I’d call it stupidity rather than masochism.

It wasn’t that hard to see that energy needs were only going to increase rather than diminish. And not because of ai datacenters, but (to make a simple example) for example because of the already ongoing at the time push for the electrification of the automotive industry.

It’s also crazy that the initiative was supposed at all by environmentalists.

Anyway, props to Mertz for admitting the mistake, we’ll see if they will fix it somehow.

>We ban gambling for children, even though the vast majority of harm caused by gambling comes from adults. Now you could argue that more harm would befall children if we let them gamble, but I honestly don’t think you should.

Yeah only children stealing credit cards to satisfy their addiction.

I don't know if the poster ever saw a child but they are largely sociopathic for a long time and will go great lengths to get their will.

I feel like if the conclusion is "ban it for everyone too" I'm okay with it?

But the argument seems to get a little lost along the way.

Yes, adults are susceptible to the same vices as children. However (as the author writes) children have poorer impulse control. They are also less inclined to or unable to consider the repercussions of their actions.

You wouldn't try to get a toddler to stop smoking by telling them it'll put them at a high risk for cancer at old age.

Speaking of smoking, anti-smoking campaigns in the US in the 90s led to a vast reduction in teen use and adult use alike.

So there is notable lasting benefit in protecting children while they lack the foresight.
Show HN: Tidey – A tiny Mac menubar app to triage Desktop and Downloads clutter
by lagorita | 2026-01-15 13:14:17+00:00
Hey HN! I built Tidey because my Desktop was always a mess.

The problem: Files pile up on Desktop and Downloads. Screenshots, PDFs, random downloads. You save them "temporarily" and forget about them for months.

The solution: Tidey sits in your menubar and watches those folders. When you're ready to clean up, it shows you each file one by one. You preview it, then click Delete (goes to Trash) or Keep (moves to ~/Documents/Kept/, organized by year/month).

That's it. No complex rules, no automation magic. Just a fast way to make decisions about files you've been ignoring.

Tech stack:
- Swift/SwiftUI (native macOS)
- Sparkle for auto-updates
- Landing page: Next.js on Cloudflare

I'm a solo dev, happy to answer any questions about the app or the build process.

There are quite a few things wrong with this article, but above all, placing children on the same level as adults overlooks how crucial our early years are.

Overall, this blog post feels somewhat outdated.

I also can't clearly grasp the author's position: are they arguing that we should ban this for everyone, or not ban it at all? Or is the point simply that the people who write such bans or laws do so because the law doesn't apply to them?

I think this is a good point. What differentiates alcohol and social media? Well, social media is not physically addictive, but it's pretty clearly psychologically addictive. Along those lines it would be hard to argue that children should have unfettered access to social media. Social media is also _not_ like TV in that there's psychologists and algorithmic engineers working hard to make these types of apps as addictive as possible. Not to mention the fact that children obviously can't consent to having their data harvested, most ADULTS don't understand the ramifications of that, much less children.

All of this also applies to adults, I don't like how corporate profit-seeeking algorithms dictate public discourse and I think it's perfectly reasonable to combat this. The great question is how to do so without trampling on people's right to freedom. The EU tends to combat "misinformation", but this has loads of problems, and I think it misses the mark of what the problem truly is. In my opinions it's the algorithms that maximize fear responses and lead people down rabbit holes that's the true problem.

I think the best way to combat it is by supporting federation and decentralization of the internet and attacking the advertising industry that maximizes eyeballs and time spent on the platform, rather than providing service to paying users. It also has the beneficial side-effect of increasing freedom of thought and speech rather than limiting it.

I know some people see the fragmentation of communities as the leading cause of echo-chambers, but this is not my impression. Actually, the smaller internet communities are often less extreme than algorithmically dominated central-hubs. Pseudonymous small communities function more like the local village that tends to mitigate extremism as the loudest, more extremist, community members can be challenged, without those challengers drowning in potential oppressive moderation and hive-mind mentality.

Kiln wraps up all the parts in on app. Just drag and drop in files. You can easily compare different configs on your dataset: extraction methods, embedding model, search method (BM25, hybrid, vector), etc.

It uses LanceDB and has dozens of different extraction/embedding models to choose from. It even has evals for checking retrieval accuracy, including automatically generating the eval dataset.

You can use its UI, or call the RAG via MCP.

My Desktop has been a disaster for years. Screenshots pile up, downloads I forget about, files I save "just for now" and never touch again.

I finally got tired of it and built this. It's a simple menubar app - shows me each old file, I preview it, then hit Delete or Keep. That's the whole thing.

Kept files get organized by date automatically. Deleted stuff goes to Trash so I can recover if needed.

First time shipping a paid Mac app. Would love to hear what you think or answer any questions about the build.

Why shouldn't AI be able to sufficiently model all of this in the not far future? Why shouldn't have it have sufficient access to new data and sensors to be able to collect information on its own, or at least the system that feeds it?

Not from a moral perspective of course, but the technical possibility. And the overton window has shifted already so far, the moral aspect might align soon, too.

IMO there is an entirely different problem, that's not going to go away just about ever, but could be solved right now easily. And whatever AI company does so first instantly wipes out all competition:

Accept full responsibility and liability for any damages caused by their model making wrong decisions and either not meeting a minimum quality standard or the agreed upon quality.

You know, just like the human it'd replace.

> They know the code best.

Two major issues occur unless they have experience.

1. The developer will often have what is called "Acquired knowledge". That is information that is relevant but isn't in any of the files and the developer assumes other developers know what they know.

2. Often is the case that there is more information required that doesn't sit inside the code and is not evident to get the program to work. Quickest way to find that is to get a newbie on a clean machine to follow only the instructions.

The US has done well historically, roughly on par with China on per capita renewable rollout, slightly ahead of China between 2019-2023 but probably falling behind now.

China being so big and populous makes it hard to make simple comparisons.

edit: looked it up, US is still ahead of China as of 2024:

Luckily so many were made, they will be around for a while yet. For years now you've been able to buy (recycled?) ones on Ebay or Aliexpress, and at a price much cheaper than the new ones sold for.

It will probably be a decade or longer until those sources start to dry up, but even at that the Z80 will never become as rare as say, a SID chip.
Show HN: AI-SkillForge – Generate Anthropic Agent Skills from Natural Language
by lhassa | 2026-01-15 13:16:38+00:00
I built a CLI tool that generates Anthropic Agent Skills using AI. Describe what you want in plain English, and it creates a complete SKILL.md file with structured instructions, examples, and edge case handling.

Example:

pip install ai-skillforge[ai]
export ANTHROPIC_API_KEY=your-key
skillforge generate "Review Python code for security vulnerabilities"

This creates a ready-to-upload skill with:
- YAML frontmatter (name, description)
- Step-by-step instructions for Claude
- Multiple realistic examples
- Edge case guidance

You can also improve existing skills with AI, validate against Anthropic's requirements, and bundle into zip files for upload.

Works with Anthropic, OpenAI, or Ollama as the generation backend.

GitHub: https://github.com/lhassa8/skillforge
PyPI: https://pypi.org/project/ai-skillforge/

Built this because writing good skills from scratch is tedious, and I wanted something that could scaffold production-quality instructions quickly. Feedback welcome!

Banning social media will never work, just as banning prostitution, drugs cigarettes and gambling don't work (in a broad scale). What we can do is change the public (and our) perception of it. Understanding you have a problem is always the first step in any N-step program for whatever addictive substance. Most adults don't see their own consumption and behaviour around social media as harmful or problematic or simply deny they have a problem - just as is the case with any other substance. That is where we have to start. Once we (as in we as society) start agreeing that social media on average (!) is harmful, the narrative shifts. Right now parents don't think they do anything wrong by giving a 10year old a smartphone unsupervised. Everybody in society would look condascending on the parents if they hand out cigarettes to a 10yo child - probably even calling the cops. THAT is the sentiment in society where we need to be. It starts with us adults condemning social media use first, else all attempts to outlaw or ban it will fail.

>Frankly, social media is just too ingrained into the social fabric, and is just too useful and addictive to be banned. So if you have to do something and you can’t meaningfully do anything else…I guess it’s a ban for children.

this is something I've been dwelling on for the past couple days. I've avoided social media my entire adult life, and I'm realizing its akin to not having a car in a suburban sprawl, I can't interact properly with a lot of the modern internet, because of it.

Of course there are advantages, which I don't think i need to state in this community...

But i feel this is something people overlook when discussing banning social media for children. There is a balance to be struck, like anything.

>In both of these cases (and in others), the harms are there for children and adults, but it’s only children who get banned.

>I don’t use TikTok and it’s no skin off of my back if it gets banned. Banned or not, though, I don’t see a reason to ban it only for children. It doesn’t seem to be more harmful for them. They don’t seem to be using it lots more than adults.

>If you’re going to ban TikTok because it’s harmful or for geopolitical reasons, fine. But ban it universally; if we’re not willing to do that, stop pretending that a child-only ban is principled. A child-only ban is what you do when you want to do something but can’t think of anything better to do, and you don’t want to impact voters.

There are now enough statistics to prove that social media has a negative impact on the mental health of users, especially children and adolescents. Even Meta has kept a study on this topic under wraps. What OP is doing here is putting adults and children on the same level and saying that what applies to children must also apply to adults. The difference, however, is that we as adults have a responsibility toward children. Children enjoy special protection in society and, for good reason, are subject to limited criminal liability. We do this because we assume that children belong to a vulnerable and easily influenced group, and lack the mental and moral maturity to adequately assess their actions. We assume that adults have the necessary mental and moral maturity to adequately assess the consequences of their own actions, which is why they are granted more rights but also more responsibilities than children. OP does not reveal any contradiction or other ‘gotcha’ moment here, unless he generally takes issue with the relationship of responsibility between adults and adolescents.

Comrade, far left scum like you commits terror attacks on the regular, be it the arson attack that caused a blackout in Berlin for days or a bomb attack against refineries, bashes dissenters' heads in with baseball bats and block highways and throw rocks at police when the opposition dares to hold a congress.

But the Gleichschaltung of the state media really pays for itself, who would otherwise fall for thid Alex Jones-level of disinformation.

One thing that comes to mind is latency in a HPC context.

If you can fit your entire software stack into L3 cache, you never have to access memory and benefit from insanely good latency.

This was a thing in HFT like ~5-7 years ago, where you might have bought a 28 core Xeon, disable all but one or two cores and benefit from ~30mb L3 cache, which can fit an entire Linux Kernel, an SSH server and your trading software.

> I wonder if a combination of all of those may work for a subset of songs, but I don't think you can do it with any confidence :(

Thats a solid point. Pretty much all of my ideas are probabilistic. I suspect you're right and it will have to work a bit like spam detection, where each "fail" for a test is seen as one indicator that adds to a score. Then above a threshold score it's flagged for further review and sent to a "spam" folder where a human can judge.

Oh, I agree with you in this regard, but your take was... overtly simplistic in a crucial, key detail.

Concerning litter presence in general - as much as the poor manners the distinct absence of the bins strongly amplifies the problem. At least in my country (pretty large western country) - most of the public spaces (streets, etc) lack ANY sort of the bin, and while it's easy to tuck the plastic wrapper from the food and take it home, I'd say people are much less inclined to carry a stinky cigarette but or leaking can for a couple of miles.

Batteries are not actually becoming dirt cheap. And if you do the math of how much you need, even if batteries get cheaper by 50% (and that is unlikely just based on materials cost) its nowhere near enough.

> decentral production wins amidst clusterfucking climate catastrophes

If you do the math you will see Germany could have actually saved money if they had build nuclear in the 2000s.

> solar and wind already are cheaper than anything else

Only if you look at levelized dispatch cost, not if you actually look at is as a system for sustainable reliable power for a whole industrial country.

Why AI divides programmers --- because the productivity benefits of AI are debatable.

It often takes longer to review, understand, decipher and debug generated code than it does to write your own.

Those enamored with AI seem to sidestep this review process until forced to engage with it at some later date.

This is personal opinion that has recently started to garner support from formal studies.

"When developers are allowed to use AI tools, they take 19% longer to complete issues — a significant slowdown that goes against developer beliefs and expert forecasts."

True, but misleading. There are practical blocks to children drinking alcohol: they can't buy it from shops or bars. In the UK, you can buy it from 18, and you can consume it in a pub/restaurant from 16 but only with a meal and supervised by an adult. In France, you can buy it in bars from 16.

An analogy would be that social media consumed by children is surely less harmful when it's a parent holding their own phone towards a child to show them a few selected photos from their Instagram feed. I doubt most people would object to that, even those that want to ban social media from children.

> We are seeing a transition from the user as a customer to the user as a resource.

I'd argue that this started 30 years ago when automated phone trees started replacing the first line of workers and making users figure out how to navigate where they needed to in order to get the service they needed.

I can't remember if chat bots or "knowledge bases" came first, but that was the next step in the "figure it out yourself" attitude corporations adopted (under the guise of empowering users to "self help").

Then we started letting corporations use the "we're just too big to actually have humans deal with things" excuse (eg online moderation, or paid services with basically no support).

And all these companies look at each other to see who can lower the bar next and jump on the bandwagon.

It's one of my "favorite" rants, I guess.

The way I see this next era going is that it's basically going to become exclusively the users' responsibility to figure out how to talk to the bots to solve any issue they have.

> And since renewable + batteries is now cheaper than nuclear, we should spend our money and time wisely.

Eggs in one basket. Renewables are good, but it gets cloudy, it becomes night, it might not be windy. Nuclear will output power come rain or shine, and like I said, it's not like China isn't investing in advanced fission. They're throwing money at everything to see what sticks. They're working on SMRs, molten salt, thorium, and more.
Show HN: See the best daily US stock trades with entry and exit timing

Hi HN,

I built Finsuba Premium to solve a problem I kept running into while trading:

Most sites highlight “top gaining stocks” over a fixed time window (e.g. 9:30–4:00), but that often hides the actual tradeability. A stock can finish the day up big while offering very different outcomes depending on when you entered and exited.

Finsuba Premium sends a daily and weekly email showing the top-performing U.S. stock trades, based on identifiable entry and exit points rather than broad time-based gains. It includes:

- exact entry time & price
- exact exit time & price
- trade duration and performance

It’s not a signal service or alert system. Everything is processed at the end of the trading day and ran through minute by minute. I built this for traders who want to improve by reviewing winning setups consistently, rather than reacting to alerts in real time.

Link: https://www.finsuba.com/premium/

Happy to answer questions about how the trades are selected, the data pipeline, or the product itself. Feedback very welcome.

Eh, I feel like if we know there is a vulnerable population (children), and we know that the social media will cause harm (increased suicides, depression, etc), and we know that that ultimately it puts people in a place where they can't reasonably choose a better path (collective action, power imbalance, poor reasoning, no long-term perspective, social peer pressure, etc.), and where the parents are unable to reasonably control the behavior too, then a ban is warranted.

By that token, I honestly think we should ban more things that we know don't have an upside, and only have downsides, and the people who partake are generally doing so because of mental / physical shortcomings. In other words, if we know a reasonable person would not want to partake in a behavior unless due to manipulation and weakness, then I feel protecting that person is a kindness.

I myself have suffered from addictions that I can't seem to easily "choose to stop" even though I constantly wish I could. I really wish I wouldn't have been exposed to these things when I was younger and thought it was just fun. If I could, I would pay to go back and prevent my younger self from ever trying it -- because I had no way to know. And then I am a bit astonished none of the adults had that kind of concern. Sure a few people said "that stuff isn't good", but ultimately that lost to all the other factors (constant propaganda, ads, peer pressure, convenience, taste, addictive qualities, cost). It was never a "free choice" because there was huge information and power imbalance at play, and the "responsible adults" who could help did nothing.

That's not sufficient, at least from the likes of OpenAI, because, realistically, that's a liability that would go away in bankruptcy. Companies aren't going to want to depend on it. People _might_ take, say, _Microsoft_ up on that, but Microsoft wouldn't offer it.

I assume "harness" here just means the glue that feeds one model's output into that of another?

Definitely sounds expensive. Would it even be effective though? The more-privileged rings have to guard against [output from unprivileged rings] rather than [input to unprivileged rings]. Since the former is a function of the latter (in deeply unpredictable ways), it's hard for me to see how this fundamentally plugs the whole.

I'm very open to correction though, because this is not my area.
