See http://www.gnu.org/philosophy/free-software-for-freedom.html for more explanation of the difference between the two movements.
The basic philosophy behind open source is very simple: When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, and people fix the bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.
There are many active Open Source Software projects but some may be thinking you get what you pay for, so if it's free there must be something wrong with it. Sometimes this is true but there are open source software projects providing stable, scalable applications. The key is to know where to look and what to look for when evaluating the stability and scalability.
Here are a few interesting facts and examples of Open Source projects:
Apache is the number one web server at nearly 62% of all installations. Second place was help by Microsoft at just under 27%. (Source: Netcraft)
GNU/Linux is the number two operating system at nearly 30% of all servers behind Microsoft operating system at nearly 50%. (Source: Netcraft)
Sendmail (a mail transport agent) sendmail has become one of the standards of the Internet's infrastructure (TCP/IP, Apache, sendmail).
BIND the Berkley Internet Naming Daemon responsible for mapping domain names to IP addresses ran on 95% of all public reverse DNS servers. (Source: Information Sciences Institute of the University of Southern California).
MySQL founded in 1995 by two open source veterans, Michael "Monty" Widenius and David Axmark, with the help of Allan Larsson and claims 4 million installations worldwide and 30,000 downloads of the software per day making MySQL by far the planet's most widely distributed open-source database. (Source: mySQL)
PHP is a widely used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML and as of May 2003 it was being used on 12,487,030 domains and 1,321,203 IP addresses. (Source: PHP)
Linux Operating System is over three years old and has grabbed 13.7 percent of the $50.9 billion market for server computers, and that figure is expected to jump to 25.2 percent in 2006, putting Linux in the No. 2 position. (Source: IDC)

project "Rems Zeitung" and his various solutions concerning usability on the editorial side and accessability on the user side.
After this soft start, Frank delivered a speech on the benefits the Ajax will bring in .8 and how it's used in his modules (pnForum, Multihook aso).
Third to speak was another core developer. Robert Gasch went deep into coding philosophy with his presentation titled "Arts & Crafts in Software Engeneering" - next to this he showed the advantages of Postnuke .8 over competetive systems and how the new technologies save up to 40% code in standard modules.
The next topic was the non-sponsored lunch at Subway's.
Newly energized Jazzie surprised the audience with his presentation on the soon to be released version 1.00 of the content module PagEd.
The last presentation of the day was another surprise: Albert Pérez Monfort and Toni Ginard Lladó of the Catalonian Ministry of Education showed us their project "Intraweb" a bundled Postnuke with several custom made and publicly available modules aiming at the Catalonian schools - over 100 schools use this package for their internal and external communication.

CERT Advisory CA-2002-09 Multiple Vulnerabilities in Microsoft IIS
(News)
-
Original release date: April 11, 2002
Last revised: --
Source: CERT/CC
A complete revision history can be found at the end of this file.
Systems Affected
* Microsoft IIS 4.0, 5.0, and 5.1
Overview
A variety of vulnerabilities exist in various versions of Microsoft
IIS. Some of these vulnerabilities may allow an intruder to execute
arbitrary code on vulnerable systems.
I. Description
There are a variety of vulnerabilities in Microsoft IIS. Many of these
vulnerabilities are buffer overflows that could permit an intruder to
execute arbitrary code on vulnerable systems.
We strongly encourage all sites running IIS to read Microsoft's
advisory on these and other vulnerabilities and take appropriate
action as soon as practical. Microsoft's bulletin is available at
http://www.microsoft.com/technet/security/bulletin/MS02-018.asp
Additional information about these vulnerabilities is available at
http://www.kb.cert.org/vuls
VU#363715 CAN-2002-0071 Microsoft Internet Information Server (IIS)
vulnerable to heap overflow during processing of crafted
".htr" request by "ISM.DLL" ISAPI filter
VU#883091 CAN-2002-0074 Microsoft Internet Information Server (IIS)
contains cross-site scripting vulnerability in IIS Help
Files search facility
VU#886699 CAN-2002-0148 Microsoft Internet Information Server (IIS)
contains cross-site scripting vulnerability in HTTP error
page results
VU#520707 CAN-2002-0075 Microsoft Internet Information Server (IIS)
contains cross-site scripting vulnerability in redirect
response messages
VU#412203 CAN-2002-0073 Microsoft Internet Information Server (IIS)
vulnerable to DoS via malformed FTP connection status
request
VU#454091 CAN-2002-0150 Microsoft Internet Information Server (IIS)
vulnerable to buffer overflow via inaccurate checking of
delimiters in HTTP header fields
VU#721963 CAN-2002-0149 Microsoft Internet Information Server (IIS)
buffer overflow in server-side includes (SSI) containing
long invalid file name
VU#521059 CAN-2002-0072 Microsoft Internet Information Server (IIS)
vulnerable to DoS when URL request exceeds maximum
allowed length
VU#610291 CAN-2002-0079 Microsoft Internet Information Server (IIS)
buffer overflow in chunked encoding transfer mechanism
VU#669779 CAN-2002-0147 Microsoft Internet Information Server (IIS)
buffer overflow in chunked encoding transfer mechanism
II. Impact
For many of the vulnerabilities, an intruder could execute arbitrary
code with privileges that vary according to which version of IIS is
running. In general, IIS 4.0 permits an intruder to execute code with
complete administrative privileges, while IIS 5.0 and 5.1 permit an
intruder to execute code with the privileges of the IWAM_computername
account.
III. Solution
Microsoft Corporation has released Microsoft Security Bulletin
MS02-018, which announces the availability of a cumulative patch to
address a variety of problems. We strongly encourage you to read this
bulletin and take the appropriate corrective measures. MS02-018 is
available at
http://www.microsoft.com/technet/security/bulletin/MS02-018.asp
In addition to applying the patch, or until it can be applied, we
recommend the following actions:
* Use the IIS Lockdown tool and URLScan to eliminate or reduce the
impact of some of these vulnerabilites; they may also eliminate or
reduce other vulnerabilities that have not yet been discovered.
The IIS Lockdown tool can also be used to disable ASP if it's not
needed. More information about the IIS Lockdown tool and URLScan
can be found at
http://www.microsoft.com/technet/security/tools/locktool.asp
http://www.microsoft.com/technet/security/URLScan.asp
* As Microsoft has recommended for quite some time, disable the HTR
ISAPI extension unless it is absolutely required.
* Disable anonymous FTP unless it is required.
* Don't give login credentials on IIS servers to untrusted users.
