I just updated the OpenCV on iOS Xcode project to use the git repo as a submodule for OpenCV.  I've also fixed the SURF demo.  Take a look!

(The git mirror that I had created for OpenCV's svn is now gone.)

Note: If you've cloned a previous version, use git submodule init and git submodule update after pulling the latest rev to pull the correct version of OpenCV. If you get build errors, you probably need to do this.

Check this out. Instead of several steps, some ugly CMake voodoo, and some work in the shell, now all you have to do is pull down a git repo to make OpenCV work on iOS. A couple of people have tried it out and found it functional. Let me know at "my first name at this domain dot calm" whether it works for you. If anyone would like to use the example project to make instructions on how to make it work in a new project or even generate some project templates, get in touch or give it a go and submit a pull request on github.

When the news came out today that Apple has chosen to lift the iPhone NDA, I (like many developers) breathed a sigh of relief. I would like to take a moment to thank my peers for being so outspoken and to thank Apple for finally deciding to make my life as an iPhone developer excedingly easier by allowing the members of the development community to do as they so often and so unselfishly do to help one another with various recurring difficulties that crop up in our craft. The Mac OS X software community that I've had the pleasure of getting to know over the last couple of years continues to astound me. I'm proud to count myself among them. They are, to a person, a wonderful, well-meaning, honest, and interesting group of people who, as evidenced by the recent brouhaha over the aforementioned NDA, are very vocal about their beliefs and try to treat others as they expect to be treated. I've decided to take a page from that book and voice a belief of mine: A contract is a contract.

Having had the pleasure of arguing over contracts (including several of my own), intellectual property, personal liberty, and many similar topics with more than a few software developers, attorneys, students, musicians, my astonishingly intelligent parents, and various other people I have admired over the years, I've come to a few conclusions. One of the fundamental principals I try to follow in my own dealings with others is, I'm told, a basic brocard of civil law -- Pacta sunt servanda ("agreements must be kept").

I just found out that one of my idols Max Roach has died. Say "M-Boom" to Vonnegut for me!

Having been a MarsEdit user since before its Red-Sweater-ization, of course I just bought me an upgrade for that there brand spankin' new MarsEdit 2.0. It's awesome, as expected.

Daniel Rocks.

Carry on, punkass.

Do you:

Hang out with nerds?
Make sound with something you have to plug into a wall?
Like bars that have LCD screens embedded in the furniture?

Then come out to Bar Mundial on Sunday at 9 PM to experience the
premiere performance of Jonathan and Amelia's Robot Laptop Band!

We'll be performing a featured set at SHARE (http://share.dj), which is a weekly
audio/visual laptop jam in the East Village. We'll be showing off the
bugs in our current "work in progress," and making troublesome noise
and visuals to open the evening's jam session this Sunday, February
12, 2004.

You'll be sure to find us drinking and joining the jam session after
the set. If you make noise or video, bring your axe and plug in. A
projector, a mixer, and amplification are provided; BYOC (Bring your
own cable). It's really fun and informal and nobody minds if your
computer crashes, if your Max patch explodes, or if your delay pedal
goes haywire. In fact, most of us like it when that happens.

No cover!

About us:

We're a couple of self-professed computer nerds / artists who make
noise and images with computers. Using technologies like OpenGL,
superCollider, C++, Python, Open Sound Control and The Macallan Single
Malt Highland Scotch Whisky, we create interactive real-time audio /
visual performances.

I somewhat impulsively deleted my myspace.com profile a couple of days ago in an effort to prod myself into putting some "real" blog software on my new server/media center/mac mini/ does-everything-except-make-toast (so far) computer. So here it is, folks! I'll be archiving some of the old posts from myspace here and generally using this space to let google index my brain, so-to-speak. If you're somebody I know "in real life" or if you just want to say "HI," drop me a line here.
