Why does an idle NVIDIA RTX 4090 draw ~30W on Linux but only ~10W on Windows?

I spent a day digging into NVIDIA kernel parameters to bridge this gap in my Kubernetes-based homelab.

The Result: A 60% reduction in idle power waste with just 3 parameters.

Here’s the breakdown:👇🔗

A curated list of #git pre-commit hooks for secret detection, linting, and conventional commits.

This is a living document I'll be expanding as I find new ways to automate codebase quality. Feel free to bookmark it if you find these tools useful.

Following up on my #Proxmox + #Terraform auth setup.

I've documented how I quickly provision Ubuntu VMs on Proxmox using Terraform and Cloud-Init.

Covers cloning from templates and injecting network/SSH configs automatically. 🔗 ⬇️

I just documented a quick reference for connecting #Terraform to #Proxmox. Secure, minimal setup, ready for quickly provisioning VMs:

1. Create a scoped role
2. Generate a non-privileged API token
3. Export secrets

🔗 ⬇️

If you work with Proxmox, Cloud-Init images are a huge time-saver.

I wrote a short guide on creating a reusable Ubuntu 24.04 VM template: (1/3) ⬇️ 🔗

Why? Because in Dockerfiles:
- `ARG` before `FROM` → only available to `FROM`
- If you want to use that same `ARG` later, you must re-declare it after `FROM`
✅ Correct:

I had something like this.
But the condition was never true — even with:
`--build-arg TARGET_ENV=production`.

Debugged a Dockerfile issue for way too long: a RUN condition that should have matched — but never did.
Subtle mistake. Here’s what happened ❌👇
