Server.js: A simple Node.js HTTP server that receives a request, and returns a response ~5s after. To understand how coroutines and non-blocking I/O work together, here's a practical example: Coroutines simply provide an easier programming model consisting of suspending functions instead of hard-to-read CompletableFuture continuations in Java, and structured concurrency among other concepts.

Add the port configuration to the advanced configuration snippet, for example:. Non-blocking I/O is not a feature of coroutines though. Open a non-ephemeral port (such as 9011) in the firewall. For example, by default a highly concurrent program such as a web server running in a computer with 2 CPUs would have its compute capacity degraded by 50% while a thread blocks waiting on I/O to complete in a coroutine. This is why the default coroutine dispatcher – Dispatchers.Default – has a total of max(2, num_of_cpus) threads to execute dispatched coroutines. His objective is the participation and examination of culinary cultures from around the world as well as in exploring aspects of social identity, rituals and ways of preserving and memory.Coroutines are designed to contain non-blocking (i.e. Since 1996, his FoodCulturaMuseum has ed an open work on a global scale, with multiple initiatives - such as the large pavilion for the World Expo 2000 in Hannover - through countless devices that distort the museographical archetypes. The concept of a piece as a process is one of this artist’s hallmarks, as in Honeymoon Project1986-1992 that symbolises the marriage between the Statue of Liberty in New York and the Christopher Columbus monument at the port of Barcelona, with which he explores the concepts of conquest, freedom and cultural exchanges between Europe and America.įood is a semiotic system for Miralda, like when he produces the flags of the major powers with coloured rice, which rots and transform in such a way that the flags acquire new colours and therefore new meanings. Miralda moves to New York in 1972, where he completes several projects that dialogue with the fusion of cultures and its popular manifestations in large celebrations. In 1969 he organises the first of these installations at the American Centre in Paris, to be followed by others such as Fest fur Leda (Feast for Leda), for Documenta 6, Kassel in 1977. It is in the Paris of the Sixties where the artist is first to use food as an anthropological, cultural and political reference. At this time soldiers invade the entirety of his work: photographs, frottages-collages, posters, furniture, the streets of Paris or the cinema, like in Paris. The exhibition covers the different periods of a career that begins in the Spain of the Sixties with distinctly pacifist works.
