The other day we were toying around with filtering out the horn noises from the World Cup matches streaming from ESPN. We found some instructions dealing with Fedora but many of the packages that were recommended were not available for CentOS. One of those packages was jack-rack which can be downloaded and installed using the information below.
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.
Booting Mac OSX into single user mode is fairly easy though I did run into an issue when using a Windows USB keyboard. Single user mode will allow you to modify the system without logging in for items such as changing the Mac OSX administrator password. Follow the directions below to boot into single user mode on Max OSX.
Recently I was doing some testing with various audio settings on a CentOS Linux desktop and found out fairly quick that many of the packages I needed were not available. After some research I located a repository from Stanford’s Center for Computer Research in Music and Acoustics called Planet CCRMA which is pronounced karma. Below I describe how to install the CCRMA repo on CentOS Linux so you can use yum to install various audio RPM’s.
