isohome Isohome is a simple script that tries to make an image of your CS home directory that is suitable for burning onto a CD or DVD. It will confirm that you are running it from the machine where your home directory is actually a local disk. If not it will tell you which machine you need to run the script from.

Programs using acm.jar may be compiled and executed from the command line, or within your favorite Java IDE (e.g., Netbeans, DrJava).

SSH Keys on Microsoft Windows using the PuTTY Utility SSH keys are what you will use to establish an encrypted connection over the network, e.g. the internet, between your system and a remote machine. The default type of key to generate is RSA which is good for most purposes. RSA is universally supported among SSH clients. Note that EdDSA performs much faster and provides the same level of security with significantly smaller keys. In general, though, for what you need to do, RSA encryption is …

System Priorities Priorities of programs are something to be aware of. PS The first thing to do is to get to know your processes. The ps command lists out the processes you have running on the system. By using ps -l, an extended listing of your processes is provided. The fields of the most interest to this topic are the PID, NI, and COMMAND fields. The COMMAND field lists the name of the command that started your process. So, if you're looking for your runaway c++ program, a.out is the one yo…

Pickup allows you to place files for pickup in your course directories such that those files cannot be read by your students until they run this script. At that time an entry is logged showing the date, time, user and directory that was picked up. If your students attempt to kill the script (say, after it copies the files and before it logs that it has) that attempt will also be logged…
