Racial Profiling Technology
January 22nd, 2008
It has been known for sometime now that criminals leave traces of themselves at crime scenes whether it is in the form of blood, semen, hair or a scrape of skin. A unique genetic fingerprint is left behind that will establish the presence of one person with certainty. Thus is the known side of DNA Testing.
DNA however, has a lesser known aspect to it. DNA traces also leave clues of ancestry and appearance which can eventually be used as a foolproof police sketch. This could be far more helpful to the resolution of the crime than typically unreliable descriptions from eyewitnesses. The science should prove itself reliable especially if there are differences in opinion between the DNA markers.
More Than Just Video Conferencing
January 22nd, 2008
Standard video conferencing is associated with prohibitive costs. The introduction of web conferencing is an important development in business communication as it has enabled cost to decrease while application increases. More than ever, business can be done in the comfort of people’s homes courtesy of their desktop computer. Web conferencing has allowed users to do many things at a click of a button, doing away with the substantial cost entailed in traveling to do business. It has provided a suitable substitute to face-to-face meetings as users see, hear, text, chat, present and share information.
For all intents and purposes, people can meet through web conferencing whenever and wherever needed as long as the participants have access to an online PC or laptop. High costs associated with bandwidth are no longer a deterrent to communication due to the tremendous savings afforded by web conferencing.
A Closer Look on Human Natural Reflexes
January 21st, 2008
A reflex is a spontaneous and often unconscious action towards a triggering element. An itch triggers a person to scratch which is one way of warning that something is putting pressure on the skin such as a mosquito. Foreign invaders such as moulds, pollen and dust mites triggers coughing to help clear the mouth, throat or lung tissues. Sneezing is very similar to coughing except that it is directed through the nose.
Vomiting is usually caused by harmful substances that managed to reach the stomach or the upper segment of the small intestines. Tearing results when dust or debris irritates the eyes but the fluid causes the eyelids to overflow to wash away the irritant. These reflexes, although a bit annoying provides essential protection against toxins before they can cause further harm.
Yes to U.S. Players
January 21st, 2008
Not many industries have flourished on the internet as much as online casinos have. It seems that people took on online gambling naturally with as much enthusiasm as the original games in live casinos offer. But due to restrictions congress passed on U.S. players last year, the industry has been almost completely blocked off for U.S. players. Most sites do not accept deposits from U.S. players and most Americans can only enjoy this form of entertainment at physical destinations such as Las Vegas or Atlantic City. There are however sites that do accept American players and USA online casinos (available at usaonlinecasinos.org) does a great job of listing them and providing helpful reviews for each site. Not only do they feature extensive reviews for each site, they also list special bonuses new players can receive with their first deposit.
The Protective Layers of the SSH-2
January 20th, 2008
The SSH-2 or the revised Secure Shell protocol has a clean internal architecture made up of well-separated layers. The transport layer handles initial key exchange and server authentication and thereby sets up encryption, compression and integrity verification. The user authentication layer handles client authentication and provides various authentication methods. However, it should be noted that authentication is client-driven thus a password prompt may be initiated by an SSH client rather than the server.
The connection layer defines the concept of channels, channel requests and global requests using SSH services that are provided. SSH-2’s open architecture allows for substantial flexibility so that SSH can be used for a variety of purposes beyond the Secure Shell.
Communicating the IM Way
January 20th, 2008
Instant messaging or IM is considered by many as a better form of communication compared to email. This is due to the ability of IM to offer real-time communication while allowing for easy collaboration. IM is more similar to a genuine conversation as against the letter format of email. Peers are able to know when a user is busy, available or away from the computer. The difference however is negligible once a system allows offline messages or the sending of messages to people who are not logged on.
Additional features such as seeing the other party, using web-cams or direct conversation over the Internet for free helped in propagating IM’s popularity. Instantaneous and simultaneous communication is possible between several parties. Information is transmitted swiftly and efficiently and conversations can be saved for future reference.
