**NEBUVERSE – Mein eigenes Stück Fediverse**

Darin geht’s um meine eigene kleine GoToSocial-Instanz auf Worldnode:

Warum ich sie gebaut habe, wie ich GoToSocial ohne Docker auf Debian 13 eingerichtet habe, wie WebFinger, Relays und nginx zusammenspielen – und wie ich Speicherverbrauch, Backups und Restore-Tests gelöst habe.

Kein „Selfhosting ist Magie“-Gelaber, sondern mein echter Aufbau mit echten Messwerten und den Dingen, über die man beim Basteln wirklich stolpert.

Collage-Grafik zum Blogartikel über NEBUVERSE. Groß im Bild steht „NEBUVERSE – Mein eigenes Stück Fediverse“. Daneben sind mehrere echte Screenshots der selbst gehosteten GoToSocial-Instanz zu sehen: das öffentliche Profil, die Einstellungen, die Speicher-Telemetrie und die Instanz-Startseite. Unten stehen die Hinweise „realer Aufbau“, „getestete Backups“ und „echte Metriken“. Das Design ist dunkelblau mit technischen UI-Elementen.

If #bigtech is permitted to self regulate #AI it will become a #surveillance tool for the govt.

It will be everywhere, whether you see it or not.

The next step will be controlling who can run AI, they want THEIR AI in every device. That will mean no #selfhosting or private AI.

Medical scanners, vehicles, traffic lights, vending machines, anything that processes data will have their eyes in it.

This is why they want you to hate it. Would they give you the venom to spit otherwise? Rogue AI? BS

Ich betreibe RollenspielMonster neben Job und Alltag. Ich speichere nur das Nötigste: Nutzername und E-Mail-Adresse. Mehr nicht.

Heute kam ein Löschantrag. Er war ein vorformulierter Paragrafen-Marathon mit Art. 17, Art. 12, Art. 19, Fristsetzung und der Androhung von Beschwerde und „rechtlichen Schritten“. Ohne Nutzernamen und ohne Namen, nur mit einer Alias-Adresse.

Eine kurze Nachricht wie „Hey, bitte lösch mein Konto“ hätte gereicht. Das hätte ich in zwei Minuten und mit einem Lächeln erledigt.

Verstehen mich nicht falsch: Das Recht auf Löschung ist wichtig und gut so. Aber nicht jede Anfrage muss wie ein Rechtsstreit klingen. Vor allem nicht bei ehrenamtlichen Projekten, die ohnehin das Beste aus ihren Möglichkeiten machen.

Mein Appell: Fragt erst freundlich. Wenn das nicht klappt, ist die DSGVO immer noch da.

New open-source tool: DnsAutoSwitch, a Windows service in F# (.NET 10) for AdGuard Home / Pi-hole users whose DNS box isn't always on.

Windows doesn't fail over between DNS servers deterministically, so a secondary DNS bypasses your filter. DnsAutoSwitch keeps one DNS server and switches it: primary while it answers, router when it doesn't. Hold/pause files, logs. MIT, release zip, no runtime needed.

Officially kicked off my annual self-host user survey this morning, which consists of 45 questions across several topics (including a new section on AI!).

Last year's survey received over 4,000 responses - the goal is to hit 5k this year!

Rephrasing an old joke about count of matches in the box: Dear PES, I'm watching the voltage in your power grid every 5 minutes. It always differs: 224.4V, 228.8V, 226V, etc. Are you crazy there?!

P.S. Original joke: Dear Cherepovezky matchbox factory, I count matches in your boxes every time and every time it differs — sometime there are 330 matches in the box, sometime there are 328 matches, and sometime there are 333 matches. Are you crazy?

Wer von euch hat Erfahrung mit Migration aus #Confluence zu einer self-hosted #OSS Alternative (z.B. XWiki oder La Suite Docs)?

Mich interessiert:
- Zu welchem Tool habt ihr migriert?
- Welche Herausforderungen gab es? (Datenverlust, Ausfallzeiten, Kompatibilitätsprobleme, andere)
- Welchen Tipp würdet ihr anderen geben?

Falls ihr ein passendes Forum o.ä. für diese Fragen kennt, auch gerne verlinken.

These daily backups from Proxmox's backup server may have saved my data.

When the mysql container is running, data is written to the filesystem. If I set this up properly, this would be on a persistent volume, so that it persists across restarts/shutdowns/etc.

In my case, because computers will do what you tell them to, the mysql data ends up being written locally to the k8s worker node. This lives in the dir /var/lib/containerd/io.containerd.grpc.v1.cri/containers/<random-id>/volumes/<lvm-label>/var/lib/mysql/.

Before I found that path, I figured the data had to live somewhere, and Linux can get pretty creative with mount paths, so I went looking. Based on binary text searches with xxd, and finding references to lomo soltado, I've found it. Other recipes also seem to be in there that I know I had stored.

Recovering the data from the files will be an exercise for tomorrow. But I feel a lot better about it now.

Does anyone have a #web browser bookmarking system they swear by? I research and read a lot for work and my own interests and I am both a tab and bookmark hoarder and it is a Problem. My saved links span sites, articles, images, videos, technical documentation.... you name it.

Preferably something I could #selfhost but open to considering paid services if they fit my criteria well enough.

I cannot dedicate time to sorting, tagging, or otherwise organizing links - I have tried it before and always commit to it for a day and then get overwhelmed by the sheer quantity. Or I get stuck in a cycle of constantly optimizing my tagging/folder system. There is no in-between.

Has to be low-friction to save a bookmark but I also need some search functionality for sifting through links to find what I need.

Ideally I could see what links I use frequently vs less frequently for occasional pruning.

I've considered building my own app for this and have various prototypes in different stages of disarray. Just wondering if there's anything out there I should give a try before possibly re-inventing another wheel specifically shaped for my brain.

Things I have tried:
- Raindrop
- An Org file
- Built-in browser bookmarking tools
- Texting myself links

Ping...

Is this thing working?

I moved the #Mastodon reverse proxy from #Nginx to #Caddy. I took this gist as a base: https://gist.github.com/yukimochi/bb7c90cbe628f216f821e835df1aeac1, added some from @neatnik's answer to my previous post, and followed the Nginx config, because the paths in the gist were outdated. Now I don't need a separate IP for Mastodon and have my two most important services on a single host. Oh, and I can remove certbot from the Mastodon host! Nice =)

The early stages of SolarAI-V2 local LLM server in assembly.

The 4x TESLA P100 GPUs arrive tomorrow, along with a mining rack and other stuff. This is what the hardware stack is looking like so far:

-Asus Z9PE-D16 motherboard
-CPU: 2x Intel Xeon E5-2620 V2 Processor
-GPU: FOUR NVIDIA Tesla P100 16GB PCIe (64GB VRAM)
-RAM: 128GB DDR3
-Storage: 64GB SSD for OS
-Storage: FOUR 500GB WD Velociraptor HDDs for models
-OS: ubuntu 26.04 server amd64

It will run my Hermes/Home Assistant, and is not used to generate slop.

A dual-socket computer motherboard is laid out on a dark anti-static workbench mat as an open-bench test system, surrounded by power cabling, cooling components, and connected peripherals. The main board features two CPU sockets fitted with aluminum heatsinks topped with small cooling fans, bearing an Intel logo. Multiple green RAM DIMM modules are populated in the memory slots alongside the sockets. A large passive aluminum heatsink sits near the center of the board. Thick, black sleeved cables and multi-colored power supply wires route across the bench, connecting to a black power supply unit placed to the right. Additional cabling arches over the board to power peripheral boards and cooling fans. To the left, a detached, large black cooling fan rests atop a white product box full of hard drives. In the background, an off-white vintage CRT computer monitor displays white monospaced system startup and configuration text over a dark background terminal screen, showing lines related to mounting, partition extraction, and system boot procedures. Bright blue and yellow data cables run across the light wooden desk surface around the hardware setup.

Question for those of you that use ansible for deploying/maintaining infrastructure in your labs/prods:

How did you take a manually-configured environment and migrate to ansible?
Did you reversed engineer your existing stack, or build out new using your own generated code (or other people's) and just migrate data?

#ansible #selfhosting #sysadmin #homelab

Mein Self-Hosting-Setup ist wieder gewachsen: Postiz, Open Archiver sowie Stalwart/Bulwark.

Besonders spannend finde ich das Zusammenspiel der Dienste – z. B. meine kleine Bridge von Postiz zu Bulwark: geplante Posts werden per API abgeholt, als
iCalendar-Feed bereitgestellt und direkt im Kalender angezeigt.

Auch LinkedIn läuft jetzt sauber über einen OAuth‑Workaround. Genau solche Verknüpfungen machen Self-Hosting für mich spannend. 🙂

Tips for hosting email in docker/on kubernetes?

Any helm charts you like?

Any images you like?

Any particular servers or clients you like?

Any security steps you take?

Any fancy crowdsec rules?

Firewall tips?

Please do not suggest anything LLM/AI related. I'm not interested. If I wanted that, there's an ocean of slop out there.

Update: getting great server suggestions, please keep em' coming! Also interested in TUIs, desktop apps, web mail, and android apps :)

So, based on all the replies here, on lobste.rs, and in anti-ai spaces, I've compiled an issue on my forgejo to start parsing what I want to try for myself as well as what I might offer as a service down the line. It mostly just categorizes links to all the things and adds super brief comments selected from here and lobste.rs so I can take everything into consideration on various categories of things to offer, in addition to just fun treats to try myself (like CLI/TUIs).

I'm seriously considering moving off GoToSocial to a regular Mastodon instance.

I've self-hosted for a while now, and it's generally good.

But there's a few things I miss.

The first is being able to search widely for posts on a particular topic.

Yes, relays help, but there's a big tradeoff: The more relays you have, the more storage you need.

I miss seeing posts from Lemmy and some other Fediverse apps that don't quite work with GtS.

And then storage becomes a bigger factor over time too.

#Selfhost #Selfhosted #selfhosting #GoToSocial #Mastodon

So now I need to move my #homelab. And I have two options:

1. Migrate #Mastodon reverse proxy from #nginx to #caddy (no documentation on this around the internet except uncertain assumptions).
2. Pay x4 for the internet for a business plan, where I’ll be able to rent more than one static IP.

So the question is do you, dear #mastoadmin, have a working example of Caddy config for Mastodon?

#SelfHosted #selfhost #selfhosting #AskFedi #homeserver

One day I wondered about problems between my #Matrix server and #Element desktop client. It turned out Synapse was terminated by OOM killer... and it wasn't last time that happened. Now I just started service again, without big hope it would be running long. I feel after enabling federation I finally reach that wall where lowest tier VPS just cannot bear all my services running there on minimal resources - which worked by some supernatural miracle for 7 years.

I started thinking about migrating anyway because of other reasons, but now I have more dilemma. If I have to move everything and start from scratch, it maybe could be better to use physical machine (even if not big, heavy, energy-hungry industrial server) and buy local Hackerspace network and server room storage. But now prices of any hardware are insane because of this slop hype...

I don't know what to do and I don't like it.

It's cheaper and easier than you think to create your own @peertube server 🙂

🌱 If you're non-techy you can use managed hosting through https://fedihost.co or https://cloud68.co

🪴 If you're slightly techy you can install PeerTube through @yunohost at https://apps.yunohost.org/app/peertube

🌳 If you're very techy you can use the manual installation instructions at https://docs.joinpeertube.org

GMail ist ja echt ein bescheidener Service. Die Eltern können sich aussuchen ob Sie mich bzgl. der Klassenpflegschaft über die Signal Gruppe kontaktieren oder ob Sie mir E-Mails schicken.
Jetzt habe ich gemerkt das meine Antwortmails bei GMail natürlich im Spam Ordner landen, obwohl es Antworten auf Mails sind die ich geschickt bekommen habe.
Mal wieder so eine Dreckstaktik weil solche Services einfach zu groß geworden sind. Habe da natürlich jetzt was an den Support geschrieben, aber habe da wenig Hoffnung das sich da was tut.

Falls ihr ein ähnliches Setup für Klassenpflegschaft und Co habt dann denkt mal daran. Denn das ist ja absolut perfide. Wenn deine Mails im Spam landen kriegst du dafür ja keine Rückmeldung wie du Sie kriegen würdest wenn die Mail ganz stumpf vom Mailserver abgelehnt würde.
