How To Back Up An Ubuntu 8.10 System With SystemImager | HowtoForge - Linux Howtos and Tutorials
by 1 otherSystemImager lets you create images of your Linux installations. To do so, you need an image server (should have enough disk space to store your images) and a so-called golden client (i.e., the system of which you want to make an image). This means that you have to install some software on your image server and on your golden client in order to run SystemImager. This tutorial shows how to install a SystemImager server and a SystemImager client, both using Ubuntu 8.10, and how to create/update/restore/delete images.
Check Your Mysql Server Performance with MySQLTuner -- Debian Admin
by 1 otherMySQLTuner is a script written in Perl that will assist you with your MySQL configuration and make recommendations for increased performance and stability. Within seconds, it will display statistics about your MySQL installation and the areas where it can be improved.
It’s key to remember that MySQLTuner is a script which can assist you with your server, but it is not the solution to a badly performing MySQL server. The best performance gains come from a thorough review of the queries sent to the server, and an evaluation of the MySQL server itself. A qualified developer in your application’s programming or scripting language should be able to work with a MySQL database administrator to find improvements for your server. Once the server and application are optimized well, you may need to consider hardware upgrades to the physical server itself.
This is a really useful tool for helping to optimize MySQL performance.Understanding the various my.cnf variables and how they affect performance can seem really complicated but this tool takes some of the pain away and makes it easier to understand the effects of each variable.It is especially useful to be able to see the global memory usage, memory usage per thread and the maximum possible memory usage - that is really valuable information that is otherwise complex to calculate.

Zuwanderungspolitik: Offene gesellschaftliche Diskussion notwendig
Mit der Einsicht, dass die Einwanderungs- und Integrationspolitik in Österreich gründlich überdacht und geändert gehört, haben Industriellenvereinigung und Wirtschaftskammer Recht. Und es ist lobend anzuerkennen, dass sie die längst ausständige gesellschaftliche Diskussion über diese Themen führen wollen.

Endlich geht der US-Wahlkampf dem Ende zu
Ich ersehne mir das Ende nicht so sehr, weil ich dann, nach dieser schier unendlichen Geschichte endlich weiß, wie der neue Präsident der USA heißt, das ist für mich zweitrangig, sondern weil dann in den Medien vielleicht auch wieder einmal etwas anderes berichtet wird.
