In this quick tutorial we’re gonna leave the more technical topics to land into the Agile world, a methodology that allows us as startuppers to quickly adapt to frequent and unpredictable changes in projects’ requirements.
The Agile movement takes origin in 2001 from the experience of some prominent Software Developers who taught us some principles in Software Development which can make life easier for developers, deliver value to customers, build successful software projects. Among them we find Kent Beck, Martin Fowler, Robert C. Martin, Ward Cunningham, as first signatories.
You can discover the others, as well as the movement’s 12 core principles at the following website: the agile manifesto.
In the last two episodes we saw how to create a simple web application using either Symfony or Laravel. Let’s do the same with Ruby on Rails. In this tutorial we’re gonna combine also another competence we developed in this series of tutorials: Docker.
Now that you have all up and running, all you have to do is to create a Ruby on Rails stack on your computer. Let’s start by creating a Docker file, so create a directory named rails_tutorial and put the following content on a file called Dockerfile (without any extension):
In this simple tutorial I’m gonna teach you some basic tricks about a skinny LAMP application containerized with Docker.
One of the main focuses of Docker is to solve a common problem in developing and deploying complex applications, which is known as “The Matrix from Hell”.
When designing an application stack which is more than trivial, you have to take care of the compatibility between different version of tools and languages and their dependecies, which have to coexist in the same machine.
With Docker, you solve this problem by instantiating different light-weight machines in a single host, without the need to create real virtual machines on the cloud and spending a lot more: a Docker container consumes a lot less resources.
In this tutorial, which is meant for beginners, I’m gonna teach you the fundamentals of Angular 2, and in particular how to create a new component, the first thing when learning this framework.
These are the prerequisites: if you haven’t done before, go ahead and install Node.js https://nodejs.org from the main website, bundled with it you will find NPM, which is node package manager, you’re gonna need it. Then check if the installation was correct:
In this mini tutorial I’m gonna show you a little trick which can be useful in order to create a new bundle in Symfony.
If you choose to create a bundle yourself, there might not be problems, but if you want to use the bundle creator tool of Symfony, you may encounter some difficulties that can make you loose precious time.
The first thing is to install Symfony, on your computer, here is the documentation: https://github.com/symfony/symfony-installer, but you can also follow this tutorial. We suppose we’re on Linux, but there’s a similar procedure on Windows:
The Twitter API is one of which I love the most. Its simplicity and richness of functionalities make it a worthwhile experience for a programmer to do.
First and foremost you need to import the library into your Java project, you can do it with Eclipse via Maven, or you can use your preferred IDE, you can also import the library in your Android application through Gradle. Here is how to do it:
