iMac G3

wow, an operating system on a computer, sounds so improbable :P

ProgrammingSocks ,

The computer is older than me :)

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.

Some (probably most) ebook readers like the Kindle.

Many newer cars.

TI NSpire calculators.

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.

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.

Natanael ,

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.

GuyNoIRQ ,
@GuyNoIRQ@infosec.pub avatar

Oh yeah, didn’t even think about that. Isn’t using userspace network pretty common these days anyway?

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.

Don’t most thermostats and smart fridges run Linux?

melroy ,
@melroy@kbin.melroy.org avatar

thermostats not really.. Smart fridges most likely yes.

GuyNoIRQ ,
@GuyNoIRQ@infosec.pub avatar

Some of the smart thermostats almost certainly do. Also this one 100% does. hestiapi.com

Yea sure those DIY projects will use Linux for sure.

Actually was looking into this some more, and came across this article.

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 😎

LiveLM ,

You reminded me of a blog post by Tailscale where they jailbreak their robot vacuum and install a Open-source replacement for the cloud functionality

It’s not entirelly Linux, but there’s a port of FUZIX for the Raspberry Pi Pico microcontroller

gamey ,
@gamey@feddit.rocks avatar

I haven’t done it myself but I own a Pinephone (Linux phone) and that completely isolates the modem to prevent closed source code on the main OS and apparently that runns Linux, not sure if it counts because it’s technically Linux already but someone hosted his blog on that and wrote about it!

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?

Aceticon ,

At the level of microcontrollers there is an entire range with the necessary radio HW and enough computing power and memory to have WiFi and a TCP stack but not enough to fit Linux (stuff like the esp8266, which has only 80KB user data memory).

Those things essentially run just the one application on top of some manufacturer provider libraries (no OS, though if you really want to there’s an RT OS) and which can be something that gets commands via the network and activates some hardware via GPIO ports.

For example, smart LED lamps that can be controlled from a smartphone are made with this kind of HW.

Mind you, recently somebody managed to get Linux to run of a top range model of the most recent of these things (an ESP32-S3).

So I wouldn’t presume that a syringe driver can be made to run Linux, given that it’s functionality is simple enough to be implemented by a simple program that can fit in that kind of microcontroller.

I once saw someone running Doom on a pregnancy tester, so I’d imagine that it could run Linux as well.

flubba86 , (edited )

I saw that too, but it was a bit a bit misleading. The pregnancy tester for some reason had a pretty high resolution monochrome OLED display, so the guy used the tester’s display to show the Doom graphics. The actual device running Doom was a more powerful controller external to the tester stick.

vortexal ,
@vortexal@sopuli.xyz avatar

I’ll have to re-watch the video again if I can find it but I’m pretty sure that the video I saw was a different one because the one I remember watching had a pixelated screen screen with a low frame rate.

flubba86 ,

Well the one I’m thinking of, it had something like a 64x128 monochrome OLED screen, that fits the description of “surprisingly high resolution” for a pregnancy tester, but Doom would still appear as a “Pixelated screen” like you described. Its probably the same one we both saw. Either way, there is no microcontroller inside that device capable of running Doom, so an additional external microcontroller was attached to run the game itself.

vortexal ,
@vortexal@sopuli.xyz avatar

Well, I tried to look for the video I saw but couldn’t find it. All of the videos I could find have the game in monochrome with a high frame rate, while the video I remember watching looked similar to the GBA version but with a significantly worse resolution and frame rate.

vortexal ,
@vortexal@sopuli.xyz avatar

After looking through some other Doom on “insert device here” videos, I couldn’t find it but I found one where the gameplay looks similar (even though it’s a completely different device and the game is clearly modded). The video is called Doom 2 on optimus maximus.

PipedLinkBot ,

Here is an alternative Piped link(s): piped.video/watch?v=q7b9glYuAXw

Piped is a privacy-respecting open-source alternative frontend to YouTube.

I’m open-source, check me out at GitHub.

IsoKiero ,

It wasn’t even original display. Original display wasn’t “pixel based”, it just had couple of segments on a LCD which display pregnant/non pregnant texts and some other info. So it was (is) just a doom on a microcontroller+OLED in a pregnancy test case.

A PS4 can be jailbroken to run Linux. You can then install Steam and Halo and have Halo on Linux on PS4

ViciousTurducken ,

Back in the day some iPhones could run janky forms of Android/Linux. I don’t think it ever got to daily driver status but it was surprisingly feature complete.

We have a carbon evaporator that runs linux

superkret ,

Is a carbon evaporator the Bond villain gadget it sounds like, or something boring as usual?

rigglesbee ,

It’s how they got Han Solo out of the Carbonite.

lanigerous ,

It’s definitely not as exciting as it sounds. It applies a large current through some graphite rods which causes the carbon to evaporate & deposit on a sample sat underneath. It’s used to coat electrically insulating samples with a conductive layer of carbon for electron microscopy.

PraiseTheSoup ,

This is indistinguishable from wizardry to me.

lanigerous ,

It is wizardry right enough - electricity goes in, magic occurs,l and machine goes ping

On a hard drive. No, not a motherboard connected to a hard drive, a hard drive by itself. Sprite is brilliant.

Sorry to hijack, but does someone have a link to the talk? Article mentions it, but link no longer works.

A hard disk. Not boot from a hard disk, but the hard disk controller is actually made to run Linux: spritesmods.com/?art=hddhack&page=1

Rand0mA ,

I had an old iPod nano that was hacked with a light Linux distro. Could even run doom on it… It ran, but wasn’t practical to play it.

marquisalex ,

Rockbox, by any chance? I have fond memories of playing doom with that scroll wheel…

Rand0mA ,

Pretty sure it was just called iPod Linux.

Just looked… looks like rockbox is the successor. en.m.wikipedia.org/wiki/IPodLinux
