R.I.P Toxic Progress Indicator

October 30th, 2007 · 2 Comments · Default

Thanks to Matt Gemmell for pointing out that Apple has finally provided a pie chart style NSProgressIndicator for the circular/determinate modes. This style is new to Leopard. This means my Toxic Progress Indicator class can be retired, at least for 10.5+ only applications. Leopard has really helped to retire a lot of my code (for [...]

SpaceNavigator controlled Lego Mindstorms NXT

September 26th, 2007 · 2 Comments · Default

It’s my second year of coaching a First Lego League team. The experience has been fantastic, I’m teaching 4th and 5th grade children about robots and computers, and teaching them to build and program their own robots. This year the kids are going to be learning how to use the new Lego Mindstorms NXT robot; [...]

The Intersection of Cool and Awesome

September 25th, 2007 · 12 Comments · Default

3Dconnexion (a division of Logitech) produces the coolest named device ever: The 3Dconnexion SpaceNavigator . This is a 3D input device with 6 degrees of freedom, meaning you can move and rotate it through the X, Y and Z planes. I bought it originally on a whim (hey only 50 bucks!) for use with Google Sketchup [...]

Subversion Moved

August 4th, 2007 · Comments Off · Default

I’ve had a lot of emails asking where the subversion repository has gone.

The simple answer is I’ve stopped hosting my public subversion repository on DreamHost and have now created a Google Project for it. The project URL is:

http://code.google.com/p/toxic-public/

And the subversion root is here:

http://toxic-public.googlecode.com//

Google will be a lot more reliable than DreamHost ever will be. I [...]

‘Discrete’ NSLevelIndicatorCell too slow

June 24th, 2006 · 6 Comments · Default

I recently needed to embed the ‘Discrete’ variant of the NSLevelIndicatorCell into an NSTableView. The discrete cell looks like this:

Unfortunately adding the cell caused drawing of the table’s window to slow to crawl. The spinning beachball of death would often appear when I was merely resizing the window. After some quick experimented I narrowed [...]

ToxicMedia & SequenceGrabber Stable

November 13th, 2005 · 5 Comments · Default

I’ve moved all the SequenceGrabber utility code into its own framework: ToxicMedia.framework, the code is available from trunk/Frameworks/ToxicMedia. All my projects that use CoreImage, CoreVideo or QTKit now depend on this framework. Now I don’t need to update 4 or 5 projects every time something changes.

I’ve also branched all the test projects and the framework. [...]

More SequenceGrabber Updates

October 20th, 2005 · No Comments · Default

Spurred on by interest in my Sequence Grabber source code I’ve added a whole slew of new functionality to it tonight (for various reasons this code is a lot of fun to work on). The most important change is CCoreImageView now supports Cocoa bindings and has an Interface Builder palette. This means you can easily [...]

Sequence Grabber Updated

October 13th, 2005 · No Comments · Default

My sequence grabber code (previously mentioned here) has been updated. It should be a lot easier to get up and running now - I’ve added a “CSequenceGrabberView” NSView subclasss that you just need to drag and drop into your nib’s NSWindow. I’ve also improved the error handling so that the lack of a plugged in [...]

Sequence Grabber code now has Motion Detection

August 18th, 2005 · 1 Comment · Default

I’ve added basic motion detection capabilities to Cocoa Sequence Grabber code now.

This is what happens when your cat wakes you up too darn early after peeing under the computer desk.

Sample movie (MP4/QuickTime 7 required, 64KB file): MotionDetection.mp4

No those aren’t mpeg encoding artefacts, those are my attempts to highlight the motion in the movie.
