I understand that Task.Run() is required since if we want to use await directly , then the calling method will need to be made Async and will affect the calling places. Here is the sample code which has async await within Task.Run() . The full sample is provided here : https://msdn.microsoft.com/en-us/library/hh228607(v=vs.110).aspx Task.Run(async () => { await new WebClient()

Currently, each consumer thread waits on a boost::condition_variable - when a producer adds something to the queue, it calls notify_one / notify_all to notify all the consumers. Now what happens when you (potentially) have 1k+ consumers? Threads won't scale! I decided to use boost::asio , but then I ran into the fact that it doesn't have condition variables. And then async_condition_variable was born: class async_condition

So, for example, we have this code: await someCall (); await anotherCall (); Do I understand it correctly that anotherCall() will be called only when someCall() is completed? What is the most elegant way of calling them in parallel? I want to use it in Node, so maybe there's a solution with async library? EDIT: I'm not satisfied with

The exact number of drop-down menus is unknown and created dynamically. Example: {{nr.name}} {{item.name}} Submit The whole things fails at Dropdown[nr.id] which does not seem to work with async pipe. I played around a bit: {{myAsyncObject | async}} //works {{myAsyncObject['prop1'] | async}} //fails silently {{myAsyncObject['prop1']['prop2'] | async}} // EXCEPTION: TypeError: Cannot read property 'prop2

I have been unsuccessful at achieving the "parallel" part thus far. Here is what I tried at first: import 'dart:io'; main() { HttpServer.bind(InternetAddress.ANY_IP_V4, 8080).then((HttpServer server) { server.listen((HttpRequest request) { Stopwatch stopwatch = new Stopwatch(); stopwatch.start(); while (stopwatch.elapsedMilliseconds < 1000) { /* do nothing */ } request.response.statusCode = HttpStatus.OK; request.response.write(stopwatch

I have used IP aliasing technique to increase number of clients and severs using just single client/server machine. Upto now I have created 50 IP alias on my client machine and 10 IP alias on my server machine. I am also using multiprocessing module to generate traffic concurrently from all 50 clients to all 10 servers. I have also developed few profiles(1kb,10kb

At some level that must be what is going on since you can wrap normal async methods in a Task of T with Task.FromAsync but

Like map() , return values must be returned in the same order as iterable . I tried this (I need requests because of legacy auth requirements): import requests def get(i): r = requests.get('https:/

I used a lot of async/await for file IO, dialogs, network, etc… What happens when the app is paused/suspended during an await call? Under Windows and iOS there are two possibilities: the app is resumed later, as if nothing had happened the app is terminated if memory is low. In both cases, there is no memoy leak, there are no changes in control flow. However, under Android, an Activity can be destroyed and recreated while the process stays alive. In my
