 | 
			
		||||
For the past four years, the electronics hardware shortage has been relentless. Graphics cards are no exception. In 2020, I had to wait two months to get my RTX 3080. To manage it, I joined [JV Hardware](https://discord.gg/gxffg3GA96), where a small group of geeks had set up a bot that pinged users when GPUs became available.
 | 
			
		||||
 | 
			
		||||
Four years later and with 5,000 members on the server, the RTX 5000 series is being released. Yet, no working stock bot seems to exist. Not to mention a certain “influencer” who charges users for access to a bot that doesn’t even work. He manually copies alerts from other servers like ours, which have already solved the issue.
 | 
			
		||||
 | 
			
		||||
Anyway, eager to get an RTX 5090 for my AI-dedicated machine, I decided it was time to dive into Python—with a little help from ChatGPT. Along with another member, KevOut, who helped guide me through the APIs and initial architecture, I ended up building a clean and functional bot that sends different kinds of Discord alerts—all deployable in a simple Docker container.

Six months after downloading terabytes of media, I realized that Sonarr and Radarr were copying them into my Plex library instead of creating hardlinks. This happens due to a counterintuitive mechanism: if you mount multiple folders in Sonarr/Radarr, it sees them as different filesystems and thus cannot create hardlinks. That’s why you should mount only one parent folder containing all child folders (like `downloads`, `movies`, `tvseries` inside a `media` parent folder).

- Learned never to blindly copy-paste a ChatGPT script without understanding and dry-running it

- Learned that Qwen on a RTX 5090 is more coherent than ChatGPT-4o on server farms (not even mentioning “normal” ChatGPT)

## Backup of LUKS Headers for Encrypted Disks/Volumes
 | 
			
		||||
---
 | 
			
		||||
 | 
			
		||||
I recently realized that having just the password is not enough to unlock a LUKS volume after a failure or corruption. I learned how to dump the LUKS headers from disks/volumes and to use the serial numbers along with partition names to accurately identify which header corresponds to which disk/partition (I have 10 of them!).
 | 
			
		||||
 | 
			
		||||
After struggling to do this manually, I asked Qwen3 (an LLM running on my RTX 5090) to create a script that automates the listing and identification of disks, dumps the headers, and stores them in an encrypted archive ready to be backed up on my backup server.
 | 
			
		||||
 | 
			
		||||
This script:
 | 
			
		||||
* Lists and identifies disks with their serial numbers
 | 
			
		||||
* Lists partitions
 | 
			
		||||
* Dumps headers into a secured folder under `/root`
 | 
			
		||||
* Creates a temporary archive
 | 
			
		||||
* Prompts for a password
 | 
			
		||||
* Encrypts the archive with that password
 | 
			
		||||
* Deletes the unencrypted archive
