How to install (Oracle) Sun Java SDK 1.6.x (Java 6) on Ubuntu

Dieser Beitrag beschreibt die Installation des Sun Java SDK 1.6.x on Ubuntu (Maverick). The English explanation on how to install Sun Java SDK 1.6.x can be found here.

Canonical-Partner Repositories aktivieren:

Dies geschieht unter “System” -> “Systemverwaltung” -> “Synaptic Paketverwalung”. In der Paketverwaltung finden sich die Paketquellen unter dem Menüpunkt “Einstellungen”. In den Einstellungen wechselt man auf den Reiter “Andere Software” und aktiviert dort “Canonical-Partner” bzw. “Canonical-Partner (Quelltext)”.  Nach dem Klick auf “Schließen” werden die Paketlisten neu geladen.

Terminal öffnen und Java 6 JDK installieren:

[sourcecode]
$ sudo apt-get install sun-java6-jdk
[/sourcecode]

Java Version zur Standardversion auf dem System machen:

[sourcecode]
$ sudo update-java-alternatives -s java-6-sun
[/sourcecode]

Für das aktuelle Java Development Kit wird der Symlink /usr/lib/jvm/java-6-sun erstellt. Dieser zeigt auf die aktuell installierte Version des JDK.

Installation überprüfen:

[sourcecode]
user@ubuntu:~# java -version
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode)
[/sourcecode]

Damit ist die Installation abgeschlossen.

Vielen Dank an Michael Noll für die englische Installationsanleitung, die ich als Vorlage verwendet habe.

Google’s SEO Starter Guide – How to improve your website

Google's SEO Starter Guide: How to improve your website.

Webmasters often ask us at conferences or in the Webmaster Help Group, “What are some simple ways that I can improve my website’s performance in Google?” There are lots of possible answers to this question, and a wealth of search engine optimization information on the web, so much that it can be intimidating for newer webmasters or those unfamiliar with the topic. We thought it’d be useful to create a compact guide that lists some best practices that teams within Google and external webmasters alike can follow that could improve their sites’ crawlability and indexing.

What he and his group did was to create a compact guide called the “Google SEO Starter Guide“. There are lot’s of DOs and DON’Ts published. Every blogger and every website owner should have a look on this paper.

We felt that these areas (like improving title and description meta tags, URL structure, site navigation, content creation, anchor text, and more) would apply to webmasters of all experience levels and sites of all sizes and types.

TheNextWeb is supprised about Google’s step:

In a slightly surprising move, Google has launched via its webmaster central blog a best practice guide for search engine optimization.  Why surprising you may ask? Well, Google is notorious for being pretty quiet on this front leaving it to SEO’s, designers, and developers to figure out what works best.

Netzlogbuch states out that the start guide copes basic things that nearly everybody already knows. Well for sure it is helpful for many people out there.
