MailBITS/25-Jan-93
------------------
  Boy, that rumor about the AppleCD 300 being in short supply was a
  bum steer (financially disadvantaged, reproductively challenged
  male bovine?). Numerous people wrote to tell me that they had seen
  units around, and I have one sitting on my desk right now. Oh
  well, can't always trust those Apple rumors.


Word 5.x Not 32-bit Clean
-------------------------
  Chuck Levine wrote an apt response to our comment in TidBITS#157
  that Word 5.x-related items flagged by Compatibility Checker 2.0
  are compatible with System 7:

  "I have found that a few of the Save As translators are NOT 32-bit
  clean (namely Text with Layout) Using these translators in 32-bit
  mode will crash systems. I first found this problem with Word
  5.0a. Microsoft admitted that the problem wasn't fixed in 5.1 and
  wouldn't tell me when they planned on fixing it."

  Chuck's right about the problem with the Text with Layout
  converter, and you should also watch out for these 32-bit problems
  with Word:

* Using the WordPerfect converter in conjunction with AccessPC
  from Insignia Solutions.

* Using Alki Software's MasterWord version 1.0 (update to 1.0b for
  32-bit cleanliness).

* Using Word 4.0 and earlier (Word 4.0a is fine). If you need
  32-bit cleanliness and use Word 4.0, Microsoft will update you to
  4.0d for free.

Sounding Off
------------
  Craig O'Donnell passes on some notes on Macintosh audio as of
  Macworld Expo in San Francisco:

* I verified that the IIvx, Performa 600, and Duo 210/230 do NOT
  reproduce the right channel of a stereo sound file, for example, a
  stereo System Beep or a stereo QuickTime soundtrack. Apple's
  engineers did not know why this might be, but promised to track
  things down.

* I also verified that the AppleCD 300 can send audio tracks (from
  your favorite Elton John CD, for example) down the SCSI bus as a
  16-bit audio data stream. However, Apple engineers had no idea of
  applications for the firmware capabilities. (Essentially there are
  two problems: first, stereo audio is 10 MB per stereo minute which
  makes for large disk files; and second, the data would have to be
  sucked into an application or utility and made into a file, like
  an AIFF file, before it could be used for much of anything). This
  may, however, presage some sort of CD-ROM to DSP sound chip
  capability in future Macintoshes.

Gatekeeper 1.2.7
----------------
  by Chris Johnson, Gatekeeper author -- [e-mail]

  Gatekeeper 1.2.7 is a set of Macintosh system extensions (INITs)
  and related control panels (cdevs) that, when active (i.e. allowed
  to install themselves during the boot process), offer protection
  against attacks by all viruses known to the author at the time of
  this release.

  Gatekeeper also monitors computer activities for what are
  considered to be suspicious 'events' or 'operations,' in an
  attempt to intercept what could be variants of known viruses or
  even completely new viruses.

  Since its initial release in January of 1989, Gatekeeper has
  repeatedly demonstrated its ability to stop the spread of viruses
  which were unknown during its design. Like any anti-virus system,
  however, it cannot guarantee complete protection.

  Of course, no claims or promises are made regarding Gatekeeper's
  effectiveness or suitability, and some functions and capabilities
  of Gatekeeper are non-trivial to use and may require a careful
  reading of the documentation.

  Version 1.2.7 enhances the capabilities of, and corrects bugs in,
  version 1.2.6. Gatekeeper 1.2.7 is archived at <sumex-
  aim.stanford.edu> as /info-mac/virus/gatekeeper-127.hqx.

  [Recent discussions on the Internet indicate that the previous
  version of Gatekeeper and AutoDoubler 2.0 from Fifth Generation
  Systems tended not to agree on various matters. We use John
  Norstad's excellent and unobtrusive Disinfectant, but early
  reports indicate that Chris fixed some of the conflicts between
  the two. -Adam]


PowerBook 160 Tip
-----------------
  by Conrad Halling -- [e-mail]

  [In honor of this issue number, we present the following PowerBook
  160 tip from Conrad Halling. -Adam]

  If you set the screen to 16 grays using the Monitors control
  panel, you'll notice that the scroll bars and grow region of a
  document window draw using grays but that the title bar, including
  the go away box and the zoom box, show in black and white. On any
  other Macintosh, if you set the monitor to 16 grays (16 colors
  doesn't work), the title bar of the window draws using the grays.
  What's going on here? Why is a regular feature of the Macintosh
  interface disabled on the PowerBook 160?

  A 'WDEF' resource controls window drawing. Apple wrote a special
  WDEF resource just for the PowerBook 160 that causes the title bar
  to be drawn in black on white on a PowerBook 160 screen. This is
  because the "swimming pixel" illusion is plainly visible in a
  title bar drawn using the grays. However, as PowerBook 160 owners
  know, the six horizontal black lines in the title bar of a window
  cause annoying shadows on the screen. If you, like me, prefer your
  windows drawn in the standard manner, this tip explains how avoid
  the black and white title bars.

  The custom 'WDEF' resource is contained in the "System Enabler
  111" file in the System folder of a PowerBook 160. This 'WDEF'
  resource can be removed using ResEdit 2.1.1 (available from
  ftp.apple.com). Once you remove the custom 'WDEF' resource, the
  next time you restart, the system software will use the standard
  'WDEF' resource from the System file.


Here's how to make the change:

1)  Standard warning: use ResEdit only with a _copy_ of a
    file, never with the original. It is easy to screw things up
    so bad that you'll have to reinstall the system. Disclaimer:
    I have done this on my own PowerBook 160, but I am in no way
    responsible if you screw up and lose all your files. If you're
    not sure of what you're doing, at least back up all your files
    before you start, and have your System 7.1 installation disks
    handy. It's very unlikely that you'll need them, but just in
    case....

2)  Open the System Folder. Holding down the option key, drag
    the "System Enabler 111" file to the desktop. The Finder makes
    a copy of this file on the desktop; the original remains in
    the System folder. You will make changes only to the copy on
    the desktop.

3)  Use ResEdit to open the copy of "System Enabler 111" that
    is on the desktop.

4)  Click on the 'WDEF' line (or icon, depending on how you
    have set up the views of the resources). From the Edit menu,
    choose Cut or Clear. The 'WDEF' resource will be deleted.

5)  Save the file and close it (but don't quit ResEdit).

6)  In the File menu, choose Get File/Folder Info.... Open
    the modified copy of "System Enabler 111" that is on the
    desktop.

7)  Click the check box that unlocks the file. Then change the
    name of the file to something like "System Enabler 111
    (modified)". Click the check box that locks the file.

8)  Save the file and quit ResEdit.

9)  Create a new folder in the System folder named something
    like "Unmodified System Enabler".

10) Drag the original "System Enabler 111" file into the new
    folder.

11) Drag the modified system enabler "System Enabler 111
    (modified)" into the System folder. You have now replaced the
    original system enabler with the modified one, and you have
    cleverly saved a copy of the original system enabler where the
    system software can't see it. However, no changes will occur
    until you restart your computer (but WAIT! - don't do a
    restart just yet).

12) If you haven't already done so, use the Monitors control
    panel to set your screen to 16 grays or 16 colors.

13) Find your Disk Tools disk that came with the System 7.1
    disks. You will need this if anything goes wrong.

14) Restart your PowerBook 160. Open a window if one isn't
    already open. The title bar should now be drawn in grays.

15) If something has gone wrong (the PowerBook will not start
    if the System Enabler file is missing or grossly damaged),
    restart your PowerBook 160 using the Disk Tools disk (I told
    you to get it earlier, didn't I?). Drag the modified system
    enabler "System Enabler 111 (modified)" to the trash, and drag
    the unmodified "System Enabler 111" from the "Unmodified
    System Enabler" folder into the "System" folder. Restart your
    computer.


When Memory Isn't Enough, Try WAIS
----------------------------------
  by Mark H. Anbinder, Contributing Editor -- [e-mail]

  Even with Easy View, you may find it difficult to find those
  little tidbits of useful information you know you read in TidBITS.
  Thanks to a dedicated TidBITS reader, those of us with Internet
  access now have another option: WAIS.

  WAIS, which stands for Wide Area Information Servers, is an
  Internet-based network approach to information retrieval developed
  jointly by Thinking Machines Corporation, Apple Computer, and Dow
  Jones. It allows users to access information based on keyword
  searches; the list of items likely to be of interest is returned
  sorted in order of probable relevance to the search. Users may
  then select the documents they wish to view, and screens of text
  are sent across the network.

  Last week, Ephraim Vishniac, one of the WAIS developers at
  Thinking Machines, set up an indexed archive of TidBITS issues on
  the Internet using WAIS. This means anyone can use WAIS to
  retrieve any article or group of articles.

  If you already know how to use WAIS, just use the source
  "macintosh-tidbits.src" on cmns.think.com. Or, to search not only
  TidBITS but also the voluminous info-mac archives and
  comp.sys.mac.programmer digests, use "macintosh-news.src" instead.

  If your Mac is connected to the Internet and uses MacTCP, you can
  use Macintosh client software to access WAIS. The software may be
  FTP'd from think.com; look for WAIStation-0-63.sit.hqx. There are
  also WAIS clients available for a variety of other platforms such
  as DOS, Sun, and VMS. Check on think.com, or, if you're in Europe,
  check first on nic.funet.fi in the directory
  /pub/networking/service/wais. Alternately look for the
  comp.infosystems.wais Frequently Asked Questions list that
  specifies where each version may be located.

  If you don't have a Mac on the Internet but you do have access to
  an Internet-connected computer that offers telnet services, you
  can use the screen-based WAIS (swais) service along with a VT100
  emulator. Just telnet to quake.think.com and enter the username
  wais (all lowercase) at the login: prompt. This swais service
  isn't pretty but works for those of us who don't have real
  Internet connections for our Macs.

  Either way, use the source document "macintosh-tidbits.src"
  located on cmns.think.com, and specify one or more keywords that
  will enable the WAIS server to find the information buried in
  TidBITS that you want to see.

  If you're interested in more details about WAIS, browse through
  the files available in the /wais directory on think.com via FTP,
  or skim the articles in the comp.infosystems.wais newsgroup.

    comp.infosystems.wais FAQ


Virtual 3.0
-----------
  At Macworld, Connectix showed their newly-released version 3.0 of
  Virtual, which implements virtual memory on the Mac. Although
  Connectix has had versions of Virtual 3.0 running on various
  accelerators that are incompatible with System 7's built-in VM
  (virtual memory), the generic version of Virtual 3.0 had been
  plagued by delays.

  Now that it's out, why would you want it? Frankly, because it
  works the way virtual memory should work, quickly and without
  using a ton of disk space. I've never used VM seriously because
  like many people, I'm constantly low on disk space. If you have 8
  MB of RAM and wish to add 5 MB to that for a total of 13 MB, you
  have to have a full 13 MB of free disk space for the swap file
  that holds the contents of memory that won't fit in the real RAM.
  That's a waste of disk space. Virtual 3.0 can work like that too,
  but it also has a DiskSaver mode that uses the amount of disk
  space equal to the amount of memory you request. In our example
  above, where you have 8 MB of real RAM and want 5 MB more of
  virtual memory, Virtual 3.0 can give you that total of 13 MB and
  use only 5 MB of disk space.

  The other reason to use Virtual 3.0 over Apple's VM is that even
  in DiskSaver mode, Virtual is faster. In the tests I saw on
  identical PowerBook 170s, Virtual 3.0 was noticeably faster. I
  hope to do a few simple speed tests (although it's a major pain
  for me to turn on VM since I seldom have much free disk space)
  once I have Virtual 3.0 to evaluate. I was warned that some
  benchmark programs are fooled by Apple's patches so the results
  appear faster than real RAM. The safe route for benchmarking
  virtual memory, then, is the low-tech stopwatch.

  Those of you trying to use virtual memory on a PowerBook know what
  a battery hog VM is. Virtual 3.0 avoids this problem by turning
  off when the PowerBook is running on battery power (I hope there's
  an override for this, just in case).

  My conclusion is that if you rely on virtual memory, and
  especially if you can't easily free up lots of disk space, you
  will like Virtual 3.0. If you only turn virtual memory on
  occasionally and you have lots of free space on that gigabyte
  drive, it's probably not worth the money for Virtual. And of
  course, just like with compression programs, if possible, the best
  alternative is to drop more SIMMs in your Mac. Virtual 3.0 lists
  for $99 and should be readily available from dealers and mail
  order vendors. Registered owners of Connectix's CPU can buy
  Virtual 3.0 for $19 (plus shipping and tax where applicable) by
  calling them and asking nicely.

Species, Genus, Phyla
---------------------
  One of the more interesting previews of programs that I saw at
  Macworld was of Mainstay's new object-oriented database, Phyla.
  Unlike traditional databases, Phyla is neither flat-file (with a
  simple one-to-one relationship between all types of data, such as
  Person, Father, and Mother) nor precisely relational (with a
  one-to-many relationship between data, such as Company and Phone
  Numbers), although you can accomplish most everything in Phyla
  that you could in a relational database. The basic principle
  underlying Phyla is that of object-orientation; everything is an
  object, and those objects can be easily related. I'm no expert in
  databases, particularly relational databases, although I have
  worked with Double Helix (now called Helix Express) in the past.

  Given that disclaimer, you can create classes of objects like the
  people in a department or the computers they use that are
  equivalent to Double Helix's relations. Once you have classes of
  objects, you define what Phyla more colloquially calls a relation,
  the relationship between two classes of objects. In our example,
  you could define a "Uses (Hardware)" relation and the reverse,
  "(Hardware) Is Used By," because relationships between classes of
  objects go both ways between the class of "Staff Members" and the
  class of "Department Macs." At any time it's trivial to create
  another class, say "Licensed Software" and the two associated
  relations to "Department Macs," namely "Is Installed On" and "Has
  On Hard Disk." Similarly, you could then relate "Licensed
  Software" to "Staff Members" with "Uses (Software)" and
  "(Software) Is Used By."

  At this point we have three interrelated classes of objects, and
  Phyla makes quick queries easy, such as what sort of Mac does Jill
  use, what software is on it, and what does Jill actually use. The
  standard class view, for say, "Staff Member" looks remarkably like
  a Finder 7 outline view, and flipping the triangle next to Jill's
  name displays the two relations to that class, "Uses (Hardware)"
  and "Uses (Software)." Each of those two entries in the outline
  also has a triangle, and flipping them down reveals the data in
  the other object classes that match. Initially none will, of
  course, because we haven't defined any common field, such as
  "Staff Member," as you would do in a relational database. Instead,
  in Phyla you merely open another object class window, for
  "Department Macs," for instance, and then drag an entry or two
  over to Jill in the other outline, like moving files in the
  Finder's outline view.

  Since we have already defined the ways these two classes of
  objects relate, dragging a Mac into Jill's outline entry
  establishes that link both ways, so Jill now shows up in the
  outline view underneath that model of Mac. So if we gave Jill a
  Quadra 950, the "(Hardware) Is Used By" relation under the Quadra
  950's entry in the "Department Macs" outline will also contain
  Jill. You can build databases by thinking out the relationships
  among classes of objects in English, and then implementing them in
  a relatively natural way.

  You'll have to look at Phyla to make sure you understand what I've
  said, but if anything, I found it more understandable than other
  databases I've used. I did ask a couple of questions specific to a
  database project I'm thinking about (an Ultimate Kitchen Mac
  database that does more than just database things). First among
  these was line items, such as you would find in an recipe. Line
  items can be hard because you have a one-to-many relationship
  between the recipe and the ingredients, but you never know how
  many ingredients a recipe will have. The Mainstay rep showed me a
  sample invoice database that handled line items well. My second
  quirky request was for the capability to create a timer, so if a
  recipe has a cooking time, I'd like to be able to click a single
  button and have a timer start up and count down, warning me with
  an appropriate sound. The rep claimed that Phyla could do just
  that, but couldn't find the job-tracking database that he thought
  would demonstrate Phyla's ability.

  Overall, I was impressed, but although Phyla seemed to do most
  everything I could think of, and although it appeared to have
  flexible forms for entering and displaying data, the proof will be
  in the data pudding, and it might appear this spring or summer.

Booth Bimbos
------------
  A number of people wrote in regard to our articles on booth bimbos
  and CD-ROM pornography. Several suggested that booth bimbos are
  used to attract people to a booth, much like a flashy
  demonstration or clever freebies. I agree that booth bimbos act as
  an attractant for some, but for others, booth bimbos make for an
  embarrassing and potentially offensive situation. Furthermore,
  talking to them is always so depressing. What do you say, knowing
  that the person has the technical background of Cheez Wiz? "So
  hey, nice teeth you've got there..."

  If a company doesn't have the guts to laugh at itself with a
  blow-up booth bimbo, it should at least spring for good freebies.
  Clever and durable giveaways provide lasting exposure, and people
  do wear t-shirts if they like the company or program.

  Alternately, try food. As Linda Iroff, a friend at Oberlin
  College, writes, "The scent of fresh-baked chocolate chip cookies
  drew me to Contour Designs, tucked in a corner of the big hall. I
  will sit though a WordPerfect demo just for one of those mint
  truffles and a hat. I filled out an application for a free
  subscription to a new magazine to get some popcorn. And I will
  listen to anyone's spiel if I think I can get a free t-shirt out
  of it. These freebies aren't going to make me buy their products,
  but it does get me to look at what they have to offer. Anyway, I
  guess some people will be drawn into a booth by a bimbo. I,
  however, recommend cookies."

That Pornography Thing
----------------------
  We touched a few nerves with our article on CD-ROM pornography.
  The most well-reasoned and rational letter came from Phil Ryan of
  Melbourne, Australia. Read Phil's letter, and then we'll offer
  additional thoughts on why we wrote the article and the overall
  subject.


Phil Ryan writes:
  Before anyone mentions 'censorship,' I want to register my
  objection to pornography (it's a free world). I am a part-time law
  student as well as a computer nutcase (i.e. Physics Ph.D.). In
  1992 I enrolled in a course called 'Feminist Legal Theory' -
  partly because I wanted to find out about feminism, partly because
  it was the only class that I could get to while working full-time.

  During the course we examined various things, including
  pornography. When we first brought it up, most students expressed
  the opinion that porn is 'just a bit of fluff, and besides, women
  make money out of it.' However, as we looked more closely into the
  issue, we saw how many women are (1) injured in the production of
  porn - like prostitutes they usually are not doing it out of 'free
  choice,' (2) offended by pornographic images - particularly
  violent ones, and (3) generally treated as 'things,' a 'piece of
  meat,' by the pornography industry. We began to realize that porn
  is more insidious than people realize.

  I, and most of the modern, feminist anti-porn campaigners, do not
  criticize this industry from the point of view that it 'corrupts
  the populace' (which is, by the way, the way that most laws in
  Western countries are framed). Rather, we criticize the industry
  from the point of view that real women are injured and oppressed
  in real ways in order to produce this stuff. Other than Madonna,
  the vast majority of women used in the pornography industry are
  not the major beneficiaries of the money generated.

  My main references on this are Catherine Mackinnon and Andrea
  Dworkin, American anti-porn campaigners. They started out being
  anti-rape campaigners and thought too that porn wasn't a big
  problem. However, they became deluged with requests for assistance
  from refugees of the now $10 billion or more porn industry.

  I object to pornography, and would rather not see it mentioned
  when criticism of the pornography industry's methods is not also
  mentioned.


Some additional thoughts
  Thanks, Phil. It is a free world, at least in some places, and
  thanks for pointing that out. Freedom cuts both ways.

  This is obviously a sensitive issue and we apologize for any
  offense any of our readers may have taken. However, we do not
  apologize for publishing the article. Avoiding any arguments based
  on good or evil, we found the existence of so many pornographic
  CD-ROMs astonishing, and as such, fodder for TidBITS. I wrote in
  the context of the Macintosh and technology and provided contact
  information. Think about that. Sure, you could immediately use the
  phone numbers to order a CD-ROM and drool into your keyboard. But,
  that information also gives you the power to call and state your
  complaints. Maybe the vendors would learn something from you, or
  maybe you would learn something from them. Perhaps the most
  important tenet underlying TidBITS is that of communication. We
  firmly believe that only through communication can global problems
  be solved, and although we normally stick to our tiny niche,
  larger subjects occasionally impinge on our Macintosh-based tunnel
  vision.

  Pornography is just such a topic, and we at TidBITS have devoted
  some serious thought to it in the past week, responding to your
  letters and trying to decide how we feel. Phil's excellent letter
  prompted much of the thought, and we agree with his final
  statement about needing to balance the issue with criticisms of
  the pornography industry's methods. I hope his letter achieves
  that for others as well.

  We offer a few of our thoughts, merely as something for you to
  mull over, agree with, disagree with, or toss out as the words of
  crackpots. In reading Phil's letter, I was struck by the
  possibility left open for "good" pornography that does not injure
  women. Apart from subjective evaluations of what is or is not
  offensive, and Mark has more on that subject, many objections
  could be met by union-style safeguards in terms of fair pay,
  working conditions, and so on. Such "good" pornography would then
  have a marketing advantage much like that enjoyed by the tuna fish
  companies that take pains not to harm dolphins. One hopes that
  market pressure would then force exploitative and injurious
  companies out of business. In terms of worker treatment, the
  pornography industry doesn't differ significantly from any other.
  People can be mistreated in any field, including government, as
  recent sexual harassment cases show.

  In relation to whether or not pornography is offensive, Mark
  Anbinder writes, "If we allow one person or group of people to
  impose his or her concept of morality or acceptability on another
  person or group of people, we begin to dismantle the very
  structure of our freedom. It is vitally important that we do not
  allow anyone, least of all ourselves, to quench that freedom." To
  expand that sentiment slightly, consider quickly the fact that
  what we feel is normal and healthy may seriously offend someone
  from another culture. Let each person be offended in his or her
  own way but never decree that others share that feeling.

  This discussion alone could easily overwhelm our weekly space, so
  we'll leave it in the future to other, more appropriate, forums.
  Feel free to keep thinking and sending us your comments; we'll try
  to reply within the limits of our wrists. 'Nuff said.
