I chose to continue with my current setup until I get the time and motivation to upgrade.

I will build a new server from scratch. For that, I bought an used mainboard for a few bucks, which has 6 SATA slots.

I use Casa"OS". It’s fine, but nothing groundbreaking. Cockpit for example can do pretty much the same, and for Docker containers, I nowadays mostly use docker compose.

But hey, it helped me a quite a bit in the beginning, and it’s cool. Pretty basic, but enough for most people, mainly beginners.

Logseq and Obsidian are only similar on the first look, but very different usage wise. Both are very open with a plugin system, and you can modify them to turn them into one eachother.

So, if you want only FOSS, then Logseq is the only choices you have.

But Obsidian is, even though it’s proprietary, very sane. Open plug-in system, active community, great devs who don’t have much against FOSS, and more.

Obsidian

• More similar to a classic note taking app, like OneNote, but with a lot of features. Hierarchical structure, and more of an “essay” style, where you store a lot of text in one page.
• Page linking is only done when you think it makes sense
• Has been a bit longer around than Logseq, feels more polished
• Great sync and mobile app, which support plugins from what I’ve heard

Logseq

• Non-linear outliner. Every page is on the same level, but within a text passage, the indentation matters (parent-child-relationship)
• You create a LOT of more pages. Most of my pages are empty. They are mainly there for linking topics. I rarely create pages manually.
• The journal is where you write most stuff. You then link each block to a page.
• Logseq a bit “special”. May not be for everyone. I for example am a bit of a disorganised thinker, who mentally links a lot of knowledge and throws concepts around all the time. Logseq is my second nature, because it’s more flexible. My GF on the other hand is more structured, and prefers something like Apple Notes, or, if she would care about note taking, something like Obsidian.
• The mobile app isn’t great. It’s fine when I’m not at home, but the desktop version is the “proper” one, and mobile/ iPad a second class citizen.
• Sync is only experimental for now. It will soon be officially supported (hopefully) and self hostable, but it worked fine for me.

I don’t see any problems with that. Even I (and probably most others here), who are FOSS advocates, think Obsidian’s model is fine.

The devs surely get why FOSS is important, and try their best to match the pros of open source. They even stated that if the company goes bankrupt or they stop developing the app, they’ll open source it.

One major thing they do absolutely right is how the notes get stored. On other note taking apps, it’s a proprietary database, often “in the cloud”, where your notes get hold hostage. Here, they’re just Markdown files, and the whole thing is pretty open, encouraging a strong community.

It’s similar to Valve/ Steam. Proprietary, but liked by most Linux people.

Logseq! Right now, you can only self host the database and sync it with Syncthing for example, but the dedicated sync feature is currently in beta and will be self hostable afaik.
