@jakub_neruda Might be, whatever. Memory safety bugs are these, where code creates a risk of access to memory that hadn't been originally specified. and C++ have a problem, as many language constructs don't have protection mechanisms against out-of-bounds, double free, etc.

There's other category of bugs to which is prone to (not ) like C and C++ which don't allow - implicit nullability. The nature of JVM doesn't turn them to security risk, but they cause a lot of crashes.

It's time :)

Hello, I'm Rafael. I currently work on development of tools and infrastructure for flight simulators, and tinker with synthesizers and microcontrollers in my spare time.

Here you can follow my personal projects' progress and other things I do in my spare time.

Feel free to ask me questions about etc.

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.
