This is not easily parsed by machines (or even humans). Some version numbers are on the same line, others are on a separate line.

There's extraneous and unneeded info.

And there's no way to influence the appearance of the output. For example, the ps command as the -w flag to explicitly set wide text output mode.

Another stream, another set of notes. So much "new"!

I try out a new design for Projectors, splitting EventConsumer into two pieces. Test-driving shows how it's about design exploration, not just writing tests.

#Java #EventSourcing #TDD

Notes from my #Java #EventSourcing work, where I looked at event consumers that only get events they're interested in.

Struggled with Java's MethodHandle (docs could be better!), but otherwise works well.

Thoughts about Projector design.

This was all triggered by new functionality that I want to add: the ability to set a date/time when concert tickets go on sale that is separate from when the concert was scheduled (entered into the system).

Want some Technical Coaching or a #Java Talk (Event-Sourcing, Testing)?

I'm looking to do meetup/user group presentations or technical coaching the week of April 27, and in June so I don't have to fly all the way back home, just to fly back again a soon after.

I love #Java generics (when I get them right, which can take me a while!) and find varargs really useful when refactoring, but they do NOT play well together. Ugh. Guess I'll create an overloaded method to take a List<T> instead.

On my #Java stream last week, I had some frustration with Avro for event payload serialization and decided that JSON was just fine (in terms of performance).

I had thoughts about Projections as Caches and a question around IDs being required in events.

#Lisp people, do you have a preference for the name 'hashtable' or 'hashmap'? In #Java, there's an actual semantic difference, since Java HashTable is not thread safe while Java HashMap is.

I am building things which are thread safe. My inclination is to call them 'hashtables', but is this now old fashioned and should 'hashmap' be preferred?

If so, please give reasons.

Technische Schulden sind eines dieser Begriffe, die du früh hörst und erst später wirklich spürst. Gemeint ist kein “Fehler”, sondern eine bewusste oder unbewusste Abkürzung im Code oder in der Architektur, die dir heute Zeit spart und dich morgen Zeit kostet. Wie bei einem Kredit: Du bekom

More live coding #Java and #EventSourcing:

I dealt with "external" and "parameter" validation (I didn't implement the third type: "internal" validation) of scheduling conflicts for Concerts.

I also pondered minimal consistency boundaries.

Notes are at: https://ted.dev/articles/2026/03/24/live-coding-journal-mar-24-2026/

Back to streaming, with notes from yesterday's stream: https://ted.dev/articles/2026/03/23/live-coding-journal-mar-23-2026/

I chatted about consistency boundaries, missing-event heuristics, and encoding (serializing) events.

The Scripting Dilemma If you're like me, as a Java developer, you struggle to remember bash or python syntax for quick scripts. You end up "vibe coding" it, then struggle again when you need to adapt it. If only you could write it in Java! You might say "Java is not for scripting" and "I…...
