My roborock S5 (vacuum robot) can be hacked and I can access it via ssh. Not alot of ram, armv7 CPU, but it can run docker. One time I managed to play internet radio over terminal, so it plays music and vacuums my home. Nice 😎
We had a fancy coffee machine at an old job that ran Linux. If I remember correctly it was a top of line cafection or zulay machine. One of the ones with a touch screen. Just booted off an SD card as well iirc so probably would have been pretty easy to hack on.
I still find it weird that managed switches run Linux as I generally would think that at those data rates they’d need something closer to the metal but with the magic of HW offloading that’s been a thing in enterprise for a while and OpenWRT even supports some consumer grade ones now.

EDIT: Totally forgot about these 2 ham radios. You can run and access Linux on both of these. One is by design as its running on a Pi, the other via mod by R1CBU booting the OS from an SD card.

Software defined radios are kinda a stretch. The radio hardware isn’t running Linux. There’s a receiver that converts the signal to digital and then a Linux computer processes the signal. Basically the exact same thing as my computer having a radio receiver plugged in to it but packaged up as a standalone thing. If that counts, my keyboard runs Linux.

They might be running userspace networking

Also hard drives. No, not like that.
It doesn’t have as much to do with where the network stack is running, but that they’re leveraging hardware offloading. Their CPUs generally aren’t powerfull enough to switch packets at gigabit speeds let alone on many interfaces at gigabit or multi-gig speeds. Its by leveraging ASICs and maybe even some using FPGAs for hardware offload that they can switch packets at line rate. I understand how they do it, I still just find it kind of weird and cool.
I didn’t list HDDs as someone else had mentioned that already. I was just listing a few devices that weren’t mentioned in other comments yet.
Both really, you can’t fully offload to hardware if your kernel still requires an interrupt to pass the payload. That hardware most likely has userspace drivers.
Oh yeah, didn’t even think about that. Isn’t using userspace network pretty common these days anyway?
Idk, needs more e-waste :(
Tell that to Samsung!
A PS4 can be jailbroken to run Linux. You can then install Steam and Halo and have Halo on Linux on PS4
A hard disk. Not boot from a hard disk, but the hard disk controller is actually made to run Linux: http://spritesmods.com/?art=hddhack&page=1
The leapfrog leappad used to run linux. People were able to hack them in order to run full on operating systems, by rooting their children’s learning toy
My iMac G3 is running Debian 6!
iMac G3
wow, an operating system on a computer, sounds so improbable :P
The computer is older than me :)
Linux can be run on an Nintendo 64. Mainline Kernel support has been added in v5.12
Read an article some years back about someone installing Linux on a hard drive.
Not on a computer with a hard drive. On the embedded ARM core inside the hard drive. One of them anyways, I think this particular hard drive had three CPUs inside it actually.
On a hard drive. No, not a motherboard connected to a hard drive, a hard drive by itself. Sprite is brilliant.

thermostats not really… Smart fridges most likely yes.
Some of the smart thermostats almost certainly do. Also this one 100% does. https://hestiapi.com/
Yea sure those DIY projects will use Linux for sure.
Actually was looking into this some more, and came across this article.

Syringe drivers exist that are on-line devices. I half expect the first IoT murder to be by someone hacking a syringe driver filled with something vital (say insulin) that’s plugged into the victim’s IV.
I don’t know if such devices are capable of being jailbroken and installed with Linux, but why not?
Good work, 47. Now get to an exit.
