Changes

The first part of the presentation is generally, highlighting the open source definition from the internet such as opensource.org, microsoft.com, etc. They highline some of the key definition such as: free redistribution, project must include source code, derived works, integrity of the author’s source code and distribution of license.  The second part of the presentation is suppose to be about open commercial development, which is suppose to be a new hybrid development model that takes aspects of both the open and proprietary development models to provide a new model for the commercial software development process as defined in the symposium event description but based on what I understand from the talk, open commercial development is not a new development model that is created by IBM. Instead, it is an old development modal that has failed many times based on historic facts. The word, “open” in open commercial development is extremely misleading because open commercial development is not open source. Basically, open commercial development is a transparent development process for which they get user to participate when they are developing new software. In general, they are trying to apply open source technical to development as oppose to what they usually use a “closed” development modal. By applying the open source technical, they are trying to get direct customer involvement into project in order to improve software quality. I find the material and strategy which they have presented to be very similar to the agile development technique and they are trying to make money out of the free direct customer and open opening source community input without crediting the contributor. ==Speaker and Speaker’s Views on Open Source==I find the view on open source from the speakers of the two presentations to be completely different. “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 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 to be trying to convert open source into something that is profitable but I do not know enough to understand this.
