What comes to mind when you describe “your product”? Do you think about features built for your customers? How it solves a problem your customers have? Maybe even a logo, a slogan, or its theme color?
These aspects describe your product’s business side and value proposition. However, they fail to mention the foundation of your product: its software.
The reason you might have forgotten about the software part lies in the fact that product development tends to revolve around the central question:
Which feature should we build next?
Answering this question is undoubtedly a critical step in product development. It…
In a personal project of mine, I regularly fetched data collected by bicycle counting stations scattered around Cologne, Germany, and stored the data in a public GitHub repository. I ran the Python script which was fetching, appending, and uploading the data to GitHub manually for a while, but since I (am lazy and) wanted to always offer the latest data, I thought about how I could automate this process. Here’s how I accomplished running the reoccurring process with GitHub Actions.
At first, I thought about using the popular Oban library written in Elixir to run a reoccurring job, but every…
My team at Studitemps and I ran into the problem that we had multiple services, which needed to be served from the same URL. We had one service running the Elixir + Phoenix stack that we considered our “main service”. This service should be accessible under an URL like
https://example.com. We also had another service serving our content, which we wanted to integrate into the navigation bar of our main service. We wanted the content service to be accessible under e.g.
Here at Studitemps, we have to comply with many rules and regulations that we have to be certain are followed by our software as well. These business requirements have to be poured into production code 1-to-1. Otherwise, we risk losing our students, customers, and at worst, our license.
Therefore, we have to make sure that our software behaves in certain ways. We have developed a process of extracting and implementing business requirements and to make sure that our software will always operate as needed, even when we develop our software further.
Before we can implement business requirements, we have to…
Writing code is fun, but nothing tops seeing your code moving things in the real world. That’s why I tested out the Nerves library and used $20 of Raspberry Pi utensils to let software wave a flag for me.
For this project, I used the following hardware:
Here’s an overview of how to connect the ULN2003 to the Raspberry Pi.
With Phoenix LiveView, adding interactivity and displaying state changes without reloading the page becomes trivial. The complexity and loss of productivity due to context switching decreases significantly by eliminating…
