apeinfo is CLI (command line interface) program designed to display tag data and audio format information for APE (Monkey's Audio) files.

Monkey's Audio is a lossless audio compression format, similar to FLAC.  It's become fairly popular, but suffers from two primary limitations; very limited cross-platform support (only Windows is officially supported), and a non-free license (note: this may have recently changed).  As a result, I wanted an easy way to convert APE files to the FLAC format, which is my preferred lossless compression format.  There are no available CLI APE tag readers available for Linux at the time of this writing, so I modified a sample program included in the MAC distribution to output this information.  I then use this information in my Convert to FLAC script to migrate the APE tags to the new FLAC file.

innotek VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.






Some of the features of VirtualBox are:




• Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
  
• Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.
  
• Guest Additions for Windows and Linux. VirtualBox has special software that can be installed inside Windows and Linux virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window).
  
• Shared folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox allows for declaring certain host directories as "shared folders", which can then be accessed from within virtual machines.
