Working with my 8 year old on designing a game to teach him how to type has been a good counterpoint to LLM induced anxiety and dread.

So far, Fable is the only model to take my "reply to me like you are Carmy from The Bear" comment in my Claude file seriously. However, it does not pick up on my The West Wing references. So, there is still room for LLM improvement.
I needed a world map for a project. Asked Claude to render one. I wish I didn't.

I really don't remember the last time I had a workday that wasn't interrupted by a third party incident of some sort. Time to refresh that XKCD.
This post from @josevalim.bsky.social is such important context for anyone trying to evaluate the performance of LLMs. They're super useful in lots of cases! ...but they're absolutely a hindrance in many others. nitter.net/josevalim/st... #ElixirLang

Today I was reminded of one of my favorite pages on the internet. wiki.c2.com?PokemonExcep...
My not so humble opinion in dealing with Security Architects and Spdcialists over four decades is that many hold users in contempt and do not care that their products and solutions are painful to use.
Why do the Japanese like their buns askew (2026)
39 seconds into the Clojure documentary and I can already tell that this is going to be amazing.
I’m nostalgic for the days when the grift was behind closed doors.

Thanks to the increased productivity with AI, we can finally spend more time in Scrum meetings
I just released a lil @elixir-lang.org library for generating docs about telemetry events from structured data. Love me some telemetry events but they're often an underdocumented aspect of libraries. hex.pm/packages/tel... Feedback welcome 👐

Tired: AI won't take your job, but someone using it will. Wired: AI won’t take your job, bad management decisions wrapped in an AI trench coat will.
When Claude writes test first: HAHA YES THIS IS GREAT When Claude goes off the rails, spits out code, pretends tests don't exist: Listen here you little shits.
OpenAI published a repo to orchestrate AI agents built primarily with Elixir (96.1%): github.com/openai/symph... #elixirlang

One of these days a bloom filter is going to be the solution to my problems. Today is not that day.
My 7 year old introduced me to the phrase "chicken nuggets for brains" and I've never had a phrase enter my daily usage so quickly.
Highlighting the speaker who stood in front of the Surprise mayor and told him to consider what the Mayor of Ohrdruf must’ve thought before he died by suicide: “He might have thought ‘how is this my fault I had no jurisdiction over this’ maybe he said ‘this site was not subject to local zoning.’”
Ripping a Lilo & Stitch cd so I can put it on my iPod while waiting for Claude to finish a task is apparently something I do in 2026. What a weird timeline.
Labels not including track metadata on newly manufactured CDs has to be some of the laziest shit I've seen in awhile.
Buying physical media every time I read an article on AI written by three LLMs in a trench coat is a fun new way to play "markets can remain irrational longer than you can remain solvent".
Claude Code has greatly decreased the amount of time it takes me to go from idea to abandoned project.
A long known irony of automation is that as you automate the most frequent (and easy) cases first, people are left to handle both increasingly rare *and* challenging situations, with less practice.
If you didn't like content written for SEO, boy are you gonna hate content written for AI.
