/* This is the original elf.h file from the GNU C Library; I only removed

Cross-site Scripting (XSS) is the most prevalent web application security flaw and occurs when user supplied data is sent to the browser without properly validating or escaping that content. XSS flaws can allow the attacker to:

• Deface web page (examples http://xssed.com, http://www.alpacahack.com/)
• Steal session cookies so attackers can impersonate victims without having to steal passwords

Update May 2017

Eric Bidelman has documented some of the common workflows possible with headless Chrome over in https://developers.google.com/web/updates/2017/04/headless-chrome.

Update

If you're looking at this in 2016 and beyond, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

Windows and Mac users might find using Justin Ribeiro's Docker setup useful here while full support for these platforms is being worked out.

WebAudio+WebSocketでブラウザへの音声リアルタイムストリーミングを実装する

WebRTCでやれよ！と言われそうなところですが、 WebSocket+WebAudioの組み合わせで音声ストリーミングをシンプルに構成する方法を紹介してみます。

サーバーサイド(Node.js + ws + pcm)

サーバーサイドは何でも良いのですが、 とりあえずNode.jsでtest.mp3というサンプルファイルをpcmモジュールでデコードし、 wsでクライアントに垂れ流す作りにしておきます。
