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.

If you just ran rm on something important and you’re in a panic, stop touching that filesystem right now. Run mount -o remount,ro /dev/sdX to remount the partition read-only first. Every write to the disk after deletion cuts your odds of getting those files back. Here is the short answer. For ext4, try extundelete or debugfs first, then PhotoRec as a fallback. For Btrfs, roll back a snapshot if you have one, or use btrfs restore if you don’t. The right move depends on your case, so read on.

Tailscale builds a private WireGuard -based mesh VPN across all your devices with almost no setup. You install the client on each machine and sign in with your identity provider. Every device then gets a stable 100.x.y.z IP that works no matter the NAT, firewalls, or network changes. Tailscale v1.96 adds ACL tags for per-device policy, exit nodes, subnet routers, and MagicDNS for hostname lookups. For homelabbers, it is the easiest way to link a server, cloud VPS, phone, and laptop into one network.

Terminal apps used to mean raw curses calls and a lot of pain. Today, Python’s Textual and Rich libraries have flipped that. In under 50 lines of Python you get a full-screen app with styled layouts, widgets, keyboard control, and live data. No web browser. No Electron. No JavaScript. This post walks through both libraries, shows how they fit together, and builds up to a full working example you can extend right away.

Gemini CLI is Google’s open-source terminal AI agent. It offers a free tier with 1,000 requests per day and a 1M token context window. While its code quality trails Claude Code, it provides zero-cost access for developers. It’s now the most-starred AI coding CLI on GitHub. Update: Google discontinued the free, Pro, and Ultra tiers on June 18, 2026 and moved users to a closed-source successor, so read the Antigravity CLI migration guide for what changed and how to keep the old CLI running.

You can switch your Linux install from X11 to Wayland without reinstalling anything. The move comes down to picking a Wayland session at your login screen. After that, three things need follow-up: Xwayland for legacy X11 apps, input setup through libinput instead of xorg.conf, and a few environment variables. Those variables let toolkits like Qt, GTK, and Electron render through Wayland instead of falling back to X11. Most people finish in an afternoon. You can keep an X11 session as a fallback until you’re happy everything works.
