  • How to install Hadoop?

    - by Anitha
    I am trying to install Hadoop in Ubuntu 12.04 version. Following the instructions from http://michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/, I installed java-6-openjdk from Ubuntu software-center.

  • Is there a Railstutorial-quality tutorial for a PHP framework?

    - by tnorthcutt
    Is there a tutorial along the lines of Michael Hartl's Rails Tutorial for a (widely used) PHP framework? Obviously there are tons of tutorials for e.g. Codeigniter, CakePHP, Symfony, etc., but I haven't been able to find one that is as extensive as Rails Tutorial is. Ideally, I'd like something that takes you from nothing to building a complete, functioning application with at least a decent amount of complexity.

  • A TDD Journey: 1-Trials and Tribulations

    Test-Driven Development (TDD) has a misleading name, because the objective is to design and specify that the system you are developing behaves in the ways that the customer expects, and to prove that it does so for the lifetime of the system. It isn't an intuitive way of coding but by automating the specifications of a system, we end up with tests and documentation as a by-product. Michael Sorens starts an introduction to TDD that is more of a journey in six parts:

  • A TDD Journey: 4-Tests as Documentation; False Positive Results; Component Isolation

    In Test-Driven Development (TDD) , The writing of a unit test is done more to design and to document than to verifiy. By writing a unit test you close a number of feedback loops, and verifying the functionality of the code is just a minor one. everything you need to know about your class under test is embodied in a simple list of the names of the tests. Michael Sorens continues his introduction to TDD that is more of a journey in six parts, by discussing Tests as Documentation, False Positive Results and Component Isolation.
