- TidBITS#140/31-Aug-92
- =====================
-
- First, the mundane but useful, with an important tip for Excel
- users, a clarification about Conflict Catcher, a new 32-user
- license for A/UX, and a report of the imminent demise of the
- Portable battery supply. Following that comes the cool stuff, a
- neat in-ear speaker and microphone (i.e. telephone) that works
- via bone conduction, some MacDraw Pro 1.5 speed benchmarks, and
- Microsoft and Tandy's answer to Commodore's CDTV.

- Excel Workbook Backup Tip
- -------------------------
- In TidBITS#133 Andy Williams passed on a warning about a
- potentially dangerous bug in Excel 4.0 that could cause you to
- lose data bound into a workbook. The problem arises if your
- computer crashes while saving, because Excel will have overwritten
- the old, complete version with the newer, incomplete version, and
- you then can start on the hair-pulling. At the end of Andy's note,
- I mentioned that a clever macro programmer could probably script
- an automatic backup to ensure that you always had two copies of
- the workbook when you were working on it. Luckily for the Excel
- community, our local Seattle Excel guru Howard Hansen has come up
- with a workaround that doesn't even require a macro and will
- create a backup of the workbook every time you save. To do this,
- follow these steps:
-
- 1. Activate the workbook's contents page.
- 2. Choose Save As... from the File menu.
- 3. Click the Options button. Excel will bring up its Options
- dialog box.
- 4. Check the Create Backup File checkbox, then click the OK button
- to close the Options dialog box.
- 5. Click the Save button to save the file to disk (and make a
- backup).
-
- Excel will now take the old workbook file and rename it "Backup
- of" and the name. If anything evil happens during a save, you will
- always have the backup.

- Conflict Catcher Article Conflicts
- ----------------------------------
- by Jeff Robin of Casady & Greene -- JLRG9912@UXA.CSO.UIUC.EDU
-
- I want to correct some misinformation in TidBITS#139 about
- Conflict Catcher. The article claims that Conflict Catcher
- automates the process of loading startup documents one-by-one to
- identify conflicts. Conflict Catcher does not load INITs one-by-
- one, but instead loads half of the startup extensions at a time to
- minimize the number of restarts it takes to locate an INIT
- conflict. Here's how Conflict Catcher begins to tackle a problem.
- After you start Conflict Catcher, it loads the extensions that it
- wants while restarting the computer. When the Finder comes up, you
- check to see if the problem exists (and that includes opening an
- application if that's where the problem shows up), and restart the
- computer. Conflict Catcher will then ask you if the problem exists
- or has gone away and enables or disables extensions as needed. It
- usually takes about four or five restarts to pin down a conflict,
- although that of course varies with the number of INITs you use.
-
- Conflict Catcher is always the first INIT to load, so if the
- conflict is between two INITs and causes a crash during startup,
- you can inform Conflict Catcher that the problem exists when you
- restart the machine. If the problem is more subtle (i.e. the
- Finder has a corrupt display), then you tell Conflict Catcher when
- you restart.
-
- Also, Conflict Catcher is able to isolate conflicts between
- multiple INITs. The article also mentioned incorrectly that
- Conflict Catcher somehow traces code after startup. Actually,
- Conflict Catcher only patches a few traps to perform the startup
- file reordering and to do the ICON wrapping. Both of these
- features can be disabled so that Conflict Catcher is guaranteed
- not cause any problems.
-
- [Thanks for the explanation, Jeff. It sounds as though Conflict
- Catcher will help the user identify and solve conflicts, which is
- even better than it doing it automatically because then the user
- will learn from the process as well. -Adam]

- A/UX... More Is Better?
- -----------------------
- by Mark H. Anbinder, Contributing Editor
-
- Apple recently announced to dealers a license upgrade option for
- owners of the 16-user license of A/UX 3.0, Apple's Unix operating
- system, bringing the maximum number of users to 32. Until now,
- each A/UX workstation was limited to 16 users, but Apple is
- providing this expanded user license option for customers with
- "growing enterprise-wide systems."
-
- For $2,500, users will be able to order the license kit, which
- enables a single A/UX installation to support up to 32 users. We
- suspect that most designers of "enterprise-wide systems" would
- have selected either individual Macintosh workstations, or some
- other time-sharing system, but for those who felt a 16-user A/UX
- system would suffice and are now discovering they just can't get
- enough A/UX, this license upgrade should fit the bill.
-
- The license kit (item number M8099LL/A) is available directly from
- Apple Software Licensing, but the required form is on AppleLink
- under the path Apple Products -> A/UX -> Ordering & Licensing ->
- Licensing -> A/UX 32 User License & Instructions. Users without
- direct access to AppleLink will need to acquire the form from
- their dealers, who may be miffed that Apple is handling all these
- sales directly.
-
-
- Portable Battery Bye-Bye
- ------------------------
- by Mark H. Anbinder, Contributing Editor
-
- Owners of the discontinued Macintosh Portable will feel even more
- left out this fall, when Apple plans to remove the Macintosh
- Portable Battery from all of its price lists. The separate battery
- was intended for users who wanted the convenience of having an
- extra battery on hand for those long computing sessions away from
- any AC outlets. Of course, most users have found the single
- battery that came with their Portables to be sufficient for
- working several-hour stretches so long as they recharged the
- battery between work sessions.
-
- If you have a Portable, and you've thought about investing in a
- spare battery, now is certainly the time; the 19-Oct-92 price
- lists will no longer include the item, dealers may be unable to
- get the batteries, and we have not yet run across a third party
- supplier of the batteries. We suspect that limited quantities will
- be made available to dealer service departments, in case a
- customer's battery needs to be replaced someday, but you may want
- to get yourself a spare just in case.

-
- Norris Ear PHONE
- ----------------
- One of the most interesting technologies I saw at Macworld had
- little to do with the Mac. So why did this company come to
- Macworld? The technology enhances various communications
- applications, and lots of Macintosh companies are working on
- improving communications using the Mac.
-
- The product in question comes from Norris Communications, and they
- call it, appropriately enough, the Norris Ear PHONE[tm]. The Ear
- PHONE is this little item that you put in your ear, much as
- someone might wear a hearing aid or old radio earplug speakers.
- Unlike a hearing aid or radio speaker, the Norris Ear PHONE acts
- as both a speaker and a microphone. At the moment it uses a
- unidirectional microphone that works wonderfully, although I found
- it disconcerting to talk to someone on the phone without holding
- anything. (Norris kindly gave Mark Anbinder and me a private
- demonstration so we could try it.)
-
- As neat as the unidirectional model was, Norris has an even more
- theoretically impressive version in the works. They only brought
- two prototypes to the show, and other people had them when we were
- checking out the unidirectional model, but the prototypes work on
- the principle of bone conduction. For those of you who aren't
- familiar with the principle, when you talk, you set up vibrations
- not only in the air surrounding you (causing the sound) but also
- in the tiny bones in your ear. Bone conduction microphones do not
- pick up any background noise, because that noise doesn't cause the
- bones in your ear to vibrate. You can also speak in a low voice,
- because all you have to vibrate are those bones, not the air
- around you.
-
- I don't have a sense of how sensitive the bone conduction
- microphone will be yet, but I suspect that you won't have to talk
- as loudly. As Mitch Ratcliffe of MacWEEK commented, however, it
- will be hilarious to see gray-suited executives walking aimlessly
- around the streets, apparently mumbling to themselves like
- unstable street people.
-
- The first model of the bone conduction microphone will hook to the
- phone via a cord, but Norris has a wireless 900 Hz spread spectrum
- model in the works as well, so eventually your phone won't hold
- you hostage at all. You may not have to slap your chest as do the
- actors in Star Trek: The Next Generation because Norris hopes to
- have the Ear PHONE be voice-activated, but one way or another,
- your personal connectedness will increase radically. Of course,
- you will then have to decide all the more whether or not you wish
- to accept incoming calls, but technology seldom comes without some
- philosophical involvement. I know people who still refuse to have
- a telephone, and when forced to use one are uncharacteristically
- rude.
-
- As far as applications of the Ear PHONE go, Norris showed some
- relatively simple ones and a few more impressive ones. Many of us
- keep our phone and address information on the Mac now, and some
- people even use their modems (or a little hardware device from
- Sophisticated Circuits) to dial the phone. Eventually Norris wants
- the Ear PHONE to work as both a telephone speaker and microphone
- and also as a voice command microphone for the Mac. Once we have
- Casper voice-recognition technology (about the same time we all
- have Cyclone Macs and a chicken in every pot), I could have the
- Mac dial the phone with a voice command, and without doing
- anything else, suddenly be talking to someone, all without
- fiddling with handsets and keypads and all that. I gather that
- Apple will also better integrate telephony into the Mac via the
- Comm Toolbox and OCE, so that applications will have an easier
- time working with telephone applications.
-
- The more interesting uses of the Norris Ear PHONE include using it
- as the microphone and speaker in a system from Applied Engineering
- that will replace the floppy drive in a PowerBook with a
- communications bay (this is cool stuff, more on CommPort in the
- future) or in a ShareVision system (incidentally, I received some
- incorrect information that I used in the ShareVision article in
- TidBITS#138. Dean Tucker of ShareVision alerted me to the problem
- and offered to clarify and expand on some of what I said, so look
- for another article with better information in the next week or
- so).
-
- One added benefit of the Norris Ear PHONE: those of us with hand
- and wrist injuries from typing too much will not have to hold a
- handset. If you haven't experienced any pain in your hands you
- won't know what I'm talking about, but I find that a long
- telephone conversation can cause me a lot of discomfort. I could,
- of course, get a headset, but they are expensive and not always
- that comfortable either from what Tonya and other tech support
- people have said. A speakerphone would work too, but you can't
- have a private conversation on a speakerphone.
-
- You can't buy the Ear PHONE just yet since Norris hasn't started
- full production runs, but they do have a Partner program that will
- provide you with an Ear PHONE, technical information from the
- company, and both phone and CompuServe tech support. It costs $99,
- and if you're interested, give Norris a call.
-
- Aside from the two minor drawbacks of executive zombies and
- figuring out to deal with always being available, the only
- remaining question has to do with RF emissions. I doubt the
- speaker would cause a problem since hearing aid companies would
- have tested that, but few other companies have put a radio
- transmitter in the ear itself, and even the slight distance of a
- headset radio could reduce the RF emissions enough to eliminate
- potential health problems whereas an in-ear transmitter might be
- too close. And of course, it may seriously impact the career
- opportunities of telephone sanitizers. For that matter, you may
- not want to share Ear PHONEs with other people all that often...
- (Norris actually will provide a number of pads to address the
- cleanliness issue and so people with different size ears can find
- the most comfortable fit.)
-
- These real and humorous concerns aside, I have high hopes for the
- Ear PHONE. Norris has to make sure the voice quality of the bone
- conduction version equals the quality of the unidirectional
- version, and they also have to ensure that the price at least
- competes with traditional headsets. If Norris can meet those
- design goals, everyone will want an Ear PHONE. If not, it will go
- the way of other niche market electronic devices, including a few
- that have used bone conduction unsuccessfully even when you
- inserted the device deep in your ear. I think I'd rather have a
- Babel fish, but barring that, I'll take an Ear PHONE.

- MacDraw Pro Speed Comparisons
- -----------------------------
- by Nigel Stanger -- STANGER@otago.ac.nz
-
- I just got my upgrade to MacDraw Pro 1.5 and since lots of people
- on the nets wondered how fast it was compared to previous
- versions, I decided to try a few rough and ready benchmarks on the
- two versions. All tests were run on an LC (original, not II). The
- tests I tried were:
-
- * "Cold start" - launch to a new blank document
-
- * Open four of the sample documents which came with it:
-
- "GeoMosaic" - a fairly simple straight-line geometric
- pattern with gradient fills.
-
- "Rossini" - similar to GeoMosaic but with more curves
- and slightly more complex gradients.
-
- "Dance of Spheres" - I think this was originally an Escher
- print. It certainly looks very familiar. Lots of spheres
- hovering over nested, rotated squares and lots of gradients.
-
- "4 Cylinder Engine" - a rather spectacular cutaway of a four
- cylinder engine. Definitely the most complex.
-
- * Scroll "4 Cylinder Engine" one "step" of the scroll bar.
-
- * Open a new document (command-N).
-
- * Type in some text. The idea here was not so much to get a time,
- but to see how well it kept up with my typing.
-
- It appears that 1.5 gains most of its speed increases from its new
- display options - you can opt for either "best" display of
- gradient fills, or "fast" display (which appears to mean dithering
- as far as I can tell). You can also greek imported images, and
- text below a certain point size. This is basically the same as the
- "picture placeholders" command in Word, where Word substitutes a
- solid box for the actual graphic in order to increase scrolling
- speed.
-
- The default setting for text greeking is six point - anything
- smaller is drawn as a placeholder, which saves a lot on TrueType
- rendering. If you've ever used Print Preview in Word 4.0 with
- TrueType fonts, you'll know how bad it can get.
-
- The test results are below. Times are in seconds, rounded to the
- nearest half second. The degree of error is plus or minus about
- one second depending on my reaction time :-).
-
- 1.0v1 1.5 (fast 1.5 (normal
- Test gradients) gradients)
-
- Cold start 19.5 17.5 --
-
- Open GeoMosaic 12.5 14.0 14.5
-
- Open Rossini 29.5 16.0 30.0
-
- Open Dance of Spheres 29.5 17.5 30.0
-
- Open 4-Cyl. Engine 69.0 62.0 72.0
-
- Scroll 4-Cyl. Engine 6.5 7.5 8.5
-
- New document 6.5 7.5 --
-
- The most spectacular results seem to be in the moderately complex
- (i.e. more or less average) documents. Simple documents and
- highly-complex documents don't seem to be much different than from
- 1.0. The overall feel does seem slightly faster though. Text entry
- has improved - I managed to leave 1.0 behind quite easily, whereas
- 1.5 kept up fairly well.
-
- Other new features: Publish & Subscribe, QuickTime support, Apple
- Event support (including a HyperCard stack for driving a slide
- show via Apple Events), Balloon Help, and improved text alignment
- (which I haven't had a chance to look at yet). Personally, I think
- Publish & Subscribe is justification enough for upgrading - I've
- been drooling ever since I heard 1.5 had it.
-
- On the downside, MacDraw Pro 1.5 is still significantly slower
- than MacDraw II, but I expected that. The program also checks in
- about 200K larger than 1.0 (which was already 1 MB), but the RAM
- consumption has not changed. The package comes on only four 800K
- floppies as opposed to six for 1.0 because half the stuff is
- compressed, which I consider a good idea. I have enough floppies
- sitting around already. The Installer was up to its usual mediocre
- standards - I installed MacDraw Pro on a partition without a
- System Folder on it, and the Installer went and created a System
- Folder to put all the extra bits and pieces into, which meant
- moving some stuff around by hand.
-
- Oh yes, one nit which I almost forgot - MacDraw Pro doesn't seem
- to understand foreign script systems! I have the Russian script
- system installed (long story), and if you run Key Caps, all the
- Russian fonts appear in the Font menu in Cyrillic - very nice.
- However, both Word 4.0 (surprise) and MacDraw Pro don't do this -
- the fonts appear as gibberish (characters in the >127 ASCII
- range). A bit disappointing, given the quality of the interface
- otherwise.
-
-
- Windows Does CDs
- ----------------
- Apple certainly has the head start on the potentially lucrative
- (at the price of this hardware and software, _someone_ had better
- make some money at it) multimedia market, but as Mark H. Anbinder
- pointed out last week, IBM wants in on the action too. Although it
- turns out that IBM's snazzy full-screen full motion video
- demonstration had some special hardware behind it (more next week
- when we find out all the details), other companies want some of
- the pie too, and where there's a pie, could Microsoft be far away?
- No.
-
- Remember the $800 CDTV, Commodore's primarily unnoticed attempt to
- enter the consumer multimedia market? If not, don't worry, despite
- the fact that CDTV was actually an Amiga in sheep's clothing (see
- TidBITS#62/20-May-91 for the details at the time), CDTV hasn't
- exactly taken the world by storm, due in part, I'm sure, to
- Commodore's inability to sign up enough third party content
- providers. Microsoft and Tandy hope to do just that, although I
- doubt they'll equal Hurricane Andrew in importance.
-
- The hardware comes from Tandy, and they call it the Video
- Information System, or VIS, and hope to sell it for about $700.
- The software, as usual, comes from Microsoft in the form of
- Modular Windows, which Microsoft optimized for use with a
- television as a display device. Microsoft obviously wants certain
- developers already working on Windows products to scale them down
- for use with Tandy's VIS, and since Modular Windows for VIS is
- based on Windows 3.1, developers shouldn't have too much trouble,
- assuming they have already mastered programming Windows, something
- which various programmers of my acquaintance have likened to
- eating okra (that ought to get both okra aficionados and Windows
- programmers, all in one sentence :-)).
-
- Of course, the software interface concerns us the most. Modular
- Windows, being Windows at heart, relies on DOS, and yes, Tandy's
- VIS includes both MS-DOS and Modular Windows in ROM (warning,
- acronym level rising!). So you have no choice about the underlying
- operating system, but the interface? Microsoft claims that they
- have tested the interface with hundreds of users (I wonder who?)
- to ensure that users can see and use the software easily from ten
- feet away. According to Microsoft, multimedia titles will feature
- large, three-dimensional buttons and colorful icons and support a
- simple point-and-shoot operation with a remote control. In theory,
- users won't have to know that VIS uses DOS and Windows at all, but
- frankly, given Microsoft's interface "successes" with computer
- users who are theoretically slightly brighter than the average
- bear, I'd advise average bears to stay in hibernation.
-
- At first, VIS players will look and act much like CD players that
- sit on top of and attach to television sets. Later on the VIS
- player will support alternate methods of delivering information,
- most likely through cable television channels. All of this sounds
- like Commodore's CDTV, although Commodore was a mere rhesus monkey
- to Microsoft and Tandy's 2000 pound gorilla. Supposedly Tandy and
- Microsoft have over 50 developers committed to over 100 VIS
- titles, including a number of children's reading development and
- classic literature titles. Joy and rapture! Can you imagine
- reading the complete works of Shakespeare on TV? My copy of
- Shakespeare's complete works numbers almost 1000 pages of small
- print, not something I'd care to experience in large letters and
- short lines, even if I can switch to clips of various productions
- of Hamlet while perusing the text. Of course, I'm being negative
- here, not having seen what they propose in terms of "classic
- literature titles," but unless they can equal at least what
- Voyager has done with the neat Expanded Books, I'll stick to my
- awkward thousand page book or the free ASCII texts from Project
- Gutenberg.
-
- Even though Tandy will sell the VIS system in consumer electronics
- and department stores, it seems that they plan to market the
- titles as software. I can't imagine that the sort of people who
- buy software will evince all that much interest in VIS - why
- bother when you have a computer that can do as much and more? If
- VIS is to succeed then, it will have to break consumer molds and
- not just try to slip another sheepskin-covered computer into
- consumer electronics stores.
-
- As it stands, the hardware specs sound pretty good, including
- VGA/MCGA compatible video modes on a television; new video modes
- that support up to 16 million colors; hardware-assisted animation
- processing; three types of high-quality audio (CD-Audio,
- synthesized MIDI, and wave-form) played simultaneously for cool
- effects; and DOS, Windows and multimedia PC (MPC) software and
- content capability (what the heck would anyone do with that?). In
- the end, you've got hardware that might approach an Amiga, which
- most people consider the best multimedia machine commonly
- available. But does the Microsoft and Tandy gorilla have enough
- weight to muscle a $700 VIS into the hearts and homes of
- consumers? Not this one.
