How can you tell if a technology has reached critical mass?
Easy: you look at how much damage it’s causing. Pretty
much every human invention is neutral in itself; any benefits
(or drawbacks) come from the way it’s used: atomic
energy can be used to power a city or destroy it; cars make it travel
over distances that were unthinkable just a hundred years ago
possible, and are happily destroying our planet with their polluting
The Little Black Book of Computer Viruses has seen five good years in print. In those five years it has opened a door to seriously ask the question whether it is better to make technical information about computer viruses known or not.
When I wrote it, it was largely an experiment. I had no idea what would happen. Would people take the viruses it contained and rewrite them to make all kinds of horrificly destructive viruses? Or
would they by and large be used responsibly?
This leads me to my point. Often, the article
ideas submitted to us at php|a deal with
aspects of PHP development that we know little
about. As technical editors, though, it is
our job to ensure that the material presented
here is as accurate as possible, which forces us
to (as much as possible) fully understand and
grasp the technology being discussed. This
presents incredible opportunities for learning
The CompTIA Security+ certification designates knowledgeable professionals in the field of security, one of the fastest-growing fields in IT. Security threats are increasing in number and severity, and the gap between the need for security professionals and qualified IT personnel is the largest of any IT specialty, according to a 2008 CompTIA study. Even in a troubled economy, most businesses plan to maintain or increase their investment in security.
Subnetting is a complicated topic that has confused students for a very long time. However, subnetting is an important topic for many different certifications with various vendors, including Cisco. In the real world environment, people are used to just punching in the numbers in many of the free subnet calculators that are readily available on the internet. For exam purposes, you still have to do this in a very fast manner since many exams are time-based and you don’t have the luxury of spending those precious minutes on any single question.

What does the wired portion of a next generation wireless network look like? The better
question is this—what does the wired portion of a next generation wireless network look
like at specific points in time: one year, three years, seven years from now, and so on
into the future? That question is hard to answer because migration to next generation
networks is an evolutionary process.
Microsoft has once again come up with a new suite of certifications. So, what are these all about and why is
there a new generation of credentials?
One of the problems today is that there are an abundance of credentials in the IT world, making it increasingly
difficult for managers to understand which certification best meets the needs of their department and organization.

Each section ends with a quiz and series of questions (and answers), so you can test your knowledge of each topic. The book also includes useful sections on sample installations and a nice discussion of sockets. As an added...
Are you ready for Microsoft SQL Server 2008? The truth is, many of us are still coming to grips with the great

When I first went to the CCIE lab, there weren't very many books available and little was known about the CCIE lab,
except that the labs had a reputation for being extremely difficult. Any regular reader of the Cisco mailing lists at
groupstudy.com will often see questions posed to the various lists about the best way to prepare for the CCIE lab
such as: "What are the best strategies to use?" "What is the lab like?" "Where should I go to take the lab?" and many
more. This Tutorial answers these questions within the bounds of Cisco's strong nondisclosure agreement. This paper
will discuss in...

The purpose of this paper is to resolve any lingering questions you may have about ping and to take your understanding to the next level. If you do not happen to be a programmer, please do not be frightened off! I am not going to tell you how to write your own version of ping; trust me....
Data networks developed as a result of business applications that were written for microcomputers. At that
time microcomputers were not connected as mainframe computer terminals were, so there was no efficient
way of sharing data among multiple microcomputers. It became apparent that sharing data through the use of
floppy disks was not an efficient or cost-effective manner in which to operate businesses.
