Website tool for processing language.

The Studio SketchPad aims to be a open studio for individuals learning to sketch beautiful code on the web canvas with  Processing and  EtherPad.
The default licensing adopted for the sketches are the Creative Commons Attribution-ShareAlike 3.0 Unported license.
Today I will come with this tutorial about hoe to use this tool.
First you need to open all three websites from this tutorial.
The Studio SketchPad come with a good web tool to test the Processing Visualization Language with Etherpad.
About Etherpad is a highly customizable Open Source online editor providing collaborative editing in really real-time.
Open your account from Studio SketchPad. From Home menu add your first new sketch from right top of the website. If the website come with the Untitled source code the run it. This will show you how is working.
The base of the processing code is two functions: setup and draw.
The setup function will set all you need to run the draw function.
Let’s see my code:

I put comments into my source code to understand some of the processing language functions.
The variable and math are simple. Variables have a global or local “scope”. for example variables declared outside of setup() and draw() are global variables.
NOTE: If a local variable is declared with the same name as a global variable, the program will use the local variable to make its calculations within the current scope.
You can see the result here and also you can search on my website similar tutorials with processing.

Network and Windows – test your WebSocket Protocol.

This web page will test WebSockets supported in your browser. The test checks WebSocket operation by connecting to the WebSocket-enabled server and exchanging the data.

The web page shows us:
This server supports WebSocket Protocol proposed standard (RFC-6455, December 2011), per-frame-deflate-extension-00 draft, older websocket drafts as well as even older Hixie drafts 75 and 76 (August 2010) with the fix for HTTP reverse proxies.

About then this rfc6455 told us:
The WebSocket Protocol enables two-way communication between a client
running untrusted code in a controlled environment to a remote host
that has opted-in to communications from that code. The security
model used for this is the origin-based security model commonly used
by web browsers. The protocol consists of an opening handshake
followed by basic message framing, layered over TCP. The goal of
this technology is to provide a mechanism for browser-based
applications that need two-way communication with servers that does
not rely on opening multiple HTTP connections (e.g., using
XMLHttpRequest or iframe’s and long polling).

Network and Windows – firefox browser and socks.

This tutorial will explain to you how it works the SOCKS and Firefox browser.
Open one firefox tab with about:config to see the network.proxy.socks_remote_dns value.
If you wan to route your DNS requests through the SOCKS, you’ll need to turn it on.
But because you don’t need to use that then you need to keep to false.
This two result of values will be:

This value controls whether DNS lookups for SOCKS v5 clients happen on the client or on the proxy server.
You can read more about the SOCKS here.
NOTE: Because this use proxy term then you need to know also this about proxy:
– the SOCKS server is a general purpose proxy server that establishes a TCP connection to another server on behalf of a client;
– HTTP proxy is similar, and may be used for the same purpose when clients are behind a firewall and are prevented from making outgoing TCP connections to servers outside the firewall;
