The major difference that I noticed between the community edition and the enterprise editions is sync application availability for mobile devices. These applications are not available for the community edition but it does not cause any problem for our local installation because teachers used it to keep their work on laptops in sync with school server. I have not heard any request from any teacher to sync it with their mobile devices.

Guest Access, Workflows (Automated File Operations), Full Text Search, Password Policy is also not available in the community edition but these things are not needed at small scale level. As to the full text search, a copy of all these files  is always available on desktops so one can use windows and mac features to search through files if one has to do full text search. Limitations only apply when one try to access files form the web interface. Password policy defines character length, character types for user password.

 I live in Shanghai in China. Most of foreign-hosted (non-Chinese) Cloud-storage websites do not work here. As a solution to this problem, I installed owncloud on school server to allow all teachers to use school-based cloud storage system. Today, I found one cloud hosting site that still works in China. This is flipdrive.

It provides 10 GB Cloud Storage, 25 MB File Size Limit, Up to 10 File Sharing Links and Up to 10 Folder sharing for free as its basic plan. If one need more space then the basic plan can be upgraded to the personal plan, that offers 25 GB Cloud Storage, 1 GB File Size Limit, Unlimited File Sharing Links, Unlimited Folder Sharing and Direct Links to Files. Moreover, it also provides the mobile application to keep your photos, contacts, and bookmarks synchronized with one’s cloud storage. I don’t think I will use because sooner or later it is going to be blocked here. There are better services like dropbox and one driver available but they are blocked in China.

 Description:

First I selected a topic that can be suit use of this form of media. After that, I modified the PowerPoint presentation that I used to teach F2F classes. Then I prepared script to narrate with the screen cast. I had downloaded Screencast-o-Matic to record my screen but my computer’s audio input has some problem. So I could not record my voice. Then I used my phone to record my voice. Then I have Chinese cloud software on my phone and PC to transfer audio files. Then I used Audacity to trim some “ums” of my audio files. I saved my PowerPoint slides as images and imported images and audio file to the windows Movie Maker. Then next challenge was to sync audio with slides. That took about two hours. Windows movie maker always forget to import last few seconds of my audio files so I had to use audacity to cut last few seconds from my original audio file and then I imported that into the Movie Maker. I wonder if other people also have the same problem with the movie maker. If you have any solution to this problem then please let me know.
