Dynamic Octopus configuration for master/slave horizontal DB scaling with a Rails application on the Heroku stack. See the wiki page for more info: https://github.com/tchandy/octopus/wiki/Replication-with-Rails-on-Heroku. Props to Heroku for the idea, gleaned from the dynamic database.yml they inject at build-time for rails apps.

Unfortunately, searching for "golang copy file" gives subtly wrong code snippets (e.g. https://groups.google.com/d/msg/golang-nuts/JNyQxQLyf5o/kbGnTUK32TkJ that don't check close error code). This is an attempt to copy file content from `src` to `dst`
package cp
import (
"io"
"os"
)
func cp(dst, src string) error {
s, err := os.Open(src)
if err != nil {

Example of how to dynamically set a rails secret_token per-heroku app instance. This sets a heroku environment variable on deployment, which is attempted to be read as a secret_token key file. If the token is not found, a new one is generated on the fly (draw back here is that a dynamic secret_key is used every time the app restarts, causing all…

Support routine for adding W3C user timing events to a site. Includes some basic polyfill support for browsers that don't support user timing or navigation timing (though the start time for non-navigation timing support could be improved with IE < 9 to use IE's custom start event).
// Support routines for automatically reporting user timing for common analytics platforms
// Currently supports Google Analytics, Boomerang and SOASTA mPulse
// In the case of boomerang, you will need to map the event names you want reported
// to timer names (for mPulse these need to be custom0, custom1, etc) using a global variable:
// rumMapping = {'aft': 'custom0'};
