From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux on non-PCs/Laptops (lemmy.world)

Aside from Linux running on NASA hardware, phones and consoles. Does it run on ATM machines, PDAs and point of sale monitors?

I ask this because I've seen Windows being used in airport terminals and really old versions being used for cash machines as well. The crowdstrike problem made this more prevalent by seeing "non end user computers" using the OS.

Does Linux fill this niche as well do you know? I don't recall hearing any big name embedded distro used for those sorts of machines. Maybe Alpine Linux or NetBSD?

Thank you in advance for your input!

There are tons of computers running Linux besides PCs. By far the biggest part are servers and supercomputers. Microsoft even has their own distribution for their server business. Then there are all the Android phones and devices. Android is Linux. In Germany I've also often seen Linux used for kiosks at government agencies.

Linux is used in TVs and set top boxes. Everything that says Tizen or WebOS is powered by Linux. I've also seen it used as in-flight entertainment systems. And Lunduke had an example of Linux running on a machine controlling how cows are milked, if I recall correctly.

For most systems you won't actually know what OS is used until you see a hardware error screen. Although Microsoft has made it a little easier with mandatory updates.

I am not positive but if it still true originally webos was not linux. It started off as a very ahead of its time cell phone os made by Palm Inc. After they failed to gain traction it was sold to LG or made open source then sold or bought. LG uses it in their TVs but if I recall the base os is not Linux but some form of palmos assuming it has not been moved to Linux.

[–] bjoern_tantau@swg-empire.de 2 points 3 months ago* (last edited 3 months ago)

Nah, WebOS was already Linux when Palm used it on their phones. I had one of them. I preferred the N900 and it could even run games made for WebOS.

The Deutsche Bahn uses Linux for the displays in their trains, that show you the next stops, at least. Saw the systemd startup thingy on one of those displays once when the train restarted while I was in it.

[–] superkret@feddit.org 21 points 3 months ago (1 children)

my old GPS device runs on Linux. My PC also runs on Linux. To transfer updated maps from the PC to the GPS you needed a proprietary software that only ran on Windows. God, that pissed me off.

[–] cm0002@lemmy.world 8 points 3 months ago (1 children)

Lol kinda related, but Uconnect sent me an email a few months ago about the GPS maps in my car (11 years old at this point) being way out of date...they wanted $300 (or something like that) for a flash drive with the map update.

Lmao, like it wasn't 2024 and Google Maps on my phone does a far better job than their proprietary crap they want 300$/update for

[–] toynbee@lemmy.world 1 points 3 months ago

My 2014 Ford Flex was the same way, except that they didn't contact me.

The car with which I replaced the Flex doesn't have onboard navigation, instead relying on Android Auto. I was pleased about this, thinking at least it wouldn't track where I was going ... Until I opened the app and saw it could still report its location independently. At that point it seems like there might as well at least be an option for onboard navigation.

[–] Presi300@lemmy.world 16 points 3 months ago

I want you to imagine an electronic device. Congratulations, you've imagined a device that runs some form of Linux...

[–] Karmmah@lemmy.world 16 points 3 months ago (1 children)

I saw the self checkout machines in my supermarket being restarted a few times and caught a glimpse of what was shown on the screen. Before they were upgrade some time ago they showed that CentOS was running and now I think that I saw Rocky Linux running on there. So yes, these are definitely out there and used widely.

Also I've see pictures of Raspberry Pis being used almost everywhere.

[–] lord_ryvan@ttrpg.network 8 points 3 months ago (2 children)

Holy cow what country is this? All the self-service check outs in our Dutch Albert Heijns and Lidls use Windows 10/11!

A good boba tea shop, Sencha Silk near Arnhem Centraal, their self checkout used unregistered Windows 10's and upgraded them to unregistered Windows 11's recently, judging by the watermark on the bottom-right. Based.

[–] Karmmah@lemmy.world 4 points 3 months ago

It's Aldi in Germany. Running Linux however does not prevent these machines from getting errors all the time so often times there are only 3/6 machines available since an employee has to reset the software manually.

[–] bubstance@lemmy.sdf.org 3 points 3 months ago* (last edited 3 months ago)

I can say that, at least in the Southwestern US, our local Kroger stores all use Linux of some variety at their self-checkouts. I've seen the same as above: mostly CentOS and Rocky.

[–] LavenderDay3544@lemmy.world 14 points 3 months ago

Linux is much more commonly used in embedded systems than Windows for obvious reasons.

[–] wildbus8979@sh.itjust.works 13 points 3 months ago (2 children)

A ton of digital signage (think fast food restaurant menus) run Linux as well.

Most home routers do as well.

[–] Fisch@discuss.tchncs.de 1 points 3 months ago (2 children)

Wouldn't a home router with Windows cost way more because of the licence?

[–] wildbus8979@sh.itjust.works 9 points 3 months ago (1 children)

Probably would also need like ten times the amount of ram and disk space. These things usually run on 64/128Mb of RAM and anywhere from 8 to 32Mb of flash.

[–] princessnorah@lemmy.blahaj.zone 1 points 3 months ago (2 children)

I think those numbers might be on the low side. Like, not by heaps though. My Asus RT-AC86U has 512MB of RAM and 256MB of flash. It's not exactly new either, I'd imagine an AX router would need more.

More, but not way more - they would be licensing window IoT, not a full blown OS, and they wouldn't be paying OTC retail rates for it.

[–] ReveredOxygen@sh.itjust.works 1 points 3 months ago (1 children)

Don't most routers run some form of BSD?

[–] wildbus8979@sh.itjust.works 1 points 3 months ago

Never heard of a commercial home router running a BSD derivative, but I'm sure it's possible. Almost all of them have a GPL li censée disclosure so....

[–] Telorand@reddthat.com 13 points 3 months ago (1 children)

Yes. My work uses Ubuntu for certain touchscreen PoS devices they sell to their customers. It runs their proprietary apps automatically, and the end user doesn't know or care that it's Linux underneath.

[–] lord_ryvan@ttrpg.network 1 points 3 months ago (2 children)

What are PoS devices?

[–] ccdfa@lemm.ee 11 points 3 months ago

Pieces of shit devices

(Point of Sale, jokes aside. But they often are POS as well.)

[–] slickJujitsu@lemmy.today 3 points 3 months ago (1 children)

Point of sale. The devices you stick your card into to pay.

[–] Telorand@reddthat.com 4 points 3 months ago* (last edited 3 months ago)

Yep, though in this case, it's more like a cash register/scanner than a card reader.

[–] popekingjoe@lemmy.world 10 points 3 months ago (2 children)

My company has a robot scrubber that runs a custom Linux distribution.

[–] reddeadhead@awful.systems 6 points 3 months ago (1 children)

We have a coffee machine that runs on linux.

[–] popekingjoe@lemmy.world 4 points 3 months ago

That is really cool.

[–] toynbee@lemmy.world 4 points 3 months ago (1 children)

Is that a machine that scrubs robots or a robot that scrubs?

[–] popekingjoe@lemmy.world 2 points 3 months ago* (last edited 3 months ago) (1 children)

It's a floor scrubbing robot. It uses LIDAR, a 3D depth camera, and a couple 2D side cameras to map and navigate its routes. It was cool for about six months and now we just default to manual driving because it's slow and gets stuck very often.

[–] yuri@pawb.social 3 points 3 months ago (1 children)

scrubbing floors with an RC car still sounds pretty cool

[–] popekingjoe@lemmy.world 2 points 3 months ago

Man I wish it was that cool. Controlling it remotely would be primo. Unfortunately, it's not, and I work in a building that's 183,000sqft. If I have it running automatically on the other side of the building and it gets stuck, I'm suddenly burning time to run over and unstuck it.

[–] JustARegularNerd@aussie.zone 8 points 3 months ago

The digital sign the local university has is powered by a Raspberry Pi - I caught it rebooting while driving past

[–] CalcProgrammer1@lemmy.ml 8 points 3 months ago (1 children)

Linux on phones and tablets is a thing. Typing from my Xiaomi Pad 5 Pro running postmarketOS and LibreWolf.

[–] data1701d@startrek.website 3 points 3 months ago

One, although it’s rare to have phones that support it, I do dream of owning a Linux phone one day.

Two, I have no idea why I was surprised to run across the OpenRGB guy on Lemmy.

[–] Scrath@lemmy.dbzer0.com 6 points 3 months ago

Not sure if that's the kind of device you are asking about but kobo e-readers run Linux. It's allowed me to sideload my books over SFTP instead of always having to plug in a USB cable

[–] LunarLoony@lemmy.sdf.org 4 points 3 months ago

Examples I've seen in the wild:

  • Argos POS terminals using CentOS
  • ATM using OS/2 Warp
  • Co-op tills running (I think) Windows Embedded POSReady
  • TVs using Yodeck (ultimately Raspbian, I guess)
  • Occasionally, ad terminal things using Raspbian
[–] Magister@lemmy.world 4 points 3 months ago

Pretty sure ATM runs on super old stuff like OS/2 or Windows XP or Windows CE ?

[–] Mispasted@lemmy.ml 3 points 3 months ago

There's a jack-in-the-box here that runs linux on their drive-through screen. I only know because it's had a "vmlinuz not found" error for a few weeks now xD

[–] LeFantome@programming.dev 3 points 3 months ago

I have had seen a few in-flight entertainment systems crash and reveal that they run Linux. The crashes have been due to network issues as far as I could tell ( so no strike against Linux for that ).

Similar story for display panels at fast food places and hotels. Online, I have seen at least one Linux billboard.

My company uses Linux extensively for video monitoring systems in vehicles like busses, fire trucks, ambulances, and police cars.

[–] GustavoM@lemmy.world 3 points 3 months ago

I've got two Orange pi zero 3's (one acting as my "home lab" and the other one as my... lab rat.) which aren't ATM machines or PDA's, but... they are more like "very confused potatoes who think they are pcs" and everything "just werks" as intended.

[–] TwoBeeSan@lemmy.world 2 points 3 months ago

Most digital signage I see is a Chromebox running a specific kiosk software.

android on occasion as well

[–] vort3@lemmy.ml 2 points 3 months ago

I saw Linux used on Boeing passenger service systems.

[–] Ep1cFac3pa1m@lemmy.world 2 points 3 months ago

I worked in retail until 2016, and a few years before I left they switched all the PoS registers to Linux.

[–] Ephera@lemmy.ml 2 points 3 months ago

A local shop has these self-checkout registers on which I saw they're running CentOS.

[–] bloodfart@lemmy.ml 2 points 3 months ago

There’s not a distro because the companies that sell those pieces of equipment have their own software packages that sit on top of some distribution that they sell as a whole doohicky they call an appliance.

The distributions that are most often used are those with either direct support from a company the appliance manufacturer can work with or some distro that’s feature compatible with one of those kinds.

I recently saw Domino's Pizza uses this touch device to take customer order that uses some very old version of Ubuntu (with unity DE)

[–] data1701d@startrek.website 1 points 3 months ago (2 children)

At first, I was trying to think of some alternate explanation like they’d just bothered to install Unity on a newer version (which I instantly had to self-reject that notion as bonkers). My guess is that that’s the version the stack was developed for and initially rolled out at guinea pig restaurants before a wider introduction (I don’t know when these were introduced, as I rarely do Dominoes.).

Not really much of a problem with it, as if it’s 16.04, it’s still getting extended updates to 2028 and will probably have a paid extra two years offered that Dominoes is willing to pay. If it’s 14.04, then it’s already on paid extended support until 2024.

Not that I’d touch straight Ubuntu with a 39 and a half-foot pole anytime soon, though some derivatives manage to make good out of it, the best being in my opinion PopOS.

Some automotive infotainment systems run on Linux.

[–] limelight79@lemm.ee 2 points 3 months ago* (last edited 3 months ago)

I came across a bowling arcade game that ran Linux. Still kind of wishing I'd bought it.

Pretty sure it's this one.
