 Hi, it's Jen from opensource.com bringing you the top five articles this week, October 24th. At number one this week, we have Head of Open Source of Facebook opens up. Remy DeCosmaker attended James Pierce's talk at the open source conference, OzCon in Portland this summer and shares with us a partial transcript of his session on the state of open source of Facebook. I heard James Pierce's talk yesterday at the All Things Open conference in Raleigh. If you haven't heard about it, it's a fantastic time, amazing speakers, check it out for next year. So James Pierce and his keynote talked about how Facebook has taken a serious look at their GitHub repository, how they cleaned it up, and got it to over 200 active healthy open source projects. An interesting fact that he shares with us too is a question he asked Facebook employees to get a grasp on the level of importance open source plays at Facebook. He asked them, were you aware of the open source software program at Facebook? Two-thirds of responding developers said yes, and half of them said that the open source program positively contributed to their decision to work for the company. At number four, we have Chief Architect of Cloudera on growth of Hadoop. Robin Mulwick interviews Doug Cutting of Cloudera, a business providing services to big data companies and users of Apache Hadoop. Prior to his talk at the All Things Open conference this week, Doug talks about where he thinks the future of Hadoop is going and what he likes about working in open source software. At number three, we have top three open source alternatives to Google Analytics. Scott Nesbitt writes, if you have a website or an online business collecting data on where your visitors or customers come from, where they land on the site and where they leave is vital. Why? Having that information can help you better target your products and services and beef up the pages that are turning people away. You may know that one of the best ways to gather that kind of information is through web analytics tools, and you may also be most familiar with Google Analytics, but Scott tells us that if you want to keep control of your data, then you'll want to have a tool that you have control over too. So Scott reviews these three open source analytics tools, PIWIC, open web analytics, and e-analytics. At number two, we have five open access journals for open source enthusiasts. Joshua Holm writes about five open access journals in celebration of Open Access Week this week. Open Access Week is a global event that runs from October 20th through October 26th and aims to bring awareness to a method of scientific research that is done in the open, and that is through participation, sharing, and transparency. Joshua gives us an excellent background to the cause and on Open Access, so check out his article formal on Open Access and what journals he recommends we read and support. Finally, at number one, we have How Open Stack Powers the Research at CERN. Jason Hibbins interviews 10th L, a member of the Open Stack Board of Directors, and the research scientists responsible for the CERN IT Operating Systems and Infrastructure Group. They provide CERN users with email, web, operating systems, and the infrastructure as a service cloud based on Open Stack. Vell takes us behind the scenes at CERN to show how they have scaled Open Stack on over 3,000 servers without increasing support staff. He will be delivering two talks at the Open Stack Summit in Paris this year, so if you're going or interested in the conference, check out his tips on Open Stack Summit survival in this interview. The links to all the articles are in the notes below and published in the article every Saturday. Thanks so much for joining us and we'll see you next time.
