You can use HDMI-CEC commands through Home Assistant ’s HDMI-CEC integration - or a CEC-capable device like a Raspberry Pi running cec-client - to control TV power, input switching, and volume from automations and dashboards. Instead of juggling three or four remotes, you wire up a “Movie Mode” automation that dims the lights , powers on the TV, switches to the correct HDMI input, and sets volume to a comfortable level. One tap. Done.

Use Home Assistant ’s built-in packages system. Instead of one giant configuration.yaml that grows into a 2,000-line beast, packages let you split YAML by function: packages/lighting.yaml, packages/climate.yaml, packages/security.yaml, and so on. Each file can hold any mix of automations, sensors, scripts, input helpers, and templates. To tweak your thermostat logic, you open packages/climate.yaml. Nothing else.

As of Home Assistant 2026.4, packages support every integration domain, !secret references, Jinja2 templates, and nested subfolders. The rest of this post walks through setup, migration, design patterns, and Git workflows that make packages practical for a real smart home.

Linux 7.0 makes Rust a permanent part of the kernel development model. Kernel builds now use stable Rust releases anchored to the Debian stable toolchain. Drivers like NVIDIA’s Nova and Android’s ashmem already run on millions of devices. This policy change lets developers use a language that eliminates memory-safety bugs at compile time.

Why the Kernel Needed Rust in the First Place

Bringing Rust into the kernel wasn’t about ideology. About two-thirds of kernel security bugs come from memory issues like buffer overflows and use-after-free errors. These are the expected costs of writing software in C. Manual memory management gives control but lacks guardrails. One mistake can lead to a major exploit or a system crash.

SQLite is the right default database for most apps. With WAL mode on, it gives you unlimited concurrent readers and one writer. That writer can sustain thousands of transactions per second on modern NVMe drives. SQLite also handles files up to 281 TB and needs zero config, zero extra processes, and zero network hops. Start with SQLite. Move to PostgreSQL only when you hit a real, measured limit, not a guess.

CSS Anchor Positioning is a browser-native feature that pins any absolutely-placed element to another element in the document. No JavaScript required. With the anchor() function, position-anchor property, and @position-try rules, you can build tooltips, dropdown menus, and context menus in pure CSS and HTML. It now works in Chrome 125+, Firefox 132+, and Safari 18.2+, which covers about 91% of browser traffic. Pair it with the HTML popover attribute (Baseline 2024) and you get show/hide toggling, keyboard dismissal, and top-layer stacking for free. The JavaScript tooltip library is dead for most use cases.

You can build a fully functional feature flag system using a JSON configuration file, environment variable overrides, and a single evaluation function in roughly 100 lines of Python. This gives you gradual rollouts, kill switches, and per-environment toggles without paying for LaunchDarkly , Unleash , or any other SaaS platform. The core pattern is straightforward: define each flag with a name, a boolean or percentage-based rule, and a list of target environments, then evaluate it at runtime through a thin SDK you own and control completely.
