Introduction to React Native

by

React Native underlines a JavaScript framework used in writing real and natively rendering mobile applications for Android and iOS. The framework is based on React, which is Facebook’s JavaScript library used in building interfaces for web applications. Building a mobile application using javascript isn’t anything new. The similar technique has been used in frameworks such as Ionic, Sencha Touch, Phone Gap, Cordova, and the list goes on.

Using Ansible for provisioning

by

Due to the recent increase of personnel at Grio, it emerged the need of having an automated way of setting up new employers’ machines.

Starting with a brand new machine is always a pain for a developer, and setting it takes at least a couple of days if not the whole first week, resulting in big waste of valuable time. Besides, when a developer starts on a new technology it is not always clear which tools are suggested and which ones the rest of the team are using. Therefore, I have been asked to work as a side project on a way to solve such issues.

Optimizing database queries

by

Most projects you will work on will have a database of some sort. For this reason, optimizing your queries allows you to use all that the database provides without having your application try to reinvent the wheel. In this blog, I’ll be using Postgres and Ruby on Rails to demonstrate some ways that you can optimize things. Much of the second section is Postgres specific, but the concepts should apply to whatever ORM you are using. Hopefully by the end you will have learned some new tricks to improve your project.

The Importance of Good Posture for Software Developers

Posture, defined as the position of one’s body while sitting or standing, is something most developers take for granted. The cliche of the programmer hunched over their desk typing away on their laptop is alive and well in many offices. What, exactly, is the problem with poor posture? Is the job necessarily tied to poor back and neck health? What are the long term effects of poor posture? Is there a way to avoid pain down the road?

Tech and Education Today

by

Looking into a classroom today, things might not look much different than they did 10+ years ago. But if you take a closer look, amongst the books and desks, there are computers, smart boards, and iPads. Technology has always had an influence on education, and in the digital age of today, modern tech companies and education institutions are working together to build effective learning tools.

Prototyping with Interface Builder

by

With the acquisition of Next in 1997, a new tool was initiated into the Apple family. Originally known as an enhancement of OpenStep, called NextStep, it caught the attention of the developer community under the name of Interface Builder, as part of the XCode suite. Now about to celebrate its 20th birthday, Interface Builder represents the most powerful IDE to design user interfaces in a development suite. It doesn’t matter if you are writing an app for iOS, Cocoa, tvOS or watchOS; when carefully used, it will save you hundreds of lines of code. For this and other innumerable reasons, many developers, like myself, love this tool.
