dluan··on Spinel: Ruby AOT Native Compiler
For some context, just presented by Matz at RubyKaigi 2026. It’s experimental but he built it with help from Claude in about a month. Successful live demo.

It’s named after his new cat, which is named after a cat in Card Captor Sakura, which is the partner to another character named Ruby.

dluan··on 4D Doom
Mid 30s, also have kid and sleep loss but not as bad as before.

I actually noticed serious mental decline when I was burned out in my late 20s. There were real physical symptoms like not being able to look at a text editor for more than 2 minutes. Post recovery of that, I actually feel like my brain recovered a lot once I started learning languages very seriously (mandarin and japanese), starting a few years ago. Brain feels healthy now but I'm acutely aware of where it's not as sharp as before. Playing around with this felt a little like when my brain is trying to build a new grammar dictionary.

dluan··on 4D Doom
I feel like now that I'm older, my brain just can't fully understand it say as quickly if I were younger. Makes me wonder if younger more plastic brains can adjust to having to juggle more dimensions than crochety old ones like mine with very rigid 3D grooves baked in. Or brains from other animals.

I guess taken to the logical extreme, what does the brain of someone/thing that's good at playing this (or any game of N dimensions) look like?

dluan··on How the world’s first electric grid was built
Sun Yat Sen, the father of China, was educated in Hawaii when it was still a kingdom (at Obamas alma mater Punahou), and famously said it was during that time that he learned what civilized governance looked like. Back then, Hawaii was seen as something akin to how we looked at Japan in the 2000s or China today. A futuristic, socialist (free education, free healthcare) constitutional monarchy that blended elements of Europe, America, and Asia into its governance structures.

Hawaii was so flush with productive sugar cane and so technologically advanced, that it was seen as a target by the American cartel there that it had to be violently toppled.

There's great movie footage of the first Waikiki electric street car heading up towards Diamond Head, taken by Thomas Edison when he visited Oahu. I get sad every time I'm on Kalakaua Avenue knowing that we could've had real public transit in Honolulu if it weren't for America.

dluan··on Online astroturfing: A problem beyond disinformation (2022)
We have a massive poisoning of the commons catastrophe coming, driven by further authoritarian government overreach and control. I've seen no one working on this, and in fact most people on HN seem to be working on ways to further exacerbate this problem. I don't just mean half solutions like tor or social protocols that let you in and out of walled gardens.

There's still a tiny window of opportunity for engineers to come up with or design technical safeguards, but eventually this problem will move past the realm of what's easily solvable and out of our hands, and into policy makers hands. A big part of me feels like that window is already slammed shut.

dluan··on I am directing the Department of War to designate Anthropic a supply-chain risk
it's so funny to me that anthropic was created specifically using the virtue signaling line of defensive safety against bad actors (ie the woo woo bad guy of chinese dictatorship), yet the real danger was always coming from inside the house - your own government being an absolute evil clusterfuck.
dluan··on I am directing the Department of War to designate Anthropic a supply-chain risk
this is inacccurate, tesla was the first mover in china's EV market and held by far the largest market share for over a decade. obviously that was in large part to elon hiring chinese systems engineers to build out the first super factories and using chinese robotics tech. but ever since losing those key early leaders, tesla has completely fallen behind.

so EOL announcement without saying when it will be, but eventually.

dluan··on Jack Kerouac's 37 metre-long, first draft scroll of On the Road to be auctioned
A lot of people will say to start with the most well known stuff - Naked Lunch, On the Road. I never liked Naked Lunch much, but On the Road is still probably the best gestalt depiction of the post-war America that was smack in the middle of transitioning from post-depression NYC jazz to California hippie. Once you have a feel for what that time and context was, then the poetry makes more sense.

It's been a while, but I remember enjoying a lot the very early writings that were collected posthumously in Atop an Underwood, very easy to pick up arbitrarily. Other good ones - Desolation Angels, Dharma Bums, The Town and the City, Subterraneans, Satori in Paris. Those are all formative. There was another posthumous release And the Hippos Were Boiled in Their Tanks which was just a funny and ridiculous retelling of a murder of a friend.

Of course, lots of fun stuff from Bukowski, Gregory Corso, Gary Snyder, Phil Lamantia, John Clellon Holmes, Richard Brautigan, short stories and poems. Neal Cassady Collected Letters, 1944-1967 was probably my single favorite book back then. I'm sure I'm forgetting lots of stuff.

dluan··on Jack Kerouac's 37 metre-long, first draft scroll of On the Road to be auctioned
I used to be a hardcore beatnik collector in my college days, basically gobbling up any of books, pamphlets, first editions from everyone on the bus or even mildly associated. But as I got older, I realized how much of it was really just reactionary circle jerking without much meaningful substance, save for Ferlinghetti and Ginsberg at times. The rest of it, especially Kerouac, was basically just documenting a special time and place in niche west coast history, and the real heroes I've come to recognize were the characters like Neal Cassady who's writings I also had. But it's like people today who had parasocial relationships with pre-Covid Dimes Square. Pretty weird to make Cumtown your entire personality, but those people exist. Probably some dork with 2010s hair like Mark Pincus or Dennis Crowley will buy this.

dluan··on You’re not burnt out, you’re existentially starving
"lying flat" and unemployment are a thing, but nowhere near as bad as media makes it out to be. My experience is mainly in Shanghai and Hangzhou.
dluan··on You’re not burnt out, you’re existentially starving
I think it's simpler to just appeal to every entrepreneur's spider sense - go where the great people are. It really does feel a bit like how Silicon Valley and San Francisco felt in 2000s-2010s. Caveat of course, which is even before 2008, aware insiders of SV were trying to warn that the Goodness of the internet was being squeezed too hard, that VC was turning to rent seeking too soon, the cart is way too far ahead of the basic research pipeline, etc. And of course, there's corruptible people, terrible overwork, insane competition, bad stuff etc in China too.

But there's a determined, undeniable sense of "we're going to make the world a better place", and you can physically see and touch it in China. Once you take a big inhale of that air, you realize just how much you missed it and needed it.

dluan··on You’re not burnt out, you’re existentially starving
This is absolutely going to fall on deaf ears here, but I moved with my wife and 1 year old to China for 4 months and became the most productive in more than a decade.

Safety, convenience, infrastructure, everything around you isn't solely designed to price gouge you and exploit you, and all of that was just a minor benefit. The biggest thing I felt was an immense existential dread lifting from me. It's like the world millennials were promised when we were young actually exists - working on meaningful things with mental space to breath.

There's too much that can possibly be said of this, but up until now I genuinely thought there was only one way left and we were all doomed to fail, trying to pound sand into intractable problems. I somehow have hope in my life again.

dluan··on How China built its ‘Manhattan Project’ to rival the West in AI chips
It's wild to me that so many skeptical westerners who want to nitpick certain unproven technicalities, when the entire world only gets bits and pieces of the on the ground reality of China's progress, like the original Reuters article which was clearly fed information by insiders.

You should be living in the world of "China has successfully developed EUV and equivalent litho supply chain" and basing your decision making off of that.

dluan··on How China built its ‘Manhattan Project’ to rival the West in AI chips
Reunification in Taiwan has nothing to do with chips, and militarily PRC was able to do so a long time ago. The political will in PRC to "kill other Chinese" is zero.
dluan··on Gundam is just the same as Jane Austen but happens to include giant mech suits
You have to be more specific because "Eastern" here does not include Chinese thematic tropes.

Sun Wukong is the original "normal guy who grinds to greatness", which was the original plot of Dragonball before it turned more into Harry Potter (you are the chosen one).

dluan··on Gundam is just the same as Jane Austen but happens to include giant mech suits
I thought it was pretty well known that Gundam is a commentary on class and the effects of imperialist wars on normal people. The OG series didn't glorify violence and instead showed a lot of gratuitous civilian deaths, and most of the main characters are the poor-orphan-becoming-a-knight archetype.

Plus Jane Austen at the time was a sharp critique of English nobility and high class, but presenting it in a stylized and popular way.

dluan··on The fall of Labubus and the mush of modern internet trends
As a subculture dedicated to being in the know on certain things, HN commenters purposely showing theyre being out of touch on this specific subculture is pretty funny.

It's not that serious, I promise. When you were a kid you probably also had beany babies, furbies, crazy bones, magic cards, tamagotchis, tech decks, steel bearing yo-yos, or whatever else thing was a fad. Guess what, those were all made in China too.

dluan··on Over-regulation is doubling the cost
There are 100 million members of the party, and these people vote directly for their local representatives, who then go onto vote for the village, town, city, province, etc representatives, all the way up to the Standing Committee which includes Xi. There are 3000 members of the National People's Congress that directly selects the Standing Committee. In rural areas or special administrative provinces, often anyone can vote, including union members who aren't officially party members. Comparatively, in the 2024 US election, 150 million people voted. So there's roughly the same amount of votes happening.

Maybe you don't agree that not being able to pick the head of state is not a valid definition of democracy. In that case I'd argue that having a twice-indicted convicted felon is not valid democracy either. In any case, feel free to keep your version.

dluan··on Over-regulation is doubling the cost
This is incorrect. There are 9 parties. You are likely saying "well it's functionally a singe party system" yet you can't even read Chinese to understand what the policy positions of the different factions within the committees are.

dluan··on Over-regulation is doubling the cost
I was just in Hangzhou two days ago, and went through the Hangzhouxi train station. Needless to say it's utterly massive, straight out of a Star Trek scene, extremely efficient and clean. Construction was started in 2019, and finished in 2022. It cost $2.25bn. Hangzhou has 5 of these train stations, let alone one.

I'm convinced that every SV founder or neolib politician who writes these hit/think-pieces is getting their enemy entirely mixed up. China is massively bureaucratic and regulation heavy, and just by the scale of these projects, it's simply impossible to think that if you just loosen some rules and fly by your seat pants, you can build a 11 platform train station in 3 years. Again, this station is mind bogglingly massive.

The real answer is that China's regulatory loop is extremely short and small, where the government works very closely and reacts very quickly. You can talk to your regulator, even if you're a small startup working on a small hardware problem. Because every single community district has a CPC office, with representatives that can escalate things all the way up to the top. There's a clear chain of command, and throw in some guanxi to keep the gears greased up, things (problems, questions, hurdles) get to where they need to go. In the US, politicians don't work for their constituents, and even in the rare cases where they do (or have good intentions), they are up against other politicians who have ulterior agendas and their own goals. The machine thrashes against itself, not in a single direction. This is exactly the image of "democracy" in the the minds of the Chinese general public.

The problems described in OPs post are exactly the kind of thing China is good at tackling because their democratic system is actually built for this.
