The Indiana Affordable Classroom Computers for Every Secondary Student (InACCESS) grant program has placed more than 22,000 workstations in 24 high schools across Indiana. 1
- 23. Success Stories InACCESS “ Kevin McGuire at Michigan City Area Schools stated that additional technical support staff has not been required; the existing five-member team supports all 3,500 machines.” 1 “ According to McGuire, teachers are getting up to speed with comparatively little training.” 1
- 24. Success Stories InACCESS “ By the second year, Alexandria Schools was so pleased with the results that it installed three additional one-to-one classrooms using its own funds (about $25,000 per classroom). This time Ice opted for no hard drives and a thin client from Linux Terminal Server Project (LTSP). He was concerned about extra heat from all the new computers and thought that removing the hard drives was one way to manage that issue. That solution is expected to greatly reduce the complexity of technical support.” 1
- 25. LTSP ? The Linux Terminal Server Project adds thin-client support to Linux servers. LTSP is a flexible, cost effective solution that is empowering schools, businesses, and organizations all over the world to easily install and deploy desktop workstations. A growing number of Linux distributions include LTSP out-of-the-box. 2
- 26. Success Stories University of North Carolina School of Medicine "Going with an open-source application saved the school plenty of money by avoiding the need for licensing fees, according to Charlie Hitlin, manager of application development and media services for the UNC-CH SOM.
