Hello Ballerina! A programming language for the networked world

The Institute of Computer Languages of the Faculty of Informatics invites you to a guest talk by Dr. Sanjiva Weerawarana, founder of WSO2.


Ballerina is a new event-driven programming language optimized for writing networked applications and services. Ballerina learns from Java, Go, Typescript and a variety of other languages and is a complete programming system designed for the way we program today - event-driven, network-aware, security-aware, data-aware, repository-aware, concurrent, strongly typed and highly performant. Ballerina has both a C-heritage text syntax and a complete graphic syntax using a sequence diagram metaphor which promotes natural concurrent programming compared to current approaches for concurrency. Ballerina has native understanding of JSON, XML and also tabular data. Ballerina is designed to run optimally in containers and lightweight execution environments. This talk explains the concepts behind Ballerina and explains how its sequence diagram based programming model works to provide dramatic improvements in developer productivity for programs that r
 ely on a significant amount of networked interactions to achieve their objectives.
