This document gives you an overview of the Apache world, including Apache Software Foundation projects such as the Apache web server and commercial and open source third party software. Apache is the most popular server on the Internet. New Apache users, especially those coming from a Windows background, are often unaware of the possibilities of Apache, its useful addons and, more in general, how everything works together. This document aims to show a general picture of such possibilities with a brief description of each one and pointers for further information. The information has been gathered from many sources, including projects' web pages, conference talks, mailing lists, Apache websites and my own hands−on experience. Full credit is given to these authors. Without them and their work, this document would not have been possible or necessary.

Infecting an .EXE is not much more difficult than infecting a
.COM. To do so, you must learn about a structure known as the EXE
header. Once you've picked this up, it's not so difficult and it
offers many more options than just a simple jump at the beginning
of the code.

Let's begin:

% The Header structure %
The information on EXE header structure is available from any
good DOS book, and even from some other H/P/V mags. Anyhow, I'll
include that information here for those who don't have those
sources to understand what I'm talking about...

This section is dedicated to those who would like to write a
virus, but don't have the knowledge to do so. First of all,
writing a virus is no big deal. It is an easy project, but one
which requires some basic programming skills, and the desire to
write a virus! If either of these is missing, writing a virus
would be tedious indeed!.

Well, if you meet these requisites, keep reading this article....

The long-awaited second edition is here! It's a complete rewrite of the first edition, considerably longer -- 455 pages instead of 320 -- and somewhat different in focus. It had better be, given how the Internet has changed since 1994. The best way to explain that is to note that the very last section added to the first edition was about this new-fangled thing called the Web...

Kalau ternyata blog ini tidaklah selengkap harapan Anda - malahan sangat jauh - tetaplah untuk tidak khawatir. Semuanya masih dalam proses perkembangan. Namanya juga blog baru. Pada waktunya nanti, e-book dari semua bidang komputer bakal diupload lewat sini. Oke? Oke? Oke, deh!

P.S. Semuanya akan indah pada waktunya - kata seorang teman saya.

The first things you should know about Common Gateway Interface (CGI) are what it is and why it is used. CGI is a standard whose specification defines a way for Web servers to communicate with external programs, and vice versa, so that the external program can generate HTML, images, or whatever, and have the server treat it the same as HTML, images, and so on not generated by an external program. The reason CGI is used is so you can generate dynamic content with the same ease that you generate static content. CGI is used because it is a very well defined and supported standard, and without CGI, dynamic content would have been impossible without proprietary server methods (now, there are alternatives to CGI that are becoming standard).

There are many useful applications of CGI programs. But, as with every other technology, CGI programs have their limits. Also, as with many other technologies, it is not always the best way to do things. For this reason, this chapter will go over what CGI programs can and cannot do, and what CGI based apps are good and bad for.

For comparison's sake, I use Java as the applet language...

The Evolution of the Enterprise Application

Is evolution really circular? Or, maybe it’s a never-ending spiral. This appears to be the case when we examine the history of the enterprise software application. In the early era of enterprise computing there were no trade-offs made with regard to an appropriate application model. There was only one option — a thin-client model leveraging centralized servers and delivering presentation to the user via a dumb terminal.

With the onset of the personal computer, the model changed, and power to the desktop had a strong evolutionary effect on the application model, moving it away from centralized computing toward a distributed model where individual computers hosted their own set of applications. This fat-client model pushed computation and presentation to the client. With advancement in graphics technologies, it became feasible to provide the user with a rich interactive presentation environment for applications. But these advancements did not come for free. Power to the desktop resulted in skyrocketing costs for deployment, management and maintenance of applications. Total cost of ownership for applications within the enterprise increased dramatically...
