Belgian C++ UG

Next BeCPP UG Meeting Planned For March 30th, 2020

March 10, 2020 Marc Gregoire Events

This event is cancelled in light of the current state of the Covid-19 outbreak.
We will try to get our two international speakers, Greg and DeWang, back to Belgium at a future event.

The next meeting of the Belgian C++ Users Group is planned for Monday March 30th, 2020 at 18:00 at KU Leuven Department of Computer Science. The welcoming and reception takes place at Foyer Computerwetenschappen (room 00.191), while the sessions will take place in Auditorium Erik Duval (room 00.225)

Dekimo ( https://www.dekimo.com/ ) and KU Leuven Department of Computer Science ( https://wms.cs.kuleuven.be/cs/english ) are sponsoring this event by providing the location, drinks and catering.

This time we have two international speakers:

Greg Law: The co-founder and CTO of Undo.
DeWang Li: Software Integrity Architect @ Synopsys Software Integrity Group.

The agenda is as follows:

18:00: Reception with food.
18:30: Session 1: Amazing tricks with the GDB debugger (Greg Law)
If you’re writing C++ for anything other than Windows, chances are that you occasionally break out GDB. This session presents some of the lesser known features of GDB that can change the way you debug. GDB has come a long way in the last few years and now does so much more than break, print, step and continue. Reversible debugging; Non-Stop Mode; Multi-process Debugging; and Dynamic Printf are but some of its best features, and its built-in Python scripting is particularly powerful. Join Undo co-founder and CEO, Greg Law, as he takes you through a series of demos to show some amazing tricks with GDB and some of its powerful new (and not-so-new) features that you may not have heard of.
19:15: Session 2: Static analysis and Coverity (DeWang Li)
The C/C++ code you create plays such a pivotal role on our planet, and as such, companies are investing heavily into ensuring they are safe and robust. One of the disciplines they invest in to ensure that is static analysis. DeWang will explain the fundamentals of static analysis, and using his favorite product, Coverity, demonstrate some of its capabilities. He will share stories from working with some of the top Silicon Valley companies and how they apply Coverity.
19:55: Break
20:10: Session 3: Interactive discussion on pointers (Lieven de Cock)
Let’s have an exchange of thoughts on the topic of pointers: raw pointers, smart pointers, std/boost::optional and std::reference_wrapper.
How to express intent and how to avoid checking things that might not be needed to check?
We will present some use cases to get the discussion going. This is an interactive session, so start thinking about questions or opinions you might have.
20:50: Introduction to Dekimo, and KU Leuven Department of Computer Science, followed by a drink.

We will 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 March 26th, 2020!

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.

C/C++ Challenge Belgium & The Netherlands 2019 by Dekimo

October 15, 2019 Marc Gregoire Events

The Dekimo C/C++ Challenge is a contest designed to inspire creative and enthusiastic C/C++ Students & Professionals located in Belgium and The Netherlands. It is also a unique opportunity to fight an epic battle between Belgium and The Netherlands in the field of C/C++ programming: it’s not about the best soccer team, it’s all about the best software engineers!!

The first round is played online. The students and the professionals will compete in separate leagues so that everyone gets a fair chance in competing to be crowned as C/C++ Champion.

Registration is free and open during the entire duration of the Challenge.

At the end of the online round, the top 30 players will be invited for the finals.

The 15 best Professionals
The 15 best Students

The finals are intended to determine the top player in each league. Of course, there are cool prizes to be won that all have to do with smart electronics (a nifty drone for the winner in each league, and a nice voucher for the runners-up!)

If you are interested, visit the official website for more information.

Next BeCPP UG Meeting Planned For October 10th, 2019

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.

19:45: 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.
20:45: Introduction to think-cell, 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.
