nature
The word nature is derived from the Latin word natura, or "the course of things, natural character." Natura was a Latin translation of the Greek word physis , which originally related to the intrinsic characteristics that plants, animals, and other features of the world develop of their own accord. This is shown in the first written use of word, in connection with a plant. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word by pre-Socratic philosophers, and has steadily gained currency ever since. This usage was confirmed during the advent of modern scientific method in the last several centuries.

blogging helps in gaining
Now i got tracked in the field of blogging.. Found lots of new opportunities in blogging.. Most of them have different opinion on blogging.Some think as just a time pass, others suggest as waste of time in hanging over blogging.. Definitely not so. I found it as an way of posting our own views and concepts that we learn. They encourage our views by paying for our posts in blogs.
I found payperpost an interesting site. They link right advertisers with right bloggers. Both of them gain benefit through blogging.Even i am going to be paid for my blogs and will have new opportunity to advertise and earn few dollars from that.
I found blogging not only for earning money but also gaining power of writing posts of our unique ideas. This helps in acquiring knowledge and power of getting new ideas and views on all topics. It allows us to follow some basic rules through word of mouth ethics... Philosophy of blogging can be known from this ... Blogging helps us in many ways.. Advertisers found easy by paying bloggers to share their works and loads.. Best kind of organisation is seen and learned through blogging.
Blogging is nothing but learning business admistration over application of blogging, from my point of view.
Check out and benefit from blogging, Payperpost.

OVERVIEW OF THE SYSTEM:
The P2P VOIP architecture decentralizes the Call Processing Server by having a modified SIP client and server installed on each user's computer and by making intelligent use of Callee's SMTP server-log to obtain location information to initiate a VOIP call. Caller consults the Callee's SMTP server to obtain plausible IP addresses of the Callee. Callee's location is probed heuristically using IP addresses and timestamps obtained from SMTP server logs. Call parameters are then extracted from the SIP server running on the Callee's computer.
The modified SIP client on the Caller's side contacts Callee's SMTP server and subsequently contacts the Callee's SIP and RTP to locate connection parameters, and finally initiate a call. This architecture essentially eliminates the need of a VOIP provider. Our approach works with an assumption that users use their computers to check e-mail periodically; and we can heuristically gather information about the user's location by intelligently traversing the SMTP server-log. Please note here that the called party is uniquely identified by his or her Email address. SMTP logs give location information (IP, Time stamps, etc.); and finally, a call is initiated directly between the peers using SIP handshaking and RTP/RTCP based communication
