The Kotlin programming language has seen an increase of adoption since its launch in 2011. In late 2017 Google announced first-class support for Kotlin on the Android platform which further popularized the language. With this increase in popularity we felt it was interesting to investigate how Kotlin affects the developer experience. We performed a case study to see how Java developers perceive the Kotlin language, and how it meets the requirements of these developers. To gather the developer requirements and their perception of Kotlin we performed two sets of interviews and rewrote parts of their codebase. The first set of interviews identified developer requirements and the second set of interviews showcased the Kotlin language and its potential use in their codebase. The results show that Kotlin can meet most of the developer requirements and that the perception of Kotlin is positive. Kotlin’s ability to be incrementally adopted was a prominent feature which reduced the inherent risks of technology adoption while providing them the ability to further evaluate the language. The expressiveness of a programming language has previously been found to be a prominent factor of language adoption. In this study, we identified the expressive nature of Kotlin as a major factor of its adoption potential.

The aim of this paper is to examine how anglicisms infiltrate into Romanian language, their influence on Romanian language and how these anglicisms are adapted to the language system. There is a comparison between adaptation of anglicisms in Czech and Romanian language. Next chapter describes also the difference between Czech and Romanian view on the definition of neologism. Examined are various cases including changing of the meaning, words that must be adopted, because they cannot be found in Romanian vocabulary or the opposite case - unnecessary anglicisms that have corresponding Romanian analogues. The paper also focuses on etymology of anglicisms, abbreviations, as well as mistakes, which may occur during adoption of English words into Romanian language. The last part examines morphology, especially the issue of gender and formation of plural forms.
