Moving Concourse Pipelines

Currently concourse does not support moving pipelines between teams via fly CLI. There is an issue for that here

The only way to do this is to make a few changes in the DB.

If you run the statement below you will see that 6 tables have the team_id column.

concourse=> select table_name                                                                                                                                                                                                                                                                                                                                                       from INFORMATION_SCHEMA.COLUMNS

I wanted to figure out the fastest way to load non-critical CSS so that the impact on initial page drawing is minimal.

TL;DR: Here's the solution I ended up with: https://github.com/filamentgroup/loadCSS/

For async JavaScript file requests, we have the async attribute to make this easy, but CSS file requests have no similar standard mechanism (at least, none that will still apply the CSS after loading - here are some async CSS loading conditions that do apply when CSS is inapplicable to media: https://gist.github.com/igrigorik/2935269#file-notes-md ).

Seems there are a couple ways to load and apply a CSS file in a non-blocking manner:

This configuration is not maintained anymore. You should think twice before using it, Breaking change and security issue will likely eventually happens as any abandonned project.

Setup

git clone <repo>
  clone the repository specified by <repo>; this is similar to "checkout" in
  some other version control systems such as Subversion and CVS
