# Perks for Go (golang.org)
Perks contains the Go package quantile that computes approximate quantiles over
an unbounded data stream within low memory and CPU bounds.
For more information and examples, see:
http://godoc.org/github.com/bmizerany/perks
A very special thank you and shout out to Graham Cormode (Rutgers University),
Flip Korn (AT&T Labs–Research), S. Muthukrishnan (Rutgers University), and
Divesh Srivastava (AT&T Labs–Research) for their research and publication of
[Effective Computation of Biased Quantiles over Data Streams](http://www.cs.rutgers.edu/~muthu/bquant.pdf)
Thank you, also:
* Armon Dadgar (@armon)
* Andrew Gerrand (@nf)
* Brad Fitzpatrick (@bradfitz)
* Keith Rarick (@kr)
FAQ:
Q: Why not move the quantile package into the project root?
A: I want to add more packages to perks later.

// * These sample sets are small, allowing us to get them
// across the network much faster than sending the entire list of data

# Go CF Environment Package [![Build Status - Master](https://travis-ci.org/cloudfoundry-community/go-cfenv.svg?branch=master)](https://travis-ci.org/cloudfoundry-community/go-cfenv)
### Overview
[![GoDoc](https://godoc.org/github.com/cloudfoundry-community/go-cfenv?status.png)](https://godoc.org/github.com/cloudfoundry-community/go-cfenv)
`cfenv` is a package to assist you in writing Go apps that run on [Cloud Foundry](http://cloudfoundry.org). It provides convenience functions and structures that map to Cloud Foundry environment variable primitives (http://docs.cloudfoundry.org/devguide/deploy-apps/environment-variable.html).
### Usage
`go get github.com/cloudfoundry-community/go-cfenv`
```go
package main
import (
"github.com/cloudfoundry-community/go-cfenv"
)
func main() {
appEnv, _ := cfenv.Current()
fmt.Println("ID:", appEnv.ID)
fmt.Println("Index:", appEnv.Index)
fmt.Println("Name:", appEnv.Name)
fmt.Println("Host:", appEnv.Host)
fmt.Println("Port:", appEnv.Port)
fmt.Println("Version:", appEnv.Version)
fmt.Println("Home:", appEnv.Home)
fmt.Println("MemoryLimit:", appEnv.MemoryLimit)
fmt.Println("WorkingDir:", appEnv.WorkingDir)
fmt.Println("TempDir:", appEnv.TempDir)
fmt.Println("User:", appEnv.User)
fmt.Println("Services:", appEnv.Services)
}
```

Redigo
======
[![Build Status](https://travis-ci.org/garyburd/redigo.svg?branch=master)](https://travis-ci.org/garyburd/redigo)
[![GoDoc](https://godoc.org/github.com/garyburd/redigo/redis?status.svg)](https://godoc.org/github.com/garyburd/redigo/redis)
Redigo is a [Go](http://golang.org/) client for the [Redis](http://redis.io/) database.
Features
-------
* A [Print-like](http://godoc.org/github.com/garyburd/redigo/redis#hdr-Executing_Commands) API with support for all Redis commands.
* [Pipelining](http://godoc.org/github.com/garyburd/redigo/redis#hdr-Pipelining), including pipelined transactions.
* [Publish/Subscribe](http://godoc.org/github.com/garyburd/redigo/redis#hdr-Publish_and_Subscribe).
* [Connection pooling](http://godoc.org/github.com/garyburd/redigo/redis#Pool).
* [Script helper type](http://godoc.org/github.com/garyburd/redigo/redis#Script) with optimistic use of EVALSHA.
* [Helper functions](http://godoc.org/github.com/garyburd/redigo/redis#hdr-Reply_Helpers) for working with command replies.
Documentation
-------------
- [API Reference](http://godoc.org/github.com/garyburd/redigo/redis)
- [FAQ](https://github.com/garyburd/redigo/wiki/FAQ)
- [Examples](https://godoc.org/github.com/garyburd/redigo/redis#pkg-examples)
Installation
------------
Install Redigo using the "go get" command:
go get github.com/garyburd/redigo/redis
The Go distribution is Redigo's only dependency.
