I collected some bullet points over the last weeks:

btc pay server POS (alternatives to WoS)

install/experience foss OS (Graphene) on mobile

how does Alby works (Alby Hub)

Saver Messaging Apps (set up a matrix group chat)

ecash explanation

structurual differences between lightning wallets (self custody - LSP - ... - WoS)

It doesn't mean that I can tell much about it, but I would like to know more about it.
