Packaging in Python is one place where the common adage "There should be one and preferably only one obvious way to do it" doesn't seem to apply. There are a lot of choices to make when publishing python code. What is absolutely essential and what is optional?

Paralyzed by the number of choices needed to publish python package? Find out what you need to know for packaging in 2022

The Python packaging landscape is experiencing a renaissance but along with new standards and new tools comes a lot of new choices when publishing. setup.cfg or pyproject.toml? Do you need a setup.py instead or in addition? There can be a lot of confusion but understanding modern trends can make sharing your code easier than ever before.

Write Docs Devs Love: Ten Tricks To Level Up Your Tech Writing

Every phase across the end-to-end machine learning lifecycle exposes a plethora of security risks that often go unnoticed by machine learning practitioners. In this talk we uncover the most critical (and common) security risks in the machine learning lifecycle, covering in-depth concepts as well as practical examples of ways in which these can be exploited as well as resolved and mitigated (analogous to the OWASP Top 10 industry standard). 

Throughout the talk we will be using a hands on example, where we will be training, packaging and deploying a model from scratch, outlining key risk areas for each step together with tools and practices that can be used to mitigate these risks. By the end of this talk, machine learning practitioners will have a robust intuition of the importance of security best practices throughout the machine learning lifecycle, together with tools and frameworks that can help mitigate undesirable outcomes due to security flaws.

Secure Python ML: The Major Security Flaws in the ML Lifecycle (and how to avoid them)

MicroPython - a reimplementation of Python for microcontrollers - is nine years old. How can you find your way in a jungle of tiny chips, circuits, and jumper wires? In this session, we will run through a brief introduction to the world of MicroPython. Beyond the basics, we will explore the projects, tools, and the  community that helped your intrepid speaker to get started as a newcomer.

Run Python everywhere! Exploring the world of MicroPython: microcontrollers, LEGO bricks, and blinky LEDs!

MicroPython is a reimplementation of Python for microcontrollers, originally developed as a result of a Kickstarter campaign. Today, it is an approachable way into programming for many young people, via boards like the Raspberry Pi Pico, the BBC micro:bit and the CodeBug - you can even run it on LEGO bricks! It is increasingly being used in commercial fields as well. MicroPython is helping Python to get into even more places, and making programmers more efficient as it does so.

Andy Piper wanted to learn more, so he spent some time travelling and adventuring on the internet, to discover the community and projects around MicroPython.

The goal of this session is to briefly explain the What, Why and How of MicroPython. There *will* be circuit boards, and discussion of microcontrollers! We will take a look at examples, from established development boards to brand new ones. We will also acknowledge how MicroPython has been built upon, to enable different ways of working (with CircuitPython), and LEGO robots (via PyBricks). 

Finally, and most importantly, you'll get a good sense of the places you can find and learn from the MicroPython community, and how you can get involved and contribute!

Try Something Different: Explore MicroPython! (a rough guide for newcomers)

Distributing Python GUI applications to end users is a challenge: will they need to install Python? If so, which version? If not, how do they install the application? From a random ZIP file? How native does the process feel? Will their system trust your code? For a fluid experience, it needs to be signed and (on macOS) notarized beforehand.

Welcome to [`pup`](https://pypi.org/project/pup/), the tool that the [Mu Editor](https://codewith.mu/) development team has created to package and distribute it in platform-native formats to Windows and macOS users around the world.

In this session I will show how `pup` can be used to package GUI Applications for distribution: natively on Windows and macOS, and in early stages of development for distribution-agnostic Linux artifacts. In short, if it's `pip`-installable it is `pup`-packageable!

I will then describe the way `pup` works (and how it differs from comparable tools) leading on to a call-for-action moment, where I'll share its current state of development, what's good, what's bad, and where I'd like it to be headed to.

I'll wrap up the talk with a set of future-looking thoughts that `pup` has helped identify not only on the specifics of CPython's distribution, but also on the Python ecosystem as whole.

Like many companies with multi-million-line Python codebases, Carta has struggled to adopt best practices like Black formatting and type annotation. The extra work needed to do the right thing competes with the almost overwhelming need for new development, and unclear code ownership and lack of insight into the size and scope of type problems add to the burden. We’ve greatly mitigated these problems by building an automated refactoring pipeline that applies Black formatting and backfills missing types via incremental Github pull requests. Our refactor applications use LibCST and MonkeyType to modify the Python syntax tree and use GitPython/PyGithub to create and manage pull requests. It divides changes into small, easily reviewed pull requests and assigns appropriate code owners to review them. After creating and merging more than 3,000 pull requests, we have fully converted our large codebase to Black format and have added type annotations to more than 50,000 functions. In this talk, you’ll learn to use LibCST to build automated refactoring tools that fix general Python code quality issues at scale and how to use GitPython/PyGithub to automate the code review process.

In the career of many developers, there comes the point of deciding "what next?". The typical two choices are- to stay on the technical path and pursue the way of a software architect or take a leap of faith and jump to a people management role. In my talk, I'll show you the pros, cons, and challenges of pursuing the latter.

Dr. Jekyll & Mr. Hyde - transition from developer to manager without going crazy or becoming evil

You've been a developer for a couple of years already. Your journey started as an intern/junior-level position where you were learning to code; then, going through mid and senior positions, you were offered the team lead or even engineering manager role. At this moment, you have plenty of questions and doubts. How to answer them to make sure you make a good decision? How to prepare for the new role if you want to take it? I'll help you answer these questions and prepare for your future role.
