Multiple Operating System

Yes, you can have multiple operating systems on one pc . BUT, i suggest you to not to do this. I mean do not install multiple OS (Ubuntu + Windows, etc.). Because their way of handling MBR and other things related to HDD (hard disk) like format system (fat, ntfs, ext1-2-3-4, etc) is different. ubuntu undestands the windows file-system. But, windows dose not understands ubuntu file-system and by chance MS windows make any mistake to ubuntu file-system then MBR (master boot record) of you hard disk crashes. Than, you will have to run here and there to get back your all data on hard disk. because total partition of your system will be deleted.

That happened to me most of times having MS windows+Ubuntu.

But, Even than if you want to try multi boot system having different file systems, best of luck. Just Go to this link given below

It doesn't hold some feaures back for a payware version.
Its source code is available for anyone to review.
Its website and forums have no third-party ads or analytics.

Simplicity
Chrome's browser window is streamlined, clean and simple.
Chrome also includes features that are designed for efficiency and ease of use. For example, you can search and navigate from the same box, and arrange tabs however you wish — quickly and easily.

How to Choose an Open Source Library

Having a lot of open source to choose from is definitely a good thing. However, the downside is that you have to do some actual work to figure out which is best for your project. So here's are some rules of thumb on how to quickly evaluate and pick an open source library. Specific emphasis on "library" since our intent is to incorporate it into our own work as opposed to simple usage.

1. Usage - Google's PageRank algortithm ranks web pages based on the quantity and quality of other web pages linking to it. It's similar to the rule of thumb of looking at citations to discern the quality of an academic paper. In similar spirit an open source library's quality can be discerned from the number and quality of other open and closed source projects that use it. For example, the Hibernate project has a ton of projects that not only use it but provide tools to support it.
2. Extensibility - An essential quality of most popular projects is the presence of a well defined mechanism for extension. Look for this in the library your are evaluating, the lack of this quality can put you in a bind that's extremely difficult to extricate oneself from. For example, Eclipse and JEdit have well defined plugin architectures that make it workable for multiple contributors to enhance the platform without stepping on one another.
