We now can write coroutines that run on executor threads and produce values. Let’s see if we can make working with them a little bit more pleasant. We will also implement await_transform to allow co_awaiting a different type....

PHP is back and is faster and more lightweight than ever. The world of web technology is seamlessly evolving, and PHP 7's simplicity and prowess addresses the requirements of current and future web and mobile application...

Thread pool is a collection of threads that execute incoming jobs or tasks. Clients push tasks on the queue, and threads pick them one at a time. This provides an abstraction for background tasks. In addition, there is a single...

Guidelines are, first and foremost, a collection of rules. If the rules are not enforced, they will not be followed. The guidelines are intended as specification for static code analysis tools. In this video we will learn how to...

Mutex is an object that lets us protect a resource from being accessed from multiple threads simultaneously. Mutex is one of many synchronization primitives. It’s easy to use, but there are a few caveats.

• Example of a mutex:...

Search is the most common operation we perform on data. There are three common types of search: Linear, sorted (binary), and by hash.

Coroutine is a function whose execution can be suspended and resumed. Suspension saves the state of the function, then the caller can execute as if the function has returned. Resumption loads the saved state back and continues...

👉 Learn how to find the contrapositive of a statement. The contrapositive of a statement is the switching of the hypothesis and the conclusion of a conditional statement and negating both. If the hypothesis of a statement is represented...

Fork/Join builds on top of continuation. The idea is that not one, but multiple parallel tasks can consume results of the previous one. And after those tasks are finished, another task aggregates the results. In this video we will...

Continuation is when an asynchronous task consumes results of the previous one. In this video we will implement and use such pattern. Additionally, we will see how to handle exceptions and propagate them to the caller of a...

We had implemented a concurrent tasks framework in Section 9. Back then we observed that threads had to wait on each other, which reduces concurrency. In this section, we will create a tasks framework that uses coroutines to achieve...

Copy creates a duplicate of an object. Move transfers ownership of resources. We can control the behaviors of copy and move by writing copy and move constructors (and operators).

• Rules for implementing copy constructors and...

Abstraction hides complexity and preserves only the information that is relevant in the context. We create leaky abstractions when we fail to hide information that is irrelevant. This video is an exercise in creating an...

Templates are one of the distinctive features of C++, and arguably the most complex one. When used correctly, templates make your code less complicated, and this is not a contradiction.

C++ does not specify semantics for coroutines. Instead, the language provides some low-level constructs. The promise is an interface for a coroutine’s state machine, and there are also a few primitives for suspending and resuming a...

This clip is from the chapter "Exploring Data" of the series "Python for Data Analysis: Step-By-Step with Projects".This section introduces you to exploring data.

In this video, we will use promise, future, and a lambda to create a version of std::async that uses our thread pool. Then we will learn some design patterns for efficient concurrent programming.
