Cli

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.

Hardening a Docker image means cutting the attack surface at every layer. Start from a minimal base like distroless or Alpine. Run as a non-root user. Set the filesystem read-only. Drop all Linux capabilities and add back only what the app needs. Pin dependency versions with checksums. Scan images with Trivy or Grype before you push. Each layer of this checklist stands on its own, so you can adopt them one at a time.

Tmux handles pane splitting and window management well out of the box, but most people stop there. The real gains come from treating tmux as infrastructure. You script your session layouts so one command rebuilds your whole dev environment. You keep sessions alive across reboots so you never lose context. You add plugins for clipboard sync, fuzzy finding, and pattern matching. With tmux 3.6a and a few good plugins, your terminal becomes a persistent, scriptable IDE rather than a simple multiplexer.

Aider is the open-source AI pair programming tool that shipped before Claude Code , Codex CLI , and Gemini CLI . It is still the only major AI coding assistant that lets you pick whichever language model you want. Claude, GPT-5, Gemini, DeepSeek, Grok, a local model through Ollama : Aider connects to all of them. The project sits at 42K GitHub stars, 5.7 million pip installs, and 15 billion tokens per week. It ships under Apache 2.0, so the tool itself costs nothing. You only pay for API tokens at provider rates, which runs $30 to $60 per month for most developers.

ZFS gives you stronger data integrity. Its RAIDZ layouts are battle-tested, it checksums data end to end, and it has a proven record on NAS systems. Btrfs is the better pick for single-disk desktops and laptops. It ties tightly into the Linux kernel, compresses data on the fly, and rolls back from snapshots. You get that protection without the RAM cost ZFS demands. The right answer depends on your hardware, your workload, and how many disks you have.

For self-hosting on Linux in 2026, Podman is the better default. It has no daemon, runs rootless out of the box, and its Quadlet unit files make containers behave like any other systemd service on your box. I say that as someone whose own stack still runs on Docker . After years of reading that Podman is lighter, faster, and safer, I installed it next to Docker and measured the difference on my own hardware. Some claims held up: rootless Podman with pasta networking (Podman’s user-mode network layer) beat rootful Docker’s bridge on download throughput in every run. There is also no daemon holding memory between deployments. One claim did not survive: the often-repeated “Podman starts containers about 50 ms faster” was a statistical tie on my machine.
