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.

Handheld Computing
Reality Computing Handheld Computing Col. Kenneth L. Alford, Ph.D. U.S. Army Handheld computers, especially personal digital assistants (PDAs), are increasingly being used throughout the Department of Defense. This article highlights some of the ways that PDAs are used today and are envisioned for the future. It outlines some of the considerations involved in a PDA procurement, discusses four tools for developing PDA resource materials – pro- gramming tools, hypertext markup language- and eXtensible markup language-based tools, text tools, and calendar tools – outlines some of the benefits and challenges associated with using PDAs, and shares several lessons learned. omputing power continues to increase copy of the complete daily list.

A 'World' of Information in Your Pocket
Vol. 03, No. 4 / April 2004 A ‘World’ of information in your pocket Transferring online information onto your PDA provides the World Wide Web’s benefits without the connection. John Luo, MD Assistant professor of psychiatry UCLA Neuropsychiatric Institute and Hospital Los Angeles, CA With wireless Internet available in hospitals, coffee shops, airports, universities, and libraries, real-time Internet access away from the home or office is just a click away on your personal digital assistant (PDA). But what if you’re somewhere without wireless Internet-such as in flight or at the local department of motor vehicles? Transferring and storing online content onto your PDA lets you access critical online information in places without a connection, making your down time more productive. PORTABLE ONLINE CONTENT Much Web-based information can easily be captured or stored onto your PDA. Electronic books, or e-books, have long been one of the pleasures of using PDAs and handheld devices such as the Franklin eBookMan. Many e-books are available for free or for purchase at numerous Web sites. Medical text vendors such as Skyscape and Handheldmed offer a range of titles, including the DSM-IV-TR and the Washington Manual Psychiatry Survival Guide. Clinical literature. Many journals and medical periodicals offer Adobe Acrobat portable document format (PDF) versions of print articles, but these are often available only to subscribers. Most online content is copyrighted. As long as the material is captured for personal use and is not distributed, however, there should be no legal ramifications. TEXT TRANSFER OPTIONS The easiest way to import text into your handheld is to select text with your mouse, copy the text, paste it into a Microsoft Word document, and transfer it onto your PDA. -
Image File Formats, Digital Archival and TI/A
Image File Formats, Digital Archival and TI/A Peter Fornaro & Lukas Rosenthaler A Short Introduction into Image File Formats 1 1 Introduction In general, long-term archival of digital data is a difficult task. On one hand the media, where the digital data is recorded on may be instable and decay with time. On the other hand, the rapid evolution cycle of digital technologies which is measured in years or even months leads to the obsolescence of recording technologies at a fast pace. Old1 data carriers may not be read anymore because the necessary machinery (tape reader, disk interface etc.) is no longer commercially available. Also, the the information about the file formats – that is the information about the meaning of the bits – may be lost because new formats have become standard. Thus, digital archiving is basically the task of guaranteeing the meaningful reading and decoding of bits in the far future. This task can be divided into parts: Bitstream preservation It has to be guaranteed that the bits which are basically analogue symbols on a analogue medium2 can be correctly detected. Since most often the permanence of the bits is higher than the lifetime of a given recording technology, bitstream preservation is basically limited by the obsolescence of a given recording technologies. Thus, copying the bits onto a new data carrier using the latest technology just before a recording technology becomes obsolete will preserve the bitstream. This task called bitstream migration has to be repeated every 3 - 5 years. Since a bitstream can be copied without information loss and the copies will be identical to the “original”, this process can be repeated an indefinite number of times (contrary to analogue copies where each generation is affected by more degradation until all information is lost). -

Lidija Mandić I would like to thank my advisor Federico Peinado and co-advisor Lidija Mandić for their help and support throughout this work. Martina Brajkovć autoriza a la Universidad Complutense a difundir y utilizar con fines académicos, no comerciales mencionando expresamente a su autor, tanto la propia memoria, como él código, los contenidos audiovisuales incluso si incluyen imágenes de los autores, la documentación y/o el prototipo desarrollado. Martina Brajković ABSTRACT Electronic books are electronic copy of a book or a book-length digital publication. In the past decade they have become very popular and widely used. Each day more and more publishers digitalize their textbooks and more and more devices are suitable for reading of the electronic books. Huge changes in human communication happened in the late 20th and early 21st century. Due to invention of Internet, information became widely available which changed every segment of human life, especially education. One of the most important applications of electronic books is electronic learning. Electronic learning includes various types of media, such as video, audio, text, images and animations. Interactivity of an electronic book can increase the attention in the classroom and result with better educational performance In this work the process of creation of an interactive electronic book is researched and analyzed. The process includes use of popular Adobe software: InDesign, Photoshop, Illustrator, Captivate and Edge Animate. -
