Apresento a voc\u00eas um curso completo e o mais abrangente poss\u00edvel, explicando todos os m\u00e9todos amplamente utilizados de programa\u00e7\u00e3o ass\u00edncrona, adaptadores entre eles e espa\u00e7os auxiliares. Atualmente, ele consiste em 23 palestras, 3 apresenta\u00e7\u00f5es e 28 reposit\u00f3rios com muitos exemplos de c\u00f3digo no GitHub.

Os blocos coloridos dizem respeito \u00e0 programa\u00e7\u00e3o ass\u00edncrona, enquanto os mostrados em preto e branco referem-se aos m\u00e9todos de programa\u00e7\u00e3o paralela (sem\u00e1foros, mutexes, barreiras etc.) e redes de Petri, que, assim como a programa\u00e7\u00e3o ass\u00edncrona e o modelo de atores, s\u00e3o diferentes abordagens para a realiza\u00e7\u00e3o de c\u00e1lculos paralelos (est\u00e3o no diagrama apenas para definir mais precisamente o lugar da programa\u00e7\u00e3o ass\u00edncrona). O modelo de atores est\u00e1 relacionado \u00e0 programa\u00e7\u00e3o ass\u00edncrona porque a implementa\u00e7\u00e3o de atores sem m\u00faltiplas threads tamb\u00e9m tem validade e serve para estruturar c\u00f3digo ass\u00edncrono. As linhas pontilhadas conectam eventos e a fila concorrente a callbacks porque essas abstra\u00e7\u00f5es s\u00e3o baseadas em callbacks, mas ainda assim formam abordagens qualitativamente novas.<\/p>\n<p><\/p>\n<h4 id=\"temy-lekciy\">T\u00f3picos das palestras<\/h4>\n<p><\/p>\n<p><noindex><a rel=\"nofollow\" href=\"https:\/\/youtu.be\/hY6Z6qNYzmc\">1.
