    If that is your first time as a public speaker you did great! I used to have to do this in front of hundreds of people about once a month. God I would get so nervous!

    Hey Cory,
    I was trying to follow along with your presentation and get the openCV stuff working. Thank you for the excellent instructions in your repo, your gem was the only one I was ever able to install. I do appear to have openCV running now with your GEM however when running through the face detection example you have in your repo I get this error:


    OpenCV::CvStatusBadFlag: Unrecognized or unsupported array type

    method detect_objects in face_detect.rb at line 15
    at top level in face_detect.rb at line 15

    Have you seen something like this before, does this indicate that I don't have everything installed correctly?

    Thanks!

    Hey Mark, I don't remember seeing that particular error. Can you pastie a
    stacktrace?

    Hi Cory,
    I'd like to give you a bigger stack trace but it appears to only give me this:

    face_detect.rb:15: warning: OpenCV error code (-206) : cvGetMat (2882 in cxarray.cpp)
    face_detect.rb:15:in `detect_objects': Unrecognized or unsupported array type (OpenCV::CvStatusBadFlag)
    from face_detect.rb:15


    What I can tell you is that the application starts and shows a white box on the desktop, and the green light for the isight becomes active. However, nothing happens until I press a key. Once I do press any key I get that error.

    Is that helpful at all? Do you know how I can produce a proper stack trace for you?

    Thanks for trying to help!
