Literally just looking at pictures of my daughter from the school teacher, while an AI Agent works in the background. I have never felt like I had the time/energy/mental bandwidth to do this before.

terrific post, to which i'll add a couple of related thoughts. first: a lot of developers, especially juniors, tend to assume that other people's code is better than theirs, and so using a dependency (rather than a snippet) makes their codebase better
this is very much not the case

We recently ran a successful live failover of our control plane database from Azure West US to East US 2.
Our goal was to validate that Vercel can survive a complete regional failure of its core database.

Most annoying thing about SQL is that you can't chain WHERE clauses. Same annoyance as languages that don't allow trailing commas on lists.

JSON is widely considered a machine readable format. It’s ironic that it became a standard precisely because it was human readable. And even more ironic that LLMs are reading plain text / natural language formats now.

Scope hoisting is broken in most JavaScript bundlers, and I'm considering removing it in Parcel v3. Wrote a post about why.

JavaScript scope hoisting is broken
Modern JavaScript bundlers commonly implement two optimizations: scope hoisting, and code splitting. In this post, I'll discuss how these are fundamentally at odds with each other.

I wonder if there's overlap between the people who're really good at writing clear prompts for coding tasks and the people who're really good at writing clear git commits. Seems that prompts could be seen as writing the commit first?

if you can, avoid exporting the types of a dependency. some of the migrations we've done are such a pain in terms of backwards compat because of this 😬
