Lu | Kindle 3.X updater for Kindle 2 and Kindle DX released
After a month and a half of testing thanks to the community of MobileRead, I can finally release the first stable version of the Kindle 3.X software updater (help me come up with a better name, please). If you haven’t read my last few Kindle-related posts (read them if you want more technical details of this script), you should know that this allows you to use all the cool new features of the Kindle 3 on a K2 or DX device. Installation is easy and is only three steps: 1) Use “prepare-kindle” script on old Kindle to back up and flash recovery kernel, 2) Copy generated files to Kindle 3 along with “create-updater” script and run it, 3) Copy generated update package back to old Kindle and restart. If that sounds confusing, don’t worry, the readme contains very detailed directions and even how to recover in case anything goes wrong. Here it is.

The tutorial lessons are contained in zip files on the SourceForge project web site. Each lesson is contained in a separate zip file called <name>lessonxx.zip, where <name> is the tutorial name (e.g., totalbeginner, persistence, debugger, workbench), and xx is the lesson number. For example, the zip file for the Total Beginners lesson 1 is called totalbeginnerlesson01.zip. The Lessons can be downloaded from the download site for each tutorial, either using the Download Tutorials links on the left side of this page or using the Download link on each tutorial's Main Page. All of the tutorials, except for the Total Beginners, also have a zip file that contains a project archive file (e.g., workbench-tutorial.zip, persistencetutorial.zip, etc.). Each project also includes a PDF document called the Tutorial Companion Document. You can play Lesson 1 of each tutorial without downloading anything, just by clicking on the "View Lesson 1" link in each tutorial's main page. Playing the Videos
Installing Jenkins on Ubuntu
On Debian-based distributions, such as Ubuntu, you can install Jenkins through apt-get. Recent versions are available in an apt repository. Older but stable LTS versions are in this apt repository. You need to have a JDK and JRE installed. openjdk-7-jre and openjdk-7-jdk are suggested.

Jenkins will be launched as a daemon up on start. by sudo a2dissite default
Sonderzeichen unter Mac OS – MacEinsteiger.de
Eines der größten Probleme in den ersten Tagen mit Mac OS ist für Neulinge wohl die Benutzung der Sonderzeichen. Waren die gängigsten Sonderzeichen auf handelsüblichen Windows-Tastaturen noch aufgedruckt oder man erreichte sie über eine Zahlenkombination, so sucht man auf einer Mac-Tastatur teilweise vergebens. Diese Übersicht kostenlos als PDF downloaden. Aber wo findet man die nicht abgebildeten Sonderzeichen, wie zum Beispiel die “eckige Klammer auf” (“[“), “Backslash” (“”) oder das “Tilde“-Zeichen (“~”)? Apple Mac OS bietet dafür eine Tastaturübersicht an, die Ihr wie folgt erreicht: 1. in den Systemeinstellungen -> “Tastatur” 2.

Kay Hortsmman - Core Java Web Page
Both volumes are available as e-books: Volume I—Fundamentals | Volume II—Advanced Features Core Java by Cay S. Horstmann and Gary Cornell was originally published in the Java series of Sun Microsystems Press and is now published by Prentice-Hall. “What makes Core Java the definitive work on the language is more than its vast scope—it is the quality of the presentation.” “Cornell and Horstmann make the details of this powerful and expressive language understandable, and they also furnish a conceptual model for its object-oriented foundations.” “Devoid of shaky, academic examples and packed with robust demonstrations that illustrate hundreds of powerful concepts...The authors back up the many examples with sharp, fact-rich commentary on how to get things done with Java.” Winner of the 2003 Jolt/Software Development Productivity Award! About the Authors Cay S. Gary Cornell has authored or co-authored 14 popular computer books and articles for many developer magazines. Further Information
