Field notes from 35+ years in the trenches. Mostly C# / .NET / Avalonia,
some Rust, rants about OOP, retro emulation, and whatever weird thing has me up at 2am.

Thermalith: an open-source desktop label designer for NIIMBOT printers
I went quiet on the blog for a month because I was building this. Thermalith is an open-source desktop label designer and driver for NIIMBOT thermal printers: local-first, no account, no cloud, prints over USB or Bluetooth. Cross-platform on .NET 10 and Avalonia, with the reverse-engineered printer protocol pulled out into its own reusable GPL library.

Built in private, released in public: self-hosted GitLab to GitHub
The workshop is a self-hosted GitLab I own and run. The shop window is GitHub. Development happens in private with no metered CI bill and full control of the runners; when a release is ready, one GitLab CI job mirrors the source to GitHub and cuts a release with the built binaries. Here's the actual pipeline that does it, gotchas included.

A coffee button, and a home for the projects
Two reader-facing additions to the site this week. There is now a Donate page with Ko-fi and Interac e-Transfer, and a Projects section where each thing I build gets a real writeup instead of a line on a GitHub profile. Neither is clever. Both are things I kept meaning to do and finally did.

I added an apple-touch-icon by reading my own access logs
Stood up GoAccess on the production logs this morning. Noticed iOS clients 404'ing on /apple-touch-icon.png within minutes. Resized the admin avatar with PowerShell and System.Drawing, dropped the result at wwwroot/apple-touch-icon.png, deployed. Thirty minutes from 'huh, that's a lot of 404s' to live. The story is the loop, not the icon.

I'm writing a history of Visual Basic, Chapter 1 is up
Starting a long-form history of Visual Basic on EvilGeniusLabs.ca. Chapter 1 covers the BASIC dynasty Microsoft had been running since 1975, the California developer Microsoft bought to put a face on it, and the launch pitch Bill Gates seeded in BYTE Magazine eighteen months before VB shipped. Six articles, focused on the parts of the story that don't get covered.

Mea culpa, I shipped a draft-book feature that hid every chapter inside it
M12 said draft books are public works-in-progress. I updated the book-level visibility filter and called it done. The article-level filter, which lived in seven other queries, was a separate code path. Anonymous visitors saw the book, saw the chapters, and every chapter rendered 'no published articles'. Here's what I missed and the fix.
