In my state (Vermont), the Secretary of State has an rss feed that basically presents the results as an xml file. I’m using that to make some local results spreadsheets. Could be other states have similar things.

I’m not familiar with the Ben Eater series, but there are certainly a couple options to check out.

Mark Ferneaux did a fantastic series on the workings of pfSense. It’s a little dated, but the core concepts are still sound and apply to networking generally.

There are also several sites that do in-depth networking topics with a focus on certifications. My favorite of the bunch is Viatto.

I also quite like The Network Berg, though his videos are specifically focused on Mikrotik.

The thing that immediately came to mind was mailpiler.org. It’s been on my list to stand up for a while, but I’ve never got around to it.
