FreshMarker Variable Scope Revised

The blog posts on the FreshMarker template engine pursue several goals. On the one hand, the posts should of course entertain their readers. On the other hand, they also serve me to focus and document my ideas on various aspects of the implementation. One very interesting topic in

Hear from host @maritvandijk and me as we kick things off to celebrate 30 YEARS OF JAVA!

Today I learned one can create an alias which executes a custom #java function via #sql in a #H2 database. Combine this with a #springboot or other application allowing #sqlinjection and "oops, compromised". Lucky for me it was only an exercise and not in a real application.

Someone else wrote about it: https://medium.com/r3d-buck3t/chaining-h2-database-vulnerabilities-for-rce-9b535a9621a2

And here are the official docs: https://h2database.com/html/commands.html#create_alias

I truly miss the days I did not know of such things...

Happy Birthday, #Java! Here’s to 30+ more years with a beautiful combination of technology innovation and community participation!

Java turns 30 today 🎉🤩

What a journey – from being a #Java tutor at university in the '90s, authoring a book on Java for Mac OS X some 20 years ago, delivering Java trainings and workshops for over 2 decades, to being a technical coach using and promoting the latest Java features.

Happy birthday! Here's to the next 30 years!

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:

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.
