My article about 30 years of Java and how the language evolved is now available in the english version.

It's fascinating, that old programs still run on current JVMs. The language itself has evolved since the last 30 years. From vectors to streams and the implementation of functional elements Java is everything but old. In my article I picked out some elements, that show how Java still keeps up with modern development.

So, do you still think that #JUnit 5 is "the new" thing?

It quite isn't.

The crowdfunding campaign for JUnit Lambda was ten years ago this year.

When @sormuras and I realised that last week at #JCON that made me feel old.

JUnit still rocks, though. Great #Java framework.

Oh I have goose bumps because that interview makes me happy, and very much not only because the outlook on #Java

> @JamesGosling dismissed claims by tech executives like Mark Zuckerberg and Marc Benioff that AI will reduce the need for engineers as “entirely self-serving horseshit,” seeing such statements as positioning tactics and thinly veiled threats to extract more work from employees.

In upcoming live coding streams, I'll finish generalizing the viewer to support not just any aggregate, but any custom projection (read model) as well (as long as they provide a way of getting the state as of a specific event).

Check out the #Java code: https://github.com/jitterted/jitterticket-event-sourced

On my #Java live coding stream, I'm building an example app that uses #EventSourcing, and just finished a simple "time-traveling" event viewer. The aggregate viewed here has a bunch of events (scheduled, rescheduled, ticket sales) and we're looking at state as of the 2nd event:

_Event-Sourcing Live Coding_

I've been live coding an example #EventSourcing app in #Java (via #TDD) w/o an ES library.

This week I'll continue to code the "Time-Traveling Event Viewer" to view the state at any point in time.
