Hi, I’m Jason Scheirer. I’m a professional programmer and in my free time I’m a hobbyist programmer. I write games, I make little web toys, I talk about the passage of time. If you’re quiet on a summer’s day you can hear me whispering about JavaScript on the cool breeze.

One thing I love about Python’s practical approach to type annotations and enforcement is that it’s gradual: you can rapidly code a large ball of mud and get it working, then refine it to make it safer with typing later on. Chalk this up...
I wrote a blog post that is now on my employer’s engineering blog. I used my normal Markdown/Hugo/Github flow to author and edit it, so if you want to see the revision history it’s right here.

This was inspired by a short chat I had with a coworker, trying to give a simple, 15 minute explanation of something that took me a decade to wrap my head around due to poor teaching resources online. Async programming in modern...
Python has continued to progress and introduce new features and modules. In this post I’ll cover features I haven’t used much (or at all) and how I plan on using or not using them. Walrus Operator I’ve been aware of this for a few years....
I can’t understate the importance of how much the following have changed and improved the way I write Python and have confidence in its correctness: Continuous Integration Black Dataclasses Mypy Type Hints Continuous Integration This...
There is a convenient but untrue fiction about Python that the language specification is somehow cleanroom and CPython is actually “just an implementation.” This has always been false, and harmful at best. Look at __dict__. Near every...
Let me spell something out for you trickster-meanies: # HELLO I AM thingy.py __all__ = [X, Y, Z] X = True Y = True Z = True Reasonable, right? >>> from thingy import * Traceback (most recent call last): File "<stdin>", line 1, in...
End product Please disregard the poor camera placement or the labels, it has since been fixed. Thinking Back, It Was All So Simple Now we have the system up and running, let’s talk random obstacles and next steps. This is something of an...
Hardware The RPi The Raspberry Pi is a (I think) Pi 3 with Wifi I found in the garage with a cheap clear acrylic case. It might have been a RetroPie rig in a prior life? Or one I was “gonna get around to” doing something with and finally...
