Here's another augmented reality iPhone app that might be slightly more useful for those of us outside of London than the Nearest Tube app we showed off the other day. TwittARound is a Twitter client (currently in beta) for the iPhone that uses your location info, compass, and the 3GS' video camera to place tweets close to your location in a realtime video view, so that the effect you get is like pop-up notes on the landscape. Very cool indeed. Unfortunately, it seems many of these AR (augmented reality) apps may never see the light of day, as some developers are saying Apple doesn't provide any public API calls for the live video (hence this petition from the burgeoning AR community).

There are other issues here too, though, even if Apple does open up all of the APIs needed for a project like this. Twitter doesn't actually include location information with each tweet, so what you're actually seeing (I'd imagine) is the location of each Twitterer. What you'd like to do with an app like this is walk around and use it to get information about what you see (look through the app at a line outside a concert hall, for instance, and see people talking about who's playing inside). But unfortunately, unless they have some way of seeing exactly where those tweets come from, they'll all still be from each Twitterer's location, not where the tweet was actually sent.

But maybe Twitter or some other app can start including that location (Brightkite is already location-based, and works with Twitter), and then we can get real-time information from where we actually are on an AR screen like this. There's still a few obstacles, but once those are evened out, the possibilities are very exciting.

Shazam is an app that's been on my iPhone since the beginning, and in fact, everyone should have it. Besides the fact that it's free, it's useful in a very innovative way: if you hear a song anywhere that you don't know the artist or name of, just pull up the app to hear it, and it'll tell you what you're listening to. I still use it occasionally to find new music that I hear and like out in the world, but I never really paid attention to updates -- they usually just got included in my monthly or so "download all updates" click. Apparently Shazam's been updating something fierce, however, and the newest version has all kinds of functionality that you might not expect.

At some point, they added in Twitter integration, so if there's a tune you want to share that way, you can do so. There's always been a way to share them via email, too, and they've spruced that up a bit by calling it a "postcard" (conveniently also giving your friends a chance to buy the music you hear, and probably put some change in Shazam Entertainment Ltd.'s pocket -- it is a free app, after all). But the most interesting new feature is that Shazam now tracks your location when you "tag" a tune, so that eventually, you'll be able to look at a map of where you found all this new music you like.

Sure, it wasn't exactly a pressing feature, but it is cool to see your "musical journey," and have that information about not only what you tagged but where you tagged it. Shazam is an app that's probably on your iPhone already, but it's worth another look.

If you own a GPS system, then you're sure to know about the best feature ever invented for GPS: The "Take Me Home" button. Most GPS systems can store your home location and route you back to it with a single tap. The iPhone, of course, doesn't have one of these features ... until now.

Get Home [iTunes link] gives you many options for finding your way back home. You can add a button to the main screen of the app that will call a taxi, find your current location, call a contact, text message a contact, get walking directions, or find a bus route. At the bottom of the app's main screen, you will find how far away you are from your home location. From this same screen, you can tap any of the buttons you've added to open the Maps app and perform the requested action; for instance getting walking directions. If you select to phone a person or text a person, those actions will be carried out immediately as well.

Get Home is a good application for people who like to do a specific task from one application. The main purpose of this application, which is to find a way home, can be carried out mainly with the Maps application and saving bookmarks. That being said, Get Home does work as advertised and does have a nice interface. You can purchase Get Home from the App Store for $1.99 US.

The most recent update of iPhoto to version 8.0.2 included a couple of new features around the Faces functionality for identifying people in photos. Apple, however, was kind enough to throw in another feature; one which I was hoping would show up from the day iPhoto '09 was announced.

It is now possible to copy geodata from one photo and paste it into another photo. While this feature might sound useless at first glance, the reality is that it can be very applicable. Consider this: you have a tried-and-true digital camera that you've had for years. Along comes iPhoto '09 and it's fancy-schmancy geotagging chops make you feel old and outdated. Well, fear not dear friends, your trusty iPhone 3G has GPS built right in.

The process goes like this: wherever you are out taking pictures, snap an additional photo using your iPhone 3G then copy the geodata from the iPhone picture to all of your other pictures taken at the same locale. This process will work with any photo that has location information, not just an iPhone 3G's photos.

To do this, select the photo with the geotag information that you took with your iPhone 3G. Right-click (or command-click) the photo and choose "Copy." Next, select the photo(s) that are missing said geotag information and right-/command-click the photos then choose "Paste Location."

Now, you too can take part in all of the GPS-y goodness of those new-fangled cameras without having to buy any new gear.

My current city of Chicago isn't really suffering for Apple Stores -- the one on Michigan Avenue kind of makes up for any other missed areas around here, as it's the nicest and biggest one I've seen (but then again, I haven't been to the ones in New York near Mr. Rose). But it's good to hear that we're going to be getting another store, this one a little bit outside the Loop, on the city's northside. State Street and the theater area, you might think, would be a little more fitting for the next big retail center, but no: apparently the burgeoning retail area between a gutted Cabrini Green and Lincoln Park is the place to be. Coincidentally, I used to work as a manager at the North Halsted Borders there -- served cafe sandwiches to John Malkovitch and found a book for Kurtwood "Clarence Boddicker" Smith, both visiting from Steppenwolf down the street.

But perhaps I'm getting too personal -- just color me excited to have a new Apple Store even closer to where I live now (near Clark and Diversey). The new store is set to open on the empty lot that used to be taken up by a gas station between North and Clybourn (right across from the Red Line stop) and would have about 15,000 square feet in the "long-term location." No word from Crain's yet, though, over when the store would open or even when ground might be broken. Still, all of the development guys seem happy -- they'll probably get in there as fast as they can.

AppleInsider claims that Snow Leopard will include developer hooks that will determine a Mac's geographical location and provide additional multi-touch support for Mac laptops with glass trackpads.

While Macs don't typically come with GPS built-in, the location determination feature will work similarly to the original iPhone and iPod touch: Using triangulation between several known WiFi locations, a technique introduced by a company called Skyhook. There are tools you can purchase to take advantage of Skyhook positioning today, but Snow Leopard will give developers the option of including them in any application.

Similarly, Cory mentioned some time ago that betas of Firefox 3 already take advantage of multi-touch gestures. AppleInsider's source claims the framework has been planned for inclusion since June.

The two sets of developer hooks will bring Mac OS X closer to its sibling platform, the iPhone. MacDailyNews claims it's a union that will produce a "MacBook touch," for which prototypes they claim exist today.

Craigslist is one of my absolute favorite sites on the 'net -- it's been around for years, but kept the same simple look and feel, perfectly fulfilling the service of classifieds without ever once going off that course. Sure, there are issues with spam, but Craig and his minions have worked overtime to make the thing work, and it works well (in fact, if you see any weightlifing dumbells for sale in Chicago, let me know, I need some).

There are quite a few iPhone apps featuring Craig and his list out there (including a few with prices on them), but one that caught our eye as a useful free app is Craigsphone, made by Next Mobile Web (they make the very useful Dial Zero app as well). As you can see from the video above, it's all the features of Craigslist made mobile, and then some -- you can see your history, post and call directly from the phone, and even use the iPhone's location to see craigslist entries nearby (though unfortunately, the Nearby features only work in San Fransisco and Manhattan -- no Chicago?). NMW claims they're still working on the app, too -- they want to "take the best local site in the world and make it truly local." Who knows what that means, but it sounds good, right?

If you spend lot of time on Craiglist, or just want to while you're out and about, Craigsphone seems like a good way to do it. We're interested to see what else they've got planned, too.

I should say, even before I start this post, that I've moved my iTunes library from one installation of iTunes to another, and what I did was just copy everything in the /Music/iTunes folder from one Mac to the other. But that's the transfer equivalent of parallel parking a semi and stopping when it "feels right" -- it worked for me, but I wouldn't recommend it for anyone else. I also have almost no iTunes purchased music in my library, and that's likely not the case for anyone else.

Fortunately, for people who don't enjoy playing Russian Roulette with their iTunes library transfers (and don't want to buy the software for it), here's a quick and easy guide to how to transfer everything over properly, and make sure that all the little hooks and crannies line up correctly in the new installation -- specifically, iTunes keeps an XML file that tracks where everything is, and you've got to change paths (using a quick find and replace) on all the tracks in your library. iTunes will then use that XML file to backup its own records, and then you're hunky dory.

What I can't find, according to this guide, is what damage I may have caused to my system by just hauling everything in and starting up iTunes -- I checked the Location key on both my new Mac and the old one, and the Locations are completely different, without me ever changing them. Either way, even though I throw around my libraries with abandon (look Ma, no backup!), you'd probably much rather be safe than sorry.

Thanks, Robert!

If the iPhone has done anything, it's brought prominence to location-based computing. Where you compute has become as important as what you compute. A few months back, I helped out a TUAW reader by building a location application called Findme. It automatically fed the iPhone's location to Twitter, providing an emergency fallback in case the iPhone was lost or stolen.

How people started using Findme really took me by surprise. Read on to find out why.

NetworkLocation is a handy utility that allows you to create templates of actions and settings based on (you guessed it) your network location. Like WiLMa and Location X before it, NetworkLocation can set up batches of settings to apply, apps to open and scripts to run, and keep them all accessible at the click of a mouse. It comes with preset actions, such as loading a specific iTunes playlist, setting system volume and connecting to a server, but it can also run AppleScripts, leaving the possibilities wide open. NetworkLocation does all this with a very slick and flashy UI; in fact, it might be too over-the-top for those who just want to get at the meat of automating their system. In fact, the UI is so glammed up that John Gruber had a hard time figuring out how to quit the app. Here's a tip if you're in the same boat, as there are two ways to do it: click on its menubar item, then click on the timer in the window that pops up, and then click the power button that slides out. You can also simply use cmd-q when that timer window comes in to focus. See what I mean about a funky UI?

Getting back to this concept of automating all forms of system settings - it's a great one, and I was first turned on to it by Location X (recently Universal-ized), which is still my favorite primarily because it handles all these tasks automatically in the background, based on which network(s) you connect to. There's no need to pop up a window and chose a location - you simply set up your batches of settings, and it gracefully performs your tasks automatically as you move between your home, work and favorite coffee shop's network.

But I digress (again) - this is a post about NetworkLocation, as it looks like a capable (though flashy) approach to network-based Mac automation. A demo is available, and a license costs $15.

WiLMa is a utility for adjusting various settings like Mail servers, default printers and even desktop wallpaper based on which Location you're using (check your Apple menu if you're unfamiliar with the Location menu). WiLMa can even open and close applications and set a default network to join. If you're a nomad who bounces from places like work, school, home and who knows where else, this could be quite a handy utility, though it isn't without at least one disadvantage: it runs as an application, which means you need to have it in your dock if its corresponding menubar item will be accessible. Location X, by comparison, is more of a daemon that runs in the background, watching which Location you're using and automatically adjusting these settings to your preferences, without the need for an app to run in the dock.

Of course, with WiLMa's more attractive $12 price tag (Location X is $20), Universal Binary status and unique features, WiLMa definitely has a good thing going for it. A demo is available from Codehackers.

Location Switch is an Automator action that adds some painfully missing features to Mac OS X's built-in Locations option (y'know, that feature you never touch in the Apple menu?). Location Switch can a whole host of application preferences and settings based on which location you chose, such as sound volume, SMTP servers, default printer, etc. Before you use it, however, the action requires some customization on your part, so check out the accompanying ReadMe file for instructions, and open the action in Automator to give it your personal touch.

Location Switch is available free from Automator World, but if you enjoy it, consider sending its creator, Charles Schoenfeld, a donation at his site.

Location based social-networking is a concept that has been bouncing around the net for a while now. The idea is to make getting together and interacting with people easier by sorting users by--or simply displaying--their geographic proximity to you. Services such as dodgeball have become hugely successful in mobile markets, and Meetro is attempting to do the same thing for desktops and laptops. With Meetro, you create a buddy list, and are alerted whenever someone on that list comes within a user specified distance of your current location. I'd get into the magic internet voodoo that Meetro uses to figure out where you are, but their FAQ page is currently down.

Although Meetro is the first location-aware instant messaging service that I know of, I can't see it taking off. My issues with it are two fold; I have to create a whole new identity to use the service, and if I want to know where my friends are, I have to get them to do the same. Although the interface of the program has come a long way from when I first saw it in its early beta stages, its still not nearly as user friendly or intuitive as I would like. Ideally, I'd like to see a plug-in for iChat or Adium which allows me to see the location of my regular AIM/MSNIM/YIM buddies when I mouse over them.

In any case, Meetro is certainly an interesting concept, and worth checking out, even if only to get a taste of what surely will be many similar services to come.

Here's an easy tip for quickly opening the Finder location of a file you currently have open in almost any app.

Let say, for example, that you're working in Photoshop on an image that's buried a few folders deep within your Home folder. You'd like to get to that file's location, but unless you've used Dave Caolo's tip for taking control of your sidebar (or you have another trick up your sleeve), it requires clicking on the Finder icon in the dock, then digging deep into the folder system. Well to bypass all that clicking, all you have to do is command click on the small icon at the top of the image window in Photoshop to open a popup list (pictured) of the full directory structure leading to your file. As you can see, my hard drive is named Stewie (yes, I use Family Guy character names for my drives), and my Home folder is named dcharti. I could then click on any of the folders in that list to immediately open it in the Finder, making it a lot easier to boogie around in the file system.

The beauty of this trick is that it *should* work in any OS X app that has a file icon (like Photoshop) in the window's title bar (not the white menu bar which sits at the very top of OS X's desktop), and even in some apps that don't necessarily display that icon. Try it in Word and Illustrator. Then try command clicking on Safari's title bar, as it will give you a list of URLs the frontmost tab has visited (like a tab-specific history). You can even open something like a local PDF file in Safari and it will give you the directory list.

I bet this works in all sorts of other apps I haven't even tried yet, but it doesn't seem to work in database-driven apps like Mail.app and NetNewsWire. If you find some handy extras with this trick, feel free to add them to the pile in the comments.

If you're an iBook/PowerBook user who is constantly fiddling with various settings depending on where you are, point your mouse towards Location X for the solution to all your preference-changing woes. I only played with this for about 5 minutes before plunking down my $20 for it, as I am already in love. This app makes me cry out "why doesn't OS X do this already??" Then I realize I'm alone in my apartment right now, which just makes me feel weird.

Anyway, Location X is essentially a management app for all the various settings you might have to constantly set and reset, depending on which networks your Mac connects to throughout the day. For example: in between classes, I use wifi at Starbucks since all of the networks on my campus have most of their ports restricted. Well, Starbucks' wifi treats SMTP servers that require authentication in an odd way, so I'm constantly having to change my SMTP server when I sit down for a cup o' joe. But Location X, as you can see in my screenshot, can do so much more. Not only can this latest v2.5 do automatic network detection, it can set default printers, adjust energy settings, change browser homepages, run applescripts, change security preferences and so much more. It even has a plugin architecture, opening the doors for anyone else to build in even more settings and functionality.

I highly recommend this app for any of you mobile warriors out there who are tired of constantly adjusting settings like these, simply because you're on the go during the day. Location X is shareware which costs $20 (a bargain, if you ask me), while a demo that allows for 8 location switches is available here.
