pac Man, Super Pac Man, Joust, 1943, Space Invaders, Tempest, and a bunch of pinball machines at a standup arcade. Timeless.

Shout out to @joesteel.bsky.social for sharing this blog in a thread with @headius.bsky.social about overflow fun in #Java he misses in Ruby. 😅 I forget some things I explore in blogs, which makes me happy that I take the time to write them down. Enjoy! 🙏 donraab.medium.com/10-billion-i...

I received an unexpected compliment from a friend today. I hadn't done anything special to prompt it. It was most welcome. 🙏 I hope everyone receives appreciation for doing what they do as a matter of course. It's a beautiful day. My cousin Chris says so.🤗 donraab.medium.com/life-in-a-be...
