GitHub's archives are backed up on microfilm in an Arctic mine.
Now, if the world ends, whatever survivors crawl out of the ashes will be able to access and use the software behind modern-day tech, perhaps on that weird post-apocalyptic operating system that some coders unveiled last month.
Since 2017, the Arctic World Archive, as it's called, has stored other digital records, including the Vatican archives, movies, and anything else deemed worth saving, according to a new Bloomberg feature.
And now, with Microsoft-owned GitHub's contribution, it also holds a hard copy of nearly all the open source software in the world, which can be read with nothing more than a magnifying lens.
The open source community is often dismissed as a fringe group of tech idealists, but much of the digital architecture with which we interact every day technically falls under the broad umbrella of publicly available open source code, Bloomberg reports. Think Facebook, Google, and Amazon — all of them rely on it.
So, while GitHub's data dump seems like — and probably partially is — a bit of a stunt, it could someday prove useful if a catastrophe wipes out the world's hard drives.
