The open source operating system that runs the world.
Linux containers, Kubernetes, artificial intelligence, blockchain and too many other technical breakthroughs to list all share a common component - Linux, the same workhorse that has driven mission-critical, production systems for nearly two decades. Today, we’re offering a vision of a Linux foundation to power the…
As a rule, "sophisticated" progrmming is pretty boring - optimizing the unnecessary to speed up the uninteresting. Here, however, is an incredibly sophisticated package intended for fun and games. The more you know about software, the more astounded you will become as you read this.
