Managing context in long-run agentic applications
Excerpt In complex, long-running agentic systems, maintaining alignment and coherent reasoning between agents requires careful design. In this second article of our series, we explore these challenges and the mechanisms we built to keep teams of agents working productively over long time spans. We p...
Alan Turing play in Cambridge MA
Last night I saw Central Square Theater’s excellent production of Breaking the Code. It’s about Alan Turing, who made a monumental contribution to both my profession and the fate of free democracies. Well worth seeing if you’re in the Boston area this month.

These too...
Graceful degradation in Postgres
Not all traffic is created equal.When a database is overwhelmed, you want the important queries to keep executing, even if that means shedding lower-priority work.This is a much better outcome than the alternative: a total database outage.
