Yes and no? I think irl conversations were always more about connecting "what's going on in your life, who did what, I'm worried about X" eg with family. On the rare occasion there's a disagreement over facts, it's absolutely great to have a LLM ref to adjudicate. So the LLM is supplementary. It even does emotional persuasion better than I do. But yes I do find overall I have slightly less subjective need for irl conversations because I have been talking with the LLM.

For me I have been to Israel end of covid before I heard apartheid accusations. I talked to Arabs there and honestly if I was offered to swap my Russian rights with rights of Arab in Israel I would go for it. I mean healthcare alone... When I looked up the allegations it appears that most alleged "apartheid" laws were common to other countries, so why double standard.

It sort of made sense if I thought just of West Bank. One reason, freedom of movement. I did not see from the inside but from what I read it is semi closed like a warzone with checkpoints and all. What's worse is that it is supposed to be closed for everybody but allegedly it is not equal and Israel military tolerates Jews but can be way overly strict to Muslims. Some people mad at Netanyahu for it.

But it's a weird limbo, people say it's apartheid and then the same people also say it's occupied and not really part of Israel. (Except for people who also say Israel shouldn't exist but I wouldn't listen to them, because then why a shitton of militant Muslim countries are allowed to exist right there but Israel isn't considering it is much more democratic and Jews were there as early if not earlier than Muslims)

On the spectrum of grey areas from “request” to “demand”, we not only have to evaluate the literal words typed but also the context and expectations of open source. As the libxml2 maintainer indicates, they are no longer willing to participate in security bug secrecy and priority. In hindsight, those expectations that most take for granted as necessary must have demanded considerable time and energy from them. They could have said no at any time, but not as easily as turning down a feature request. For asocial-leaning maintainers (hi!) saying no to security processes is no more difficult than refusing any other request — but for the vast majority of maintainers, it will take an effort of courage and will to refuse the ‘demands’ — the social pressures, the contexts and expectations — of security’s best practices, reporting processes, and priority overrides. (Elsethread, the individual making demands in an issue is also a case of ‘demand’ rather than ‘request’, that isn’t much in the in-between grey area at all.)

Psychologically, it hits different when a leecher — someone whose uploads are not greater than some minimum threshold — begins demanding something; what they receive then is not just a free copy of the maintainer’s work to profit from, but also the specialized work of the maintainer to satisfy or reject their request. The cumulative impact of dealing with parasites is distinct from the demotivating effect of profitable leechers who silently download their work and never say anything at all?(and also from the motivating effect of seeing millions of people benefiting from leeching — adoption is often a significant reward). Torrenting has no language for this difference, as in torrenting there is no such problem; so I did some research and chose ‘parasite’ here. I recognize that, scientifically, the animal ‘leech’ tends to be viewed as ‘parasitic’; but there’s a clear difference in connotations, as a torrent leecher is not viewed with – does not view themselves with — the same disgust and loathing as parasites are.

A pull up bar is the first thing you should get since it can target muscles that are hard to do any other way. For most other muscles you can find some other way to strengthen them just using body weight exercises.

For most people a pull up bar plus body weight exercises will get them everything they want: enough fitness for good health. If you want to win competitions you need the right equipment (different competitions need different equipment).

WordPress backend is PHP, so it makes sense to use the same language throughout. I've been doing PHP professionally for a long time, and as long as you know other languages (which you do), you surely won't get pigeonholed into PHP roles forever.

IMO the question is not whether you should take a PHP job, it's whether you should take a job building a hosting control panel. Is that type of work something you're interested in? Do you want to become an expert in web hosting? There are lots of companies in the web hosting space, so it could be a solid career domain, but not if it's super boring to you.

"I'm a Rationalist"

"Here are some labels I identify as"

So they arent rational enough to understand first principles don't objectively exist.

They were corrupted by words of old men, and have built a foundation of understanding on them. This isnt rationality, but rather Reason based.

I consider Instrumentalism and Bayesian epistemology to be the best we can get towards knowledge.

I'm going to be a bit blunt and not humble at all, this person is a philosophical inferior to myself. Their confidence is hubris. They haven't discovered epistemology. There isnt enough skepticism in their claims. They use black and white labels and black and white claims. I remember when I was confident like the author, but a few empirical pieces of evidence made me realize I was wrong.

"it is a habit of mankind to entrust to careless hope what they long for, and to use sovereign reason to thrust aside what they do not fancy."

I'd just wire some in quads, and some in pairs to save on complexity.

Then maintain a 1/10 lux range with the combinations. Note I'm not doing the math, just showing how simple it is to work around. It's all just napkin.

The cost isn't a biggie, if it's for a target market and shares the rest of the assembly.

That is how I normally hear the marketing theory described when people go into it in more detail.

I'm glad you ran with my burger chain metaphor, because it illustrates why I think it doesn't work for an AI company to intentionally try and advertise themselves with this kind of strategy, let alone ~all the big players in an industry. Any ordinary member of the burger-eating public would be turned off by such an advertisement. Many would quickly notice the unsaid thing; those not sharp enough to would probably just see the descriptions of torture and be less likely on the margin to go eat there instead of just, like, safe happy McDonald's. Analogously we have to ask ourselves why there seems to be no Andreessen-esque major AI lab that just says loud and proud, "Ignore those lunatics. Everything's going to be fine. Buy from us." That seems like it would be an excellent counterpositioning strategy in the 2025 ecosystem.

Moreover, if the marketing theory is to be believed, these kinds of psuedo-ads are not targeted at the lowest common denominator of society. Their target is people with sway over actual regulation. Such an audience is going to be much more discerning, for the same reason a machinist vets his CNC machine advertisements much more aggressively than, say, the TVs on display at Best Buy. The more skin you have in the game, the more sense it makes to stop and analyze.

Some would argue the AI companies know all this, and are gambling on the chance that they are able to get regulation through and get enshrined as some state-mandated AI monopoly. A well-owner does well in a desert, after all. I grant this is a possibility. I do not think the likelihood of success here is very high. It was higher back when OpenAI was the only game in town, and I had more sympathy for this theory back in 2020-2021, but each serious new entrant cuts this chance down multiplicatively across the board, and by now I don't think anyone could seriously pitch that to their investors as their exit strategy and expect a round of applause for their brilliance.

It's a compromise between having a geometry that is rigid enough to ensure the bottom and top planes stay aligned while the telescope slews up and down, while having a practical shape at the bottom (a square) and avoiding struts going into the light path, which happens if you do an hexapod shape without making the base larger to compensate. Since his initial goal was to make this printable on an ender3 build plate, the smaller square shape was preferable.

> Well, how much have the shipments solved? Any peace agreement after these years of carnage will be a lot worse for Ukraine than was on the table in 2022.

What peace deal was on the table for Ukraine in 2022? Surrender and let their population be brutalised by the Russians, their culture and language erased, their civilians and military tortured and raped? Great deal, I wonder why they didn't take it.

It has solved the immediate problem of limiting the Russian expanse and subsequently war crimes in Ukraine. It's literally the best that can be done right now, until Putin realises he can't win.

> Labeling those with different views on Ukraine-Russia policy as putinists is the same phenomenon as Israel critics being antisemites or pro-Palestine.

No, because both sides in the Israel/Palestine conflict both have good points and deficiencies. Both have a right to exist, and both have done terrible things to one another. There are nuances, and there can be a solution where both exist. But both need to take part of it.

In Ukraine, Russia is a genocidal regime invading its neighbour. Ukraine being forced to give up territory and concessions on army/NATO restrictions would just guarantee they'll be weaker for Russia to invade again in a few years. If you want peace, take it up with Putin. Preventing help getting to Ukraine to defend itself is serving Putin's interests and nothing more. The war stops the second Putin stops.

There is a lot of discussion in this thread about the novelty of this research. This is because TAMU's PR piece is not accurately describing what this research is about. The paper's abstract highlights a different contribution altogether. They show the evidence that fingerprinting is used for advertising (which might be violating GDPR in some cases)

While advertising has become commonplace in today's online interactions, there is a notable dearth of research investigating the extent to which browser fingerprinting is harnessed for user tracking and targeted advertising. Prior studies only measured whether fingerprinting-related scripts are being run on the websites but that in itself does not necessarily mean that fingerprinting is being used for the privacy-invasive purpose of online tracking because fingerprinting might be deployed for the defensive purposes of bot/fraud detection and user authentication. It is imperative to address the mounting concerns regarding the utilization of browser fingerprinting in the realm of online advertising.

This paper introduces "FPTrace" (fingerprinting-based tracking assessment and comprehensive evaluation framework), a framework to assess fingerprinting-based user tracking by analyzing ad changes from browser fingerprinting adjustments. Using FPTrace, we emulate user interactions, capture ad bid data, and monitor HTTP traffic. Our large-scale study reveals strong evidence of browser fingerprinting for ad tracking and targeting, shown by bid value disparities and reduced HTTP records after fingerprinting changes. We also show fingerprinting can bypass GDPR/CCPA opt-outs, enabling privacy-invasive tracking.

In conclusion, our research unveils the widespread employment of browser fingerprinting in online advertising, prompting critical considerations regarding user privacy and data security within the digital advertising landscape.

There are several other use cases that Starship is well optimized for. Not surprisingly it's also fairly optimal for building large LEO constellations, It's a little bit large for the current Starlink satellite size, but if the Starlink satellites get significantly larger and more capable, Starship will be fairly optimal.

Given SpaceX's business, it seems safe to assume that Starlink was a design goal with at least a similar priority to the Mars goal.

Another use case it'd work fabulous for would be a LEO space hotel business.

Finally, it's also a great rocket for any use case that involves returning large masses, even if the return is from higher than LEO. Yes, it'll be a thirsty beast requiring many refuelling trips, but the tyranny of the rocket equation makes it hard to do any better. If you want to return dozens of tons from the moon or elsewhere you'd be hard pressed to do better than Starship.

> that's why resin printing is not everyday parts but figurines.

It's probably more to do with it being messy, smelly, and overly finicky business[0] compared with FDM (but there's zero chance of burning your house down, I suppose.)

[0] levelling the build plate, cleaning the FEP on failures, replacing the FEP, washing the results with IPA (mostly), having to keep the resin warm to get good results, draining the resin when not used for a while, faffing about with orientation and supports is a black art, etc.

The test site is severely damaged, and they don't have another one. It took what ,6 months to rebuild the launch tower after IFT-1? And it wasn't destroyed, just damaged, on the test site the tanks and pipes and all the rest are right near the vehicle so I see a lot of destruction.

So what, 6 to 9 months while they repair/build new test site(s)?

Might as well cut the losses and scrap Block 2 altogether, and move on to Block 3.

Interesting. Thanks for responding. As I've gotten older (or maybe it is the times and not me), I've found online conversation less stimulating, and like you, most of my IRL conversations are focused on more social/personal things. I've used LLMs for learning, but not conversation; but I've been scratching that itch with books, which, although they are not the same as conversation, do offer something similar.

My main problem with the movement is their emphasis on Bayesianism in conjunction with an almost total neglect of Popperian epistemology.

In my opinion, there can’t be a meaningful distinction made between rational and irrational without Popper.

Popper injects an epistemic humility that Bayesianism, taken alone, can miss.

I think that aligns well with your observation.

Also, Wix bought this guy with an impressive track record. There might be an earn-out that's not being discussed.

The article mentions that $25M is a retention bonus for those eight employees. (About $3M each — a nice bonus by any standard, but not insane for SV + AI. Presumably that's Wix stock, not cash.)

So the purchase price might be made up of components something like this:

- $30M for the client list

- $25M retention bonus to employees, with standard RSU vesting

- $25M for the founder, with earn-out goals over four years

He lives in a GenAI bubble where everyone is self-congratulating about the usage of LLMs.

The reality is that there's not a single critical component anywhere that is built on LLMs. There's absolutely no reliance on models, and ChatGPT being down has absolutely no impact on anything beside teenagers not being able to cheat on their homeworks and LLM wrappers not being able to wrap.

In Apple's quest for thinness and quiet they have made lots of undercooled devices that overheat and thermal-throttle and just plain die. That Dell replaced a MBP which replaced another MBP that had to have the motherboard replace 8 times before Apple forced us to sue them in a class action (and we won). If only they had just cooled the thing properly.

>there's a big market for small, efficient, silent laptops with good displays in the $2500+ range.

Yeah, it's called "apple fanboys", people with more money than sense who fetishize slimness and quiet over computing.

The Dell costs less than half the price of a $2500 fanless Apple laptop, so it's really no wonder Apple is forever at ~15% market share - most people prefer to not spend their money on Apple hardware. Price/performance is not what Apple is known for, they are a luxury brand, a status symbol. And that's great if that's what you need, Apple makes a laptop for you.

I want to turn on audio or video recording in a way that is not reversible.

Being able to start the camera without unlocking the phone is a good step, but you can also delete the footage just recorded if someone apprehends your device. I would be interested in the option to not be able to delete that footage.

I would also be interested in being able to live-broadcast (maybe just audio?) to someone else's device to prevent the evidence from being destroyed also without having to unlock your phone.

What's the impact on the file size?

Forgive me, as I'm not a heavy Voice Memos user, but I'm a bit confused by problem statement.

Voice Memos seem to be ordered chronologically, and named after the location where they were taken (unless manually named), which seems decent unless you star getting a ton.

From the Voice Memos app I can share them to Messages, Mail, etc. Is the issue that you wanted to be able to select a voice memo to share from within Messages, instead of the other way around? Or is this more for posting audio only to social networks that only support video, and having a waveform instead of a random video of something else?
Ask HN: For a team experienced with LLMs – Any concrete reason to use LangGraph?

Never used LangChain\LangGraph , saw the bad reviews about LangChain (albeit they are 1+ year old) - has anything changed? What can we do easier\faster with the framework rather than building our own pipeline? What unexpected things pop up, especially during maintenance, debugging and scale? Are there other frameworks you would recommend?

Curious why you chose C++? Were there aspects of other languages/ecosystems like Rust that were lacking? Would choosing Rust be advantageous for blockchains that natively support it (like Solana)?

To be clear: I don't mean to imply you should have done it any other way. I'm interested mainly in gaps in existing ecosystems and whether popular suggestions to "deprecate C++ for memory safe languages" (like one made by Azure CTO years ago) are realistic.

Thank you for the AMA. A few initial questions:

- Would it be possible to open source your DB in the future? I think there are challenges in blockchain analysis (e.g. internal transactions) that goes beyond the specific DB.

- Having used Chainalysis and others, your product seems superior based on your presentation. Which blockchains do you support?

- Is there a "HN Code" to test Prism?

Haven't printed this telescope but I have printed some pretty big things for example a front rack for my wife's bike.

It's on the 3rd version, the first one broke on small collision (the bike fell over while standing), the 2nd on a big collision (my wife hit a bus stop :/ ). The 3rd version survived several years of daily use including hauling stuff from the mall.

The key is to split the design into parts that need to be strong in 2 axis and can be weak in the 3rd axis (to work around the layer adhesion problems). So you print 4 walls laying flat not standing vertically. That plus including rope or zip ties for elastic connections where needed - and you can make stuff that is plenty strong enough for most daily uses.

I printed with PLA and PETG and both are ok - PETG is less stiff but handles direct sun better.

I feel like this is a fairly small investment on the scale of the semiconductor industry, although it would be large for a single company if we were talking about a single year. See, for example, https://wccftech.com/chinese-chip-giant-smic-shaken-by-tarif... US$7.5 billion in capex at SMIC this year. But SMIC is just the largest of dozens of Mainland China semiconductor firms, and a lot of that investment is going into cutting-edge strategic nodes, not 180nm stuff from last millennium.

Don't get me wrong, you need that stuff from last millennium—not just 180nm but also the 6 μm I suspect "foundational" actually refers to. You need power regulation, precision measurement, and RF frontends in analog, and analog can't scale down the way digital can. And TI actually retains a world-leading position in those chips, with better and cheaper ICs than anything out of Mainland China today. But it's potentially a game of chasing China's taillights.

SiGe might be an exception; even at 130nm, IHP's SiGe BiCMOS process can hit 450GHz oscillation frequency and 350GHz ft, so even at fairly coarse process node sizes, SiGe could be a strategic enabling technology for submillimeter communication such as Starlink, which is reportedly critical for weapons such as Ukraine's naval drones.

Since these things have lots of LEDs, my first thought was to put a range of different tiny delays on them to induce destructive interference, so that the off parts of one LED's flicker are the on parts of another, to smooth out the overall output.

Actually that's not true, my first thought was "just use a layer of phosphor excited by the LEDs", but fluorescent tubes do that and people used to make the same complaints about flicker, so.

Looks like "flicker index" is a useful(?) search term, anyway.

I would not be so sure. There are many fields where reductionism was applied in practice and it yielded useful results, thanks to computers.

Examples that come to mind: statistical modelling (reduction to nonparametric models), protein folding (reduction to quantum chemistry), climate/weather prediction (reduction to fluid physics), human language translation (reduction to neural networks).

Reductionism is not that useful as a theory building tool, but reductionist approaches have a lot of practical value.

Yeah, the whole community side to rationality is, at best, questionable.

But the tools of thought that the literature describes are invaluable with one very important caveat.

The moment you think something like "I am more correct than this other person because I am a rationalist" is the moment you fail as a rationalist.

It is an incredibly easy mistake to make. To make effective use of the tools, you need to become more humble than before you were using them or you just turn into an asshole who can't be reasoned with.

If you're saying "well actually, I'm right" more often than "oh wow, maybe I'm wrong", you've failed as a rationalist.
