“Code Code Reading and Review” is presented by Benjamin Smedberg from Mozilla Cooperation. He has been involved in the open source community for a long time and I feel that he understand the open source community very well. He made a lot of critical suggestion and recommendation to us on how to create, control, lead, use, and work in the open source community. I find his suggestion to be very useful and productive. “Open Open Commercial Development” is presented by Lawrence Mandel and Jeffrey Liu from IBM Canada. They seem to be new to open source as during the presentation, I feel that they are trying to understand what open source is as well. For many time, they have mentioned the definition of open source is different from people to people and I often got confused during their presentation because they often mention how open commercial and different from open source while what they explained as open commercial is identical to the agile development technique. They seem Maybe I got it completely wrong, they are just trying to improve the quality of the program by creating a new development model based on open source but they made but their explanation on open commercial development is as if they are trying to be take advantage of open source while renaming agile development technique into something that as already exist and make it their own. Sometime they made me feel that they are just trying to convert open source into something that are more profitable. That is profitable understandable in a business prospective, but I do not know enough to comment on thisin a way it completely destroys the idea of “free software” and “open source”.
