What were your top 3 things you learned at #39c3? Talks or otherwise.

Me:

- how meshcore routing works (and I built a MeshCore node at hardware hacking area)

- that there will be a fight against AI, “fascism,” and there will be more censorship

- a bit about how the Chinese firewall works

- I got a tropic square raspberry shield at CDC! They did a pretty cool badge with tropic square, eink, etc.

But honestly, I’m a bit disappointed that I didn’t feel any truly revolutionary idea, or something that really surprised me and enriched me. (I am not talking about meeting many amazing people, friends and new friends). So I want to fix that afterwards through crowdsourcing.

What was cool?

Let it sit and simmer for a while. An epiphany will come at the right time as you use the passively acquired knowledge to solve some old challenge in a fresh new way.

I don't touch mesh core because it's not open source. The firmware itself is open source, but the software applications used to interact with it are proprietary, and therefore that's a no-go zone for me.

There are apps that you can use to interact with it that are open source. Actually quite a few.

By your logic, you couldn't use Nostr because there exist non open source Nostr clients.

What mesh core interfaces are open source? Because the default one that everybody uses is not open source.

I know there are other programs that use it that are open source, but what interfaces are open source?
