Some time ago I wrote this short article about co- and controvariance in Kotlin and how these features help the developer to write less error prone code. When I talked with some colleagues about TypeScript, I recognized that, despite some experiences I made with small pet projects, I do no know about type variance in TypeScript. Thus, I decided to take a look and was surprised. TypeScript is not that well-typed as I thought…

GUI Transactions with the FRP Framework Sodium
Sodium is an implementation of Functional Reactive programming (FRP) with some nice features. One of these is the support of transactions in the GUI layer. I had quite some discussions with my colleagues on what this actually means and if such a transaction concept is useful or not. In this article I sum up my current insights and opinions about transactions in Sodium.

Functional Reactive Programming with Angular and Sodium
Functional reactive programming (FRP) is a variant of reactive programming for the development of user interfaces based on the functional paradigm and a strict set of basic operators. In contrast to reactive frameworks, such as RxJs, using FRP enables a developer to define a pure area in her code in which some error classes, typical for event-based architectures, do not occur. Sodium is an FRP-framework, which is independent of a specific GUI-framwork and supports several different programming languages. Here, we describe how to use Sodium together with Angular.
