OpenNMS is a Java based network management tool. OpenNMS provides polling, data collection and event notification.
It is supported for Linux systems and have a graphical monitoring feature allowing network administrators to view things like bandwidth utilization, system downtime and security events.
OpenNMS can be customized to provide monitoring for switches, routers, servers, and other network equipment. It can also be used to keep track of assets.
Windows 7 vs Linux
Now that Windows has come out with Windows 7 (don't they have a cool name for this one?) the debate is on again that Linux is dead. What do you think?
I couldn't disagree more. Though I have not had the opportunity to work with Windows 7 yet, I have several reasons why I don't think Linux will ever die at the hands of any version of Windows.
1. Window has no plans of going open source. As long as this is true, you will never be able to truly customize Windows to fit your needs.
2. A quick check on Newegg proves that Windows 7 promises to sport a hefty price tag, just like all the other Microsoft products.
3. Windows 7 isn't a server OS, so it won't compete with Linux in Linux's largest market.
4. As long as Windows retains the largest market share, it will also retain the largest number of viruses and other attacks.
I think the summary answer to the question is that Windows 7 and Linux don't necessarily compete head to head. Both systems have niche markets and I don't think either system will penetrate the other's niche. Windows server edition is a greater threat to Linux than Windows 7.
Is there room for both Windows and Linux? And what about Apple?
Yes, and the answer goes back to niche markets. Windows is and probably will remain the primary business OS because of it's user friendliness and price point.
Apple has a market in the graphic design and multi media market.
Linux has the open source crowd. As long as all those different types of needs exist there will be room for all 3 operating systems.
Have you looked at Windows 7 yet? What are some of the new features that might make you upgrade your system to it?
I have not had an opportunity to work with 7 yet, but the advertised feature that jumps out at me right away is speed. I would definitely consider upgrading from Vista for a snappier OS.
The other advertised feature that I find very appealing is improved boot times. Waiting 2 or more minutes for Vista to finally load gets pretty old. Microsoft has a long way to go to keep up with distros like Xanros Presto! which claim boot times for a partial OS in just seconds.

What is Andriod
Android is Google's open source, Linux based, mobile OS for mobile phones. I most definitely believe there is a future in Android. It offers many of the same features that the Iphone offers, but on a completely open source platform. In addition Android is both carrier neutral and hardware neutral, allowing more vendors to utilize the technology and more customers the ability to purchase the technology.
For those who like a challenge - who is Alex Rubin and what does he have to do with android?
I'm not totally sure about this one, but as best I can tell, Alex Rubin is Andy Rubin's dog. Andy Rubin is a developer on the Android project, and currently the Director of Mobile Platforms at Google.

Linux Kernel Numbering
The Linux kernel numbering system has changed a bit over the years. Originally, Linux kernels were numbered based on whether they are stable release or not. Even numbers were stable releases and odd numbers were more development based. The second number in the string is the one that indicates a stable release. For example, 2.6.31.1 is the current sable release. 2.5.X.X was a developmental release that 2.6.X.X was based on. This numbering system was officially scrapped with the 2.6.X.X release.
Now development has started on the 2.6.X.X kernel, and Linus Torvalds has indicated that he does not intend to go to a 2.7 release to denote the development release. Instead development is being done on the minor releases. A minor release is denoted by the third number in the 2.6.X.X format. The forth number of the format indicates bug fixes, security patches, and other corrections.
In the current numbering scheme, a developmental release is indicated by the letters "rc" followed by a number. RC stands for release candidate, indicated that it is not ready for a production environment.

AppArmor
AppArmor is security software for Linux. AppArmor works by isolating applications so weaknesses in on application can not be exploited to affect the entire system. In AppArmor, each application is given a profile. The profile can then be customized to define which system resources can be accessed by that application.
Another cool tool that can be installed on Linux, and my personal favorite is Wine. Wine is an application that allows you to run most Windows applications on Linux. Wine is an open source application that is developed by an all volunteer force.

Open Source and Making Money
How do companies like RedHat make money?
Many open source companies like RedHat make their money supporting their products in several different ways. Some of those ways include 24/7 tech support and training on their products. Many companies also publish books to train folks on their products.
What makes open source open?
Open source is open because the source code is available to the public. Developers can find and edit to the source code. This allows developers to alter the code to fit their specific needs and fix bugs they find in the code.
Why didn't Bill Gates consider going open source?
Why Bill Gates didn't consider going open source is a tough question to answer. In his own words, open source creates a license "so that nobody can ever improve the software,".
Many other would argue that by controlling the source code, Gates can in many ways control who can develop software to run on Windows and therefore maintain a monopoly on the money generated by the PC market.

The Cathedral and the Bazaar
Research and find out what you can about "Cathedral and the Bizarre". Tell me in your own words what it is and why it might be important.
"The Cathedral and the Bazaar" is a book written by Eric S. Raymond. It makes a comparison between the traditional pay software development and open source. He has compared the open source model to a bazaar and the traditional software development model to a cathedral.
The cathedral model involves a team of developers, most likely in the same location, with a leadership team and a defined goal.
The bazaar model involves somewhat of an ad hoc team of folks, most times connected only by the internet, modifying a project to fit their individual needs.
It is important because these two methods of development are finding themselves in close competition more and more frequently. As Linux students, it is very important for us to understand the bazaar method, as that is how most Linux is developed. A programmer writes some codes, then posts the code and other developers are free to alter the code as they see fit for their particular needs.
