LIVE CODING STREAM THIS WEEK
After an awesome time at #ExploreDDD, I'm back home and ready to continue working on JitterTix, the example #EventSourcing app in #Java, #TDD, a tiny bit of #SpringBoot and no other libraries (well, a few small ones, but not for the EventSourcing).
We released 3.11.0 of event-sourcing-bundle! See here for the changelog: https://github.com/patchlevel/event-sourcing-bundle/releases/tag/3.11.0

I just published the third of a planned five-piece series on my enjoyment of #eventSourcing in #Python.
This one digs into the software industry's problem with coupling and how my switch helps relieve unwanted coupling.

Had finally time in the weekend to write a new blog post about the new features for our latest releases of patchlevel/event-sourcing. So if you want something to read for the weekend you can check it out here: https://patchlevel.de/blog/what-is-new-in-php-event-sourcing-3-9-and-3-10
Discover the power of #ShadowTables in real-world migration scenarios!
From DB migrations to service extractions & schema changes, this #InfoQ article compares Shadow Tables with dual-writes, blue-green deploys & event replay.

_JitterTix Concert Ticketing System_
On my #Java live coding stream this week I've been working on a simple concert event ticketing system that is based on #EventSourcing. I have several reasons I've been doing this (putting my #TDD Game on hold).
One of the benefits of #EventSourcing that continues to come up is the ability to answer questions that you didn't originally have when creating a system.
With a state-overwrite system (aka non-event-sourced), you lose the trail of changes unless you explicitly build it in.
This afternoon's #eventsourcing and #ruby hacking: improving the DX for scheduling new commands as a reaction to past events.

We released 3.10.4 of event-sourcing! See here for the changelog: https://github.com/patchlevel/event-sourcing/releases/tag/3.10.4
#PHP #DDD #EventSourcing
Stealing some more time to work on #eventsourcing error handling in #ruby as well as stopping and resuming workflows. In this example, resuming a stopped consumer group continues pending "send to Slack" workflows from where they left off. https://share.cleanshot.com/YjJJWcBd
Playing with error handling and retry strategies for eventually-consistent #eventsourcing workflows in #ruby. In the example, buggy projector retries processing an event with exponential back-off, until it gives up and stops the entire consumer group.
#EventSourcing was portrayed as hard, complicated, and impractical. The reality is actually opposite, and that's what I wanted to show in this recording.
You'll find a hands-on guide showing Event Sourcing in practice. You'll learn step by step:
-What’s Event Sourcing,
-How to model and tell the story about your business process using events,
-How to reflect that in the code, so modelling events, command, business logic,
-How to test Event Sourcing business logic with Behaviour-Driven Design,
-Joining that into REST WebApi,
-using PostgreSQL based storage,
-build read models.
I showed that using Node.js, TypeScript and Emmett as I believe this can make it even smoother!
What's Emmett? Emmett is a framework that will take your applications back to the future.
The idea behind Emmett was to make it easier to create business-focused applications and cut unnecessary code without using magic. The combination of using events and their business focus, the expressiveness of TypeScript and the lightness of Node.js is supposed to help with that.
All of that is in a 1.5-hour webinar. So fasten your seat belts, watch the recording and tell me what you think.
