What Kindle book can you get for $0 on January 1st, 2026?

A very interesting read from @thedonraab.bsky.social, as always!

I asked and answered only one question in StackOverflow in 2025. I got some great advice from @shipilev.bsky.social which helped me do the necessary research to answer my own question. I even got comfortable building from source to see some new JOL improvements. 🙏 stackoverflow.com/questions/79...

Merry Christmas! 🎄 Also, happy 10th Anniversary #EclipseCollections! I always wanted an Eclipse Collections hat. My wife had two made for me with the EC logo. A triple surprise, since she didn't know that today was the 10th anniversary of EC. 🙏 Last chance until New Years for $0 ECC Kindle book. 👇

I just saw this type while browsing a code base in GitHub. Map<Set<Integer>, Set<Integer>> If you have types like this in your code base, I only have one thing to say.

Tomorrow is day one of three to book your tour of #Java collection fundamentals in 2026 for free on Amazon Kindle. Happy Christmas Eve! 🎄

GS Collections was open sourced by Goldman Sachs 14 years ago. The 10th anniversary of #EclipseCollections first release @eclipse.org is in 4 days. If you're waiting for new Collections in #Java after 30 years, the wait continues, while EC continues to grow & evolve. 💗🦋 medium.com/javarevisite...

If you're unsure if you'll need to know programming fundamentals after 2025 including API and library design, TDD, OOD, data structures, lambdas, efficiency, performance, then maybe get a free Kindle copy of ECC on one of these three days just in case. 🤷‍♂️ A review blog.waynebeaton.ca/posts/ecc/re...

The end of 2025 is drawing near. It's time to plan the next 5 years of #EclipseCollections. This month marks the 10th anniversary of #EclipseCollections as a project at the Eclipse Foundation. 👀🎉🥳 Let's look back 5 years to see the plan and mark the progress. 👇🙏 donraab.medium.com/the-next-5-y...

Joining JSR 335 EG was a tangent. Working on Eclipse Collections is a tangent. Presenting at conferences is a tangent. Writing blogs is a tangent. Learning AI is a tangent. A tangent is not a distraction. It is an opportunity to learn and leverage.

Being a Java Champion and Advocate does not mean I get to snap my fingers and make changes to #Java. It helps when I can effectively communicate and socialize a "What if..." Few of my "What ifs" will see daylight. I'll keep asking and learning from them anyway. 🤷‍♂️ donraab.medium.com/what-if-a-de...

In the age of GenAI, I hand wrote a blog about a 27 year old protected field in #Java named modCount. The sunset doesn't mind how it rises.

I fell down the Raabit hole again. Do you know what modCount is? Blog in progress. Here's a mind map in case you're wondering about the 131 places the AbstractList modCount protected variable is referenced in the JDK. It is the godfather of the modCount mafia.

My latest blog: Mind Maps Didn't Make Me Scroll It only took me a few years to realize that mind maps could help me communicate the package design in the api and impl jars for the #EclipseCollections open source #Java library. Lesson learned and shared. 🙏 donraab.medium.com/mind-maps-di...
