In the 90’s, an amazing thing happened – Linux was born. This small project has had a profound impact on the world of technology. Not only did it create a Unix clone, it advanced the open source movement by leaps and bounds. During the decade after the creation of Linux, companies, like Microsoft, would argue against the idea of open source and attack Linux. But then, in the early 2000’s, things started to change for the Linux movement from an unlikely source – Apple. The new Mac OS X would use BSD (an operating system very similar to Linux) as the core of the operating system. The Linux world was very excited about this! The change meant that Unix/Linux hackers had support for Unix on a commercial operating system. Now, it seems that developers across the globe are using Macs for development. Why? Because services like Google Cloud and AWS, as well as Docker, use Linux. Mac users can develop cloud applications on their machine to be deployed to Linux servers and have similar environments on both. Where does Windows come into the picture? Microsoft has fought against these technologies, and has even come up with their own competing cloud service – Azure. But, as more and more developers jump ship to Linux or Mac, Windows needs to move. And over the last several years they have. Microsoft’s .NET Core is not only open source, but it also runs cross-platform – an idea that seems almost blasphemous to the Microsoft of a decade ago. And, as of last fall, Windows 10 includes the option to install Bash support on Windows. Indeed, it would appear that Microsoft has seen the writing on the wall and is working to change the direction of their company to be more friendly to the Unix world that has secretly been in control of computing since the dawn of technology. But is it too little too late? Can Microsoft lure developers back with a Bash shell? Time will tell. But, as for this Unix user, I’m glad to see the change.
