Although the term “open source” didn’t arrive until the late 1990s, the principle has been around since programming really took off in the 50s and 60s. Early developers shared their code and protocol designs, a process that ballooned with the advent of the internet in 1969.
Open source software is now ubiquitous, both hiding in plain sight and acting as an unsung hero behind the scenes. The tools I’ll cover here are vital for vast swathes of our daily lives, even if they rarely get the credit they deserve.
Linux
It’s everywhere, from game consoles to mobile phones
We’ve all heard of this one, but it’s impossible to overstate the importance of Linux in our current lives. Still relatively new—it only really started being used in the wild around the mid 1990s—this operating system is best known to the wider public in its form as Android, the dominant smartphone OS.
Linux is such a flexible system that it’s difficult to even pin down: a kernel to some, a windowing environment to others, and embedded software to many who will never even realize it. It’s now so pervasive that a typical internet request will likely involve several different machines all running Linux, from your desktop through any number of proxies, and onto the final web server.
Git
The software that powers much modern development
Releasing one world-changing bit of software would be enough for most of us, but not Linus Torvalds. Linux’s Finnish creator is now almost as well-known for his follow-up, the version control system, Git.
This isn’t a sexy tool—even aside from its slightly off-putting name—but it’s fundamental to how much software is now produced, especially other open-source code. Git enables diverse teams to collaborate, end-users to contribute to the products they…
