A rewrite starts with confidence. The old code is messy. The new code is clean. Then production begins teaching the new system everything the old one already knew.

I'm having more fun than I've had in a long time. (link in 1st comment)
@mitsuhiko It’s the warmup for the upcoming quantum issue tracker, Schrödinger’s Issues
Most software architecture assumes the implementation is the system. That’s why rewrites fail. The implementation contains years of accumulated memory: edge cases, operational lessons, regulatory constraints, production discoveries, failed experiments, and hard-won invariants. The code runs the system. The memory is the system

I'm slowly but surely forming a better idea how to do "better specs". The key idea is to make them structured and allowing a spec to contain structured source of truth definitions and rich artifacts such as code-defined diagrams, API/CLI/schema definitions, etc.
@sternhenri I'm spending a considerable amount of time thinking about how this applies to software generation aicoding.leaflet.pub. (also writing a not-yet-announced book for a publisher on the topic)

AI Native DevCon is live. After an opening keynote from Simon Maple ( @sjmaple ), Guy Podjarny ( @guypod ) has just taken the stage with "Skills are the New Code". As software development shifts from writing instructions to defining intent, skills, specs, and context are becoming the core building blocks of modern engineering. If you're building AI-native systems, this is exactly the conversation happening right now. Can't join us in London? Watch live from anywhere: youtube.com/watch?v=akZ85m…
@samaaron @josevalim How do we meet again

The skills you worked hard to develop as a programmer are just as valid today in the world of AI agents. Link below.

One of the more fun conversations I've had in a while. @guypod and I went deep on regenerative software and the Phoenix Architecture. Give it a listen!
@swombat same. in an era of tons of copy/paste, it is clearer than ever how insanely stupid white space sensitivity as language syntax is.
When you hand an LLM a coding task and don't tell it what language to use, what does it reach for? I wrote a tool to find out. Help build it out!
