TidBITS#241/29-Aug-94
=====================

Fat binary versions of programs get more votes from readers in
   this issue, and we pass on the announcement of the latest After
   Dark Module Programming Contest in which you don't even have
   to be a programmer to compete. Those without expandable Macs
   may be interested in PowerR's video solutions, and we look at
   Farallon's Timbuktu Pro, which enables you to control a
   Macintosh remotely over an AppleTalk network, via ARA, or
   over the Internet.

MailBITS/29-Aug-94
------------------
  The quote of the week goes to Bill Gates, who was paraphrased in a
  MacWEEK article in the 22-Aug-94 issue as saying that no company
  has produced more titles for Power Macs [than Microsoft]. This is
  indeed true, but only on the planet Stiltspah, where Power Mac-
  native versions of Word, Excel, PowerPoint, Project, and FoxPro
  have been shipping for over three years. [ACE]


**LISTSERV Reminder** -- Just as a quick reminder, you can
  subscribe to TidBITS via an Internet mailing list (yes, this works
  for people on America Online, CompuServe, and so on). To
  subscribe, send email to <[e-mail]> with this
  line in the body of the mailfile:

SUBSCRIBE TIDBITS your full name

  The corollary to this piece of information is that to change your
  subscription from one email address to another, first send the
  SIGNOFF TIDBITS command to <[e-mail]> from your
  old account, and then subscribe again using the instructions above
  from your new account. In other words, there is no "change
  subscription" command. If it's impossible for you to sign off from
  your old account, I can do it for you, but frankly, if you can
  work with the automated LISTSERV program, I'm sure it enjoys the
  task more than I do. [ACE]


**Submitting to TidBITS** -- I just ran into a situation that I
  feel bad about, and I hope this note might help matters in the
  future. Someone sent me email about a product he had used and
  liked, and several issues later, Mark independently wrote an
  article about the same product. This guy justifiably felt a little
  miffed that we'd ignored him, and I don't like hurting people's
  feelings. The problem is that I get a lot of mail, often well over
  a hundred messages a day via the Internet. I also get mail via
  CompuServe and America Online (but would prefer not to - please
  use the Internet gateways if you can) that I check less
  frequently. If someone sends me a message telling me about a new
  product, or some new Internet resource for Mac users, or something
  like that, it's likely to be filed away for future reference. We
  are currently talking about new ways of storing away all the
  information that comes in via email, but for now, we're more
  likely to use information that already resembles a MailBIT or
  article (it helps especially if you check both sides of any issues
  and include contact information and especially email addresses).
  It's also a good idea to ask first about article ideas, just to
  make sure there's no duplication of effort. [ACE]


**Display Card 24AC** software is now available for Power Mac
  users; version 1.2 of the video card driver supports Power
  Macintosh. Version 1.1 was compatible with Power Macintosh
  hardware, but ran slowly because it was 680x0 code running in
  emulation. The update can be found on AppleLink, eWorld, and other
  online services. [MHA]

**Joshua Weinberg** <[e-mail]> writes to say that he
  purchased System 7.5 for $99 last Saturday at CompUSA in New York
  City. Although he noted that the CompUSA folks said they had
  gotten System 7.5 in ten days early, it sounds like it will be
  available for the masses soon. Talk to your friendly local dealer
  or other purveyor of Macintosh software. You might also ask your
  user group - we've heard rumblings about user groups selling
  System 7.5 cheaper than the stores, reportedly for $49. [ACE]


Fat Binary Comments
-------------------
  by Adam C. Engst <[e-mail]>

  Many people wrote in to comment on my article about fat binaries
  in TidBITS-240_, in the process raising a few issues that I hadn't
  previously considered.


**Peter Lewis** <[e-mail]> notes:
  The Umich archive people said they don't want two different
  versions at <mac.archive.umich.edu>, so a fat binary is pretty
  much the only choice. It's a slight pain since it makes
  downloading take longer (and cost more), but I see their point.


**Chris Meyer** <[e-mail]> writes:
  We have a pair of Quadra 950s with Apple Power Mac upgrade cards
  in them and often switch between PowerPC and 68040 modes,
  depending on what we want to do and whether or not we have native
  tools.

  We dislike needing two versions of each program for the two modes
  our Quadras can run in. Sometimes double-clicking on a document
  opens the wrong version (which means you either run very slow, or
  you crash). Some plug-ins even come in two versions, requiring two
  different plug-in folders. And installers are often stupid in
  their attempt to be smart - we want both versions installed, not
  the one that matches the current CPU mode. In the latest version
  of Elastic Reality, which uses the VICE installer, I went to
  custom and checked both versions - and it still only installed the
  040 versions. Sigh.


**Andrew Zmolek** <[e-mail]> echoes Chris's comments:
  Don't forget that some of us have PowerPC upgrade cards and want
  to have fat binaries of all our favorite programs. If I can get a
  fat binary, then I know I'm always running as fast as I can for
  either processor.

  I have a big beef with companies like Claris and WordPerfect that
  refuse to provide fat binaries. This forces me to install both
  versions and I have to use drag & drop to ensure that I open my
  files with the correct version.

  WordPerfect 3.0 can be "fattened" by pasting the code resources
  from the 68K version into the PowerPC version, but ClarisWorks
  can't. It has different resources between the two versions, so
  this trick won't work. Moreover, ClarisWorks complains that it's
  been modified. Speaking with the Claris folks made it clear to me
  that they care nothing about making a fat binary version, even
  though that's what they promised when I ordered the PowerPC-native
  upgrade several months ago.

  There are other legitimate reasons to want fat binaries.
  Applications that reside on fileservers are easier to use and
  maintain if they're fat. Shareware and freeware can be passed on
  to other users without regard to the type of Mac they'll be run
  on.


**Mike Tippets** <[e-mail]> writes:
  In preparing our native version of WordPerfect 3.0, which shipped
  on 14-Mar-94, we heavily researched the fat binary option. We
  determined as you concluded in your article that a "smart
  installer" was the better solution. However, as you mentioned at
  the end of the article, it is also a nice option to have a fat
  binary choice. Our large site customers have since requested that
  we give them a fat binary option in the installer. The reason for
  this request is that many times they want to install one copy of
  the application on a server and let Power Macs and 68K Macs access
  the same location for their application. Having the fat binary
  option gives them this choice. We are adding a fat binary option
  in the custom part of our installer for WordPerfect 3.1 in
  response to this request.


**George Suttle** <[e-mail]> adds:
  The fat binary issues is becoming problematic for me. I took my
  old Classic II into my office when I got my new Power Mac 7100.
  Naturally I want programs optimized for the Power Mac, but
  programs like PageMaker 5.0 that only include PowerPC code prevent
  me from using them at work. Some license agreements permit
  installation on home/office machines so long as there isn't
  simultaneous use, but that's undermined by Aldus's practice of
  dual releases. On the other hand, I don't want to spare room on my
  crammed-up Classic II drive for redundant code. So I would come
  down on the side of smart installers.


After Dark Contest
------------------
  by Tonya Engst <[e-mail]>

  The deadline for this year's Berkeley Systems After Dark module
  contest is 14-Oct-94, and the prizes look pretty good. The contest
  has four categories and only one requires you to know anything
  about programming.

  In the Programming category you must program either a Macintosh
  module or a Windows module. For the Artist category you must
  create the computer graphics for a module and describe how it
  would work visually. To enter the Kids category, you must be 12
  years old or younger and submit drawings and a written description
  of the module. Finally, the Classroom category works much like the
  Kids category, but it's for a collaboration among children in a
  classroom (grades K-6).

  For the Programmer and Artist categories, one grand prize winner
  receives the hefty sum of $10,000, and runner-ups receive assorted
  computer equipment and software. The first place winner in the
  Kids category gets a Performa for personal use; the first place
  winners in the Classroom category win four Performas for their
  school. To get an entry form, look in the Berkeley Systems forum
  on America Online or CompuServe, call Berkeley Systems at 510/540-
  5535 (ask for extension 600 to reach the contest hotline), or look
  on the Internet using a Web browser at either:

http://proper.com:70/1/mac/sponsors/BerkeleySystems
ftp://ftp.att.com/pub/afterdark/index.html

  This particular FTP site also has a large collection of After Dark
  modules if you want more.

  Also, aspiring After Dark module programmers can hook into the
  module developer community by subscribing to a mailing list for

Video Without Holes
-------------------
  by Mark H. Anbinder, News Editor <[e-mail]>
     Director of Technical Services, Baka Industries Inc.

  By early 1992, there were multiple video output options for the
  suddenly popular PowerBooks. Companies like Envisio took advantage
  of this or that internal connection to provide external video
  support to connect a monitor or LCD projection panel to the
  PowerBooks. Today, most of Apple's current PowerBooks support
  video output, but for those that don't, as well as for a variety
  of other video-less Macs, a company called PowerR has a solution.

  Ranging from $129 to $299 retail, PowerR's products provide video
  output for Macintosh models such as the Color Classic and LC or
  Performa 575, or old all-in-one Macs like the Plus, SE, and SE/30,
  and of course those first-generation 140, 145, and 170 model
  PowerBooks, without the need for cutting out strips of plastic or
  soldering connections.

  PowerR's Presenter and other video adapter devices connect to the
  Macs' internal video connectors, and take advantage of existing
  holes or slots in the outer case to bring a VGA-compatible video
  port out where it can do good. The connector for the PowerBook
  140, 145, and 170 models, for example, piggy-backs on the internal
  port that connects the top and bottom halves of the PowerBook and
  carries the video signal. The signal is split and send out through
  the connector, which is wedged through the case's existing
  opening. Such an approach leaves the PowerBook's internal slot
  free (the Envisio adapters used the memory slot) and avoids
  software conflict issues entirely. With a suggested retail price
  of $299, these are the most expensive of PowerR's video adapters,
  but early-model PowerBook owners at least have a video option
  again.

  The Color Classic and LC 575 cases are even easier; they sport
  those traditional vertical air slots Apple is so fond of designing
  into its plastic cases. The leads for these video adapters go
  right through these slots. PowerR's adapter is correspondingly
  simpler, and sells for only $129 for these machines.

  Since the vast majority of LCD projection panels (I'm tempted to
  say "all") have a VGA video port, the compact PowerBook unit from
  PowerR saves room by offering only a VGA connector. Most of the
  other PowerR models have both VGA and standard Apple DB-15
  connectors. All look well-assembled and solid.

  Among their other products, PowerR offers an adapter to LCD panels
  for Macs that already have DB-15 video output; for computers with
  NTSC output such as Atari, Commodore, and Apple II systems; and
  for low-end IBM systems.

  PowerR's products are not engineering miracles or stunning
  innovations. It's all been done before. But PowerR has the
  innovative nerve to provide stunning support for old computers no
  one else will touch.

Timbuktu Pro
------------
  by Adam C. Engst <[e-mail]>

  [Excerpted from Internet Starter Kit for Macintosh, 2nd edition.]

  As time goes by in the Internet world, software that once ran
  solely on local area networks such as LocalTalk or Ethernet is
  migrating to the Internet. Often, it's not much of a chore to
  support the Internet - it's simply another network protocol, after
  all. However, with so many people accessing the Internet via SLIP
  or PPP and a relatively slow modem, the challenge to programmers
  becomes more serious. How can they provide adequate performance
  with a program designed to work over a network many times faster
  than the average modem?

  The network wizards at Farallon faced this problem with Timbuktu
  Pro, a recent release of their long-standing Timbuktu application
  for controlling Macs and PCs from afar. Let me explain the idea
  behind Timbuktu a little more before I get into the version that
  now works over the Internet, because once you see what Timbuktu
  does, you'll better understand why supporting Internet connections
  was such a coup.

  Networking the Macintosh has always been easy, thanks to Apple's
  foresight in including network hardware in every Mac, and (since
  System 7) including the software necessary to create a small
  network complete with servers and clients. Because of this,
  relatively wide-flung Macintosh networks sprang up quickly, making
  it difficult for a network administrator to physically visit each
  Mac that might be having a problem or simply need to be checked
  on. Farallon solved this problem with Timbuktu, an application
  that enabled the network administrator (or anyone else running the
  program, for that matter), to work on a host Mac somewhere else on
  the network just as though it were on the administrator's desk.
  Timbuktu became especially popular in large corporations because
  Sam on the 15th floor could call down to the help desk when he had
  a problem, and the help desk could not only watch onscreen what
  Sam did, it could also perform the task correctly, so Sam could
  see how to do it next time. All without some peon dashing up
  flights of stairs .

  This was all fine and nice, and Timbuktu became popular. Farallon
  added the capability for Timbuktu to control PC-compatibles
  running Windows, and continually increased Timbuktu's speed, since
  transferring all that data over a network was poky, to say the
  least. Then, in late 1993, Farallon released Timbuktu Pro for the
  Macintosh. Timbuktu Pro increased the speed of execution, added
  support for Apple Remote Access (ARA) and probably fixed a few
  bugs, but most interestingly, it added support for TCP/IP networks
  - in other words, the Internet.

  All of a sudden, not only can you observe or control a Mac on your
  network, but you can observe or control an Internet-connected
  Macintosh running Timbuktu anywhere in the world. Before you start
  shaking in your shoes about the security implications, let me
  assure you that Timbuktu has strong security features, and unless
  you allow others to control your Mac, they won't be able to do so.
  Same goes for observation; it's completely under the user's
  control, so there are no security or privacy implications that you
  cannot control yourself. One last thing - you must have two copies
  of Timbuktu to use it. When you buy it, you get both the client
  and the server, and I know of only one public Macintosh running
  Timbuktu, a demo machine at Farallon.


**Installation and Usage** -- Installation of Timbuktu is handled
  by the Apple Installer and is thus relatively straightforward.
  After you finish and restart, you should see a Timbuktu icon
  appear as the Mac starts up. This icon comes from Timbuktu
  Extension in your Extensions folder. The Timbuktu application
  appears in your Apple Menu Items folder, and the Timbuktu Sender
  application shows up on your desktop. If you use System 7 Pro, a
  Timbuktu Catalogs Extension goes in your Extensions folder as
  well.

  You use the Timbuktu application, which you launch either from the
  menu that the extension creates on the right side of your menu
  bar, or by double-clicking the application, for one of four tasks:
  observing a host Mac, controlling a host Mac, sending files to a
  host Mac, or exchanging files both ways with a host Mac. When
  launched, Timbuktu Pro presents a New Connection window and a User
  Access window, the latter of which enables you to see and control
  what sort of access others have to your Mac.

  The New Connection window has a pop-up menu with two choices,
  AppleTalk and TCP/IP. I'll concentrate on the TCP/IP setting,
  since that's the most interesting method of access and it's
  basically the same for AppleTalk anyway.

  Farallon has made a Macintosh running Timbuktu available as a demo
  machine, and Farallon cleverly placed that demo machine's name and
  IP number into the New Connection window when the TCP/IP option is
  selected. So, typing <timbuktu.farallon.com> into the IP address
  field and clicking on the Control button enables you to control
  that remote Macintosh. Because <timbuktu.farallon.com> is a public
  Mac that Farallon wants people to use, the program doesn't ask for
  a username or password. Most Macs would have security features in
  place to prevent unsavory characters from riffling through private
  files.

  Once connected to <timbuktu.farallon.com>, a window appears that
  represents the host Mac. In fact, it looks just like a normal
  Macintosh screen. When the mouse cursor is in that window, your
  keyboard works for the host Mac, and you can do anything there
  that you can do on any other Mac, except touch it.

  Needless to say, the screen redraws slowly, since Timbuktu must
  transfer all the screen redraw information over the Internet
  connection, and if that's a modem, it takes time. You won't work
  on a machine like that all day long, but it's fine for basic
  troubleshooting and server control.

  Farallon cleverly set up their demo machine to encourage you to
  check out their files, including tech support files about
  Timbuktu, Disinfectant (only slightly out of date), a demo version
  of Replica (another of their programs), and a folder entitled
  "Leave your comments here!" To exchange files, you click on the
  small icon of a folder with a double-headed arrow on the left-hand
  side of the Timbuktu window. Timbuktu asks for your username and
  password (I just told it I was a guest) and brings up the Exchange
  Files window.

  The Exchange Files window works much like the Font/DA Mover (not
  that many people necessarily remember the Font/DA Mover, which
  hasn't been necessary since System 6 days). You navigate through
  the hierarchy on either the guest or the host Mac, and by Shift-
  or Command-clicking on items, select files to transfer. Clicking
  the Copy button makes files copy in the direction of the arrows.

  That's about it for basic usage in Timbuktu Pro as a guest. If you
  want to be a host, your Mac must be connected to the Internet via
  MacTCP and either SLIP or PPP or a network. You should use Define
  Users from the Setup menu to create users with specific privileges
  before turning on access, because if you provide full access to
  your Mac, nothing prevents someone from wreaking havoc on your
  system. After you've defined some users and properly set up Guest
  access if you wish to use it, selecting TCP/IP User Access from
  the Timbuktu Extension's menu in the menu bar, or clicking the On
  radio button for TCP/IP User Access in the User Access window of
  the Timbuktu application makes your Mac available as a host.

  Needless to say, for someone to connect to you, they must know
  either your Mac's IP name or IP number, so if you use a Server-
  addressed account and don't have a dedicated IP name, you must
  somehow communicate the proper IP number to your guest.


**Special Features** -- In many ways, Timbuktu sports no special
  features. After all, what it does is astonishing enough - the
  concept of using another Macintosh over the Internet is extremely
  cool. However, the attention to detail is high, and little things
  such as screen sharing in color without a major speed hit is
  impressive.

  Timbuktu has a number of buttons along the side of the Timbuktu
  main window. These buttons enable you to toggle between
  controlling the remote Mac and merely observing it, send or
  exchange files, transfer clipboards back and forth, take a
  screenshot of the remote screen, switch monitors on a multiple
  monitor host, and toggle between color and grayscale.

  The Timbuktu Sender application simplifies sending files to host
  Macs - you can even send multiple files to multiple hosts at the
  same time by dragging one or more files onto Timbuktu Sender and,
  when it asks, providing the IP address of each  recipient.
  Timbuktu then sends the files to each of the hosts in turn,
  placing the files in a folder with your name on it inside another
  folder called (by default) Files Received. It's a bit like
  broadcasting.

  If you regularly connect to the same Mac, you can use connection
  documents to simplify the process. Launching a specific connection
  document connects you to the specified host Mac. It's actually
  kind of eerie - open a document and suddenly you're using or
  watching another Mac in a window on your screen.

  Finally, Timbuktu keeps an activity log that tracks what everyone
  does on your Mac, which can be handy for seeing who has been
  peeking in. It also tracks when Timbuktu itself loads or shuts
  down, which corresponds closely with when your Mac restarts. It's
  interesting to see how often you restart, if nothing else.


**Overall Evaluation** -- As you may have gathered, I'm rather
  impressed with Timbuktu Pro. I'd never used it until the Internet
  version, but a friend of mine swears by it for controlling his
  Windows machine on his local area network. Most of my experience
  has come in administrating a Gopher server on a Macintosh SE/30
  running Peter Lewis's FTPd. The Macintosh lives elsewhere, but
  it's directly connected to the Internet, and I can check in at any
  time by simply connecting via SLIP or PPP and launching my
  Timbuktu Pro connection document.

  Timbuktu Pro's worst problem is that using it is not as fast as
  using a Mac normally, especially when connecting over the Internet
  via modem. The mouse is jerky, menus drop slowly, and highlighting
  a menu item can take forever. You wouldn't use a host Mac via
  Timbuktu Pro for daily work over a modem connection to the
  Internet. Nonetheless, most actions are fast enough to be worth
  the trade-off, and just because the screen draws slowly doesn't
  mean the host Mac is operating slowly. Programs run at full speed
  on the host Mac - the only slowdown is in how fast you see the
  screen draw. You get used to this after a while and learn to do
  things such as let up on a menu option when your cursor is in the
  right place but before the highlight has caught up with you.

  The second limitation from which Timbuktu Pro suffers is that you
  cannot reach out and touch the host Mac, if you're controlling it
  over the Internet. This may not seem like a major liability until
  the Mac crashes or needs to be turned off. You can do a fair
  amount with software, but there's no guaranteed way to recover
  from a serious freeze. In some cases, you can avoid the problem by
  using a shareware control panel called AutoBoot from Karl Pottie.
  AutoBoot looks for system errors or freezes and attempts to
  restart the Macintosh if it catches a crash. I suspect it would be
  a big help in working with a remote or headless Mac (a Mac without
  a monitor).  AutoBoot is available at:

ftp://mrcnext.cso.uiuc.edu//pub/info-mac/cfg/auto-boot-13.hqx

  Speaking of headless Macs, I hear that there's a problem with
  Timbuktu Pro 1.0 with headless Macs and certain types of user
  accounts - the problem is fixed by version 1.0.5, which you can
  get from Farallon.

  Although Timbuktu Pro would seem to be a focused tool mainly for
  use in situations where both people know each other, creative
  thinking reveals interesting uses. For instance, everyone
  complains about not being able to try software before buying it,
  except in crippled demo versions. A Mac running Timbuktu Pro could
  act as a demonstration Mac for someone connecting over the
  Internet - it shouldn't be difficult to use security software to
  prevent people from copying the programs. Farallon provides demo
  versions of some of their programs on their public Timbuktu
  server, most notably Replica and Timbuktu Pro itself.


**Administrative Details** -- If you want more information about
  Timbuktu or other Farallon products, you can get plenty via the
  Internet. Farallon runs an anonymous FTP site at
  <ftp.farallon.com> and a World-Wide Web server accessible at:

http://www.farallon.com

  Both sites seem to offer much the same information, ranging from
  technical notes about all of Farallon's products to press releases
  to free trial versions of Timbuktu Pro for the Macintosh. It's
  easy to navigate the Web site, but if you're connecting via FTP
  and want to find the demo versions, look in:

ftp://ftp.farallon.com/pub/farallon.products/timbuktu.products/freeversions/

  The free trial version works for up to seven days and on three
  Macs. During that time it works just like the full version, except
  that it won't connect to regular versions of Timbuktu Pro. You
  must use Apple's DiskCopy utility to create the installer disk for
  the free trial version.

  Timbuktu Pro requires System 6.0.5 or later (it works best with
  System 7), a minimum of 4 MB of RAM, a network, and, if you're
  using the Internet, MacTCP 1.1.1 or later.

  Farallon sells Timbuktu Pro through various distribution channels.
  Mail order prices seem to run at approximately $140 for one user,
  up to $1,400 for 30 users.
