Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Fast and flexible unit tests with live Postgres databases and fixtures

I've created a Pyramid scaffold which integrates Alembic, a migration tool, with the standard SQLAlchemy scaffold. (It also configures the Mako template system, because I prefer Mako.)

I am also using PostgreSQL for my database. PostgreSQL supports nested transactions. This means I can setup the tables at the beginning of the test session, then start a transaction before each test happens and roll it back after the test; in turn, this means my tests operate in the same environment I expect to use in production, but they are also fast.

I based my approach on sontek's blog post, but I've refined it a bit.

I use py.test for unit tests, but to the best of my knowledge, a similar approach will work with nosetest; you just create a nosetest plugin to load in the ini file with a command line option, and have begin

	server 127.0.0.1:5000;
	}

	server {
	listen 80;
	server_name my_site.localhost.com;

	root $static;
	keepalive_timeout 60;

	# Update 7 Oct 2010:
	# - This example does not appear to work with Chrome >=6.0. Apparently,

	# well with Chrome's (newer) WebSocket implementation.

	# Requirements:
