When I began collecting links for the Linux Sound & Music Applications pages I frequented a variety of announcement and news services. Some of those services are no longer with us, some have been superceded by more comprehensive and modern channels, and a few have remained as primary sources for new and updated Linux audio software. SourceForge is one of those long-lived services that have remained relevant to my searches for new and interesting sound and music applications, so I decided to surf the Forge to find recent and maybe some not-so-recent developments in the world of Linux audio.

VirtualBox is a free, powerful and versatile virtualization program which is available for Linux, Mac, and Windows hosts, and can virtualize many different Operating Systems. VirtualBox was originally developed by Innotek, but was purchased by Sun and renamed Sun xVM VirtualBox.

In this article I finish the process we started in the last episode. Read on for the thrilling denouement. The Build After all the preparation described in the first part of this article the build process itself is rather anticlimactic. Building from sources with the GNU autotools is this easy :

OpenOffice.org: The limits of readability and grammar extensions As a professional writer, my software needs are simple. Give me a text editor -- preferrably Bluefish, but vim or OpenOffice.org Writer will do -- and I have all I need.

The bash function presented here normalizes path names. By normalize I mean it removes unneeded /./ and ../dir sequences. For example, ../d1/./d2/../f1 normalized would be ../d1/f1.

Notify-send is a great application for notifying you when an event has occurred. An event such as a script running to completion. If notify-send is not installed on your machine already, install the package "libnotify1" (or possibly just "libnotify") from your repositories.

Recently I've received some mail asking for a brief explanation on how to build Linux audio applications from source code packages. Ask and ye shall receive, hence the following simple guide for the perplexed, the puzzled, and the downright mystified. Compiling software is hardly rocket science, and if an old guitar-picker like myself can do it certainly you can too.

In my last article I wrote about accessing a PostgreSQL database in C/C++. In this article, I'm going to discuss performing the same functions in C against an SQLite database. Unlike Postgresql and the supporting libraries, SQLite creates completely self-contained databases that aren't dependant upon a client-server architecture.

Quoting things in bash is quite simple... until it isn't. I've written scripts where I'd swear 90% of the effort was getting bash to quote things correctly.
