Distributed Clipboard – file sharing components

Hey again! Since I used my last post to show you the difficulties I experienced during implementing Drag&Drop in combination with JavaFX 2.0, I today want to introduce my file sharing components. After a DropEvent is registered on the GUI (see last post), a new thread responsible for transferring the dropped files is launched. Creating [...]

Tweetflow Natural Language Generation

Hi, My Praktikums-Topic is about creating an Android client for generating natural sentences out of Tweetflows. As you might have read already, Tweetflows are used to create mobile workflows.

Although i promised to publish my third blog entry already the week before, I have to admit that I wasn´t able to write about my filesharing and chat components as announced, because I ran into some serious problems the last 2 weeks, regarding the further implementation of the GUI.

A lot of attributes are needed to be general enough to save all the different types of requests. The last four attributes are needed to save the ordering of closed sequences. One has [...]

The most general string pattern to extract the whole request text of all the different request [...]

Accessing twitter-like services via OAuth

After playing around with the twitter4j library to get it to work with my own network configuration (e.g. mentioned in an earlier post I ended up in searching for another solution, as twitter4j cost me already too much time.

Android Action Bar widget
