    5/9 Research Software Engineering with Python (COMP233) - Testing with Python

    Testing your software is part of development. In this episode I talk about different types of testing, automated tests, legacy code etc. My guest is Stef Piatek from UCL who tells us how he approaches testing in his daily work.

    3/9 Research Software Engineering with Python (Comp233) - Introduction to Python

    Python is one of the most widely used programming languages in research and science. How did it come to that. And what makes Python special? It's something I discuss with my guest in this episode, Robin Wilson, who also takes us through some of the less favourable or more complex aspects of the language.

    2/9 Research Software Engineering with Python (COMP233) - Git Part 2

    In this episode we look into more essential Git commands, such as branching and merging. Branching and merging are key concepts that help you develop code or even text documents in a team. They help you maintain different versions of files and work on them independently. Another element of collaborative working is provided by GitHub: the pull request. Pull request are a great way to do code reviews, which avoids introducing bugs and also learn from each other. In my conversations Sam and Eirini talk about these key features and their experiences with it.

    10/10 C++: Wrapping it up

    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.

    9/10 - Distributed Memory and Parallel Computing

    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.
