This has got to be the most outrageously coolest thing I've done with
construction mode. It makes finding a person's name extremely fast!

(This is not a risky trick and it won't crash your communicator as long as
you follow my directions.)

WHAT YOU NEED:
You need two packages in order to do this:
1. Tinker Tool
2. SysImages program
OR
1. Coupon Grabber
2. SysImages

HOW TO DO IT:

- go to the desk scene
- tap the MAGIC LAMP
- tap tool holder
- option tap title bar of tool holder
- select COPY
- tap and drag the FIND button in the Magic Lamp and place it on the desk
- Now go to hallway and enter SysImages room
- Find the object that looks like a question mark with a circle around it
(Like the one on the top left corner of every scene).
- option touch when you find it and drag it in your totebag.
- go back to desk and place questionmark object next to FIND button on desk.
- open tool holder and option tap title bar.
- tap on either the tinker tool or Coupon Grabber
( Whichever you have...I will assume you are using tinker tool).
- Now touch the question mark object on the desk
- a screen should pop up
- touch and drag question mark image coupon and place it on desk.
- Now throw away the questionmark object so your left with the Question mark
coupon and the FIND button on your desk.
- drag the qustion mark coupon on top of FIND button and let go.
- Now FIND button turns into question mark.
- Select MOVE from the tool holder and move the question mark exactly on top
of the questionmark on the top left corner of the screen.
- Now enter the NAMES Rolodex and tap the questionmark on the top left corner
of the screen.
- the find button should pop up...make sure that SEARCH EVERYWHERE is not
checked and FASTER is checked

IMPORTANT PART!!! DON'T STOP READING YET!
-since magic cap makes MACROS for you automatically, all you have to do is
enter a persons initial on the keyboard (ei: RO = Rishi Oswal) and tap EXPAND
( Graffiti users would draw a cursive lowercase L for expand ) and then
RETURN or GO and TADAAAA...the person's name will be found for you
instantly!!

You can use this feature in any place such as datebook or file cabinet also.
The  real questionmark feature still works fine as long as you don't tap
directly on the questionmark.

Hmmmm...Maybe I'll demonstrate this and other cool tricks at BAMCUG!

I tried, unsuccesfully, to run Presto!Mail/Presto!Links on my PIC 1000.
After numerous calls to General Magic's support line and numerous
contacts with General Magic it still doesn't work. My experience is that
this package does not run well on the 1000 (even though Gen Magic told it
would when I purchased it.).

I have Presto!Mail and Presto!links running on a pic-1000 with the 1.0f
patch installed. It even works. I have both sent mail and retrieved web

Nice of you to 'kindly' inform her what the program was doing. Too bad the
program wasn't taking on that responsibility itself. I consider that to be
irresponsible behavior. The *computer* was correcting *her*? Without any
notification on the program's part I assume, since she came to you
'yelling' that it was making the changes. I only hope you weren't this
sloppy during the updates - OK, save my changes to this critical db,
saving, fine, OK....hey, why is the machine power recycling????? What
happened to my open WordPerfect doc?

Not to mention the fact that if you were recycling every time you did an
update, it must be hell on the user's productivity. The users I've worked
with would almost certainly end up making huge numbers of changes without
updating - inducing a *far* more dangerous situation - if they knew that
every time they corrected a spelling error in a field the machine was going
to reboot. Or perhaps I misunderstand.

I find the practices you describe above irresponsible and unprofessional in

condescending and arrogant.

Dear MagicCap,
Well, it looks like General Magic is going to have some fierce competition in
the next 3 - 6 months. Magic Cap vs JavaOS( OS designed specifically to run
Java applets with little OS overhead) vs Newton vs Pegasus vs GEOS vs Psion(
they are coming out with new OS that will run on ARM chips). Even in JAPAN,
Apple just released the Japanese version of Newton 2.0. General Magic is
supposedly almost done with their version of Japanese Magic Cap ( version 2.0
or 1.5?) and hopefully they will ship it soon before Newton catches on over
there.

HERE's TO General Magic!!
May your future be filled with magic.

P/S: I am thinking about creating a biweekly news summery for Magic Cap based
PDA's on a web site designed exclusively for PDA browsers. If I decide to do
it, it will be similar to the already successful and proven NewtNews format
by Steve Holden ( which by the way is a great weekly newsletter for newton
users). Please let me know if you would be interested in such a publication (
It would be free). I am still working on getting an ISP that offers webspace.

Dear MagicCap,
Tinker tool goes one step beyond construction mode in allowing you to
customize your Magic Cap based device. It was so powerful that General Magic
left it out of shipping products simply because it was very easy to do
destructive things to your communicator with it. I personally have found it
invaluable and use it practically eeveryday. To install it:
Tap the toolholder
option tap title bar
select MOVE
option touch tool holder
drag tinker tool and place it below stretch tool.

USE AT YOUR OWN RISK

you might want to try Vartec Telecom.  They charge 10 cents a minute regardless

can use them by diallinng 10811 before your normal digits (yes you still dial
1 after 10811).  There is a $5 per month access fee, but they don't seem to
assess it consistently.  I used to spend $200-$300 each month with MCI too.
Vartec customer service is at (800) 583-6767

No, I don't work for them.  I just really like the idea of being able to predict
what my phone calls will cost, and I hated how Sprint charges more during the
day for their "dime line".

Sometimes calls do not go through "sorry all circuits are busy" but I would
rather try the cheap way first, then use ATT or MCI or Sprint.

Sounds great.  You know AOL offers web space at no additional charge.
You get two meg per screen name and you can have up to five screen
names on an account giving you ten meg to play with.  You can use it as
private or public ftp space too.

I use an Apex MobilePlus 28.8 with Wireless Link and a landline with good

  Gordon,

  First suggestion for you to try is to pack up the AOL package and
unpack it again.  You can do this by going into the Storeroom to the far
right side of the room and tapping the AOL package.  You'll have access
to a 'pack up' button in the upper-right portion of the screen.  After
it packs it up, power cycle your device and go to the package and unpack
it.  Now try to enter the building.

  If this doesn't work, although it may result in a need to enter your
user data again, you may wish to try deleting changes for the AOL
package.  To do this, go into the Storeroom and tap the AOL package to
get its package screen up.  Then tap the Magic Lamp.  You'll have access
to a 'Delete Changes' button here.  This will wipe out all changes made
to the AOL package, including sign-up information, rules for news/stock
collection, etc. but as a last resort should set the building back to
normal if all else fails.

Luke Derossi

Apologies to the list and Kevin, but I can't resist such obvious flame-bait ... ;-)

So, let me get this straight: you design a UI that allows the user to enter
conflicting information; you check for conflicts, and you then change one of
the pieces of information automatically without alerting the user that you
did so ?

In the Magic Cap arena I think this could translate to detecting that an
incoming mail message is too big and deleting it, for your PDA's safety ...

>Excuse me if I expect the same level of proffesionalism from others

Professionalism has one "f" and two "s"'s.


Disregarding the above, I happen to partially agree with elements of Kevin's
message. He is correct in asserting that it shouldn't be possible for a user
to crash a machine such as a Magic Link (even if crash is slightly the wrong
word - "inelegantly restart" is perhaps more accurate ;-).

In particular, with POP e-mail it is possible to determine the size of the
message before pulling it into memory (though not from within FarCast) and
allocate sufficient space (and check if the allocation succeeded). I think
Presto!Mail does exactly this as I can set a rule to ignore messages larger
than a certain limit. I believe the problem comes when you have to transfer
the contents of memory from one package to another, and it's not possible to
simply hand over ownership of the memory - it has to be copied again. Someone
correct me here if I am talking out of my rear end here ... Anyway, this
could be seen as a deficiency of Magic Cap, but I believe it also has
advantages - there is probably more detailed discussion of the Magic Cap
memory model and memory management on their website in the developer corner.

Well, life at the bleeding edge is tough. Create something an idiot can use
and only idiots will use it ...

No honest injun, its a great book.  Just because microsoft doesn't
follow these rules too often doesn't mean they are not great
guidelines.  It was written by a manager at microsoft.  The book is
written at a fairly technical level, so this is not for ameture
programmers.  But ifyou write programs for a living (especially if you
write in C) its a no brainer.  The topics are equally appropriate to
single person shops as large software houses.  Since the ideas are
platform independant, it is useful for programmers in all operating
systems.

Microsoft press has quite a few great books that are general
programming books that are fantastic.  Another book in this category is
called 'Code Complete'.  Again, it is not windows based so it is useful
to all programmers.

I will admit that I have been tempted to send copies to Redmond on more
than one ocassions.  I even tease my frends that work at Microsoft
about it.

I also have both Presto!Mail & Presto!Links running on a PIC1000 without

Actually, in develop (Apple's technical journal) there was an article about
the same subject that predated 'Solid Code' and 'Code Complete' by a couple
of years. It was a couple of pages long, and said essentially the same
thing that the books did. I don't remember which article it was anymore
(develop 9 springs to mind). I'll check at work tomorrow to find it.

In general, writing mission-critical code is a lot easier than writing code
for the general public, because the user isn't the focus; the information
is. Given that change of strategy, development (and by development I mean
UI development) becomes secondary.

While I agree that restricting the user's capabilities are a good thing,
when the conditions that cause problems aren't obvious, there comes a
tradeoff. Basically, in a non-mission critical app, the question becomes
"how much rope can the user have?". In a mission critical app, the question
is "do we need rope?".

Eventually, at least on limited resource devices, the user _will_ nuke the
OS. It happens on the Newton, it probably happens on the handhelds (I
haven't been monitoring the handheld stuff), and it used to happen on PCs.
The real question is "when can we have a handheld device that matches user
expectations formed on the desktop". Also, I suspect that most
manufacturers don't quite understand the data requirements of users (Palm
seems to, since it supposedly allows thousands of names; has anyone checked
this?). This leads to an OS that's optimized for a target size of
information, which is invariably too small.

Somday maybe we'll see a PDA that's completely immune to user abuse, but
that day isn't here quite yet. Heck, desktop OSs aren't immune....
