It’s pronounced `ten-yay
There are only two reasons for me to care if someone is left-handed:
1. they’re a pitcher for the Blue Jays
2. they’re seated to my right at a steak house
every now and then i remember, dimly, that my first grade teacher tried to force me to stop being left handed. my mom and i used to get school supplies at a left-handed store. everyone i knew seemed to comment on me being left-handed.

that all stopped when I was 10-11, no one seems to care now

my feeling is that if we are going to let AI loose we should start simple and low-risk, like criminal profiling, autonomous driving and medical advice before we let it handle complex tasks
It’s crazy the sheer number of supposedly rational people who were like “ok but it’s good at health stuff” early on.
When AI was added to a tool for sinus surgery: “Cerebrospinal fluid leaked from one patient’s nose. In another… a surgeon mistakenly punctured the base of a patient’s skull. In two other cases, patients suffered strokes after a major artery was accidentally injured”

We recently ran a project to help Knowunity cut their LLM bill by half. It’s pretty cool to beat a frontier LLM (Gemini) on all dimensions, which matter: cost, speed, and accuracy by trading off generalization, which is unnecessary here.

How Knowunity used distil labs to cut their LLM bill by 50%
We show how Knowunity use the distil labs platform to fine-tune and deploy their own models, significantly reducing their LLM costs.

Some context from that Lays ad.

People are very stupid and don’t realize that potato chips are literally made out of potatoes.

That’s why they were parading around a potato in that ad like it’s the fucking Rosetta Stone.

Just shove it on Marc Andreesen’s head and it’ll be good as new
The crown of Empress Eugénie was one of nine invaluable royal ornaments snatched by burglars during the Louvre heist in October, but the thieves dropped it on the sidewalk before making their escape. The Louvre announced it will soon invite restorers to submit proposals for the crown’s repair.

A traveler from an antique land--great guy--said to me with tears in his eyes "Sir, two vast and trunkless legs of stone stand in the desert." And I said wow, that's really something. But we'll be building a big beautiful statue to my hubris and it will stand for eternity

I’m working on an idea I’m calling “AI Psychosis by Proxy” whereby the more you read about how people are talking about their AI “agents” the more you feel like you’re the one going insane.

DOCTOR: I told him he needed to get out to a show, that was how he would cure his depression.

CHOTINER: So you learned this technique in school?

DR: No, not— listen it was good advice. Pagliacci was in town.

C: Right. Is it standard to give advice before learning a patient’s name?

DR: Now look

I want to get the word out not just because @grodowski.bsky.social is a friend and former colleague but because I think it's a tool a lot of Ruby devs would really benefit from but won't get talked about because it's not "glamorous". It does one thing incredibly well and we need more tools like it.

Big shout out to undercover-ci.com the code coverage tool we use at @rainforestqa.bsky.social. It's always been great as a pre-release gut-check but lately it's become absolutely *essential* for ensuring our AI agent-written PRs have the coverage we require.
