The worst AWS service isn't public. It's Isengard -- the internal tool that means Amazon's engineers never have to manage AWS the way customers do. If they had to live that pain, it'd get fixed. Open source it or stop using it. duckbillhq.com

Built an agentic EA to handle vendor pitch emails. Technically professional. HR couldn't fire someone for these responses but they'd be having some very uncomfortable conversations. Never felt more alive.

If your website has a chatbot because your website isn't doing its job, that's a website problem. AI support works when it routes to a human fast. Most deployments are a gauntlet instead. duckbillhq.com

Vercel: $10B company, built entirely on AWS, 20-30% markup. Hyperscalers are becoming power grids. Everything depends on them but that's not where the interesting stuff is. Unlike PG&E, AWS still wants credit for what its customers build. duckbillhq.com

The thing that frustrates me most about cloud isn't the pricing. It's that we've forgotten how hard this is. Easy became the assumption. That assumption is where expensive surprises live. duckbillhq.com

"Cloud is too expensive, let's build a data center." If your engineering team hears this and doesn't immediately look ill, they haven't done this before. An AZ is a data center. You're not simplifying. duckbillhq.com

free: billie roasts at normal intensity, you cannot fire the platypus

Nice one and gives you proper FS interface - they didn't slap some half solution on top of S3 and it's actually syncing S3 <-> NFS and both work as expected.

Recently a friend got on some new meds that made them much more chilled out, but to the point that they're procrastinating tedious and boring (but important) tasks, and it made me think about how much of my productivity is just white hot free-floating anxiety.
