So it's no secret that some parts of the army in the USA and my country (UK) sometimes use legacy software like DOS for niche roles as they're robust including older versions of Windows.

But.. where does Linux fit in this? It's a kernel OS that's used in top of the line supercomputers, workstations, medical equipment and weather stations.

I imagine some aspects of this would be military secrets but how do they use it? I know that Linux was used for certain space projects with NASA but I'm talking about army applications.

TLDR : Does the penguin OS power shooty shooty machines and tanks

Didn't they at one point use a bank of PS3s when they still allowed for Linux boot options?

[-] [email protected] 4 points 1 day ago

I'm not sure about the military, but yes a number of researchers used PS3s for cheap computing power.

We used it as OS for the tank and airplane simulators, just because it made them cheaper compared to buying 500 Windows licenses

[-] [email protected] 11 points 2 days ago

I imagine they use it in much the same way as any enterprise. Running servers and workstations, mostly.

F16's run Kubenetes clusters.

Lots of individual bits of hardware on specialized devices will be running embedded operating systems. QNX is big in automotive for the same reasons it'd work on a rocket.

Also big in healthcare/medical products,btw.

Don’t look too deeply into this unless you’re comfortable discovering that the military and security state is a prolific contributor to many open source projects.

[-] [email protected] 39 points 3 days ago

SELinux was a product of the NSA. Maybe the best thing that agency has done.

[-] [email protected] 13 points 2 days ago

They also created ghidra! Probably second best

[-] [email protected] 4 points 1 day ago

Also PRISM. Maybe the third—wait, wrong side of the array—worst.

[-] [email protected] 9 points 2 days ago

I don't find that problematic as they are the ones how are likely to push for good security and reliability

I've heard that the DoD uses RHEL pretty extensively. RHEL in the US Military

That article says that the US military has the largest single install base for RHEL in the world, but that was about 15 years ago, I don't know if that's still true.

Apparently back then the US nuclear sub fleet and its sonar systems also ran on RHEL.

I suspect lots of military hardware runs some form of *Nix or BSD type system. Many embedded systems run some *Nix type OS, and a huge portion of the developed world's weaponry is smart, so it it full of low power embedded systems and custom SoCs.

Red Hat has long benefitted from being the primary enterprise Linux company based in the US (no, we don’t count Oracle). SUSE created US-based Rancher Government Solutions to get some of that business and it seems to have been getting a lot of interest, despite being early days. They did a good job of focusing on modern technologies and immutable systems.

[-] [email protected] 3 points 1 day ago

I'm super excited to see SLES more in the US government space with RGS. RedHat was my goto champion of FOSS in public sector but since they have gone less Libre/FOSS SUSE is last big commercial Linux company still going commuting to FOSS.

Most of that information is actually publicly available.

It depends on what side you are on. At the end of the day a tool is a tool

[-] [email protected] 5 points 2 days ago

I said such things too, but one day I ask myself, could I said it in front of people bombed by my tools ? Our tools are not neutral things, but produce and distribute by social relationship that we could fight. Sorry but we the rise of fascism and ecological disaster we could not afford to give up our power as producer to mass murderer

[-] [email protected] 1 points 1 day ago

Okay but at the end of the day it's not like you're Tony Stark making Jericho missiles.

Linux, encryption, the Internet, heck, computers, are so generalized as a technology that the burden of sin lies with whomever would pervert these tools against their fellow man.

[-] [email protected] 1 points 21 hours ago

I am not sure this is a wide spread behavior among the IT. Reading the "Debian Free Software Guidelines", we could have some doubts. My point is not that free software are good or bad, but that is not enough. If we want te be responsible as producers, we have to organize as such to stop production that killing us (with climat change or military for example) and promote the one that emancipate us. Free software are a way to achieve the last one, unions the fist one

Looks like that are switching over from a generic Linux into android

[-] [email protected] 15 points 2 days ago

Well I know my local army base (US) was looking for Linux sys admins, so I figure they have some servers on base.

[-] [email protected] 18 points 3 days ago

There are many reasons Microsoft software is only "good" (and I'm using that word loosely) in business and home settings. Can you imagine a rocket taking off and windows suddenly "rebooting to complete updates" (or whatever it is that it says along those lines)?

[-] [email protected] 8 points 2 days ago

Rockets probably use a dedicated OS that is safety validated. Getting something validated for critical operations is a massive endeavor.

[-] [email protected] 5 points 2 days ago* (last edited 2 days ago)

Correct, missiles use something like RTEMS, which is named because it was used for missiles (no really, it originally stood for Real Time Executive for Missile Systems) and the operating demands for missiles have to be real-time given their unique edge cases.

Disclaimer: I worked on RTEMS in College

[-] [email protected] 3 points 2 days ago

Not only is it hard to get certified for things like rockets but they usually use a realtime os like red hawk (a red hat fork).

I'm not so worried about stormtroopers using linux as much as guns, bombs, prisons, cops, torture, genocide, nukes, etc.

When I was in the army the S1 desk jockeys were using dedicated word processors with 8" floppies. Get off my lawn! :-)

Knowing what the army is like, that could have been in 2010 lol

Greek military uses Linux Mint, so yeah, it's used in some places. I believe the Indian one does too.

Linux distro NixOS is used by mil-tech company Anduril

[-] [email protected] 3 points 1 day ago

I've heard of Palantir, now Anduril... What's next, Saruman Ltd.? Uruk-Hai-corp? Poor Tolkien doesn't deserve his mythology being co-opted by war profiteers. :(

[-] [email protected] 2 points 1 day ago

BTW: Anduril is a startup from Luckey Palmer, the guy that built the Oculus VR headset in his garage. The later sold Oculus to Meta for 2 billion $. 3 ex Palantir guys started Anduril together with him.

[-] [email protected] 14 points 3 days ago

as they're robust

I would argue they are just what was used during development. After that, it never changes.

Why did they use it back then? Were there many alternatives? I do not know.

[-] [email protected] 8 points 3 days ago

I haven't done any work for the military but i can say that all the legacy systems I've worked on were because the specific software they need was written only for Windows 98 and the developer or company that created it is long gone. Keeping it going is a chore but switching to literally anything else is out of the question.

I could see for military applications that having the known quantity of a working piece of software that isn't changing anymore and can be swapped as an entire unit is an advantage, especially if it doesn't touch the internet in any capacity. But eventually you run out of people who know what to do if any changes need to be made.

[-] [email protected] 2 points 2 days ago

COBOL has entered the room... although i've heard Ada is more popular in military applications.

Linux is commonly used in the communications systems, like on invidual radio "stations". Propably used everywhere where high confidentiality and security is required.

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.
