Thoughts about electronic mail
I end up talking to students about email more than they or I would like. Here are a few quick notes about ways in which I use (and do not use) email.
Choosing subject lines
I get way too much email, hundreds of messages each day. I rely on programs to automatically file my email and to search my email. Hence, I’d appreciate it if you’d help me process email from you more carefully. Here are a few short guidelines.
- Please take the time to choose an appropriate subject line for your email message.
- If I tell you to use a particular subject line for an email message, particularly for an assignment, please use that subject line. The correct subject makes it easier for me to file your email and, more importantly, for me to find your email. The typical subject line is “CSC 322.01 Assignment: Title (Your Names)”. For example, in submitting the typical introductory survey, I might use the subject line “&courseid; Assignment 1: Introductory Survey (Samuel A. Rebelsky)” or the subject line “CSC 322.01 Assignment 1: Introductory Survey (Rebelsky)”.
- If you are asking for help on an assignment, please do not use a title like “Homework assignment”. I generally assume that titles like that represent submissions of homework assignments, and may file them without looking at them until it comes time to grade the assignment. If you’re asking a question, please put a term like “Question” or “Help” or even “HELP!” in the subject line. (Yes, I know that the use of all capital letters is a form of shouting. It’s okay if you virtually shout when asking for help.)
- If you are replying to a message and are changing the topic of the message, please also change the subject line. If you want to be precise, you can include the old subject line in parentheses, prefixed by the word “Was”, as in “Question on the assignment (was re: This week’s convocation)”.
I do my best to respond to email within twenty-four hours. If I do not do so, you should feel free to email me a reminder. If you have an urgent question, please send it via email with “Urgent” in the title. If I do not respond quickly enough, you can feel free to text me. If you do text me, please include your name. And don’t text without sending email first.
Authentication and encryption
Most of us, myself included, don’t think much about email, other
than that it’s a convenient way to communicate. But a few recent
events suggest that we should be a bit more thoughtful. Hence,
I encourage you to consider using mail encryption software,
Since I use GPG, I’ve written
GPG is available for all three major operating systems (and probably for others, too).
- On the Mac, I use GPGMail 2. I find it simple and straightforward.
- I don’t use Microsoft Windows, but I hear that gpg4win works pretty well.
- On the Linux workstations in the MathLAN, GPG is installed as a command line tool.
If you send me your public key (or a link to your public key) and
ask me to encrypt email to you, I will do my best to remember
(although I may not always succeed). You can find my public key
