How to Capture a 4 way WPA handshake

Trying to capture a 4-way TKIP handshake without help can involve sitting and watching traffic for hours and hours, waiting for a client to connect to a network. By using a tool called aircrack-ng we can forcefully deauthenticate a client who is connected to the network and force them to reconnect back up. During the process of re-exchanging the encrypted WPA key, you will capture a handshake. In order to forcefully capture a 4-way handshake, you will need to deauthenticate a client computer that is actively using services, forcing it to exchange the WPA key and in turn capturing the handshake that can be decrypted.

WordPress Syntaxhighlighter Evolved: No Wrap Alternating Background Colors Cut Off

I have been using the WordPress Syntaxhighlighter Plus plugin to display code for quite awhile now. Today I wanted to check on recent updates and through reading on the developers site found out that the code is no longer maintained and he recommends people use the WordPress Syntaxhighlighter Evolved plugin instead. I decided to go ahead and download the Syntaxhighlighter Evolved plugin and test it on my development site. I was pleased immediately with the choice and knew that I would be moving it live as soon as I had any kinks worked out. There was only one thing holding me bac which was the fact that with the code wrap turned off the CSS for alternating colors and for the highlighting was cut off when you started to scroll to any code that spilled out past the default size. The plugin also blew out the right side of my site a bit so I needed to modify a couple CSS width parameters. I describe a workaround for the alternating colors being cut off below as well as how to set the width so it doesn’t blow out your layout.

Technology Errors

Windows Defender: This operation returned because the timeout period expired. (Error Code: 0x800705b4)

I recently received a new Dell laptop that has Windows 7 Ultimate 64-Bit as the operating system. A friend and I were discussing virus protection software as well as spyware protection software and how Windows 7 handles each. I am a big fan of Windows Defender so I was looking at the configuration on my Windows 7 computer and realized that the Windows Defender service was not starting. I hadn’t even realized this because I typically turn off the Virus, Spyware, and Firewall messaging that Windows complains about if you don’t have each installed the way the OS wants. So needless to say I was surprised that Windows Defender was stopped. It took me awhile to finally figure out how to resolve and I came across a bunch of issues that others may have so below I describe the error, steps I took to resolve, and final resolution.

Windows 7 Keyboard Sortcuts

One thing I love is key board short cuts. I have been scouring the net and making a list of all the keyboard shortcuts which are new in windows 7.  I will continue to add them to this post as I find them. Not all of these are new but I am adding them all in order to have one complete list. This will also be a reference point for me as well.
