Well, the API introduced breaking changes (streams) 2 weeks before the new edition came out. Things are settling down, but LiveView is still an v0.x product. API stability should be coming soon but its not here yet.

Learning Modbus RTU, trying to read data of my Inverter to build a real-time DIY monitoring system with Elixir.
The Inverter is a Felicity IVEM5048. The manufacturers shared a communications document, but I’ve not been able to make any headway with reading from the serial port via Modbus. any help, please

I’m currently building a tool for recording songs or audiobooks from spotify modfyp to directly sync them to a toniebox. (Don’t know if its kinda popular or even known outside of germany but it’s a childrens music box). Some automation using oban, walllaby and the spotify web sdk going on here. All nicely integrated with realtime updates utilising LiveView.
I’m probably going to open-source the code if anybody is interested (also having a hosted version of it in the next couple of days available)

As a long term object oriented programmer, i find functional programming is really amusing. so i will dweld into functional world not haskell obviously but elixir, now i’m at the course of elixir by freecodecamp it’s about recursive, and pattern mathing. i’m excited to know more. cheers.

Next: build time-series from the logs with CubDB
Then: attempt to graph Solar Production and Daily load with LiveViews

I built https://magenta-babyish-zenaida.gigalixirapp.com
As part of a job position announced at Hacker News (Who’s hiring? Thread, August 2023 Edition).
https://news.ycombinator.com/item?id=36956867 (Ctrl + F, look for ‘Hamilton’ keyword).
Relevant part:
Assignment (Waived for anyone with meaningful open-source web experience including but not limited to GSOC)
Build an authenticated website on elixir live-view (Phoenix.LiveView — Phoenix LiveView v1.2.5, tutorial https://www.youtube.com/watch?v=MZvmYaFkNJI&t=2s). After logging, the user name should be displayed on the logged-in page. There should be an icon on the password button to change the password element to text.
And it was a great opportunity for me because I finally get to take a dive in into Elixir/Phoenix that I wanted to take since 2018 IIRC. I went through several Phoenix Documentation pages because I didn’t want to just hack without appreciating the Elixir/Phoenix way of doing things.
And yet to see if I get the announced position.
