Do and do not in laserprinter d) When the printer is stalled e) biomed/UNIX users may delay long prints, using the command: at f) MAXC/VMS users may hold/release/delete prints in queue of pc computers: g) Laserprinter h) WordPerfect i) Epson 10. Friendly pico editor in biomed/UNIX e-mail instead of awful vi editor 11. Powerful MAPLE software for ANALYTICAL SOLVING ON COMPUTER! 1. Those who must work with tpu editor, please use it in mornings up to -------------------------------------------------------------------- 11:00. Later biomed is too much busy - after 11:00 use pico or vi ----- editors. 2. UNIX/biomed users: DO NOT PRESS CTRL-Z when in mail, ftp or tpu. It disturbs the system. Better NOT TO PRESS CTRL-Z at all, (unless for background job.) 3. QUICK SHORT GUIDES written by Netsivi for: a) e-mail via UNIX/biomed, including both vi and pico editors b) ftp (File Transfer Protocol between computers, including binary files, and both PC's and mainframes, here and abroad) Are available from Netsivi, or can be read in the terminals room 361. 4.

Antivirus ------------- Ask Netsivi for the new version 100 of McAfee (scan) antivirus. First priority to computers that are already attacked by viruses. Second priority to labs. Third priority to single users. Last priority to those who already have version 99. Automatic antivirus (vshield) enables to immediately find the diskette with virus, but needs 40K resident memory. Be aware of possible problems, and if necessary, ask Netsivi to cancel the automatic operation of the antivirus. Do not bring children computer games to the Technion. Ask Netsivi for equivalent scan antivirus program, to be taken home and check the games there. MS-windows users - note it to Netsivi. There is a special version for MS-windows. Xterminals ---------- 7. Matlab users of mainframe computers with Xterminals: If you call Matlab: matlab -fg black -rv you will get on the screen graphs with good contrast. IF YOU GET AN ANSWER OF LICENSE PROBLEM, CLOSE THE SESSION AND OPEN A NEW SESSION, AND TRY MATLAB AGAIN. 8. Mainframe users: when finish, close: maxc (=VMS): logout and close windows. biomed (UNIX): exit or logout, and close windows. vmsa, tx, discus, and (telnet maxc): logout all the chain of computers, and close your windows. The reason: the number of allowed processes is limited in all the computers, and others want to work when you do not need the computer. 9. Printers ------------ Printers of mainframe computers: -------------------------------- A) BE CAREFUL! SEND GRAPHS TO THE PS QUEUE, AND TEXT TO THE ASCII QUEUE. ADAPT GRAPHS SHOULD BE SENT TO TK QUEUE WITH TPRINT. GRAPHS SENT TO ASCII QUEUE STALLS THE PRINTERS. When this happens, the system frees the printers automatically and periodically, but it takes time. Patience please. b) Send mail, sources, data, results to epson printer only. From biomed use zprint with option 1. Three users sent a printout of thousands blocks to the laserprinter at busy hours, and caused delays to all other innocent users. Be reasonable. c) Laserprinter: Save it for graphs, word processor prints (Tex), final prints, and for prints that are used many times (guides). DO NOT PUT IN USED PAPER. DO NOT OPEN THE PRINTER. ------------------------ ----------------------- Put paper properly in cartridge. Put cartridge properly in printer. Do not send graphs to ascii queue. Do not use it for long not final texts. d) When the printer is stalled, or when the queue is too long, one may transfer files to PC via ftp, and print with the Canon laserprinter. 360K diskette and counter are needed. The system wakes the printer once every hour if necessary, at 1:30, 2:30, etc. e) Biomed (UNIX) users: send thousands block prints with the at -- command. The at command delays execution of commands. Use at to -- -- hold heavy prints to hours when the printers are not busy. f) maxc users: use pq command to check the queue to printer. If -- your entry is on hold, you can release it, keeping the following rules: write the entry number (2 or 3 digits) I) Do not release if the printer is stalled. II) Printouts longer then 200 blocks: Release when printer is idle. III) Short printouts: Release when printer is either idle or busy. IV) The command is: set entry number/release V) Long printouts: hold with command: set entry number/hold VI) Delete unnecessary prints with: delete/entry=number PC printers in room 361: ------------------------ g) Laserprinter: Bring files on a diskette. The groups of Prof. Sideman and Rafi Beyar: ask for the Canon counters from XXXXXX. Ask Netsivi for counter when XXXXXX is absent. h) Regarding WordPerfect - Do not forget that F3 gives help on almost everything. Use that before asking questions. The first computer in room 361 has tutorial in English. Use it. During working hours the English manual is available from XXXXXX, and the Hebrew manual is available from Netsivi upon request. i) Epson PC printer: Prints of ASCII files can be made with new epson program. Option 4 gives more dark prints. 10. Friendly editor for UNIX biomed computer. Start: pico filename quit or exit: CTRL-X check spell: CTRL-T Bring file: CTRL-R and then: /u/username/path/filename Ask Netsivi to make e-mail in UNIX/biomed work with friendly pico editor, instead awful vi editor. 11. Powerful software for 386/486, named MAPLE, costs 55$ in Technion, exceeds Mathematica, Macsyma, Reduce, Mumath, etc. Includes symbolic algebra, can save time of SEARCHING in INTEGRALS TABLES, DERIVATIVES TABLES. Also SOLVES ANALYTICALLY algebraic equations and ordinary DIFFERENTIAL EQUATIONS! And much more. Uses artificial intelegence, seems science fiction, yet works fine and easily. maple, macsyma, and mathematica are ----- available free in tx UNIX computer. REDUCE is available free in VMSA. ---------------------------------- Read description of maple in room 361, or get description free from Netsivi.
