Must I do the assignments in a Mac Lab?

Even though it is possible to do most of the assignments at home, the assignment instructions are written with the idea that you will be doing them in a lab (PC or Mac, depending on the assignment) on campus. Turning in the assignment from home requires some mastery of FTP or using a floppy to copy to a lab machine.

I have a PC at home.

Due to the large number of you with your own computers, we will try to provide some details how to use your PC or Mac from home as we get further into the course. The guidelines are:

• You must turn your assignment in where we will be looking for it; e.g., in your Appleshare disk space, or your Win95/PC file server space, depending on the assignment. And in the correct sub folder!
  • This means using FTP to copy your work over the network, or
  • Bringing a floppy with your work on it, and copying it over in one of the Mac or PC labs.
• You must turn your assignment in such a way that we can grade it. For example, if you use Microsoft Office 97 for the PC at home, and the class is using Microsoft Word version 5 on the Macintosh, then you have to save your work in a format that can be read in Microsoft Word version 5! If we can't open your work to grade it, you'll get a 0 (zero) .
• It's best (but not necessarily required) that you use the same applications that we use in class; e.g., Microsoft Word and Excel, and Netscape.
• If you elect to use a computer at home, it would behoove you to try opening your saved work in a lab here at UCSD to verify that we will be able to open it to grade it.
• If you do you work using a different application than we use in class, we may not be able to help you if you get stuck!

First, make sure that you select the correct Zone in the Chooser window (lower left pane). The correct zone is: ACS-iCogSci1, and it is likely that you will have scroll the list of zones in the Chooser window in order to select it. Then select the class server: iCogSci1-netatalk. Now you should be able to log in with your cg3xzz account.

And also make sure that the "caps lock" key is not on, as both the account name and password are case sensitive.

Can't Log off Appleshare

There are applications open/active that are using something on your file server disk, even though they may have no windows open!

1. Open the Application Men (icon on the far right of the menu bar).
2. Locate the offending application, Eudora, Excel, and MS Word are the most common culprits.
3. Select the application
4. Select Quit in the File menu, or CMD+Q.
5. Now you should be able to drag your Appleshare disk icon into the trash to log out.

6. Or, just select Restart in the Special menu of the Finder.

• The error should not keep you from doing the assignment. That is, if you ignore it, things work right anyway.
• I believe that if you Quit from Eudora (CMD+Q), and then restart by double clicking the Eudora Settings document in your Eudora folder on your Appleshare disk, you won't get the error any more.

  Note the difference between Quitting and having all windows closed.

• If you have sent email to cg3zyy and received 2 acknowledgments, you are done with the assignment. Make sure you have sent the message to cg3zyy, and have 2 separate acknowledgments!

There are several ways you can go. If you want to copy the files to your home computer, there are 2 basic methods.

Assuming you are using Windows, and you have network connectivity with UCSD, you can copy/FTP your web files to your own home computer.
1. Establish a network connection using your ISP. (This varies a lot from ISP to ISP, so we can't really describe it here.)
2. Start->Programs->MSDOS_Prompt. Newer versions of windows have moved it to Start->Programs->Accessories->CMD_Prompt.
3. In the DOS Window, type: mkdir c:\cogsci3
   This will create a new folder called cogsci3 on your main (C:) hard drive.
4. Type: cd c:\cogsci3
   Just like UNIX, huh?
5. Type: ftp icogsci1.ucsd.edu
6. You will be prompted for your icogsci1 (cogsci3) login and password
7. After you log in, you will get an "ftp>" prompt, type: cd public_html
8. Type: binary
   to make sure the images copy okay
9. Type: mget *
   Remember wildcards? The "*" means every file in the current folder. This will also match folder names like topic which you don't want to copy!
10. You will be prompted for each file to copy; type "y" followed by the enter key for each file you want. But type 'n' or just the Enter key for folders that you don't want to copy.
11. When they are all copied, type: quit
Or you can go to a PC lab on campus with a floppy.
1. Log into your Windows File Server. (The procedure varies depending on what windows version is running).
2. Insert your floppy.
3. Open the "My Computer" desktop icon and then open the floppy (A:) in "My Computer"
4. Open your H: file server icon (on NT machines), or log into your "Class Resources" (Windows XP).
5. Open your public_html folder
6. Select all the files (Ctrl+A), and drag them to the window corresponding to your open A: (floppy) drive.

To display your index.html or topic.html, use "Open Page" or "Open Document" or "Open File" in your browser instead of "Open Location", and, of course, specify c:\cogsci3\index.htm or c:\cogsci3\topic.htm for the file name.

Here's a brief summary; it assumes your personal account is jdoe on sdcc17, and your icogsci1 account is cg3xzz. If you already have a personal webpage, read through the instructions before you start so that you don't accidentally clobber your existing files.

1. The easiest way to copy the files is to use Windows file sharing in a campus PC lab
2. Log into Windows XP
3. Then open your "Class Resources" folder and log into both your class home directory (cg3xzz) and your sdcc17 personal account.
4. Open your cg3xzz home directory folder, select public_html (and perhaps your hw4, hw5, and hw7 folders too, though all that material should have been copied to public_html), and copy it.
5. Open your sdcc17 home folder, and then paste. All of your public_html folder and contents should be copied over to your personal account now.
6. To maker your files appear on the web, you'll have to chmod your public_html folder and your home folder (and perhaps all the files in your public_html folder too). See below

1. SSH to your personal account machine (say, it's sdcc17), and log in and jdoe (of course).
2. Now you need to create a web directory. Of course, if you already have a web page (and, therefore, public_html directory), you can skip these steps.
   1. Type: mkdir public_html
   2. Type: chmod o+x ~ public_html
3. Type: cd public_html
   1. If there are sub folders in your public_html folder (like the topic folder in Spring 2003), then also mkdir each of those.
4. Type: ftp icogsci1, log in with your cg3xzz account and password.
5. At the ftp> prompt, type: cd public_html
6. At the ftp> prompt, type: binary
7. Now copy over your .HTML document(s) and images. If you are creating a personal website for the first time, you can copy everything at once, if you wish. If you already have a personal website, you probably will want to copy only selected files, like in the next section. (In particular, you probably don't want to copy the course index.html file, since it will clobber the index.html you already have!) To copy all the files at once, using a wildcard:
   1. At the ftp> prompt, type: prompt
   2. At the ftp> prompt, type: mget * Remember wildcards? The "*" means every file in the current folder.
   3. You should now see messages about your web files being copied.
   Or you can selectively copy files, one at a time.
   1. At the ftp> prompt, type: ls
      This will give you a list of the names of your images and documents. Suppose one of the images is called eagle.gif:
   2. At the ftp> prompt, type: get eagle.gif
      to copy that one image. Repeat for each file you want. But don't try to copy the sub folders (like topic) if you have them. Again, don't get files with names you already have in your personal website, because the course files will clobber/replace those. In particular, be careful about the index.html file.
      1. If you have sub folders, type: lcd SUBFOLDER at the ftp> prompt to change into the sub folder called SUBFOLDER on your local machine (which you should have made previously).
      2. Then cd SUBFOLDER to get into the similar folder on the class machine.
      3. Then do a mget * to copy all those files
      4. When done copying all files, do a cd .. to get back to your public_html folder on the class server, and lcd .. to get back to it on your personal server.
      5. Repeat for as many sub folders as you have on the class server.
8. At the ftp> prompt, type: quit
9. Type: chmod o+r *
   which will make all your files "Readable" to the web software.
10. Type: chmod o+x ~ ~/public_html
    which makes your home directory and web directory "aXessable".
11. Try to access your files as: http://sdcc17/~jdoe or http://sdcc17/~jdoe/topic.html
