From what I can gather, the linux system is used on-board to manage the in flight entertainment system. This system feeds music, Dish Network TV, flight information, and games to each screen during the flight. One of the free games even allows you to play a trivia game against the other passengers. It even appears to have a simple transaction processing system for purchasing several items. I am glad to know Linux is alive and well at 30,000 feet!

ABSTRACT:
The science of cryptography has existed in one form or another for centuries. There are many common implementations of cryptography in use today such as the HTTPS protocol on the Internet. All forms of data encryption and cryptography require a key in some form or another for use in encoding and decoding data. The inherent problem with any form of cryptography is the possibility that the key may be intercepted by an eavesdropper. In a recent breakthrough a technique called quantum cryptography has been shown to possibly guarantee the privacy of an encryption key during distribution using quantum mechanics. As quantum cryptography continues to evolve, it has potential to become the de facto standard for the transportation of confidential information.

So I went on a quest to see if there was an easy way to use POSIX (Portable Operating System based on Unix) commands in the Windows Command Prompt.

The answer… Cygwin!!

Cygwin is about the niftiest thing since sliced bread. In a nutshell, it is a collection of a buch of common GNU posix applications ported and compiled to run on Windows. And best of all, it is a sinch to install.

Steps to install Cygwin:

1. Download and run the installer
2. Select Download Source

   

3. Select Root Install Directory

   

4. Select Local Package Directory

   

5. Select Connection & Download Mirror
6. Select Packages (Toggle the View to “Full”). Be sure to go over the list and add any extra packages you would like to download.

   
   The installer will then download and install your selected packages.

Steps to make Cygwin commands available in the Windows Command Prompt:

1. Hold ALT and Double-Click “My Computer” and select the “Advanced” tab

   

2. Click the “Environment Variables” button
3. Under the “System variables” section, double-click on the variable “Path”

   

4. Then, simply add ;c:\cygwin\bin to the end of the variable section of the pop-up.
5. You can then safely “Ok” out of all the open windows.
6. Restart your computer. A reboot is required for the path variable changes to take effect.

Once rebooted, you can then issue your chosen linux commands in the Windows Command Prompt:

C:\Documents and Settings\Administrator>ls -la

Download Firefox 1.5

• Drag-and-Drop tabs – We all love the tabs in Firefox. As such, the Mozilla foundation has taken it a step further by allowing you to drag your tabs around to modify their horizontal position.
• Download Manager – You now have more controls in regard to the download manager. You can have the list cleared each time Firefox exits, upon successful download, or the traditional manual method.
• Image blocking – If you are paranoid about stumbling across an offensive image on the Internet, this feature is for you. You can either whitelist or blacklist sites by domain name. You can even blacklist all domains and only specify domains on your whitelist. Using this method Firefox won’t load any images from any website unless you specifically allow it.

For a more thorough preview of new features and changes, I recommend the following podcast:

• forward and backward movement within a file
• searching (including regular expressions) and highlighting
• watches on the end of the file (similar to tail)
• line numbers
• toggle line wrapping (useful for large log files)
• open simultaneous file
• many more (see )

To run less, simply type the following command (prompt$ = your shell prompt):

prompt$ less helloWorld.txt

Below you will find some tips on how to use less once it is up and running.

Navigation:
You can then navigate up and down through the file with the arrows, or the page-up and page-down keys.

Searching:
To initiate a search, simply press the “/� to bring up search prompt. Then either enter a string or regular expression and hit enter. Less will then highlight all matches. To keep searching through the file, simply press “/� and hit enter once more to look further for the previous phrase. HINT: Use the search feature in conjunction with the file watch command to highlight your search phrase in incoming data.

Watches:
To initiate a watch, you can issue the command “F� while running less. This will tell less to start examining the end of the file for incoming data. This can be very useful to keep an eye on raw web access or error logs, as well as system and mail logs.

Wrapping:
To toggle line wrapping, issue the command “-S� while running less. Note that once line wrapping is disabled, you can scroll left and right with the arrow keys to see the extended data.

For more information on using less, please refer to their website at: http://www.greenwoodsoftware.com/less/)

NOTE: If you don’t have less installed, see your specific distribution docs or download it from here.

Take my word for it and add the program “less� to your bag of tricks, right away.
