Obsidian PDF Export Automator
Shipped
Activity
Works great. implemented now a remote control mechanism to toggle and a prometheus data export for use in my grafana dashboards:).
Runs still strong on my proxmox install
Got student test data imported
Generataed a lot of random values with roo
At first I ran Ubuntu but GNOME was causing issues, so I switched to Xubuntu. XFCE is lighter on resources and just way simpler and more predictable in my experience.
After a lot of troubleshooting, I first tried intercepting the native file save dialog using C, but that wasn’t feasible because of sandboxing and security restrictions. I then moved to using xdotool and pyautogui. After TONS of trial and error to get the timing and window focus right, the automation finally works. It uses the Advanced URI plugin in Obsidian to open the export dialog and the save window. Then pyautogui takes over, enters the path, and saves the PDF. Xdotool had problems reliably selecting the right window.
Obsidian tries to open the PDF afterwards, in my case in Firefox, so for now I just close the tab programmatically. Still looking into disabling that directly in Obsidian.
Now I'm onto setting up change tracking and hooking everything into systemd to run it regularly.
Obsidian PDF Export Automator
I have an Obsidian vault that I wanted to automatically and reliably export as PDFs using Obsidian’s native export. Since there's no API for this, I built a Proxmox VM-based solution that watches a Git repo for changes. When updates are detected, it uses automation (via PyAutoGUI) to trigger the export, then processes the PDFs further.
Ai and randomness
A try to look at how good ai is at generating random values/words
Quantum Computing and its impact on Cryptography!
This is the source code for my research i made about quantum cryptography and the future problems with encryption. From the quantum basics to the future problems that occur when the tech gets to a certain point all of it in this 50 page pdf. Bear in mind this is my first kind of this project:)
Home Lab
Proxmox, Kubernetes & Multi-Node Cluster. This repo documents my self-hosted home lab setup using Proxmox for virtualization and Kubernetes for container orchestration across 5–6 servers (including old Macs, Dell PowerEdges, and a custom PC). Includes VM configs, k8s manifests, automation scripts, and monitoring tools. Designed for learning and experimentation.
This was widely regarded as a great move by everyone.
