I don't understand what you mean with your last paragraphs, but I disagree that there's a centralized moderation. Of all the social media I'm aware of, moderation is mostly distributed, and weighted. Instagram flagged posts go to "a team" to review, but they weigh that against the account and the content. Reddit moderation is per-subreddit. Facebook moderation is a combination of group moderators and site moderators.

In any case, I don't think moderation isn't a factor, because moderation is for commenters. Something like 90% of people just lurk. And that's where ads, influencers, comments, and everything else, are targeted.

How can we get more people viewing TikToks, or YouTube Shorts? How can we get more people to sub to our Patreon? How can we get more followers, or likes? This has nothing to do with moderation. It's the math of "what can we post that will make people "engage" with their eyeballs and their clicks?" That's what matters. Partly because eyeballs equal ad dollars; but also because eyeballs equal influence. The science of manipulation is getting you to see what I want you to see, and you coming back for more. The more you come back, the more you're part of my in-group.

Another example is astroturfing. I can't remember if it started for commercial or political gain, but the point is the same. Post some fake shit to make people believe there's a grassroots opinion, in order to get them to back it, with them assuming it's really a grassroots movement. Whether you're Vladimir Putin or DuPont, you benefit the same way: manipulation of public perception, through the science of social media disinformation.

I stand firm that there's no reason to write go in a .js file other than ragebaiting, especially with that "use" directive that clearly everyone is hating on Twitter at the moment (due to Vercel, etc)

To be clear I'm fine with importing .go from JS, it's the "go in file.js" thing I don't like.

As a security researcher, I am both salivating at the potential that the proliferation of TDD and other AI-centric "development" brings for me, and scared for IT at the same time.

Before we just had code that devs don't know how to build securely.

Now we'll have code that the devs don't even know what it's doing internally.

Someone found a critical RCE in your code? Good luck learning your own codebase starting now!

"Oh, but we'll just ask AI to write it again, and the code will (maybe) be different enough that the exact same vuln won't work anymore!" <- some person who is going to be updating their resume soon.

I'm going to repurpose the term, and start calling AI-coding "de-dev".

Depends on where you are in the world.

For the developed world, climate change will be annoying but not serious. The US may have to give up on Miami and New Orleans, and build seawalls for New York. Some crops may have to be grown further north. Some irrigation systems will need upgrades. More power will be needed for air conditioning. Those will not seriously damage a society. After all, right now the biggest problem in American agriculture is where to put all the excess soy and corn.

Countries in Asia with heavily populated big river delta areas of shallow slope are very vulnerable to small rises in sea level, because the coast moves a long way inland. China and Vietnam can probably engineer their way out of those problems.

Some countries near the equator with political instability are in big trouble.[1] Too poor and too disorganized to upgrade water and agriculture systems.

> An LSE study found that DST transition increases people's feeling of being rushed for time, and the number of hours spent on leisure decreases by roughly 10 minutes following the transition and more specifically the spring transition into DST decreases life satisfaction by around 1.44 per cent.

I think this summarizes it. The negative effects are concentrated around the transition. The positive effects are spread throughout the year. You lose 1.44% life satisfaction for a few days, and gain immeasurably more over the course of the year.

But even this statement is incorrect. FRP frameworks with Observables will remain useful in Java (as they have in other languages that already had coroutines). It's only the use of Observables as _an alternative for coroutines_ that is a transitional technology.

Maybe this is what Brian Goetz meant to say, but this is not what he said.

I'm not in the U. S. but when I tried to cancel my Bitdefender subscription last week (substituted Windows with Linux) - surprise: there isn't a Cancel Option anywhere on my account pages. No chatbot, no e-mail address, no phone number. I opened a ticket with them and the answer I got was: cancel via snail mail with the service provider. I live in a 11th century 200 inhabitants village and the next post office is 10 km away.

These practises have got to stop. We've got to regulate this away, it's borderline fraud.

Baffling? Is just the HN way of calling someone a fucking idiot without violating the rules and pretending to be polite. Just say it to my face.

Is it not obvious human society likes fiction? Is it not obvious that creating fiction requires immense intelligence? That’s my point. If your genius mind can only bend that argument in a singular direction of a “wild take” well I hate to break it to you but you’re baffling.

False information is desirable. Watch tv, read a book. The human race makes billions off of lies not because we are being duped. But because we desire to be lied to. only a genius savant like you needs to be told what the rest of the human race knows.

Look it’s not a “defense” against LLMs as if it’s something that needs defending. It’s like saying I’m defending a ray of light or a gust of wind. Doesn’t make any sense. All im saying is that the LLM is a form of intelligence that has a use versus your brain dead argument that it slipped up when talking to you.

All true except it being expensive though. I'm yet to find a major and reliable cloud service provider who can beat AWS on pricing. In fact, most either use or resell AWS under the hood themselves, even Vercel does as it turned out recently; and they're supposed to be one of the most competitive in the industry.

There are some rare exceptions who have their own large scale infrastructure and don't depend on AWS like Hetzner in EU, Alibaba Cloud in China or Ananta Cloud in India, but this market is still emerging.

Found with AI but this article claims the opposite of the GP.

https://www.americansurveycenter.org/research/the-state-of-a...

And the various articles found seem to agree. The GP claims to have combined 30 surveys. I wonder if they wound-up with one of those statistical paradoxes where a combining of data sets points to something different from each individual data set. But something probably isn't true 'cause the individuals sets are well curated and the combination isn't.

The issue is economies of scale.

On average, only 1 Suffren-class submarine has been laid every 3 years since 2007, and no new orders have been placed since 2020. That is not enough dealflow to support an SoE like TechnicAtome, let alone a private sector nuclear energy player like a Westinghouse. On top of that, the reactor used (the K15) has only been used in just 12 naval applications since 1980.

Entire decades can pass without new military deals for a K15-type reactor, which can lead to skill and experience attrition for what is a fairly complex piece of technology. Meanwhile, the know-how to build a diesel-electric transmission for naval applications is constantly in demand as the same technology is used in commercial naval vessels as well as locomotives.

By trying to justify a dual-use case for SMRs for energy as well as commercial propulsion (which is what both China and India are investing in), it makes it easier to help maintain the knowledge needed to develop nuclear propulsion systems as well as ensure deal flow exists so a Westinghouse-style bankruptcy does not occur.

I was a little taken by the state of American trains if this was true. Two days would mean at least 36h for me and that in turn would mean that the trains would have an average speed of 20mph.

But it turns out that it takes 20h, so twice that speed. Still not fast but better. With that duration it also seems unlikely that the speed is kept artificially low to allow some sleep on the train, as is very common in Europe.

getting the whole world to agree on climate accords didn't work. we blew past the 1 degree allowance we had budgeted for ourselves, so global action together is off the table. What will work, is extraordinary efforts by smaller groups. There's a lot of hard work by tiny groups and individuals to technologies that don't need the whole world to agree to collective action in order to save the planet. The obvious science fiction idea is to put sunglasses between the Earth and the sun, which is a ludicrous idea, because you'd need an insane amount of capability to lift things into space and place them far away from Earth. Once there, you'd just blackmail all the Earth's governments into paying you so the solar panels they rely on will work in order for your venture to be profitable.

You don't need to withdraw from humanity, you only need to withdraw from Big Tech platforms. I'm continually amazed at the difference between the actual human race and the version of the human race that's presented to me online.

The first one is basically great, everywhere I go, when I interact with them they're some mix of pleasant, friendly, hapless, busy, helpful, annoyed, basically just the whole range of things that a person might be, with almost none of them being really awful.

Then I get online and look at Reddit or X or something like that and they're dominated by negativity, anger, bigotry, indignation, victimization, depression, anxiety, really anything awful that's hard to look away from, has been bubbled up to the top and oh yes next to it there are some cat videos.

I don't believe we are seeing some shadow side of all society that people can only show online, the secret darkness of humanity made manifest or something like that. Because I can go read random blogs or hop into some eclectic community like SDF and people in those places are basically pleasant and decent too.

I think it's just a handful of companies who used really toxic algorithms to get fantastically rich and then do a bunch of exclusivity deals and acquire all their competition, and spread ever more filth.

You can just walk away from the "communities" these crime barons have set up. Delete your accounts and don't return to their sites. Everything will immediately start improving in your life and most of the people you deal with outside of them (obviously not all!) turn out to be pretty decent.

The principal survival skill in this strange modern world is meeting new people regularly, being social, enjoying the rich life and multitude of benefits which arise from that, but also disconnecting with extreme rapidity and prejudice if you meet someone who's showing signs of toxic social media brain rot. Fortunately many of those people rarely go outside.

Thank you for this comment, it highlights something that I've felt that needed to be said but is often suppressed because people don't like the ultimate conclusion that occurs if you try to reason about it.

A person considering suicide is often just in a terrible situation that can't be improved. While disease etc. are factors that are outside of humanity's control, other situations like being saddled with debt, unjust accusations that people feel that they cannot be recused of (e.g. Aaron Swartz) are systemic issues that one person cannot fight alone. You would see that people are very willing to say that "help is available" or some such when said person speaks about contemplating suicide, but very few people would be willing to solve someones debt issues or providing legal help, as the case may be that is the factor behind one's suicidal thoughts. At best, all you might get is a pep talk about being hopeful and how better days might come along magically.

In such cases, from the perspective of the individual, it is not entirely unreasonable to want to end it. However, once it comes to that, walking back the reasoning chain leads to the fact that people and society has failed them, and therefore it is just better to apply a label on that person that they were "mental ill" or "arrogant" and could not see a better way.

>now we're making life so stressful people literally want to kill themselves

Is this actually the case? Working conditions and health during industrial revolution times doesn't seem that much better. There is a perception that people now are more stressed/tired/miserable than before, but I am not sure that is the case.

In fact I think it's the opposite, we have enough leisure time to reflect upon the misery and just enough agency to see that this doesn't have to be a fact of life, but not enough agency to meaningfully change it. This would also match how birth rates keep declining as countries become more developed.

Yup, and people get real stupid with it too. I’ve seen people request an update to fix redos vulnerabilities in a go package using the stdlib only. Because some time some where a bot flagged the regex and a CVE was opened with no consideration that it was nonsensical.

You explain that the CVE makes no sense, and you’re met with the response that “ok but did when”

I did, it says Gates has invested in companies and stands to make money. Specifically Breakthrough Energy, a venture capital firm backing clean energy startups, and the Bill & Melinda Gates Foundation, his philanthropy foundation. Is it supposed to something about scientists and how he can afford some really good ones to tell him sciencey things about science so when Bill Gates says something sciencey, we should probably pay more attention to it than random HN comment that presented no credentials?

It's true. Climate change is not an extinction threat. Never was, and certainly isn't now.

Climate change is the COVID of global natural disasters. Is it worth fighting? Yes. Can you do absolutely nothing about it and get away with it? Also yes. Cue the lackluster efforts.

The "really bad" +4C scenarios still have a death toll larger than that of WW2 - but spread out in time and space, across many decades and many countries. And the most vulnerable countries? The countries that are already on the brink. Climate change is not the "great equalizer" people want it to be.

In those "bad" scenarios, the main source of lethality for climate change is: agricultural failures, leading to local shortages and global price spikes, leading to famine. First world countries can eat a sharp +40% spike in food prices, at the cost of quality of life - but there are numerous countries where such a spike would have a death toll attached to it.

> How are the food costs raising if GMO crops are more productive?

The farmer cries we've been hearing in the news over the last few months may be a little overblown, but they certainly aren't coming from a place where food costs are rising...

> Shouldn't this increase supply and lower prices?

Not necessarily. Prices are determined by supply _and demand_.

> So I urge that community, at COP30 and beyond, to make a strategic pivot: prioritize the things that have the greatest impact on human welfare.

Like addressing the exponential growth of income inequality? Unsurprisingly not mentioned at all. Might mean that billionaires have to give up their carbon credit purchases and then how could they be dismissive about their own emissions?

Bill is one of the better ones with his personal capital allocation. He could've just tried to create the fastest sailboat racing team or something. But I find it extremely difficult to take the wealthy seriously when they speak about carbon emissions and climate change. It’s like hearing an arsonist lecture on fire safety.

> Thirty years ago, when I was running Microsoft, I wrote a long memo to employees about a major strategic pivot we had to make: embracing the internet in every product we made.

Is this the one that lead to the term "embrace, extend, extinguish"?

What prevents a farmer from simply switching back to the non-GMO seeds if the GMO option goes up in price? Or even ignoring that, switching to a different cheaper GMO seed from a different company?

I think that's the piece I and others are missing, isn't it ultimately a question of which seeds will make the farmer the most money? If a particular GMO seed suddenly become so expensive that either non-GMO or other GMO seeds are more cost-effective, why can't they just start using them instead?

> This works right up to the point where you try to make the code to support opening transactions

Indeed. It's all well and good to impart some kind of flavour into your code and call it functional, but transactions do not give a crap about style.

A transaction needs to be able to 'back out' to fulfill 'all-or-nothing' semantics. Side effects are what make this impossible.

Contrarian opinion.

OpenAI gets a lot of hate these days, but on this subject it's quite possible that ChatGPT helped a lot of people choose a less drastic path. There could have been unfortunate incidents, but the number of people who were convinced to not take extreme steps would have been of a few orders of magnitude more (guessing).

I use it to help improve mental health, and with good prompting skills it's not bad. YMMV. OpenAI and others deserve credit here.

IMO it’s about minimizing harm at this point.

There’s levels of societal collapse, mass migration can destroy the existing social fabric without necessarily being that terrible. Fertility rates being so low means developed countries will likely want large numbers of immigrants.

At the other end stopping all CO2 production tomorrow would result in severe consequences. We can’t transport food to cities without burning fossil fuels. Obviously that doesn’t mean every current use case is worthwhile, but we can’t ignore the short term here.

The good news is we’re actually making a lot of progress on climate change. The electric grid being ~90% very low carbon emissions by 2050 is a realistic goal and would avoid the worst predictions.

SCSI had a reputation of being very stable and yet very finicky. Stable in the sense that not using the CPU for transfers yielded good performance and reliability. The finicky part was the quality of equipment (connectors, adapters, cables and terminators) something that led to users having to figure out the best order of connecting their devices in a chain that actually worked. “Hard drive into burner an always the scanner last.”

I would be fine with it if all prisoners had similar conditions, which they do not.

Also he and his supports have always criticized prisons for being "too luxurious", so hearing them complaining about his conditions now is infuriating.

As for rehabilitation, there is little hope for him. Prisons also serve to isolate individuals which are dangerous to the society, which he is (he is currently investigated for attempting to rig his current trial, something for which he was already condemned in the past).
Show HN:Interactive RISC-V CPU Visualizer (Sequential and Pipelined)
by mostlyk | 2025-10-28 06:04:49+00:00
I built an interactive RISC-V CPU visualizer for a course that lets you explore how instructions move through both a sequential and a 5-stage pipelined processor.

You can step through execution, watch data hazards resolve, and see how branching and forwarding work in real time.

The goal is to make CPU architecture learning more intuitive for students (and anyone who likes poking around pipelines). The whole verilog code and implementation details are available on the project report!

Right now, the demo supports basic arithmetic, memory, and branch instructions, and includes two pre-programmed examples (a basic ALU demo and a Fibonacci pipeline program).

Would love feedback on how to handle branching better, I remember crushing it due to deadline and it is not handled properly, but haven't looked at the code in-depth after that :p. I also want to do something similar for OS and write from scratch, been seeing a lot of post so any recommendations are appreciated :)

~11% of the US population is on antidepressants. I'm not, but I personally know the biggest detriment to my mental health is just how infrequently I'm in social situations. I see my friends perhaps once every few months. We almost all have kids. I'm perfectly willing and able to set aside more time than that to hang out, but my kids are both very young still and we're aren't drowning in sports/activities yet (hopefully never...). For the rest it's like pulling teeth to get them to do anything, especially anything sent via group message. It's incredibly rare we even play a game online.

Anyways, I doubt I'm alone. I certainly know my wife laments the fact she rarely gets to hang out with her friends too, but she at least has one that she walks with once a week.

Gates is making a speculative case that climate change can be (should be) fought with the needs of the global poor at top-of-mind. He acknowledges the apparent zero-sum nature of it: impoverished people face much greater and more immediate threats than climate change, and fossil fuel tech (for example) really does address those urgent threats effectively. He solves this conundrum by speculating that we can have our cake (help the global poor) and eat it too (slow climate change) by inventing new tools and methods.

I hope he's right. I'm glad he's doing this advocacy. By doing so he's fighting two popular opinions, first that climate change is a hoax, and second, that climate change must be addressed even if it means sacrificing the well-being of the global poor. That said, I have grave concerns that Gates is simply wrong, that we cannot invent our way out of both climate change and the suffering of the global poor. His many remarkable mentions of AI do not, in my opinion, lend strength to his argument, nor does his mention of "almost commercialized" fusion. The former being a gimmick, the latter being forever 30 years away. If our hopes rest on tech like that, then we must prepare to be devastated and pick one side of the zero-sum.
