I've written a simple Python class for creating daemons on unix/linux systems. It was pieced together for various other examples, mostly corrections to various Python Cookbook articles and a couple of examples posted to the Python mailing lists. It has support for a pidfile to keep track of the process. I hope it's useful to someone.

Open Source Search Comparison

Elasticsearch

Main Web: http://www.elasticsearch.org/
Development URL: https://github.com/elasticsearch/elasticsearch
License: Apache 2
Environment: Java

Elasticsearch was created in 2010 by Shay Banon after forgoing work on another search solution, Compass, also built on Lucene and created in 2004.

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

Description

Weatheroutlook Dashing Widget displays a 5-days weather outlook from Yahoo! Weather using Climacons Font.
