GoPro is struggling financially with a 26% revenue drop in the first quarter of 2026 and may not survive the year without a new owner or fresh cash. Founder Nicholas Woodman is propping up the company with a $20 million loan, but a buyer is being sought to take over the brand.

Setting up your spare Mac for Claude Code to control, a step-by-step guide

Here’s a full step-by-step guide on how to turn your spare Mac into an always-on machine Claude Code can fully control, with computer use enabled. You’ll be able to talk to it from your phone through the Claude app, or from your main Mac over SSH. I wanted to create a separate environment Claude Code can control on its own, so I can delegate tasks I don’t necessarily want to run on my own ...

Regressive JPEGs

https://maurycyz.com/projects/bad_jpeg/cats.jpg
The post explains how JPEG progressive scans can be used to progressively display low‑frequency data, and how the author exploits this by concatenating multiple scans (mostly DC‑only) to create a pseudo‑animation that works in browsers up to about 90 frames. Although this trick bypasses the usual 9‑scan limit and avoids ghosting, it has no real practical use because timing must rely on ...

Frozen 2 should be Rated R

https://interconnected.org/home/2026/07/17/frozen.png?v=1
I watched Ferris Bueller’s Day Off which was as great as I remember. It has an age rating of PG-13 in the US and 15 in the UK for bad language and some kissing. (There is also lying to parents but apparently that doesn’t count.) I have way less problem with some light cursing/petting than films that are ostensibly for kids like cartoons and superhero movies that treat mass existential threat ...

The Fermi Paradox, Percolation, and Inbreeding

https://reactormag.com/wp-content/uploads/2026/07/Kepler-K2-138-System-740x423.jpg
What do cheetahs and genetic bottlenecks have to do with interstellar colonization? Glad you asked... Well-timed synchronicity is a wonderful thing. There’s nothing quite like the intellectual zing one experiences when one scientific presentation casts an unexpected light on a seemingly unrelated theory or idea. I was the beneficiary of this phenomenon last week, when scarcely twenty-eight ...

The Computer at the Bottom of a Canal

https://negroniventurestudios.com/wp-content/uploads/2026/07/01-hero-canal-labelled-master-1024x574.png
The Rekursiv, a custom silicon chip designed in the 1980s, was right about many things, including memory safety, garbage collection, and persistence, but was ahead of its time and failed due to economics. Now, with the commodity curve dead and new technologies emerging, the Rekursiv's ideas are being rediscovered and implemented in modern silicon, making it a relevant case study for ...

Reviving a 15-year-old netbook with Arch Linux

https://parksb.github.io/images/b02b09c6-db90-4570-a7f0-aafa29bc3ae9.webp
I revived an ASUS Eee PC 1000HE, noting its weak Atom N280 CPU and 1 GB DDR2 RAM, and installed Arch Linux 32 to run a lightweight LXQt desktop, detailing partitioning, networking, and swap setup. After upgrading RAM to 2 GB, I still faced performance limits due to the aging HDD and CPU, but the machine now serves as a modest server or media device.
