Video Introduction to Cocoa

Posted May 23rd 2008 5:00PM by Mat Lu
Filed under: Video, Developer, Found Footage


Over at Theocacao Scott Stevenson has posted the video of his Introduction to Cocoa talk (entitled "Best of Both Worlds") aimed at those who want to learn a bit about Apple's preferred API for building OS X applications. The talk runs to over 90 minutes and includes "an introduction to Xcode, Interface Builder, Objective-C, Mac UI standards and more."

For anyone who has ever wanted to figure out what those developers tools are all about this is definitely worth (the rather large) download (scroll down towards the bottom) though it seems that a lot of folks are have problems getting the whole file (myself included). There's also a torrent available.

Flickr Find: Twitter in Mac OS X developer tools

Posted May 6th 2008 8:30PM by Cory Bohon
Filed under: Flickr Find


An avid reader of TUAW, Chris Thomson, sent us a link to a Flickr picture (being the nosy people we are, we clicked the link). What we found surprised us -- a Twitter Quartz Composer composition was included as a part of the Mac OS X developer tools for Leopard. "Twitterverse," when tweaked right, can be used as an OS X screen saver and display all of your friends tweets in a graphical way.

You can find this Quartz composition in the ~/Developer/Examples/Quartz Composer/Compositions/XML/The Twitterverse/The Twitterverse.qtz. If you want to add it as a screen saver, just drag it onto the preview in the "Screen Saver" part of the Desktop & Screen Saver preference pane (in System Preferences.app). You can then add your username / password in the screen saver options.


Thanks, Chris!

Xray your code with new dev tool

Posted Jun 12th 2007 11:00AM by Mike Schramm
Filed under: WWDC, Leopard, Developer


A few tipsters have dropped us notes (thanks!) that on Apple's Developer Tools page, there's a new tool. Along with Xcode and Dashcode, there's a new, very pretty app called Xray. The flavor text itself says the app takes "interface cues from timeline editors such as GarageBand," so what we're looking at here seems to be a realtime application tester and analyzer.

The three windows in the screenshot show stats on "Network Traffic," "CPU Load," and "Reads/Writes," and Apple also says devs will be able to track user events and even the OpenGL video driver. Looks like it will bring all the new tracking tools and analysis junk (technical term) together in a browsable, graphical interface, which means an easier time for devs, which means better apps for all of us. Groovy!

Neat iSight trick - Seeing you, seeing me

Posted Nov 14th 2006 11:30AM by Laurie A. Duncan

Caught this on MacInTouch and I'm still a little freaked out by it. If you have an iSight camera, check out this neat trick.

It's not magic, really, it's just a QuickTime movie embedded in a web page, but the fact that it displays YOUR iSight, even though it's not your web page is a little disconcerting! As Chris says, it's pretty easy to do this yourself. Install Apple's Developer Tools if you don't already have them installed. Open Quartz Composer. Create a video input and a billboard. Then drag a line from the video input to the image option on the billboard. Now export it as a QuickTime movie and embed it into your web page.

No need to fear it, however. No one else can see you. Everyone who views the page will only see themselves (assuming they have an iSight). I think it's still a pretty cool trick, however, you are free to disagree.
