Accepted Talks


These are the talks accepted to PyTexas. They are listed alphabetically. A full schedule will be released closer to the conference.


Talk: Automating Build Tasks With Build-magic

Developers like writing software but loath building software. Amongst platform specific scripts, Makefiles, and CI pipelines, there’s no shortage of fragile, frustrating processes for building a software project. Build-magic aims to simplify builds with a declarative, repeatable tool for developers.

Speaker: Chris Morrow
Chris Morrow is a Staff Software Developer at Q2 in Austin Texas, and previously worked at Silicon Labs and Samsung. He is a Python, Go, and Elixir developer with experience in Cybersecurity, Web Development, Statistics, Data Engineering, and Data Science. Chris is also involved in mentoring and teaching programming with organizations such as Breakthrough Central Texas and Code2College. In 2018, Chris was selected as a member of the Leadership Austin Emerge class. He also participates in Austin Young Chamber and is a supporting member of the Python Software Foundation. Chris has given previous talks on SQLAlchemy at The Austin Python Meetup and An Evening of Python Coding, as well as a talk on his open source project sci-analysis at PyTexas 2019.

Talk: Choosing the Right Data Types

So often, in Python, I’ve run up against the question of what type of data structure to use to express something. Does this need a tuple, a dict, a namedtuple, a dataclass, or something else? How do you select what to use, and what are the pros and cons? Let’s explore the options!

Speaker: Josh Schneider
Josh is a test automation architect and senior developer. He's trained several junior developers, written millions of lines of code, maintained and supported that code, and pushed for process improvements around development standards, code review, design, and support. He spend a lot of time thinking about how to do things “right”, and how to teach other people. Outside of work, he's a dad of 2 nerdy kids, a trained improv comedian, movie lover, and drinker of beer and coffee.

Talk: Coding and the Mozart Effect

Most developers code to music...some are even musicians themselves. Is it possible to streamline workflow by adjusting how we listen to music and what music we listen to? Studies have shown that exposure to certain kinds of music can help to develop cognitive strength and improve performance of tasks. This talk will explore those studies and show what sort of things can be done to improve the listeners environment and help people to create better code.

Speaker: PJ Hagerty
PJ is awesome.

Talk: Event-Driven Microservices with Flask and Apache Kafka

Implementing complex systems with microservices can be a great decision, but if we’re not careful we can end up with a distributed monolith. Let’s see how to avoid that by building lightweight, loosely coupled microservices with the Flask framework and Apache Kafka.

Speaker: Dave Klein
After 28 years as a developer, architect, project manager (recovered), author, trainer, conference organizer, and homeschooling dad, Dave Klein landed his dream job as a developer advocate at Confluent. Dave is marveling in and eager to help others explore the amazing world of event streaming with Apache Kafka.

Talk: Everyday Design Patterns: Observer Pattern

The Observer Pattern enables us to design event-driven systems using loosely coupled components. In this talk, we will learn how, when, and why to use this pattern; we will explore how popular PyPI packages use the pattern; and, we will design a decorator-based Observer to process GitHub events.

Speaker: Aly Sivji
Aly Sivji is a Canadian ex-pat living in Chicago. By day, he works as a Team Lead at Narrative Science building a platform that generates narrative text using client data. By night, he co-organizes the Chicago Python Users Group (ChiPy). Aly is an active participant in the ChiPy Mentorship Program and he loves helping intermediate developers become experts. Outside of Python, Aly enjoys cycling, reading, and rewatching old TV shows.

Talk: Great Snake Variation: Programming with python-chess!

Since The Queen’s Gambit hit Netflix, the number of people playing chess online has skyrocketed. Chances are, some of them are Pythonistas! We’ll dive into python-chess: a library for representing the chess board. Along the way, I’ll show how the library also teaches useful programming concepts.

Speaker: William Horton
William Horton recently returned to chess during the pandemic, after a 15 year hiatus. On certain weekends he can be found in the local chess club trying his best, but getting beaten by elementary schoolers. By day he works as a Senior Machine Learning Engineer at Included Health.

Talk: How to Solve It: Pólya's Methods for the Pythonista

In his book “How to Solve It”, mathematician and Stanford professor George Pólya compiled some eye-opening problem-solving techniques used to solve mathematical puzzles. In my talk, I will explore how his methods can be applied to Python programming to tackle the challenges that come with it.

Speaker: Marco Tagliani
My name is Marco Tagliani and I am a Computer Science (CS) Student at Texas State University. I am originally from Buenos Aires, Argentina and I have been living in the US since 2019.

I am president of .EXE, the biggest CS club at TXST, during the Spring 2022 semester, and will be graduating in May 2023. Besides CS, I am into basketball/NBA, soccer, MMA, public speaking and performing stand-up comedy

Talk: Making Location Based Searches with Google Places API and Elasticsearch

When searching for things on the internet, there are 2 factors that determine the quality of a search result, Accuracy and Relevance. This talk walks through the process of building a search experience focused on using Elasticsearch and Google Places APIs to show results based on location.

Speaker: Jay Miller
Jay is a Developer Advocate at Elastic, based in San Diego, Ca. A multipotentialite, Jay enjoys finding unique ways to merge his fascination with productivity, automation, and development to create tools and content to serve the tech community.

Talk: Managing the Test Data Nightmare

Good test data can be a nightmare to manage! It can make-or-break testing efforts. Should we preload our databases? Should we use dynamically-generated dummy data? What about collisions? Let’s cover practical strategies for handling data both in our products and in our test cases.

Speaker: Andrew Knight
Andrew Knight is the Automation Panda and also a Developer Advocate at Applitools. He strives to help others in solving problems in software development, testing, and quality. Over the past decade, he has designed and built robust test automation projects from the ground up that can run thousands of tests continuously. He is the author of the upcoming book “The Way To Test Software” from Manning Publications, and he is also the lead developer for Boa Constrictor, the .NET Screenplay Pattern. Read his tech blog at AutomationPanda.com, and follow him on Twitter at @AutomationPanda.

Talk: Awesome Web Testing with Playwright

Everybody gets frustrated when web apps are broken, but testing them thoroughly doesn't need to be a chore. Playwright, a new open-source browser automation tool from Microsoft, makes testing web apps fun! Playwright offers a slew of nifty features like automatic waiting, mobile emulation, and network interception. Plus, with isolated browser contexts, Playwright tests can set up *much* faster than traditional Web UI tests.

Talk: Minimum Viable Security for Python Applications

Python remains a very popular programming and scripting language in the DevOps ecosystem for building CI/CD pipelines. In the same way we think about how we design and build our Python applications, we need to design, build and automate security into our applications from the ground floor.

Outside of tech, Laura runs, plays with her dogs, throws discs, and watches clouds—the real kind.

Talk: xfail and skip: What to do with tests you know will fail

What do you do with a test you know will fail? Skip it? Mark it as xfail? Or wait until the test is passing before adding it to your test suite? In this talk, I’ll explain `pytest`’s `skipif` and `xfail`, and dive into various strategies for dealing with tests that will not pass.
