  • …here goes nothing. Mobile Logger submitted.

    Just submitted MobileLogger to the AppStore. Hoping this goes smoothly given my tight schedule for thesis. For reference, when there are multiple versions of Xcode / iPhone SDK, specifically a beta version alongside the release version, and using xcodebuild command…explicitly set the xcode path to the release version or the application may be built against […]

  • OCR for iPhone source

    The source code for the Tesseract OCR for iPhone project has been published. It’s really simple – more of a skeleton, proof-of-concept project than anything else. Still, though, it’s neat to have nearly point-and-shoot text conversion in your pocket. The project page is: Pocket OCR The source code is available at github: http://github.com/rcarlsen/Pocket-OCR There is […]

  • PinwheelBeta – adhoc

    In preparation of submitting Pinwheel to the App Store I’ve gone and released a beta version via ad hoc distribution. Seems like it should be a straightforward prospect, however the various device provisioning, code signing profiles and entitlements made it a bit of a process for a first-timer. iTunes also seems to be entirely unhelpful […]

  • …little help (oh, malloc)?

    i’m having a time of it tracking down a resource allocation bloat culprit in an iPhone app i’m working on. i’ve narrowed it down to when i’m rapidly updating the center property of a UIImageView. a snippet from the Instruments application is below: there are hundreds (if not thousands) of these messages, and the object […]

  • Using openFrameworks for iPhone dev

    [Also available at ITPedia. Watch video of the BarCampNYC4 presentation.] This is an overview of getting set up using openFrameworks for iPhone development. What is openFrameworks? openFrameworks is a “a C++ library for creative coding”. It shares a similar philosophy with Processing (as a library for Java). The intended audience “are folks using computers for creative, artistic […]

  • counting change

    As an in-class exercise for Spatial Media we were asked to develop a program which would identify coins in a series of supplied images and tally up their total value. In one hour. Since time was limited, I decided to use pixel count as a rough estimate of each coin’s size. This works very reliably […]

  • openFrameworks + iPhone libs

    I’ve had a few days to test the libraries I cobbled together for using openFrameworks with iPhone and also received positive reports from some folks who tried out the Makefiles I provided to them, so here they are for anyone who’s willing to try them out. -please make these instructions better if you see fit-

  • Using Arduino in Xcode

    While the Arduino IDE (Integrated Development Environment) is relatively simple way to program the Arduino hardware, I found myself getting frustrated by it’s limited features after spending time using Xcode and Eclipse. There are some simple tutorials available online which demonstrate how to set up Xcode for programming the Arduino, however these didn’t “just work” […]

  • my first iphone app :)

    (i was going for a fisher-price approach with the title…) regardless, i’ve finally gotten around to iPhone development. my developer account was approved last week, and apple happily took my $99 in exchange for slightly greater access to their website and an application code signing certificate. in preparation, i’ve been reading the requisite docs on […]

  • qmake / xcode bug

    super annoying…Qt advertises that you can make an xcode project file using qmake to enable native development on mac…i had never been able to get the golden cheetah project working in this way, even after following what little documentation i could find. each time i’d run “qmake -spec macx-xcode” would result in a non-parseable xcodeproj […]
