nkoren··on Nukeproof: Manifesto for European Data Sovereignty
I absolutely appreciate and agree with the sentiment, but can't figure out what the proposition actually is. The thesis seems to be: "Here's a problem. We want to solve it." Aaaaaaaaaaaand ... that's it. Exactly how are you going to solve it? Or, if "exactly" is too much of an ask, could we at least have a "vaguely"? Seems like it needs more meat on the bones!
nkoren··on A giant ball will help this man survive a year on an iceberg
Agreed. There are mountains that don't survive getting crushed between two icebergs. If the sphere were made of solid tungsten, then okay, I'd buy it. Short of that, I have doubts.
nkoren··on China's first orbital booster landing attempt
Eh, they got further than New Glenn did on its first attempt, and it succeeded on its second. They obviously made it through re-entry / retropropulsion in one piece and with a stable attitude, which is an achievement in itself. Looks like an engine exploded at the start of the braking burn -- or in any case, they suddenly start combusting a whole lot of stuff that isn't methane. But that might just be a single point failure, and a whole lot had to go right for them to get this far. It's reasonable that they could succeed on their next attempt.
nkoren··on Inflatable Space Stations
Airship To Orbit is JP Aerospace, not Bigelow. It seems like an utterly bonkers and fairly implausible concept and I'm definitely not equipped to analyze its merits. But the JP team have some legitimate accomplishments in the rockoon world, and appear to be honest, hardworking people. Definitely not grifters. I've been following their work on ATO since they first announced it at a Space Access conference in ... 2003, I think? Still can't figure out whether it's real or not.
nkoren··on Jack Kerouac, Malcolm Cowley, and the difficult birth of On the Road
Personal anecdote time, which enough time has passed that it can finally be told.

About 30 years ago, a family came down from the mountains near San Luis Obispo to ask whether my mother could teach them piano. They were an unusual family -- a mother and a number of children; apparently their father wouldn't leave his homestead up in the mountains. The children were all homeschoooled. They were perhaps a bit raggedy, but all quite brilliant and free-thinking, and quickly became excellent piano players. Our family became friends with theirs, and eventually we were invited to visit their homestead up in the mountains.

The homestead was an off-grid hand-built house and working organic dairy farm, lovingly stuffed to the rafters with various arts and crafts, including a large collection of medieval-style musical instruments which the patriarch of the family, Hal, had built by hand. Hal was an enigma within an enigma: he refused to talk about his past, looked like a Santa-clause mountain man, wouldn't engage with the outside world in person, but was relentlessly curious about it -- able to keep up with conversations about the latest in politics and technology. He also had a keen interest in the archaeology of the upper Colorado plateau, and soon we were making trips to the Cal Poly library to check out the latest archaeology books on his behalf. One day, on a whim, we looked for his name in the index of one of those books, and that's when we found out that we already knew who he was.

Haldon Chase[1] had been at the absolute epicenter of the Beat movement. He was the one who introduced Allen Ginsberg to Jack Kerouac, and most of the other Beats to each other. He'd gone by pseudonym "Chad King" in "On the Road". At the time he didn't have a Wikipedia entry, and at the time all anybody knew is that he had vanished at some point. Of course my family felt privileged to know the rest of the story.

Thinking now about Hal's life, in the few retrospectives I've seen of it, he's framed as having rejected the whole Beat lifestyle. I'm not sure that's accurate. In many ways the life he managed to carve out for himself was the apotheosis of much of the beat philosophy: genuinely free-thinking, self-reliant, non-conformist, creative, and in his way, spiritual. All very Beat. What he certainly rejected was the the limelight. The publicity, the drama, the ego. He wanted absolutely nothing to do with any of that. So he managed to get away and just live a good (if unconventional) life. His kids have all gone on to live really good, non-messed-up lives as well.

So when reading stories about messed-up Beats and their messed-up kids, it's worth considering that there's a kind of anti-survivor-bias at play: where everything worked out, where the trauma didn't explode dramatically or get passed down the generations, you're probably not going to hear about it.

nkoren··on What Happened in 2007?
Not explicitly arguing against the thesis of the website, but showing trend lines which allegedly started in 2007 with data that starts in 2006 is... Not convincing.
nkoren··on American solar farms
Yes, it would be absolutely irrational and indefensible to block people from building solar farms where there is a straightforward commercial case for doing so. Unfortunately, "irrational and indefensible" is exactly what this administration is: https://www.theguardian.com/us-news/2025/oct/10/trump-offici...

nkoren··on Ask HN: Why does the US Visa application website do a port-scan of my network?
Hard to imagine that the US wouldn't be as paranoid, self-sabotaging, and bureaucratically inept as possible? </sarcasm>
nkoren··on The Life and Death of London's Crystal Palace (2021)
The dinosaurs are concrete, and date from 1852. That's 7 years before Darwin published On the Origin of Species, and 55 years before the invention of plastic. So they're a kind of amazing window into the pre-history of paleontology. Really great artefacts, well worth seeing.

Anyhow,hope you eventually got a better girlfriend.

nkoren··on A 1960s schools experiment that created a new alphabet
The standard joke is that English isn't actually a language: it's three languages stacked on top of each other wearing a trench coat, which go around beating up other languages and rifling through their pockets for loose vocabulary and spare grammar. This is funny because it's true.

Modern Italian, on the other hand, makes a modicum of sense because it was explicitly constructed during the 19th-century unification of Italy, when somebody had the bright idea that if you wanted to have a nation called "Italy", you should also have a language called "Italian" and it should make a modicum of sense. This is a memo which English has somehow never gotten.

nkoren··on A 1960s schools experiment that created a new alphabet
So if you want to remember how to spell "phone", you first have to remember "puh-hon-eh"? I'm not sure that'd be an improvement. How do you even make a phonetic word out of something like "rough"?

The problem will always be that that English has a lot more phonemes than it does letters, so a 1:1 mapping will never be possible. That said, I do think it would be a good idea to have a 1:1 correlation. Which is why everybody should just learn Esperanto instead.[1]

1: Joking.[2]

2: Well, mostly joking.

nkoren··on Hymn to Babylon, missing for a millennium, has been discovered
See my later reply to the parent comment, but basically, first there's the creation of the whole world and all the peoples in it, then there's the creation of the Garden of Eden and Adam and Even and so forth. The first is ascribed to "God", or "Elohim" in Hebrew -- a plural word which has recently been awkwardly recontextualized through a monotheistic lens, but probably originally meant "the gods" -- while the second is ascribed to the "LORD God", or "YHVH" in Hebrew -- a definitely specific God.
nkoren··on Hymn to Babylon, missing for a millennium, has been discovered
This is all absolutely correct. To amplify this point for people unfamiliar with it, the two creation stories are:

1. God separates the light from the darkness, the earth from the water, and creates all the plants and animals and peoples of the world.

2. The LORD God creates the garden of Eden, makes Adam from mud and Eve from his rib, plants a tree of knowledge and tree of life, etc.

Already there's a divergence: Adam is supposedly the first man in the second story, but in the first story, all the peoples of the world have already been created. But the more interesting divergence is in the name of the responsible God. This often flies over the head of readers in English, but notice that the first story isn't the "LORD God", just "God". This is because in Hebrew, the name of God in the first story is "Elohim", while in the second, it's "YHVH" -- a name too holy for Jews to pronounce, so they just say "Hashem" ("the name"), although if you're naughty you can say "Yahweh" or "Jehovah" or whatever. Why the difference?

A clue is that "Elohim" is a pluralised word in Hebrew. Once Judaism became fully monotheistic, this became interpreted as something like "The Wings of God" -- a sort of abstract all-encompassing Godly aura, rather than the pointed and personified manifestation of the divine, which is YHVH. But this is a bit of a tortured post-rationalisation, and isn't explicitly supported by the text. It's much more straightforward to read "Elohim" as simply "the gods", which is probably how it was read when the text was first assembled, with a henotheistic YHVH text being appended to an earlier polytheistic text.

Even the first commandment -- "I am YHVH, your God, and you shall have no other Gods before me" -- reads better as a henotheistic rather than a monotheistic text. It doesn't say there are no other gods. It pretty strongly implies the opposite. It just says that the other gods aren't for you.

nkoren··on Is TfL losing the battle against heat on the Victoria line?
Indeed. At 3C in London, the humidity seeps into every pore and settles into your bones. Riding a bike at 3C, unless you're wearing a balaclava and a ski mask, is an exercise in pure pain, as the wetness sublimating off your face has approximately the same effect on your facial nerves as being flayed.

Ok the other hand, -2C in London is crisp and invigorating and entirely preferable in every possible way.

nkoren··on A $20k American-made electric pickup with no paint, no stereo, no screen
Not a truck guy, but I like it. What I like the most is that it's not batshit fucking insane.

I recently visited America after a couple of years away, and spent a couple of weeks in California, driving from SF to LA. The thing which I found the most striking was the sheer insanity of the pickup trucks that were absolutely everywhere. These things were true Idiocracy-class monster trucks, which are clearly lethal to operate in any environment which includes pedestrians. In some cases, my five-year-old's head barely reached the bumper, and my wife's head didn't clear the hood. And these were highly-polished, un-dented behemoths that had clearly never seen a dirt road in their lives. The whole thing is clearly all about aesthetics and identity politics. Absolutely revolting.

(If you haven't visited the US recently, I think it's almost impossible to appreciate how obscene the phenomena is. 10 years ago, trucks were far more restrained, but could still do everything they needed to do. 30 years ago, trucks were fully half the size, but could still carry the same-size loads and do honest work. There's honestly no possible justification for their corpulent growth.)

Anyhow, this thing looks like it can do honest work without killing everyone who crosses its path. I really appreciate that. I hope it starts a trend.

nkoren··on Cursor IDE support hallucinates lockout policy, causes user cancellations
I've been doing AI-assisted coding for several months now, and have found a good balance that works for me. I'm working in Typescript and React, neither of which I know particularly well (although I know ES6 very well). In most cases, AI is excellent at tasks which involve writing quasi-custom boilerplate (eg. tests which require a lot of mocking), and at answering questions of how I should do _X_ in TS/React. For the latter, those are undoubtedly questions I could eventually find the answers on Stack Overflow and deduce how to apply those answers to my specific context -- but it's orders of magnitude faster to get the AI to do that for me.

Where the AI fails is in doing anything which requires having a model of the world. I'm writing a simulator which involves agents moving through an environment. A small change in agent behaviour may take many steps of the simulator to produce consequential effects, and thinking through how that happens -- or the reverse: reasoning about the possible upstream causes of some emergent macroscopic behaviour -- requires a mental model of the simulation process, and AI absolutely does _not_ have that. It doesn't know that it doesn't have that, and will therefore hallucinate wildly as it grasps at an answer. Sometimes those hallucinations will even hit the mark. But on the whole, if a mental model is required to arrive at the answer, AI wastes more time than it saves.

Yes. They added greek letters to make themselves sound smart. But the terms cancel out and are therefore meaningless.

nkoren··on Firefly ‘Blue Ghost’ lunar lander touches down on the moon
Excuse me?

I'm familiar with the Mariner camera. It's pretty fascinating. There obviously no way to return film from a Mars flyby, so they had to take a digital approach. But the technology was so crude in 1965 that they literally had to paint the "digital" images by hand in order to get a visual output. It's a fascinating story.

https://science.nasa.gov/resource/first-tv-image-of-mars-han...

Suffice it to say that this technique has essentially no relation to today's digital cameras, apart from using electrons or something. The Apollo missions did not use digital cameras; they used film, which could produce superb high-resolution images, provided you could return it to Earth.

You can actually learn things in this forum, if you listen to people who know what they're talking about.

Here's what Firefly uses: https://en.wikipedia.org/wiki/Digital_photography

Hopefully you can see that from a raw tech level, there's practically no overlap between those things at all. The technology has moved on _completely_.

nkoren··on Does X cause Y? An in-depth evidence review (2021)
Yeah, sadly, I think it's worth having "ulterior motives" on the list.

One of the first time I got interested in reading medical studies was when I saw a bunch of headlines announcing that a randomized controlled trial had proved that echinacea was ineffective for treating respiratory problems. This surprised me, because I'd always been a dogmatic drinker of echinacea tea whenever I had a cold, and had thought that it helped. But then again, I come from a culture of damn dirty hippies, so I was open to being wrong about it. Rather than rely on the headlines, I decided to dig up the study itself.

Here's what the study actually found: that rubbing an echinacea-infused ointment on your wrists has no effect on respiratory health.

Er... yeah, no shit, Sherlock. Literally nobody uses echinacea that way. You've just falsified a total straw-man of a hypothesis, and based on the number of headlines generated off the back of this, I think it's reasonable to presume there was some kind of funded apparatus for disseminating that bogus result.

Ever since then, I've learned not to trust the headlines when it comes to trials, reserving judgment until I've looked at the methodology. When I do, a lot come up short.
