Remove saved credentials or password stored in Windows 7

If you are facing problems regarding connecting to a network drive and the system did not prompt you for a username and password. Most likely, you had already a password being saved in the system already. You could type this command to check the credentials that had been stored previously.

rundll32.exe keymgr.dll, KRShowKeyMgr

From here you can remove authenticated network shares so that the next time you will have to type in the credentials again.

Merging multiple mp3 files into a single mp3 file for Mac OS X

Trying to create rip an audio book into mp3 while I faced this problem.

Basically, the audio book CD came in various tracks in it.
After ripping it from iTunes to mp3, multiple mp3 files had been created which is not very convenient to manage or listen.

Here is a command from the Terminal which I used to merge the multiples mp3 files together >>

for i in *; do echo $i; cat $i >> bigfile.mp3; done;

This command will actually join the mp3 files together and show the sequence it was being joined. Please rename your file in sequence and make sure there isn't any spaces in the filename.
