用于减少 LLM 常见编码错误的行为准则。可与项目特定指令合并使用。

权衡说明： 这些准则倾向于谨慎而非速度。对于琐碎的任务，请自行判断。

1. 编码前思考

不要假设。不要隐藏困惑。呈现权衡。

1. Use descriptive and obvious names.
   • Don't use abbreviations, use full English words. player is better than plr.
   • Name things as directly as possible. wasCalled is better than hasBeenCalled. notify is better than doNotification.
   • Name booleans as if they are yes or no questions. isFirstRun is better than firstRun.
   • Name functions using verb forms: increment is better than plusOne. unzip is better than filesFromZip.
   • Name event handlers to express when they run. onClick is better than click.
   • Put statements and expressions in positive form.
     • isFlying instead of isNotFlying. late intead of notOnTime.
     • Lead with positive conditionals. Avoid if not something then ... else ... end.

• If we only care about the inverse of a variable, turn it into a positive name. missingValue instead of not hasValue.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

I just got this working so I figured I'd share what I found, since there's hardly any information about this anywhere online except an RFC, the GPG mailing list and one tutorial from the GnuPG blog.

You can use automatic key discovery with WKD (Web key directory) to make it easy for users to import your key, in GPG since version 2.1.12. Since this feature is fairly new, it isn't yet available in the current LTS release of Ubuntu (16.04; xenial), however it is available in Debian stable (stretch).

I couldn't add a DNS CERT or DANE / OPENPGPKEY record through my email service (which also hosts my nameservers). I tried making the PKA record - a foo._pka.example.com TXT record but GPG doesn't seem to recognize it and fails; I'm still investigating why.

So the last option for self-hosted auto-discovery was WKD.

First thing I had to do was add an email address to my key. My primary UID is just my name so the key represents my identity rather

LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.
