ensemble_1I came across by chance in what I consider one of the more comprehensive guide to creating audio in Linux, and Stefano gave me the permission to republish his material that I consider really good and that he uses as musician.

Stefano it’s an Ubuntu user and his guide it’s based on this distribution, he’s really active in the Ubuntu italian community, if you want to make him a question regarding his guide, you can post in this thread http://forum.ubuntu-it.org/index.php/topic,278719.0.html, the language of the forum is Italian, but i’m sure that you’ll get some answers also if you ask kindly in English.

This is part 1, i plan to republish the whole guide in 4 parts in the next days.
The original article is in italian, if you have any comment about the translation, contact me.

Introduction

When a server environment is created using virtualization software or a cloud service, the number of servers tends to increase rapidly. Software installation and configuration are required every time a server is created. Further, synchronizing server configurations requires additional effort such as writing shell scripts.

In this article, we will describe how to build a server environment automatically using a relatively new software tool called Puppet. Although this tool is typically used to manage large-scale server infrastructure (such as a data center or a Web service with a large number of users), it can also be used to manage a small number of servers. However, Puppet is a newly developed tool, and the existing documentation and the articles on Puppet are still somewhat cursory.

Today i want to show you some examples done with Zenity.

Zenity is a cross-platform program that allows the execution of GTK+ dialog boxes in command-line and shell scripts.

Like tools such as whiptail and dialog, zenity allows for easy creation of GUIs, though it has fewer features than more complex GUI creation tools: “Other scripting languages such as Perl and Python can be used to construct full-scale GUI applications, but the zenity program enables a shell script to interact with a GUI user…. [The] user interface is not as refined as one that could be provided by a full-featured GUI application, but it is perfectly suitable for simple interactions.”
