How you can improve code quality in your project?

Last Saturday during my lecture about code quality I was a bit shocked how many people didn’t know the most accessible tools that can improve code quality. You should remember that cost of quality improvements will be low only when we will think about those issues from the early beginning of the project. Every additional day when we are not monitoring and improving quality will increase the cost of potential quality issues fixes in future. Of course, I would assume that each time we are trying to deliver good quality code but we are only humans. So even when we [...]

Sending emails from Azure Functions – SendGrid

I am trying to convince people that right now we should try to think about how we can build our application effectively. Instead of building everything from scratch we should look for possibilities of composition application from different elements. This means that you should write smaller amount of code and there is also smaller chance for making an error. In case of Azure Functions natural choice for email service provider is SendGrid. […]

Azure Function – Uploading photos to Azure Blob Storage

Today I would like to describe another production use case for Azure Functions. This time example is quite simple. I would like to use Azure Functions to upload photos to Azure Blob Storage. Of course, you can upload photos directly to Azure Blob Storage. However, with such solution, your components are tightly connected. This can block you in the future. To avoid that you should add some middle layer. For this, you can use Azure Function. It will act like an API that will accept photos encoder in base64 and upload it to provided location. With this approach, you will [...]

Crisis of productivity – things that you can do not to become a slave of your calendar

It is quite often that I am afraid of things I have to do. And what is even worse I start acting as a firewall – I am busy!!! I am very busy!!! I do not have time!!! I become the slave of my calendar and ToDo list. Even more, there are sometimes tasks that I do not want to do and I am not obliged to do. In such situation, effectiveness became an issue… There are a lot of small matters to do, and there is no time for bigger and more serious ones. Sometimes at the end of [...]

Social costs of mobile applications – based on Pokémon Go

Have you ever thought how enormous cost could be generated by the mobile application? Moreover, I am not thinking only about the cost of development… In most cases, we are saying that the mobile application succeeds when it is downloaded by an enormous number of people. However, nobody is talking about the other side of the medal. The same situation occurred with Pokémon Go. Let’s start with good things. Only in Google Play this game has been download between 100 million and 500 million times. Moreover, you will find over 9,7 million of reviews. Both numbers are still growing. It [...]
