Identity has become one of the most important control points in modern systems. As applications grow more distributed and AI-driven automation becomes part of everyday workflows, identity increasingly defines how secure, predictable, and trustworthy those systems are.

The year that brought us modular Rust libraries, faster DAG-CBOR, stable multiformats, and a simpler on-ramp with DASL.

I’ve now been through three approaches to load testing for the site, and I think I’ve settled on a solution for the medium term at least.

At one point copy and paste was a technological marvel. Eventually it became a development pattern. Blindly copying snippets from around the web into text editors or riskier, directly into your terminal.

You can use Polecats without the Refinery and even without the Witness or Deacon. Just tell the Mayor to shut down the rig and sling work to the polecats with the message that they are to merge to main directly. Or the polecats can submit MRs and then the Mayor can merge them manually. It’s really u...

On January 15th 2026, Robert Jenrick broke my election site. Okay, that’s slightly hyperbolic. The site continued to operate, and it would be fairer to say that the actions of Kemi Badenoch and Robert Jenrick exposed a flaw in the data modelling in my site. For those readers who don’t follow UK poli...

One of my oldest open-source projects - Bob - has celebrated 15 a couple of months ago.

I demoed a Python MCP server that uses Microsoft Entra for authentication, requiring users to first login to the Microsoft tenant before they could use a tool. Many developers asked how...

How often have you heard about the speed of Python? What's actually being measured, where are the bottlenecks---development time or run time---and which matters more for productivity? Christopher Trudeau is back on the show this week, bringing another batch of PyCoder's Weekly articles and projects....

Abstract You’ve vibe-coded an AI assistant that’s a game-changer for your team. It works perfectly on your laptop. But when you try to deploy it company-wide, everything falls apart. This is what is known as “deployment slop”—the messy reality when quick AI prototypes hit the enterprise world. Your ...
