Django's default tests fail

Filed under: Django   home  

This bug has caught me a few times so I figure I'll share it. The default tests fail with errors like:

AssertionError: False is not True : Couldn't find 'Message 1' in response
...
KeyError: 'user'

These two failures occurred when I added the authentication and messages middleware but not their template context processors. In settings.py I needed something like:

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
)

TEMPLATE_CONTEXT_PROCESSORS = (
    'django.contrib.auth.context_processors.auth',
    'django.contrib.messages.context_processors.messages',

)

Hopefully this helps someone out there.

Filed under: home   Startups   YCombinator  

The first time I went through YCombinator, it was in a batch of 14 companies. The most recent batch 59 demoed (39 publicly). They've outgrown the YCombinator demo space and have moved to an auditorium in Mountain View's Computer History Museum - with a seating capacity of 380.

I was lucky enough to attend YCombinator's Alumni Demo Day last night (where the startups do a practice run-through of their pitches). Here's a quick summary of the public companies with my thoughts:

Touch-screen bus

Filed under: hacking   home  

When I was 17 my brother asked me to build a touch-screen interface for a bus he had recently purchased. The screen was to serve as the dashboard, controlling the turn signals & headlights, starting the engine, opening the door, etc.

To complete this project I used a rabbit embedded microcontroller similar to the SBC BL4S200. You can get one for as little as $250 today. A budget computer connected to the touch screen via USB & VGA and communicated with the microcontroller via a serial port. I then reverse-engineered the relays on the bus to determine their function (ie, power the ... more

sam.odio.com has a new blog.

Filed under: home  

Since moving off Blogger (here's why) and loosing all of my blog's comments my blog has fallen into a bit of disuse. Now that I'm freshly unemployed (at least, that's how my Dad calls it) I aim to change that.

Action items:

1. Create an open source lightweight django blog.
2. Crowd-source a blog design using crowdspring.
3. Realize that crowd-sourcing is a failure, convince Michael to donate his time and patience to fix it.
4. Port all old blog posts to new platform.
5. Port all comments (which have recently disappeared) to new platform.
6. Make myself a Margarita and relax ... more
