After many years together, my Linksys WRT54G and I have parted ways. In its place, I'm now using an 802.11g-based Apple AirPort Express with AirTunes that was passed along to me. Besides not wanting to fork out the extra beans (c'mon, who here isn't saving up money for an iPad) for a shiny new 802.11n Airport Express, the devices living in my current wireless ecosystem are more g-leaning. That, and I don't really need the speed of 802.11n or the ethernet cable connection afforded to me by the WRT54G.

Or so I thought.

Last week, the fine Facebook folk let us know (via the Facebook Help Center) that you can now sign in to Facebook's chat service using iChat. Of course, the free Adium client has directly supported Facebook chat since version 1.3 (released in 2008), but this step opens up a much wider range of clients for the service.

Facebook's chat service is powered by the Jabber/XMPP open source chat protocol. Many networks (such as Google Chat) rely on Jabber, and for this reason chat clients like iChat and Adium allow for the setup of a generic Jabber account to facilitate the widespread use of Jabber.

The process is simple. First, create a new generic Jabber account pointed at Facebook's Jabber server. The username to use is your Facebook username (which you can find on the Account Settings page) and the password is the same as your Facebook login password. Next, point the server to "chat.facebook.com," configure the port to 5222 and un-check the box for "Use SSL."

After it's all said and done, you should be able to communicate with your Facebook friends using iChat without being logged in to Facebook with a browser.

There are, roughly, several billion kinds of microphones and headsets, all of which can theoretically be used on your Macintosh to let you voice chat over iChat or Skype. The problem is that a fair percentage of them fail to work exactly right, just out of the box.

Fortunately, there are several tricks that can help you analyze why your audio chats aren't working quite right. Here's a quick run-down of the steps you should take.

Start in System Preferences. The Sound preferences pane lets you select devices for your sound input and output. And, importantly, it lets you test your input device and adjust its volume. After attaching your mic to your Macintosh, use this pane to set-up and test.

We here at the TUAW headquarters rely pretty heavily on our iPhones when we're away from our desks. This is especially true for the lucky ones on the floor at Macworld 2010. Sometimes however, our little pocket computers go haywire and refuse to respond to our commands.

To force quit an unresponsive app all you have to do is press and hold the Sleep/Wake button until you see the red slider. Normally, this is what you would do to power down your iPhone or iPod touch. In this case however, when the slider appears, release the sleep/wake button and then press and hold the Home button. If it works correctly, your iPhone will forcefully quit the unresponsive app and return you to your home screen.

I have found this especially useful on the rare occasion that Mail begins to choke on my multi-thousand message inbox. Sometimes this simple kick in the pants is all that is needed and is a lot quicker than a hard reboot followed by the waiting required during boot up.

I love home theater. I love it so much that I have a real one in my house with a nine foot 2:35:1 screen and enough clean sound to be IMAX's little brother. Now Gary Katz has taken the opposite approach and built an absolutely gorgeous Liliputian theater out of a shoebox, some rubber cement, laser printed graphics and a very sharp knife. Take a look at the hand in the picture above and you'll be able to see the scale. Open the doors and you'll see a quite realistic-looking theater. And what powers the magic? An iPhone of course, which is cleverly slipped into a slot at the back of the shoebox. This little jewel box of a theater is a work of art in itself and the attention to detail is remarkable.

I can easily see an audience of green army soldier toys happily watching Toy Story. I think they'd like it much more than Ratatouille.

Read on to see the theater in action and then check out the inevitable 'making of' documentary.

By default, movies and TV shows in the iPod portion of the iPhone and iPod touch play in landscape view. The biggest change with respect to video orientation came about with iPhone OS 2.0, which provided the option for landscape-right viewing (that is, with the volume and silent/vibrate buttons facing up). While most videos could, and should, be viewed in landscape, there are times that call for a portrait perspective -- for example, when placing your iPhone into a dock, which is what I do when working out.

Getting your iPhone to play a movie or TV show in portrait mode requires a simple change in the video's tag, from TV Show or Movie to Podcast. Simply right-click on the file and select "get info "(or you could use the Command-I shortcut). Then, in the "Media Kind" section within the "Options" tab of the video, select Podcast. Now, the videos will show up in both the Podcasts and Videos section of the iPod portion on your iPhone.

Obviously, this isn't something you'd want to do with every movie or TV show in your library. So, to revert the file back to its old self, you'd want to follow the same process and change the video back to a TV show or movie.

One gem in Mac OS X that sometimes gets glanced over is the Services menu. Lots of readers may not know yet that Snow Leopard brought with it the ability to create your own customized service in Automator -- in other words, you can get additional selections on a contextual menu when right-clicking within a certain context, say a file within a Finder window. To create a customized service, all you have to do is launch Automator and select "Services" from the "Choose a template for your workflow" window, and then insert your own service from there.

Here are five customized services for you to install on your own Mac.

A friend's MacBook had slowed down to a snail's pace. Despite looking everywhere for the issue, streamlining everything I could, and yelling at it, it failed to accelerate to usable speed. So I recommended we start from scratch and build it back up with only the things she was using, free of all the other downloads and aborted installs of various software she never used or cared about. It also housed a prior system, and a PC migration from a few years back. All told, the computer was a bloated, duplicated whale of files and applications for what was essentially a light-load writer's computer.

So I backed up the essential parts of her system using Time Machine: documents (including her novel and decades of prior writing, published and unpublished), ten years of family photographs, a 41GB iTunes library, among other things, and then....backed it up again elsewhere, outside of Time Machine.

And again.

And just for good measure, once more time, to yet another drive. I wasn't going to be the (ex-)friend who lost her novel.

What I wanted to do was do the ol' "erase and install" that prior system software discs allowed you to do. But clicking around Snow Leopard left no obvious method for this. But instead of booting Snow Leopard while inside of Mac OS X, if you just directly reboot the computer off the disc itself (holding down the "c" button after the system chime, letting go when you see the Apple logo) you get a few more options. Once you've gone into the installer program, you'll see "Utilities" at the top, and if you select Disc Utility, you can see your hard drive. If you click on "erase" (like I did, with one hand over my eyes) you can wipe the drive clean with various security options, and then you can do a fresh install of Snow Leopard on your computer on a pristine hard drive.

Once you've done that, you can either transfer your files back in directly, or use the installer program's built-in migration utility to restore any or all files from Time Machine.

And now? The world awaits the Next Great American Novel, untragically unlost by yours truly.

I've previously demonstrated how to use LaTeXiT to create and display complex math formulas and other symbols, and thank you readers for the additional recommendations!

While providing a means to display almost every imaginable existing symbol or character, a LaTeX-based solution may prove too complex and unnecessary for some. For the less "mathletic," Mac OS X's built-in character viewer is one of the easier ways to display characters of all sorts.

To enable the character viewer, open Mac OS X's System Preferences and select the "Language & Text" icon. Once there, click on the "Input Sources" tab and place a checkmark next to the "Keyboard & Character Viewer" box and "Show input menu in menu bar" box. The Keyboard & Character Viewer is now accessible on your menu bar.

Now, displaying special characters on your document, email, or whatever it is you're working on is just a drag and drop away.

Imagine if, as Steve Jobs moves through each slide of his Keynote presentation, he also has the telepathic powers to automatically tweet information related to the slide.

But even the almighty Steve Jobs can't do that.

Fortunately for him, there's Keynote Tweet. An open source AppleScript app, Keynote Tweet will automatically tweet the text from your presenter notes (accessible by clicking on "view" and selecting "show presenter notes").

Keynote Tweet was exposed to me while reading a piece by IDEO Labs' Gentry Underwood, who highlights the idea of large presentations increasingly occurring within the context of a backchannel in which audience members are responding to what's being presented.

Getting Keynote Tweet up and running is fairly straightforward. Simply download the app, and then add the following entry into the Keychain Access app:

• Keychain Item Name: http://twitter.com
• Account Name: Your email address
• Password: Your Twitter password

Now, with the Keynote Tweet app running, any text between the [twitter] and [/twitter] tags will automatically tweet when that slide is displayed (while in slideshow mode).

For example, "Jay Leno lacks the charm, wit and red headedness of Conan O' Brien" will be tweeted the moment I reach the slide showing the percentage of people that hate Jay Leno.

Keynote Tweet is available as a free download here.

I'm the iTunes music pharmacist for my family's iPod and iPhone music libraries. In short, what this means is that, whether it's due to "getting sick of hearing the same thing over and over when I'm running" or wanting a new song or album on their iPod, they come to me when they want their music refilled. Which is fine and dandy. I'm more than happy to do this, and have my trusty ol' 17 inch iMac loaded with everyones' music on it (except mine, which is loaded on my MacBook Pro).

From the 3rd generation iPod classic to the iPhone 3G S, and from The Arcade Fire to ZZ Top, there exists an eclectic iPod and music mix in my family. How I would sync music for each person varied on a case-by-case basis, and usually took shape in syncing specific folders, playlists, smart playlists, and genres. For the iPod shuffle, however, I would typically click on the "music" within the device and choose playlist-based "autofill."

This morning, my sister brought over her shiny new third generation iPod shuffle. And to my surprise, it, unlike its predecessors lacked the "autofill" feature. Or so I thought.

After spending a half hour or so creating a size-limited smart playlist with random songs, I said to myself, "Self, there's gotta be an explanation for this. Surely, the folks at Apple wouldn't leave out something as important as autofill."

And they didn't. They just put it in a different place for the third generation shuffle, and have now extended the feature for all iPods and iPhones.

To enable autofill on your iPod or iPhone, click on "summary" tab for your device (in the "device" section of iTunes). Then place a checkmark on "manually manage music [and videos]."

Now here's where I got lost and confused, and I don't want you to pull out your hair like I almost did mine just because I didn't read the Apple support forums carefully enough. Except for first and second generation iPod shuffle models, the autofill option for all iPods and iPhones is activated by expanding the device (by clicking on that little triangle to the right of it) to reveal its media folder hierarchy. Then, you'll want to click on "music," and now you'll see the autofill option in the bottom left hand corner. The whole time, I thought it'd be located on the "music" tab within the device, much like how it's on the "contents" tab on the second generation iPod shuffle.

Autofill is now available for all iPods and requires iTunes 8.1.

The more you know...Dun, dah, duh, ding.

The iWork suite of apps (Pages, Numbers and Keynote) play nice with each other -- for the most part. Objects such as shapes, text boxes and tables created in one app can easily be copied and pasted onto another and retain their styles. Even an image with an instant alpha filter applied will retain its transparency when pasted onto another iWork app. However, the iWork apps don't always play nice with each other when it comes to charts.

In particular, copying a chart created in Numbers and pasting it onto either a Keynote presentation or Pages document doesn't always bring the chart's legend with it respective to how it looked in Numbers. Sometimes, the legend may be misaligned, and sometimes it may even show up on a completely different page in the document.

To address this annoyance, just highlight all of the elements (the entire chart and the legend, or anything else you want retained) of the chart that you'd like to copy. Then click on Numbers "Arrange" menu and select "Group" (or hit Command-Option-G). Now, the legend of your chart retains its alignment when pasted onto either a Keynote presentation or a Pages document. To alter or undo this, just select "Ungroup" (Command-Option-Shift-G) from the same file menu.

The iTunes Store and App Store have mastered the art of the impulse purchase. "Only two bucks? Sure, why not?" The good news is that you can send a song, album, movie or TV show to a friend just as easily.

Let's start with music. First, find the album or song you'd like to send. If you're sending a song, you'll see a drop-down arrow next to the track's "Buy" button. Click it to reveal the menu at right, then select "Gift this song."

You're brought to a new screen (in the gallery below). From there you only need to enter some information, click continue and you're done! Your recipient will receive a nice email message with a download link. The process is the same for albums, individual TV shows, audiobooks (though the "Gift this audiobook" looks different) and movies.

Note that you can't gift entire TV seasons (bummer) or iPhone/iPod touch apps. However, you can opt to share a link to an interesting app. With the app selected, click the same drop-down button to reveal the "Tell a Friend" option. The same is true of Podcasts - hit that "Tell a Friend" button to let everyone know what you're listening to. With just a few clicks, you can share your favorite content with anyone you want!

Text replacement: it's one of Snow Leopard's really cool features. With it, you can type abbreviations and they'll automatically expand into full text. You can convert your most common phrases into just a few keystrokes, and let Snow Leopard take care of the rest. Here's a quick summary of what you need to do to make text replacement work for you.

Creating Macros in System Preferences.

Open System Preferences (it's in the Apple menu at the top of your screen) and navigate to Language & Text > Text. There you'll find a Symbol and Text Substitution list. Click the + button to add a new item. For this example, put (tuaw) into the Replace column and The Unofficial Apple Weblog into the With column. Leave the box to the left of these items checked.

So why use the parentheses? Strictly speaking, they're not necessary. You can define text substitutions on any set of characters, as shown in the screen shot below. What these parentheses do for me, is that they distinguish between when I want to type TUAW and not have it expand, and when I want the abbreviation to transform into the full Weblog name.



Enabling Text Replacement

Text replacement works on a per-application basis. Many applications default to this feature being off. To make text replacement happen, right-click within any text entry area such as a composition window in Mail or the text entry field in Colloquy, etc. The contextual menu provides a Substitutions submenu. Make sure Text Replacement is checked. If it is not, select it to toggle the option from on to off or off to on.



Applying Text Replacment

The big secret to making text replacement happen, once you've defined the shortcuts and enabled Text Replacement in the contextual menu, is the space key. Snow Leopard does not apply the shortcut replacement until it detects you have finished typing a phrase. Only then does it perform its internal look up and substitution.

Also prepare to wait a second or so. The replacement text often lags behind your typing. So go ahead and keep entering text. The operating system will catch up and perform its substitution work without your oversight.
