A little more than one year ago, I took the challenge to write a modern real-time Redis GUI in order to improve my workflow with Redis and to help me write, debug and monitor my Redis servers at Bringr, a real-time monitoring and publishing solution for creating value from social media activity.
Redsmin now helps daily thousands of developers around the world speeding up their workflow.

There are no easy way to do a one-time expression evaluation with AngularJS. The easiest way would be to code a directive but it's most of the time better to not reinvent the wheel.

Bindonce is a small library for AngularJS that provides one-time evaluation (thus zero watchers) for AngularJS. Since Bindonce 0.2+, it's now possible to evaluate any kind of attributes thanks to bo-attr-*.

Let's say we use bootstrap and want to specify dynamically some content generated by JavaScript inside our popover. Using bindonce we just have to write

<div bindonce ng-controller="MyCtrl">

  <div bo-attr 
       bo-attr-data-content="content" 
       bo-attr-data-html="isHtml" 
       bo-attr-data-title="title" 
       bo-attr-data-placement="placement" 
       data-toggle="popover">
    <i class="icon icon-question-sign"></i>
  </div>

</div>

Title, isHtml and content will be evaluated only one time and put inside attr-data-* attributes. From this point we could write our own directive to abstract the creation of our bootstrap popover but that's another story.

After upgrading Cassandra from 1.2.9 to 2.0 and Java from 1.6 to 1.7 (because Cassandra 2.0 does not work with Java 1.6 anymore), I got the following error while running nodetool: Could not find or load main class org.apache.cassandra.tools.NodeCmd
I could not find anything so here is a quick fix: nano `which nodetool`
/* replace */
for include in "`dirname "$0"`/cassandra.in.sh" \
/* with */
for include in "$HOME/.cassandra.in.sh" \
And then nodetool should work like a charm.

Update: The same trick works when cassandra-cli throws Error: Could not find or load main class org.apache.cassandra.cli.CliMain
