Linux

A few weeks ago I shelved my “homemade Bitwarden” and moved to 1Password on the family plan. Yes, you have to pay, but sharing with the family and the ease of use make up for it. Shortly after migrating the passwords I ran into the Developer tab and its SSH agent: private keys live in the vault, they sync themselves across my machines, and every use is authorized with a fingerprint or with Windows Hello. By the way, I later found out that Bitwarden has had an SSH agent too since early 2025. You learn something new every day. It sounded too good to be true, so I set out to check whether it fit my case: several workstations (macOS, Windows, Linux), lots of servers, network gear with SSH from another era, and more and more scripts and AI agents running ssh without me being at the keyboard. In this post I go through what I learned, how I set it up, and where I do NOT use it. …

Downloading LLM models locally is something you do occasionally, but when you pull a massive 122B parameter model like Sehyo/Qwen3.5-122B-A10B-NVFP4, the download hogs the entire connection and leaves the rest of the household without internet. The Hugging Face CLI (huggingface-cli or hf) doesn’t have a --limit-rate flag, so you need to find alternatives. In this post I explain two ways to limit bandwidth on Linux using Docker (my preferred method) or Wondershaper at the host level. …

Kubernetes (K8s) is an open-source platform for automating the deployment, scaling, and management of containerized applications. It was built to work with Docker and depending on who you talk to, they’ll either say it’s hell or a piece of cake. The truth? If you’ve struggled with infrastructure (servers, networks), logged many hours with Linux, Docker and containers, it might not be that hellish and it’ll depend on how many hours you put in. Like most of my posts, this is based on documenting my Home Lab, with hours of testing, things that stop working when you least expect it. But the good thing is you learn a ton and, if you’re a bit of a geek, you even have fun. Here’s my experience, with tricks, mistakes and everything I wish I’d known before starting. …

Proxmox VE is a powerful and easy-to-use open-source virtualization platform that enables the deployment and management of virtual machines (VMs with KVM/QEMU) and containers (CTs based on LXC). If you have little experience it might be a bit daunting, which is why I recommend this wonderful project: Proxmox VE Helper-Scripts, where you’ll find hundreds of scripts to make your life easier installing CTs or VMs on top of your Proxmox. …

According to the Spanish RAE dictionary, Deshinchar: v. To deflate or reduce something swollen. That’s what this post is about: stripping Windows 11 of the apps, services, and options that simply get in the way — bloatware — that eat resources and clutter the experience. Works on a fresh Windows install as well as on one already in use. …

Having a battery backup system (UPS) is essential for home servers hosting multiple services. But it’s not enough for the UPS to supply power for a few minutes: the critical part is that, in case of a prolonged outage, the entire system shuts down in a controlled and orderly manner. In this article I document how I deployed a solution based on NUT on Proxmox to achieve this. …
