Linux doesn’t only run on home computers. You will also find it in some much more exciting pieces of kit. It’s particularly common where the proprietary nature of Windows and macOS is not suitable. Let’s take a closer look at some of the most unusual ways people and companies around the world have used Linux.

1. Large Hadron Collider

Linux

The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It’s a 17-mile long circular tube that’s buried 175 meters below the French-Swiss border near Geneva.

It’s common knowledge that the facility has been resounding success from a scientific perspective. But the LHC is also a computing miracle.

In its first 12 months of operation, the LHC produced more than 50 petabytes of data. The team needed 170 computing centers across 42 countries to analyze it all in a timely manner. It is the largest distributed computing grid in the world.

Linux runs both the LHC itself and the associated data centers. To be more precise, the LHC uses a modified version of Scientific Linux.

2. Air Traffic Control in the United States

In 2006, the Federal Aviation Administration (FAA) migrated its entire computing operation over to Linux, including all the machines that track planes while they’re on radar.

The organization moved from a proprietary form of Unix to Red Hat Enterprise Linux.

The decision was part of a wider FAA decision to move away from proprietary software and instead focus on apps using Java, web services, open-source software, and Oracle products.

Fast-forward to today, and Linux is responsible for the safety of the 8,000 planes that are in the sky above the US at any given time.

3. Putting Milk on Your Cornflakes

Linux

DeLaval isn’t a name that many people will recognize, but it’s one of the largest farm equipment manufacturers in the world. The company enjoys annual sales in excess of $1 billion.

One of the company’s most popular products is its automatic cow milking machine. It lets farmers extract milk from their herd using a wireless remote control.

And guess what? Yes, it runs on Linux. The operating system is directly responsible extracting the milk you put on your cornflakes every morning!

4. Self-Driving Cars

Google’s autonomous car computers run Linux, while early prototypes from both GM and Volkswagen also chose the operating system. Indeed, Google’s first successful foray into the market—a self-driving Toyota Prius—ran on Ubuntu.

Since those early days, we’ve seen the creation of Automotive Grade Linux (AGL). It’s a collaboration between car manufacturers, suppliers, and technology companies in a bid to create a de facto industry standard for automotive applications.

As of this writing, you can find AGL in models from Toyota, Ford, Mazda, Honda, Subaru, and Suzuki.

5. Tsunami Sensors

Ever since the 2004 Indian Ocean earthquake and tsunami killed 280,000 people in South-East Asia, tsunami prediction has become a vital part of public safety for people living in earthquake-prone low-lying areas. (If you’re at risk, technology can help you survive natural disasters 10 Must-Have Gadgets to Protect You Against Natural Disasters 10 Must-Have Gadgets to Protect You Against Natural Disasters Hurricanes, tornadoes, earthquakes, blizzards, floods, wildfires, droughts. The earth can be cruel. If you underestimate the strength of natural disasters, you may find your life forever upended in the blink of an eye. Read More ).

One of the leading manufacturers of tsunami sensors is American company Teledyne Technologies.

The company’s sensors—which run on Linux—come complete with their own modem and use acoustics to send the data to each other underwater.

Bottom line? Linux is changing the world and saving lives.

6. North Korea’s State-Run Operating System

Does North Korea have nuclear weapons? No one knows. But we do know that the country has an impressive state-wide computer operating system that’s based on Linux.

It’s currently up to version 3.0, but 2008’s version 1.0 remains the most popular. An installation CD costs the equivalent of about 25 cents.

The operating system includes Naenara web browser (which is a Firefox fork). OS version 1.0 and 2.0 took their visual inspiration from Windows XP. Version 3.0 looks more akin to macOS.

7. Nuclear Submarines

In 2004, Lockheed Martin delivered a new nuclear submarine to the United States government. The vessel’s sonar ran on a Red Hat Linux-based operating system combined with Apple Xserve servers. It was a first for submarine sonar at the time.

Lockheed Martin chose Linux for two important reasons.

Firstly, it allowed the sonar to run in a low heat, low power consumption mode, both of which are essential features on a submarine.

Secondly, the end of the reliance on embedded systems allowed the crew to adapt to various formats of data and encryption while at sea.

8. San Francisco’s Traffic Control System

In 2011, the city of San Francisco decided it was time to update their traffic control systems. Given it’s the 30th most congested city in the world, it’s vital that its traffic management systems are reliable.

These offline GPS apps for Android will help you navigate. Read More just won’t cut it.

The city authorities decided that Linux would power the system. It was built around a Freescale PowerQUICC II Pro processor and was designed to meet the national Advanced Transportation Controller (ATC) standards.

Sounds great, but San Francisco now faces 25 percent more congestion than it did when the system was implemented. Still, we’ll put that down to the west coast drivers rather than a failing of the operating system.

Linux Controls the World

Clearly, Linux is everywhere. In this article, we not even touched on “fun” everyday uses such as smart TVs, Roku sticks, Nest thermostats, Kindle e-readers, and all the rest.

And even though we’ve only listed eight unusual uses, the wide variety of the examples will hopefully give you an appreciation for how widespread the operating system is.

    Nice post! Would have been great to include how Linux is integrating into the data center; first with servers, then with apps, and now through the actual network operating system.

    You neglected to mention the ISS, which used Linux to replace Microsoft Windows XP.

    I'd just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.

      Pedant.

      Linux has become a generic name just like kleenex, xerox and coke.

      This is a long-standing thread on many sites, and it has never been clear whether Linux = GNU/Linux.

      GNU/Linux doesn't exactly roll nicely off the tongue, does it? "Linux" has become the colloquialism for GNU/Linux. Besides, some of these examples aren't limited to GNU implementations of the Linux kernel, so calling it GNU/Linux would not be appropriate in this case.

      Nice copy and paste of R.Stallman's ideology instead of being original in your opinion. Linux is Gnu/Linux and the terms are so oft interchangeable that Linux is used 100% of the time: it's easier to type and speak. You can call it whatever the heck you want to, but at the end of the day, everyone is free to do as they wish, even if that means contradicting R. Stallman's ideology.

    Good to know.

    Thank God Windows isn't running the Hadron Collider. We'd all be dead.

    What an ignorant article. Aside from the nonsensical comment about North Korea's nuclear weapons, your opening sentence, "Linux doesn't only run on home computers," suggests that you don't have the slightest idea what Linux is used for. You've made no mention of it running servers... Linux is, at its heart, a server OS. It's used on more servers than any other OS, including but not limited to most web servers worldwide - most likely the server serving this website is running on Linux. Please, don't write articles if you are completely and totally uninformed on the subject.

      I'll ignore your unnecessary insults, and instead suggest:

      1) Please re-read the intro for an insight into what to expect from the piece:

      "... the most unusual ways people and companies around the world have used Linux."

      2) Read this, also written by me:

    Ummm, we know with absolute certainty that North Korea has nuclear weapons because it has detonated them many times. They've had the A-bomb for years and are close to a reliable H-bomb, and have already tested several prototypes with varying levels of success.
