 Hello, I'm Opensource.com Community Moderator V.M. Rasour and I'm bringing you this week's top five. This week we come to you from beautiful Melbourne, Australia, home of Paikan AU. This weekend Paikan AU is hosting hundreds of Paikan aficionados and programmers for dozens and dozens of excellent sessions. Several of them have agreed to help out with the top five this week. So grab a sausage roll, black, white, watch out for drop bears and enjoy as Paikan AU attendees share with you the top five most popular articles at Opensource.com this week. Number five this week comes to us from Nate Levesque who brings us an overview of the current net neutrality debate including the impact that losing net neutrality could have on free and open source software. This week's fourth most popular article is A Quick Guide to Types and Functional Programming by Kiko Fernandez-Rez. Kiko introduces the functional concepts of union, tag unions and algebraic datum types and when you use each type in your code. Coming in at number three it's Opensource.com Community Moderator Jono Bacon. He has the list of seven mistakes your open source project may be making right now. Jono shares how each of these mistakes can affect your project and what you can do to avoid or fix them. Opensource.com Community Moderator Don Watkins article five ways to use a Raspberry Pi in the classroom is the second most popular article of the week. Don not only provides tips for integrating Raspberry Pi in a classroom environment he also shares a lot of links with instructions for how to get started.
