  4. Events flow • Each client hangs on its socket and listens to it; • If a message arrives,the client creates Eventobject and passes itto the EventsQueue; • Server’s auxiliary thread, processEvent, getsthe Event and acts accordingly, e.g. sends message for all on the server.

  5. Clients • Main client is written on c++ programming language and uses FLTK toolkit as GUI framework; • Also there were writtena pair of bots using python3: • the weather bot uses openweather API, JSON; • the calc bot useswolfram API, XML.
