I have been venting a lot about #JDBC driver in that context, and I want to say something positive: The Clickhouse one is so well documented:

https://clickhouse.com/docs/integrations/language-clients/java/jdbc

especially wrt type mapping (super helpful), and than I haven't even covered the fantastic page on date / date time (some people will relate to that very hard):

Let's introduce a @NullPropagates annotation
A blog by Jacob

It’s finally mature: a framework to define nullability in Java. There have been so many attempts, but JSpecify is here to stay. Now that this has been addressed, another challenge comes to mind: How can we eliminate the boilerplate of handling incoming null arguments?

Java 27 released

Speaking of unsexy programming, we've got a new Java release.

Featuring thousands of performance, stability, security, and productivity improvements, Java 27 (Oracle JDK 27) provides a strong foundation for continued Java innovation. To help organizations prepare for more secure communications in a post-quantum world, Java 27 advances its post-quantum cryptography (PQC) capabilities with hybrid key ex

It took three months but the first version of my #Java property-based testing library is finally published! https://github.com/josephjunker/presume

Reasons why you might like this:

- MIT licensed, no unusual limitations
- 98% human authored
- Supports both direct and functional styles, which makes it easier to define complex and recursive generator types

Reasons you might not like this:
- Around 1-2% LLM authored (I ran out of steam while fighting with Gradle configuration and fixing/testing bit-twiddling logic in 3 methods)
- Still very new and not remotely at feature parity with more mature solutions
- In dire need of more documentation, which I hope to write in the next couple of weeks.
- Uses what I believe to be a novel shrinking algorithm, which appears to work well but which is not as battle-tested as the Hypothesis approach.

Really interested to hear people's feedback on the code and API!

Download #Java27 from your favorite vendor from inside #IntelliJIDEA
JDKs are added as they appear. #Java

This suprises me a lot. Oracle isn't a group I tend to think of as doing the right thing often, but check out the "OpenJDK Interim Policy on Generative AI".

The final policy remains to be seen, but what's up now is remarkably sensible.

I have had a tab open with the JavaCard spec for a few weeks and I continue to resist the temptation to write a JavaCard implementation for CHERIoT. Please be impressed. I honestly didn't think I'd manage this long.

Operaton users: in 2027 I'll be back at conferences and user groups to talk about the project — and for user groups I'd love to share the stage with you.

I'll cover governance, internals, what a process engine is even for. You have the interesting part: migrations, the processes you actually run on it.

No polished talk needed, 15 minutes is plenty, and we can keep the client anonymous. If there's a Java user group near you, I'll approach them together with you.

Reply or DM.
