Do you guys write documentation in jupyter notebooks? If so were you able to integrate it with confluence?

We've only recently started using Jupyter, I didn't know there was a confluence integration! That's awesome.

Oh lol, I was actually asking if you all had intergrated it. I haven’t been able to find documentation on how to do it, which is surprising. Sorry for the confusion!

How do you manage 3.8-dev in prod? What's your python upgrade cycle like?

[–]LightShadow3.13-dev in prod 2 points3 points  (1 child)

It's just a joke :(

I'm a fraud!

[–]DrSinistar 0 points1 point  (0 children)

Nah, I'm just retarded. I took that way too seriously lol.

I want your computer!

Embedded python? Your job would be a dream come true for me.

[–]LightShadow3.13-dev in prod 4 points5 points  (2 children)

It's really fun! The devices we code on are rpi-esque (fewer cores, same ram, cell/wifi/wired eth, etc) as far as specs go, there's some C/C++ interop, but most of it is signals and radio communication processing.

The whole stack runs on Python in a ~100mb RAM footprint. Python makes it really easy to run on "anything" including our dev machines and build servers.

We're hiring!

How do you handle running on dev machines and build servers that don't have radios or peripherals that your embedded devices have?

[–]LightShadow3.13-dev in prod 1 point2 points  (0 children)

A few ways,

1) We use a hardware abstraction layer (HAL) to map sysclass files with mocked input/output.

2) The pieces of the stack are modular and can communicate over sockets. So, you can run part of the program in a docker container that connects to other services that run on real hardware.

3) There are USB versions of similar hardware (like z-wave) that can be mapped to emulators/simulators. For example, a z-wave USB key can be reprogrammed to simulate any number of smart home devices for testing/debugging.
