Containers are becoming the standard way of deploying software. Every cloud vendor now offers one or multiple ways to run containers on their platform. Most of our clients uses AWS to host their SaaS solution. As part of a new development for one of our clients we have decided to move away from Elastic Beanstalk and embrace containers. Amazon Elastic Container Service is an orchestration service that supports Docker containers and is generally available for over a year. Given our small development team it seemed like the best choice since it takes away most of the cluster management headaches. In this post I will describe how we deploy a container to ECS using CloudFormation.
Who would not like to be successful and manage their time wisely to have it for everything and for everyone? We all would. But to do that we should focus on our life for a bit longer than few seconds and think which elements of it make us less effective, and in consequence less happy. We should focus on recovering.
If you have ever needed to add a chart to your Android app, you certainly have heard about MPAndroidChart by PhilJay. If not, consider using this powerful library. Let me show you how easy it is to start!
Android resolves language- and culture-specific resources based on the system locale setting. This is a desired behavior that makes perfect sense. Despite it’s officially not encouraged you may still need to write an app that allows the user to change its language without leaving it. In this article I will show you one of the possible ways to implement such feature.
Writing tests is an important skill of a software engineer. I used to write lots of very focused, narrow unit tests. However, I often found such tests to hinder refactoring and barely help in catching regressions. Whether such issues were caused by my poor design choices or are intrinsic to unit tests is not the focus of this post. However, the fact is that nowadays I tend to write more coarse-grained, integration style tests. There is one downside to such approach: speed. For instance, using Hibernate with a full fledged database is relatively slow compared to using a fake repository implementation. Today I write about abstracting the database access using Querydsl in a way that aids testing.
In this post I’m going to focus on connecting React components with Redux. If you are just starting out with React + Redux or you have already worked with these before, but want to make this concept a bit clearer then feel invited to read this post till the end ;)
If we keep track of our daily schedule really thoroughly, we might be shocked how much time we waste in five to fifteen-minute breaks. I am saying “waste” not by accident here since we are often wasting our time during breaks instead of recharging batteries. The good news is that brief mental breaks taken in a reasonable way still help us re-focus, regain motivation and reevaluate goals.
Since Kotlin becomes more and more popular, especially amongst Android developers (and it’s officially supported by Google), some people decided to compare its runtime performance with Java. After reading a few articles I wanted to test it myself and now I’m ready to share some of my observations and experiences.
