How to put a plastic adirondack chair into a honda civic

I recommend trying to put the chair into the car like this: None of the other ways seemed to work, for example: the trunk and the back door. The legs and the arms and the back... they just don't play nice with the shape of the car doors. But that configuration there... It doesn't mean the plastic chair has to hang out upside down on the front passenger seat like that... (in fact, the door won't close and the arm rest is obstructing the gear shift ) Once it's inside the car, if you recline the passenger seat and maybe the driver seat, you can twirl the chair around inside the car all you want. Then maybe you can fit two chairs! This was a very satisfying project... to not have to return these chairs "because they won't fit in my car" and to get to wrestle them home to my deck where I sat on them in balmy May-Seattle weather until about 10:30pm.

Using IPython Notebook with Django on a remote server

IPython Notebook (or Jupyter, whatver) is great. Django is useful and I use it for both work and play. The combination would be greatly useful ! My setup is something like this: I have an EC2 machine running Ubuntu, which powers a Django site. I want to be able to launch IPython Notebook on the remote server such that: It knows about Django and can import my models properly I can just write the code in a web browser on my local machine It's secure in that there's not just a stray notebook on the web that anyone can look at My mom mentioned the Django extension 'shell_plus' the other day, and that turned out to be key to this solution! Installing stuff: (I did this a few days ago and don't remember all the details, I *think* it was this simple.) IPython Notebook http://ipython.org/install.html pip install "ipython[notebook]" shell_plus via django-extensions http://django-extensions.readthedocs.org/en/latest/installation_inst

How to train your classifier (on a mac with opencv)

Or rather, how to experiment with using OpenCV to train a classifier and ultimately fail. The following two links were my guides. They might make better guides than what follows here, but I'm going to write this stuff down for myself. http://docs.opencv.org/doc/user_guide/ug_traincascade.html http://www.prodigyproductionsllc.com/articles/programming/how-to-train-opencv-haar-classifiers/ I wanted to try training my own OpenCV Haar Cascaded Classifier. OpenCV comes with some pre-trained ones for faces and body parts and whatnot. For fun, I tried to train it to recognize my cat Jpeg, which Picasa humorously recognized as a person in a handful of photos last month: Step 1: Download pictures from my own Flickr account I use this python program to get Flickr image urls: https://code.google.com/p/flickrpy/ I added my flickr API key and changed the main of that python file to look through MY pictures for things tagged 'cat'. if __name__ == '__main__':
