Back in 2021, I wired up data from Buienalarm and Buienradar through Node-RED and a big pile of Jinja2 templates to get a rain forecast graph on my Apple Watch: eight Unicode block characters showing the next two hours in 15-minute chunks, glanceable without unlocking the phone. It worked, and I used it every day […] The post Buienwatch, a custom Home Assistant integration for Buienradar and Buienalarm graphs on your Apple Watch appeared first on Style over Substance.

I deleted my favorite feature, and the image got better: Direct Binary Search (DBS) in OpenDithering

When I created OpenDithering back in June, the feature I was proudest of was the Auto-tune button. It did the slider work for me: it compared the dithered result to the original image, nudged the settings, and repeated until the image stopped improving. Over the summer it grew into a three-step process (Auto Expose, Color-tune, […] The post I deleted my favorite feature, and the image got better: Direct Binary Search (DBS) in OpenDithering appeared first on Style over Substance.

Dithering is obsolete (except when it isn’t); creating OpenDithering

Dithering is one of those techniques that feels like it belongs in a museum. It peaked in the ’90s, the era of 256-color palettes and early computer graphics, when you needed to trick the eye into seeing colors that your hardware couldn’t actually produce. Now, even our phones have OLED displays that do HDR, and […] The post Dithering is obsolete (except when it isn’t); creating OpenDithering appeared first on Style over Substance.

Black and white epaper photo frame based on Seeed Studio reTerminal E1003 using ESPHome and Home Assistant

Last year I wrote about how I had written an ESPHome configuration for the Seeed Studio reTerminal E1002 device to work as a small, color, digital art frame. This year, I wrote about how I had been using Claude Code to help me write Home Assistant code for myself. Those efforts have now combined in […] The post Black and white epaper photo frame based on Seeed Studio reTerminal E1003 using ESPHome and Home Assistant appeared first on Style over Substance.

Using Claude Code to write Home Assistant integrations

For the past few months, I’ve been dabbling with Claude Code. Not in a “no one needs developers anymore, anyone can build apps now” kind of way. More in a “I have a basic understanding of this, but not enough to turn it into code I can actually use” kind of way.

The Sting

The Sting belongs in the pantheon of films I'm deeply embarrassed to have not watched earlier. Not just because it's a great film — and it is — but because it is so incredibly my shit that I feel retroactively spurned for not having watched it sooner.

It's a Gas!

If everything worked as well as the product called Evapo-Rust, the world would be a much better place. That’s just one of the many lessons learned during my recent — successful! — project to transform my old, nonfunctioning gasoline-powered generator into something much better.

You Won’t Hear About These, Even In Myths (Atlassian Jira, Confluence (and more) Pre-Auth Arbitrary File Read CVE-2026-21589)

Welcome back to yet another episode of "security was taken seriously". Being who we are (and constantly being exposed to what we see…), we recognize we have been doomed to eternal damnation as we keep on watching security best practices crumble behind “secure by design”
