October Talk: Andreas Reischuck "Using C++20 Coroutines for Asynchronous Parsers"

Hello fellow C++ learners,

for our October talk we will join the Meeting C++ Online Meetup and use Hubilo for hosting the meetup.

See: https://www.meetup.com/Meeting-Cpp-online/events/281268697/ for all the details.

Abstract:

C++20 Coroutines are one of the big new features, which are a bit hard to understand.
This talk will try to boost our understanding of coroutines.

Outline:

We start of with an introduction to parsers and why we may want an asynchronous parser.
Motivated by this, we will try to use C++20 Coroutines to implement a simple parser.
As C++ lacks library support for Coroutines, we use most of the time for this. 

The talk will have slides to introduce and visualize some concepts.
For the hands on we will do live coding.

Please pray to the live coding gods and watch out for typos.

Date: Thursday, 21. October 2021
Start: 19:00
End: 22:00
Place: Online (see https://www.meetup.com/Meeting-Cpp-online/events/281268697)

We are looking for your presentation! Please send your proposal or help us find a good talk.

Cheers!
Andreas

June Talk: Andreas Reischuck "Cross Compiling with CMake"

Hello everyone,

As nobody came up with a proper talk. I will jump in and talk about cross compiling.

Abstract:

Cross Compiling C++ projects is hard. This talk tries to shed some light on when and why you may be forced to do it. How it works with CMake using proper Toolchain files. For demonstration we will take a look at Raspberry Pi and Bluepill boards.

We will use Goto Meeting again. You will get the chance to ask your questions directly through chat or voice.

Date: Thursday, 3. June 2021
Start: 20:00
End: 21:00
Place: Online (https://www.gotomeet.me/CppUgDresden/june)

We are looking for your presentation! Please send us proposal or help us find a good talk.

Cheers!

March Talk: Roi Barkan "Argument passing, Core guidelines and concepts"

Greetings to all,

Roi will inform us with his talk about the peculiarities and pitfalls of passing arguments.

Abstract:

Core guidelines recommend passing objects to functions differently based on whether they are 'cheaply copyable'. Last year, Herb Sutter put a spotlight on the importance of simple and correct methodology for such argument passing. 

In this talk I'll remind people about subtleties of this topic and endeavor to use c++20 concepts to let the compiler assist us with the guideline.

We will use Goto Meeting again. You will get the chance to ask your questions directly through chat or voice.

Date: Thursday, 18. March 2021
Start: 19:00
End: 21:00
Place: Goto Meeting (https://www.gotomeet.me/CppUgDresden/march)

We still have open talking slots. Please contact us with your proposal.

Cheers!
Andreas
