Will AI kill refactoring? My commit history says otherwise.

Repo: github.com/virtualgeniu...

Commits are 20% dedicated refactoring. No new behavior, just improving the structure of what's already there.

Speed without structure is how you build a codebase that works today and fights you tomorrow.

ContextFlow is now multiplayer.

Share a URL, edit the same context map in real time. No account, no setup. Projects sync to the cloud automatically.

Also new: drag-and-drop team assignment, DDD tooltips on every canvas element, and a visual color legend.

What is 1+1? Would an AI be broken if it gave an answer other than 2?

If you expect "2" you don't really understand how LLMs work. For at least two reasons.

A participant in an EventStorming workshop said: "..this seems quite an involved process, and this was actually the easiest one."

What I said: "The complexity was already there. We just made it visible."

Public Workshops | Virtual Genius Join our live virtual EventStorming and Domain-Driven Design workshops. Hands-on training with expert facilitation, small cohorts, and practical exercises you can apply immediately.

When multiple people add the same/similar event during EventStorming, don't immediately merge them.

The duplicates aren't noise. They're telling you something.

Have been looking forward to this talk coming out - had so much fun playing with the loopy causal loop diagrams, check it out 😀

Special thanks to @paulrayner.bsky.social for feedback and advice the night before this one! @dddeu.bsky.social #systemsthinking

In this talk Chris Simon will demonstrate the building of a range of causal feedback loops to visualise the underlying causes of the problems. With such visualisations we can advocate for the practices of technical excellence:

Curious what unexpected connections, ‘aha’ moments, and opportunities will emerge as the shared story is visualized on the wall.

That's when I reach for the ESC key :)

Yes, one of the Claude Code agents is "test automation specialist"

No. I'd not even heard of it. Fascinating!
