Prompt caching lets you skip re-processing identical prefix tokens across LLM API calls, cutting costs by up to 90% and reducing latency by 50-80% on requests that share long system prompts, few-shot examples, or document context. Anthropic’s Claude offers prompt caching with explicit cache_control breakpoints, OpenAI’s GPT-4o supports automatic prefix caching, and local inference servers like vLLM and SGLang implement prefix caching natively. The rule: put your static, reusable prompt content first and the variable user query last.

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.

A wildcard SSL cert for *.example.com from Let’s Encrypt covers every one-level subdomain. You get one through the DNS-01 challenge, or, since February 2026, through the new DNS-PERSIST-01 challenge that skips per-renewal DNS edits. One wildcard cert replaces the per-service certs you’d otherwise juggle behind your reverse proxy.

Why Wildcard Certificates and When You Need Them

If you run three subdomains, single certs work fine. Each one gets its own HTTP-01 challenge, Certbot handles renewal, and life is simple. Once you pass 10 or 15 subdomains, the chore list grows. Every new service needs its own cert request, its own renewal entry, and its own way to break. A wildcard cert folds all of that into one.

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.

A fanless home server under $300 is real in 2026. Using an Intel N150 or N305 mini PC - the Beelink EQ12 Pro or GMK NucBox G3 - you get a passively cooled machine that draws 6-15W under load, makes zero noise, and handles a full stack of self-hosted services: Home Assistant, Jellyfin, Vaultwarden, Nextcloud, Immich, and a WireGuard VPN all running simultaneously without a single fan spinning.

These chips genuinely changed what passive cooling can handle at this price point.
