Microsoft Flight (Free Flight Simulator)

Microsoft has a long history of creating flight simulators.  I remember playing the first version of Microsoft Flight Simulator on an Apple II+.  It was crude by today's standards, but it was state of the art back in the 80's.  Flight simulators now seem second only to the real thing.

If you love flight simulators, check out Microsoft Flight.  I need to note that there are two versions.  The  free version includes basic content you need to get started.  There's also a premium version that has expanded content.

All Hail IPv6 as King, IPv4 is dead...

For decades IPv4 was king because it was the dominate networking protocol for Internet and corporate Intranet communications.  Although its rein has come to an end as the pool of publicly available IPv4 addresses (the numeric addresses assigned to every device on the Internet) was officially depleted as of February, 2011.

Its been known for a long time that the publicly available IPv4 address space would be completely depleted so in 1998 they started drafting a next-generation networking technology known as IPv6 to replace it.

For years several ISPs and Internet companies have been testing and deploying their networks to be able to carry both IPv6 and IPv4 traffic. They have also offer "tunneling services" that allow IPv6 customers to access IPv4 sites. 

June 6, 2012 was designated as "World Launch Day" for IPv6.  Several major ISPs and Internet companies permanently enabled IPv6 on their public Internet sites.

The IPv4 and IPv6 are majorly different network protocol, but have been designed to interoperate with each other so that they can co-exist on the same network.  


One of the first fundamental differences between the two protocols is the size of the address space (e.g. the amount of device that are supported).  The IPv4 protocol supports a maximum number of over 4 billion (4,294,967,296) public IP addresses.   The  IPv6 protocol supports a maximum number of over 340 undecillion (340,282,366,920,938,463,463,374,607,431,768,211,456) unique addresses. 

The following Microsoft operating systems include full support for IPv6: Windows Vista, 7, 8 and Windows Server 2008 and above.

Note: Windows XP does have support for IPv6 but its not native to the OS.

Brief Note: IPv6 to IPv4 Tunneling
For older IPv4 networks that don't currently support IPv6, there are a few different protocol transition technologies.  For example, there is "6to4 Tunneling" which is able to encapsulate IPv6 packets within IPv4.  Basically what this technology does is take one type of network data (e.g. IPv6) and translates it into another type (e.g. IPv4) then broadcasts it over the network.


IPv6 Checklist
Below is a checklist of items that you have to have in order to use IPv6 on your computer and network.

• An operating system and applications can that supports IPv6 (Note: applications have to be specifically updated to support the IPv6 protocol)
• The most current versions of Windows (Vista and above), Linux or Mac OS X.
• A router appliance (commercial or consumer) that supports IPv6.
• Most modern routers  support IPv6, older models may require firmware update if available (check hardware manufacture's web site for more information).
• An ISP with IPv6 protocol and DNS support.
• IPv6 readiness will vary between companies.  Contact your ISP to find out the type of IPv6 support they offer.
• If you're ISP doesn't support IPv6 you can use an IPv6 Tunnel Broker like Hurricane Electric to allow your computer to access the IPv6 Internet.

Testing Your IPv6 Readiness
Want to check out your networks IPv6 readiness?  Run the following test (http://test-ipv6.com/) from your browser and it will tell you whether its IPv6 network is ready or not. If you  already have an IPv6 network running, this site offers a good way to test if you have any problems or other issues.

Other was to test if IPv6 is working properly on your network, run the following two search queries on Google and they will show you your publicly available IPv4 and IPv6 address.

• IPv6 Test (requires an IPv6 network)
• IPv4 Test (requires an IPv4 network)

Learning More
Want to learn more about IPv6, read the following article, "Introduction to IPv6".  Also check out a site called Hurricane Electric (H.E.).  H.E. also offers an unofficial IPv6 certification.

Windows Defender Offline (Offline Virus Scanner)

Everyone should have an up-to-date real-time anti-malware application running on their system at all times.  These programs won't guarantee that you will never get infected by a rouge application (e.g. virus, Trojan-horse, worm, root-kit, etc.), but it provides better protection then not having this software running at all.

If your computer starts acting strangely, you might want a second opinion to see if your system is actually infected.  This is why there are offline virus scanners for checking your system for malicious software.

There are several vendors that offer this type of software, but one of the newest is from Microsoft and called the Windows Defender Offline.  Below is excerpt from the site: "Sometimes, malicious and other potentially unwanted software, including rootkits, try to install themselves on your PC. This can happen when you connect to the Internet or install some programs from a CD, DVD, or other media. Once on your PC, this software might run immediately, or it might run at unexpected times. Windows Defender Offline can help remove such hard to find malicious and potentially unwanted programs using definitions that recognize threats. Definitions are files that provide an encyclopedia of potential software threats. Because new threats appear daily, it's important to always have the most up-to-date definitions installed in Windows Defender Offline. Armed with definition files, Windows Defender Offline can detect malicious and potentially unwanted software, and then notify you of the risks."

Article: Internet Backup Solutions (An Introduction to Cloud Backup Services)

Here is an excerpt from an article that provides a brief introduction cloud backup services: "Backing up data on your computer has always been critical. A long time ago floppies were used to backup your data, later it was CDs and then DVDs. Today there is no affordable external removable media capable of keeping up with modern multi-terabyte drives.

Even if you have an external drive or NAS (network attached storage), it can be damaged, lost, stolen or suffer data corruption. If you don't have an off-site backup, and your local backups are in-tact they can be damaged by fire, earthquake, or other natural disasters." (read the rest of the article)

Leap - Motion Control Gestures

Leap appears to be a very cool technology that supports accurate motion control that allows you to interact with your computer in three dimensions with natural hand and finger movements.  Its currently only in pre-order availability (US$69), but its supposed to be available in a few month for the Window 7/8, and Mac OS/X.

Setup is supposed to be easy. Just plugin the device to a USB port, load the Leap Motion software, and do a quick wave to calibrate it.

Personally I want to try it with Windows 8, it might be a great alternative to having touchscreens for a mouse for the new OS, for me the technology seems worth trying out.  I will post an update if I like it.

Microsoft SkyDrive (Free Cloud Storage, with Local File Access/Syncing)

Microsoft offers a cloud storage service called SkyDrive.  If you already have a SkyDrive account you had 25GB of free storage space, but you better "opt-in" to keep it, otherwise you will lose it.  For new users who didn't already have an account will get 7GB free storage, and can opt to buy more space if needed.

Microsoft recently added a new feature to this service allows you to use Windows Explorer to access the file in your SkyDrive account on your local computer. You need to install the SkyDrive client on your machine and it will create a folder (located in the Users\<your user name>\SkyDrive path) on your PC that is automatically synced with the SkyDrive service in the cloud.

Free Photo Morphing Tool

Looking for a tool that transforms your photos into another one? Check out a tool called Fotomorph.  Make sure view the sample projects to see how it works, just use the play button at the bottom to see the morph in action.  

Here is an except from a CNet review: Digital imaging and graphic design software is often the victim of one of two problems: either it's too advanced for everyone but expert users, or it's too basic to do anything very useful. FotoMorph is one of the rare programs that manage to deliver impressive results with very little know-how. This fun application lets users create animations that morph one photo into another, no experience required."

Software: Skype Auto Recorder

Skype is a great tool for making calls over the Internet, using either computer-to-computer or from PC to mobile phones and landlines.

Skype Auto Recorder is a free open-source application that allows you to automatic record Skype conversations into MP3 files. It also provides the ability to filter who is recorded and the destination file location based on the contact name, and improve the output sound quality.

NOTE: Make sure to check the laws in your jurisdiction regarding the recording of telephone calls and electronic communications.

Optting Out of Behavioral Advertising

Are you concerned about your privacy in relationship to Internet advertising? The Network Advertising Initiative (NAI) offers a tool that allows you "opt out of behavioral advertising" that is utilized by its members.

This is not all an encompassing tool, there are a lot of caveats, but it does offer some control over your online privacy. It doesn't allow you to opt out of web advertising, it only allows you to "opt out" of the behavioral advertising delivered by its member companies.

Behavioral advertising is used to precisely target Internet advertising at you based on your surfing habits. These companies track you by placing their ads on web sites and using their cookies to track where you're surfing.

To opt out of an NAI member's behavioral advertising program, go to the tool,  check the box that corresponds to the company (or press the button labeled "Select All"), then press the the "Submit" button. The Tool will replace the specified advertising cookie(s) and show your opt-out status.

Windows 7: Backing up EFS certificates

Do you use the Encrypted File System (EFS) that's built into Windows 7 (which is included in Pro, Enterprise and Ultimate versions of the OS) to protect your data on your local hard drive?  If so you should make sure that you back up the EFS certificate so you can recover your encrypted data if the stored keys on your hard drive get accidentally corrupted or deleted.


To backup the EFS key, use the following procedure:

• From the Start menu in the Search field, type CERTMGR.MSC, then press the ENTER key to open the Certificate Manager.
• Expand the Personal node, and click Certificates.
• Scroll down to find the certificate that shows "Encrypting File System" in the Intended Purposes column, and click it.
• Click Actions > All Tasks > Export...
• On the first page of the Export Wizard, press the Next button.
• Click Yes, export the private key and press the Next button.
• Click Personal Information Exchange and press the Next button.
• Create a password to encrypt the private key file, then press the Next button.
• Enter a file name and location (or press the Browse button to navigate the local drives) to store the certificate.
• Press the Finish button.

Notes: In the Certificate Manager if there is more than one EFS certificate make sure to back them all up on some type of removable media (such as a USB key or external hard drive). Then store that device in a safe physical location.
