Prepared exclusively for Alison Tyler Download at Boykma.Com What readers are saying about Ubuntu Kung Fu Ubuntu Kung Fu is excellent. The tips are fun and the hope of discov- ering hidden gems makes it a worthwhile task. John Southern Former editor of Linux Magazine I enjoyed Ubuntu Kung Fu and learned some new things. I would rec- ommend this book—nice tips and a lot of fun to be had. Carthik Sharma Creator of the Ubuntu Blog (http://ubuntu.wordpress.com) Wow! There are some great tips here! I have used Ubuntu since April 2005, starting with version 5.04. I found much in this book to inspire me and to teach me, and it answered lingering questions I didn’t know I had. The book is a good resource that I will gladly recommend to both newcomers and veteran users. Matthew Helmke Administrator, Ubuntu Forums Ubuntu Kung Fu is a fantastic compendium of useful, uncommon Ubuntu knowledge.

Abstract: Nowadays, everybody uses web applications. Despite of their advantages, like being available at any place with Internet, they have some usability problems with regard to common desktop applications. This article tries to analyze the possible solutions in order to interconnect desktop and web applications, centered in the GNOME platform and using RTM-GLib as example and study case. Table of Contents Introduction 2 State of the art in the GNOME platform . .2 Goals .......................................7 The library: RTM-GLib 7 Dependencies . .7 Development . .8 License ......................................8 Roadmap . .8 Usage example . .9 Future ideas 9 Mojito.......................................9 Trackerminer................................... 10 EDSbackend................................... 11 Conclusion 11 1 Introduction There are a large amount of web services in the Internet. A general deﬁnition of web service said that it is a system which provides an interface to allow interaction between machines over a network. As time passes more and more web applications provide some kind of API in order to access their services. This number is growing and it seems that will keep growing for some time. Some examples of these applications: Flickr, Facebook, Twitter, etc. Web applications has some advantages compared with desktop applications: All the data is shared and in a centralized place. They do not need any special conﬁguration or installation, just a simple web browser is enough.
