One trick I've learned (the hard way) for reducing the number of bugs in
my JavaScript is to make use of any and all tools and techniques for
cutting down on the amount of typing I have to do. Kas unveils new 'secret weapon' against typos.
Kas Thomas
Kas presents an exercise on how to set up an image map in a PDF file and couple it to a Perl script running on a server, creating an RGB color picker as an example.
Kas Thomas
Kas is always looking for ways to improve his -- and your -- script-writing skills and practices. He's got another shortcut that will cut down on your keystroking, and thus lessen the chance for the dreaded Script Typo.

The watch() method, although present in Acrobat JavaScript, doesn't work correctly (at least under Acrobat 4.05 for Mac). It causes the property that's being "watched" to become undefined.
Kas Thomas
Kas shares with us an efficient way of popping windows-based messages from within PDF documents.
Kas Thomas
The (disturbing) subject of bugs in Acrobat, and points out one problem that could very well cause you grief if you ever try to do any numerical operations on character values in strings.
Kas Thomas
Kas tells you how to get rid of the object reference parameter "this", the advantages and drawbacks of using it in various contexts.

With the corporate enterprise as a key market Adobe had in mind during the development of Acrobat 5.0, considerable effort went into expanding the product's capabilities for online workgroup collaborations. Last month The Seybold Report took a close look at the pros and cons, testing the setup and use of WebDAV (Web Document Authoring and Versioning) and PDF. We're re-publishing their detailed review with permission; the article is also available as a seven-page PDF.

Although
we did not test any Microsoft applications, they will have a significant
impact on the use of online PDFs, especially in the corporate enterprise.
Since the majority of Acrobat users are not involved in traditional graphic
arts but are part of law firms, insurance agencies, government bodies
and so on, we can expect Microsoft's and Adobe's Web and collaboration
tools to develop a decidedly "corporate" aspect.

When Acrobat 5 was released, online digital signatures were presented as an
integral part of a collaborative PDF workflow. We assumed, erroneously,
that these would be handled in the same manner as online comments -- via
shared folders or WebDAV. Instead, we learned that online signatures had
to be implemented in a more cumbersome way, which unfortunately we were
unable to test.

In general, a WebDAV server has modest hardware requirements. A Pentium
or PowerPC-based system with at least 128 MB RAM and 4GB disk space is
sufficient for the Acrobat workflow we tested. WebDAV can be installed
on most modern server operating systems, including Windows NT Server,
Windows 2000 Professional, OS X and Linux. An optimum configuration was
achieved, in our opinion, was achieved by using Red Hat Linux, Apache
and the WebDAV Extension.

Before
we can share PDF files on the Web, we must first find a way to get them
there. Despite promises in numerous marketing brochures, putting data
online is not often an easy matter. Absent any support from CGI scripts,
the online data must usually be uploaded to the Web server using an FTP
application; the normal browser will not suffice.
Thomas Merz's book describes the production of efficient PDF documents.
View or download Thinking in Java (2nd Ed & 3rd Ed, beta). "What a magnificent book! It's got just the right balance between code and discussion, and the exercises are good. I've done all of them to the end of Ch. 10, and I feel like I'm making good progress with Java."
