TUAW TV Live at 5 PM EDT: Catching the TUAWloha spirit
Just when you thought it was safe to go back to your computer, two of the most recognizable voices in Mac-dom are back. My mellifluous voice and that of the pride of the Aloha State -- Doc Rock -- will be gracing the Interwebs today in our special pre-Fourth of July episode.
Actually, there's nothing special at all about today's episode, but it's always a lot of fun when the Doc does a house call. I've got a few new products to demo, Doc and I will be talking about a fun new app that keeps your calendar within view at all times, and we'll generally make the one-hour show go by very quickly.
As usual, I'll be starting the show at 5 PM EDT (2 PM PDT / 10 PM BST) sharp, and we'll take a few minutes to chat before the fun starts. To join in on the chat and watch the live streaming video, drop by TUAW about five minutes before the start time to get your instructions on how to participate. If you're unable to join us for the show, remember that you can always subscribe to the video podcast and watch the show at your leisure in iTunes or any other favorite podcatching app. The past shows are also available on the TUAW YouTube channel.

Analyst: the cheap iPhone will be a free 3GS
Analysts really want Apple to enter the low-price smartphone market. So much so, they can't stop talking about this rumored cheap model. The latest analyst to chime in on this topic is Mike Abramsky of RBC Capital. He predicts Apple will release a cheap iPhone model when the iPhone 5 debuts. It won't be a new model, though. Instead, he expects the iPhone 3GS to be offered for free. Apple will also drop the price on the iPhone 4 to US$99, says Abramsky.
Earlier this week, Deutsche Bank analyst Chris Whitmore kicked off this rumor again when he proposed the idea of a mid-range iPhone 4S that will launch along with the iPhone 5. Toni Sacconaghi of Sanford Bernstein also called for Apple to release a lower priced iPhone, but did not mention an iPhone 4S. Keith Bachman of BMO threw a monkey wrench into everyone's predictions by dismissing the idea of a cheap iPhone and predicting a single, full-featured model - the iPhone 4S.

How to Back Up Your Computer
You never think losing your files will happen to you until it actually does, and you're caught without a backup. Backups are extremely easy to keep, so there's no reason not to have one. Here's how to set one up.
Whether you accidentally delete a file or lose a bunch of your data to a hard drive crash, regularly backing up your machine is always a good idea. Both Windows and Mac OS X have great built-in backup utilities, so it only takes a few steps to get started. Here's what you need to do.
On Windows
- Get a backup drive. This can be just about any USB external hard drive, and you can get them at most electronics stores. Try to get one that has twice as much space as your computer, so you have room for multiple backups and so you have room for all the data you might get in the future.
- When you first plug it in, Windows will actually ask you if you want to use it as a backup. Tell it that you do. If you don't get this prompt, you can just go to the Start Menu, type "backup" in the search box, and hit Backup and Restore.
- From there, click the "Set Up Backup" button. Pick the external drive you plugged in and hit Next. Windows' default settings are probably fine, so you can just hit Next and the next screen too.
- On the last screen, hit "Save Settings and Run Backup". Windows will make its first backup of your drive, during which you don't want to turn off your computer. After that, it'll make regular backups in the background as you work—you don't need to deal with it again.
If you ever need to restore a file you lost, you can just go to the Start Menu, type in "backup", and go back to "Backup and Restore". You can hit the "Restore My Files" or "Restore Users Files" buttons to get those files back.
On a Mac
- Get a backup drive. This can be just about any USB external hard drive, and you can get them at most electronics stores. Try to get one that has twice as much space as your computer, so you have room for multiple backups and so you have room for all the data you might get in the future.
- When you plug in your drive, your Mac will ask you if you want to use that drive as a backup disk. Hit "Use as Backup Disk". If you don't get this prompt, you can always go to System Preferences > Time Machine to set it as a backup disk, too.
- From Time Machine's preferences, hit "Select Backup Disk" and choose your external drive.
- That's it! OS X will perform its first backup (during which you'll want to keep your computer on), and from then on it'll back up in the background with no work required on your part.
If you ever need to restore a file, just click on the Time Machine icon in your menu bar and hit "Enter Time Machine". From there, you can search through your old backups for the files you lost and restore them to your hard drive.
There is, of course, one downside to this method. While it'll save you if you accidentally delete a file or have hard drive issues, it won't save you if, say, you have a fire. For truly bulletproof backup, you'll want to back up all your data online, so you can get it back wherever you are (and whatever happens to your hardware).

Spain Increases English Lessons to Decrease Unemployment
Spain currently has an unemployment rate of about 20%, which is twice as high as the European average. According to the New York Times, more and more Spaniards are searching for employment opportunities abroad. Unfortunately, many are experiencing difficulties due to poor foreign language skills, specifically their lack of knowledge of basic English. Many adults are returning to school to learn or improve their English or another foreign language.
While the current job seekers are having a hard time because of language barriers outside of Spain, education reforms are being made to ensure that future generations will not encounter such troubles. A third of Madrid’s primary schools are bilingual, and by 2015 they are hoping at least half of the schools will be teaching more languages. In addition, more and more schools have begun employing English speaking teachers.
Spain has a long way to go because in addition to struggling with vocabulary and pronunciation, even the campaign has poor grammar. The campaign to promote bilingual education boasts the slogan “Yes, we want!”. Richard Vaughan, owner of Vaughn Systems, an English teaching company, estimates that less than five percent of graduates of engineering, law or business have even a working knowledge of English.

TUAW's Daily Mac App: swackett
Most weather apps display weather as you might expect with temperature and weather symbols. Swackett, a free (ad-supported) weather app from the Mac App Store, bucks the trend with cute cartoons of people showing the current and forecasted conditions.
A "different kind of weather app," swackett shows you your current local weather conditions as well as today's, tonight's and tomorrow's forecast using characters of people wearing "suitable clothing" for each condition. For instance, if it's cool but not cold, swackett shows people wearing a light jacket, jeans and T-shirt. If it's going to rain, you'll see someone holding an umbrella. You'll even come across "easter eggs" for certain weather conditions from time to time, such as characters replicating a scene from Gone with the Wind for hot and sunny weather. A break-down of the day's weather is also displayed in 2-hour intervals along with a 7-day outlook and local, regional and national radar, plus regional satellite maps.
Weather information is powered by AccuWeather.com, so there's a good chance your location is available. You can even tweet the current weather condition directly from the app.
Swackett is also currently available as a web app (iPhone app coming soon), so you can get your weather predictions in the browser, too. An optional free login lets you save location and preference settings for temperature and other customizable features across devices. If you get sick of the free swackett characters, more can be purchased from the swackett store with "British Invasion" and "The 1950's" available for US$1.29 each.
If you're looking for something a little different from a standard weather app that'll make you chuckle, then download swackett for free from the Mac App Store.
