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! 🙏

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!

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. 🙏

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. 🤔

Eclipse Collections, is there anything they can't do? [hint: the answer is in the book]

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.
