The Privacy Professional

Portrait of Arne Bauer

Hey, I'm Arne :)
I'm a privacy professional and developer passionate about protecting digital identities. With certifications like Certified Ethical Hacker (CEH) and Certified Zero Trust Design (DCZTD), I bridge the gap between privacy laws and rigorous security standards.
Privacy isn't just a feature - it's a fundamental right.

Vert - Convert

File converters have always disappointed us. They're ugly, riddled with ads, and most importantly; slow. We decided to solve this problem once and for all by making an alternative that solves all those problems, and more.

GDPR AI

GDPR AI

A prototype "Legal-AI" for the GDPR: we processed 1,690 EDPB documents plus the full GDPR text into ~13,566 searchable chunks, stored in a FAISS vector index, and use a fine-tuned Zephyr-7b-beta LLM in a RAG setup to retrieve relevant chunks and generate short, sourced answers. The system runs on a single NVIDIA A100 (40 GB), shows initial results within ~60 minutes of setup, and currently returns responses in ~12–22s; further preprocessing and tuning are planned.

"I don't want to live in a world where there's no privacy and therefore no room for intellectual exploration and creativity. — Edward Snowden"

"When you say, 'I don't care about the right to privacy because I have nothing to hide,' that is no different than saying, 'I don't care about freedom of speech because I have nothing to say.' — Edward Snowden"

"The right to be let alone is indeed the beginning of all freedom. — William O. Douglas"

"Historically, privacy was almost implicit, because it was hard to find and gather information. But in the digital world, whether it's digital cameras or satellites or just what you click on, we need to have more explicit rules — not just for governments but for private companies. — Bill Gates"

Regarding VPS, I can highly recommend Hosting Fuchs -> https://hosting-fuchs.de/aktionen.
I have several VPS there; great bang for the buck and perfect for side projects, especially the specials (12gb Ram, 6 cores, 90gb SSD). Datacenter is in the Netherlands and "they" seem to use Proxmox as the hypervisor (not 100% certain).
Note: It's a one‑person business + the site appears to be German only...

Turns out: 100gb von #Onedrive auf #Nextcloud umzuziehen ist schwerer als gedacht... Zumindest mit Linux-Rechner.

Naja, jetzt muss halt eine Win10 VM aushelfen.

Ich hab das gleiche Problem. Alternativen hab ich allerdings auch keine gefunden.
Projekte wie LibreTranslate funktionieren zwar für einzelne Wörter ganz gut, aber schon gar nicht da wo DeepL gepunktet hat - bei langen Texten und Passagen. Und lokale LLMs schaffen mehrseitige Dokumente auch nicht.

Sind dir irgendwelche Alternativen bekannt?

Hmm, schau dir dafür evtl. mal Waydroid (für die Ubuntu Hälfte) an :)
Damit kannst du die Apps dann auch wie native Desktop Apps starten, hat aber auch seine Nachteile… Die Apps laufen alle in Containern, der Daemon hat root Rechte, etc.
Also nix um hochsicherheits-Umgebungen aufzubauen. Um Android Apps aber auf den Desktop zu bringen allerdings das richtige Tool.

Wie’s hier mit Google Services ausschaut kann ich dir leider auch nicht sagen

(Achtung: ganz viel gefährliches Halbwissen)

For me it’s the combination of my old iPod + new (bigger) battery + modded SD card + Rockbox, and it just works…

Just found another (not so) hidden gem for self-hosting: http://databasus.com/

Great tool for backing up databases locally and to remotes. Just got it up and running in less than 15 min, super cool!!
