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. Free OSS: contextflow.virtualgenius.com

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. virtualgenius.com/blog/what-is...

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." I'm teaching a public virtual EventStorming workshop April 14-17. virtualgenius.com/workshops/

@dddeu.bsky.social is a must-attend event for anyone serious about software modeling & design. Plus, it's in the heart of beautiful Antwerp in June! This year I'm teaching context mapping hands-on using ContextFlow, my new OSS project. virtualgenius.com/products/con...

Claude Code says it's done executing the Supabase/Stripe integration implementation plan. I clear the other CC session and have agents review *actual* progress and update the plan doc.

I’ve been working exclusively in Claude Code lately. For new features, I've typically spent no more than half a day (usually much less) drafting a plan in “planning mode,” then let it evolve as I build. Small slices, lots of iteration and learning.

After 6 wks of tinkering in Bolt.new and Claude Code, I’m down to the last mile before releasing BINAH, my passion project. Integrating paid subscriptions via Supabase + Stripe. Launch coming soon!

The entry in my claude.md that makes coding just that little bit more fun for me 😎 - **Task completion**: Always `say "Done"` when completing significant tasks

Experimenting with working with Claude Code in VSCode in two different sessions simultaneously, each working on different parts of the code base. I've been toggling between plan mode in one session while the other implements. It feels smooth so far. How has this approach worked for you?
Trying out Claude Code in VSCode with two sessions at once—one in plan mode, the other implementing. Switching between them works smoothly so far.
