An MCP server is not a new API. It is a thin layer over the one you already have
Somewhere in the last year, "do we need an MCP server?" joined the list of questions that arrive in a brief before anyone has said what the thing is for. It is usually framed as MCP vs API, as though the Model Context Protocol were a newer kind of AP...

Tuesday Isn't a Valid State Transition
Calendars, evidence, and the difference between done and stuck I expected my pear wine to spend two to three weeks in primary fermentation. It spent nineteen days. The yeast went in on September 23, and on October 12 I siphoned the wine off its sed...

Log Safety Events, Not Full Transcripts: One Audit Trade-Off
The FTC's inquiry into consumer AI products has turned a question most teams deferred into a launch requirement: can you show what your product actually did? That answer depends on a logging decision you make before launch - and can't retroactively f...

Six agents were running and I could not tell you what any of them did
Six coding agents were running. I could not tell you what any of them had done. Not roughly. Not approximately. The output was there, the files had changed, and the honest answer to "which one did that" was a shrug. Three questions in particular had...

AWS's Own Dashboard Could Not Say It Was Down. Four of Our Monitors Had the Same Bug.
A signal has three states and most code stores two. When “cannot measure” is written with the same value as “fine,” the alarm branch becomes unreachable in exactly the situation the alarm exists for. On 7 December 2021, the operations teams inside...

21% of IT Leaders Can't See Their Own AI Agents. I Fed 11 Checks Empty Input; 5 Passed in Silence
In a 2026 vendor survey of 750 IT leaders, 21.1% said they could not account for shadow AI agents. A better dashboard will not fix it: a 1978 stroke study shows why, and eleven of my own checks proved it. In one 2026 vendor survey of 750 IT leaders,...

How to Deploy an Open Source LLM Reliably (on Kubernetes)
