OS X Lion ditched the longstanding “Save As” feature, something that many Mac users have become accustomed to using over the years. Replacing “Save As” are two different features, Duplicate and Export, neither of which work quite the same, and neither of which are attached to a keyboard shortcut, but we can create our own keyboard shortcut to mimmic the old behavior of “Save As” so that when you hit Command+Shift+S, a Save (Export) dialog will appear:

• Open “System Preferences” from the  Apple menu and click on “Keyboard”
• Click the “Keyboard Shortcuts” tab and then choose “Application Shortcuts” from the list
• Now click the + plus icon to add a new shortcut accessible to All Applications
• Type the Menu Title exactly as “Export…” with the three periods
• Click the “Keyboard Shortcut” box and hit Command+Shift+S
• Click “Add” and close out of preferences

Open a file in any application and try out your new “Save As” (Export As) shortcut by hitting Command+Shift+S. No it doesn’t work exactly like the old “Save As”, but neither does the Duplicate command.

This tip aims to improve on some of the suggestions that have recently picked up steam on the Apple-centric web, where some people favor macro hacks or the same shortcut but related to the “Duplicate” function instead. This certainly works, but anything tied to the “Duplicate” function requires an additional step to save a document, rather than “Export” which brings you directly to a familiar “Save As” dialog box.

Here’s another awesome tip from Keir Thomas, the author of a new book called Mac Kung Fu, which contains over 300 tips and tricks for OS X Lion. He’s the same guy who discovered the iTunes “Now Playing” notification tip and the Quick Look select text tip. Here’s the tip direct from Keir:

This is a neat little hack that lets you activate any stack within the Dock by hovering over it and making the scroll gesture on a multitouch trackpad or Magic Mouse, or by rolling the scroll wheel on a mouse.

Do the same trick while hovering the mouse cursor over an app icon in the Dock, and App Exposé will activate. You will see open program windows for that particular app and—with compatible apps—the app’s document history. This is similar to the App Exposé option within the More Gestures section of the Trackpad entry within System Preferences.

However, in each case, once you’ve activated the secret setting, you need to scroll up to activate (that is, to make the stack expand), and then scroll down to deactivate (to make the stack hide again). You’ll need to scroll a substantial amount to activate the feature so that OS X knows you’re doing it on purpose and not accidentally. In other words, you’ll need to flick the scroll wheel up rather than just rotate it a few clicks.

To activate this hidden feature, open a Terminal window and type the following:

defaults write com.apple.dock scroll-to-open -bool TRUE;killall Dock

The changes take effect immediately. To deactivate this feature, open a Terminal window and type the following:

defaults delete com.apple.dock scroll-to-open;killall Dock

If you already signed up for a few of the 10 free online Computer Science classes from Stanford University, get ready to pack your self-learning schedule even further, because three professors from Stanford University and University of California Berkeley are teaming to offer a new free online course on Computer Security, starting in February 2012.

The class is a budding hackers dream, aiming to teach you how to design secure systems and write secure code. Specific topics covered include:

• How to find vulnerabilities
• Limiting the impact of security vulnerabilities
• Memory safety vulnerabilities
• Vulnerability detection
• Sandboxing & isolation
• Web security
• Network security
• Malware detection and defense
• Mobile platform security

Even the homework and labs sound fun, you’re basically finding exploits and then patching them yourself:

Course homework and labs will teach students how to find vulnerabilities and how to fix them. The labs are designed to help students practice the principles of secure system design.

Prerequisites include concepts of computer science and operating systems, and at least some programming knowledge of C and C++.

Safari 5.1.2 has been released, and if it sounds like just another minor update to put off, it’s not, it improves overall stability and resolves some of the annoying memory management issues that existed in the prior versions of the browser. Also fixed is the flashing page issue, and a problem with displaying PDF’s within web pages.

You can update through Software Update or download Safari 5.1.2 directly from Apple.

Installing Safari 5.1.2 requires a reboot, and is available for Mac OS X Lion 10.7.2 and Snow Leopard 10.6.8.

To avoid any font face irregularities and size oddities when sending emails across platforms (from Mac OS X Mail app to Windows Outlook, for example), it can be a good idea to use the ‘Plain Text’ format for all email correspondence. Setting Mail composition to default as Plain Text in Mail.app is easy enough:

• Go to the Mail menu and choose “Preferences…”
• Click on the “Composing” tab
• Under “Composing:” click the pulldown menu next to “Message Format:” so that “Plain Text” is selected
• Close out of Mail Preferences

All new emails will be composed and sent as plain text, although making rich text modifications can still override the plain text default. To avoid this, try attaching images rather than embedding them into mail messages.

Thanks for the tip idea, Gary!

A wide variety of websites and online services are region restricted to the USA: Hulu, Netflix, Pandora, annual credit reports, some banks, the list is significant. Region restrictions are generally something you don’t notice until you need to access a website from outside the USA, and then they’re a huge pain. We’ll show you how to get around region restrictions securely by using a SOCKS proxy and SSH tunnel.

Before getting started, you’ll need:

• A US-based web hosting or shell provider that allows SSH access, including a username and the remote machines IP
• Basic understanding and comfort with the command line

This walkthrough is aimed at Mac OS X, but you should be able to configure things much the same with iOS, Android, and Windows too.

Set up an SSH Tunnel and SOCKS Proxy in Mac OS X

Assuming you have a US host squared away, let’s begin:

• Go to the Applications folder, then to Utilities, then launch the Terminal and use the following syntax to set up the SOCKS proxy:

ssh -D port_number user@remote_host_ip

• For example, if your username is AJ and the remote host IP is 75.75.75.75, and you want to setup a proxy on port 2012, the syntax would be:

ssh -D 2012 AJ@75.75.75.75

• Login as usual and maintain the shell connection for as long as you intend to use the proxy, if you’re concerned about remote host timeouts just ping localhost or another ip
• Now go to the  Apple menu and open “System Preferences”
• Click on “Network” and then click on “Advanced” in the lower right corner
• Click on the “Proxies” tab and click the checkbox next to “SOCKS Proxy” from the protocol menu
• Fill in the SOCKS Proxy server as 127.0.0.1 and provide the port from earlier, in this case 2012
• Click “OK”

Now launch a web browser and double-check the external IP address to confirm with a website like whatismyip.org or by running the following at the command line:

curl whatismyip.org

Your IP should now register as the remote US-based host you tunneling through, and you are free to view US region restricted content.

Side note: in some cases, specifically with websites that redirect based on region, you just need to find the proper URL and you don’t need to tunnel at all. A very useful example is stopping Google.com redirecting to another region by using their NCR site, but there are other search engines and websites that have similar alternate URLs.

The smartphone discussion is typically focused around iPhone and Android, but Microsoft is still cooking up it’s own unique smartphone OS: Windows Phone 7. Now thanks to an HTML5 demo, the curious can try out a basic Windows Phone 7.5 experience directly on your iPhone.

Open up Safari and throw in the following URL:

• http://aka.ms/wpdemo

If you haven’t used a Windows Phone before, the first thing you’ll notice is the similarity to the upcoming Windows 8 OS, which Microsoft says is the future of their desktop and tablet efforts (and probably smartphones too). Lots of tiles, swiping around, it’s fast and fluid and an enjoyable enough GUI. Perhaps best of all for, it’s original, as opposed to the shameless borrowing everyone else seems to have done with iOS.

Is this demo going to swing you away from an iPhone? Doubt it, but it’s always fun to see what the competition is cooking. (via Gizmodo)

Flick down with two fingers on a trackpad or Magic Mouse in Mac OS X Lion and you’ll experience inertial scrolling, where after your finger has stopped moving the page continues to scroll in the intended direction until it slowly stops. This fluid and natural scrolling experience comes from the iOS world, and while it works quite well on the desktop, it’s not for everyone.

• Open System Preferences from the  Apple menu
• Click on “Universal Access” and then click on “Mouse & Trackpad”
• Near the bottom, click on “Trackpad Options” button
• Next to the “Scrolling” checkbox, click so that “without inertia” is set then click “OK” and close out of System Preferences

Intertial scrolling is now off. Try to scroll now, and even if you flick your fingers the scrolling will end immediately when you lifted them from the trackpad, just like it’s 2005 again.

Note that in Mac OS X 10.6 Snow Leopard, intertial scrolling was called “scrolling with momentum” instead, and the option was contained within the standard Trackpad & Mouse preference panel.

iOS 5.1 beta 1 continues to spill the beans for Apple product ID’s, with the latest find being a direct reference to Apple’s next-generation iPhone, referenced as “iPhone 5,1″, and two unreleased iPad’s, referenced as “iPad3,2″ and “iPad3,3″.

iPhone5,1 would technically be the sixth generation iPhone, which may indicate iPhone 6 is the proper name for the device. Of course, nothing but speculation is known about the iPhone 5 (6?), but references appearing in current iOS 5.1 beta builds suggest there are working prototypes that are running iOS 5.1 right now in Cupertino. Most rumors suggest the next generation iPhone will have a 4″ screen, a thinner aluminum enclosure, and likely an A6 CPU, and a release time frame could be somewhere between summer and fall of 2012.

The iPhone 5,1 reference was first discovered by @Filippobiga on Twitter – you can follow us there too – who also pointed out the references to two unreleased iPad 3 models, also shown in the screenshot as iPad 3,2 and iPad 3,3. Presumably, those are for the upcoming iPad model that is expected to debut sometime in early 2012 with a retina display.

The recently released iOS 5.1 beta 1 has already uncovered a few hints about potential upcoming products from Apple. First, the Sprint iPad 2 reference, then an iPhone 5 reference, and now a codename reference to an unreleased Apple TV unit dubbed “J33″ has been found.

Other than the reference to the devices codename there is no additional information on the unreleased Apple TV device. It’s possible the device will simply be a revamped existing Apple TV model that includes an A5 CPU and the ability to export 1080p video, which 9to5mac suggests could be the case, and there is also a vague possibility it could be the rumored “real” Apple television.

Currently, the Apple TV is a set-top box that costs $99, allowing users to stream iTunes and video content directly to their TV. After the passing of the late Apple CEO Steve Jobs, there have been numerous rumors regarding a real Apple television set, said to debut sometime in 2012 or 2013. Dubbed “iTV”, the television is said to run iOS and feature Siri as the TV’s remote control, with heavy reliance on iCloud services.
