Initial tasks in PL

Tasks:

All of these tasks are explained for use it in Ubuntu:

1. Install git
2. Introduction to node.js
3. Install and use Pandoc

1 install git

In ubuntu install git in very simple. Open your bash terminal and use package manager like this:

$ sudo apt-get install git

To ensure it is installed correctly,: write in your terminal:

$ git --help

And you see something like this:

2 Introduction to node.js

Little tutorial to install and example of use node.js based on the tutorial of the officia page(see fonts section)

###Introduction Node.js is an open source, cross-platform runtime environment for server-side and networking applications. Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, Linux, FreeBSD, and IBM i.

Node.js provides an event-driven architecture and a non-blocking I/O API that optimizes an application's throughput and scalability. These technologies are commonly used for real-time web applications.

Node.js uses the Google V8 JavaScript engine to execute code, and a large percentage of the basic modules are written in JavaScript. Node.js contains a built-in library to allow applications to act as a Web server without software such as Apache HTTP Server or IIS

###Instalation 1-First run http://nodejs.org/
2-Push install:

3-When the file is downloaded open shell and put the following commands:
To decompress:
$ tar xzvf node-v0.10.36.tar.gz
To install:
$ cd node-v0.10.36
$ sudo make $ sudo make install
$ sudo ./configure
Delete temporary stuff:
$ cd .. $ rm -rf node-v0.10.36.tar.gz node-v0.10.36
We have now installed node.js

###Ejamples of use This simple web server written in Node responds with "Hello World" for every request.

var http = require('http');  
http.createServer(function (req, res) {  
  res.writeHead(200, {'Content-Type': 'text/plain'});  
  res.end('Hello World\n');  
}).listen(1337, '127.0.0.1');  
console.log('Server running at http://127.0.0.1:1337/');  

To run the server, put the code into a file example.js and execute it with the node program from the command line.
$ node example.js
Server running at http://127.0.0.1:1337/

And you can see in http://127.0.0.1:1337/

Here is an example of a simple TCP server which listens on port 1337 and echoes whatever you send it:
$ node

And write:

>var net = require('net');

>var server = net.createServer(function (socket) {
  socket.write('Echo server\r\n');
  socket.pipe(socket);
});

>server.listen(1337, '127.0.0.1');

Then you can see the petition of the browser, in http://127.0.0.1:1337/

you can change server configuration inline with command node. This produces a
loop where the code are written and executed in real time.
