- Of course, the hot news for the week is Apple's announcement of
- Newton, which is both a technology and the first Personal Digital
- Assistant. We have received a ton of information from lots of
- helpful people, but we had neither the time nor the space to
- report on Newton this week. Next week, we promise. Also, next
- week, a special upgrade offer for QuicKeys owners on electronic
- services only!

- AppleShare Upgrades
- It seems that Apple really wants everyone to upgrade to AppleShare
- 3.0 and has extended the upgrade program to 31-Jul-92. Apple
- claims they mean it this time, so this may well be your last
- chance to upgrade at a discount. It appears that you'll need an
- upgrade coupon, which is available on AppleLink in the AppleLink
- -> Apple Sales & Mktg -> Apple Programs -> AppleShare Server 3.0
- Upgrade folder. I suspect your dealer will have coupons or be able
- to get one for you.
-
- If you bought AppleShare File Server 2.0 between 15-Oct-91 and
- 31-Dec-91, your original, dated, itemized sales invoice and
- original Server Installer disk will get you a free upgrade. If you
- purchased only the AppleShare File Server 2.0 before 15-Oct-91,
- your original Server Installer disk and $299 will get you an
- upgrade. For those who purchased both the AppleShare File Server
- 2.0 and the AppleShare Print Server 2.0 before 15-Oct-91, you can
- send in your original File Server Installer disk and your original
- Print Server Installer disk and $199, and Apple will give you an
- upgrade. If you're still confused, talk to your dealer. Each of
- the upgrades carries with it a $7 shipping and handling fee,
- making even the free upgrade not so free. Send all those upgrade
- coupons to:

- WWDC Cool Stuff
- ---------------
- Apple recently held its Worldwide Developers Conference (WWDC),
- which is where they show the latest and greatest to all the
- developers who work on Macintosh products. Needless to say, this
- is where the truly cool stuff comes out of the woodwork at Apple,
- and from what we've heard, this year was no exception.
-
-
- Pens & Milo
- Of course, the big news has to do with handwriting recognition,
- and it sounds like Apple is taking their time to do it right. As
- Larry Zulch, president of Dantz Development said, "Pioneers get
- the arrows, settlers get the land." Apple aims to be a settler,
- and GO will have work to avoid being too much of a pioneer. Apple
- has managed to provided gestures, handwriting recognition, and
- basic mouse functions without rewriting the entire operating
- system, a generally smart move and a testament to the modularity
- of System 7. Handwriting recognition and mouse functions won't
- even require application support, but the more impressive
- gesturing abilities will require applications to be modified. In
- addition, Apple's handwriting recognition will require more
- hardware in the form of a graphics tablet, but those that want it
- will afford one, and the demand may drive the price down on those
- tablets.
-
- Perhaps the most impressive demo that people saw was something
- called Milo. Milo is a math program that uses the new Pen Manager
- and the handwriting recognition code in what a truly useful
- applications of pen technology. Perhaps a blow-by-blow description
- of the demo from our estimable Pythaeus will illustrate Milo's
- amazing possibilities best.
-
- "After everyone had seen the pen stuff and was truly impressed, a
- very unassuming young man came out and began READING off of a
- prepared speech to the audience. He never looked up! He just went
- ahead with what was actually a very good speech. Once he had
- explained himself and Milo, he started the demo. He first wrote
-
- 2 + 3 =
-
- and the machine responded with
-
- 5
-
- He then wrote something like
-
- 345 x 435 =
-
- and the machine gave the correct answer! OK, sure that's neat, but
- not all that difficult once you have handwriting recognition.
-
- He then wrote a complex algebraic routine with divisors and powers
- and all that stuff. The machine understood how to reformat the
- characters as things were added. (The divisor shifted the text up,
- etc.) It looked very much like MathType. But, the machine also
- understood what things in the equation stood for and knew how to
- work with them. When he dragged a value to the other side of the
- equation, the program subtracted it! When he moved a number to the
- bottom of the divisor, it made the power negative! This went on
- for a few minutes with interspersed clapping and cheering. (He
- still never looked up.)
-
- He then wrote a trigonometry equation, and the Mac immediately
- graphed it. He then wrote a simple line equation, and it added
- that to the graph. He then showed us how you could study the
- intersection by zooming in on the points in question. At this
- point he thanked the crowd, quit his demo, and began to walk off
- the stage. The crowd erupted into cheering and clapping and the
- whole hall gave him a standing ovation. Remember, these are
- developers! His manager had to bring him back onto stage where he
- took a slight bow, but was obviously overwhelmed by the crowd. It
- was the most amazing and utterly useful thing that I have ever
- seen on the Mac. And realize, it was running on a Quadra, but
- there was no time lag. Updates were instantaneous. In a couple of
- years we won't know what to do without this. As an engineer I only
- know that I want and need this technology now, and in the Personal
- Digital Assistants."
-
-
- OCE
- Apple's Open Collaboration Environment (OCE) is high on my
- personal list of must-have technologies. It will probably show up
- within the next year, ahead of most of the rest of the
- technologies at the WWDC, which is fine by me. Voice recognition
- and pen recognition are all fine and nice, but what I really need
- is a single mailbox on my desktop that will hold all of my mail
- from theoretically any email service, including voice mail, faxes
- (faxen?), Internet mail, and QuickMail. I hope to see most of the
- commercial services tap into this as well, since it's an obvious
- advantage for users to have a single Apple-created interface to
- all electronic communications.
-
- OCE is more than just a pretty face on email though, and may have
- the most long-term impact on the Mac as far as how groups of
- people work together, since it allows documents to stay in
- electronic form as long as possible, sometimes perhaps through the
- entire life of the document. It will be very interesting to see
- how all of this will be implemented.
-
-
- Translation Manager
- Leonard Rosenthol of Aladdin Systems said that the technology that
- impressed him the most was the new Translation Manager, which
- essentially combines the application substitution capabilities
- present in Finder 7 with the file translation capabilities of
- XTND. The Translation Manager will support transparent
- translations for files, the clipboard, and editions, and perhaps
- the best part is that it won't require any modifications to
- existing applications. In my mind, this is incredibly important
- because as the number of file formats increase, it's getting
- harder and harder to just double-click on a document or copy
- something and paste it into another application. The Mac's file
- types and creators were an excellent first step after the idiocies
- of DOS, but the Translation Manager will still be very welcome.
-
-
- Other stuff
- People mentioned a few other things, such as AppleScript, which
- should provide a simple method of scripting the Mac via
- AppleEvents. Frontier provides that right now, but is perhaps
- somewhat more suited to the programmer than the end user. Also
- some lists of cool stuff at the WWDC included the new QuickTime
- and QuickDraw GX, which will provide most everything to the Mac
- that Display PostScript provides to the NeXT. The one capability
- that will not show up in QuickDraw GX, but which will have to wait
- for later, is 3D capabilities. It's too bad, because 3D can add a
- lot to an interface, although it does work best with color
- monitors and faster Macs, which may account for the wait.
-
- The new QuickTime will support asymmetrical codecs (compressors /
- decompressors), which means that compression takes a long time so
- decompression is very quick, even on a slower Mac like an LC.
- Salient's AutoDoubler works like this. QuickTime will also support
- the new PhotoCD format from Kodak, so you'll be able to get all
- your 35 mm pictures on a CD for $20 at your local drugstore, and
- then play the CD on your Mac with future CD-ROM players (the
- current ones can only handle a single PhotoCD session, whereas
- later drives will be able to read pictures that are added to the
- CD in later session too).

- Word Style Flaws
- ----------------
- A few weeks ago I received a call from Prudence Holliger of
- Seattle's Mac Downtown Business Users' Group. Prudence was not
- happy and it was definitely Word 5.0's fault. Prudence has been
- working on a 300 page manual, and this manual has been in
- existence for several years, back as far as the late Word 3.0
- days. Like any good Word user, Prudence used custom styles
- heavily, and other people have added their own styles on occasion,
- sometimes duplicating existing ones, sometimes not. The result is
- a seriously complex document, in part due to sheer size, and in
- part due to numerous styles, some of which may not even go with
- any text any more.
-
- So why was Prudence unhappy? Well, there's this bug, you see...
- (Don't you hate sentences like that?). This bug under certain
- conditions sets the font information in user-defined styles back
- to the font of the Normal style. You are left with all of your
- text and your text still has your styles attached, but those
- styles do not contain the proper font information. With a small
- document with only one or two styles, this isn't a serious
- problem, since all you have to do is edit your style and add the
- font information again. But when you are working on a 300 page
- manual with a ton of styles, you probably have better things to do
- than spend a day fixing up the document one last time.
-
- There appear to be several actions that may activate the bug. If
- you create a document in Word 5.0 with styles in it, and then copy
- that document to another Mac, you might lose the font information.
- Lest you feel too much relief since you seldom copy files to other
- Macs, the other condition that can sometimes destroy the styles is
- adding or removing fonts from your System file. It's not clear if
- using Suitcase, Master Juggler, or the useful but stripped-down
- Carpetbag 1.2 ($5 shareware, and I highly recommend it for those
- who don't need the power of the commercial applications), will
- also cause the bug to show its ugly face.
-
- Luckily, there is a workaround and a method that will probably
- prevent the bug from occurring, although you're unlikely to think
- of either on your own. To work around the problem once it has
- occurred, do NOT save the document when you see it with the
- incorrect font information. Return to the original machine and
- open the document (or simply work with the original if it is still
- available). It should have the correct fonts. Save in Interchange
- format, perhaps better known as RTF (Rich Text Format), and then
- transfer the file again. Everything will work fine because RTF is
- a straight text format that is terribly hard to read because it
- describes every layout or typographic change with a textual
- marker. However, as straight text, there's little that can go
- wrong with RTF documents, and in fact, saving in RTF and
- reinterpreting is a good way to clear up other strange problems
- that may occur with Word files.
-
- If you are want to prevent this from happening, Microsoft
- recommends that you make sure that your machines have the same
- fonts available, so it sounds like there is some quirk with that
- old bugaboo, font IDs and font names. I ran into this several
- years ago with some older programs when I had Suitcase II renumber
- my fonts so there weren't any ID conflicts. Suddenly a bunch of my
- documents appeared in the wrong font, because the program stored
- the font by ID, which had just changed, rather than name, which is
- unlikely to change.
-
- Microsoft Tech Support told Prudence that it was a known, though
- rare, bug, and the Microsoft PR people offered this statement.
- "Microsoft is committed to quality products. We are aware of this
- problem and have suggested methods for working around it. We
- understand the severity of this problem and are planning to fix it
- and make it available free of charge to customers experiencing the
- problem." From the horse's carefully-worded mouth...
-
- I'm pleased that Microsoft realizes that the severity of this bug
- outweighs its rarity and will be fixing it for free. Sure, you can
- argue that there is a workaround and a method of prevention, but
- if someone doesn't know about the workaround, or a less
- sophisticated user encounters the bug, that person will have to
- recreate work, probably assuming that the computer is just acting
- up again. This is not to mention that saving in RTF all the time
- is a pain - in this day and age we shouldn't have to muck with
- such arcane tricks. And if you want to argue that because the bug
- is rare, it's not a big deal, you can tell the same thing to the
- very few people who lost a lot of work to the recent viruses. The
- fact of being in a small minority doesn't make reconstructing work
- any more fun.
-
- To tell the truth, this bug concerns me more than most. I'm less
- concerned about bugs that can cause the Mac to crash. You can
- always protect yourself from crashes by saving more frequently.
- This bug can secretly modify your work, which I feel is more
- serious than a simple crash. Consider this situation. If you are a
- student who works on your Mac at home in Word 5.0 but prints on
- the public LaserWriters on campus, you will have to copy the file
- to a disk and take it to the printer. If you're anything like most
- students at Cornell University, where I watched this behavior for
- several years, you'll work on any given paper until the last
- possible minute, at which point you'll print it out and hand it
- in, just on time. Being bitten by this bug as you trudge to the
- computer center, disk in hand, could make for some serious
- frustration. On the other side of the coin, if you work in a
- public computer room at a college, tell your coworkers about the
- workaround. If nothing else you're guaranteed to impress someone
- if you miraculously save some poor student's work.
-
- Perhaps far more dangerous is the instance of the graphic design
- firm that swaps files around a network with System 7 FileSharing.
- Design firms are more likely than students to rely heavily on
- styles because page layout programs can import and use those
- styles. In addition, such businesses are more likely to be mucking
- about with loading and unloading fonts frequently, thus increasing
- the possibility of the bug surfacing. Obviously, this bug does not
- affect the original file if copying the file is the cause, but the
- font trigger would indeed affect the original, and while a student
- can hand in a completely unformatted paper, a design firm will
- lose its collective shirt on such a practice, and it will be nice
- to see Microsoft release the fix. In any event, I encourage
- everyone to pass this article on to anyone you know who uses
- styles in Word - you could save them gobs of unnecessary effort.
-
-
- Style Manager
- In the process of commiserating with Prudence about the massive
- amount of work she had to do because of this bug, we talked about
- the concept of a plug-in module for Word 5.0 that would help
- manage all those styles. I won't say it's easy, since I talked to
- a programmer for Alki Software about it and he thought it might be
- tough to get that information from Word. Alki created the
- MasterWord floating palettes for Word that have limited GREP
- functionality, among other neat things like a cool table-making
- tool, so they should know. We'll have a review when MasterWord
- ships later this summer.
-
- What I'm throwing out for any budding programmers to consider
- then, is a Style Manager for Word 5.0. It should to list all the
- styles in any given document (the frontmost one), show a detailed
- list of what the styles contain, and show a character count of how
- much text is in that style. It should be able to link to Word's
- Find command so that you can browse the text that is in any given
- style, and once you've determined which styles are useful, you
- should be able to have one style take over from another (in the
- case of the fictional "Body Text" and "normal stuff" which are
- actually identical styles), and be able to delete unused styles.
- I'm sure there's other useful stuff it could do as well, and I'll
- bet people would pay $30 to $50 for such a utility.
-
- In many ways, Word is the best word processor for long, complex
- documents that are destined for a page layout program, but it also
- seems that Microsoft often aims it at the one page business memo
- crowd by not adding features that could turn it into a seriously
- useful document processing program. Such a Style Manager would
- help a great deal, and I'm sure there are plenty of other useful
- suggestions in this arena, such as cross-references and the
- ability to start page numbers at any arbitrary number. Apparently
- people also want the ability to combine landscape and portrait
- printing within the same document too. Better get your votes in
- for Word 6.0 soon, although it may already be too late.

- QuickRing Speed
- ---------------
- Let's face it, we computer users are greedy. We always want more
- power, more speed, and more time. Luckily the more advanced people
- at Apple (not the geniuses who gave us the crippled Classic) think
- along the same lines and have come up with a new technology called
- QuickRing, which promises to significantly enhance the Mac's
- utility in some data transfer-intensive tasks.
-
- Each successive generation of Macs runs faster than the last, but
- the Macintosh still some notable bottlenecks, including SCSI, the
- memory subsystem, and the processor itself. One bottleneck that
- you may not often notice is the NuBus. Currently, NuBus is limited
- to transfer rates of about 20 MB per second on the Quadras and 10
- MB per second on the older machines. A friend calculated that only
- a 33 MHz 68040 will begin to outpace the this bottleneck.
-
- Apple apparently feels that 20 MB per second is not up to snuff,
- since snuff-induced sneezes travel pretty quickly, some 200 miles
- per hour according to a book I read many years ago. Enter
- QuickRing. QuickRing is a high-speed architecture for data
- transfer between NuBus cards in the Mac so that they can move data
- faster than ten times the maximum speed of NuBus, or 200 MB per
- second. That's something to sneeze at. Keep in mind that although
- the cards will be NuBus cards, there will have to be a faster
- connection to the CPU than what the NuBus offers. I anticipate
- that Apple will either use some sort of direct connection to the
- CPU (unlikely) or the Processor Direct Slot (why do you think they
- call it that!).
-
-
- What's it good for?
- What would you want to do that would require that sort of speed?
- If you only use one NuBus card, you probably don't need the speed.
- But, if you use several cards simultaneously, the speed could come
- in handy. Most of us don't use several NuBus cards at the same
- time, but that day may come sooner than we think. Here's some
- examples of what QuickRing will be good for.
-
- Apple's pushing a lot of high-technology announcements out the
- door these days, which is a heck of a lot easier than actually
- pushing the high-tech out the door. Whenever you talk about voice
- recognition or accurate handwriting recognition, you have to think
- about extra hardware. It's possible to do it in software, but the
- more processing power you can throw at voice recognition, the
- better it can do and the more it can do with what it hears. Voice
- recognition is perfect job for a fast card with a digital signal
- processor (DSP) chip, though Apple may manage to get it working
- completely in software on today's high-end Macs.
-
- QuickTime is nice idea and seriously snazzy, but let's face it,
- watching a five second clip of "Star Wars" on a postage stamp
- isn't exactly my idea of entertainment. To produce serious
- QuickTime movies you need hardware, and the more you have, the
- better. Today's hardware (like a VideoSpigot) lets you do real-
- time video in a 160 x 120 pixel window - increasing the window to
- size of an index card will limit the frames per second. However,
- if you can throw some faster hardware at the problem with one card
- to bring in video, another to compress it, and a third to display
- accelerated graphics, you could probably capture full-screen
- real-time video, assuming you had that sort of hard disk space.
- Alternately, a 13" color TV and cheap VCR will do the same thing.
- :-)
-
- Another proposed use is in high-speed networking, although the
- current NuBus is more than sufficient for even a theoretically-
- fast Ethernet network, which runs at 10 megabits per second
- (Mbps), and even a super-fast 100 Mbps network could in theory
- work with NuBus, although there would certainly be speed-eating
- conflicts if anything else was using the NuBus at the same time.
- The main things I can imagine that would require such speeds would
- have to do with complex graphics or video. Videoconferencing might
- come into its own with QuickRing, especially since there's very
- little processing that would have to go on, so the processor and
- memory systems wouldn't be limiting factors.
-
- Of course, once you've got a tremendously fast network, you will
- probably want to do some distributed processing of all those 3-D
- rendered QuickTime movies you'll be making. Sending some of the
- processing work off to other Macs on your network will work fine,
- but there's no need for new technology for that. You could also
- put multiple processors in one Mac and have them communicate very
- quickly to off-load processing from your primary CPU. Radius is
- already working on this sort of thing with its Rocket accelerators
- and RocketShare, and perhaps there are some multiple processing
- applications that could benefit from this, although the Mac would
- need much faster memory to really take advantage of it.
-
-
- Why it's cool.
- I've perhaps sounded slightly dubious about some of these uses,
- but Paul Sweazey of Apple's Advanced Technology Group pointed out
- why QuickRing truly is a big step. Although the NuBus doesn't seem
- like a major bottleneck, you have to keep in mind that it has to
- carry numerous different tasks. So in a common setup, you might
- have an EtherTalk card, an accelerated video card, and maybe a
- Radius Rocket, all in the same Mac. None of those individual tasks
- will present any threat to the bandwidth of the NuBus, but
- together, they might come close. Add in a voice recognition board
- and something to capture real-time video, and you've seriously
- overloaded NuBus, which would have been more than enough for one
- of those tasks.
-
- Even more important is the fact that NuBus is fairly inefficient,
- so the three tasks will bump into each other all the time. No one
- anticipates needing 200 MB per second of throughput with one task
- on QuickRing, at least not right away, but in the meantime, it
- will provide faster real-world speed to multiple slower tasks.
- Think of NuBus as a two lane highway that bogs down when there are
- 50 cars all trying to enter and exit at the same time. QuickRing,
- in contrast, would be the equivalent of a 20 lane highway for
- those same 50 cars. Plenty of room.
-
- Interestingly, Apple decided to get help with QuickRing, and it
- was developed jointly by Apple's Advanced Technology Group,
- National Semiconductor, Molex, and Beta Phase. National
- Semiconductor designed the controller chip, and Molex and Beta
- Phase cooperated on designing and manufacturing the interconnect
- system to go between the cards. Apparently, the hard part was to
- create the chip and the interconnect system using conventional
- methods so that the finished products could be produced in high
- volume and at a reasonably low cost. The problem was that these
- controllers and interconnect systems have been done in the past,
- but only to work with Cray supercomputers and the like, and you
- just don't worry too much about producing anything for a Cray in
- volume cheaply. There just aren't enough Crays around and they're
- so expensive that no one worries about the price of a controller
- chip here or an interconnect system there.
-
- It will be a while before QuickRing products appear, but I believe
- they will be compatible with current high-end machines, so that
- won't be a limiting factor. In fact, it seems that without faster
- processors and faster memory, we won't be able to do much at all
- with QuickRing. However, processors, memory systems, and disk
- storage systems have all significantly increased in either speed
- or capacity in the last few years, and the main area left dormant
- has been the bus systems. QuickRing may provide more than the rest
- of the Mac can handle, but so what? Aldus could never have created
- PageMaker 4.2 if all we had was double 800K floppies. QuickRing
- pushes the performance envelope, and the rest of the systems will
- play catch-up with what it makes possible for few years, just as
- software developers were suddenly able to create huge applications
- like PageMaker once most everyone had a hard disk.
-
- Look for components to start being available to developers in
- early 1993, which means products might show up sometime in
- 1993/94, or a bit before the future fantasy time when Taligent is
- supposed to deliver Pink. Developers interested in QuickRing can
