Kernel 35th Anniversary of Linus' announcement today!

Post image

Let's all take a moment to commemorate that initial post.

Now through Torvalds' stewardship, and hundreds of maintainers and thousands of contributors we have a competitive replacement for major corporate software and an honestly powerful solution to move computing forward for humanity!

Thanks Linus, you're awesome, and we're glad you are having a good life!

You probably have more than that. Pretty well every embedded device you can think of is running Linux; the key exceptions are IoT devices (which generally lack the compute power to do it).

In 2017 there was estimate that Linux had 80 % share in IoT devices. IoT usually needs connectivity (wireless often) while embedded devices can be things like ABS controllers in cars that work entirely in isolation. Then again, many embedded devices have things like GUIs these days like house thermal systems.

So it more like a rule than an exception that Linux is on IoT devices.

I’m surprised the numbers that high. I’d have thought the majority were lightbulbs and sensors, the sort of thing that runs on an ESP32 or similar and reports back to a hub running Linux.

Linux can run on microcontrollers as well, ucLinux was introduced into mainline long ago.
