On March 14, join ~150 devs at SF Python's presentation night and learn more about new language features and a new language. :) Our generous sponsor Yelp will also provide pizza and beer for the evening.

If you'd like to give a 5 mins lightning talk or 10-15 mins short talk at this or upcoming meetups, please submit your talk idea here.

PROGRAM

Lightning talks (5m)

• Lessons learned from migrating to Python 3 at CMB, by Ann Paul
• Narrative Logging with Eliot, by Stephan Fitzpatrick
• Packaging a flask + gunicorn app with Docker and deploying on Hasura, by Tanmai Gopal
• importlib.resources, by Barry Warsaw

Short talk (15m + Q&A)

Nim for Python programmers, by Abhishek Kapatkar

Ever wondered if there existed a language as expressive as Python and as efficient as C/C++? Look no further then. Nim is a statically typed, compiled language with a focus on efficiency. It is versatile and borrows much of its constructs and standard library design from Python https://nim-lang.org

Bio: Abhishek Kapatkar works at Netflix on Machine learning infrastructure team, whose mission is to make using data easy and efficient. He and his team are responsible for envisioning how the data platform allows data scientists to make Netflix's service even better. He enjoys product development, programming language design, and is passionate about the usage of technology for the social good and currently serves as a San Francisco chapter leader for Datakind.org.

Main talk (~40 mins + Q&A)

Trio: Async concurrency for mere mortals, by Nathan Smith

Concurrent programs are super useful: think of web apps juggling lots of simultaneous downloads and websocket connections, chatbots tracking multiple concurrent conversations, or web spiders fetching pages in parallel. But writing concurrent programs is complicated, intimidating to newcomers, and often challenging even for experts.

Does it have to be? Python is famous for being simple and straightforward; can Python make concurrent programming simple and straightforward too? I think so. By carefully analyzing usability pitfalls in other libraries, and taking advantage of new Python 3 features, I've come up with a new set of primitives that make it dramatically easier to write correct concurrent programs, and implemented them in a new library called Trio. In this talk, I'll describe these primitives, and demonstrate how to use them to implement a basic algorithm for speeding up

Bio: Nathaniel J. Smith is a cognitive scientist and open-source developer, currently at the UC Berkeley Institute for Data Science. He's a core developer on NumPy and CPython, brought the '@' operator to Python, co-designed matplotlib's "viridis" colormap, instigated the creation of "manylinux" wheels, and writes too many PEPs. He won't be talking about any of that.
