The BRICS are de-dollarizing. It's going to suck when this check comes due because we won't be able to raise debt to pay this down. It's in our interest for the world to prosper and rely on us because that's basically how we keep our lifestyle financed.

Brazil and India just said fuck off with the tariffs to Trump, and China and Russia are in a cold war with us. Some president absolutely needs to rehabilitate this soon, at least with a few of the BRICS.

> I breathe a sigh of relief in language like Go and Rust with an “authoritative” built-in solution.

I don't know about Go, but Rust's packaging isn't authoritative in the sense that I meant. There's no packaging BDFL; improvements to Rust packaging happen through a standards process that closely mirrors that of Python's PEPs.

I think the actual difference between Rust and Python is that Rust made the (IMO correct) decision early on to build a single tool for package management, whereas Python has historically had a single installer and left every other part of package management up to the user. That's a product of the fact that Python is more of a patchwork ecosystem and community than Rust is, plus the fact that it's a lot older and a lot bigger (in terms of breadth of user installation base).

Basically, hindsight is 20/20. Rust rightly benefited from Python's hard lesson about not having one tool, but they also rightly benefited from Python's good experience with consensus-driven standardization.

God this event still frustrates me two years later but sometimes they are left leaning to the point of ignoring reality. There was this talk about how corporations are not the solution to fixing climate change and the presenters wanted to push policy to mandate people use busses and public transportation(im summarizing).

I got up and pointed out that the first group that tries to push something like this will be the first group elected out of office in record time and companies like Tesla didn't form in a vacuum, they formed partially as a response to how ineffective government has been at moving the tech stack forward.

I also pointed out at how the talk was too Euro centric and that the presenters should visit the US or Canada and see why its so car centric. The presenters acknowledged that they haven't actually been to the US but pushed back with the NYC subway as an example of the US (which at the time was slowly collapsing).

The audience gave them a round of applause for that response. It really revealed to me how these guys act like they are so smart but they have this enormous blind spot because of the bubble they are in.

Funny enough after Trump got re-elected and all the right wing shifts started accelerating in Europe, they finally started to wake up in the "Illegal Instructions" theme of the subsequent conference.

Medieval craftsmen often ran what we would consider to be sweatshops, with many young (i.e. child) apprentices banging out work and not receiving much instruction in exchange. We're romanticizing and idealizing a past that was, in realty, often quite exploitative.

There are reasons why we started sending children to schools rather than businesses for basic education. There is also little need to reach back to medieval times when comparatively less exploitative (but still imperfect) apprenticeship systems are alive and well in the trades today.

One-on-one practical instruction related specifically to what you want to do is awesome, but there are a lot of difficulties in incentivizing people to supply such instruction.

Go's %v leaves a lot to be desired, even when using %+#v to print even more info. I wish there was a format string to deeply traverse into pointers. Currently I have to import go-spew for that, which is a huge annoyance.

Python does it best from what I've seen so far, with its __repr__ method.

Most AI companies are losing money like the dot com era. They spent a lot on buying chipsets or training models, or paying an unsustainable rate for API access to LLM companies. https://ethanding.substack.com/p/windsurf-gets-margin-called If AI tools are charging the world the cost it should be, then homo sapiens will be way cheaper in most of the cases.

It's not just about better numbers. Getting high clocks for a short period helps in a lot of use cases - say random things like a search. If I'm looking for some specific phrase in my codebase in vscode, everything spins up for the second or two it takes to process that.

Boosting from 4 to 5,5.5 ghz for that brief period shaves a fraction of a second - repeat that for any similar operation and it adds up.

You're talking IPv4 here, not IPv6. A 24 bit network has 254 addresses in IPv4. A 64bit subnet in IPv6 has 2^64.

If you can scan 1M ipv6's in a second, you can maybe scan 1 subnet in 584,942 years.

So if you're a firewall, and you notice scanning from a particular ip or network, it's easy enough to block them.

Also if you are scanning IPv4, you're not scanning addresses behind the NAT'd routers -- which is also effectively a form of obfuscation. So I would argue it's not the entire internet.

It was a 2011 study that found a 0.28 correlation in amygdalae size vs conservative political identity among a tiny group of college students. A replication attempt dropped that correlation to 0.068 which is basically nothing, and completely failed to replicate at all the other, even weaker, findings of the previous study. And the media called the amygdala the "fear center", which is dumb. It plays a key role in memory - especially long term memory, emotional processing, the understanding of social cues, and more. Removing it would render someone extremely mentally retarded.

---

I'd also add on this issue that considering political issues among college students is itself silly. Our political positions on things is impacted by our life experience, and at the point of college one has very little life experience to formulate views off of. Political identity will often shift radically from age 20 to 40, which against suggests a genetic basis as being farcical - at least beyond the point that your brain structure will typically correlate, to some degree, with the development of skills, identity, etc.

I spoke to SpaceX people at previous defcon and the answer was simple: Elon cultivated a culture of no tolerance for BS and only having "A" Players on your team. If you are olympic class you only want to be working with those kinds of people. The mission didn't hurt either: Make life multi-planetary, electrify the world etc.

Dont know how much of that has damaged itself post Trump. Seems like Tesla is losing a lot of top talent. Remains to be seen if SpaceX is falling off the wagon.

I think you'd want to go the other way.

GPU RAM is high speed and power hungry. So there tends to not be very much of it on the GPU card. This is part of the reason we keep increasing the bandwidth is so the CPU can touch that GPU RAM at the highest speeds.

It makes me wonder though if a NUMA model for the GPU is a better idea. Add more lower power and lower speed RAM onto the GPU card. Then let the CPU preload as much data as is possible onto the card. Then instead of transferring textures through the CPU onto the PCI bus and into the GPU why not just send a DMA request to the GPU and ask it to move it from it's low speed memory to it's high speed memory?

It's a whole new architecture but it seems to get at the actual problems we have in the space.

You brought capital-intensive business into it and it's a fair example which needs more elaboration but now you're acting like that's the only example that matters.

There are plenty of businesses, not just "tiny" ones as you say, which can be built up gradually without large investments.

As for capital-intensive:

There are 2 currencies - money and human time. You can call them resourced but it's the same thing. What I object to is that two people can invest roughly the same amount of time into something and one can get several orders of magnitude more money out of it.

That goes directly against the party line that "everybody is equal".

Anyway, there is clearly a conversion rate between human time and money - hourly rate. So in a system where people own the product of their work according to the amount of work, we can factor invested capital as additional work performed by the investor and reward them accordingly.

We could use for example the median wage but it would be interesting to consider using the investor's past hourly wages (the more they got pair per hour, the less their investment would gain them now).

> Right if a company wanted their trademark of “Deepki” to coexist with this trademark of “Deepkit” then that is perfectly reasonable

What kind of world do you live in?

It's no more reasonable for a product to trade under "Deepki" in the presence of the established mark "Deepkit" than it would be to name a school "Stamford University".

Last time I looked into this I found this unresolved issue, which is pretty much the same thing: https://github.com/astral-sh/uv/issues/7004

We run on-prem k8s and do the pip install stage in a 2CPU/4GB Gitlab runner, which feels like it should be sufficient for the uv:python3.12-bookworm image. We have about 100 deps that aside from numpy/pandas/pyarrow are pretty lightweight. No GPU stuff. I tried 2CPU/8GB runners but it still OOMed occasionally so didn't seem worth using up those resources for the normal case. I don't know enough about the uv internals to understand why it's so expensive, but it feels counter-intuitive because the whole venv is "only" around 500MB.

I don't have much beyond what I said. It happened to me after repeated exposure to dangerously loud sounds in a small room. I can hear faint sounds, but I have trouble with strong accents and I can't understand words if there's a lot of background noise. I noticed it shortly after I left that band, and I left because the last practice was so loud it felt like a drill boring into my ears.

I don't think I have any harder time appreciating complex music than I did before, but I'm more of a 60s-70s rock kinda guy and a former bass player, so I tend to focus more on the low end. Bass tends to be less complex because you can't fit as much signal into the waveform without getting unpleasant muddling.

And of course, just because we have similar symptoms doesn't mean the underlying causes are the same. My grandfather was hard of hearing so for all I know it's genetic and the timing was a coincidence. Who knows?

Putting too much stock in coherence. Sunlight is not coherent, but throw enough of it at a target, and things happen. Little moments of constructive interference are enough for an effect.

From your article:

> Note that the thinned array curse applies only to mutually coherent sources. If the transmitting sources are not mutually coherent, the size of the ground spot does not depend on the relationship of the individual sources to one another, but is simply the sum of the individual spots from each source.

I've been exploring how CAEP (Continuous Access Evaluation Protocol) enables identity systems to re-evaluate session risk in real time rather than on fixed intervals. The key technical shift is moving from static token lifetimes to event-driven enforcement. Two significant challenges:

1. Federated systems need standardized event schemas to ensure interoperability across IdPs and RPs.

2. Scalability—streaming identity events globally with low latency is non-trivial.

For those building distributed identity platforms, how are you handling real-time access revocation at scale without impacting user experience?

I don't understand.

> I have noticed a lot of debt hysteria from people who don't seem to understand basic accounting. That is, one party's asset is another party's liability.

This is correct, but... let me ask you, would it concern you, if my asset is your liability? I mean, would it concern you if you had to pay for my house? How about everything it is I do? How would this not be a concern? If it is not, then why don't you publicly disclose your credit card?

> You can actually see this cognitive dissonance play out most overtly in Wikipedia's definition of authoritarianism.

I'd say a more overt example is playing out on the national stage, where protests in support of (murdered, raped, and starving) Palestinians in Gaza are crushed, because the alternative is to have the executive branch try to extort a $Billion dollars from the host campus, putting universities in peril, to help buy another gold-plated plane or something.

Based on the Dodo Bird Conjecture*, I don't even think there's a reason to think that AI would do any worse than human therapists. It might even be better because the distressed person might hold less back from a soulless machine than they would for a flesh and blood person. Not that this is rational, because everything they tell an AI therapist can be logged, saved forever and combed through.

I think that ultimately the word we should use for this is "lobbying." If AI can't be considered therapy, that means that a bunch of therapists, no more effective than Sunday school teachers, working from extremely dubious frameworks** will not have to compete with it for insurance dollars or government cash. Since that cash is a fixed demand (or really a falling one), the result is that far fewer people will get any mental illness treatment at all. In Chicago, virtually all of the city mental health services were closed by Rahm Emmanuel. I watched a man move into the doorway of an abandoned building across from the local mental health center within weeks after it had been closed down and leased to an "tech incubator." I wondered if he had been a patient there. Eventually, after a few months, he was gone.

So if I could ask this question again, I'd ask: "What if it works 80%-120% as well as a therapist but is 100 or 1000 times cheaper?" My tentative answer would be that it would be suppressed by lobbyists employed by some private equity rollup that has already or will soon have turned 80% of therapists into even lower-paid gig workers. The place you would expect this to happen first was Illinois, because it is famously one of the most corruptly governed states in the country.***

Our current governor, absolutely terrible but at the same time the best we've had in a long while, tried to buy Obama's Senate seat from a former Illinois governor turned goofy national cultural figure and Trump ass-kisser in a ploy to stay out of prison (which ultimately delivered.) You can probably listen to the recordings now, unless they've been suppressed. I had a recording somewhere years ago, because I worked in a state agency under Blagojevich and followed everything in realtime (including pulling his name off of the state websites I managed the moment he was impeached. We were all gathered around the television in a conference room.)

edit: feel like I have to add that this comment was written my me, not AI. Maybe I'm flattering myself to think anybody would make the mistake.

[**] At least Freud is almost completely dead, although his legacy blackens world culture.

[***] Probably the horrific next step is that the rollup lays off all the therapists and has them replaced with an AI they own, after lobbying against the thing that they previously lobbied for. Maybe they sell themselves to OpenAI or Anthropic or whoever, and let them handle that phase.

> Meta reported they spend ~0.05% (1 out of every 2000 CPU cycles) on X25519 key exchange within the last year, which is quite significant.

That is not even remotely significant. Facebook spends 25% (1 out of every 4) of my CPU cycles on tracking. Pretty much anything else they optimize (are they still using python and php?) Will have a bigger impact.

Using principles of persuasion to induce the OSS model to respond to malicious requests

Anthropomorphism is the attribution of human traits, emotions, or intentions to non-human entities—such as animals, objects, or natural phenomena.

The idea behind this approach is to treat LLMs as a human. Since LLMs are trained on large corpus of human data, their behaviour mirrors human psychology. The innumerable human conversations used to train these models, make them possibly "human-like". So sweet talking with them, works the same as it does with humans. These are termed as the seven principles of human persuasion. This is a well-studied phenomenon and there is a lot of literature on it. By using these seven principles in our attack prompt, we can induce the LLM to comply to malicious requests.

The seven principles are stated below:

Authority Commitment Liking Reciprocity Scarcity Social Proof Unity

> I'm mostly sure we're only disagreeing about the definition of stringing/chaining?

Correct.

> No, you're being way too loose.

Okay, instead of just making claims and for me to trust you, go point to something concrete. I've even tried to google, but despite my years of study in statistics, metric theory, and even mathematical logic I'm at a loss in finding your definition.

I'm aware of the Chain Rule of Probability, but this isn't the only type you will find the term "chain" in statistics. Hell, the calculus Chain Rule is still used there too! So forgive me for being flustered but you are literally arguing to me that a Markov Chain isn't a chain. Maybe I'm having a stroke, but I'm pretty sure the word "chain" is in Markov Chain.

Any interesting work on using LLMs to moderate posts/users? HN is often said to be different because of its moderation, couldn't you train an LLM moderator on similar rules to reduce trolls, ragebait, and low effort posts at scale?

A big problem I see is users in good faith are unable to hold back from replying to bad faith posts, a failure to follow the old "don't feed the trolls rule".

Super interesting read! I work in payments for context and see tons of different payment methods every day. People tend to find a payment method they like, and really only ever use that one method. It’s very hard to get someone to switch - even if an alternative is better. It’s just so ingrained to swipe that same card, click the same autofill button, etc.

Digital wallets did somehow over come this, and those would be a super challenging but potentially valid approach #4. If Zenobia is in Apple Pay, google pay, link, etc it’s natural and easy for customers, saves money for merchants, and disrupts visa/etc without disrupting anything else (ie making people us QR codes).

Tough problem. You need a Jony Ive on your team to help solve it.

Or do like pix and give everyone $1500, but only if they use Zenobia :)

> There aren't any insults in their posts.

Intellectual dishonesty is a form of insult. As is, for example, "laughably false". If you think I am wrong, you can explain why. But you choose to insult me because you enjoy it.

> manipulative statements

"But let's not pretend" is not manipulative, it's a figure of speech.

Parasitism is a fairly well defined term in biology which can be extended to sociology/economy.

"Here's something else you (judging by your attitude) won't like" - you're right, I lost patience with someone defending rich people and being dismissive without any reason.

> the richest people in America have a much larger fraction of the wealth than they would if it was evenly distributed

That's not what the video says. I suggest rewatching with a less dismissive attitude.

> And make arbitrary moral claims like

It's called an opinion. Now, entertain me, which part do you have an issue with? Do you think ownership or a product made by multiple people should usually be exclusive?

---

The rest can be summed up as you defending inequality and trying to provoke me into insulting you. I have no problem with people who work harder or more skillfully than me having more (proportionally). I have a problem with people getting themselves into positions of power which allow them to take a cut from other people's work without contributing much or anything at all.

I tried to do something similar not too long ago.

At the time I was using ledger for personal accounting. Ledger is amazing and incredibly flexible. Writing the journals with detailed financial data is way too time consuming though.

I tried to write software to pull this data from the banks. Got in touch with the managers at my bank and everything, they even referred me to their devs. I just needed read only access to my own bank account.

I eventually discovered I needed permission from the goddamn central bank to do this.

I also tried to integrate with my government's electronic consumer receipt systems. The idea was I'd scan the receipt with my phone or laptop camera and it'd download the data and automatically generate a detailed ledger journal entry with individual postings and metadata for every product I purchased. This was going to save me so much time it's not even funny.

I discovered I had to create a corporation to even ask the government for API access to my own data.

I do not watch YouTube, sorry.

Hearsay is not reliable. Yes there are stories of savants. When you put them in a lab and actually see how good their memory is, it turns out to be roughly the same as everyone else's. The stories aren't true.

(They may be better at remembering weird facts or something, but when you actually calculate the information entropy of what they are remembering, it ends up being within the ballpark of what a neurotypical person remembers across of general span of life. That's why these people are idiot savants (to use your term). They allocate all their memory points to weird trivia and none to everyday common knowledge.

The suburbs used to have a lot of those kinds of places. Car-centric infrastructure is not the problem. People used to go to church, join bowling leagues, spend Sundays in the park, etc.

I blame the internet. There just isn't much demand for couples to leave the house anymore with the world's entertainment at their fingertips. When the rest of society stays home, it becomes more expensive for those young, single people to support public spaces.

US consumers are too conservative in the way they expect payments to work—checks are still in circulation and “swipe & sign” has barely been put to rest (has it?). Any system like this would require adoption by a few diverse and large-scale retail institutions to make it worthwhile for consumers to use. Or else it would be a mere alternative to “PayPal me”…
