Next BeCPP UG Meeting Planned For January 29th, 2020

December 17, 2019 Marc Gregoire Events

The next meeting of the Belgian C++ Users Group is planned for Wednesday January 29th, 2020 at 18:00 at OMP.

OMP ( https://www.omp.com/ ) is sponsoring this event by providing the location, drinks and catering.

The agenda is as follows:

• 18:00: Reception with food.
• 18:30: Session 1: Coroutines in C++20 (Johan Vanslembrouck)
  A coroutine is a function that can suspend execution to be resumed later. Coroutines allow for sequential code that executes asynchronously (e.g. to handle non-blocking I/O without explicit callbacks), and also supports algorithms on lazy-computed infinite sequences and other uses. Unlike most other languages that support coroutines, C++ coroutines are open and not tied to any particular runtime or generator type and allow libraries to imbue coroutines with meaning, whereas the compiler is responsible solely for efficient transformation of a function to a state machine that is the foundation of the coroutine.
  The presentation will explain the C++ coroutines mechanism, i.e. code generated by the compiler and the code to be written by a coroutine developer. The presentation includes examples of an client-server application using Boost ASIO in combination with C++ 20 coroutines and a producer-consumer queue implemented with and without coroutines.
• 19:30: Break
• 19:45: Session 2: The evolution of the C++ Lambda (Lieven de Cock)
  Before C++11, we had to write function objects (functors) or free standing functions to pass as the callable to several algorithms (for example: for_each). The drawback was that we were introducing objects in a bigger scope than actually needed, and it can be considered as rather some boilerplate.
  With the introduction of the lambda we can write (little) callables at the moment we need them. Over the years (or better said over the new standards) the lambdas gained extra power and became more user friendly. In this talk we will have a look on the evolution of the lambda since its birth in C++11.
• 20:45: Introduction to OMP, followed by a drink.

We will be giving away 2 copies of Professional C++, the 4th Edition.

We will also give away a copy of C++17 Standard Library Quick Reference.

The event is free for everyone, but you need to register for it.

There are 100 seats available for this event.

Note: The deadline for registrations is January 26th, 2020!

Next BeCPP UG Meeting Planned For October 10th, 2019

September 1, 2019 Marc Gregoire Events

The next meeting of the Belgian C++ Users Group is planned for Thursday October 10th, 2019 at 18:00 at Brabanthal (room Luna).

think-cell ( https://www.think-cell.com/ ) is sponsoring this event by providing the location, drinks and catering.

The agenda is as follows:

• 18:00: Reception with food.
• 18:30: Session 1: C++20: What’s in it for you? (Marc Gregoire)
  With the current three-year pace of C++ releases, the next release is scheduled for 2020, C++20. This presentation gives an overview of what you can expect in the new standard. It starts with discussing the C++20 language features that will be added by the C++20 standard, such as concepts, coroutines, templated lambdas, the spaceship operator, pack expansion in lambda captures, string literals as template parameters, extra initializer for range-based for loop, modules, and more. Next, we’ll delve into the new Standard Library features, such as ranges, std::span, atomic smart pointers, and more. Depending on the outcome of the next C++ Standard Committee meeting, the list of new features might include improved futures, task blocks, and text formatting. If you want a concise overview of what the C++20 standard will offer, then this presentation is for you.
• 19:30: Break
• 19:45: Session 2: From Iterators To Ranges — The Upcoming Evolution Of the Standard Library (Arno Schödl)
  Pairs of iterators are ubiquitous throughout the C++ library. It is generally accepted that combining such a pair into a single entity usually termed Range delivers more concise and readable code. Defining the precise semantics of such Range concept proves surprisingly tricky, however. Theoretical considerations conflict with practical ones. Some design goals are mutually incompatible altogether.

CluePoints ( https://cluepoints.com/ ) is sponsoring this event by providing the location, drinks and catering.

The agenda is as follows:

• 18:00: Sandwiches.
• 18:30: Session 1: What’s new in Visual C++ 2019? (Marc Gregoire)

• 19:30: Break
• 19:45: Session 2: Statistical Scientific programming: challenges in converting R to C++ (Olivia Quinet)
  Scientific programming is in itself a challenge due to several concomitant issues and requirements including low response time, low memory usage, minimizing numerical errors, error propagation.
  R is a programming language for statistical computation providing a wide set of packages for linear and non linear modeling, statistical tests, …
  This talk will focus on the different Object-Oriented strategies implemented to overcome those challenges, speed up the computation while reducing the memory footprint.
