More coroutines.
Automatically Resuming a Job with Coroutines on a Separate Thread
by Rainer Grimm
From the article:
In my last post "Starting Jobs with Coroutines", I applied co_await to start a job. In this post, I improve the workflow and automatically resume a job if necessary. In my final step, I resume the job on a separate thread...

C++ coroutines: The lifetime of objects involved in the coroutine function
by Raymond Chen
From the article:
We finally hooked up the last missing piece of our coroutine promise implementation. Before we can look at the tradeoffs we’ve made, let’s step back and follow the lifetime of the various objects involved in the coroutine function.

C++ coroutines: Managing the reference count of the coroutine state
by Raymond Chen
From the article:
Last time, we hooked up the co_await of the simple_task and we had a brief glimpse into the the management of the reference count on the promise (and therefore also the coroutine state). Today we’ll fill in the rest of the story...

C++ coroutines: Awaiting the simple_task
by Raymond Chen
From the article:
Last time, we accepted the parameter passed to co_return and stored it into our promise. This time, we’ll deal with the consumption side and wait for the answer to appear...

C++ coroutines: Accepting types via return_void and return_value
by Raymond Chen
From the article:
Last time, we built the result holder for our simple_task coroutine and showed how to move values into the holder and move them back out.
So now we’re actually going to move them in...

C++ Lambda Story in Print
by Bartlomiej Filipek
About the book
I packed my knowledge about lambdas into a beautiful ebook, with lots of examples and additional descriptions. And just as with my book about C++17, I made it available at Leanpub. The platform makes it easy for me to publish new updates, and everyone who has the book can immediately access the latest changes (at no charge). Also, the platform allows you to read it as PDF and Epub, Mobi or Online.

Hightlighting a less known C++20 feature:
Mathematical constants in C++20
by Jens Weller
From the article:
When I researched the library and language features of C++20 for the Meeting C++ Community survey, this feature catched my eye.
And I thought its such a nice small feature, I should mention it on the blog. As all other C++20 blog posts right now seem to be about coroutines. It also is a nice follow up on an old blog of mine: C++ & π, where I showed the various ways of obtaining pi for C++ in 2013...

C++ coroutines: Building a result holder for movable types
by Raymond Chen
From the article:
One of the pieces we need for the simple_promise we use to construct a coroutine is what we have been calling the “result holder”. This is basically a variant that starts out empty, and can atomically transition to holding either the result of a successful coroutine, an exception pointer for a failed coroutine...
