Convista Poland history from CEO perspective
Wioleta Patkowska (HR Manager): Could you tell me how it all started? Paweł Midoń (CEO): It started in the year when the first iPhone was released. It’s good that I didn’t know what I know now: how much the world of IT and technology would change. I thought I could create a company that would give customers and employees something exceptional: something they really needed. Today I know it’s called User Experience. But let’s start at the beginning. While working as an IT consultant, I noticed that: Customers expect a real understanding of their needs. They do not want to be put in the standard table (compartmentalisation). Clients do not want to work with a consultant from Company X, but with a person who has a name, surname, face, and competences:…

Managerial practices in the eyes of employees
Wioleta Patkowska, HR Manager: Let me start by asking you about an exceptional manager who played a role in your professional career. Who were they? Agata Bandych (HR Specialist): An expert I could trust because they knew what they were doing and did not stumble in their work. Even if I didn’t agree with something, I could back off because I trusted their competence and knew there was a greater purpose behind their decisions that I may not have yet understood. They also never gave me the impression that they were too busy to talk to me. Every time I needed help, they did their best to be available. Malwina Nagórska (SAP Architect and Coach): A leader with a human face. They were able to admit that they didn’t get something…

How to create reusable components in SAPUI5 and is it worth it?
Introduction Fiori allows to create different types of applications – using Fiori Elements or simply Freestyle applications.

Basic-Auth is deprecated. How about OAuth 2.0 and OpenID Connect?
In this article, you will learn the basics of the OAuth 2.0 authorization framework and a simple identity layer which located on top of the framework – OpenID Connect. Introduction Before OAuth, the common pattern for granting access to an external application’s account was to simply give it your password and let it act as a you. Communication always consisted of entering the user’s password in the application and then using it to get access to a particular service with data. Thus, the application was given access to the entire user account, even though in truth it only needed access to part of it – the scope was much broader than realistically needed. Once the application has obtained the user’s password, it is granted…

OAuth, SAML, OpenID – Managing Authentication for Multiple Platforms
Nowadays security has become more important than ever. Implementing the right standards is required for applications to grant access to resources in an expected way. Oftentimes instead of implementing your own solutions, it is possible to apply proven standards that the industry has been using for years. This approach might yield numerous benefits, such as: the economy of time; hassle-free implementation due to broadly available documentation; much easier solving of problems as communities using the same solutions are keen on sharing their knowledge, in most cases continuous support and adaptation to changing standards; and above all, the safety of using a proven, tested solution. Therefore, should you be interested in ready-made standards and management of authorisation for many platforms, it is worth…

Creating Users Dashboard with SwiftUI
In this article, you’ll learn the basics of the SwiftUI framework, which was created in 2019 by Apple and is now gaining on popularity, slowly replacing UIKit in building iOS-apps views.

Look at the picture no. 1 Stacks In all views created with SwiftUI, we can observe one basic pattern. Each contains Stacks in three axes: Vertical – VStack, Horizontal – HStack and along the Z-axis – ZStack. They allow us to simply arrange the sub-views and organize them on the screen. With their help we will build the already…
