A mind map is a diagram used to visually organize information. A mind map is often created around a single concept, drawn as an image in the center of a blank landscape page, to which associated representations of ideas such as images, words and parts of words are added. read more at WikiPedia

    Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

    and npm is the package manager for the Node JavaScript platform.&160; It puts modules in place so that node can find them, and manages dependency
    conflicts intelligently. It is extremely configurable to support a wide variety of use cases. Most commonly, it is used to publish, discover, install, and develop node programs. (https://npmjs.org/)

  • I did create this mind map a while ago, and found it while going through my dropbox folders. Linux server Monitoring “You can't correct something you can't measure” is in version v 1.0.0

    You’ll find in this mind map

    What to monitor, how and the most useful commands to detect what happening on your Linux server.

    Why a mind map?

    A mind map is a diagram used to visually outline information. mind map help you take notes, brainstorm complex problems, and think creatively.

    • Information are summarized efficiently to be usable and accessible,
    • Inter-relationships are clear between the different concepts,
    • It is the most flexible for organizing associative, divergent and convergent thinking (Convergent thinking involves aiming for a single, correct solution to a problem, whereas divergent thinking involves creative generation of multiple answers to a set problem),

  • I use to make mind map to organize my ideas, or to organize huge amount of data in a tree manner. Maintaining your own root server is time consuming, to say the least,  but it will also force you to put your energy in areas where there is a lot of new things to learn. Here I present you a mind map  that contains most of the tools and ideas of what you should monitor on a Linux server.


    This mind map is an ongoing work, that is why it has also a version number in it (v1.0.0). As soon as I will learn new tricks, the mind map will be updated. Your feedback is always welcomed!

    I develop a small PHP code which is able to capture the content of any Joomla! site. It currently fit my need and is in no way at the moment intended to be use as a Joomla! plugin or component.&160; It produce Freemind mind map and save them in XML files (.mm file) and result is displayed using the open source Flash Freemind browser.

    It currently display all sections and categories of my site, articles are omitted as the Flash browser “crash” (too much articles) while the java version of FreeMind works.

    The flash browser has a toolbar lightly visible at the top to help navigation, zooming and search

    Visit my new sub domain now mindmap.waltercedric.com OR the link that wrap it in Joomla (using Joomla! HTML wrapper)


    What it do

    • Code will be release as soon as it is better documented,
    • Full UTF8 support,
    • Fully configurable (configurations file),
    • Developed for being run in an Unix Cron.
