Ruby の HTTP クライアントライブラリ Faraday が便利そう

Ruby の HTTP クライアントライブラリ Faraday が便利そう

API ラッパの開発には [RestClient gem][rest_client_gem] だとか
OAuth の必要なものは [Net/HTTP][net_http] + [OAuth gem][oauth_gem] を使ってた

[Twitter gem][twitter_gem] や [Instagram gem][instagram_gem] など API ライブラリのソースを読んでみると
[Faraday gem][faraday_gem] というものがよく使われてた

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
