RE: Uses in h.s.APcalculus
To: People interested in Mathematica labs for Project CALC From: William H. Barker Department of Mathematics Bowdoin College Brunswick, Maine 04011 wbarker at bowdoin.edu (207) 725-3571 Date: August 27, 1992 Subj: Instructions for ftp receipt of Project CALC Mathematica labs. It is now possible to obtain the Mathematica labs produced at Bowdoin for Duke University's Project CALC program via anonymous ftp. This document tells you how this is done. If you are unable to use this method and would prefer to receive the labs on disks via the ordinary mail, send such a request to me. Currently Releases 4 and 5 of the labs has been placed in the ftp files. Detailed descriptions of the contents of each release will be found in the files README-Rel-4-ftp and README-Rel-5-ftp. Release 5 contains the newest versions of the laboratory notebooks (as of mid-June), all fully compatible with Mathematica v2.0---in particular, most of these notebooks will not run under v1.2. For this reason, Release 4 has been retained as a convenience for those who are still using Mathematica v1.2. By the end of the summer we intend to post Release 6, which will contain revised versions of the laboratories. The revisions to the first and second semester labs will be relatively modest; the bulk of revision work will be with the third semester labs. We also intend to post important revisions as they are completed (i.e., prior to Release 6) in the area pub/calculus/revisions. Those of you interested in having the most current versions of our labs should check this area regularly. In particular, we have just added the file SpecialItems.sit to the revisions area. This was accidentally left out of our original configuration of Release 5. A short description of the file will be found in the text document rel5correction.txt. If you wish to receive information from us on a regular basis, please send a request asking to be placed in our "Dissemination Network." What follows is a sample ftp session along with some explanatory comments; this should enable you to obtain any file currently in our ftp directory. (I wish to thank my colleague Steve Fisk for designing and setting up this ftp directory.) NOTE: The workstation 'POLAR' on which the ftp files are found has been experiencing a lot of problems this summer. If you have difficulties connecting to POLAR, or if the ftp commands do not seem to be yielding the desired results, disconnect and try again later. Hopefully these problems will be solved shortly. ------------------------------------------ Logon to a computer with Internet access and enter ftp polar.bowdoin.edu You will be answered by the following statements: Connected to polar.bowdoin.edu. 220 polar.bowdoin.edu FTP server: ready. Now login with the username 'anonymous' and your e-mail address as the password. Name (polar.bowdoin.edu:): anonymous 331 Guest login ok, send ident as password. Password:your-e-mail-address 230 Guest login ok, access restrictions apply. You now can connect to the appropriate directory. Depending on what you wish to receive, the last phrase in the directory name will be either release-4, release-5, or revisions. ftp> cd pub/calculus/release-4 200 PORT command successful. You now can ask for a list of what is in the directory ftp> dir 200 PORT command successful. 150 Opening data connection for /bin/ls (18.104.22.168,1649) (0 bytes). total 3984 -r--r--r-- 1 801 502 872 Jun 11 09:00 README-Rel-4-ftp -r--r--r-- 1 801 502 1391872 Jun 10 15:43 rel4-1.sit -r--r--r-- 1 801 502 1276672 Jun 10 15:43 rel4-2.sit -r--r--r-- 1 801 502 1384192 Jun 10 15:43 rel4-3.sit 226 Transfer complete. 210 bytes received in 0.17 seconds (1.2 Kbytes/s) To transfer an individual file use the following command: ftp> get README-Rel-4-ftp To transfer all the contents of the current directory use the commands ftp> mget * mget README-Rel-4-ftp? yes (you will be asked about each file) To change to one of the other directories use the command ftp> cd ../release-5 To quit: ftp> quit -------------------------------------------- Once the desired files have transferred to your Internet-connected computer, the README files can be opened immediately. The remaining files must be transferred to a Macintosh and decompressed: they are in the form of Self-UnStuffing StuffIt Archives. You do not need to have special software to perform the decompression. At Bowdoin we transfer files of this nature from POLAR (a UNIX workstation) to a Macintosh via TCP/Connect. The settings needed for this transfer are 'Image' and 'MacBinary'. Other users have indicated that "Fetch" also works nicely. We have, however, heard of problems when using "MacIP"---for that reason we suggest not using this program when working with our files.
