Proxmox
Install the QEMU guest agent on Ubuntu 24.04/26.04 or Debian 12/13 with one apt command, enable it in Proxmox, then power-cycle the VM. Plus why systemctl enable shows a warning, and how to fix "QEMU guest agent is not running".
Windows
Windows 11 gives the Print Screen key to Snipping Tool, so Greenshot never sees it. Turn that off in Settings or with one registry value, restart Greenshot, and PrtSc opens Greenshot again. Here's how, including on 24H2 and 25H2.
Hardware
On Gigabyte and Aorus boards, AMD virtualization is called SVM Mode and it's off by default. Here's where it lives in the BIOS on X570, B550, B650 and X870 boards, the Intel equivalent, IOMMU for passthrough, and how to check it worked.

A good 4K bitrate is 35–45 Mbps in H.264, about 20–30 Mbps in H.265 and 15–25 Mbps in AV1. Here are the tables for 1080p, 1440p and 4K, YouTube and Twitch numbers, and the CRF settings I use for archives.
Windows
The chipset decides how many SSDs, USB ports and PCIe cards your board can run, not how fast your CPU is. Here's what it does, how Intel and AMD chipsets compare in 2026, and four ways to see which one you have.

Google pulled the Picasa installer in 2016 and every "Picasa 3.9 download" today is an unofficial copy. Here is what still works, how to get your face tags out, and what I'd move to.
Self-Hosting
Changing a Proxmox host's IP takes two files and one command. Getting it wrong on a remote server means a drive to the data center. Here's the safe way for a single node and for a cluster.
Practical AI
I built an MCP server that gives Claude the whole Ghost Admin API. The first real job I gave it was an SEO audit, and it found missing meta descriptions, empty alt text and duplicate tags I'd never noticed.
macOS
Activity Monitor won't show it and the old powermetrics trick is dead on M-series chips. Here's what actually reads CPU temperature and fan RPM on an Apple Silicon Mac, and how to find what's heating it up.
Practical guides for builders: AI, Linux & self-hosting
I tried a pile of local models on my MacBook Pro M5 and kept two: Flint for fast fixes at 110 tokens/s, Qwen 3.8 27B for the harder work at 26. Here is the setup, the numbers, and how I split the work between them.
two critical bugs landed on 21 October 2026: php2shell in PHP and a Brotli RCE in Node.js. Here's how to find every affected server and container, patch it, and check whether anyone got in first.
A local AI model can handle more real work than most people expect. The problem is knowing which 80% is safe to keep local — and which 20% still needs a stronger model.
Supabase makes it easy to build fast, but a public anon key with weak RLS can expose real user data. Use this checklist before launching an AI-built app.
Stripe Checkout can be added quickly to an AI-built app, but a weak webhook can mark users as paid without a real payment. Check these webhook security basics before launch.
AI-built apps can look finished while they are still leaking keys, exposing database rows, or trusting unsafe webhooks. Use this checklist before you put real users, client data, or payments into production.
A complete Fujifilm presets cheat list covering Provia, Velvia, Astia, Classic Chrome, Eterna, Acros and more. Learn when to use each film simulation, how they affect RAW and JPEG files, and which preset works best for portraits, landscapes, street photography, and video.
Windows 11 aggressively forces Microsoft account sign-in during setup. This guide shows how to install and use Windows 11 with a local account only, using reliable command-line methods that work on Home and Pro editions.
Raspberry Pi projects often start with good intentions and end half-finished on a shelf. Not because they’re too hard — but because many tutorials quietly assume unlimited time, perfect hardware, and zero interruptions. This list is different. Below are five Raspberry Pi projects you can realistically build over a
Caddy is a modern web server that is often used as a reverse proxy in Docker environments. It is lightweight, fast, and supports automatic HTTPS out of the box. When combined with Docker and Portainer, Caddy can be a clean alternative to Nginx or Nginx Proxy Manager — but only if
Most network monitoring mistakes aren't about the tool. You're looking at the wrong interface or the wrong namespace. Here's how to find the right one, then see exactly who is using it.
If you already have a local project with real code and need to push it to GitLab—but no repository exists yet—this guide walks you through the correct, clean, and production-safe workflow. This article is written for developers, DevOps engineers, and homelab users who want a reliable Git
