Sometimes the results of science are unintuitive, but they are facts all the same. The toxicity is an objective feature of the chemical properties of a substance. Whether, to what extent, and how people value such a substance due to its toxicity, and how this plays into their activities which might have assumed its nontoxicity is a subjective matter. The latter is what the manufactuerer is interested in when producing their product; if they consider the former objective fact, it is because the latter subjective evaluation makes the objective fact significant.

"Forty is the old age of youth. Fifty is the youth of old age."

The thing about 40 is, you're not old, but you see your youth dying. If your identity is in being young, sexy, fit, athletic, then that may be brutal. Depends on what your identity is in, and how you handle the loss of it.

Would it even actually help to go down that road though? IMO the expected outcome would simply be that AI training stalls for a bit while "unencumbered" training material is being collected/built up and you achieve basically nothing in the end, except creating a big ongoing logistical/administrative hassle to keep lawyers/bureaucrats fed.

I think the redistribution effect (towards training material providers) from such an scenario would be marginal at best, especially long-term, and event that might be over-optimistic.

I also dislike that stance because it seems obviously inconsistent to me-- if humans are allowed to train on copyrighted material without their output being generally affected, why not machines?

There’s a trivial lower bound of zero, for n = 1.

For n > 1, there isn’t a lower bound. None of the numbers are integers again (https://en.wikipedia.org/wiki/Harmonic_series_(mathematics)#...), and because the difference between successive partial sums goes to zero and the series grows to arbitrary values, you’re bound to find a difference smaller than 1/(2n) somewhere beyond n.

In your example most (not all) libertarians would agree that you need some regulation of those corporations to prevent or minimize external costs, or in some other way factor them in. But the regulations should be as local as possible, and directed only toward the stated objective, with a little other government control as possible. E.g. you can tax my carbon emissions, but you can't regulate my vehicle or fuel consumption.

For example, regarding pollution, prohibiting any discharge of the offending pollutants, or measuring and taxing them in some way - but with no requirements about HOW a corporation should meet these regulations or otherwise run their business.

Unions are fine, and people should obviously be free to join them if they want. But there should not be any laws that require or favor unions, and government employees should not be allowed to unionize.

A government beholden to corporate interests doesn't matter much if the government doesn't have much power. But with power comes interests and influence, always.

It's not easy to be a junior, and we might be speaking with survivor bias, but most juniors don't end up in solid engineering teams, they are merely developers that are much cheaper and from whom you expect much less, but more often than not they are borderline left learning and figuring out things on their own. They need to luck some senior member that will nurture them and not just give them low quality work (which I admit I have done too when I had myself lots of pressure to deliver my own stuff).

Even in less desperate teams, as productivity grows with AI (mine does, even if I don't author code with it it's tremendous help in just navigating repos and connecting the dots, it saves me so much time...) the reviewing pressure increases too, and with that fatigue.

When I was at school (and in the 20th century generally) admitting to anything outside traditional masculinity / heterosexuality made you vulnerable to physical / verbal attack. Which remains the case for a lot of people in the 21st century. If they want to be loud and proud then good for them, but I can understand it if they prefer to keep it quiet. Whereas, at least around me, now, I think you can come out as gay without too much concern for your physical safety.

Conversely, at my school you could be as overtly homophobic as you wanted with no consequences, whereas now you should probably be a lot more cautious if you harbour homophobic sentiments.

Talking about partners in particular, I've had partners I felt fairly safe sharing anything (most things anyway) with, and I've also had partners who would mine our conversations for any kind of viable ammunition. Which led to me being a bit more careful what I said. We can perhaps agree the first kind of relationship is better.

Maybe!

> a squircle doesn’t look like a square with surgery performed on it; it registers as an entity in its own right, like the shape of a smooth pebble in a riverbed, a unified and elemental whole.

But I seem to remember reading about Jobs or maybe Ive stating smooth pebbles as a source of inspiration for how objects should feel in the hand – I believe it was in the context of the first iPhone shape.

Sparse models have same quality of results but have less coefficients to process, in case described in the link above sixteen (16) times as less.

This means that these models need 8 times less data to store, can be 16 and more times faster and use 16+ times less energy.

TPUs are not all that good in the case of sparse matrices. They can be used to train dense versions, but inference efficiency with sparse matrices may be not all that great.

But not all businesses need to use the latest versions of Microsoft Office. They might not even need to use Microsoft Office at all. iPads come with a stock e-mail application, as well as word processing and spreadsheets etc. And if you're using old PCs, you can use old versions of Office. Or WordPad and an e-mail client. They are light-weight.

That's a Topton board from the official Topton store on AliExpress. It's strictly equivalent to buying straight from the manufacturer and will be shipped by Topton not AliExpress.

The Jonsbo case is probably both cheaper and easier to buy from AliExpress than Amazon too to be fair. It's also a Chinese brand.
Show HN: My portfolio is a retro terminal with a virtual file system and more
by daviducolo | 2025-11-27 15:52:00+00:00
Hi HN! I built my portfolio as an interactive bash terminal simulator.

Tech stack: Vanilla JavaScript, no frameworks Features: - Virtual filesystem with directories (about/, projects/, skills/, .secret/) - Working bash commands (cd, ls, cat, sudo, etc.) - Hidden easter egg unlocked via `sudo` command - Three playable games including a graphical Tic-Tac-Toe - CRT scanline effects for that retro feel

The whole thing is ~650 lines of vanilla JS. I wanted to make something memorable that shows both technical skills and personality.

Try finding the secret! Hint: hackers gonna hack

> A more feminine point of view is that we should shield against experiences that lead to a trauma.

I think that's true both for physical and psychological trauma! We should generally avoid preventable injuries and try to live and work with safety in mind.

All I meant is that the phrase "[almost] everyone has experienced trauma" doesn't seem that radical or extreme to me. It seems like common sense. (And it's not the same thing as "everyone is falling apart" or something like that.)

Yeah, that's complicated. I guess from my own experience related to stress and going out of comfort zone what I can speak to is that I have trouble going out of comfort zone when I'm doing something I'm not interested in and when I feel like I have to pretend that I'm someone I'm not. E.g. normal social situations where I have to pretend that I have favourite food, favourite place to go, or I even know places. I zone out on 90%+ topics, and I can't understand why on earth people are talking about these things.

But if I'm passionate about something, I will be excited to present to a large audience, to go through things that you might consider going out of comfort zone, be competitive etc.

Now in school I had so many situations where I had to "be out of comfort zone" in things I wasn't interested in. Social situations I didn't enjoy. I left things to last minute, then stressed, lost confidence, massively. Eventually dropped out of high school.

Luckily managed to get a successful career going where I've been passionately moving forward, and this has massively boosted my confidence too. Now I'm a successful member of society, make quite a bit, pay taxes, etc, and can build the exact life that I want and works out best for me.

i'm a long time lisper, but i don't think this is justified.

implementing prolog/backtracking on top of lisp is certainly possible and not even too hard (see e.g. https://github.com/nikodemus/screamer)

and implementing Coq on top of lisp is also possible.

but IMO the "with ease" phrase is not justified in this context.

if you only mean that lisp will not be in the way if you set out to implement these, then i agree. lisp -- the language and the typical opensource implementation -- will be much less of an obstacle than other languages when chosen as foundations.

"cesspool of intellectual pretension disguised as meritocracy" but there's also a down-side.

Also... I rather dislike most LLM slop, but I like this slop. I tried asking it about a couple different failed companies and it's clear the model annotated prompts with "call any mistake 'hubris.'". I'm sure it would eventually get old, but it sort of reminds me of a drunken CFO explaining to college buddies why sili valley is so messed up.

We're still working a lot of this out because it's actually a relatively new thing culturally - my grandfathers generation would never have talked about mental health at all - but what is pretty clear is that most people do not talk enough about this, and do not deal with mental health very well.

That does not mean we should all be talking to everybody about it all the time. I take stuff into a therapy session I'm not going to discuss anywhere else, because if I started talking about it at work, or even close relationships, I'm asking people without any ability to help me with it to just take it and work it out with me, and that's not helpful.

But at the same time, we do need to talk to people about it. And there are some toxic barriers we could do with addressing.

Men are not "meant" to cry or show vulnerability in almost all contexts in almost all cultures. That's sad, because while we don't all want men breaking down in tears when their coffee order isn't quite right, we also know it's healthy for men to acknowledge and process difficult feelings like grief and rejection.

While most people realise it's not OK to tell a woman she'd look prettier if she smiled more, few people see the hypocrisy in thinking it's OK to tell a man he'd be sexier if he was more confident. That causes problems I think we can all call out and name in modern dating culture.

According to some stats I just pulled up for the UK, surveys suggest that more than 75% of men report as having had mental health issues, but only 60% have ever spoken to another human being about it at all, with 40% of men stating it would have to be so bad that they are considering self-harm or suicide to talk to anyone, ever. This is horrible.

So, sure, perhaps we don't need to talk about Freudian analysis down the pub, and nobody at work wants to hear about you reconciling feelings about how you were treated as a child by members of your family, but please:

Most men need to talk to somebody about their mental health. And for many problems, that somebody needs to be somebody with the appropriate skills and abilities to help them with it.

If you're reading this, and think that might be you, please, for your own sake, go talk to a professional.

You might not gel with the first therapist, counsellor, psychiatrist or psychologist you speak to. That's OK, they won't mind if you say you want to try a few different people. You can find people who will help in your town, on video calls, on apps, all over. Just speak to someone.

Hah, that's great.

My dentist has overhead TVs in all of the rooms. Before a longer appointment I asked if I could bring some over-ear headphones to connect to the TV. Surprisingly nobody had asked that before but they were fine with it. The headphones drowned out the drilling and other noises and helped me zone out into some shows.

> It is also important to note that, until recently, the GenAI industry’s focus has largely been on training workloads. In training workloads, CUDA is very important, but when it comes to inference, even reasoning inference, CUDA is not that important, so the chances of expanding the TPU footprint in inference are much higher than those in training (although TPUs do really well in training as well – Gemini 3 the prime example).

Does anyone have a sense of why CUDA is more important for training than inference?

I have been in therapy on and off through most of my life. There are parts of the process and the profession that are helpful. There are also parts that are paternalistic bordering on abusive. “Literally just someone you pay to the be happiest…” is a small part of the picture. I take issue with this view of therapy, and the idea that it is somehow a universal force for good that will benefit everyone.

I have met some pretty unhinged therapists - both as a client and socially. I won’t even go into the history of psychiatry and clinical care.

One of the questions I like to pose is, what are we doing as a society by sending so many people to therapy? What do these practices do at a large scale? And to all those who decry things like gun violence: if you think our current mental health system would somehow be able to address the larger ills of society if only they had more funding, I have some serious questions about your view of its overarching effectiveness, and the specific effects of these practices.

Well, yes you would be doing that, unless everyone stops eating for example soya.

Soya's actually quite a good example because something like 80% of the mass of soya grown is only suitable for cattle feed, and we need to grow insane amounts of it for human food because it has basically no nutritional value for humans.

What are you going to do with all that? Pile it up and let it rot, emitting huge amounts of carbon dioxide and methane?

Also, Google owns the entire vertical stack, which is what most people need. It can provide an entire spectrum of AI services far cheaper, at scale (and still profitable) via its cloud. Not every company needs to buy the hardware and build models, etc., etc.; what most companies need is an app store of AI offerings they can leverage. Google can offer this with a healthy profit margin, while others will eventually run out of money.

It's worth asking yourself something: people have written substantial responses to your questions in this thread. Here you answered four paragraphs with two fucking lines referencing and repeating what you've already said. How do you expect someone to react? How can you expect anybody to take seriously anything you say, write, or commit when you obviously have so little ability, or willingness, to engage with others in a manner that shows respect and thought?

I really, truly don't understand. This isn't just about manners, mores, or self-reflection. The inability or unwillingness to think about your behavior or its likely reception are stupefying.

You need to stop 'contribiting' to public projects and stop talking to people in forums until you figure this stuff out.

The word trauma is weighty but has a very broad application. I think most people learn about it in the context of e.g. post-traumatic stress disorder (formerly known as battle fatigue, formerly known as shellshock) and associate it with veterans coming back from the war, but it basically applies to anything that have a lasting effect on people. Could be something like parents being emotionally unavailable, childhood bullying, etc.

Wrong, LMDB fully supports multiprocess concurrency as well as DBs multiple orders of magnitude larger than RAM. Wherever you got your info from is dead wrong.

Among embedded key/value stores, only LMDB and BerkeleyDB support multiprocess access. RocksDB, LevelDB, etc. are all single process.

I would say yes. Your weaknesses, if truly shared are weaknesses which can be used against you to hurt you and thereby you are vulnerable to them. Further, even if you don't care about the judgment of others then you can still be harmed by decisions of and social coordination between people who judge you.

We agree, assuming self knowledge, that the judgments of others tell you about them rather than about you.

No, because the terms tends monotonically towards zero. Let an integer m with closest harmonic number H_n be given (i.e. n minimizes |H_n-m|). So m exists either between H_n and H_(n+1) or H_n and H_(n-1). Then |H_n-m| < H_(n+1) - H_(n-1) = 1/n + 1/(n+1). We can make that bound arbitrary small by choosing a large enough n.

First, the US has advanced fab capabilities and in case of a need can develop them further. On the other side, China will suffer a Russia style blockback while caught up in a nasty war with Taiwan.

Totally possible, but the second order effects are much more complex than "leader once for all". The path for victory for China is not war despite the west, but a war when the west would not care.

How much of current GPU and TPU design is based around attn's bandwith hungry design? The article makes it seem like TPUs aren't very flexible so big model architecture changes, like new architectures that don't use attn, may lead to useless chips. That being said, I think it is great that we have some major competing architectures out there. GPUs, TPUs and UMA CPUs are all attacking the ecosystem in different ways which is what we need right now. Diversity in all things is always the right answer.

> And a human artist doesn't need to steal million pictures to learn to draw.

They... do? Not just pictures, but also real life data, which is a lot more data than an average modern ML system has. An average artist has probably seen- stolen millions of pictures from their social media feeds over their lifetime.

Also, claiming to be anti-capitalist while defending one of the most offensive types of private property there is. The whole point of anti-capitalism is being anti private property. And copyright is private property because it gives you power over others. You must be against copyright and be against the concept of "stealing pictures" if you are to be an anti-capitalist.

I think Elementarys Sherlock is closer to the book version. In the BBC version he is totally aloof of social connections and norms, but in the books it is pretty clear, that Sherlock is able to tranverse London society - he had many case with high society people before Watson was part of his life - he just dislikes it.

I would say the X1 Carbon is not a real ThinkPad, and anything with Yoga in the name even less so. His brother's P series should be fine, though. Stick to X (but not X1), T, W, P series, and note that T is the "normal one". Also avoid s variants, e.g. T14s is not the same beast as a T14. Once you've filtered to this point you should rule out a lot of problems with build quality or soldered parts, though even then they don't really make 'em like they used to. Speaking of soldered parts, there was a bit of a dark age where even most of the normal ThinkPads had half or fully soldered RAM, but they're just starting to come back from that. T14 gen 5 is unsoldered, but gens 1 through 3 had soldered RAM, IIRC. Wikipedia has a table you can check for this. So, sadly the used market is gonna be full of the soldered models for a while.

Deepmind gets to work directly with the TPU team to make custom modifications and designs specifically for deepmind projects. They get to make pickaxes that are made exactly for the mine they are working.

Everyone using Nvidia hardware has a lot of overlap in requirements, but they also all have enough architectural differences that they won't be able to match Google.

OpenAI announced they will be designing their own chips, exactly for this reason, but that also becomes another extremely capital intensive investment for them.

This also doesn't get into that Google also already has S-tier dataceters and datacenter construction/management capabilities.

Pure misandrist nonsense. You could have picked Hitler or Stalin to at least have half a point.

Napoleon spread enlightenment values that benefitted generations that came after. Julius Caesar took civilization across a continent. Deng Xiaoping was leader during Tianenmen Square but brought more people out of poverty than anyone else in history.

Being great means being able to do some things others do not like because the resulting upside is better for everyone.

It used to happen, I'd say less than 5% of the total vuln reproducers are probably 'shared' at this point.

At last count I'd written close to 2000 reproducers and approx 400 of those were local privesc for product security.

Security teams are usually highly discouraged from sharing exploits/reproducers as they have leaked in the past. My spectre/meltdown ended up on the web and someone else took credit, sad.

Sometime in my late 30's or early 40's I noticed that groups started deferring to me as the arbiter of disputes and decision maker. They also stopped being as playful with me.

I hadn't changed my personality significantly, and I was baffled for a long time. Then I realized that I had become a 40 something man with a touch of grey and some gravel in his voice.

Somewhere along the way people had just automatically started thinking of me as the Boss archetype instead of the Bro archetype.

It was startling to me that my dumbass opinion was suddenly being held in higher regard due to the simple expedient of becoming old.
