The preceding code demonstrates a bad practice: constructing synchronous code to perform asynchronous operations. As written, this code blocks the thread executing it from doing any other work. It won't be inte
Now the bad news. For BeginWrite not to use another thread from the pool, the isAsync parameter to FileStream's constructor must be set to true, as I've done in my example. However, a little-known consequence of using FileStream.BeginWrite to initiate an asynchronous write is that there...
You might notice the ViewModel type is called BadMainViewModelA. This is because I’m going to first look at a couple of common mistakes relating to ViewModels. One common mistake is to synchronously block on the operation, like so: XMLCopy public class BadMainViewModelA { public BadMainVie...

A bad pointer or overflow in one thread can cause crashes in other threads that may be very difficult to trace. RTOS responsibilities These are: • pass messages between tasks, • create and destroy threads or tasks, • prioritize and time allocate task execution, • coordinate multi...

attitude towards Python 3.5's new async/await syntax. But before we talk about the best way to use async/await, lets digress to talk about why async/await even matters. ...Actually I'm going to digress even more then that. Let's start by talking about what programming languages are ...
any errors and the return value of the passed function (if you need it). If you don't provide a callback and there is an error, run will throw the error which will produce an uncaught exception. That may be okay for quick and dirty work but is probably a bad idea in production ...
