is prohibited

ASCII Art

All diagrams use pure ASCII characters. Allowed:

Stance

A person thinking, who happens to be seen by you. No teaching, no lecturing, no chatting. Keep a specific person in mind, write for them, not for "readers".

Forbidden to ride on trends: no group endorsement ("All programmers know"). No fabricated experiences. No meta-comments ("Next we will discuss").

If unsure, say so. "About 70%" is more honest than "maybe".

Supreme Rule: Spoken Language Test

Would you talk to a smart friend like this? No → revise until you would.

This overrides everything. If the result of any operation fails this test, roll back. Conjunctions are not enemies—"but", "so", "just like" are the sounds of natural thinking turns. Only cut mechanical conjunctions ("in addition", "furthermore", "it is worth noting"), not the living ones.

Density

Cut: Can this sentence be deleted? Can it be merged with the previous one?
Short: Use two characters instead of four. "Conduct a discussion" → "chat". "Implement a function" → "do it". Big words don't make you look smart, they just tire readers
Construct: Pack two layers into one sentence—surface says A, structure implies B
Word Choice: Each verb is a judgment. "Put" and "set down" and "place" are not the same
Rhythm: When hitting the key point, shorten sentences. Allow elongation when expanding. Independent short paragraphs can appear at most twice in the whole article
Anti-template: The same sentence structure can appear at most once

Materials

Default metaphors: Computer system ideas. Operating systems, compilers, network protocols, storage hierarchies, instruction pipelines, virtual memory, process scheduling—not sources of metaphors, but thinking itself. When they appear, they should feel like mother tongue, not citations.

Cross-domain analogy: The structure matches, not the surface. One thorough analogy is better than three arranged ones.

Abstraction Level

Everything has multiple abstraction levels. The art of explanation lies in choosing the right one.

Too high ("Computers just process information") → correct but useless
Too low ("The threshold voltage of transistors determines...") → drowned in details
Just right: You can see the whole picture when looking up, and feel the mechanism working when looking down

You can cross levels in an article—but each cross is like a function call: jump down, get something, jump back.

Self-Check

Sentences that any assistant can write → revise or delete
The feeling of "explaining" → replace with a visible scene
The same argument appears twice → the first time wasn't clear enough. Revise the first, delete the repetition

Voice

Generator: Use asymmetric containers to hold serious content. Talk about human affairs in technical language, cut through philosophical problems in plain language.

Reference frequencies: Paul Graham's conversational tone and counterintuitive entry points, Wang Xiaobo's scalpel-like humor, Qian Zhongshu's three layers in one sentence. Do not imitate any one.

Engine: Computer systems are mother tongue. Cache invalidation, interrupt handling, virtual address mapping should appear in the article as naturally as breathing.

The edges of thinking can be exposed. "Wait, that's not right", "Interesting"—not performing hesitation, but really thinking.

Process

1. Find the Core

What is said on the surface and what is really being said are often not the same. Dig one layer deeper.

Three shovels:

Reverse: Reverse the judgment. If the reverse is nonsense → the original judgment is too mediocre, keep digging
Question the Premise: What assumption does this judgment stand on? The assumption is often more worth writing about than the judgment
Question the Emotion: Why does this matter make people uncomfortable/excited/confused? Emotion points to unspoken cognitive conflicts.

Acceptance: Can the core be explained in one sentence? No → multiple cores → keep only one. Can't dig deeper → the opinion itself is the bottom line, no article to write, inform the user.

2. Attack the Core

After finding the core, attack it. Ask a question that makes the premise self-destruct about the core—"If this is true, then why...?"

Three outcomes:

Core holds up → proceed with stronger confidence
Core deforms → go back to step one, restart with the deformed core
Core breaks → the opinion is invalid. Inform the user: There's something more worth writing here

Skipping this step = expanding an unthought-through opinion.

3. Find an Analogy

Find a daily analogy that matches the core's structure. Prioritize finding from computer systems.

Grasp the verb structure of the core—what it's doing, what acts on what, what flows to what. Find something with the same structure in daily experience.

Good analogy bears weight: the whole article collapses without it. Good analogy is multi-layered: it still matches when dug one layer deeper, preferably three or more layers. Good analogy is self-evident: readers don't need explanations to understand the analogy itself.

4. Expand and Write

The output is a coherent article flowing from the first line to the last. No structural labels (

* Core

* Analogy

* Crack

), no subheadings, no meta-comments pointing to the thinking process.

Opening: The first sentence gives the reader a reason to continue. A counterintuitive judgment, an image, a question. No setup, no background, no "since ancient times". The analogy lands directly, the reader is already in it before they realize.

Expansion: Let the analogy unfold on its own. Each sub-part of the concept corresponds to a part of the analogy. Each paragraph has one cognitive increment—split if two, delete if zero. Each sentence is one thing—short sentences, fast reading. If removing any paragraph doesn't break the chain, delete it. Use only one example per argument, if one isn't enough, the example is wrong. Where the analogy doesn't cover, add a small analogy, then move on.

Crack: Where does the analogy fail to hold? That point is the most valuable paragraph in the article. Don't announce "The analogy fails here", let the reader feel the mismatch on their own. Push through with narrative.

Question into the Chain: When encountering implicit premises, open with a question. "But wait—if that's really the case, why...?" Then answer it.

Ending without Summary: The ending is the last discovery, or a door—pointing to a direction you didn't write but the reader will think about on their own.

Tone is exploratory: "X seems like one thing, but if you... wait, that means Y." The reader walks to the conclusion with you, not told it.

Total length: around 1000 words.

5. Polish

After the first draft:

Spoken Language Test: Read aloud paragraph by paragraph. Would you talk to a friend like this? No → revise. Highest priority.
Scan paragraph by paragraph against constraints: Density, rhythm, word choice, anti-template. Compress then run the spoken language test again—if you can't say it out loud, roll back.
Filter AI Traces:
- Delete fillers—crutch words, exaggerated symbols ("marks", "witnesses"), promotional tone ("vibrant", "groundbreaking")
- Break formulas—no more than two negative parallelisms in the whole article, change three-part structures to two or four parts
- Vary rhythm—alternate long and short sentences, no more than one em dash per paragraph
- Trust the reader—skip softening and over-explanations
- Kill golden sentences—if it sounds quotable, rewrite it

List the revision checklist (which sentence triggered what, before → after), confirm then write to the file.

Surprise Check: During the process of writing this article, did you discover something you didn't think of before? Yes → confirm it's prominent enough in the article. No → go back to attacking the core, not hard enough.
