As the @bsdcan lists of talks and tutorials have been posted, I can officially announce my presentation:

Don't Freeze in the Cloud: Reclaiming Home Control with NetBSD

In 2010, I was taking more flights than cups of coffee. After a two-week trip, I returned home to a nasty, albeit expected, surprise: an indoor temperature of 7.8°C (46 F). Possessing more time than money, I decided to solve the problem my own way. I built a custom Python-based control system, accessible only via VPN, to manage my heating.

In 2015, after moving houses, this system was demoted to a secondary role, replaced by a shiny, commercial "smart" thermostat. However, I continued to maintain and update my custom solution for fun.

Fast forward to October 2025: major cloud providers faced significant outages. My commercial thermostat became dumber than a mechanical switch. I was reduced to manual two-hour overrides, with no visibility into settings or usage. It was a wake-up call: keeping my home warm should not depend on someone else's server.

I dusted off my solution and adapted it to modern needs - powered, of course, by NetBSD, running on the very same hardware that served my previous home for years.

In this talk, I will share the journey, the technical challenges, and the architectural decisions behind the project. I will demonstrate how NetBSD’s stability and low footprint make it the ideal operating system for long-term, "set-and-forget" home automation, allowing us to reclaim control from the cloud.

This morning I was thinking about something: one of the reasons why every enthusiast should consider going to a BSDCon is simple.

I eat a lot and I still come back slimmer 😄

2024 - EuroBSDCon: ate twice as much as usual, came back from Dublin 1 kg lighter.
2025 - BSDCan: breakfasts that could cover a whole day’s calories, huge delicious meals... came back from Ottawa 0.5 kg lighter.
2025 - EuroBSDCon: double breakfast (sweet + savory), massive lunches, delicious dinners (including a huge pizza, as @outofcreativity, @angie and @mwl can confirm) and still came back 0.5 kg lighter.

Positive emotions burn calories.

So come to BSDCons: you’ll come back happy and slimmer!

Anyway, I've reduced my ambitions ever so slightly, and am now in the process of installing NetBSD (-CURRENT) on what is essentially a 386SX-class machine: 16-bit bus, 24-bit addressing, 16MB RAM, and nearly as unpleasantly slow as the 286 I had planned to use. It is however equipped with an IBM-branded 486SLC, which is from the Blue Lightning series. This one definitely has a full 486 instruction set. More hardware details will follow when I've completed the build (and installation).

Meanwhile, the obligatory screenshot from the installer. Note the ETA for simply unpacking base.tgz ..

Screenshot from installer. Shows base.txz being extracted, at a speed of 110 KB/s. ETA given is about 30 minutes, which turned out to be relatively accurate.

All of those things are absolutely wonderful and make many of todays software developers look ... spoiled? What I want, however - and what I love doing - is making this old hardware do stuff its makers never dreamt of, things that are as far removed from their time as possible. That's why I will, if #NetBSD permits, run bleeding edge BSD on a 286-on-486steroids, and why I run web+ftp+irc servers (yes, multitaskign) on one 286 and multiple BBS nodes on a 386 - like one used to do, of course.

I cannot state often enough how amazing it is that there's still software developed today that will work under such constraints.

Until #snac starts doing work of course. Then I just sit back and wait.
