"Static typing: beyond the basics of def foo(x: int) -str: [EuroPython 2019 - Talk - 2019-07-10 - Boston] [Basel, CH] By Vita Smid The Python community has been warming up to static typing for a few years now. You may have seen talks that did a great job of introducing the basic concepts, mypy, and high-level strategies to cover existing code bases. We need to go deeper. Let’s talk about the challenges you inevitably encounter when you try to type-check a large code base. One full of many moving parts, complex architectures, metaprogramming tricks, and interfaces with a dozen other packages. Static type checking is very powerful – when you use it to maximum advantage and explain your code to the typechecker accurately. We will cover a few tools at your disposal: generics, signature overloads, protocols, custom mypy plug-ins, and more. There is more than just tools, though. Behind them all are universal concepts valid in any language. I hope to convince you that thinking in terms of the type system helps you write better code… License: This video is licensed under the CC BY-NC-SA 3.0 license: https://creativecommons.org/licenses/by-nc-sa/3.0/ Please see our speaker release agreement for details: https://ep2019.europython.eu/events/speaker-release-agreement/

"Are women underrepresented in the High Performance Computing (HPC) community? [EuroPython 2019 - Keynote - 2019-07-11 - MongoDB] [Basel, CH] By Athina Frantzana This study is the first attempt to understand the current gender demographics of the HPC community, and identify potential reasons and ways to tackle the gender imbalance. By listening to the people who constitute the community, the study offers a guideline on what the HPC community should focus on in order to become more attractive, accessible and useful to everyone.

"Testing Microservices: fast and with confidence [EuroPython 2019 - Talk - 2019-07-11 - Shanghai] [Basel, CH] By Stephan Jaensch A main advantage of microservices is improved developer velocity. One roadblock to achieving it is giving developers the confidence that their changes are correct and safe, which is a challenging problem in such a distributed architecture. Typical approaches involve relying on automated end-to-end testing, which is costly to set up, develop tests for and run. In this talk I will explore an approach to testing that does not require the presence of any external dependencies (not even ""fake"" or ""test double"" implementations of them), but provides many of the benefits of an end-to-end test. Come by to learn about how we can use a downstream service's API specification to make sure the system under test interacts with it in the correct way (""contract testing"") - a key ingredient missing from most unit or integration test setups. We'll then go even further to cover testing scenarios that previously could only be covered with end-to-end tests: how to maintain and validate state of your downstream dependencies.

"The state of Machine Learning Operations in 2019 [EuroPython 2019 - Talk - 2019-07-11 - Singapore [PyData track] [Basel, CH] By Alejandro Saucedo This talk will provide an overview of the key challenges and trends in the productization of machine learning systems, including concepts such as reproducibility, explainability and orchestration. The talk will also provide a high level overview of several key open source tools and frameworks available to tackle these issues, which have been identifyed putting together the Awesome Machine Learning Operations list (https://github.com/EthicalML/awesome-machine-learning-operations). The key concepts that will be covered are: * Reproducibility * Explainability * Orchestration of models The reproducibility piece will cover key motivations as well as practical requirements for model versioning, together with tools that allow data scientists to achieve version control of model+config+data to ensure full model lineage. The explainability piece will contain a high level overview of why this has become an important topic in machine learning, including the high profile incidents that tech companies have experienced where undesired biases have slipped into data. This will also include a high level overview of some of the tools available. Finally, the orchestration piece will cover some of the fundamental challenges with large scale serving of models, together with some of the key tools that are available to ensure this challenge can be tackled.

Python and GraphQL [EuroPython 2018 - Talk - 2018-07-27 - Lammermuir] [Edinburgh, UK] By Alec MacQueen GraphQL query language is gaining popularity and seeing more adoption. This is mainly due to the efficiency with which consumers can get their data, the ease with which you can document and explore your API and the powerful tooling that has been built around the query language. This talk is for novices and experts of GraphQL alike and aims to cover the basics of the query language, how to implement it using Flask and SQLAlchemy and to take a deeper dive into how Python’s type-hinting can be used to generate your GraphQL schema. I’ll also be talking about some of the tooling that can be used to provide consumers and developers working on your API with a great development experience. Next I'll cover some ways you can use these tools to empower your development process and get you developing 'API First'. To get the most out of this talk you should have a general understanding of APIs, Python frameworks and Python ORMs. However, my aim is to make it as accessible as possible for developers of all experience levels.

Domain-Driven Design Patterns in Python [EuroPython 2018 - Talk - 2018-07-27 - Kilsyth] [Edinburgh, UK] By Robert Smallshire Domain-Driven Design (DDD) is an approach to software development that emphasises high-fidelity modelling of the problem domain, and which uses a software implementation of the domain model as a foundation for system design. This approach helps organize and minimize the essential complexity of your software. DDD has been used with success within the traditional enterprise programming ecosystems of Java and .NET, but has seen only limited adoption in the Python community. In this talk we introduce Python programmers to the core tactical patterns of DDD and show how they can be realised in idiomatic Python, freeing the most valuable parts of your system – the domain model – from onerous dependencies on particular databases or application frameworks. In this talk we share what we've learned from applying DDD in Python to large projects.

The Challenges of Maintaining a Popular Open-Source Project [EuroPython 2018 - Talk - 2018-07-27 - Kilsyth] [Edinburgh, UK] By Raphael Pierzina In this talk, I will give an insight into what it means to maintain a popular project for me personally, what it involves and what we as a community can do to help out and finally why I think it's an important discussion to have. Cookiecutter is a command-line utility that creates projects from templates. It is free and open-source software distributed under the terms of a permissive BSD-3 license. With around 180 individual contributors, more than 1000 public templates on GitHub alone, and multiple talks at conferences, it is fair to say that there is a small community around it. But who are the people behind the project and what is it that they are doing? It's been three years since I was granted the commit bit by the core team. I have learned a lot about FOSS communities and also about myself. At times I struggle with balancing my day job as a full-time Software Engineer and maintaining Cookiecutter and other FOSS projects in my spare time. By now I'm OK with not responding to issues immediately and closing pull requests. However it took me quite a while to get to this point. Maintaining FOSS projects can be incredibly rewarding and fun, but it can also be quite frustrating. It involves so much more than writing code or merging PRs, and yet sometimes it feels like that's what most people think. The goal of this talk is to start a conversation around this topic and hear what other EuroPython attendees think about it and their challenges as contributors or maintainers.
