I am not an expert on security and I don’t know how to setup ddns, but I simply use Tailscale VPN to access my RPi4 homeserver running Umbrel from outside of my home, I simply installed Tailscale in my Umbrel and in my phone, and when I want to access from my phone Immich, Nextcloud or any other app running on my Umbrel. I simply enable the Tailscale VPN. Maybe it has some limitations, but is the simpler way I found, and based on what I read, it is more secure than exposing a port in the router, but not sure.

I don’t know why you say that bitcoin is mostly used to scam people and to purchase illegal goods. I agree that maybe a small fraction of people is using it as a currency. But, in my case, most of the people I know who have bitcoin, just have it as a store of value. Maybe I am lucky and know a lot of those “responsible heroin users” who understand that there will be only 21 million bitcoins, so what makes it valuable is its scarcity, and as long as central banks keep printing money out of thin air, bitcoin demand will grow, at least among those who understand it.

I don’t want to say crypto in general, but Bitcoin in particular was born after the 2008 crisis, as a decentrized form of money, meaning storing value against the inflationary fiat money that the goverments can print in a centralized manner, destroying all your savings. I think any technology that empowers decentralization is positive. Same as fediverse. And in the case of bitcoin, having a decentrized money it’s a really positive tool for freedom to avoid centralizing the power in the governments. But I am curious on knowing why you say that there is no positive uses.

Umbrel OS

I use Logseq in my PC and my phone and I unse Syncthing to sync the notes accross my devices.

The alternatives already exist and they are build on Nostr and it has different apps/clients to interact with that protocol. For example Olas is a Instagram-like and tik-tok-like app, and there are also many twitter-like or mastodon-like apps such as Amethyst or Damus

In Graphene Os site, it says it has 3 years of support left. Normally my phones don’t last that long. So it’s fine for me, but obviouly I would recommend going for a newer Pixel version if you find a good deal. Edit: typo.

If you buy them second hand they are not expensive, I bought recently a Pixel 6 in backmarket for 200€ and it works perfectly.

Does this EU’s Digital Markets Act also applies for Android and all the preinstalled apps by Google and the phone manufacturer?

I really hope so, it should be taught, because for me it was a slow learning process. First I started using Obsidian, and moving all my notes from Evernote, Notion, and others manually. After that I moved to Logseq, which is like Obsidian but open-source. And the last step was using an open-source syncing tool (Syncthing) to have my notes synced locally in all devices. And now I have been 2 years self-hosting my notes in a really easy way.
