One of my fun programs ever was figuring out the various parts of a typeface, which I could only do by writing the WinForms program (it was another age : ).

After losing Mint and Personal Capital, and now Empower is moving my cheese again, I needed a stable place to track my accounts. Then I found @SimpleFin ( https://t.co/GpsI9WAmVh). And since I wanted to build my own apps, I built simplefin_dart: https://t.co/el1TEItq8z Enjoy.

Has anyone tried Zed? I resisted it but am really liking it, especially how they do AI coding agents via the Agent Client Protocol. If it supported Flutter the way VSCode did, I think I'd switch.

I just shipped dartantic_ai 1.2.0: https://t.co/aLQZQZ8EiR - Migrated Google provider from deprecated google_generative_ai to Google-supported google_cloud_ai_generativelanguage_v1beta package, fixing some low-level response issues. - Added Google "double agent" orchestrator to

Been using AI coding agents for a while? Then watch this video to have Lada Kesseler turn your niggling suspicions into "I knew it!"s: https://t.co/MTmn7Sh7iU Lada has pulled out the Gamma-style patterns out of coding agents. #recommended

TIL about AutoGen, Microsoft's version of pydantic-ai: https://t.co/9CFDBAYRNy Lots of good ideas in there about agentic workflows. I believe that AutoGen has since been superseded by the Microsoft Agent Framework:

I have a habit of emailing myself links for things I want to research and then don't, since there are too many amazing things to research these days. I experimented with n8n to watch for new email and reply with the research for me, but never made it past the 2 hours of install

Dartantic v1.1.0 is out and this is a big release! The big news is the new OpenAI Responses provider built on the openai_core package, including session persistence (aka prompt caching), intrinsic server-side tools, and thinking metadata streams. Thanks to @jezell for his most

I'm busy working on a new dartantic release and as part of that, Sonnet 4.5 runs examples like this: `DARTANTIC_LOG_LEVEL=FINE dart run server_side_vector_search.dart` This was surprising, since dartantic had no environment check for a logging level. But now it does. : )

Been spending a bunch of time with Gemini 2.5 Pro for coding this weekend. It's about 80% as smart for coding as GPT5 and Opus 4, but when I use it, I can't juggle between multiple agents on different projects: 2.5 Pro is too fast! Not a bad tradeoff to be honest.

Holy cow. Somebody thinks that I'm in the top 1% Dart engineers in the world. I do love Dart! https://t.co/Sn6elExkwM

I used to get up in the morning and deal with my messages. Now I check the progress of my AI agents and direct them to the next step, while my messages go unmanaged. AI just feels more creative and fun.

TIL not to use AI to code a protocol client and server in the same project at the same time, as it will surely route around the protocol restrictions to get things working. Instead, build the new server/client against known working implementations first. This is the way.
