Why “OpenBSD Mastery: Filesystems” Is Not in Amazon’s Kindle Store
You can get OpenBSD Mastery: Filesystems for Kindle direct from me at Tilted Windmill Press or at Gumroad . You can get a Kindle-friendly ebook from any number of other retailers, but while they’re all supposed to be DRM-free I can’t advise on prying the file out of another vendor’s ecosystem. The one place you cannot…

Raspberry Pi security alarm – the basics
In November last year — I started building a DIY security alarm system, using a Raspberry Pi as the controller. My plan was to make a self-sustained system, using proper alarm hardware — like PIR sensors and sirens. Integration with Home Assistant would be an add-on, not a requirement. I wanted the system to be as…

An M1 for Curl
A generous member of the wider curl community stepped up and donated an unused Mac mini m1 model to me to be used for curl development. Today it arrived at my home. An 8C CPU/16GB/1TB/8C GPU/1GbE model as per the sticker on the box. The m1 mac mini, still wrapped in plastic. Apple is not … Continue reading An m1 for…

SQL + M4 = Composable SQL
I often work with clients who have large “data lakes” or big star schema style enterprise databases with fact and dimension tables as far as the eye can see. Invariably said clients end up with a substantial SQL codebase composed of hundreds of independent queries with lots of overlap between them. I want to be able…

Saying “sup” with `net send`
When I was in junior high, my friends and I discovered that a Command Prompt command called net send was enabled on our school network. AIM and similar services were blocked, but if we wanted to send messages to each other we could open up the Command Prompt and type something like: net send lab2126-24 test and get an…

Extending Python with Rust
Sometimes a pure Python script can't just deliver the performance we need. When that's the case we have to resort to writing our logic in a "fast" compiled language like C or Rust and expose the function with through a Python module. This way we get the best of both worlds. Today I focus on how to use Rust for writing…

All I want for Christmas is these seven TypeScript improvements
It's Christmastime and I've been happily working through this year's Advent of Code in Deno (look forward to a blog post in the new year). What with all the presents, it's a good time to think about what we'd most like to see from TypeScript in the new year. Here are my top seven feature requests for 2023. Yes, that's…

Win16 Retro Development
Several months ago I had a go at producing a high resolution 256-color driver for Windows 3.1. The effort was successful but is not yet complete. Along the way I re-learned many things I had forgotten, and learned several new ones. This blog entry is based on notes I made during development.
