What is a Command Bus? If you haven't encountered a Command Bus before, or not quite clear on it's purpose - this might help you develop an easy way to think about them. youtu.be/pXVZhFE2pbk

What can we learn about Software Development from Retro Games? As it turns out... quite a lot! Sharing a teaser for the upcoming video:

Accidentally discovered some funky behaviour when running an artisan command - and I recommend you avoid using it!! 😅 youtube.com/watch?v=gCQRhX… #laravel #php

Playing around with an idea to visually explain Partition Tolerance. Thinking about doing a more in-depth video about CAP Theorem, how it can be used as a design tool for distributed systems and how #CQRS relates.

Understanding CAP Theorem is important when designing distributed systems. CQRS can avoid the limitations of CAP Theorem by splitting Reads (optimised for Availability) and Writes (optimised for Consistency) into different systems. youtube.com/shorts/DxywRiK…

Fascinating talk by @UdiDahan at @NDC_Conferences: "CQRS pitfalls and patterns" - particularly interesting perspective on Public/Private Responsibility Segregation. learncqrs.com/bOi45N

Wrote an integration test, got 3 people educating me why unit tests shouldn't touch the database. How is your day going?

This guy is gonna be talking about #DDDesign and #CQRS soon. Maybe even a little #EventSourcing! youtube.com/@andrew.cairns

Working with a legacy system presented some challenges with transaction boundaries. Be mindful of consumers with side-effects. More in my devlog: youtu.be/y67hTtS37yw

Shitting on SOLID has become too popular. Which principle are you so against and why? Do you like objects w/ many responsibilities and reasons to change? Modifying stable code to add functionality? Perhaps you love large interfaces? Or new'ing within your classes? You do you.

Making your Application Stable with the Outbox Pattern. In this article @DariuszGafka discusses the advantages of the Outbox pattern and why you want to persist your events at the same time as other state changes. learncqrs.com/vY7A3z

In this article, I explore what ACK/NACK protocol messages are and how they can be used with #CQRS. acairns.substack.com/p/acknack-for-…

@boyney123 Marvel Snap uses CQRS, event sourcing, recomposing on client. Only within a 1v1 game session, and pinned to a version. We avoided schema versioning problems that way. IME it's great for short lived uses or archival-only, difficult if long lived + you plan to interpret the events.

Bringing idempotency to a distributed reactive system is a considerable challenge. What do I mean by idempotency treatment? Absolutely is not a message HASH or GUID control. Modeling Uncertainty is the more efficient way to deal with this... #DDDesign
