Prompt caching vs the long LLM conversation: where your input bill actually hides

I kept watching my Claude Code bill climb through long sessions, and most of it was not new work. It was the same conversation getting re-sent every turn. A multi-turn call is stateless, so your client ships the whole history each time: file reads, tool output, old diffs, all of it, and you pay input tokens on that pile again and again. So I built PromptCrunch. It is a drop-in proxy that optimizes the conversation before it reaches the model. Under the hood: it deduplicates superseded code, comp

The Ansible Playbook I Run on Every New Server

I've written before about the checklist I run through on every new server: a non-root user, key-only SSH, a default-deny firewall, Fail2ban, unattended upgrades. Doing that by hand takes under an hour and isn't hard. But "under an hour, by hand, for every server" adds up fast once you're managing more than two or three of them, and manual steps are exactly where small inconsistencies creep in, one server gets MaxAuthTries 3 and another doesn't, because whoever set it up that day was in a hurry.
