Don't Anthropic and OpenAI both offer the same thing built in? What are the difference with this service?

>they do not want to pay a subscription.

This is wrong in 2026. Lots of people want to pay. See: TFA

What they don't want is and _still_ see ads, get hassled by needy marketing emails. See: TFA

If you're saying "we're gonna show you ads and datamine you because you're getting it free", then when I do pay, you have to take that stuff out. Try to have your cake and eat it too = sub canceled, adblock on, ad nauseam enabled.

That's how it has to be. Volunteer community doesn't have the bandwidth to make everything maximally user friendly. Users have to do their share too, by accepting the responsibility to learn about their system. Otherwise the model isn't feasible. If you want an appliance experience where you have zero responsibility as a user, you can go to the commercial vendor, but they will also have power over you and abuse it.

Linux is indeed for people who can love linux. For people who don't like computers, there's basically no solution.

There's a spectrum of writing, corresponding to supply/demand or push/pull. The article is giving advice for oversupplied writing, where the audience doesn't really want to hear you, and you're trying to badger it into reading it anyway - typically, for some sort of personal gain (getting an interview, making a sale, promoting a political cause). Yes, attention hacking is important in this case.

There is also a writing where people are looking for the information, and they are showing up at your door because they already care. Presumably you wrote, because you saw the open question, and want to try answering it. History books, encyclopedias, classic literature by dead people, falls under this. Ironically, so does the example of Venice - you would read about Venice if you were already curious; there is little profit in "making someone care" about Venice otherwise. An attention grabby style would be forced and counterproductive in this.

This was a very confusing article, full of filler. I couldn't stand to read the "detective story" style.

Sounds like the technique is for high-dimensional ellipsoids. It relies on putting them on a grid, shrinking, then expanding according to some rules. Evidently this can produce efficient packing arrangements.

I don't think there's any shocking result ("record") for literal sphere packing. I actually encountered this in research when dynamically constructing a codebook for an error-correcting code. The problem reduces to sphere packing in N-dim space. With less efficient, naive approaches, I was able to get results that were good enough and it didn't seem to matter for what I was doing. But it's cool that someone is working on it.

A better title would have been something like: "Shrink-and-grow technique for efficiently packing n-dimensional spheres"

>You can give a quick explanation in terms they understand, which makes your job sound easy and makes them wonder how anybody gets paid to do it.

What is the problem with this?

Most jobs, when simplified, sound like "anybody can do it". I think it's generally understood among adults who have been in the workforce that, no, in fact anybody cannot do it.

If we assume 100 colonists on the ship, with 10 tons of mass per person, accelerating to 0.2c over 2 ly and then back down, the energy required is quite substantial. Multiple centuries of the total output of the whole planet.

With Alpha Centauri being only 4 light years away, interstellar travel seems almost feasible. But then you consider all the inconvenient details, and realize such a journey would have to take hundreds, maybe thousands or even more years on top of some incredible advances in rocket tech.

If you go to something like Trappist (40 ly) at 0.01c (very optimistic), it's not just that everyone you know will be dead when you arrive. Your entire nation will have disappeared to the sands of time. The landfall announcement you send back will be incomprehensible because of language shifts, and you won't live to see the reply. Meanwhile, such a trip would be an enormous investment, requiring multiple nations to bankrupt themselves, with no hope of even surviving to see the outcome.

With that, it's very hard to imagine interstellar travel being feasible with our current understanding. There would have to be something like FTL travel or wormhole. The only "realistic" development, (much) better engines that can do 0.1c, would not actually change much.

Usually, animals move around while digesting. They don't just eat the food, immediately digest it, and poop on the spot like a cartoon.

>Most of this carnivorous botany is small, but the diversity of different trapping mechanisms raises an evolutionary question.

Isn't the obvious conclusion that: 1. There are many peaks in the fitness hypersurface for plants that correspond to meat eating 2. The peaks have smooth gradients at the outskirts 3. All peaks are minor local maxima

1 is because low nitrogen alone is not enough to make carnivory a net positive contributor to fitness. You need additional factors to make the gradient positive to begin with. That means the peaks (niches) are random and narrow.

3 is because carnivory implies an arms race against prey defenses, competing scavengers, and competing predators. Specialist animals are at a large advantage against plants, especially if meat is still a side dish to sunlight.

To me the interesting question is 2 - most plants don't digest animals at all, so how does this begin to evolve?

Wouldn't animal scavengers pick the carcass clean long before it rots?

RWD on an electric truck, lol. What a joke.

It seems performative. They remove a bunch of stuff nobody ever complained about, like paint or radio. Meanwhile it still has an app and it's still electric with pitiful range. The goal isn't to actually fix the car market, but provide a sort of self-flagellation experience so people can feel good about suffering with no radio, no ac, no auto windows... And I doubt they will reach that goal, sounds more like some kind of investor scam. With all these controversial design decisions they can brag to investors it's "making waves on popular platforms like hn".

The most interesting point in this is that people don't/can't fully utilize LLMs. Not exposing the system prompt is a great example. Totally spot on.

However the example (garry email) is terrible. If the email is so short, why are you even using a tool? This is like writing a selenium script to click on the article and scroll it, instead of... Just scrolling it? You're supposed to automate the hard stuff, where there's a pay off. AI can't do grade school math well, who cares? Use a calculator. AI is for things where 70% accuracy is great because without AI you have 0%. Grade school math, your brain has 80% accuracy and calculator has 100%, why are you going to the AI? And no, "if it can't even do basic math..." is not a logically sound argument. It's not what it's built for, of course it won't work well. What's next? "How can trains be good at shipping, I tried to carry my dresser to the other room with it and the train wouldn't even fit in my house, not to mention having to lay track in my hallway - terrible!"

Also the conclusion misses the point. It's not that AI is some paradigm shift and businesses can't cope. It's just that giving customers/users minimal control has been the dominant principle for ages. Why did Google kill the special syntax for search? Why don't they even document the current vastly simpler syntax? Why don't they let you choose what bubble profile to use instead of pushing one on you? Why do they change to a new, crappy UI and don't let you keep using the old one? Same thing here, AI is not special. The author is clearly a power user, such users are niche and their only hope is to find a niche "hacker" community that has what they need. The majority of users are not power users, do not value power user features, in fact the power user features intimidate them so they're a negative. Naturally the business that wants to capture the most users will focus on those.

It's not really YAGNI if you need it to debug, is it?
