3 Funding One group - unlikely get enough funding to accomplish all goals GLEON as group – harness all potential developers and testers –Increase developer collaboration and cyberinfrastructure sharing

4 Adopt Free Software Model Free Software Model (Free as in Freedom) –Adopts scientific community approach to software development Code (ideas) freely available and reusable Encourages building and improving on the software (ideas) of others –Like sharing methods, lab, and staff At no cost!

5 Standing on the shoulders of giants Group 1Group 2Group 3 Group 1 Group 2 Group 3 Group GLEON

6 Open Source/Free Software Open Source <> Free Software Free Software (Free as in Freedom) –Anyone can take, distribute, alter –Copyleft Open Source –Source code available –No further rights necessarily given

7 Countless Examples R Firefox Thunderbird LakeAnalyzer was first success –Received feedback on schmidt stability calculation

8 Half Baked Idea #2 Parallels in GLEON –Grassroots organization –Grassroots data collection –Grassroots science –Grassroots QA/QC?

9 Grassroots QA/QC Create a mechanism for all to contribute –Any potential issues marked –Those responsible for specific dataset notified Example –Chris finds and marks problem –Luke is notified –Examines data, confirms problem, adds additional description –Result: Better vetted data
