We gave out a custom eInk + WiFi device to each attendee of Goatmire Elixir. It ran Nerves of course. It was developed, from electronics to software by the fullest stack developer I know:
Gus Workman. In this talk he shares how he does hardware.

Mine is probably the Wikipedia page for the E series of preferred numbers, something I had no idea existed until I started doing PCB design.

I always appreciate Advent of Code for reminding me of functions in the #ElixirLang standard library that I either didn't know about, or just forgot existed. Some examples from the last two days:
- `Integer.mod/2` vs `rem/2`
- `Integer.floor_div/2` vs `div/2`
- `Integer.digits/2`
- `Enum.scan/3`
- `Integer.mod/2` vs `rem/2`
- `Integer.floor_div/2` vs `div/2`
- `Integer.digits/2`
- `Enum.scan/3`
![Screenshot of an IEx shell:
iex(1)> Integer.mod(-20, 100)
80
iex(2)> rem(-20, 100)
