I love Opensource: my favourite list of opensource alternative

In 2014, when I switched to Linux I spent hours, days and month looking for free and open source alternatives to the commercial ones, by watching video, reading articles, story and even comments, it was a hard time but it made me a more positive and happy Linux user, now after five years i want to share with you my favorite list of open source alternatives including distros, tools, software… as a result of my humble Linux experience. Have a pleasant reading.
