Last week there was a talk about OwnCloud on floss weekly. OwnCloud is something like Dropbox, Box, Google-Drive, but it runs on your own server, so you have full control over your data, which is getting more and more important in times like this, and i am not talking only about the NSA issue. so if you are interested to create your own service for storage and sharing files, owncloud is a very good choice. owncloud can also do much more then dropbox, so check it out! here you can find the talk on flossweekly about owncloud.
