Last fall I was teaching INF214 “Concurrent Programming” at University of Bergen (Norway). The course is both for Bachelor- and Master-level students, and was taught in a hybrid mode (online and on-campus), with 120+ students signed up. My implementation of the course featured short pre-recorded videos, weekly obligatory quizzes and regular classes. — Videos There are 70 videos altogether, with duration of 5 to 10 minutes on average. Each video is devoted to a particular topic, e.g., “tie-breaker algorithm”, or “The Sleeping Barber Problem”.

Based on book Kotlin in Action by Dmitry Jemerov and Svetlana Isakova, and Kotlin Reference.

And the same ABC formatted as slides goes here.

Language Integrated Query (LINQ) is an extension to Microsoft .NET languages that provides query expressions that can be used to extract and process data from collections (for example, arrays, lists, dictionaries). Concrete syntax of query expressions resembles SQL statements: IEnumerable<Person> query; query = from p in Persons where p.age …

When syntax of programming languages is communicated, context-free grammars are a lingua franca. They define structure of syntax, but cannot express static semantics. This post gives an overview of other successful grammatical models (attribute, two-level, parsing expression, conjunctive, Boolean grammars) in relation to defining programming languages. Attempts to specify Algol After Chomsky introduced phrase…

I am starting a series of posts explaining JetBrains MPS, a powerful tool to define and implement domain-specific languages and IDEs for them. …

I present here a small bibliography of papers on programming languages from the 1970’s. I have personally considered these papers interesting in my research on the syntax of programming languages. I give here short annotations and comments (adapted to modern’s day notions) on some of these papers. ALGOL 68 might-have-beens, by S. G. van der Meulen (1977) About “natural, easy…

After teaching a university course on domain-specific languages (http://dsl-course.org), I found myself puzzled with two questions: how to get more people interested in the rapidly developing field of DSLs and language-oriented programming, and how to better explain all intricacies of language implementation? Let’s focus on the second point. Who would…
