History of National FreeBSD Day

For those who are still wondering what FreeBSD is, let’s break it up for you. FreeBSD is a free and open-source Unix-like operating system developed by the University of California at Berkley in 1993. It was a ground-breaking invention in open-source technology because FreeBSD can be modified and redesigned to meet the needs of the user, free of charge within the guidelines of the license.

Since then FreeBSD has reached great heights and has been hailed by many as the most popular and reliable free and open-source BSD-based operating system invented. Regardless of whether a person is familiar with FreeBSD or not, whether they knew it or not, they probably already use the plethora of services and products that use code derived from it. It is now being used on the servers of top tech companies including Netflix for streaming your favorite movies, WhatApp for communicating with your loved ones in any corner of the world in an instant, and is also used in the Sony PlayStation 4 gaming console for its awesome features. In fact, can you believe that Apple’s macOS is based on BSD? Yes! This is why it’s probably a good idea to observe National FreeBSD Day every year.

FreeBSD Foundation founded National FreeBSD Day with the main aim to recognize its pioneering and continuing impact on technology and honor its legacy. So, if you’re a tech and education enthusiast and love FreeBSD, you are probably using it on your computers now. This calls for a celebration!
