Quotes

A parasol twirled Under midsummer’s rays Men’s eyes towards the clouds And yours toward the ground ...Embroideries and golds Insatiable desire Incenses at moonlight In Fuji’s twilight shadow Glances cloaked in silk A fan, a kimono Eyes and lips open Heart steeled Death Death to your son’s cousin Death Death to all opposition Smiling Half-pursed lips Stifling a giggle The glee of a young girl...

We had to exclude [dead] and eventually even just [flagged] posts from the public API because many third-party clients and sites were displaying them as if they were regular posts. […] IMO this issue is existential for HN. We've spent years and so much energy trying to find a balance between openness and human decency, a task which oscillates between barely-possible and simply-doomed, so the idea that anybody anywhere sees anything labeled "Hacker News" that pours all the toxic waste back into the ecosystem is physically painful to me.

Today's software ecosystem evolved around a central assumption that code is expensive, so it makes sense to centrally develop and then distribute at low marginal cost. If code becomes 100x cheaper, the choices no longer make sense! Build-buy tradeoffs often flip. The idea of an "app"—a hermetically sealed bundle of functionality built by a team trying to anticipate your needs—will no longer be as relevant. We'll want looser clusters, amenable to change at the edges. Everyone owns their tools, rather than all of us renting cloned ones.

"What do you see when you look in the Mirror [of Erised]?" "I? I see myself holding a pair of thick, woollen socks." Harry stared. "One can never have enough socks", said Dumbledore. "Another Christmas has come and gone and I didn’t get a single pair. People will insist on giving me books."

My preferred approach in many projects is to do some unit testing, but not a ton, early on in the project and wait until the core APIs and concepts of a module have crystallized. At that point I then test the API exhaustively with integrations tests. In my experience, these integration tests are much more useful than unit tests, because they remain stable and useful even as you change the implementation around. They aren’t as tied to the current codebase, but rather express higher level invariants that survive refactors much more readily.

You can think of the attention mechanism as a matchmaking service for words. Each word makes a checklist (called a query vector) describing the characteristics of words it is looking for. Each word also makes a checklist (called a key vector) describing its own characteristics. The network compares each key vector to each query vector (by computing a dot product) to find the words that are the best match. Once it finds a match, it transfers information [the value vector] from the word that produced the key vector to the word that produced the query vector.

The way you make users understand your program model is with metaphors. When you make things look, feel, and most importantly, behave like things in the real world, users are more likely to figure out how to use the program, and the app will be easier to use. When you try to combine two very dramatically different real-world items (email and appointments) into the same kind of thing in the user interface, usability suffers because there’s no longer a real-world metaphor that applies.

All these generative models point to the same big thing that’s about to alter culture; everyone’s going to be able to generate their own custom and subjective aesthetic realities across text, video, music (and all three) in increasingly delightful, coherent, and lengthy ways. This form of fractal reality is a double-edged sword – everyone gets to create and live in their own fantasies that can be made arbitrarily specific, and that also means everyone loses a further grip on any sense of a shared reality. Society is moving from having a centralized sense of itself to instead highly individualized choose-your-own adventure islands, all facilitated by AI. The implications of this are vast and unknowable. Get ready.

It is a profound truth—realized in the nineteenth century by only a handful of astute biologists and by philosophers hardly at all (indeed, most of those who held and views on the matter held a contrary opinion)—a profound truth that Nature does not know best; that genetical evolution, if we choose to look at it liverishly instead of with fatuous good humor, is a story of waste, makeshift, compromise and blunder.

Here's what I think is happening: AI-assisted coding is exposing a divide among developers that was always there but maybe less visible. Before AI, both camps were doing the same thing every day. Writing code by hand. Using the same editors, the same languages, the same pull request workflows. The craft-lovers and the make-it-go people sat next to each other, shipped the same products, looked indistinguishable. The motivation behind the work was invisible because the process was identical. Now there's a fork in the road. You can let the machine write the code and focus on directing what gets built, or you can insist on hand-crafting it. And suddenly the reason you got into this in the first place becomes visible, because the two camps are making different choices at that fork.

For resiliency, the DNS Enactor operates redundantly and fully independently in three different Availability Zones (AZs). [...] When the second Enactor (applying the newest plan) completed its endpoint updates, it then invoked the plan clean-up process, which identifies plans that are significantly older than the one it just applied and deletes them. At the same time that this clean-up process was invoked, the first Enactor (which had been unusually delayed) applied its much older plan to the regional DDB endpoint, overwriting the newer plan. [...] The second Enactor's clean-up process then deleted this older plan because it was many generations older than the plan it had just applied. As this plan was deleted, all IP addresses for the regional endpoint were immediately removed.

The arc of TF2 is something that's probably familiar to a lot of amateur developers or designers. When we got here the first thing we built was overly complex, very hard core, almost impenetrable to anyone who wasn't familiar with FPSs in general. And as we found as we played it, wasn't more fun because of it.

To sum up: it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence. If a man, holding a belief which he was taught in childhood or persuaded of afterwards, keeps down and pushes away any doubts which arise about it in his mind, purposely avoids the reading of books and the company of men that call into question or discuss it, and regards as impious those questions which cannot easily be asked without disturbing it—the life of that man is one long sin against mankind. ..."But", says one, "I am a busy man; I have no time for the long course of study which would be necessary to make me in any degree a competent judge of certain questions, or even able to understand the nature of the arguments." Then he should have no time to believe.

It's hard to overstate the value of LLM support when coding for fun in an unfamiliar language. [...] This example is totally trivial in hindsight, but might have taken me a couple mins to figure out otherwise. This is a bigger deal than it seems! Papercuts add up fast and prevent flow. (A lot of being a senior engineer is just being proficient enough to avoid papercuts).

What are they burning, what are they burning, Heaping and burning in a thunder-gloom? Now is the time for the burning of the leaves. They go to the fire; the nostril pricks with smoke Wandering slowly into a weeping mist. Brittle and blotched, ragged and rotten sheaves! A flame seizes the smouldering ruin and bites On stubborn stalks that crackle as they resist. The last hollyhock’s fallen tower is dust; All the spices of June are a bitter reek, All the extravagant riches spent and mean. All burns! The reddest rose is a ghost; Sparks whirl up, to expire in the mist: the wild Fingers of fire are making corruption clean. Now is the time for stripping the spirit bare, Time for the burning of days ended and done, Idle solace of things that have gone before: Rootless hope and fruitless desire are there; Let them go to the fire, with never a look behind. The world that was ours is a world that is ours no more. They will come again, the leaf and the flower, to arise From squalor of rottenness into the old splendour, And magical scents to a wondering memory bring; The same glory, to shine upon different eyes. Earth cares for her own ruins, naught for ours. Nothing is certain, only the certain spring.

There’s a funny irony in “tell your story” and “speak your truth”, in that those two things are fundamentally at odds with each other. Stories and narratives aren’t, and can’t be, the truth of our actual lived experiences. Real lives don’t follow the structures of narrative, they don’t move in linear tidy sequences of causes and actions and effects and consequences. Real lives are big jumbled messes that are almost impossible to make real sense of, and the act of imposing a narrative on them, sorting out our “life story”, is always an act of editing.

We write a lot of JavaScript at Basecamp, but we don’t use it to create “JavaScript applications” in the contemporary sense. All our applications have server-side rendered HTML at their core, then add sprinkles of JavaScript to make them sparkle. [...] It allows us to party with productivity like days of yore. A throwback to when a single programmer could make rapacious progress without getting stuck in layers of indirection or distributed systems. A time before everyone thought the holy grail was to confine their server-side application to producing JSON for a JavaScript-based client application.

The strong manly ones in life are those who understand the meaning of the word patience. Patience means restraining one's inclinations. There are seven emotions: joy, anger, anxiety, adoration, grief, fear, and hate, and if a man does not give way to these he can be called patient. I am not as strong as I might be, but I have long known and practiced patience. And if my descendants wish to be as I am, they must study patience.

I have met people who exaggerate the differences [between the morality of different cultures], because they have not distinguished between differences of morality and differences of belief about facts. For example, one man said to me, "Three hundred years ago people in England were putting witches to death. Was that what you call the Rule of Human Nature or Right Conduct?" But surely the reason we do not execute witches is that we do not believe there are such things. If we did-if we really thought that there were people going about who had sold themselves to the devil and received supernatural powers from him in return and were using these powers to kill their neighbours or drive them mad or bring bad weather, surely we would all agree that if anyone deserved the death penalty, then these filthy quislings did. There is no difference of moral principle here: the difference is simply about matter of fact. It may be a great advance in knowledge not to believe in witches: there is no moral advance in not executing them when you do not think they are there. You would not call a man humane for ceasing to set mousetraps if he did so because he believed there were no mice in the house.

The researchers found that simply having the doctors and nurses in the I.C.U. make their own checklists for what they thought should be done each day improved the consistency of care to the point that, within a few weeks, the average length of patient stay in intensive care dropped by half.

the Meta controlled, AI-generated Instagram and Facebook profiles going viral right now have been on the platform for well over a year and all of them stopped posting 10 months ago after users almost universally ignored them. [...] What is obvious from scrolling through these dead profiles is that Meta’s AI characters are not popular, people do not like them, and that they did not post anything interesting. They are capable only of posting utterly bland and at times offensive content, and people have wholly rejected them, which is evidenced by the fact that none of them are posting anymore.

How far this unexpected distinction can be rated among the happy incidents of life, I am not yet able to determine. Its first effect has been to make me anxious lest it should fix the attention of the public too much upon me, and as it once happened to an epic poet of France, by raising the reputation of the attempt, obstruct the reception of the work. I imagine what the world will expect from a scheme, prosecuted under your Lordship's influence, and I know that expectation, when her wings are once expanded, easily reaches heights which performance never will attain, and when she has mounted the summit of perfection, derides her follower, who dies in the pursuit.

I saw the business of writing for what it truly was and is to me. It is your penance for not being lucky. It is an attempt to reach others and to make them love you. It is your instinctive protest, when you find you have no voice at the world’s tribunals, and that no one will speak for you. I would give my entire output of words, past, present, and to come, in exchange for easier access to the world, for permission to state "I hurt" or "I hate" or "I want." Or, indeed, "Look at me." And I do not go back on this. For once a thing is known it can never be unknown. It can only be forgotten. And writing is the enemy of forgetfulness, of thoughtlessness. For the writer there is no oblivion. Only endless memory.

The religious life does not depend on the dogma that the world is eternal or not, infinite or not, the soul and body identical or not, saints live after death or not...Those profit one not, nor have to do with the fundamentals of religion, nor extinguish passion. They do not lead to supreme wisdom & Nirvana.

I’ve been watching junior developers use AI coding assistants well. Not vibe coding—not accepting whatever the AI spits out. Augmented coding: using AI to accelerate learning while maintaining quality. [...] The juniors working this way compress their ramp dramatically. Tasks that used to take days take hours. Not because the AI does the work, but because the AI collapses the search space. Instead of spending three hours figuring out which API to use, they spend twenty minutes evaluating options the AI surfaced. The time freed this way isn’t invested in another unprofitable feature, though, it’s invested in learning. [...] If you’re an engineering manager thinking about hiring: The junior bet has gotten better. Not because juniors have changed, but because the genie, used well, accelerates learning.

[On a startup using machine learning to encourage people to get addicted to apps] This technology is so unethical it needs to be criminalized globally, before it evolves into a Fermi Paradox solution... and I generally DON'T think banning technologies is a good idea. But this is like a neuroscience homebrew dirty nuke.

But this much is clear: Facebook knew all along. Their own employees were desperately trying to get anyone inside the company to listen as their products radicalized their own friends and family members. And as they were breaking the world, they had an army of spokespeople publicly and privately gaslighting and intimidating reporters and researchers who were trying to ring the alarm bell. They knew all along and they simply did not give a shit.
