This document is a sequence of self-contained prompts that you can feed, one at a time, to an AI coding agent (Claude Code, Cursor, etc.) to build a PR risk classification system from scratch in your own Rails repository.
The system being built is a 3-step pipeline that classifies open pull requests as LOW_RISK or HIGH_RISK:
Static Analysis (deterministic) → Semantic Analysis (LLM) → Agentic Analysis (Claude Code CLI)
Pi-Hole's primary function is to be a DNS server with the ability to block domains, usually used for advertising, tracking or other unwanted sites. It also features a built-in DHCP Server.
Usually, your router will also have a built-in DHCP server, pre-configured from factory, and for most users this is perfectly fine. But in some cases you may want to run another DHCP server instead of relying on your router's one. This guide will help you understand how a DHCP server works and how to configure it without disturbing your network.
If you already know the networking basics, you can cut to the chase and read just the configuration part

If you encounter a problem where you cannot commit changes in Git – neither through the terminal nor via the GitHub Desktop application – the issue might be a freeze during the Git commit process. This is often caused by GPG lock issues. Below is a concise and step-by-step guide to resolve this problem.
Open your terminal and try to perform a GPG operation (like signing a test message). If you see repeated messages like gpg: waiting for lock (held by [process_id]) ..., it indicates a lock issue.
| # NOTE: When updating gems, the ENV var below will need to be _unset_, so bundler updates the correct lock file. | |
| # NOTE 2: The name 'Gemfile.dev' isn't important - it could be `dev_gems.rb` or anything else. | |
| # SETUP: | |
| # - Set the ENV var: BUNDLE_GEMFILE=Gemfile.dev in your app dir | |
| # - Add Gemfile.dev and Gemfile.dev.lock to your .gitignore (global or local) | |
| # - Copy the rest of this gist into Gemfile.dev (in your project root): | |
| # Copy real lock file to ensure it gets priority |
| # Basic key operators to query the JSON objects : | |
| # #> : Get the JSON object at that path (if you need to do something fancy) | |
| # -> : Get the JSON object at that path (if you don't) | |
| # ->> : Get the JSON object at that path as text | |
| # {obj, n} : Get the nth item in that object | |

Update 2025-07-16: Use either Revanced, NewPipe or Firefox with add-ons. Revanced is my personal pick, due to it being a mod of the official App like Vanced, but better (e.g. it has integration of Sponsor Block, Return YouTube Disklike and more).
I wouldn't recommend Kiwi Browser anymore as it has been discontinued. AFAIK it has been accuired by Microsoft and the extension support has been merged into Edge (Canary). But you'd have to use Edge. Yuck.
Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct
