In Coles all public computers, both Macs and PCs, have PowerPoint installed. There are several strategies available for those who want to run PowerPoint presentations from Coles computers. The appropriate strategy will depend on the individual and, to a lesser degree, on the characteristics of the presentation itself. If the presentation is be a formal part of the curriculum, the author should arrange with Academic Computing to have the file mounted on Endeavor. If you have access to a web server.
Many people have their own web sites.
Those with NYU Home accounts might use those sites for this purpose. Post the resulting files to an appropriate directory on the web server. Start PowerPoint and open the presentation in the usual way. Note that presentations and other files saved to Coles computers will not be retained indefinitely. As maintenance on the machines is peformed such files are unceremoniously deleted.
