IBM Java SDK Install Error: Failed dependencies: /usr/lib64/ is needed by ibm-java-x86_64-sdk-6.0-9.1.x86_64

While setting up a websphere test server I ran into a minor dependency error during the beginning of installing the necessary packages for websphere. The IBM Java SDK RPM on CentOS 6 was complaining about a failed dependency of a libstdc++ library. The RPM I was attempting to install required and CentOS 6 has installed by default. All that is required is to install the libstdc++ compat RPM. The information below describes the error in more detail, how I located the package that installed the necessary file(s), and an example of installing the needed package.

Photoshop ICO Plugin, How To Open Windows Icon Files In Photoshop

Earlier this afternoon I needed to modify a .ICO, also known as Windows Icon, for some testing I was doing with X-Chat which is a GUI based IRC (Internet Relay Chat) client. Anyhow it slipped my mind that Photoshop does not even recognize ICO files by default. Adding Windows Icon (ICO) support to Photoshop is really easy though and I remembered from a previous experience the process to add a ICO plugin to Photoshop. Follow the directions below to open, edit, and save ICO files on Windows.

Nmap 5.51: Zenmap: Error Saving Snapshot: Surface.write_to_png takes one argument which must be a filename (str)

I upgraded to Nmap 5.51 early this afternoon because a friend asked me to take a look at creating a topology image of a network scan of around 3,000 hosts. After upgrading I opened his scan in Zenmap and attempted to export the topology of the scan as a PNG but I received an error which I at first assumed was an issue on my computer or an issue with the fact that the export to PNG image was taking place on a 64-bit Windows 7 computer however both of those turned out to be incorrect. Below I describe the error in more detail as well as the current newest Nmap version that will allow PNG export, a workaround for the issue, and notes about the response from the Nmap development team that already pushed a fix to SVN only a couple hours after the issue was reported (+1 Nmap devs!).

Create Symbolic Links Windows 7

While testing something earlier I needed to create a symbolic link on my laptop which is running Windows 7 Ultimate 64-bit. I first was going to use cygwin to create the symbolic link with ln however cygwin complained about it which is noted below in more detail. After receiving the error from cygwin I decided to look at the possible Windows commands and located mklink which is described in more detail below and will easily allow you to create symbolic links on a Windows 7 computer.
