Free mongoDB course

A while back I finished a MongoDB course from MongoDB University. I took it out of curiosity and for fun. MongoDB offer a selection of courses that are available on-line for free. I attended the "MongoDB For Developers" course, which I recommend for developers starting out with MongoDB.
Visit http://education.mongodb.com/ to start out.

A bit about Mongo

MongoDB is a cross-platform document-oriented database system.
Basically that means that you can setup MongoDB on Windows, Linux Mac or Solaris.
MongoDB is document since it works with JSON like documents.

JSON Sample
{"menu": {
  "id": "file",
  "value": "File",
  "popup": {
    "menuitem": [
      {"value": "New", "onclick": "CreateNewDoc()"},
      {"value": "Open", "onclick": "OpenDoc()"},
      {"value": "Close", "onclick": "CloseDoc()"}

As you can see, JSON is a text based document, readable that contains arrays and key-value pairs.

Some things you should know before talking about MongoDB.

  1. Its a NoSQL database. the No stands for Not Only !!!
  2. Mongo comes from humongous, and it can be.
  3. Its easy to start out with and one ban can also accomplish complex problems.
  4. MongoDB has been adopted by a number of major websites and services, including eBay, Foursquare, SourceForge, and The New York Times and many more : http://www.mongodb.org/about/production-deployments/

  3. TV with LED backlighting
    It is easy to backlight TV screens. There are many options for LED light strips, including color-changing and colored ones.

    What you will need:

    We recommend 5050 RGB or Single Color LED Strip for backlighting your TV screen. It has high luminosity, and comes in a variety colors.
    The dimensions of your TV screen will determine the length of the strips. Connect the strips using connectors for LED light strip connectors, particularly around corners.
    The wattage needed to run the strips can be calculated by multiplying its length with the wattage per mile. Example: 5 m of 5050 LED strip light will consume 5.4 w/m = 72w.
    Wireless RF LED strip controllers allow you to control the color temperature, brightness and color temperature of LED light strips.
