  3. Documenting vTiger CRM mobile API

    As there little documentation about vTiger CRM mobile API (not to be confused with vTiger Webservices, which are fairly documented in the wiki) I decided it was time to make my notes public. 

    To do so, I published a repository here: https://github.com/gixWorks/vtiger-mobile-client-ios

    It currently contains only documentation, but I aim at distributing Objective-C code at some point, namely when I will be able to provide a library that it is decoupled from my application’s code and reusable enough by other developers.

  8. What is Ruby on Rails and what is not. (Republished)

    I republish here my blog article first appeared on the Code 4 Indische Buurt project blog [LINK] about what Ruby on Rails isn’t and what it’s not, and why it is important to learn it (and why it may not be important to you).

    I would like to spend a couple of minutes to enlighten a little bit about what Ruby on Rails is… and what it isn’t.

    Ruby is a programming language, just like Java, PHP, C# are.

    Rails is an open source framework for the Ruby language, designed to build web applications.A framework is a set of “tools” that are available for a certain programming language to make life easier for programmers when developing certain kinds of applications. Example of web application frameworks for other programming languages are CakePHP or Symfony (among many others) are web frameworks for the PHP programming language, and ASP.NET MVC is a web framework for the C# and the Visual Basic programming languages.

    When we refer to a web application, we think of a software that runs on the web built to offer certain functions to its users. As an example, the Twitter application offers to users the possibility to write and send 140-characters messages, and much more (think of all the functionalities that Twitter offers). AirBNB.com is a web application that allows people to rent and offer their houses/rooms as vacation places at its core, among many other functionalities. SamensApp, built by the Code for Europe fellows in the Indische Buurt, is a web application that allows people to book spaces in the neighborhood and booking managers to keep track of such bookings.

    On the other hand, Ruby on Rails cannot be put in comparison to softwares such as WordPress, Drupal or Joomla. These are web applications themselves and, although often people use them as “frameworks”, they are complete web applications built for offering certain functionalities, mainly for blogging and content management.

    What do I mean with this? I mean that if we are looking for a software to publish a blog, it would take less time to just install WordPress, which comes for many built-in functionalities especially for building a blog.

    However, if you were to build a “next generation” application to rival Twitter, or if you were to build a web application where users can plan their travels and then share them with other people (a “Travellers community”), then using software such as WordPress would impede your work in many ways: you would have to go against how it was designed in the first place, before you get it to do what you really need.

    In that case, building a web application from scratch is the best solution.

    And here is where Ruby on Rails comes in.
