Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

The latest thing I've cobbled together with n8n is a routine that goes out to https://sol24.net/ and pulls in the current Aurora forecast and the current 7 day video of solar flares into my dashboard. I've always had a fascination with how the sun affects the earth and the protective layers of our atmosphere, since I was a child. I built my own 5 watt, code only, transmitter and receiver and would set in my room late nights collecting QSL cards and talking to people from all over the world . I quickly learned that the ionosphere and other protective layers affected how far my little 5 watt signal would bounce. Solar flares burn holes in the ionosphere and prevent a good bounce halfway around the world. So the challenge was to pick days where there was good ionosphere coverage, and minimal solar flares in conjunction with antenna positioning.
This is the current video which takes you from 11/29 to 12/5. It's mind boggling to me the absolute power and energy represented: https://sol24.net/data/stereo_7day_euvi304.mp4
You could probably conjure up something in bash to do this, but I really like working in n8n.
