Those 10,000 hours you spent becoming a great programmer aren’t useless at all. They’re what give you the two things that actually matter now: judgment and taste. Judgment is knowing when what the AI produced is correct, robust, and appropriate versus when it’s subtly wrong,

THE BIG REGRESSION My folks are in town visiting us for a couple months so we rented them a house nearby. It’s new construction. No one has lived in it yet. It’s amped up with state of the art systems. The ones with touchscreens of various sizes, IoT appliances, and interfaces

"I also get some programmers are eager to tune it out. The hype drones on, the fantastical claims are still far off, and there's uncertainty where this leaves the profession. But that's not reason to miss out on this incredible moment in human history!" world.hey.com/dhh/promoting-…

The stages of grief many developers are going through because of Claude Code + Opus 4.5 is basically what every developer who partially or fully becomes a manager goes through. For those of us already on the other side, Claude Code + Opus 4.5 is just all joy.

Remember this the next time people gaslight you with anti data center crap. Speaking of gaslighting: Canada flares off 7 GW of natural gas as a waste product of mining each year- more power than all the LLM training clusters use combined. Let’s build data centers in Alberta.

A few random notes from claude coding quite a bit last few weeks. Coding workflow. Given the latest lift in LLM coding capability, like many others I rapidly went from about 80% manual+autocomplete coding and 20% agents in November to 80% agent coding and 20% edits+touchups in

From 2020 to 2025 I often managed between 2 and 6 coop students at a time, all fully remote. I started by hiring 6 of them in May 2020, as an experiment during COVID. It turns out this was incredible training for vibe coding with Claude Code.

Dark Mode Plan (#3837) Current State (Surprisingly Good) ...so, AI has advanced far enough that it can be passive-aggressive now, even when coding 🤣

Marc Andreessen: AI coding doesn’t eliminate programmers — it redefines them. The job is no longer typing code line by line, it’s orchestrating 10 coding bots in parallel, arguing with them, debugging their output, changing the spec, and pushing them toward the right result. But

If you are a software engineer "experiencing some degree of mental health crisis", now hear this, because I've been coding for 50 years since the days of punched cards and I have a salutary kick in your ass to deliver. Get over yourself. Every previous "programming is obsolete"
