I'll make this even more simple: Many (most?) of us in the security engineering world who have taken even a cursory look at this browser would advise colleagues & friends to avoid it at all costs. It's a privacy and product security dumpster fire.

A DHH post I agree with. I wish more US employers offered sabbaticals as a benefit.

New blog post, reflecting on nearly seven years since the Firecracker launch, and how we're using Firecracker to power serverless databases (in Aurora DSQL) and infrastructure for AI agents (in Bedrock AgentCore).

The best years of your life are ahead of you. Also: don't overthink everything. You really can't control things, not even if you become a billionaire, look how crazy they go trying. Live, do your best day to day, be kind to yourself, and don't put things off hoping for the perfect moment.
