10/10 C++: Wrapping it up

Mar 30 2025 38 mins

In this last episode of the companion podcast for the C++ course at UCL, I invited both Klaus Iglberger and Marc Hartung (Dive, Berlin) to go through some aspects of parallel computing. But also to look a little bit ahead of what's in store for C++ in future standards. And how the language may help you in your career. Links: https://www.youtube.com/watch?v=NReDubvNjRg&list=PLY_

9/10 - Distributed Memory and Parallel Computing

Mar 25 2025 38 mins

Marc Hartung and I will discuss distributed memory in parallel computing in this episode, with tools like OpenMPI. We also discuss some of the hardware aspects around HPC systems and how shared and distributed memory computations differ.

8/10 When things happen all ... in parallel

Mar 18 2025 37 mins

Parallel programming is a huge, exciting and evolving field. Together with my guest Marc Hartung from Dive in Berlin, Germany, we try to cover some aspects of it: including OpenMP, how to synchronise data etc. Links: https://en.cppreference.com/w/cpp/language/memory_model the C++ memory modelhttps://www.openmp.org OpenMP home pagehttps://www.openmp.org/resources/openmp-compilers-to

7/10 Oh please, make it faster...performance in C++

Mar 11 2025 31 mins

How can we measure the performance (run-time, memory usage etc) of our C++ code? And what does performance mean, anyway. These and other questions are the topic of this episode - with my guest Klaus Iglberger, C++ engineer, tutor and mentor.

6/10 The code you're looking for is in ... the library

Mar 04 2025 33 mins

Software libraries play a crucial role in software development, and C++ is no exception. Klaus and I walk through the different aspects of building, using and selecting libraries.

5/10 Classes and Design

Feb 18 2025 33 mins

Here we touch on some ways to build classes in C++ and how class design such as class hierarchies can help to make code more readable, more maintainable and less error prone (amongst other things). Klaus Iglberger and I also touch on design patterns and briefly what other programming paradigms exist apart from object oriented programming (OOP). Links https://medium.com/javascript-s

4/10 On Polymorphism

Feb 11 2025 26 mins

Inheritance, templates, function overloading - they all fall into the category of polymorphism in programming. My guest Klaus Iglberger and I discuss the different aspects of how this could be done with C++.

3/10 Throw, try, catch...test

Feb 04 2025 31 mins

Exceptions are essentials, as are error codes. Writes Bjarnes Stroustrup. And so on our 3rd stop through C++ I talk about what you could do when things go wrong. And what you can do to prevent errors - with testing. My guest is, again Klaus Iglberger. The sounds you're hearing are from the excellent https://sound-effects.bbcrewind.co.uk BBC sound library - free of use for non-comme

2/10 Data Types and the world of (smart) pointers

Jan 28 2025 35 mins

In the beginnings were...data and data types. Which is where we begin our journey through C++. The language provides for a range of interesting, fundamental, complex and custom types - one of which is a set of pointer types. My guest in this episode is Marc Hartung from Dive in Berlin, Germany. Links: https://en.wikipedia.org/wiki/Pointer_(computer_programming) summary of what poin

1/10 C++ - An Introduction

Jan 21 2025 38 mins

This first episode is about introducing C++, where it started, how it evolved. You will hear from 2 practitioners: Klaus Iglberger (C++ coach/trainer) and Marc Hartung (tech lead at Dive in Berlin). Here are a few links for you to follow up on: https://www.stroustrup.com The Home Page of Bjarne Stroustrup who created C++. There are plenty of links for you to followhttps://isocpp.or
