  2. 2. "The open source process violates everyprinciple of security. It welcomes everyone tocontribute to Linux. Now that foreignintelligence agencies and terrorists know thatLinux is going to control our most advanceddefense systems, they can use fake identities tocontribute subversive software that will soonbe incorporated into our most advanceddefense systems." (Green Hills Software CEO,Dan ODowd)OpenSourceDay 2012

  5. 5. WikiPedia: "Using it is like asking questions of abloke you met in the pub. He might be a nuclearphysicist. Or he might be a fruitcake". P. Valley,The IndependentOpenSourceDay 2012
  6. 6. "In the study, entries were chosen from thewebsites of Wikipedia and EncyclopaediaBritannica on a broad range of scientificdisciplines and sent to a relevant expert forpeer review. Each reviewer examined the entryon a single subject from the twoencyclopaedias; they were not told whicharticle came from which encyclopaedia. A totalof 42 usable reviews were returned out of 50sent out, and were then examined by Naturesnews team.”OpenSourceDay 2012
  7. 7. "Only eight serious errors, such asmisinterpretations of important concepts, weredetected in the pairs of articles reviewed, fourfrom each encyclopaedia. But reviewers alsofound many factual errors, omissions ormisleading statements: 162 and 123 inWikipedia and Britannica, respectively."[Nature, 2005]“the Wiki resource had similar accuracy anddepth to the professionally edited database”[Comparison of National Cancer Institute DBwith Wikipedia, 2010]OpenSourceDay 2012
  8. 8. “Open source mapping certainly has itsbenefits and can be extremely useful,particularly for pedestrians and in city or towncentres. The way that the maps incorporateinput from a wide community of contributorscan result in impressive international coverage,whilst also driving down costs of production.However, when it comes to automotive-grademapping, open source has some quite seriouslimitations, falling shor t on the levels ofaccuracy and reliability required forsafe navigation.” [TomTom]OpenSourceDay 2012
  9. 9. “By means of a variety of studies, we show thatthe difference between the OSM street networkfor car navigation in Germany and acomparable proprietary dataset was only 9%in June 2011. The results of our analysisregarding the entire street network showed thatOSM even exceeds the information provided bythe proprietary dataset by 27%” [HeidelbergU. 2011]OpenSourceDay 2012
