Programming is fun! If you are programming and not having fun, then you may be doing it wrong. - Donald Raab #quotes #quoteoftheday

If anyone would like to help a hungry developer out (and support the development of pitest) I've just setup a GitHub sponsorship link. github.com/sponsors/hco... #java #oss

Today, March 16, 2026, is the 1️⃣ year 🎂 of the "Eclipse Collections Categorically: Level up your programming game" paperback release. 🎉 Just a few more hours left to find the "$0.00 to buy" offer of the Amazon Kindle book version in your Amazon marketplace website. 👀 www.amazon.com/Eclipse-Coll...

Indeed

Just *1,5 hours* to go! Tick-tock! Also, my friend and fellow #JavaChampion @patbaumgartner.com will be hosting this session. I am very excited about this! 🙌 Who's joining?

The #EclipseCollections #Java library has been FREE and OSS since Dec. 25, 2015. To celebrate the 10 year anniversary, you can get a free Kindle version of the "Eclipse Collections Categorically" book on Dec. 24 & 25, 2025 and Jan. 1, 2026. Happy Holidays! 🤗 🥂

Professional societies keep beclowning themselves buying into a lie about what an LLM "summary" is. They are inherently counterfeit: not an epistemic product of the ideas in the source, but summary-shaped text linguistically based on *other* works (in the training corpus) that use related language.

I updated my blog comparing the memory cost of ArrayList and FastList, essentially showing the difference of the presence or absence of the modCount field. Two JVM properties are now enabled and disabled and results compared using Java Object Layout. Enjoy! 🗜️ donraab.medium.com/one-positive...

A word for my Potential Future Sponsors! github.com/sponsors/cow... ... if you want to help speed up Jackson development.

JUnit is undoubtedly one of the most important projects in the #Java ecosystem. And it's 100% free and open! Let me be frank: If we can't get THIS project to the point where a single maintainer can focus on it, then what does that say about our commitment to Free & Open Source Software? 1/3 ⏩

Need primitive type support and missing container types in the #Java Collections Framework? Many folks are quite content to keep waiting for Valkyries to come and take them to [project] #Valhalla, but some chose to follow Alan Kay’s maxim: "The best way to predict the future is to invent it"

Still waiting for the #Java of the future to solve all your collection problems? #EclipseCollections has been solving them since J2SE 1.4. Stop waiting. Start refactoring. Eclipse Collections makes Java look, feel, and run like a brand new programming language. donraab.medium.com/refactoring-...

I've been using RandomAccessSpliterator for years in #Java without realizing it. I wrote about this default spliterator years ago. I wrote about it again after learning it is used by immutable Lists created by List.of() and Stream.toList(). Deja vu all over again. donraab.medium.com/spliterating...

I love having 75 minutes to give the "Refactoring to Eclipse Collections" talk at @dev2next.bsky.social with @zakhav.bsky.social. ✔️ Engaging Slide Content ✔️ Live Refactoring ✔️ Memory Costs with Java 25 and JEP 519 ✔️ Ask us anything Yeah, we got time. Tuesday - 10:45am - Salon FGH 🙏

Join @zakhav.bsky.social and myself tomorrow at 10:45am in Salon FGH to learn why and how we've written #Java code with #EclipseCollections for the past 21 years. I brought a couple paperback copies of "Eclipse Collections Categorically" to give away at the end of our session. Hope to see u there! 🙏

Using JDK Collections? Lost in a maze of factories? Drowning in streams? Wishing for a better way? Then gather your Gatherers, collect your Collectors and attend "Refactoring to Eclipse Collections" talk at @dev2next.bsky.social to level up your #Java collections game with me and @zakhav.bsky.social

I am excited to speak at @dev2next.bsky.social and to get insights from talks and workshops by industry experts! If you are at dev2next and this drawing gives you the same vibes as the words Enterprise Architecture, join me and we will discuss ways to make architecture more relevant and impactful!

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...

By Grabthar's hammer... what a perfect gift this book makes. The only reason I didn’t get it today is because I got the very first edition right when it came out back in March. Anyway, can’t think of a better way to wrap up Father’s Day than sitting down with a fine beverage and a good book.

#Java peers, I ask you to please follow @thedonraab.bsky.social. His expertise and experiences are worth learning more about.

First we had a text generating machine, but it wasn't enough to raise billions, so it became branded as AI. A year later we still had a text generating machine, but to raise more billions Altman started hawking AGI. Now even AGI isn't enough for yet more billions, so out comes Super Intelligence.

The paperback version of my book, Eclipse Collections Categorically, has been available since March 16th, 2025. The hardback version of the book will be available on April 30th. Both versions include 200+ #Java code examples in full-color. Thank you, and enjoy! 🙏 donraab.medium.com/book-eclipse...

Thursday after #JavaOne, I saw @starbuxman.joshlong.com create a GraalVM Native Image with #EclipseCollections. I never tried before. A reason some folks provided in the past for not using Eclipse Collections was jar file size. If you're using GraalVM Native Image, what reasons do you still have?

Really excited about presenting at #InfoQDevSummit. Come to my talk to learn about Java Data Frames and how they compare to Data Frames in other languages! But I am also super excited about gaining insights from amazing speakers, great networking opportunities, and "hallway track" conversations!

Hardback version of my book, Eclipse Collections Categorically (pictured left), will be available at the end of April 2025! 🙏 WIIFY? Learn to maximize/optimize your usage of high quality OSS #Java code that has been used in production apps and libraries for 21 years. More WIIFY + link in comment.

🚨 Early Bird Reminder! Book before April 15. Get practical insights. Learn what’s next. Bring strategies back to your team: 🔹 #InfoQDevSummit Boston | Jun 9-10 🔹 #InfoQDevSummit Munich | Oct 15-16 🔹 #QConSF | Nov 17-21 🔗 bit.ly/4lHJC5x

Looking forward to the packed agenda, including @frankgreco.bsky.social's talk - if his previous talks are any indication 😃, it will be chock-full of hype-free practical advice to Java developers looking to integrate AI into their applications.

The CFP is closing this Friday for @dev2next Join those who have already submitted their proposals, before time runs out. www.dev2next.com/cfp

So, for what it's worth: I don't think AI is taking over jobs because it's better than people or even good at its job. I think it's taking over jobs because it's cheaper than people and bosses like cheap and aren't necessarily aware of the (very high) risk of bad, dangerous quality output (7/7)
