Guides

A beginner's guide to CPU selection: cores, clock speed, TDP, and how to pick between Intel and AMD for gaming, content creation, or a homelab.

How air coolers, all-in-one liquid coolers, custom loops, and passive cooling actually compare, and how to pick the right one for a build.

How Proxmox VE, TrueNAS SCALE, Kubernetes (k3s), and bare Docker actually compare for a homelab, and how to pick between them.

How to size a PSU for a gaming or workstation build: the sizing formula, efficiency ratings, and what actually matters versus what's marketing.

How to set up a quiet PWM fan curve for a homelab server that runs Docker or Kubernetes around the clock, without risking thermal throttling.

Why a machine for video, 3D and photo work should not contain the same parts as a gaming PC at the same price, and which components actually change how long you wait.

Most projects that adopt Kubernetes would have been fine without it. Where the threshold actually is, what Docker alone gets you, and when Podman is the better default.

A machine that runs continuously has different priorities from one you switch on to use. Idle power, noise, memory, drives and the mistakes that make a homelab annoying to live with.

NVMe or SATA, Gen4 or Gen5, how much capacity, and why the fastest drive on the shelf is rarely the one you should buy. The parts of the decision that don't expire.

Setting up a home Kubernetes cluster: what hardware actually works, why the networking is the hard part, and the honest case for using Docker Compose instead.

A repeatable way to diagnose Linux failures: define the problem precisely, read the logs, change one thing, verify. With three worked examples from boot failures to 502s.

The fastest consumer graphics card there is, and the reasons most people buying one don't need it. Power, memory, monitor requirements, and who it's genuinely for.

How to split a build budget between CPU, GPU, memory and storage: what actually changes the experience at each tier, and the parts people habitually overspend on.

CrashLoopBackOff, ImagePullBackOff, OOMKilled and the Docker build failures behind them. What each error actually means, and the order to check things in.

ModuleNotFoundError, Cannot find module, command not recognized, image not found. Four errors, one cause: the thing usually exists, and the resolver is looking somewhere else. How to find the gap instead of guessing.

Access denied in MySQL, PowerShell, Linux and Docker. The error names a permission, but the cause is normally identity or policy. How to make each system tell you who it thinks you are.

Three cheap, durable, electricity-free brewers that make completely different coffee. What each actually produces, what it demands of you, and which one belongs on your counter.

Ryzen 7 9800X3D is genuinely discounted. The RX 9070 XT is not, and is up 8 percent since August. Real prices, real dates, and the number to wait for before buying a GPU.

A processor ranking with actual PassMark CPU Mark scores and the date they were pulled, plus the reason the top of the chart is the wrong place to shop if you mainly play games.

The grinder is the piece most people upgrade last and should upgrade first. What burrs actually do that blades cannot, hand versus electric, and where the money stops making a difference.

Coffee is about 98 percent water, which makes water the ingredient nobody thinks about. Here is what minerals actually do to extraction, and the cheapest fix that works.

A graphics card ranking with actual PassMark G3D Mark scores, the date they were pulled, and a straight answer about what a single benchmark number can and cannot tell you before you spend money.

What espresso actually requires, which cheap machines can and cannot deliver it, and the uncomfortable fact about where your first budget should go.

A first-person build diary: a new Ryzen 9 9950X, a motherboard that wouldn't even POST, and the USB BIOS Flashback feature that saved the weekend.

FPS, resolution, and graphics settings explained in plain, friendly language -- with real, cited benchmark numbers from Baldur's Gate 3 and Starfield, not guesses.

A reader-pattern case study in CPU bottlenecking: why bolting a new GPU onto an aging platform sometimes buys almost nothing, and how to actually diagnose it before you spend the money.

Real coverage numbers, real prices, and the total cost including optional subscriptions: which mesh system actually fits your home and ecosystem.

The real total cost, not just the kit price: monitoring plans, add-on sensor costs, and which system fits renters vs. homeowners.

Three real drip machines across budget, mid, and splurge tiers: no pods, no proprietary cartridges, just water, a filter, and grounds.

Five gooseneck kettles across stovetop and electric, budget to splurge, and what actually changes between them.

A decision guide to real coffee gear across price tiers and rituals: deliberately no Keurig, Nespresso, or any pod-based machine.

Chemex's bonded paper filter against Bodum's reusable stainless mesh: how each changes the cup, the cleanup, and the long-term cost.

The grind size and water temperature every brew method actually needs, why they matter, and how to adjust when a cup tastes wrong.

The real variables in cold brew: grind size, ratio, steep time, and which cold brew maker fits your routine.

The actual mechanics of a good pour-over: ratio, water temperature, bloom time, and pour pattern, step by step.
