DIY NAS Comparison: Raspberry Pi 5 vs. Intel N100

The Intel N100 is the superior choice for a DIY NAS in 2026 if you plan to run Plex or Jellyfin, need ZFS reliability, or want to expand beyond two drives. But the Raspberry Pi 5 remains the champion for low-power, always-on file storage where idle electricity cost is the primary concern. The right answer depends almost entirely on what you actually want the box to do.

Why Build a DIY NAS in 2026? The Case Against Synology

Synology and QNAP have spent the last few years making themselves harder to recommend. Synology introduced drive compatibility restrictions that reject non-Synology-branded drives in their newer units — drives that work identically to approved alternatives. Their DSM operating system has evolved from a convenient management layer into a proprietary platform with aggressive upselling for cloud services you didn’t ask for. A comparable Synology DS423+ costs around $500 without any drives included, while a comparable DIY N100 build with 4 SATA ports runs under $200.

Implement Dark Mode in Vanilla CSS (Zero JavaScript)

You can implement a robust dark mode using only the prefers-color-scheme media query and CSS Custom Properties (variables). This “CSS-first” approach delivers a completely flash-free experience for users while keeping your site’s codebase clean, lightweight, and JavaScript-independent.

Why Avoid JavaScript for Dark Mode

Most dark mode tutorials reach for JavaScript to toggle a class on <body>. It is the intuitive solution — add a button, read a preference from localStorage, apply a class — and it works well enough in demos. But in production, on real hardware, across real network conditions, this approach has critical failure modes that are worth understanding before you commit to it.

Self-Host Blog Comments with Remark42 (Privacy-First)

Most blogs reach for Disqus on day one because it takes about five minutes to set up. What you don’t see at sign-up is the deal you’re making: Disqus is free because it monetizes your readers. Every person who loads your comment section gets tracked, profiled, and served ads — not because they agreed to it, but because that’s the business model behind the embed script you pasted into your template.

Writing Custom Python Integrations for Home Assistant (HACS)

Creating a custom Home Assistant integration involves writing a Python wrapper for your hardware’s API and packaging it as a HACS component. This approach lets you bring unsupported or legacy devices into your smart home ecosystem with full entity control and automation support — without forking the core HA codebase or waiting for an official integration to land.

That said, custom integrations carry real maintenance overhead. Before diving into Python, it is worth checking whether a simpler path already exists.

Automate Smart Blinds and Adaptive Lighting for Better Sleep

Your home’s lighting environment is one of the most powerful levers you have for improving sleep quality — and it is almost entirely automatable. By combining motorized blinds controlled via Home Assistant solar elevation data with the Adaptive Lighting HACS integration, you can build a system that gradually shifts your home’s light temperature and blind positions throughout the day, automatically aligning your environment with your circadian rhythm. The result: a gentler morning wake-up, a more relaxing evening wind-down, and measurably better sleep.

Alacritty vs. Kitty: Best High-Performance Linux Terminal (2026)

If you want the short answer first: Alacritty is still the best pick when your top priority is raw responsiveness and minimal overhead, while Kitty is the better terminal if you want a complete terminal workspace with graphics, built-in splits, and automation hooks. In 2026, the performance gap is smaller than it used to be, so the real decision is less about “which is fastest” and more about “which workflow do you want to live in all day.”

Automating Gmail with Local AI Agents and Python

You can automate your Gmail inbox entirely on your own machine by using the Gmail API to feed messages into a private Python-based local LLM for summarization, classification, and draft reply generation. This setup delivers the kind of intelligent email management you’d expect from tools like Google’s Gemini sidebar or Microsoft Copilot for Outlook — but without ever sending a single word of your email content to an external server.

Linux Thermal Management: Fix Laptop Overheating

Laptop overheating on Linux is rarely one single bug. In practice, it is a stack problem: firmware behavior, kernel power-state policy, CPU governor choices, discrete GPU runtime power, and plain old dust in the heatsink all interact. The good news is that Linux gives you excellent visibility into every layer of that stack. If you approach thermal issues in a structured order, you can usually cut sustained temperatures by 8 to 20 C, reduce fan noise, and improve battery runtime without making your laptop feel slow.
