Asynchronous programming in C# and .NET is a very powerful tool. And just like any other tool, it can be used incorrectly. This can result in errors in the program that are difficult to debug. In the last part of this series (see the 1st part or the 2nd part), we’ll take a look at the most common mistakes programmers make when …

In this part, we’ll go over the more advanced uses of asynchronous programming with async/await in C# and take a look under the hood to see how it all works. What exactly is an asynchronous method? So far, we’ve shown you how to create an asynchronous method that calls other asynchronous methods. This is the most common case in practice, but …

The use of async/await launched a big boom in asynchronous programming in .NET, mainly because it is so easy to use. But not every developer knows exactly what lies beneath async/await, which can lead to unconscious errors. In this blog series of 3 parts (see the 2nd part, see the 3rd part) we will give you a look under the hood and …

Although, as an expert in information management, he is primarily involved in data warehousing and business intelligence, in recent years, he has also been fascinated by programming languages for children such as Scratch. Read the article by Petr Hájek that summarizes his experiences and impressions from teaching a programming course for children in collaboration with makeITtoday. Many years ago, I got the …

This post isn’t a textbook on data vault modelling. It’s a reflection on what data vault methodology is good for and why it’s worthwhile to take another look at it today. At the very end of the last century, two strong opinions emerged on the structure of data warehouses. Bill Inmon defined the basic principles of data warehouses (subject-oriented, time-variant, non-volatile, and integrated) …

We interviewed our long-time colleague Martin Hlavatý, who has worked at Profinit as a developer, analyst, and team leader and now is our delivery manager. How does he view Profinit, what motivates him to succeed, and how does he think Profinit differs from other companies? How long have you been working for Profinit and how did you get here? I started …

Go to the website ockovani.opendatalab.cz to get an overview of the openings to get vaccinated against COVID-19. The goal of the application is to give Czechs a quick overview of vaccination capacity, which, until now, hasn’t been available anywhere. The application was developed by Marek Sušický and Jan Staněk from OpenDataLab, the joint workplace of the Faculty of Information Technology of …

Build once, deploy many is an essential principle of software development. The main idea is to use the same bundle for all environments, from testing to production. This approach enables easy deployment and testability and is considered a fundamental principle of continuous delivery. It is also part of the twelve-factor methodology. As crucial as it is, it has not received significant …

On my projects, I mostly work with modern Java (11+), but I still occasionally work with older versions (6,7) as well. Every time I switch to an older one, I miss modern Java features, especially those found in functional programming such as lambdas and streams, which I find very useful. Imagine you have an old maintenance project with poor old Java 6 or 7, and …

We held another professional breakfast, this time on the topic of credit forecasting. The breakfast was mainly directed at professionals from the fields of AI, data analysis, and modelling, but we also gladly welcomed directors and managers, especially from the banking sector as they are directly affected by the topics from a business perspective. After all, the highlight of the breakfast …
