## notes.txt
my notes on django static assets during development. This is not related to collectstatic or configuring the webserver:

1) created new /static/ directory under 'mysite'
2) put some stuff in there... css, images

How to include in templates:

1) Using the {{STATIC_URL}} seting

    --requires Zero additional configuration unlike {% static "blah.css" %}

## state_is_a_bug.txt
Joe, thanks for responding.

I'm most interested in what are perhaps pedestrian issues, but they're issues (for me) nonetheless. You mentioned "outsourcing" session management... where can I read more on that?

Take the simple case of: I'm a user on your system. I'm logged in. I'm doing things.  The server I'm on disappears while the screen I'm reading is currently loading.

What happens? Do I see an error? Am I sent to a new machine, with all my session state in tact, and the screen I was reading simply reloads?

Or take perhaps a different architecture where a machine isn't brought down until all its users have been successfully moved to other servers. For example, perhaps our configuration is such that we have N instances, and we do a rolling code push to those instances. User A is on Server 5, which has the old code. We need to get that user to Server 2, which has the new code, along with all of his state. Once all users are off of Server 5, the deploy then moves to Server 5 as well and then Server 5 is b

## famine.sql
During the great alphabet famine of two thousand aught six, column names were abbreviated to near-non-readability. In order to automate tests of [newsystem] reports against [oldsystem] reports, we're retaining those column names here. You're welcome.
