This sheet is a model only. You should copy it and customize it for your own home web site. Delete items that you already know. Add quickie references that you frequently forget or have to ask someone about. BY THE WAY, if you know of a better solution to any of the issues below, tell me right away, or share them directly with the class. I always have more to learn, and I depend on my students to teach me.

MacLab Tips and Tricks

Using the MacLab
Checking Email
Using Fetch
Printing in the MacLab
Some Simple UNIX Commands

Using the MacLab

First thing when you come in, check to see what applications have been left open on your machine and close them to save memory.

When using your own software or the shareware that I give you, drag the application onto the machine's hard drive when you start your session. You will get better performance than if you try to use it from the floppies or M.O.

When using a memory intensive program you might want to drag it from Lab Applications to the machine's hard drive, and then increase its memory alotment.

Backup all your work to floppies. Write your name on all your floppies and remember not to go off and forget your disk in the machine.

At least once a week, dump all your floppy files into one big folder on Lab Scratch with your name on it. Then go over to a machine that has a M.O. drive on it, insert your M.O. Archive Disk, and copy the folder from Lab Scratch onto your M.O. Remember to put your NAME and EMAIL ADDRESS and PHONE NUMBER on your M.O. Archive Disk in case you should forget or lose it.

If you have an IBM/Win machine at home, you can use IBM disks in the MacLab. But there is a trick. Don't get them mixed up with your Mac disks. Create text files at home in your word processor. Computers in the MacLab can read text files on IBM formatted disks. I believe the versions of Word and Pagemaker in the lab both have filters that will read files of most IBM major word processors like Word and WordPerfect.

If you want to open Mac files on your home machine, you will need to do one of two things: In Word, save it as IBM format or text only file. Be sure to follow the filename conventions for IBM. OR, use Fetch, transfer the text file to your UNIX account, and then use your home modem and Kermit to ftp the files to your home machine.

Checking Email

Email in the MacLab can be a tricky thing. I tend to use the MacLab to check and answer email, and then I go over to a UNIX workstation and use Zmail to handle archiving files and housekeeping chores. Obviously, Zmail is easier to use on a workstation. As part of our class collaboration, we will be archiving many of our email threads, so you may want to learn to use folders on Zmail on UNIX workstations. It is not hard.

To check email in the MacLab, go to the Apple menu and slide down to Telnet Sets. Open an NCSA Telnet window and login as you would usually. This is also how we will enter UNIX commands from the MacLab. You can MOO from this window as well, but I prefer MOO client shareware for reasons we will get to later.

After you have logged in, type zmail at the prompt. If you know how to use UCB mail you can use it. I have never bothered with UCB mail.

Command line email is often counterintuitive. I will help you figure it out. Here a a couple of key commands to remember:

Using Fetch

Fetch will probably be one of our most used programs. It is a file tranfer utility that is invaluable for Web Work. Use Fetch and the Telnet Window to manage the files in your UNIX account from the MacLab.

Open Fetch and open a connection to rcs.rpi.edu. Configure the program to your home directory (~userid) or our class web (/dept/llc/media/web). Enter your password.

Get or Put files according to your needs.

Remember! Send text files as text only, not bin/hex.

Remember! Send pictures as .GIF files as RAW DATA, not bin/hex.

If you want to use Fetch to get files from around the world, use a protocol called "anonymous ftp." When you go to faraway places with Fetch, enter "anonymous" as your name, and put your email address as your password, userid@rpi.edu. Roaming the world and getting files is a lot of fun. Stay away from those nasty kiddie porn and bomb building sites tho. Boooo.

Printing in the MacLab

Printing in the MacLab is easy once you know how.

Go to the Apple menu and select Chooser.

In Chooser, select AppleShare.

Then select rcs spooler server. Double click.

Enter your name and password at the prompts. Hit OK.

Still in Chooser, select Laserwriter. A list of campus printers will come up. The laserwriter in our lab is called 4711. The color printer in our lab is also 4711 PHASER. That is how you tell the difference.

If it turns out that our laserwriter is down, you can easily send your print job down the hall to Sage 4510. Just remember to run down there and pick it up. If that printer is down, send it to Sage 3101, downstairs.

You can also send print jobs to the VCC. In case you didn't know, the VCC has a really neat color overhead service that you can access through the MacLab. It costs a bit more tho.

A little cartoon figure will appear on your desktop when you are set up to print. WHEN YOU ARE DONE WITH THAT MACHINE, REMEMBER TO THROW THE LITTLE CARTOON IN THE TRASH. If you don't, someone else could come along and print all kinds of stuff and your account would be charged.

Some Simple UNIX Commands

UNIX is a pussycat. I use it on a need-to-know basis. I refuse to learn any commands I don't use regularly. Here are some commands I do use regularly.

ls to list the contents in any given directory.
cd to go to your home directory, or to change directories if you specify where you want to go.
cd .. to go up one directory level.
fs la to look at the permissions you have set for your home directory, or to make sure you have permission in the class directory.
fs lq to see how much memory you have left.
mkdir blahblah to create a directory.
rmdir blahblah to remove a directory. Make sure it is empty first.
cp to copy files from one directory to another. Must be coupled with filename and path.
rm to remove a file. Make sure you don't delete something you will need later.
