Welcome back to The Catalog. Here’s what’s worth learning, exploring, or watching this week, so you can start with a shortlist instead of sifting through noise.

NEW ARRIVALS

01 · Commodore is Back with a Y2K-era Flip Phone

Commodore, the company behind the Commodore 64 and most of the 1980s home computer boom, collapsed in the mid-1990s and passed through a chain of owners until a YouTuber bought the brand last year.

Its first product release in decades is a flip phone that very intentionally does not have a web browser, social or work apps. The Callback 8020 ships at $399.

Commodore says other phones are cheap because they harvest data, and they call their streamlined new phone a “speed bump for your mind.” The Commodore brand is a name someone bought, and the phone is a list of things it won’t do. I’d still like to live in a world where using this day-to-day makes sense.

02 · Quitting Anthropic with a Public Warning

Jacob Coxon made waves after he resigned from Anthropic on September 8 and posted his rationale to X. His posts drew 153 million views in 36 hours. He left with equity two months from vesting, and wrote that neither Anthropic nor OpenAI is acting responsibly in this artificial race to AGI.

Headlines have propelled him into the spotlight. In a video interview with CBS, Coxon talks about his decision to resign and why he feels AI could one day threaten humanity. He says the major AI labs “are racing straight to self-improving superintelligence and gambling with our lives.”

Leaving two months of vesting on the table is a stronger signal than 153 million views.

03 · Hot Hot American Summer

The National Oceanic and Atmospheric Administration (NOAA) confirmed that June through August was the hottest summer on record for the contiguous United States. It beat the previous records, set in 1936 and 2021, by 0.4°F, and ran 3.0°F above the 20th century average. Records like this usually fall by hundredths of a degree.

The drought stats surprised me most. Almost 60% of the country was in drought by September 1, a jump of 10 percentage points in a single month. Arizona, New Mexico, Utah and Colorado all set or tied summer records, which puts the worst of it squarely in the Southwest.

The records this summer broke belonged to the Dust Bowl.

THE FEATURE

Canyon Grooves: The Difference Six Months Makes

I have been waiting all week to show you what I built here.

Canyon Groove plays the actual topography of a canyon as generative music, and it only took me two nights to build.

Earlier this year, in March, I was scrolling through Reddit and a photograph stopped me and made me think. It was a close-up, magnified view of a vinyl record player’s needle in the groove of a wax album, with the left and right channel walls labeled on either side. As I stared at the photo, I thought it looked like the vinyl needle was dragging through a canyon.

That simple thought drove me to build a system that plays music for each famous canyon. I opened Claude Code the same afternoon and asked the AI system to help me build a prototype that would analyze Google Maps or other public spatial data for famous canyons and convert it to audio. In early 2026, the frontier system generated a single HTML file with the contours of my idea and a dozen placeholders that sat where all the hard parts needed to be implemented. It was a good conceptual mockup, but my generative music system didn’t play music worth listening to, so I set it aside.

I reopened the same project six months later. This time I’m using Claude Code + Fable 5.1 + Max plan.
