That old Android phone in your drawer is a full sensor platform. It packs a camera, microphone, light sensor, barometer, accelerometer, proximity sensor, and a touchscreen, all on your WiFi. So don’t recycle it. You can turn it into a motion-detecting security camera, a room sensor that posts data over MQTT, or a wall-mounted Home Assistant dashboard. That dashboard rivals commercial smart displays costing $150 or more. The whole setup runs on free software, keeps your data local, and takes about an hour.

Rust error handling in 2026 rests on four patterns. You use Result<T, E> with custom enums for libraries. You reach for thiserror to derive those enums with less boilerplate. You pick anyhow to pass errors up through application code. And you add miette or color-eyre for friendly diagnostic reports. The right choice depends on whether you write a library or an application. Most real Rust projects use both: thiserror in their library crates and anyhow in their binary crates.

Yes. For many workloads, systemd-nspawn beats Docker on leanness, simplicity, and host integration. It shines on servers and homelabs where you want isolated environments without daemon overhead. You launch a container with one command, manage it with machinectl, and run it as a systemd service. All the tools already ship with every modern Linux system.

That said, Docker and nspawn solve slightly different problems. Knowing where each one wins makes the choice easy.

Bubblewrap (bwrap) is a small, unprivileged tool that sandboxes untrusted Linux apps and CLI tools with no root and no SUID binary. You build the sandbox mount by mount, so you control exactly what a program can see. It’s the same engine Flatpak runs inside. There is no daemon and no container image.

This guide is built around Bubblewrap: sandboxing desktop apps, locking down CLI tools and build scripts, network isolation, and runtime overhead. It also weighs bwrap against Firejail , the friendlier SUID-root sandbox with 1,000-plus ready-made profiles. That way you can see which one fits your threat model.

Install Windows first. Then install Linux with systemd-boot as the bootloader on a shared EFI System Partition. Add a dedicated exFAT partition for cross-OS file sharing. This setup avoids the classic problem of Windows Update wiping out GRUB , since systemd-boot entries sit next to Windows Boot Manager in the ESP without a fight. Both systems read and write exFAT out of the box, with no risk of corruption.

This guide walks through the full process. Partition strategy, install order, bootloader setup, shared storage, and what to do when Windows decides your boot order is wrong.

Caddy is the simplest reverse proxy for self-hosted services. It gets and renews TLS certificates from Let’s Encrypt with zero config. Install the static binary, write a Caddyfile with three lines per service, and Caddy handles HTTPS, HTTP/2, OCSP stapling, and renewal on its own. That replaces hundreds of lines of Nginx config and separate Certbot cron jobs.

If you run even a handful of services on a home server or VPS, a reverse proxy with proper TLS is non-negotiable. Caddy makes this painless, so there’s no excuse to skip it.
