AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

Raw Attribute Strings

<div my-directive="some string" another-param="another string"></div>

Graphing Widget

The graphing widget shows graphs using the Rickshaw graphing library. The names of data fields should be (vaguely) familiar if you've used Rickshaw before.

It's recommended that you replace the /assets/javascripts/rickshaw.min.js from your dashboard with the latest from here.

Supported HTML data fields

Reading SBT Credentials from OS X Keychain

In the following, replace the REPO_NAME value with the natural-language name of your repository, replace REPOSITORY with the domain name (e.g. repo1.maven.org) and replace USERNAME with your repository user.

credentials += {
  val Password = """.*password: "([^"]+)".*""".r
  var lines: String = ""
  val logger = new ProcessLogger {
 def info(s: =&gt; String) = {}

doobie experiment - postgres NOTIFY as scalaz-stream

One of the cool things PostgreSQL gives you is a simple notification system that you can use to let clients know that something interesting has happened. For instance you can set up rules that broadcast notifications when a table is updated, and client applications can update displays in response. The JDBC driver provides access to this API so I thought I would see what it would look like in doobie.

The program below constructs a Process[ConnectionIO, PGNotification] that registers for events, polls for them periodically (this is the best we can do with current driver support), and unregisters when the stream terminates for any reason. We use a Transactor to replace ConnectionIO with Task which gives us something we can actually run.
