Java 25-year anniversary coin

Thanks to the new 3D-printer, I can finally give this coin a nice spot on my desk.

Congratulations, Shar!

Notification saying "CFP IS CLOSED - We warmly welcome your proposals, which can be submitted until December 19th, 11:59 PM."

Now that's one nice example of an ambiguous message. Or is are you running Schrödinger's CFP, @amsterdam.voxxeddays.com?

Bonne chance.... It's probably not an easy task at your scale!

"Every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed."

Why can't we have both? 😉 The things you and Jim do for the global Java community are exceptional.

Looking forward to seeing you in the new year!

J-Fall 2025: A Day to Remember - NLJUG - Nederlandse Java User Group On November 6, 2025, the Java community came together in Ede for another great edition of J-Fall. Th

It's been more than a month since #JFall, but it's nice to go over the memories. Especially when you see your name in the Top 10 of best-rated speakers 😊

Do I need that to feel like a good speaker? No! But it is flattering anyway, so thanks to everyone who rated my talk!

🚀 mcs 0.9.3 has just been released! Check https://github.com/mthmulders/mcs/releases/tag/v0.9.3 for the details.

Ha, printed a similar thing last week: bucket to the side. Curious if we found the same one?

Yeah, blame it on the age 👍🏻

Nevertheless, congrats!

If you need me, find me in January.

Two filament spool adapter rings to ensure proper rotation of carton spools in a Anycubic Kobra S1 Combo.

Fresh off the bed. More of a utility print, really. Or is this the "printing parts" category? Nevertheless, the first two prints came out really nice. And it was a good test case of "how does this actually work?"

A few loose ends of PLA filament that jammed the feeder.

First lesson of 3D-printing. When the manual says to ensure the filament should have a straight end before inserting it in the machine, do so.

On the bright side, I've learned how to unjam the machine.
