Agent OS v3 is out. Legacy codebases are a challenge in AI development. Your agents can scan your files, but not the knowledge and decisions baked in between the lines. Agent OS enhances (doesn't reinvent) what Claude Code does well. New video & docs here:

The Death and Rebirth of Programming
Programming didn't die all at once. There was no single moment, no dramatic obsolescence event. Instead, something quieter happened: the core constraint that shaped software for seventy years dissolved. Writing code stopped being the hard part.

If I put together a 2/3day Rails-oriented, indie business/small team technical leader MICRO-conference for early/mid-Jan in the UK countryside… would that sound interesting? Everyone brings one strong opinion and one problem and we take it in turns to help each other out.
