Brian #1: It’s PyCon US 2023 CFP time

• Will be held in Salt Lake City, Salt Palace Convention Center
• Talks are Friday - Sunday, April 19-23
• PyCon US 2023 launch announcement
• PyCon 2023 site features images taken from past PyCon artwork
• Call for proposals open until Dec 9, but please don’t wait that long.

Michael #2: Any.io

• AnyIO is an asynchronous networking and concurrency library that works on top of either asyncio or trio. It implements trio-like structured concurrency (SC) on top of asyncio.
• Cool interpretability between native threads and asyncio
• Using subprocesses: AnyIO allows you to run arbitrary executables in subprocesses, either as a one-shot call or by opening a process handle for you that gives you more control over the subprocess.
• Async file I/O: AnyIO provides asynchronous wrappers for blocking file operations. These wrappers run blocking operations in worker threads.
• Cool synchronization primitives too.
• Catch the Talk Python episode with Alex: talkpython.fm/385

Brian #3: How to propose a winning conference talk

• Reuven Lerner
• Some nice tips and advice
• Build a list of topics
  • If you train, teach, mentor, lead, or coach already:
    • what questions to people always ask you?
    • what knowledge would help people to have?
    • where do people seem to just “not get it”?
  • If you don’t train or teach, then maybe hit up Stack Overflow…
  • From Brian: I think you can imagine yourself a year or two ago and think about stuff you know now you wish you knew then and could learn faster.
• Build an outline with times
  • This part often seems scary, but Reuven’s example is 10 bullets with (x min) notes.
• Write up a summary. One short, one longer.
  • Indicate who will benefit, what they will come out knowing, and how it will help them.
• Propose to multiple conferences. Why not?
• Practice
• (from Brian: Even if you get rejected, you’ve gained. Turn it into a youTube video or blog post or both.)

Michael #4: Sanic release adds background workers

• via Felix
• In v22.9 (go cal-ver!), the main new feature is the worker process management - the main Sanic process handles a pool of workers.
• They are normally used for handling requests but you can also use them to handle background jobs and similar things. You could probably use it for a lot of the reasons people turn to something like Celery.
• The lead developer (Adam Hopkins) has written a blog post about this feature.
• MK: Sanic has been flying a bit under my radar. Maybe time to dive into it a bit more.

Extras

Brian:

• Create Presentation from Jupyter Notebook
  • Cool walkthrough of how to use the built in slideshow features of Jupyter Notebooks.
• pytest 7.2.0 is out
  • No longer depends on the py library. So if you do, you need to add it to your dependencies.
  • nose officially deprecated, which includes setup() and teardown(). Really glad I dropped the “x unit” section on the 2nd edition of the pytest book.
  • testpaths now supports shell-style wildcards
  • Lots of other improvements. check out the change log

Michael:

• Rich on pyscript (via Matt Kramer)
• Python 3.11 in 100 seconds video from Michael
