TO HAVE OR TO BE?
While learning object-oriented programming, and after mastering the basics of objects, fields and methods, one spends most of the time on inheritance. Inheritance means that we acquire some part of the implementation from a base class. You just have to create a subclass of a base class i order to inherit every non-private field and method.
BDD ON RAILS
Today’s programmers use more and more agile practices in their everyday work. Even projects following standard software development life cycle can benefit from adapting them. Automatic testing and TDD brought more confidence to our work, facilitated implementing modifications to existing features and often lead us to better code design. But now it’s not enough. We have to push the benefits from tests to the limits and BDD allows that.BDD builds on top of TDD and adds to its practices a lot of value. It brings ubiquitous language to the project, allows for better communication between client and developers. It offers a lot for project managers and leaders, but also makes life of a developer a lot easier. Following BDD principles gives us clear requirements, tests are easier to understand and they can serve as documentation. BDD shifts focus of testing subjects and gives us confidence that we test what we should be testing – behaviour.
SHADES OF EXPRESSION - MONOCHROMATIC WEB DESIGN
Colour theory in the psychological field is used to determine the impact of a certain form on a person. It is well known for designers that shape or content can be misunderstood when their colours are wrongly chosen.
MAINTAINING DATABASE STRUCTURE AND WORKING ON MULTIPLE BRANCHES
Developing an app does not only mean implementing new functions or patching it. Sometimes you have to reverse the changes and go back to the previous stage of a project. A frequent issue that can come up while working on multiple branches is connected to maintaining the appropriate version of a database structure. Programmers, who use rails, have ready-made solutions at their disposal. These solutions support the implementation and control of database changes - these are migrations. I will not describe how it works and what possibilities it brings - I would like to focus on the problem of maintaining the appropriate version of a database structure while switching branches.
REPLACING THE ASSET PIPELINE WITH GULP
Where does this idea come from? Why would someone want to drop the Asset Pipeline off? You may ask yourself what is wrong with it?
HOW TYPOGRAPHY AFFECTS THE USER’S PERCEPTION OF THE WEBPAGE
Ever since I noticed that the application we prepared has expanded significantly, I have decided to find a completely new method for automation of the process of its launching.
VECTOR GRAPHICS ON WEBSITES
On the Internet you can read a lot about interesting Internet of Things (IoT) projects, based on Arduino and Raspberry Pi.
