Super happy to see our great developer and friend @rustam.no with us one more year! 🙂🤗

Occasionally, I discover a developer complaining about the verbosity of #Java Streams. 😮‍💨 We spent 21 years tackling the verbosity and other challenges with Java collections, and incidentally solving many of the verbosity issues with Java Stream. 🏋️ You're welcome! 👇 github.com/eclipse-coll...

Q: Is the Eclipse IDE required to use Eclipse Collections? A: No. Eclipse Collections is a stand-alone Java library and one of many open source projects at the Eclipse Foundation. I was asked again yesterday, and responded w/ the branding section of this blog.👇🙏 donraab.medium.com/there-is-no-...

I answered the question "How do you learn a rich API?" a couple of weeks ago in a Pittsburgh JUG meetup. I wrote the book "Eclipse Collections Categorically" to show how any developer can solve this problem. The path to learning is right in front of you. 👣 www.youtube.com/watch?v=RpOt...

Look what showed up at my door! #EclipseCollections Categorically by @thedonraab.bsky.social! Also, hardcover! Can't wait to see how the final book has become! 😍 #Java

That's what happens when conferences overlap. We had to divide and conquer a little. #JakartaEE #Java

Look who I ran into at CPH! @rustam.no on his way to @geecon.bsky.social and me to @jcon.one Im sure someone is working somewhere, so #eatingWhileaothersAreWorking #Community #Conferences

We had an amazing time at last year's dev2next and cannot wait for our second year at the end of September! Some snapshots from last year 📸 Purchase tickets at- www.dev2next.com/register And don't forget our super early bird tickets are available till May 31st- don't miss out!

That's my experience too. It's good for certain things, writing new code is not one of them. At least for now.

... but @venkats.bsky.social says AI is useful for - generating ideas (an ideation partner) - finding fault with code you present it (a code-review buddy) #DevoxxUK

I remember when GS Collections was downloaded ~20K times a month from Maven Central 10 years ago. At the end of 2025, we will celebrate 10 years of #EclipseCollections at the @eclipsefdn.bsky.social. Here are the #EclipseCollections downloads last month from Maven Central. It's been a long journey.🙏
