NSSpeechSynthesizer, the Cocoa class responsible for giving applications a voice under OS X, is leaky. Creating and destroying thousands of instances of this class slowly consumes all the available memory in a system, leading to degrading performance and eventual application instability.

The disappointing part is that this bug was first noticed almost two years ago. (more…)

The Kineme Quartz Composer patches now have a proper home at http://kineme.net/, including forums, bug reports, comments, and feature requests — complete with voting!

Along with the new site, a few new patches are available as well based on requests from users.

While writing the new Image Downloader (Blocking) QC patch for CoreMelt, I ran into what appears to be a bug in Mac OS X’s NSURLConnection framework — if you construct an NSURLRequest and specify a timeout of less than 30 seconds, it’s ignored when you perform a [NSURLConnection sendSynchronousRequest:returningResponse:error:]. The request takes at least 30 seconds to time out, contrary to what the documentation suggests..

Faced with a need to recover images from Robert’s camera after a defective card-reader nuked the filesystem superblock, a quick utility came to mind. Nuked superblocks mean no file allocation table. It means no metadata. But it does not mean no data.

• Target medium: 1GB XD card from a digital camera.
• Data to recover: JPEGs. Lots of them.

Whipping out some jpeg-format-and-filesystem-jutsu, here’s the solution (for less than that $20 shareware recovery utility):

Making pop-up menus in custom Quartz Composer patches is actually surprisingly easy.

This release is only compatible with Tiger (10.4).
Please see kineme.net for Leopard-specific informations.

1. Set up a QCIndexPort input. QCIndexPorts provide values from 0 to whatever max you specify using - (void)setMaxIndexValue:(unsigned int)max;.

Here’s a new version of the Xcode Template for Custom Quartz Composer Patches.

Changes:

• Rebuilt from scratch — no longer depends on QCJP’s work — and, by extension, the Creative Commons “Attribution-NonCommercial-ShareAlike” license. My Xcode Template, as of version 0.2, is released into the Public Domain. You are free to use it for whatever — commercial or non-commercial.
• QCJP’s headers were replaced with headers assembled directly from the QuartzComposer framework — now located in the QuartzComposer/ folder of the project. I’ve exported a few more headers than QCJP had constructed, so there’s some added functionality (namely, image input/output ports).
• The project now automatically assigns an icon to the patch bundle, and installs it in /Library/Graphics/Patches/ for you each time you build, for faster edit-build-test workflow.

This release is out-of-date.
Please see the latest version.

Download the installer, version 0.2.

See the old version’s blogpost for some additional instructions and user comments.
