Computer Graphics programs in C++
The term computer graphics includes almost everything on computers that is not text or sound. Today almost every computer can do some graphics, and people have even come to expect to control their computer through icons and pictures rather than just by typing. Here in our lab at the Program of Computer Graphics, we think of computer graphics as drawing pictures on computers, also called rendering. The pictures can be photographs, drawings, movies, or simulations -- pictures of things which do not yet exist and maybe could never exist. Or they may be pictures from places...

Packet garbage and analysis using Wireshark
On the Internet, packet filtering is the process of passing or blocking packets at a network interface based on source and destination addresses, ports, or protocols. The process is used in conjunction with packet mangling and Network Address Translation (NAT). Packet filtering is often part of a firewall program for protecting a local network from unwanted intrusion. In a software firewall, packet filtering is done by a program called a packet filter. The packet filter examines the header of each packet based on a specific set of rules, and on that basis, decides...

Optimism Vs Pessimism
Is Your Glass Half Full or Half Empty?Are you a glass half full or a glass half empty kind of person? Does it really make a difference? I think it makes a huge difference in the quality of your life. Both optimists and pessimists contribute to our society. The optimist invents the airplane and the pessimist the parachute. Two men look out through the same bars: One sees the mud, & one the stars.Optimism can lead to accomplishment. If you think something is possible, you will generally work harder to achieve it. Believing...
