> […] a small dish of 1 m^2 will catch roughly 1 photon per second. Given that the datarate is 40 bits/second, it's physically plain impossible to receive the signal with a small dish.

Do you just mean plain impossible with the specific type of system used with Voyager, or are making a general argument that all systems that have a 1 photon/second rate cannot carry 40 bits/second of data?
To be fair, many many people die in car accidents every day. Yes, self driving car crashes are still newsworthy but you are up against a baseline that’s pretty bad.

On the other hand, virtually no one dies from laundry, that I’m aware of. So the reaction to a single accident might be quite different.

It’s supposedly a “fallacy” and “arbitrary” and yet, 26 years after this prediction, the growing languages right now are Rust (compiled, statically typed systems language) and Python (dynamically typed glue code written by non-CS mathematics people).

My personal preference is to 1) treat linux servers as appliances and stop letting people login, 2) use containers, MACs, MCS and other such isolation tailored for specific services, 3) network ACL and segmentation up the wazoo, 4) MFA access control and 5) encrypt all the things.

If you are willing to relinquish copyright claims on your work, for example by including a copyleft statement in the book’s preface, an organization like Project Gutenberg may be willing to host it, ostensibly in perpetuity. Other considerations are whether the book can stand alone as text-only, or will it rely on additional media to convey its message to the reader?

Hey HN,

I’m Alex, and I’ve been using ChatGPT daily for work—content creation, marketing, automation—you name it. But honestly, it wasn’t saving me as much time as I’d hoped. I’d spend hours tweaking prompts and reworking outputs just to get what I needed.

After months of trial and error, I started creating my own prompts—ones that actually worked for real-world problems. I kept building and refining them, and eventually ended up with a collection of over 2,000 prompts that I now call the ChatGPT Mega-Prompts Bundle.

This bundle covers things like:

Writing content quickly (emails, ads, blogs).
Automating boring tasks (reports, onboarding).
Generating new ideas (lead gen, SEO strategies).
At first, it was just for me, but when I shared it with friends and my team, the feedback was crazy positive. They were saving hours, getting better results, and relying less on trial and error.

Now I’m launching it publicly, and I’d love your thoughts. If you’ve ever struggled to get ChatGPT to do exactly what you need, this might help.

Would love to know:

What’s your biggest frustration when using ChatGPT?
What kind of prompt would save you the most time?
Here’s the link if you want to check it out: ChatGPT Mega-Prompts Bundle

Thanks for reading, and I’d love any feedback or questions. This community has always been a huge inspiration for me, and I’m excited to share what I’ve built!
I mean, it's a pretty straightforward stance to understand, if not sympathize. If you pay taxes in Russia, your efforts directly support the war in Ukraine. You can have all sorts of arguments about choice and will, but this underlying truth remains the same.
Yeah, I can't even press and hold to open the image in a new tab (Android, Firefox).

He caveats this in the post, so he's not really dichotomizing.

IIUC, he implores educators to optimize for productive "workout" rather than fun. From my point of view, "workouts" must be rewarding on average, but need not be fun.
Sure, what you said is somewhat true, but you have seemingly misunderstood one key aspect here. They simply do not have enough training data to fold all possible laundry. If there was a way to fine-tune the robot on your own clothes, then it would be able to do your laundry just fine.

You're under the mistaken impression that this is just a scripted demo built around learning directly from teleoperation as was the case with mobile aloha. The VLA model here is capable of more generalization than you are willing to admit.
And then what, conclude that a useless action to delay progress is somehow good and allows you to feel better about yourself and superior to others using self-checkout while doing absolutely nothing? If that's the outcome of "classic education" I think you didn't do it right.
The map kind of does. It's really nice to just click on different dots and see different cities with no latency or page load. I think the right way to implement this is as an SPA with `history.push` for shareable URLs.
Word of caution regarding that kind of advice:
It is okay to read those helpers, to try them out and so on, but the surest way to write a totally bland story is to follow these narration formulae to the dot. You should always read them as "if nothing else helps use this"-type of advice.

That doesn't mean you could totally write a meaningful impacting story that follows that pattern, it just means if you have the problem of what to write, it is probably misleadingnyou into writing crap.

So my advice (as a MA of Arts who studied film and did their own writing) would be to read all of these helpers, extract the narrative advice from them and then write freely without following any simplistic formula that everybody and their dog has seen a million times in thousand low budget television series.

Or better: If you want to write good stories, instead of reading these "How to tell a story"-books take your favourite stories and analyze them meticulously: What are the major beats of the story? How does the story interact with the setting? How are figures introduced? What perspective is the story told from (and does that change throughout the story — if yes why)? Which part did impact you the most? Why did they impact you? What was used to create that impact? Which parts appeared to be just ornamental and without narrative function? What would happen if you left them out? And many more questions.

Do that with your ten favourite stories, series, films, theatre plays or whatever and you will probably learn more than in all of those books combined. And more important: You will do the thinking and it will give you story lessons that are relevant to material you like.

As my prof once said: the crows over Van Goghs field serve no direct function yet they are part of the picture, art does not need to be formulaic and it does not need to explain itself.
The underlying real goal is to have sex with the robots, just as the internet was going to be the gateway to all known information but instead is for porn.
> Is the solution really to replace even more workers by capital, or do we have an issue with how we measure value that we should fix first?

I have more faith in our ability to solve world peace and AGI than I do in us getting to a more objective way to measure value that everyone can agree and adhere to.
"should be effortful" and "should not be fun" are not opposites -- they aren't even related. Most people who "reach the top" of particular domains do so because they get enjoyment out of the required practice.

There are also lots of valuable intellectual tasks that appear more fun than effortful at face value. Watching talks at conferences springs to mind.

Show HN: HEVCut – iPhone app to save iCloud storage by compressing videos
Hey HN!

I created HEVCut, an iOS app that helps save iCloud storage by compressing videos into HEVC format with optimized metadata. It’s a straightforward solution for reducing video file sizes significantly (up to 50% or more), which speeds up load times and keeps quality high. I built it after struggling to manage my iCloud storage, especially with videos, and wanted something that didn’t rely on complex settings or third-party cloud services.

How It Works:
HEVCut performs local re-encoding to HEVC (H.265) while optimizing metadata. By default, it reduces resolution to Full HD for even smaller sizes, but you can adjust settings to maintain the original resolution. This local processing reduces storage usage and improves video loading without sacrificing quality.

Core Features:
• Instant Storage Savings: Reclaim space by shrinking video files directly on your iPhone.
• One-Tap Compression: Easy to use—just select a video and compress.
• Local, Private Processing: All compression happens on the device, not in the cloud.
• Adjustable Resolution: Default to Full HD for better compression, with the option to keep the original resolution if needed.

I’d love any feedback from the HN community or ideas on other features to add. Happy to answer questions or discuss the technical challenges I faced. Thanks for checking it out!

Is it "theft" if the people living there sell their natural resources?

There's a huge amount of injustice in the world. The Saudi regime is awful, too. You're not going to convince me that Assad is a great guy, but also I'm not in charge of US foreign policy and my side just lost bigly.

You'll probably get the chance to see what an isolationist US looks like. Trump's impulses are to leave everyone in the mideast to their own devices and it's hard to even say he's wrong.
The fun needs to come from the intrinsic motivation of the learner, not the content.

Good quality learning materials can be fun if you want to learn — or miserable if you don’t.

I learn way more when I’m personally driven than if it feels like “I have to.” But that’s me.
I trust an ai model more than remote humans.
> Where did the economies get a boost when women joined the labor force? In Germany the post-war economic miracle happened mostly without them.

I have a "hobbyist conjecture" that I'd love feedback on from people familiar with economics. Simply put, the idea is this: if you were to give every human around the world a million dollars (imagine this is easy and feasible), prices would inevitably rise. The poorest might experience some improvement in their standard of living, but not as much as one might expect. This effect seems to go beyond inflation alone. My intuition is that prices ultimately adjust based on social structures and expectations.

Similarly, we see a unique economic advantage in many dual-income gay couples who, statistically, achieve higher standards of living. Often, this is partly because fewer have children, which shifts financial priorities and spending capacities.
> It doesn't have to be actively not fun either, but the primary feeling should be that of effort.

Karpathy clearly wrote something different that what you say he wrote.
cute post, but get off twitter and talk to a real human being and most folk did not and do not really care about "woke" ism as you imply. its simply not really an issue as much as rightwing media blows it up to be.

people are still feeling the residual effects of the economy. they felt that and decided they wanted change. not to mention Harris had a 3 month ramp up, and people didn't know her.

twitter was filled with "woke" around 2016 and 2020 by the way; Americans still gave the Democrats the popular vote.
Because you can just have actual local people do it right there and then? The point of a robot is to not interact with other people, presumably they will be much more expensive than having someone come over for a few hours a week to clean - the whole appeal is there's no other human involved to coordinate or be nice to.
strikingly good observation, as another minority Canadian
i made a similar reply, linking to the ideas of flow state etc [1]. i dont know why you'd chase the feeling of effort, surely you'd avoid the feeling of effort where possible without reducing learning

Just to clarify, I'm asking where to host a static page that would be a modified introduction, addendum, errata, "if you like this try these", "The author died by wooden badger attack", etc

Not the entire book. I wouldn't have to copyleft the entire thing, right?

My current static page is just an "I like this book, please give me this free thing and put me on a mailing list" kind of thing. But that's not really the point. The point is "how can I use static pages, presumably the thing the internet was built for, to put a few pages of extra material on the book and perhaps give links for folks to follow if they're interested in the topic?"

Traditionally, you'd issue a new edition with such information, but that seems like a hella work and expenditure, and small stuff like this should be the kind of thing you'd be able to stick somewhere online, if nothing else as a parking spot until you eventually publish a new edition.

I wonder if the Internet Archive would be interested in this kind of archival.

Thomas Seyfried is a bit of a quack. He believes a keto diet beats chemo for almost all cancers.

https://sciencebasedmedicine.org/ketogenic-diets-for-cancer-...

> Seyfried, in my readings, appears all too often to speak of “cancer” as if it were a monolithic single disease. As I’ve pointed out many times before, it’s not. Indeed, only approximately 60-90% of cancers demonstrate the Warburg effect.

> Dr. Seyfried presents mouse studies that are interesting and suggestive that there might be something to this whole ketogenic diet thing, at least in brain tumors, such as this one. However, this is what we in the oncology biz would call pretty preliminary data, worthy of further investigation but not supporting the grandiose claims that Dr. Seyfried makes.

> Irritatingly, during the same talk, Dr. Seyfried refers to having done a “biopsy” on the GBM when the case report clearly says that the patient underwent a partial excision of the temporal pole with incomplete debulking of the tumor, which is a different thing.
> ...
> He also heaps scorn on the hospital for insisting that the patient undergo standard of care therapy, clearly demonstrating that he has no understanding of clinical trial ethics.

> This brings me back to the question of whether cancer is a metabolic disease or a genetic disease, the answer to which I promised early on. The likely answer? It’s both! Indeed, a “chicken or the egg” argument continues about whether it is the metabolic abnormalities that cause the mutations observed in cancer cells or whether it is the mutations that produce the metabolic abnormalities. Most likely, it’s a little of both, the exact proportion of which depending upon the tumor cell, that combine in an unholy synergistic circle to drive cancer cells to be more and more abnormal and aggressive. Moreover, cancer is about far more than just the genomics or the metabolism of cancer cells. It’s also the immune system and the tumor microenvironment (the cells and connective tissue in which tumors arise and grow). As I’ve said time and time and time again, cancer is complicated, real complicated. The relative contributions of genetic mutations, metabolic derangements, immune cell dysfunction, and influences of the microenvironment are likely to vary depending upon the type of tumor and, as a consequence, require different treatments. In the end, as with many hyped cancer cures, the ketogenic diet might be helpful for some tumors and almost certainly won’t be helpful for others. Dr. Seyfried might be on to something, but he’s gone a bit off the deep end in apparently thinking that he’s found out something about cancer that no one else takes seriously—or has even thought of before.

The most surprising thing I learnt from the past 5 years of full-time teaching both complete beginners and experienced programmers is this:

The main barrier to learning, for most people, is emotional, not intellectual.

Because of that, I disagree with most of what Karpathy wrote here.
I got myself this perfect clothes folding robot about 8 years ago when I decided I would not fold or iron clothes ever again. Two useless activities forever gone from my life. There's more things like this around the house but folding and ironing are 100% useless. I pick the clothes from the rack, they come kinda folded in half but I don't even try, and all get dumped into drawers. I never lack space because I'll buy clothes only upon throwing out clothes, so the bigger volume of the clothes doesn't make a difference in storage space either.

One key feature of learning is that it must involve some form of failure - at least in the sciences that HN is typically involved in. It is impossible to fail at watching a video, but it is possible to fail at deriving a formula yourself on a piece of paper, or at writing a program that is supposed to achieve some goal. The failure and subsequent recovery is exactly where knowledge is gained. This is perhaps why writing code is so much fun, the failure-recovery loop is very short.
Rust encodes far more information into source code than most languages, so it simply needs more syntax. I wouldn't say it's ugly (except macros, not sure what they were thinking there), there's just more of it.

Obviously if you remove lifetimes, types, references, etc. you're going to need less syntax.
I've often spent days figuring something out of spite rather than enjoyment. I think people have all sorts of motivations.
I don't think there's anything wrong with edutainment videos themselves, but you only really learn by doing, so they should facilitate that.

For example, my kids watch 'how to draw' videos on youtube, but they pause them every few seconds to copy the work, and then watch the explanations of how shadows work and so on.

There is some research on the effectiveness of videos in education, and how to use them properly (just watching is usually not enough), I'll try to dig up refs.
The circle and the segments is irrelevant to their argument.
>"Learning is not supposed to be fun. It doesn't have to be actively not fun either, but the primary feeling should be that of effort."

This idea is not wrong; however, I would rank 'persistence' (the willingness and ability to engage in learning down a specific path during many days, many weeks, many years, etc., etc.) as being higher in a "hierarchy of necessity for learning" than that of effort.

And I would rank 'unlearning' (the willingness and ability to "let go", become looser, less intransigent, entertain other opionions, other points of view, of what was previously learned down a specific path during many days, many weeks, many years, etc., etc.) as being higher still in a "hierarchy of necessity for learning" than even that of 'persistence'...

Finally, at the pinnacle of such a "hierarchy of necessity for learning" (should one ever exist!), I would rank 'Imagination' itself (AKA "the goal sought after", or more simply "The Goal!") as the highest tier, the pinnacle of such a "hierarchy of necessity for learning"...

(Also, if effort is to be made, it should be desired effort as opposed to undesired effort... i.e., effort coerced by other people and/or systems...)

But -- that's just me... :-)

Those above values are just mine and mine alone... one insignificant man's humble opinion...

Other people can and will have other "what's necessary for learning" hierarchies; other sets of values, as pertain to education as applied to themselves and groups of other people...
