On my trip back from china this week I watched a Chinese movie about their nuclear bomb project. Basically the equivalent of Oppenheimer. Quite interesting movie and now I am reading this
Vincent_Yan404 12/28/2025||
Yes, it's really like the small town in Oppenheimer.

Sounds interesting. What's the title?

The naming is almost too perfect. Someone in the bureaucracy looked at a classified city that couldn't appear on maps and called it "404." Either that's dark humor from an engineer who knew exactly what they were doing, or it's a coincidence that's funnier than any joke.

Also curious about the zoo. A zoo in the middle of the Gobi Desert for a city that doesn't exist. What happens to the animals when a place like that shuts down?

You are a great writer. Would love to hear what came next and eventually how you found your way to HN. :)
Vincent_Yan404 12/29/2025||
I asked AI where should I publish my article, it said Medium at first. I submitted to illustration and 10 days later, the article is still pending review right now. So I ask AI again, what should I do? It says HN is the best but also toughest, it's hard to show in the front page. After I tried, I think I kinda made it.

Thank you so much! That means a lot to me.I'll be posting Part 2 very soon on my Substack to continue the story. Hope to see you there!"

Is the “404: not found” error code actually a humorous reference to China’s secret nuclear city?

After all, HTTP was invented at CERN, a nuclear research institute. Staff there would presumably have been aware of “404” and probably made jokes about the fact that it didn’t exist…

It's a coincidence.It’s defined both a digital void and my childhood home is the kind of irony.

>> Witnessing such scorched-earth containment makes the modern definition of nuclear power as the ‘cleanest energy’ completely incomprehensible to me.

It's called bad governing. To connect nuclear "not clean" with such bad governing is bit much.

Vincent_Yan404 12/28/2025||
You make a fair point, and from a purely technical or policy perspective, I agree that bad governance shouldn't be conflated with the potential of nuclear technology itself.

However, as a writer, I’m describing the subjective reality of growing up in that environment. When you see 'scorched-earth' measures taken to manage a city, it shapes your visceral perception of that power, regardless of the science behind it. My goal isn't to debate nuclear policy, but to capture how that specific 'bad governing' colored the way we, as residents, perceived the very energy that defined our lives.

This argument that nuclear power generation is clean if you ignore the times when it isn't seems a bit no-true-Scotsman to me. It's a thing I've changed my mind about more than once in the past. What sways my thinking now is:

- most nuclear power does indeed seem to be well run with minimal pollution. - when it goes wrong, the consequences are awful and long-lived (I can, off the top of my head, name two sites that are dangerous decades after they were polluted. I suspect there are others that don't have the same cultural resonance for me. - the alternatives in terms of renewables and storage are improving seemingly from one day to the next.

The long term consequences, and human frailty in the face of a requirement for total and eternal vigilance convince me that the risk outweighs the reward. Where nuclear power once seemed [to me. I appreciated that some people have always been anti-nuke] like the least bad option compared with e.g. coal, now there are better ways to make our lives work.

If the endless 50-years-in-the-future ever actually expires and we get practical fusion power, it'll be interesting to see how this changes my thinking. Perhaps that will will have fewer toxic side effects when it goes wrong.

The same can be said about wind and solar. Nothing about producing the rare earths required is clean.

Even if we include Chernobyl, nuclear is still by far the safest source of energy when looking at deaths per TWh generated.

> I can, off the top of my head, name two sites that are dangerous decades after they were polluted

Two? I can only count one. Fukushima is almost perfectly safe today, although exclusion zones still exist.

If I set up a wind generator and then leave it with no maintenance it's a risk to an area a little bit bigger than its maximum height. If I leave a nuclear reactor unattended it's a risk to hundreds of thousands of square miles.
sgjohnson 12/29/2025||
Most likely still worth it when comparing by unit of energy produced.

I don't know about "bad governing". It sounds more like a rigorous containment policy when nuclear technology was at its infancy in China. (Regulations are written in the blood of your predecessors - https://old.reddit.com/r/LifeProTips/comments/ud3lt4/lpt_osh... ). It is also about preventing accident leakage of information and preserving secrecy. For e.g. In the 1970s, India learnt that Pakistan was working to create a nuclear weapon when Indian agents in Pakistan collected hair samples of Pakistan's nuclear scientist, from a barber shop where they got their hair cut - traces of plutonium radiation were found in the hair samples, and Pakistan's nuclear weapons program got exposed.

The LLM flipped from “scorched earth” to “ bad governing” as the sofa faded from its context window.

The metaphor says maybe “extreme cleanliness is like war”, second pass war is bad governing…

Don’t engage with it.

At this point, you’re arguing with an LLM, not a coherent storyteller. The events your question refers to have been downgraded in the context window.

It’s like the game of twenty questions where the LLM doesn’t have a persistent secret object, it’s just simulating consistency.

Thanks for the info. I wouldn't know anything about this as I just totally avoid AI tech - whether for online search or coding or some other service. It just doesn't excite me. (By the way, how do I know you are not AI too? ;)

Precisely.

Especially when comparing the number of deaths(1) from then-China's favourite energy source or simply Uranium's efficiency(2) and the fact we know now how to recycle most of the waste(3)

Sure, I prefer the solar too, but I agree the governance is the bigger problem in the example from the story.

This was a great read. Can't wait for the next installment. Where do you live now?
Vincent_Yan404 12/28/2025|
Thank you! I live in Toronto right now.

Cool post!

Always interesting to read about people's lived realities that are completely different

Vincent_Yan404 12/28/2025|
Thank you! It was indeed a unique place to grow up. I'm planning to publish the next chapter shortly, so stay tuned.

Thanks for sharing your story. I was also born in 1991, and it’s crazy how much where a person is born shapes the whole growing-up experience. Looking forward to part 2!

This is really cool, it reminds me of Novosibirsk which I learned about from reading Red Plenty, Francis Spufford's historical novel about the city.

"I ran wild, waving a red inflatable toy hammer."

I think that I see the word "Coke" in the picture of you holding the hammer.

Was this for Coca Cola?
