Kotlin language provides a nice and clean way to handle nullable variables in code so that it is less error prone. Unless you do it all wrong, of course.
Last week I attended a climbing competition dedicated for girls only to celebrate the international women’s day. It was held quite far away from my home town and on my way back I was wondering why I was so excited to attend a climbing competition for women and at the very same time I am so sceptical about any girls-only programming events.
Serverless deployments are popular these days. With a minimal cost you can have your own code wait and respond to various events. AWS Lambda, Azure Functions are just 2 examples of serverless offering from the biggest cloud providers. For a long time I had thought about them only in the context of ad-hoc setups not suitable for a long term development. This was until I found out that you can, with a little effort, version and deploy the serverless API just as a traditional back-end. In this post I am going to show how to deploy AWS Lambda functions with the help of the tool Adam created at Bright Inventions called cloudform.
Have you ever heard about Groupthink? It occurs when a group of people make faulty decisions due to mutual pressure. According to Irving Janis who coined this term for the first time in 1972, the group pressure leads to a deterioration of mental efficiency, moral judgement as well as reality verification. Groups affected by the groupthink phenomenon frequently ignore alternatives while looking for a solution. People who are vulnerable to groupthink mostly have a similar background, work in organisations with a lack of established decision making process and do not meet any outside opinions.
A service running ECS can call plethora of AWS APIs. It can read messages from queues, publish messages to SNS topics, query a database. These are all valid ways to communicate with the service. However, often the most appropriate way is to call the service by an HTTP API. In this post I’ll describe how to configure an ECS service running inside VPC so that other services can call its API.
In the previous post I did show you how to make a basic setup of Android linear chart using MPAndroidChart library. Now I’ll show you some features I found useful.
Default iOS build configurations, Debug and Release, might be enough for the beginning, but sooner or later you will probably need to extend the number of build configurations in your app. While this is pretty straightforward in native development, unfortunately, it is not in React Native.
There is always a room for improvement regarding the service that we deliver to our clients. In this post I describe 3 habits that I consider really helpful in order to work effectively with clients.
