Two new AI tells I'm seeing everywhere lately: • "Two x, One y" (e.g. "Two Sources, One Shared Trait") headlines. • "Eyebrow" text above every headline (e.g. "The Studio" text in the attached screenshot).
Screenshot of a AI-generated web page layout.

Eyebrow header text: The Studio

Header text: Hive was built for the kind of unhurried appointment that's becoming hard to find — a quiet room, real coffee, a conversation before scissors ever touch your hair.

Body text: Founded by Ava Marin in a converted bungalow off Plant Street, the studio takes its name from the small, devoted teams of artisans she trained with in Milan. The work is collaborative. The room is calm. The clients are seen by name.

Everything we use — from the low-ammonia color line to the bond-building treatments to the chairs themselves — was chosen for the long view. Hair you can grow out gracefully. A space that ages well.

Google finally updated some of its satellite images of Gaza and my god, it's horrific. The entirety of Rafah has been demolished. The majority of Khan Younis is in ruins. Entire towns completely leveled and erased of the map.

Both the women's and men's World Championship races were stellar this year. They should probably just hold them in Montreal every year from now on.

A woman in a colon cancer support group I belong to posts about four of these a day. While I'd usually scroll right past them and roll my eyes, I'm genuinely happy for her. It might not be high art, but it's clearly bringing her a lot of comfort.

I'm a bit of an anxious patient at the dentist, so I tried doing breathwork during my appointment yesterday. Ended up so relaxed that Oura thought I was taking a nap.

The best/worst part of waiting over an hour in the rush line to see John Wilson's The History of Concrete (and not getting in 😭) was telling passerby that yes, we were all standing in line to see a documentary about concrete.

I do worry that frontier models will end up locking us into today’s languages and libraries. Why build new software infrastructure when coding agents are dramatically better with the tools that already have millions of examples in their training data?

OK, Siri is really good now.

The user then asks, "What was the previous iPhone I purchased?" and Siri correctly identifies it as an iPhone 15 Pro, providing the purchase date. (This alt tag was also generated by Siri)

I'm sorry but this show is criminally under-appreciated. Easily in the top 10 of the century so far. I should start a rewatch in protest. www.nytimes.com/shared/v1/cl...

96 HALT AND CATCH FIRE
2014–2017

This drama began in the early days of the personal computer revolution — before social media, before FOMO, before A.I. angst — to tell the story of a quartet of tech pioneers who looked at those clunky beige desktop boxes and saw a kaleidoscopic future. Computers were “the thing that gets us to the thing,” the latter thing being connection, empowerment, even a new kind of art. What began as a familiar tale of business-suite intrigue — “Mad Men” with processors — became a rich, heartfelt, human exploration of the costs and rewards of work and the necessity of failure. Its portrait of ’80s and ’90s techno-optimism may seem quaint now, but its rendering of the love of creation remains bleeding-edge. — James Poniewozik

Found an AI slop genre that infuriates me even more than AI restaurant images: concert posters. Even though this is only a local bar band of middle-aged dudes likely happy to just get out of the house, concert posters have such a rich history. It would be sad to lose that to slop.

Thinking about moving because my neighbourhood makes it hard to justify buying an e-cargo bike. My grocery store and local restaurants are 400m away, doctor is 600m, even my weekly hospital visits and the lakefront are only 1km through the park. High Park is TOO convenient of a neighbourhood!

I don’t understand the hand-wringing reaction to claims that nueral networks have a 10% chance of destroying civilisation. Fossil fuel companies have a 100% chance of initiating a mass extinction event. Maybe we could address that?

Good rules by Robin Sloan for using AI to build personal software (which everyone should be doing, it's a lot of fun). www.robinsloan.com/lab/ask-for-...
Rules for personal software produced with the help of AI agents:

1. You must actually and consistently use anything you build for two months before posting about it.

2. Ideally, never post about it. (I know I am breaking this rule, but my purpose is pedagogical, and anyway, I’ve got more apps I didn’t tell you about.)

3. Don’t let the AI agent name the app. You pick the name.

4. Don’t distribute the app, not even for free. Don’t post the code on GitHub. This is not software for glory; it is software for you.

I really wish AI doomers would look more at the Industrial Revolution and 20th-century automation to see how AI adoption is actually likely to play out. We're very much in the "where does the steam engine go" phase of things right now.

Had a call with a bike shop today about a project, owner mentioned that he used to work in tech. Me: "That's funny, opening a bike shop is my escapist career fantasy." Him: "It was mine too. Now my fantasy is selling the shop and going back into tech."

Honestly my most lasting memory of 9/11 is going to the record store in my small college town first thing in the morning and buying what turned out to be one of the defining albums of my life, then walking around listening to it all day and not realizing that everyone around me was freaking out.

People who are aren't trying to push models to the limit really underestimate the power that's already available in today's public models. The reason people at frontier labs sound insane is because they see what's possible right now, but no one outside the labs is productizing those capabilities.

Half-baked AI thought: Are frontier models approaching the limits of capabilities with today’s coding languages that were designed for human devs? It would not surprise me if a lab introduces an AI-native programming language in the next year optimized for LLMs, but unusable by humans.

Every Sunday people at a church in my neighbourhood park on the sidewalk because they don't want to use the public lot half a block away. Today I finally got to unleash the "jerk store" line I've been workshopping for weeks against one of them. It went about as well as George Constanza's attempt.

You really have to hand it to mitochondria’s PR team. “The powerhouse of the cell” has to be one of the most successful branding campaigns of all time.
NYTimes article text: Psilocybin, they found, protected the microscopic nerve endings that detect touch, pain, temperature and pressure. At the same time, psilocybin preserved the ability of mitochondria, the “powerhouses of the cell,” to deliver energy to far-flung nerve endings, ensuring their survival.
