If you could have anyone in the world make a presentation to TriPython about the Python topic of your dreams, what would it be?

Because if we're going to meet virtually, the presenter could be anybody anywhere.

Would anyone be interested in seeing a presentation on the heapq.merge method?? I thought it had some limitations that were 'show stoppers' for a problem I was solving, but I think I can tell a story of overcoming those limitations.

I would love to see Josh Dillon from the Google Tensorflow Probability team
give a talk on Tensorflow Probability--why they built the package and where
it's headed next.

This is a save the date for next Thursday October 29th 6pm, when we will be
having our second-ever online TriPython meetup. Consider this a teaser
trailer. More details and links will be provided next week. :)

This month Mark Hutchinson will be the featured presenter, followed by
impromptu lightning talks. Mark will be presenting some very interesting
work that will take us through branches, heaps, and stacks, showing how to
efficiently match data without taking up too much CPU cycles or RAM. It is
entitled 'heapq is neither Heap nor Stack'.

 Ahead
Message-ID: <2790A10B-055C-46DA-B0AD-9002BDC9B512@unc.edu>

https://www.meetup.com/tripython/events/274045807/

Thursday, October 29, 2020
6:00 PM to 8:00 PM EDT

This will be our second-ever online bimonthly TriPython meeting. It will consist of a featured presentation by our very own Mark Hutchinson. His presentation 'heapq is neither Heap nor Stack' will focus on a recent intriguing data matching problem that had to be solved using as little CPU and memory as possible. This will be followed by impromptu lightning talks. The meeting will be conducted via Zoom. Please RSVP for this event on meetup.com to view the Zoom link.

Title(s):
Merging Traffic Ahead
Merge is not Zip
Hey, merge(), your assumptions annoy me
heapq is neither Heap nor Stack

Abstract:
I faced a data matching problem where the runtime environment was to consume as little CPU and memory as possible. In other words, be inconspicuous and unobtrusive.  The data was in two rather large files, so in-memory processing was out.

I looked at the heapq.merge() method, but it only works for ascending data. This presentation will follow my journey to be able to use heapq.merge() in ways that I didn't think possible. I was also able to expand the flexibility of the sort/sorted function.

Featured Libraries:
heapq
itertools
pandas
pandas.DataFrame.sort_values
pandas.DataFrame.drop_duplicates
pandas.DataFrame.to_csv
Featured Data Structures:
Classes
Lists

Performance Topics:
Space vs. time trade-off
I/O vs. memory trade-off
Measuring the memory of Python data structures
Chunking and buffering

Computer Science Topics:
Search (look-up)
Internal vs. External sorts
Multi-column sorting
Merge Sort
