Piwik is a PHP MySQL software program that you download and install on your own webserver. At the end of the five minute installation process you will be given a JavaScript code. Simply copy and paste this tag on websites you wish to track (or use an existing plugin to do it automatically for you) and access your analytics reports in real time.
Or if your own Piwik server is on the internet, you can use client side tracking there, too. For that, you'd just be following the instructions on Piwik's site to embed the tracking javascript into your portal_norma.vm file and you should be good to go...
Toda esta integración es para no emplear el JavaScript, que es la forma normal y recomendable de emplear Piwik + Liferay Portal
Note that the tracking cookie name is defined in the global piwik configuration (global.ini.php) and the default value does not match the cookie name the code is looking for (a string that contains "id.#.", where the # is the site id), so you'll probably need to make modifications to the code to match the global.ini.php configuration before using it.
LESS Permite el desarrollo de CSS mediante extensiones que permiten el uso de variables, herencias (de clase), anidamientos, y mucho más.
Para usarlo... o se carga un JS en el navegador... ¡o se compila!
El programa npm está disponible como paquete en Ubuntu :-D
Permite incluir un JS en las páginas y hacer análisi de tráfico de una web, no sólo por páginas (como Google Analytics), sino también dentro de la página (movimiento de ratón, zonas de click, etc.)
