I am interested in virtualization related projects. However there seems to be plenty of options in this field. Which project should i start working on given the above choices. I want to work on on of these projects going forward. I am familiar with the basics of virtualization methods available and basic interfaces. Have been using VirtualBox for more than 3 years now.

First, ask yourself what type of code you want to contribute. If it is more on the binary-translation side, your best choice is QEmu since it does all the core work for KVM. KVM on the other hand, is an architecture that sits upon QEmu and leverages the Linux kernel's scheduler. So if IPC, process management, signals etc are your thing, jump into KVM. i would suggest that you study the architectures of these hypervisors and then decide what you want to get into.
This was a specific example. Virtualization is much more than hypervisors. Look into OpenStack. It is to virtualization what Android is to smartphones.
Another interesting thing to look into, to begin coding would be libvirt. It is the underlying library that powers most of hypervisor-agnostic virtualization frameworks and orchestration tools.

as the final project for a programming course I took I've made a small tool which deals with databases issues. It works and I think it could be useful to others, so I'd like to put the code on the net to see if it actually is.
I'm aware of various source code hosts such as GitHub or Google Code, however they seem more oriented towards group development and I'm not sure if they're good for individual complete projects as well. I'm not saying I'm opposed to collaboration, but those platforms just seem a bit too much for something so simple.
Does anyone have any idea on how I should share the code?
Github would be fine - just because git allows multiple developers on a project doesn't mean it is required.
Most of the complexity is there if you need it but you do not have to ever visit those screens. The last time I looked at the network view for my more complex projects was a long time ago!

I have recently study on how to implement WebRTC MCU software on the server. I find an open source project called licode, but it is difficult for me to understand its source code. Can you recommmend some articles or documents about explaining the source code of licode, or there is another open source project you can recommend about implementing WebRTC MCU?
Janus is what you are looking for. It is the new cool kid on the block and I've found it to be really easy to understand since it doesn't make assumptions in the signaling plane or the features you'll use in your gateway.
It comes with a core that acts as a central hub for browser connections and then implements all its features with plugins. For instance here you have the Video MCU plugin code:
https://github.com/meetecho/janus-gateway/blob/master/plugins/janus_videoroom.c
As you can see it is programmed in C and comes with a JS API and clear code samples. Give it a go, I think it is ideal for a project study compared to already bloated multi-stack solutions (Licode, Jitsi Videobridge, etc)
Hope it helps!

I'm currently about to begin work on a project and I'm wondering which library is the best to use.
The project is to create a simulation of a particular scenario. It's main requirements are:
Animation on various parts / objects
User input for some variable, including the constructor parameters of some objects.
Collision detection
Flood algorithm.
Images will be required and the 'pattern' aspect of fabric would be perfect for a couple of objects
I'm attempting to model the Macondo well disaster.
I recently discovered Fabric js and was excited, very excited at the prospect of being able to use objects. I then looked a bit harder and found many other libraries that are available.
I'd like to ask what the benefits of using Fabric js are over those of the alternative libraries. From what I've described, would Fabric be able to cater to all the requirements and would an alternative framework be a better solution?
Thanks for any help.

We've been using OCS-NG to gather our computer inventory for the past 2 years. About 6 months ago, AVG Antivirus started picking up on the agent it uses to gather computer information as a "potentially harmful program". We've placed that in our ignore list, but the agent no longer appears to be updating our database. After much consideration and frustration trying to diagnose, I've decided to move away from OCS-NG as well as GLPI (with which it interfaces nicely).
I'm looking for a replacement for both of these applications, but primarily OCS-NG. My requirements are:
Open Source (preferably free)
Windows/Linux inventory agents
I would like it if the system was able to be integrated with a helpdesk system such as OTRS or the like.
Thanks
On this moment there is no 'canned' asset discovery solution which has an out-of-the-box integration with OTRS.
However, OTRS is able to import CI data from CSV files. Also, we're hard at work cooking up a new SOAP/REST/JSON interface.
We're planning on integrating with asset discovery solutions, and would be open for people wanting to help with us on creating and testing the integration, and/or help from anyone working on FOSS asset discovery projects.

I'm looking to create a program that will burn an audio CD. Before diving in I was hoping to see a selection of libraries that will make writing the code to burn the audio easy to write. I don't care much about language but something that is cross OS would be nice. (Specifically Windows and linux).
So far the only library that I see is PrimoBurn, but I can't seem to get their C++ version to compile.
So what do you guys use?
cdrecord runs on both Windows and Linux (Mac as well). Call it through a system call.
