Audacity is an open source software for manipulating audio. The following are few important features of audacity:
- Record live audio
- Playback recorded audio/sound files
- Edit sound files by cut, copy & paste.
- Convert audio from one format to another
Apart from Linux you can also install Audacity on Windows and Mac OS X.
This article explains few essentials features of audacity with screenshots.
Most of us might not be aware that there is a Windows Core version, which has only command-line without any GUI.
This core version relatively provides high level of security, as all GUI interface are removed, which also increases the performance of the system.
This might be helpful if you are running Windows server.
Hyper-V Integration Services (IS) provides performance enhancements to a child partition (i.e. Guest machines, Virtual machines).
It provides better user interaction between child and parent partitions while accessing virtual machines.
It provides drivers to all virtual components that are installed in the virtual machine. For example, Network Cards, IDE/SCSI Drives, Human interface devices, etc.
Use import and export feature, when you want to create a new virtual machine with the same configuration of an existing machine in Hyper-V.
The exported virtual machine files are saved in the server, and can be reused as many time as you want to create new VM.
Machine generates new SID while importing from the machine files. This future will help us to clone N number of virtual machine without any conflicts in same network.
Synergy is an open source network utility which can be used to share one keyboard and mouse with multiple systems.
Synergy utility works on client-server model.
The system whose keyboard and mouse you want to share, runs the synergy server service (synergys), and all the other systems runs the synergy client service (synergyc) to connect to server.
As a Linux sysadmin, for some reason, if you are thrown into a virtualization environment that also has Windows, you should be aware that there two ways to create VM in a Hyper-V server.
You can create VM either using the powershell commands from the Hyper-V server, or using a GUI interface from Hyper-V manager, which is a Hyper-V role enabled windows server, as explained in this tutorial.
If you are thrown into a situation where someone already installed a Windows Hyper-V server for virtualization, it is helpful to understand how to perform certain basic sysadmin operations like creating a new VM.
Once you’ve installed the Hyper-V server free stand-alone version, you can create a new VM using one of the following methods:
Sometimes as a Linux Sysadmin, you might end-up in a situation where you may have to manage some Windows server as part of your virtualization strategy.
In those situations, it is good to know some fundamentals of how to manage Hyper-V virtualization on Windows.
If you like to manage the Hyper-V server from a GUI, enable the Hyper-V role on a separate Windows Server 2008 or 2012, as explained in this tutorial.
