Sisyphus Difficulties …

Herein lies information to help you successfully use my webpages. Perhaps you have a suggestion on how I could improve these pages?

There is an Online viewer for PDF, PostScript and Word. Postscript files often have a .ps extension. This site does automatic GZIP [the .gz extension] decompression.

I do not know of an online reader of .dvi [which stands for DeVice Independent -the output from the TeX typesetting language.] files; if you find one, please let me know.

… with Browsing or Printing

[These next paragraphs are out-of-date.]
The links in my pages go to either HTML files, text files or postscript files. [Webpages of old, old courses may have links to dvi files. However, these are not needed by my current students. A few of my old files are compressed, by gzip, and will have a .gz extension.
    Perhaps your browser is having difficulties with the .ps or .gz format. Perhaps you are running a browser on a non-Unix machine. Alas, I am unfamiliar with such machines.
    Fortunately, there are several documents that may help you help yourself.
Printing postscript files at The University of Florida (UF) Postscript icon
Marston Science Library: Here is [a modification] what I (Prof. JLF King) did on 07Oct1999.
    On one of the computers in front of the circulation desk, I pull up Netscape (NS). When I clicked on a link to a postscript (ps) file, NS invokes a ps viewer called GSview. Its default magnification is huge[1]. The math symbols are readable, although grainy -but it prints perfectly.

    To print:    From the GSview  File menu, Select Print. A dialog box[2] pops up. Make sure the box for PostScript Printer is checked, then click Ok, and the dialog evaporates.
    A new box pops up, asking for a username; I type something here that I will remember, something unlikely to be used by anyone else.
    To retrieve the document, I walk to the bank of printers by the reference desk and insert a copier card into the maw[3] of a card-reader, next to a monitor. The monitor asks me to type the username that I just used. It then displays all print-jobs under that username. I click on the job that I wish, and the printer prints it immediately. The ps prints flawlessly.


`GSview' is apparently a free ps-viewing program for Windows. You might want to install it on your home system, if you run Windows. For UNIX, use `ghostview'.

[1] To reduce the image size and make more text appear in the window, click on the lefthand button showing a circle with a minus-sign in it.

[2] I used the default 300x300 resolution. I used the default printer (called Inkjet).

[3] The library charged 10cents per page. On my webpage, however, the number of ps pages that you would want to print during the entire semester will probably set you back no more than 3 bucks; negligible. And the convenience of Marston Science Library is hard to beat.

I presume that the above discussion also applies to the computers at Library West.
