If you have an audio card (or some people call it sound card) that supports multiple outputs and actually using it for different purposes such as playing games, watching movies & listening to music, you’ll have to go through the hassle of changing the audio output in Windows Vista Control Panel.
Here’s an example. Let’s say you have a headphone and speakers. In order to change the audio output, you’ll have to close the program that is currently outputing the audio and right click on the speaker icon, choose Playback Devices, right-click on the playback device that you want and select Set as Default. Then click OK to close the sound configuration window and relaunch the program and play the audio. That will make it change from one output to the other, but it is troublesome and involves many steps.Read more

sipX ECS (Enterprise Communications Server) is an open source voice over IP telephony server. Its main feature is a software implementation of the Session Initiation Protocol (SIP), which makes it an IP based communications system (IP PBX). Featurewise, it is not unlike Asterisk, a very popular open source PBX, but the design of sipX deviates from Asterisk in many ways. Development started in 1999, but in 2004 Pingtel Corp contributed the codebase to the non-profit organization SIPfoundry. It is an open source project since then. Pingtel assets were acquired by Nortel in 2008 and Nortel continued to support the project with several key enhancements and additions. Subsequent to the Avaya acquisition of Nortel in December 2009, Avaya has backed out of sipXecs and SIPfoundry. Former members of Pingtel and Nortel have create a new commercial entity call eZuce, Inc. (www.eZuce.com) to carry sipXecs forward? and provide commercial versions of the software and support. Source code acquired by sipX is available under the GNU Lesser General Public License (LGPL) as well as a commercial offering from eZuce Inc.Read more
Like dd, dd_rescue does copy data from one file or block device to another.dd_rescue is a tool to help you to save data from crashed partition. It tries to read and if it fails, it will go on with the next sectors where tools like dd will fail. If the copying process is interrupted by the user it is possible to continue at any position later. It can copy backwards.Read more
With tinc you can create a virtual private network (VPN) that lets you communicate between two machines over an insecure network such as the Internet with all of your traffic encrypted between the hosts on your virtual network.
Another interesting application for tinc is connecting your laptop to a Wi-Fi router at home. You might already be using WPA2 to ensure that only valid hosts can connect and communicate with your Wi-Fi router, but you might not be able to assign a fixed address to the laptop when it is connected over Wi-Fi. So if you want to connect to an SSH daemon on the laptop itself or access an NFS share on the laptop, you have to play guessing games as to which IP address the Wi-Fi router has given the laptop this time. Running tinc on the laptop and a server at home removes the guessing game -- just connect to the laptop's VPN IP address.Read more
