Cube

Time Series Data Collection & Analysis Cube is a system for collecting timestamped events and deriving metrics. By collecting events rather than metrics, Cube lets you compute aggregate statistics post hoc. It also enables richer analysis, such as quantiles and histograms of arbitrary event sets. Cube is built on MongoDB and available under the Apache License on GitHub. Collecting Data An event in Cube is simply a JSON object with a type, time, and arbitrary data. Cube’s collector receives events and saves them to MongoDB. Querying Events Cube defines a simple language for querying events. You can intersect filters and customize which event fields are returned. request(browser).gt(duration, 250).lt(duration, 500) Cube supports both HTTP GET and WebSockets for retrieving events. Querying Metrics You can also use Cube to group events by time, map to derived values, and reduce to aggregate metrics. The first few results of which appear as: sum(request.eq(path, "/search")) sum(request(duration))

From simple line charts to complex hierarchical tree maps, the chart gallery provides a large number of ready-to-use chart types. The most common way to use Google Charts is with simple JavaScript that you embed in your web page. That's all you need to get started. Charts are exposed as JavaScript classes, and Google Charts provides many chart types for you to use. All chart types are populated with data using the DataTable class, making it easy to switch between chart types as you experiment to find the ideal appearance. Ready to create your first chart? Our tools are constantly evolving to better address your needs; we depend on your feedback to help us prioritize which features to include.

tbranyen/backbone-boilerplate - GitHub Mondrian Documentation Developer's Guide There are several ways to get Mondrian running. The easiest is to download a binary release, as described in the installation guide. But you can also build Mondrian from its source code. This document describes how to do that, how to learn about Mondrian's inner workings, and the guidelines you'll need to follow if you want to contribute to the Mondrian project. Getting the source code First, you need to get a copy of the source code. Download the latest release Download the latest mondrian-version.zip from SourceForge, and unzip. Clone the Github repository Download the Git client from Git. Clone the Git repository. $ git clone Cloning into 'mondrian'... remote: Counting objects: 51661, done. remote: Compressing objects: 100% (9979/9979), done. remote: Total 51661 (delta 37833), reused 51512 (delta 37691) Receiving objects: 100% (51661/51661), 294.25 MiB | 604 KiB/s, done.

Springy - A force directed graph layout algorithm in JavaScript. Jed | Gettext Style i18n for Modern JavaScript Apps Gettext Style i18n for Modern JavaScript Apps Gettext? Gettext is an old translation standard. Safety and Speed Jed parses plural forms using a grammar instead of running eval. You can find a fairly comprehensive list of plural forms here: translate.sourceforge.net/wiki/l10n/pluralforms Sane API Wrappers Sometimes using gettext directly is fine, but knowing which gettext function to call at runtime can often be cumbersome. Jed API The core available functions on an instantiated Jed object are: translate( key ) - Sets the key to translate (often english). onDomain( domain ) - Sets the domain to use in the locale_data. withContext( context ) - Specifies the context prefix for key lookup. ifPlural( num, plural_key ) - Specifies the plural translation path and plural value. fetch( sprintf, style, args ) - the values to interpolate into the response. Jed also exposes all the standard Gettext functions on an instance. Installation Node npm install jed Then in your app: var Jed = require('jed'); Details
