TidBITS#778/02-May-05
=====================
Mac OS X 10.4 is here, and this extra-large TidBITS issue shines
our own spotlight on some of Tiger's new features. First, Adam
asks the question, "Should you upgrade?" and Joe Kissell reviews
the installation process itself. Then we dig deep with Glenn
Fleishman's look at Spotlight and how it may change your
relationship to data, while Matt Neuburg reviews Dashboard
and Automator. We also note the releases of faster Power Mac G5
models and lower prices on two of Apple's Cinema Displays.

**Apple Speed Bumps Power Mac G5** -- Last week, Apple released
upgraded versions of the professional Power Mac G5 models,
increasing CPU speeds, adding larger hard drives, providing a
faster 16X SuperDrive with double-layer support, and installing
512 MB of RAM for each model. The single-processor 1.8 GHz Power
Mac G5 remains available for $1,500, but the stock dual-processor
models now ship at $2,000 (dual 2.0 GHz PowerPC G5, 160 GB hard
disk, ATI Radeon 9600 video card, and 3 PCI slots), $2,500 (dual
2.3 GHz PowerPC G5, 250 GB hard drive, ATI Radeon 9600, 3 PCI-X
slots), and $3,000 (dual 2.7 GHz PowerPC G5, 250 GB hard drive,
ATI Radeon 9650 with 30-inch Cinema Display support, and 3 PCI-X
slots). For comparison, the previous three steps were dual 1.8
GHz, dual 2.0 GHz, and dual 2.5 GHz. Also interesting is the new
16x SuperDrive with double-layer support that enables you to burn
up to 8.5 GB on a single double-layer DVD. All the dual-processor
systems ship with Mac OS X 10.4 Tiger.
<http://www.apple.com/powermac/>
The release date matches fairly well with the trends I identified
in "Take Control of Buying a Mac," which indicate that Power Mac
revisions tend to appear in the middle and end-of-year time
frames. This one comes slightly earlier than previous releases but
was undoubtedly affected by the Tiger release schedule. If Apple
stays true to form, I'd predict another speed bump toward the end
of this year, probably to 3 GHz, and a major upgrade in the middle
of 2006 since the Power Mac line tends to go three years between
significant changes. [ACE]
<http://www.takecontrolbooks.com/buying-mac.html>
**Cinema Displays See Price Cut** -- Apple also reduced prices on
its two smaller Apple Cinema Displays last week. The price of the
entry-level 20-inch model drops $200, from $1,000 down to $800,
and the 23-inch display drops $300, from $1,800 to $1,500. The
massive 30-inch display remains priced at $3,000, but the new dual
2.7 GHz Power Mac G5 supports the 30-inch display in its stock
configuration, eliminating the need for an additional video card.
Adding support to another Power Mac G5 configuration will run you
$350 for the necessary Nvidia GeForce 6800 Ultra DDL video card as
a build-to-order option; the standalone kit for existing machines
costs $500 or $600, and adding such a card fills one of your PCI
slots. Also providing built-in support for the 30-inch display
is the 1.67 GHz 17-inch PowerBook. [ACE]

Looking into the Eye of the Tiger
---------------------------------
by Adam C. Engst <[EMAIL PROTECTED]>
Well, it's done. Tiger is out, and all the speculation about its
much-ballyhooed features can at long last be put to rest. To
further that end, we're focusing on Tiger in several ways. For the
rest of this issue, and undoubtedly a number of articles in future
issues, we'll be writing about what's new, what it means, and how
well it all works. This week, for instance, you'll find articles
looking at the upgrade process, Dashboard, Automator, and
Spotlight.
But there's no way in TidBITS that we can go into the kind of
depth that readers want and that Tiger deserves. That's where our
Take Control ebooks come in with over 350 pages of painstakingly
researched and professionally edited advice about upgrading to
Tiger, customizing Tiger, users and accounts in Tiger, and sharing
files in Tiger (with Macs and other platforms). The ebooks are
good, they're inexpensive, they aren't copy protected in any way,
they come with free updates, and they're available now - weeks or
months before most other books about Tiger will appear. Tonya and
I, along with Joe Kissell, Matt Neuburg, Kirk McElhearn, and Glenn
Fleishman, worked our tails off for the last few months to release
all four ebooks simultaneously with Tiger (for overseas customers
who pre-ordered, we even made the ebooks available at 6 PM on
April 29th in local time zones around the world).
<http://www.takecontrolbooks.com/>
To kick off our coverage here in TidBITS, though, I'd like
to reflect on a question that likely didn't even occur to the
thousands of people who have bought the ebooks so far: Should
you upgrade, and if so, when? If you're on the fence about when
to upgrade, see if you fall into one of the following categories.
**The Hobbyist** -- I suspect that most people who consider the
Macintosh a hobby have already decided to upgrade, but if not,
I'd recommend ordering a copy. A new version of the operating
system means new toys, new features to explore, and a nearly
infinite amount of raw material for discussing with friends.
If you consider yourself a Macintosh hobbyist, then I'd recommend
an upgrade fairly quickly, if only so you can continue to feel
like one of the tribe.
<http://www.apple.com/macosx/overview/>
**The Filing-Challenged** -- If you're continually losing files on
your Mac, Tiger's Spotlight technology will become your new best
friend. For that matter, I'm betting that Spotlight will come
to the aid of anyone who has trouble figuring out where to file
documents, anyone for whom a rigid hierarchical filing system
never made much sense and who just ended up storing everything
on the Desktop. If you find yourself saying things like, "I put
it on the thing next to that other thing," Spotlight sweeps away
the artificial analogy of filing so you can think conceptually
when searching: "To whom did I write that letter? When did I
write it? What did it say?" My recommendation is to upgrade soon,
so you can at last throw some light into the darkness of your
hard disk organization.
<http://www.apple.com/macosx/features/spotlight/>
**The Scripter** -- Many people just use their Macs manually, but
others understand that one of the great uses of a computer is to
automate repetitive tasks. These people have long adopted macro
utilities like QuicKeys, iKey, and Keyboard Maestro, and many of
them have gone a step further in learning AppleScript. If you
fall into this category, Automator may be the next arrow in your
automation quiver, since it goes beyond scripting to give you
a visual interface to automating tasks without having to make
applications march about like marionettes. I suspect that the
possibilities offered by Automator will encourage such people
to upgrade in the relatively near future, even if the true promise
of Automator takes a while to be realized fully by third-party
developers.
<http://www.apple.com/macosx/features/automator/>
**Short Attention Span** -- Hang on, I need to check something
quickly. Right, the weather report for the Albuquerque and Santa
Fe areas for my trip this week is looking OK, so I can get back
to writing. If, like me, you find yourself needing to check in on
things or use small utilities - just a minute, I need to convert
Fahrenheit to Celsius so I can explain the current weather to a
friend in Australia - Dashboard and the plethora of Widgets it
will give you are a good reason to upgrade. That said, I wouldn't
be surprised if most of the things that Dashboard Widgets can do
in Tiger aren't also available in Panther thanks to Konfabulator,
so you don't need to upgrade instantly just for Dashboard.
<http://www.apple.com/macosx/features/dashboard/>
<http://www.konfabulator.com/>
**Driven by Deadline** -- Most people in this category have their
noses to the grindstone to finish projects, and honestly, it's
a hard sell to say that they should upgrade any time soon. The
reason is simple - they're so deep in Microsoft Word, or Adobe
Photoshop, or the like, that the specifics of the operating system
aren't likely to make that much difference in their day-to-day
work, and taking time out to install Tiger and come up to speed
on the new features isn't realistic. If you're one of these
workaholics, I do recommend that you upgrade, but not until Apple
has had a chance to release a few minor updates to eliminate any
initial problems, and then not until you have a clear opportunity
in which to install Tiger and spend some time gaining familiarity
with the new features.
**The Stick-in-the-Mud** -- "If it ain't broke, don't fix it" is
your motto, and Panther ain't particularly broke. I won't say
that you should upgrade, although in the next 12 to 18 months,
I expect to see new applications that take advantage of Spotlight
and Automator and Dashboard in interesting ways. If you find some
of those promises attractive, an upgrade may be worthwhile at that
point. Plus, if you buy a new Mac in the next year or so, you'll
end up with Tiger pre-installed, so you could also just put off
an upgrade until then.
**Tiger Details** -- To recap the details from Apple's initial
announcement, Tiger costs $130 for a single user license; the
Mac OS X Tiger Family Pack offers a five-user license for $200;
and the Mac OS Up-to-Date upgrade package costs $10 for those
who bought a new Mac on or after 12-Apr-05 (this offer ends
22-Jul-05). Note that Take Control ebooks come with a coupon
worth $5 off any order, including Tiger, at TidBITS sponsor
Small Dog Electronics.

<http://www.smalldog.com/>
Tiger requires a minimum of 256 MB of RAM (but please install
at least 512 MB) and will run on any Macintosh that has both
a PowerPC G3, G4, or G5 processor and built-in FireWire.
Tiger ships only on DVD media; if your otherwise-compatible Mac
has only a CD drive, you can either boot your Mac in FireWire
Target Disk Mode and install to it from another DVD-equipped
Mac, or you can pay Apple $10 (plus your local sales tax, which
you must compute) for a set of Tiger CDs. To order the CD set,
download the PDF form linked below, and package it up with your
payment, your proof of purchase, and your original Tiger DVD.
Apple says they will ship CDs within 24 hours of receipt if
they're in stock, but only via the U.S. Postal Service. So, it
might take two to three weeks from when you put your order in
the mail to receive your discs if Apple has them in stock.

Evaluating the Tiger Installation Process
-----------------------------------------
by Joe Kissell <[EMAIL PROTECTED]>
The first time I installed a pre-release version of Tiger, I was
worried. Unlike most people, who may be concerned about whether or
not their machine will work properly afterward, I had an entirely
different worry: who would need my ebook about upgrading if the
process works this well? Apple clearly paid a great deal of
attention to the installer, which is far better in Tiger than
in any previous version of Mac OS X. As a user, I was ecstatic;
as an author, not so much.
Now, some 43 installations later (and counting), both my
enthusiasm and my anxiety have diminished somewhat. I've gotten
to know the installer and its trusty sidekick, Setup Assistant,
rather intimately. Although the Tiger installation process was
full of pleasant surprises, I'm happy - I mean, sorry - to report
that there are still plenty of interesting quirks and questions
that may encourage you to spend $5 for some expert guidance in
the form of my new ebook, "Take Control of Upgrading to Tiger."
<http://www.takecontrolbooks.com/tiger-upgrading.html>
**Tiger Media** -- The first surprise is, as Adam noted in his
article, that Tiger ships only on DVD. To obtain a CD-based
installer, you must return your Tiger DVD to Apple, along with
$10, and wait for another package in the mail. I like the
simplicity of a single disc that includes the entire installer
(and Xcode Tools); it makes the installation go much faster
and reduces clutter and confusion. But if you have an otherwise
Tiger-compatible machine without a DVD reader, you may not feel
as happy about that decision.
**Installation Methods** -- Assuming you're upgrading an existing
installation of Mac OS X, the Installer, as usual, presents you
with three installation methods: Upgrade, Archive and Install,
and Erase and Install. I tried each of these methods numerous
times and under a variety of conditions. Although the default
choice, Upgrade, is generally reliable, you can achieve a much
cleaner (and slimmer) system with one of the other methods.
In the past, I've recommended Archive and Install for most people,
as it provides a happy medium between the simplicity of Upgrade
and the robustness of Erase and Install. I assumed I'd be
reiterating the same advice this time (as numerous other Mac
Web sites have done). Not so: much to my surprise, I found that
Erase and Install - if used in just the right way - offers a
significantly faster, more effective, and safer way to get your
old stuff into your new system as long as you have good backups.
I urge everyone to have at least one, if not two, backups before
erasing your hard disk; if you're uncertain of the best ways
to make reliable backups, see my "Take Control of Mac OS Backups"
ebook.
<http://www.takecontrolbooks.com/backup-macosx.html>
The key to this new way of thinking is Migration Assistant
(the same tool that Apple provides to facilitate moving files
from an old Mac to a new one). You don't have to run this
program separately; all its capabilities are integrated into
Setup Assistant under the auspices of "File Transfer." After you
perform an Erase and Install and restart, Setup Assistant offers
to transfer your files and settings from another Mac or partition.
As long as you have a bootable backup of your old system on another
partition - or, preferably, a second internal or external hard
disk - Migration Assistant does a brilliant job of integrating
your old files into Tiger. It does not do a perfect job - some
manual copying or reinstallations will still be necessary - but
the amount of extra work you'll need to do is far smaller, and
less scary, than what would be required after an Archive and
Install. I cover all the details of restoring files (for both
methods) in "Take Control of Upgrading to Tiger."
**Optional Software** -- During installation, you can select or
deselect several optional software packages. I found Apple's
default choices rather odd. For example, language translations,
which take up over 1 GB, are all enabled by default - yet
relatively few people need to be able to use Mac OS X in more
than one language, and almost no one needs to be able to use it
in every available language. Overall, there are fewer options
to choose among than under Panther. You cannot, for instance,
deselect the BSD Subsystem, as you could in earlier versions
of Mac OS X (a good thing, as many third-party applications
rely on it).
**After the Installation** -- After installation, Setup Assistant
takes you through the usual process of selecting a user name and
password (if necessary), configuring your .Mac account (if you
have one), registering with Apple, and so on. This portion of
the process seemed much clearer than in the past. On your next
restart, however, you may discover that important startup items
were disabled due to changes in file permission requirements.
A more helpful approach would have been to fix these items'
settings automatically, or at least indicate on the first launch
of Tiger that they are unavailable and why they were disabled.
**Minor Shortcomings** -- As much improved as the Tiger installer
is, I could certainly wish for more-intelligent behavior.
For example, both Upgrade and Erase and Install (if followed
by File Transfer) leave all your login items (formerly known
as startup items) enabled; some of these caused problems for me
because they pointed to old applications that are incompatible
with Tiger. A better tactic would be for the installer to disable
those items - but provide an easy way to turn them back on,
one by one. Similarly, File Transfer copies some applications
and preference panes to your new system but not the kernel
extensions they frequently rely on, leaving you with half-
installed software that doesn't work, but no clues as to why
it doesn't work. Although the installer helpfully warns you about
some of these (Virex, for example), in most cases it does not.
And I encountered some interface oddities, especially in the
File Transfer portion of Setup Assistant. For instance, it's not
clear that "partition" means "partition or external hard disk,"
and the screen where you choose individual components of your
old system to transfer doesn't provide enough information to
make informed decisions.
**You Can Take Control** -- On the whole, the Tiger installer
still gives me relatively warm and fuzzy feelings, these few
gripes notwithstanding. Even at its best, though, it leaves plenty
of questions: What steps should I take to prepare for an upgrade?
Which upgrade method is best for me? Should I partition my hard
drive first, and if so, how should I do it? What files do I need
to copy after Archive and Install? How do I fix the things that
don't seem to work afterward? You can find the answers to these
and many other questions in "Take Control of Upgrading to Tiger" -
an 87-page ebook that details everything you need to know about
the upgrade process, with free updates as more information becomes
available.

Spotlight on Spotlight
----------------------
by Glenn Fleishman <[EMAIL PROTECTED]>
Much will be written about Spotlight, one of Tiger's marquee
features that takes system-wide search from a time-consuming
annoyance to an efficient part of everyone's workflow. In fact,
Spotlight works so well that the idea of filing email, files,
and other data will eventually disappear - but not quite yet.
You'll read a lot about the general features of Spotlight: you
can find any text in any file quickly, or use it to pinpoint menu
items in System Preferences. I'd like to tell you quickly about
how Spotlight works and then delve into areas you probably won't
hear as much about elsewhere. I'll conclude with musings on how
Spotlight might free us from the tedium of forcing organization
on top of what we create.
**Spotlight in a Nutshell** -- Spotlight's approach is simple:
everything is indexed quickly and efficiently in an ongoing
manner. Install Tiger and reboot, and the first thing the
operating system does is index your hard disk. In multiple test
installations, I didn't even notice the indexing taking place,
although some users report 50 percent of their processing power
devoted to the task. You can't use Spotlight until this initial
index is done, but clicking the blue Spotlight icon in the upper
right of the system menu bar will reveal how long Tiger thinks
it will take to be finished. A pulsating dot in the center of
the magnifying glass icon lets you know indexing is taking place.
When it's done, Tiger automatically modifies the index for every
changed document and adds every new document to it. This happens
quietly as well. Let me restate this in case it didn't sink in:
Spotlight doesn't run a full re-index of your hard drive every
night requiring you to leave your computer on or causing loud
drive access noises in the wee hours. All other overlay indexing
programs and previous Apple attempts required that kind of churn.
I haven't stress-tested Tiger yet by, say, using Automator to
create 1,000 one-megabyte-sized files of random text, but that
would be a good way to see Spotlight's ongoing indexing in action.
By integrating index updates into the operating system at the
filesystem level, Tiger avoids patching the system at a low level
(always dangerous), the above-mentioned overnight reindexing,
and subset indexing that omits potentially useful data.
Apple also seems to have pulled off a neat trick: using some kind
of optimized index to produce some results right away, Spotlight
searches start running as soon as you start typing. By the time
you finish typing, either through predictive word finding or sheer
good programming, the search is almost done.
I've found Spotlight incredibly zippy on a 1 GHz 15-inch aluminum
PowerBook G4 and a dual 1.25 GHz Power Mac G4. I'll be curious
to hear about how it feels on the lowest-end machines that Apple
supports.
Spotlight is available at any time from the upper right by
clicking its icon, or pressing Command-Space. It also appears
in every Finder window by default, and, most critically, within
any Open and Save dialog box. No more navigating to find files to
open! No more navigating to find the right folder to save! I will
still love and cherish Default Folder, but it will be much less
important to my future workflow.
<http://www.stclairsoft.com/DefaultFolder/>
Apple has made Spotlight available from the command line, too.
The mdls command lets you see the metadata associated with any
file. The mdfind command is essentially a Spotlight search.
<http://developer.apple.com/macosx/tiger/spotlight.html>
**Narrowing Spotlight Searches** -- Spotlight rewards those that
need more sophisticated searches by allowing you to refine phrases
that constrain date and time, file names, and other metadata.
Metadata is data that describes data, like the last modified time,
the F-stop of a camera, a QuickTime movie's format or length,
or the photographer's name embedded into a TIFF image's header.
Most searches will start with keywords, but you will quickly want
to drill into subsets if you have many results. Apple has built
a nomenclature for searching that they haven't yet exposed well -
the special words that you can use to restrict searches.
Unfortunately, these words aren't currently documented anywhere
on their site or within Spotlight Help in the release of Tiger.
You can experiment with restrictive phrases. Apple's page on
Spotlight suggests that you might add "Date:yesterday" after
keywords to find just files created in the last day. If you
wanted to find all images created yesterday you could enter
"Date:yesterday Kind:image". I expect this nomenclature will
be fully documented over time. These restrictive words will be
especially useful in Open and Save dialog boxes, where Spotlight
could produce daunting results.
<http://www.apple.com/macosx/features/spotlight/>
The capability to make use of some of the increasingly rich
metadata produced by digital media devices is a boon. Imagine
finding all pictures you've taken on a particular Canon camera
model at a specific resolution. Right now you need to use
a cataloging program such as iView Media Pro and keep that
catalog constantly up to date.
There's another way to use these restrictive add-ons without
knowing Apple's secret narrowing words - via Smart Folders.
**Folders as Search Results** -- A couple versions of Entourage
ago, Microsoft added pseudo-mailboxes that were actually search
parameters presented as a mailbox. Unfortunately, for those of
us with zillions of messages, a search took an unbelievably long
time with the search engine Microsoft used at the time.
Spotlight has taken that concept and extended it to the Desktop in
the form of Smart Folders, which are essentially the live results
of a set of search parameters you define. Spotlight's performance
is good enough that you don't notice the fact that a Smart Folder
is populated dynamically.
Along the way, Apple removed Panther's advanced searching from the
Finder; selecting Find from the Edit menu effectively creates a
new Smart Folder (using the same dialog as the New Smart Folder
command) that isn't yet saved. To create a search that narrows
down beyond keywords, you either learn the incompletely documented
nomenclature described above, or use Smart Folders.
When creating a Smart Folder, the default parameters are Kind:
Any, and Last Opened: Any Date. The buttons above the search
parameters list Servers, Computer, Home, and Others. If you
leave it set to Home, the search is restricted to the current
user's Home directory. I prefer setting it to Computer to take
full advantage of Spotlight's capabilities, and because I keep
documents and other files stored throughout my hard drive, not
just in my Home directory as Apple would prefer. (Click Others
to add or remove specific folders or hard drives.)
You can create a Smart Folder, too, in any Finder window by typing
a search in the Spotlight field. That Smart Folder doesn't show
the default scope of Kind and Last Opened, but you can click
the plus sign at the upper right next to the Save button to
add bounds.
Smart Folders let you mix the contents of the Spotlight field, in
which you might enter keywords, with restricting conditions. Click
the plus sign next to any condition to add more. Select the pop-up
menu that's the condition's name and you can select one of several
favorite conditions, or select Other.
In Other, you will see the full range of predefined metadata
that's supported in Spotlight. For instance, select URL and
you can choose to find any document that contains that URL.
Check the Add to Favorites box and that attribute now shows
up in the condition pop-up menu.
I don't want to turn this into 10,000 words on Smart Folders,
but there's more: you can show the top 5 or all results for
a given document category; sort by date or kind; click the
"i" button next to a file to see a summary of its information;
view PDFs by a thumbnail of their first page; show images;
and so forth.
**Rethinking Filing** -- Filing is a tedious activity that
computers were supposed to save us from, right? That's why
I was so excited to see Creo's Six Degrees program a few years
ago. Six Degrees integrated with certain email programs under
Mac and Windows so that recipients, subject lines (discussion
threads), and attachments were the three points of a triangle.
You could rotate your email-world around to view it through
the window of who you corresponded with, what you talked about,
and what files were involved. (The product was sold to Ralston
Technology Group and is now marketed as Clarity.)
<http://www.ralstontech.com/>
Spotlight expands that notion far, far beyond those modest but
significant goals. Six Degrees was trying to free people from
ever having to decide in which mailbox an email message should
be stored, and in which folder a file belonged.
I don't think Spotlight yet allows us to break down all barriers
and use one giant email folder to store all messages, and one
giant Finder folder to store every file we create or receive.
But, it is moving us closer to what I think people actually want
from their computers: not to spend a good percentage of time
categorizing.
Perhaps it will take some time yet, but I perceive the future
of information to be much more amorphous. Instead of discrete
information chunks, every graphic, letter, report, presentation,
movie, or other project piece is just a blob in the middle of some
kind of data medium that we navigate through in many different
ways: by date, by content, by visual presentation, by keywords,
by attributes.
That is, the interface to our data is no longer the worn-out
metaphor of files and folders, but a rich interactive approach
that mediates between an underlying structure we don't need to
understand and our desire to find things by the way we remember
them. Say goodbye to descriptive file names, for instance.
I didn't come up with this way of viewing the future of desktop
information, nor did Apple. David Gelernter, a Yale University
computer science professor, has been talking about this since
at least 1991. Although a company he founded to implement these
ideas seems to have disappeared, his ideas are well represented
in a 2003 interview: read the section on Information Beams.
<http://java.sun.com/developer/technicalArticles/Interviews/gelernter_qa.html>
In that interview, he said, "When I acquire a new piece of
'real-life' (versus electronic) information - a new memory
of (let's say) talking to Melissa on a sunny afternoon outside
the Red Parrot - I don't have to give this memory a name, or
stuff it in a directory. I can use anything in the memory as
a retrieval key."
Spotlight is probably the first mainstream operating system or
program to take a big step towards Gelernter's humanist view
that maps how we think to what we have stored.
Introducing Dashboard
---------------------
by Matt Neuburg <[EMAIL PROTECTED]>
Think of Tiger's new Dashboard feature as a constantly running
pseudo-application. It is constantly running in the sense that
you cannot quit it; it is a pseudo-application in the sense that
it isn't a distinct process (it's really an aspect of the Dock)
and in the sense that (like the Dock) it behaves differently from
any other application.
Dashboard is always in one of two states. When it isn't the
frontmost application, it is invisible and inert. When it is
the frontmost application - you can summon it either by pressing
a user-configurable keyboard shortcut (F12 by default) or by
clicking its Dock icon - it takes over the entire screen, covering
all windows, the Desktop, and the menu bar with a dark haze,
rather like London in a Sherlock Holmes episode. Gleaming in front
of this haze are some roughly rectangular areas of bright color:
these are the Widgets to which Dashboard plays host. All you can
do when Dashboard is frontmost is interact with a Widget - look
at one, drag one around, click one. All the while, your other
applications remain active in the background. When you're done
using Dashboard, you click somewhere in the haze, and it and
all the Widgets vanish, and you can proceed to use your computer
in the normal way.
A Widget is itself a sort of pseudo-application. It's effectively
just a window, and a non-standard window at that: it has no title
bar, no Aqua-style interface, and no menus. In fact, there are
essentially no standard rules of interface for a Widget; it is
effectively painted on the screen in any style and shape the
developer fancies. Behind the scenes, a Widget is more like a
piece of a Web page than anything else; it is implemented not
with Carbon or Cocoa but with HTML, CSS, and JavaScript. A Widget
file is a bundle; a dozen or so Widgets are installed by default,
in the /Library/Widgets folder, and you can actually open a Widget
bundle in the Finder (using the Show Package Contents contextual
menu command) and read its "code." Third-party Widgets, which
are already becoming available from various Web sites, can be
installed here or in your user's ~/Library/Widgets folder.

<http://www.dashboardexchange.com/widgets/>
Your installed Widgets constitute a smorgasbord from which to
choose; which ones actually appear when you summon Dashboard is
up to you. You click a big "+" at the lower left of the screen
to reveal the Widget Bar; it displays icons for all your installed
Widgets, and you click or drag an icon to instantiate it in the
Dashboard main area. Similarly, when the Widget Bar is showing,
Widgets in the main area have an "x" that you can click to dismiss
them (and when the Widget Bar is not visible, you can reveal a
Widget's "x" by holding the Option key and hovering the mouse
pointer over that Widget). It is legal and useful to instantiate
a particular Widget more than once. For example, the Clock widget
shows a clock set to a specific time zone, so to show the time in,
say, both Los Angeles and Indianapolis, you instantiate the Clock
widget twice, and set one instance to Pacific Time and the other
instance to, uh, whatever weird time zone they think they're in
in Indianapolis.
The Dashboard architecture - where either Dashboard is absent
and you can't work in it at all, or else it is frontmost and
you can't work anywhere else - may seem rather restrictive,
especially in comparison to Konfabulator, which permits its
Widgets to be interleaved with ordinary application windows.
However, it all makes more sense if you think of a Dashboard
Widget as something you glance at, or work with for a just a
moment, and then dismiss. If you always need to see a clock,
use the System Preferences (Date & Time) clock. If you need to
glance at a clock now and then and then get back to work, use
the Dashboard clock. From this perspective, users may well be
pleased that when Dashboard is not frontmost, its widgets occupy
no screen real estate (like a window), no Dock slot (like an
application), no menu bar space (like a status menu), and no
CPU time. On the other hand, the single-layer architecture
decidedly favors user with big monitors; my 12-inch iBook
feels crowded when just half a dozen Widgets are present.
<http://www.konfabulator.com/>
The decision to base Widgets in HTML and JavaScript is more
controversial. From a user point of view, I find the lack
of uniform interface decidedly off-putting. When I see an Aqua
window, I know at a glance what its parts and components are for,
but every Widget is different; you don't know what regions are
clickable (button-like) or draggable (title bar-like) until you
try it. And they're funny-looking; they don't look like one
another or like anything else we're accustomed to in Mac OS X.
From a programmer's point of view, reactions will vary. If you're
already a JavaScript maven, you may be delighted. But compared
to the elegance and convenience of Cocoa, the HTML and JavaScript
approach to programming strikes me as messy; my own MemoryStick
application would make a good Widget, but having studied the
Dashboard programmer documentation, the chances that I'd ever
do the massive rewriting involved are vanishingly small. The way
to know whether Dashboard is really a useful and productive part
of Tiger is to wait and see, as Tiger matures, what kind of
Widgets get written and whether users really use them.

Meet Automator
--------------
by Matt Neuburg <[EMAIL PROTECTED]>
The history of the Mac is paved with Apple's attempts to
enable ordinary users to tap the programmable power of their
own computers. Apple events allowed applications to tell each
other what to do. AppleScript allowed users to harness Apple
events in an English-like programming language. AppleScript Studio
allowed an AppleScript script to be wrapped in a Cocoa interface.
But the Grail has remained elusive. The vast majority of users
don't want to deal with a programming language. Pre-written
scripts exist, but what if you don't know that, or can't find
one that does what you want? The problem is that it's impossible
to know in advance what you, the user, would like to do - that's
the point of putting programming power in your hands in the first
place.
<http://macscripter.net/>
The challenge, then, is to provide you with the "building blocks"
you need, in such a way that _you_ can assemble them, _yourself_,
to do what _you_ want - without your having to know a scripting
language. With Automator, Apple rises to this challenge.
**A Piece of the Action** -- Automator's "building blocks" are
files called Actions. Tiger comes with over 200 Actions pre-
installed; they do things such as create an iCal event, compress
the images in a PDF, or rename the files in a folder. When you
start up Automator, you're shown all the installed Actions;
using simple drag-and-drop, you arrange the ones you need into
a top-to-bottom sequence called a Workflow. You can then run the
Workflow to execute the sequence in order; you can also save the
Workflow so that you can conveniently run it again later, send
it to your friends, and so forth.
It isn't just the sequential execution of Actions that gives a
Workflow its power: an Action may accept input from the previous
Action in the sequence, and may produce output which is passed
to the next Action in the sequence as _its_ input. Furthermore,
an Action can have an interface, where you specify ancillary
settings. For instance, in the Action that sets the iTunes volume
(loudness), the new volume value comes from a slider in that
Action's interface. You can set that slider in advance, as you're
creating the sequence within Automator; alternatively, you can
postpone the decision and have the slider presented to you in
a separate window at the time the Workflow actually runs. In some
cases, indeed, an Action's entire purpose is to request input
from the user at runtime.
A Workflow thus involves a clever interplay between data flowing
from Action to Action, on the one hand, and the user's input,
on the other - where the user's input can be provided in advance
or as the Workflow runs. Here's an example to illustrate. Suppose
I have a folder of 100 images, and I want to rename them Image001,
Image002, and so forth. (That's genuinely useful; people
frequently ask how to do this sort of thing.) An Automator
sequence to accomplish this might go as follows:
* Step One: Ask the user where to create a new folder. (The idea
is that we're going to copy all the files into this folder before
renaming them, just in case something goes wrong.)
* Step Two: Ask the user for the source folder that currently
contains the image files.
* Step Three: Get a list of all the files in that folder.
(This step accepts as input the folder from the previous step
and produces as output all the files in that folder.)
* Step Four: Ask the user where to copy those files to - the user
should specify the folder created in Step One - and copy them.
(This step accepts as input the list of files from the previous
step and produces as output the copied files.)
* Step Five: Rename the copied files. (They are the output from
the previous step.) The Rename Files Action presents lots of
options for how the renaming should work; one of these is a
constant prefix (with the user sets as "Image") followed by
a sequential suffix with a fixed number of digits (which the
user sets as 3, to get suffixes like "001").
Ease of use is a slippery concept, but that sequence really was
easy to create. I set it up in Automator spontaneously, without
forethought - when I started, I wasn't even sure what I wanted
to do, or what Automator would let me do. When I introduced the
Rename step, Automator itself suggested I add the Copy step before
it, as a safeguard; through warnings of this sort, and by checking
to see that one Action's output is legitimate input for the next,
Automator assists the naive user.
An Action is a terrific way to package scripting functionality.
It takes about two minutes to turn an AppleScript script into an
Action. As an AppleScript programmer, I'd much rather send you
an Action than a bare script, because you can incorporate it into
your own sequences and customize it through its interface without
having to know any AppleScript yourself (and without relying on
me to modify it for you). It is also possible to write an Action
in Objective-C. Furthermore, an application bundle can contain
Actions, which automatically make themselves available to
Automator without further installation; thus, for example,
by simply running BBEdit 8.2 (a free update for BBEdit 8
customers), you'll see two dozen text-processing BBEdit Actions
magically appear in Automator.
<http://www.barebones.com/support/bbedit/updates.shtml>
<http://www.barebones.com/support/bbedit/current_notes.shtml>
Given all this, I expect to see a spate of further Actions in
the near future - big developers will bundle them into their
applications, scripters will use them to repackage their existing
scripts. As that happens, end-users, I suspect, will quickly
discover that Automator is the fulfillment of a dream: at long
last, anyone can program the Mac.

a special thanks to our authors for working so hard to help us
release all four ebooks simultaneously with Tiger. Next milestone:
10,000 sales!
**Take Control of Your Inner Control Freak** -- No, it's not
really one of our upcoming titles, but the clever folks at Joy
of Tech used it in a comic poking fun at Apple and Steve Jobs
over the recent fuss surrounding Apple's removing Wiley books
from Apple Stores in retaliation for what Jobs presumably
believes is an unflattering biography.
