Cutting Edge Secrets To Dominate The Rankings On Google And Get Massive Traffic

Posted on Posted in website

Knowing how to get good rankings on Google is a really important skill that will significantly benefit your business. The primary reason for this is that it allows you to benefit from highly qualified search engine traffic which is the lifeblood of your business.

Ever since the rise of Google getting quality inbound links has become extremely important as this is the major factor for determining how well your site ranks in the eyes of the search engines. This can also be an extreme challenge to get right.

The best way to do this is to build a quality website that people want to link to. If you look at popular sites like MySpace they do not have to ask as people will naturally link to them since they are a good content website.

The most important type of link to get is a one way one. Many years ago people would get reciprocal ones, but with the abuse that took place these have become ineffective as search engines have become a lot more sophisticated.

The best way to get good quality anchor links is to have the keywords that you are targeting on the web page being used as the linking text. This will give those pages a significant boost. I suggest that you use popular keyword research tools like Wordtracker and Keyword Discovery to perform this important research.

Finally, you can jump start your linking campaign by submitting to directories and writing articles and submitting them to the major article directories including a link to your website in the bio. …

OpenGL Terrain Generation – An Introduction

I have always been interested in computer graphics and their applications. Data representation and visualization is one of the main areas of HCI (Human Computer Interaction), and the better you make the interaction between a machine and a human, the more productivity will be generated by both the human and the machine. I had some experience with OpenGL during my undergraduate studies while attending the California Polytechnic University. Unfortunately, I never got a chance to pursue the more advanced features of the OpenGL library, given my time and work responsibilities.

You can find more about OpenGL at http://www.opengl.org . There are also a bunch of good literature available on the topic of Computer Graphics and OpenGL that you can refer for further advances. Please check the Background / Reference section for a list of some reference material that I have used, in general, for computer graphics.

The following project is a very simple example demonstrating how to generate a terrain based on a bitmap file. The objective of the project is to generate a three dimensional terrain based on some data file. Please note, that this could have been any data file, but for the purpose of our example, we are going to be using a 32×32 dimensional bitmap file. We could have easily used a text file, and defined logic for each word or letter to represent it graphically.

The project also contains a good Windows framework that can be used for your other OpenGL applications. The current project allows you to rotate the camera using your mouse.

Once again, this is a simple approach to terrain generation, which can be a very difficult task in complex environments.

Background / Reference
Since Computer Graphics is kind of an advanced topic, it is necessary to have at least some king of understanding and exposure to the concepts and theories in the field. However, this does not mean that you will not be able to use the following code or understand it. I have made it as simple as possible, and hopefully, it will give you a good start, or some additional source of information that you can use for your projects. Also, please note that you will need to have a good understanding of C / C ++ programming.

Some books I have used for learning Computer Graphics and OpenGL programming:

Books I used while attending the California Polytechnic University:
OpenGL Programming Guide, or better know as the Red Book.
Computer Graphics Using OpenGL, 2nd Edition.
Books I used while attending the California Lutheran University:
OpenGL: A Premier, 2nd Edition.
Interactive Computer Graphics: A Top-Down Approach Using OpenGL, 4th Edition.

What is a Terrain?

Some background information on a terrain and their uses in a game application: A terrain in an environment is one of the most critical components in the scene that is being rendered. It could easily be the …

Privacy Issues Surrounding Biometric Technology

Posted on Posted in technology

The terrorist attacks on the World Trade Center have provoked in-depth discussion and study of existing security measures, their deficiencies, and how to enhance security to prevent similar terrorist attacks from occurring in the future. Biometric technology has risen to the top of the list as a possible solution. The government is not the only entity exploring biometric security systems. The financial services industry see biometrics as a way to curb identity theft. Biometrics are intrinsic physical characteristics used to identify individuals. The most commonly used biometric is fingerprints but others include, handprints, facial features, iris & retinal scans, and voice recognition.

Soon after 9/11 there were calls for the issuance of national ID cards containing biometric information on an RFID chip implanted on the card. The argument is that national ID cards will increase security by identifying individuals with their unique fingerprints which are much more difficult to counterfeit than standard photo ID cards. There is also a movement toward biometric passports. It looks like biometric passports are coming soon. National ID cards may follow.

Biometric identification is nothing new. Humans have been identifying other humans biometrically since the beginning of time. You recognize people you know by their facial features, their voice, and other biometric features. What’s new is introducing technology into the mix that compares a given biometric with a stored database of biometrics to verify the identity of an individual. An individual place their finger on a fingerprint scanner and the image is compared with the database to verify the person’s identity. Promising as it is, biometric technology has not been without hiccups but biometrics are advancing quickly and becoming more and more prevalent in security systems.

Fingerprints are the most commonly used biometric identifiers. The National Institute of Standards and Technology (NIST) conducted a study that showed single fingerprint biometric systems had a 98.6 percent accuracy rate. The accuracy rate rose to 99.6 percent when 2 fingerprints were used and an almost perfect 99.9 percent when 4 or more fingerprints were used. The study results show that biometric identification is nearly perfect which is not surprising given the uniqueness of human fingerprints.

The US-VISIT program, which is an acronym for United States Visitor & Immigrant Status Indicator Technology, currently requires foreign visitors to the US to present a biometric passport containing 2 fingerprints and a digital photo for identification purposes before being granted admission to the U.S. Of course the biometrics are compared against a vast network of government databases full of known and suspected terrorists and other criminals.

On the surface biometric technology may sound like a panacea but it’s use has raised significant privacy concerns that need to be addressed. Here are six major privacy concerns: storage, vulnerability, confidence, authenticity, linking, and ubiquity.

Critics wonder how the data will be stored and how vulnerable it will be to theft or abuse. Confidence issues center around the implications of false positives and false negatives. Can the biometric data be used to link to other …
