Learn how to visualize algorithms with LEDs, dodge bugs with MyPy, and more

On April May 9th, join ~150 devs at SF Python's presentation night to hear a few short talks and one more PyCon talks from local speakers :) Our generous sponsor Yelp will also provide pizza and beer for the evening.

Please register via (https://ti.to/sf-python/Visualizing-Algorithms-with-Python-and-Programmable-LEDs), not Meetup RSVP. Those without a registration from by Wed 9a will need to wait till 6:45p to enter and risk not having any pizza left.

If you'd like to make a 1-2 minutes announcement at the opening of this meetup and contribute back to the community, considering stepping up as a video sponsor. You will help fulfill the #1 requests of those who can't attend the meetup and enjoy additional sponsor perks. More info here: (https://bitly.com/sfpthonvideo)

If you'd like to give a 5 mins lightning talk or 10-15 mins short talk at upcoming meetups, please submit your talk idea here (https://goo.gl/forms/ICpqIMunLo3ZgsrC3).

• Jardin, the friendly and lightweight ORM for Python, by Emmanuel Turlay
• Deploying SciKit Learn Models in Flask, by Ben Aaron
• "Moving a Python Colossus at Pinterest, Slowly", by Jordan Adler

Short Talk: Making the most out of Mypy by Phil Nachum

Mypy is great for avoiding bugs, but with tweaks to how we model our data, we can often produce more reliable and clearer code. The talk covers some of these techniques.

Speaker Bio
I'm a software engineer at Freenome, a biotech startup on a mission to cure cancer. I'm new to Python, but I'm a big fan of typed functional programming and bringing ideas from that world into Python.

Main Talk: Visualizing Algorithms with Python and Programmable LEDs by Christopher Beacham / Lady Red

Recently, a new LED strip specification, APA102, has been released which allows these strips to be driven by a general purpose CPU instead of a dedicated microcontroller. This allows us the luxury of controlling them with Python!

I'll teach you about how to get the hardware, how to think about programming for lights and how to build anything from a psychedelic art installation to home lighting to an educational tool.

Programming with lights is awesome because you can SEE bugs with your eyes. I think the use of these LED's have great potential as a teaching tool because of the immediacy of the feedback.

LIVE hardware demos! See Quicksort in brilliant colors!
