This jQuery plugin generates sparklines (small inline charts) directly in the browser using data supplied either inline in the HTML, or via javascript.

The plugin is compatible with most modern browsers and has been tested with Firefox 2+, Safari 3+, Opera 9 and Internet Explorer 6 & 7.

Juicer is a command line tool that helps you ship frontend code for production.

High level overview; Juicer can

* figure out which files depend on each other and merge them together, reducing the number of http requests per page view, thus improving performance
* use YUI Compressor to compress code, thus improving performance
* verify that your JavaScript is safe to minify/compress by running JsLint on it
* cycle asset hosts in CSS files
* add "cache busters" to URLs in CSS files
* recalculate relative URLs in CSS files, as well as convert them to absolute (or convert absolute URLs to relative URLs)

XHProf is a function-level hierarchical profiler for PHP and has a simple HTML based user interface. The raw data collection component is implemented in C (as a PHP extension). The reporting/UI layer is all in PHP. It is capable of reporting function-level call counts and inclusive and exclusive wall time, CPU time and memory usage. Additionally, it supports ability to compare two runs (hierarchical DIFF reports), or aggregate results from multiple runs.

Originally developed at Facebook, XHProf was open sourced in Mar, 2009.

Library to implement a well-behaved Unix daemon process.

This library implements the well-behaved daemon specification of PEP 3143, "Standard daemon process library".

A well-behaved Unix daemon process is tricky to get right, but the required steps are much the same for every daemon program. A DaemonContext instance holds the behaviour and configured process environment for the program; use the instance as a context manager to enter a daemon state

dropr is a distributed message queue framework written in PHP. The main goals are:

* reliable and durable (failsafe)-messaging over networks
* decentralized architecture without a single (point of failure) server instance
* easy to setup and use
* modularity for queue storage and message transports (currently filesystem storage and curl-upload are implemented)

Jester is a JavaScript implementation of REST, with syntax modeled after ActiveResource. You can use it to write code to read, create, and update the data on your server.

* Great Syntax – If you’ve gotten used to dirt-easy syntax like ActiveRecord’s “User.find(1)” for getting records, you can look forward to the same simplicity in Jester. Wherever possible, Jester takes advantage of JavaScript’s flexibility to keep things simple.

* Associations – Jester supports and reflects your Rails associations, detecting them automatically if your server includes them in its output.

* Plays With Others – Jester supports “JSONP”, a format for JSON that allows your API to be shared with JavaScript remotely. Sites like Twitter that support this work perfectly with Twitter, with minimal configuration on your part.

* Dependencies – Prototype, a server that uses RESTful URL and format conventions as popularized by Rails and ActiveResource. In Rails, a controller whose routes are defined using “map.resources” will work with Jester with no extra configuration.
