Yesterday afternoon a friend dropped his computer by so I could make it go a bit faster which I initially thought must just be some application using up a ton of resources or something. The issue ended up being that the computer was an older PowerPC G4 running Mac OSX 10.3 that didn’t have a lot of RAM and hadn’t been updated in a long time. I happened to have PC133 RAM to stick in it so I added 512MB of RAM and then attempted to begin the software updates which requested his administrator password which I did not have. Turns out that he didn’t have the password either so below are directions on reseting the administrator password on a Mac running OSX. The process take a little while as you are required to boot into single user mode, go back through setup, modify the admin, and then delete the temporary admin account.
I use Cygwin on Windows to make my Windows only computers as comfortable as possible to me. This comfort is provided by the Linux command line utilities that allow me to work. Cygwin provides a way for me to run these utilities from a Windows 7 command prompt. Two utilities that are really useful that are not installed with Cygwin by default are SCP (Secure Copy) and SSH (Secure Shell). Both of these utilities allow secure communication with remote computers. Below I describe adding them to an existing Cygwin Windows 7 installation.
