If anything, the constant pivoting and re-pivoting to build an AI narrative has probably slowed down the delivery of real value while increasing noise and feature churn.

The management and incentive thinking I hear from top VCs today sounds like it came straight from an IBM middle manager running a mainframe payroll system in 1987.

I asked Pi to play Warcraft sounds, thought it would use one of the extensions out there. forgot about it. later I’m in another terminal and get spooked by a sudden “Yes me lord” in the weirdest voice.. turns out it couldn’t download the original files so it used the Mac say command to recreate them

It’s sad that, in the rush to call themselves AI-enabled, companies are reverting 50 years in software engineering and doing silly things like counting LOC, like a middle manager at IBM on a CORBA project in the ’90s.

It’s going to be so damn funny when these bots and the folks hyping this AutoGPT 2.0 as the second coming realize what the second L in LLM stands for…

What phase of the bubble is it when JetBrains is wheatpasting AI ads in a sleepy Carroll Gardens corner. someone’s about to switch IDEs on the walk to get fresh mozzarella from Caputo’s?

I can’t recommend this video enough for those of us who are trying to get a good idea of what could happen in the next decade. It made me feel like 20 things at once. And it features Stanford Beer, the OG cybernetics guy! youtu.be/AYGt_UN0DpM...

I don’t find Inngest particularly interesting as a durable workflow framework , but it tickles my programming language nerd brain that TypeScript is such an utilitarian language that things like these are idiomatic without much syntactic sugar

If your emacs went completely mad with setting/activating the mark a while ago, this is the culprit: MacOS at some point seized C-spc Took me a very long time to debug, LLMs took me down useless rabbit holes and the correct answer was on StackOverflow from six months ago.

Famously, Burning Man was like an electric fence that kept SF free of startup bros for a week. But life finds a way and the raptors learned how to open doors.

The title of first talk in the RailsConf 2025 playlist tells you a lot about how Ruby and Rails are stuck in the early 2010s.

I’m always skeptical when people use this “mind virus” stuff, but the point is my man’s not rejecting RAG. He’s just using grep instead of vector search for retrieval, which is extremely common. I’d recommend he look into language-aware semantic search as the next step in his RAG journey.
