holy heck there is so much wrong about this video. i can't believe "internet influencers" can just turn on their cameras and spew so much untruth without a care in the world...

comparatively wikipedia is imperfect, but much better than this kind of slop.


Feel free to actually articulate the actual issues you’re referring to.

It’s been a while since I watched it but the thing I remember taking away was you can do a lot better than Wikipedia, and he encouraged people to spend more time looking at primary sources for deeper research, and points out how it’s the basis of a lot of slop on YouTube.


Seems like he's recommending secondary sources over Wikipedia as a tertiary source.

That’s probably more correct actually, I guess primary source would be talking to witnesses or the subjects themselves.

Although, due to Wikipedia's own policy, that it must cite other reliable sources, it can never be a source of first-hand news.

Wikipedia's main form of academic critique is to "verify" content through a Google search.

> the smartphone replacement cycle is the only predictable cash flow

people are holding onto their phones for longer: https://www.cnbc.com/2025/11/23/how-device-hoarding-by-ameri...


Still more predictable than GPU buys in the current climate. Power connector melting aside, GPUs in most cases get replaced less frequently than cell phones, unless of course you have lots of capital/profit infusion to for whatever reason stay ahead of the game.

Heck if Apple wanted to be super cheeky, they could probably still pivot on the reserved capacity to do something useful (e.x. revised older design for whatever node they reserved where they can get more chips/wafer for cheaper models.)

NVDA on the other hand is burning a lot of good-will in their consumer space, and if a competitor somehow is able to outdo them it could be catastrophic.


Yea, it’s anecdata, but I only replaced my 1080 ti about 1.5 years ago.

Graphical fidelity is at the point that unless some new technology comes out to take advantage of GPUs, I don’t see myself ever upgrading the part. Only replacing it whenever it dies.

And that 1080 ti isn’t dead either, I passed the rig onto someone who wanted to get into PC gaming and it’s still going strong. I mostly upgraded because I needed more ram and my motherboards empty slots were full of drywall dust.

The phone I’m more liable to upgrade solely due to battery life degradation.


I replaced my 1080 Ti recently too (early 2025). I had kept it as my daily GPU since 2017. It was still viable and not in urgent need of a replacement, even though my 1080 Ti is an AIO liquid cooled model from EVGA, so I'm surprised it hasn't leaked yet. It's been put through a lot of stress from overclocking too, and now it lives on inside a homelab server.

The 5090 I replaced it with has not been entirely worth it. Expensive GPUs for gaming have had more diminishing returns on improving the gaming experience than ever before, at least in my lifetime.


Millions of lines of code in a decade?! One million would be 400 loc every working day. And he said millions. And that's only counting code he open sourced.

I don't believe it is possible to "carefully" write thousands of lines of code every single day.


> introduce a third party like Tailscale.

Well just use headscale and you'll have control over everything.


That just moves the problem, since headscale will require a server you manage with an open port.

Sure, tailscale is nice, but from an open-port-on-the-net perspective it's probably a bit below just opening wireguard.


serialization/deserialization will always be needed unless you got all your programs working with the same ABI. it's just that in nushell's case you aren't serialize to human readable text.

Not a "normal" option though. They plan to hide it away inside `gsettings` so only power user who already knows about middle-click paste will be able to find it and enable it. This completely destroys discoverability.

And a couple years later it is removed as only a minority used it.

That's not the new Atlas they are announcing.

It's interesting so far we have not seen the new Atlas actually functioning. In the past Boston Dynamics announcements have always been done with real hardware. But this time it's only with models and CGI.

What happened?


Yeah they say "we couldn't pry the model out of our engineer's hands" which is obviously nonsense. What they mean is that it doesn't work yet.

This smells a lot like a hacker thought because they are exceptional in one field (cybersecurity), they therefore are exceptional in all fields. The result is that information presented in this article is very surface-level, and quite biased.

As a much better alternative, I would recommend "debt" by david graeber, which is amazing.

Is your comment perhaps in reference to the comment ‘ the assumptions and estimates that go into it, I recommend Financial Intelligence by Joe Knight and Karen Berman’ and not the parent comment you’ve replied to?

lol, good guess. I must have clicked wrong - I thought I was replying to the comment "this is bad, don't read it"

Graeber is controversial. Archeologists hate how he argues by ad hominem and does not appear to understand the works he cites, to make his argument.

I can't speak to his work on finance as a whole. Regarding deep time, his claims about pre-literate society from archeology are not widely supported, they use thin evidence to argue badly.

His anarcho-socialism isn't the concern. It's his lack of historicity, and inability to bring his peers with him on radical ideas which concerns me.

He's dead, he can't defend himself. So there's that.


Just in case anyone is put off by this comment, I want to second the recommendation of Debt: The First 5000 Years. It's excellent, and it has as a free, chapter-by-chapter audiobook on YouTube.

As for Graeber being controversial: yes, though I vaguely recall "The Dawn of Everything" being (moreso) the trove of interesting historical anthropological hypotheses, rather than "Debt"?

Anyway, it's been a while, but my main point is that I wouldn't let Graeber's controversial-ness stop anyone from reading Debt. If anything, going in with that information makes you think harder about the topics he covers.


I totally agree. He writes well. I think the dawn of everything is a good read, and I will read debt, but without wanting to give in totally to 'appeal to authority' I think you have to recognise Graeber didn't win friends.

I think you'll enjoy it. My impression is he'd have won more friends with Debt than he did with the Dawn of Everything. Perhaps not literally, but I do remember thinking Debt made stronger cases on average, and was more philosophical than creatively-antagonistic in its weaker evidence parts.

Fun fact, David Graeber had an HN account: https://news.ycombinator.com/user?id=davidgraeber

I was interested to read that. Thanks. I think aspects of his personality came out in that, but also the horrible truth that "public intellectuals" become targets for many people. I have no doubt if some of the names I have catcalled on HN like Malcom Gladwell or Ray Kurzeweil were online in HN they'd be coming in for some flack, from people like me (with lesser chops, but a lot of opinion about them, as public intellectuals)

I saw this in the flesh at a book festival. Dale Spender, a notable feminist author who moved sideways into IT tech (she was involved with online learning systems) did a book talk and the majority of questions from the audience were "Gotcha" attempts about here philosophy and feminism, with nothing to do with the subject at hand.


As a fan of Graeber, I’m interesting in reading counter arguments to his writing. Could you point out where I can read up more about what archaeologists think of his writing?


the only thing it takes to be exceptional in most fields is time and effort. there is no secret sauce. There is not something innate that "finance people" have that "computer people" don't, other than a willingness to trudge through boring finance-related crap and vice-versa.

This is all spawned from insecurity that your prestigious degree or whatever can be replicated through independent learning


biased hackers are the best kind of hackers :)

Being exceptional in cybersecurity is a pretty good indicator that someone will be successful in other fields. A good cybersecurity person will understand that cybersecurity is a mix of technical mastery and the art of understanding human behaviour.

> Being exceptional in cybersecurity is a pretty good indicator that someone will be successful in other fields.

I am not so certain about this. In particular being exceptional in cybersecurity does not make you good at playing political games or having the traits that a lot of bosses want from employees (I will attempt to avoid starting a discussion whether I consider such traits to be good or bad).


Exceptional includes soft skills too.

1. You re-defined the scope of what it means to be exceptional in cybersecurity.

2. One example of a trait that many bosses desire, but is not a social skill per se is docility.


If a doctor excels at health science but is so terrible at client communication that their patients do not understand or follow medical advice and instructions, are they a good doctor?

I would say: medicine consists of many sub-disciplines and there are many very different positions for doctors in the medical system, including ones where you have a lot less to discuss with patients.

So, yes, such as doctor who excels at health science is very likely a really good doctor, but this does not imply that this doctor will excel in every position in the medical system for which doctors are hired.

This is very consistent with my claim that I don't think that "being exceptional in cybersecurity is a pretty good indicator that someone will be successful in other fields".


Let me guess - you work in cybersecurity?

This is XKCD #793 all over
