This is the most batshit conference presentation I've ever been part of. Zach announces something for Ash, as per usual, but let's just say that's mostly the backdrop..

A letter to ourselves - Zach Daniel
Zach tends to give talks about Ash. Which makes sense. While this talk does involve Ash it hits on something deeper and more fundamental. Revolutionary technology. Heck of a way to start off day 1 of…

This was such a fun project to work on. Thanks @lawik.bsky.social for hosting such a great conf!
Stay tuned for what comes next in the world of Nerves + e-ink 😄

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)
-20
iex(3)> Integer.floor_div(-20, 100)
-1
iex(4)> div(-20, 100)
0
iex(5)> digits = Integer.digits(1234)
[1, 2, 3, 4]

Y'all, I need help testing if this implementation of Open Graph images works properly.
If everyone who reads this could send the link to 20 friends and remind them that the next Nerves meetup is on Wednesday that would be soooo helpful 🙏😜

It’s not the first time I’ve said this (and I really hope it’s not the last!). But you gotta hand it to the DigiKey logistics department.

And it was like 20 different components! With free shipping! And DDP! 👏

Oh man I got called out in this one 😂
But this is actually a perfect example. Chip designers love putting random config bits in unrelated registers. Adding additional registers requires more transistors, more processing, more verification, etc so they cram it all into as few as possible.
