  • Mac 101: Capturing your screen

    Filed under:

    Everyone got a #2 pencil? Then we're ready for more Mac 101, tips and tricks for novices and "I forgot how to do that!" veterans alike. Today we're talking screenshots, an essential tool whenever you need to document or display something for posterity. While there are lots of third-party tools for screenshot capture, the basic functions included with Mac OS X are nothing to sneeze at.

    The original, held-over-from-Classic method for screen capture is the venerable keyboard shortcut (sometimes referred to as an 'F-key'), Command-Shift-3. Hitting this key combo creates a 'Picture 1.jpg' (or .png, .pdf or .tiff file, depending on your OS version and whether you've fiddled with your settings) that includes your entire desktop, multiple displays and all. Too much of a good thing? Try Command-Shift-4, and drag the crosshairs over the target area (hit Spacebar to toggle a 'camera' icon that will capture a full window with a click; hit Esc to get out of capture mode). As you use these keys, and a collection of 'Picture N.jpg' files begins to accumulate on your desktop, try adding the Control key to the combo -- Ctrl-Cmd-Shift-3/4 sends the captured image to the Clipboard, rather than a file. Personally, I use the clipboard version of the 4 key all the time to copy snippets of my iPhoto images into outgoing mail. It's faster & easier than exporting the full-size image.

    Sometimes, unfortunately, a command key is not quite good enough; for example, it's tricky to capture a pull-down menu onscreen. For this, there is Apple's Grab application, hiding out in your Utilities folder (also available as a Service in many applications). In addition to basic capture acrobatics, Grab offers a Timed Capture tool that works exactly like the timer button on a camera: hit the Capture menu/Timed Screen (or Command-Shift-Z), start the timer, get your ducks in a row and wait ten seconds. You can even Cmd-Shift-4 the resulting full-screen image to snag a small section if that's what you need. Happy snapping!

  • ssh on iPhone

    Filed under: , ,

    Over at the #iphone channel at irc.osx86.hu, the thoroughly awesome NerveGas has figured out how to enable ssh on the iPhone without using restore mode. The secret lies in overwriting an existing binary and plist to trick the iPhone into calling chmod on the Dropbear ssh server and making it executable.

    At this time, NerveGas has used Nightwatch's compiler to create iPhone-compatible versions of curl and ps as well as a number of other useful Unix utilities. (He's working on grep, as I write).

    So what does this mean? Well, once you've got ssh installed on your iPhone and active, you can access your iPhone from a shell on your Mac. You can send and retrieve files using scp or sftp. And you can use the compilation toolchain to build other Unix utils or even your own software. It's just a short matter of time until perl and other command-line utilities are iPhone-ready.

    Thanks to NerveGas and also to pen-x for figuring out how to get Dropbear working and Nightwatch who got the entire compilation toolchain working, to iZsh, and to BabyJesus.

  • Faster printing through Quicksilver or a simple drag and drop

    Filed under: , ,



    At TUAW HQ we absolutely love Quicksilver, the powerful, incredibly extensible and indispensable productivity tool, as it's capable of speeding up just about any conceivable operation on your Mac. Still, with everything Quicksilver is capable of, I honestly never thought it could be used to help you print documents faster. Sure enough, I have been taught my lesson to never doubt Quicksilver's reach by Mark Fisher, author of this Faster Printing with Quicksilver. In summary, Fisher's how-to walks you through adding your printer to Quicksilver's catalog so it can be used as a target for sending files to print. Combined with the Quicksilver comma trick, you can send multiple files to your printer at once, all from the streamlined efficiency of Quicksilver's search interface.

    One downside to Fisher's tip, however, is that it requires a bit of digging around in Quicksilver, not to mention a decent workout training oneself through the app's arguably steep learning curve. If all this tinkering simply isn't your bag, there's a much easier trick I wrote about last year for creating a drag-and-drop desktop printer. This is much easier for virtually anyone to set up for themselves, and as a commenter on that post mentioned, you can drag that desktop printer to the right side of your Dock and delete the Desktop icon altogether, saving precious space for... well, probably all those documents you need to print off to begin with.

    Ultimately, either of these tips are a great way print your documents more efficiently, as they remove the need to open each individual app and print the documents manually, one by one.

  • FlickIM: A nice AIM solution for iPhone

    Filed under: ,

    Until Apple releases "iChat Mobile," developers will compete to produce the IM solution for the iPhone. So far, we've considered JiveTalk and Meebo. The former was definitely better than the latter, but neither was perfect. Today, we're looking at FlickIM.

    FlickIM supports AIM only, which is a drawback (JiveTalk allows simultaneous connections to AIM, MSN, Yahoo!, GoogleTalk, ICQ, and Jabber), but has the nicest UI of the three. Simple "chat balloon" icons keep tabs on multiple conversations, and your contact list is displayed as a dial selection tool.

    I did notice one oddity: After I thought I had logged out, iChat on my Mac complained that I was logged in at two locations.

    Again, it's not perfect, but it's still nice.

  • Übercaster, all-in-one podcasting tool receives new features, enhancements

    Filed under: , , ,

    It's been a while since we've written about Übercaster, the all-in-one tool for recording, editing and publishing podcasts, but that doesn't mean its developer, Eberhard Rensch, hasn't been hard at work on it. Through updates over the last couple of months, Übercaster v1.1.5 has gained a ton of handy new features and polish, such as:
    • Delete and Close Gap: Instantly re-join two pieces of a track after cutting out a portion of the middle. A big time saver when editing out the false starts and other mistakes.
    • Reset Playhead on Stop: An option to automatically return the playhead to its original starting point. Another huge timesaver when reviewing a specific clip.
    • Split All Tracks: Splits every track at the playhead, regardless of which tracks are selection.
    • New PleasantConnect version: An update to the Mac OS X kernel extension included with Übercaster that allows for pulling off tricks like recording Skype conversations in separate tracks, with you on one and any caller(s) on another.
    • New progress bar in Dock icon: This is great for a real-time yet unobtrusive display of a podcast's upload progress.
    • Sparkle integration for automatic updates: Andy Matuschak's popular Sparkle framework has made to Übercaster, providing wonderful automatic software updates that so many apps are enjoying.
    This isn't all though; there are far more new features and bug fixes listed in just the last two updates than I can fit in this post, so check out the Übercaster changelog or grab the latest version yourself. If that updated kernel extension can fix my problems and allow me to record multi-track Skype conversations, Rensch will certainly be seeing a $79.95 purchase from me.

  • Shiira 2.2 updated for Safari 3 beta's WebKit

    Filed under: ,



    When Apple makes changes to WebKit - the open source rendering engine that powers Safari - like they just did with the Safari 3 beta, many, many other Mac OS X apps that have anything to do with websites need to do a little catchup so things continue to run smoothly. Shiira, the feature-packed alternative browser, is just such an app that fortunately just made the leap to Safari 3 beta compatibility. Aside from the twelve new localizations introduced in this new v2.2 update, I can't tell what else has changed. Still, if you installed the Safari 3 beta and noticed that Shiira has been misbehaving one way or another, this new version should calm the waters.

  • NYT reports on first announced iPhone vulnerability

    Filed under: ,

    Happy Monday, everyone; are you done reading Potter yet? Here's a somewhat less magical story for you. Today's New York Times includes an article with the utterly un-sensational headline "IPhone Flaw Lets Hackers Take Over, Security Firm Says" (yes, Times-style requires that even the 'i' in iPhone be capitalized in a headline), discussing the discovery of a buffer overflow exploit in Mobile Safari. The exploit, which can be triggered by browsing to a malicious page in Safari from the phone, claims to allow the execution of arbitrary code, and could expose personal information to an attacker. The exploit is not in the wild and has been reported to Apple; full details are at the Independent Security Evaluators site.

    Is this a very bad thing? Not necessarily; it's not a zero-day vulnerability, the research team is communicating with Apple, and there is no released exploit code out there in the big bad Internet that can currently zombify your iPhone. Unlike many smartphones, which may not have a frequent firmware update mechanism, the iPhone is syncing to iTunes constantly and can be updated at any point, so one would hope this gets patched rapidly. If you use some basic precautions (don't click mystery links, don' t use unfamiliar wireless access) you should be covered if something like this ever sees general distribution.

    Is this, on the other hand, an top-notch opportunity for some iPhone and Mac OS X security FUD from the Grey Lady? You betcha. Let's take a look at some of the assertions in the article, and compare them with both the claims of the vulnerability discoverers and the reality on the ground.
