FlightGear Flight Simulator
This is a seriously cool Flight Simulator! There are binaries for various Operating Systems (including Windows) and map data for the entire world. If you order them, the whole set comes on 3 DVD's for $40. I'm thinking a Live-CD with FlightGear module might be kind of cool. Oh, and imagine flying it on the Access Grid...
From the "Introduction" page:
The FlightGear flight simulator project is an open-source, multi-platform, cooperative flight simulator development project. Source code for the entire project is available and licensed under the GNU General Public License.
The goal of the FlightGear project is to create a sophisticated flight simulator framework for use in research or academic environments, for the development and pursuit of other interesting flight simulation ideas, and as an end-user application. We are developing a sophisticated, open simulation framework that can be expanded and improved upon by anyone interested in contributing.
Wireless Attacks and Penetration Testing
SecurityFocus HOME Infocus: Wireless Attacks and Penetration Testing (part 1 of 3)
Three part series on penetration testing for wireless networks. The first installment details many common styles of attacks against wireless networks, introduces WEP key-cracking, and discusses some recent developments in wireless security.
Wireless Attacks and Penetration Testing (part 2 of 3)
In this installment, the author focuses on a cracker attempting to penetrate your network and hack one of the servers held therein.
Wireless Attacks and Penetration Testing (part 3 of 3)
In this final part, the author looks at ways to mitigate the risks outlined in the previous parts of the article and spends a bit of time looking at some proposed solutions currently in front of the IETF.

Editing the Registry for "other" Users
From an account with Administrator level access
1) Click Start, Run and enter REGEDIT
2) In Regedit, highlight the HKEY_USERS key and go to File, Load Hive.
3) Use the File Open dialog to go to the Documents and Settings\ folder, where is the account you wish to modify.
4) Highlight the NTUSER.DAT file in this folder (usually a hidden file) and select Open.
5) You'll be prompted to enter a "Key name". You can use whatever you wish, but I use the User's logon name.
6) You can now expand the Hive you just loaded and make any needed changes.
7) When finished, highlight this Hive again and go to File, Unload Hive.
NOTE: You MUST unload the Hive prior to logging on to the users account. Otherwise XP may have trouble loading the user's profile.

NCSA - Mitch Kutzko's page
Mitch Kutzko
Mitch is the author/maintainer of the Multicast Beacon client and server software which is used for monitoring unicast & multicast connections. It is best known in it's role monitoring Access Grid nodes around the world, but it's also useful for things like monitoring WAN links.
I blogged this because he's got an interesting collection of links that I'd like to go spelunking through sometime in the future.

Network Security Toolkit - BootCD
NST is a bootable ISO CD is based on Red Hat Linux 9. The toolkit was designed to provide easy access to best-of-breed Open Source Network Security Applications and should run on most x86 platforms.
The main intent of developing this toolkit was to provide the network security administrator with a comprehensive set of Open Source Network Security Tools. The majority of tools published in the article: Top 75 Security Tools by insecure.org are available in the toolkit.
NST can transform most x86 systems (Pentium II and above) into a system designed for network traffic analysis, intrusion detection, network packet generation, wireless network monitoring, a virtual system service server, or a sophisticated network/host scanner. This can all be done without disturbing or modifying any underlying sub-system disk. NST can be up and running on a typical x86 notebook in less than a minute by just rebooting with the NST ISO CD. The notebook's hard disk will not be altered in any way.

WORDCOUNT / Tracking the Way We Use Language
WORDCOUNT / Tracking the Way We Use Language /
WordCount™ is an artistic experiment in the way we use language. It presents the 86,800 most frequently used English words, ranked in order of commonality. Each word is scaled to reflect its frequency relative to the words that precede and follow it, giving a visual barometer of relevance. The larger the word, the more we use it. The smaller the word, the more uncommon it is.
- beef = 5265
- steak = 11,620
- chicken = 4162
- fish = 928
Looks like the Beef Industry Council needs to do some marketing...

Creating ISOs from CDs
Creating ISOs from CDs - TreehouseTechnologies
How do we get an ISO file when we only have the burned CD?
# mount /dev/cdrom /mnt/cdrom
# df
(By mounting the CD, we can get the true block count of the ISO image. Make a note of the "1K-blocks" number for the CD.)
# umount
# dd if=/dev/cdrom of=/tmp/aniso.iso bs=1k count=[insert 1k block count here]
By specifying the exact size of the image, we prevent trying to read the overburned sectors and end up with an exact ISO image, that is the same size and has the same MD5 sum as the original.

When it comes to network monitoring/graphing, Tobi Oetiker's RRDTool does it best. It gives you the ability to put data into a database, then represent that data on a graph as you see fit.
One drawback to RRDTool, is that by itself it is not a complete package for users wanting to graph their own networks. This is where cacti's job comes in. Cacti brings the power of RRDTool to a friendly web interface making it easy to graph anything using RRDTool.
Other frontends have been created in the past that simply emulate MRTG using RRDTool as a backend. Cacti, on the other hand exploits RRDTool's full potential; utilizing Round Robin Archives, CDEF's, Data Sources, and Graphs.
Get more details about cacti.

Alternative Medicine
A woman went to the Doctor's office, where she was seen by one of the new doctors, but after about 4 minutes in the examination room, she burst out, screaming as she ran down the hall.
An older doctor stopped her and asked what the problem was, and she told him her story.
After listening, he had her sit down and told her to go relax in another room.
The older doctor marched down hallway to the back where the first doctor was and demanded, 'What's the matter with you? Mrs. Bloggs is 63 years old, she has four grown children and seven grandchildren, and you told her she was pregnant?'
The new doctor continued to write on his clipboard and without looking up said, 'Does she still have the hiccups?'
