Installation - Goggles Music Manager:
OpenSUSE packages are provided by the PackMan project.
After successful installation you can find Goggles Music Manager

Application → Multimedia → Jukebox → Goggles Music Manager

The first time you start Goggles Music Manager, it will come up with a empty song database. In order to enjoy your music collection you first need to fill up the song database.

To add songs to the database, open up the Music menu and select "Import Folders". It will pop a dialog asking you to select from which directory you like to add songs from.

Once you press "Ok", Goggles Music Manager will add all Ogg Vorbis files located in the chosen directories and its subdirectories. Note this may take a while when you a have huge collection of songs. You only need to do this once. If you want to add new songs to the database use the "import" command in the Music menu.

If everything was successful, the database should have been filled up. Select any genre, then artist, and finally select the album and double click on the song you want to listen to.

tutorial - WineXS - GUI (Graphical User Interface) for Wine

Wine makes it possible to run Windows programs alongside any Unix-like operating system, particularly Linux. At its heart, Wine is an implementation of the Windows Application Programing Interface (API) library, acting as a bridge between the Windows program and Linux.

Think of Wine as a compatibility layer, when a Windows program tries to perform a function that Linux doesn't normally understand, Wine will translate that program's instruction into one supported by the system. For example, if a program asks the system to create a Windows pushbutton or text-edit field, Wine will convert that instruction into its Linux equivalent in the form of a command to the window manager using the standard X11 protocol.

WineXS is a GUI (Graphical User Interface) for Wine. WineXS allows you to easily configure Wine by installing and removing software, editing the registry, managing files, and more.

Installation:

Download WineXS from here
Extract it to a directory: tar -zxvf winexs-1.4.2.tgz
Move inside the extracted directory: cd winexs/
Run WinEXS: ./winexs

Software Installation screen:

Install MS fonsts screen:

tutorial - Backup & Restore MySQL Databases - MySQLDumper

MySQLDumper is a backup & restore management script for MySQL Databases, written in PHP and Perl, which fills this gap and offers a complete control over the databases.

MySQLDumper uses a proprietary technique to avoid execution interruption. It only reads and saves a certain amount of commands and then calls itself via JavaScript and memorizes how far in the process it was and resumes its action from its last standby.

MySQLDumper offers to write data directly into a compressed gz-File. The Restore-Script is able to read this file directly without unpacking it. Of course you can use it without compression, however using Gzip saves a sizable amount of bandwidth.

Installation & Configuration
* Download MySQLDumper - Here
* Extract the zip file under your webserver root directory: unzip msd1.24RC1.9.zip, this command will create a new directory msd1.24
* Lunch your browser and point to the msd1.24 directory, this will open up the installation wizard which is very simple and straight forward.
* After successful installation point your browser to "index.php" to open up the main application from where you can take & restore backup

Features:
MySQLDumper can read Dumpfiles from other Scripts via the integrated parser (for example from phpMyAdmin)
- Security: MySQLDumper can generate a .htaccess-file to protect itself and all of your backup-files
- MySQLDumper can do Multipart-Backups. That means: MySQLDumper can automatically split the dumpfile if it gets bigger than your chosen size. When you want to restore a backup and choose the wrong part - it doesn' matter: MySQLDumper will notice that and will get the correct startfile automatically.
- automatic Errormodul
- MiniSql: You have access to your MySQL-Tables. You can delete tables, edit or insert data. You can run/ save any SQL-Statement.
- Database-Overview: look at running processes or even stop them
- very good file-overview: backups of the same database are shown as one entry. Click it to see all of the files.
- automatic file-deletion: set your own rules to delete old backups. Specify the age or the number of files when it will be deletetd automatically to save server webspace.
- Perl Cronscript done: all features of the PHP-Script are now integrated in the Perlscript that can be started via a Cronjob
- Configuration can be set seperatly for each Script (PHP and Perl)
- befor you start a backup all your parameters are shown again, so you definitely know what you are doing :-)
- Send Emails with or without your dumpfile attached / you can set the maximum size of the attachement. If it grows bigger it won't be attached.
- Send dumpfiles via FTP to another Server. This is also working using the multipart feature.

tutorial - Kernel Compilation & Installation on Ubuntu - KernelCheck

If you’ve ever tried compile a linux kernel yourself you know the headache of configuring and taking care of dependencies. KernelCheck makes this a point and click process for debian based linux distributions such as Ubuntu. You can use it to compile and install any 2.6.* stable kernel as well as the bleeding edge.

KernelCheck even offers custom compilation options such as including kernel patches or rolling in proprietary video drivers. A tutorial (PDF) is also provided so you can see what you’re getting yourself into.

KernelCheck is a graphical user interface program designed to make the kernel-compiling process as easy as the click of a button. A kernel is the base of any operating system – in our case, the Linux operating system.

KernelCheck will fetch the latest information from http://www.kernel.org, which hosts the source packages for the Linux kernel, and ask the user which one they would like to compile into a .deb package (with the option of installing the kernel after the compilation). This automated process is a fork of AutoKernel by Robert Wolterman (xtacocorex), Timothy Janssen (mentok), and Kristof Verbeken (PingunZ). KernelCheck is currently licensed under the GNU Public License version 3.

Installation:
   1. Download the KernelCheck source here.
   2. Unpack the archive: tar -xzf kernelcheck-*.tar.gz
   3. Install KernelCheck

cd kernelcheck-*
sudo python setup.py install

4. Use it: sudo kernelcheck

The basic things the program will show you are:
   1. Your running kernel
   2. The latest kernel
   3. The latest kernel patch

Now on to building the kernel. Under Kernel Patch Options, select the option that you wish to use. Unless you know what you're doing, I strongly recommend using the default selected.

Under Advanced Options, you can choose whether you want to configure the kernel options, reconfigure the X server, and install an nVidia module. The nVidia option will remove any nVidia-related packages, any binary version installed, and install the latest one. This will remove nVidia support for older kernels until you run the binary file in /usr/src with the -K option with every new kernel you use, not compiled with KernelCheck. It is strongly recommended that you configure the kernel options yourself, mainly to make sure your hardware is supported. Now to build the kernel, all you have to do is go to Program > Build New Kernel.

tutorial - Windows 7 Sins: The case against Microsoft and Proprietary Software

The new version of Microsoft's Windows operating system, Windows 7, has the same problem that Vista, XP, and all previous versions have had -- it's proprietary software. Users are not permitted to share or modify the Windows software, or examine how it works inside.

The fact that Windows 7 is proprietary means that Microsoft asserts legal control over its users through a combination of copyrights, contracts, and patents. Microsoft uses this power to abuse computer users. At windows7sins.org, the Free Software Foundation lists seven examples of abuse committed by Microsoft.

You can help!
Free software operating systems like GNU/Linux can do the same jobs as Windows, but they encourage users to share, modify, and study the software as much as they want. This makes using a free software operating system the best way for users to escape Microsoft and avoid becoming victims of these seven sins. Software and computers will always have problems, but by using free software, users and their communities are empowered to fix problems for themselves and each other.

You can get more information about each of the sins and how to escape them at windows7sins.org. Please sign up there for campaign news and action alerts to help raise awareness about Microsoft's abuses, the problems with Windows 7, and the importance of free software!

tutorial - Free Disk Space by Reducing Reserved Blocks Percentage

In a default install Linux reserves 5% of the disk space for privileged processes. It is a precautionary measure on part of Linux to keep up even after the file-system is filled up.

With this approach it allows root to conduct administrative activities on the partition and perhaps move some data off. However, this is most critical when the partition contains / or home directories. For pure data partitions, this is just lost space. Five percent of a 250Gb partition is 12.5 Gb. Especially in the case of large partitions, it is safe to set the reserved space to the minimum, which is one percent or even to 0 percent.

There are two ways through which you can adjust this reserve percentage

1) At the time of creation of file-system:

# mkfs.ext3 -m 1/dev/sda1 (replace sda1 with your partition name)

The above command creates a file system with only 1% of its space reserved for the root user.

2) After creation of file-system:

You can use tune2fs utility to reduce reserved blocks in ext2, ext3 as well as ext4 file-systems. To reduce reserved blocks to 1% use the following command:

# tune2fs -m 1 /dev/sda1 (replace sda1 with your partition name)

In a 1 TB hard drive you can save upto 37GB of space after applying this tweak.

tutorial - Howto Benchmark Linux System - HardInfo

Benchmarking means measuring the speed with which a computer system will execute a computing task, in a way that will allow comparison between different hard/software combinations. It does not involve user-friendliness, aesthetic or ergonomic considerations or any other subjective judgment.

HardInfo is a system profiler and benchmark for Linux systems. It can gather information about your computer and operating system, perform a variety of benchmarks, and export the data to HTML.

Installation:
OpenSuSe 11.1 users can use "1-click" installer - here
Ubuntu users can install Hardinfo via the terminal using: sudo apt-get install hardinfo

The easiest way to browse the reports is to run them all by generating an HTML page. Click the Generate Report button on the toolbar, and select the information you want included. Generating a report including the benchmarks could take a few minutes depending on how fast your computer is.

If you are unsure about how to interpret the results, Hardinfo displays a line towards the bottom – giving you some additional information about the test results.

tutorial - Install 150+ Games on OpenSuSe using "1-Click" Installer - GameSore

Wouldn’t it be great if there was an application which would allow users to browse through games, filter them by genres or names, view the screen shots and read the information about the games? Players using Windows can already use “Games for Windows” or “Steam” from Valve, but they also have to pay for the majority of the games.

All games in repository are free and just one click away! so to bring the same thing into Linux there is a project called "GameStore" an application written in Qt that contains more than 150 titles of games and those can be installed using the convenient 1-Click-Install.

Installation of GameStore:
OpenSuse 11.0 - here
OpenSuSe 11.1 - here

After successful installation, go to terminal and type command gamestore to start the application and you should see something like ...

As you can see, GameStore is at the moment quite immature Qt application, but it is already able to load locally stored XML together with game icons, screenshots and descriptions. User can install new games (using great One Click Install feature) and launch the installed ones later
