I just sent the March edition of my sponsors-only monthly newsletter (https://github.com/sponsors/simonw/). If you are a sponsor (or if you start a sponsorship now) you can access it here (https://github.com/simonw-private/monthly/blob/main/2026-03-march.md). In this month’s newsletter:

• More agentic engineering patterns

• Streaming experts with MoE models on a Mac

• Model releases in March

• Vibe porting

• Supply chain attacks against PyPI and NPM

• Stuff I shipped

• What I’m using, March 2026 edition

• And a couple of museums

Here’s a copy of the February newsletter (https://gist.github.com/simonw/8b5fa061937842659dbcd5bd676ce0e8) as a preview of what you’ll get. Pay $10/month to stay a month ahead of the free copy!
