Use stairwaytogray, find a supplier with a history of many many 99+% purity reports from 3rd party testing sent to janoshik, then order 20 vials from that supplier, then either send a vial to janoshik yourself or participate in a group buy test (or just wait for someone else to test the same batch. At that point, it is very likely your ampoules have the same purity and amount. The best supplier seems to currently be sigma audley.

This tracts, but I think women are evaluating men in “TikTok” metrics, instead of qualities that make a man a great partner.

For example, being over 6ft doesn’t make you a good dad. Or being physically attractive, doest’t make you a supportive partner.

If anything, these characteristics make a man worse, as men in these categories tend to have the pick of the litter, resulting in many women frustrating and disappointed in men if they weren’t selected.

It means nothing (musically speaking, in my opinion).

Vulfpeck published an empty silence album to it and it got significant playtime due to social media antics.

These worries are more related to the money aspect of music. It is a tragedy and impacts an important aspect of the music ecosystem, but not very relevant to music itself.

This tragedy predates AI by decades, it started with Napster, it won't be stopped anytime soon, and there's little point discussing it anymore.

In a sense, the AI thing is feeding on the tragedy to promote itself, which is a disgusting act if you think of music and commerce as traditional aspects of human life.

> And it is insane to me that I'm now seeing this "oh actually teen pregnancy wasn't so bad" thing pop up all over the place.

The other side of this is insane to me... the "oh actually looming human extinction won't be so bad" thing. Sub-replacement fertility rates are slow-motion extinction. Animal models where they "bounce back" is irrelevant, those animals have their extremely high above-replacement fertility all through their famines, plagues, and predator massacres such that when those pressures relent their population recovers. There's no known precedent for raising fertility rates that fall let alone so low.

I do think there are some existing mainstream facing consumer AI applications out there. Macrohive touts AI tools, although that's wider than daytrading.

Well, that's what I spend a good amount of time doing, and no, these things aren't going to spontaneously generate alpha and give "stock picks." Well, some of the deeper concepts can probably help do so, but then you're competing against hideously massive budgets in the same arena.

That said I do think that these tools could be a huge help to "daytrading". They could help with the screening and idea generation process. The concept of "factors" or underlying characteristics which drive correlation within certain baskets of instruments, is already well established in the finance industry. And indeed that concept can be widened out beyond the purely academic lens, so you may have a basket of interest rate sensitive names, or names that are one thematic hop away from a meme sector that is taking off. LLM style tools would be great there. Ex: I remember during COVID that for a week mask companies were taking off. One of these names also had a huge run up during the SARS epidemic. Pretty basic LLM style tools would be great at pointing stuff like that out, generating lists of equities which had unusual activity during pandemics within the last 20 years, etc. Much better than hard coding in filters to an old school screener.

Oh, I think machine learning is also being used in Nowcasting. That's where you take the current economic situation, compare it to previous regimes, and then sort of map out of probability distribution for likely forward paths. Good AI workload. I actually think it would be pretty cool to see something like that intraday (if large tech stocks are liquidating which of these smaller momentum tech names on my watch list have been resilient recently?). The thing is there's sort of the retail trading space, where most of the tools are fluff, and then the hardcore space where software engineers are working in OCAML and databases and have absolutely no need for more "presentable" tools. In daytrading, there is a big gap inbetween thet, and it's surprisingly empty.

In Global Macro/portfolio managent adjacent areas (ex: NowcastingIQ.com, was browsing that earlier today thus my thoughts on the matter) you can find humans who don't know how to code who want to use these tools and can afford $25,000 a year, but again in Daytrading - the actual intraday trading stuff that makes real money - there's less of an illusion that it isn't a robotic warzone.

The article has ownership information in Backstage is getting out of date and I'm wondering about how that happens for them. Obviously that'll happen if the system doesn't talk to other systems, but (for better or worse) my company's systems connect to LDAP/Entra and access gets granted via group membership. Thus the foo service's admins are in the foo-service-admin group in order for them to have whatever non-backstage admin access their role requires. If the foo service is in the middle of an incident, at the worst you'd start paging the people in that group, no?

Yes, that's true, but bullet point ideology isn't very useful imo.

For example you can easily sum up "How to Win Friends and Influence People" into a few short recommendations. "Empathize with people, listen closely to people, let them do most of the talking, be quick to be upfront and honest with your faults." But it gets tenuous and some of the exact meaning is lost, and the bullet points aren't very convincing on their own of the effectiveness of the recommended methods.

The book fleshes out the advice with clarifications as well as stories from Carnegie's life of times he used the techniques and their results.

I think humans are good at remembering stories. For example I always remember the story about him letting his dog off the leash in a dog park and how he leveraged his technique for getting off the hook when a cop confronted him about it. I think I remember that better than the single bullet point advice of "readily and quickly admit when you're wrong." In fact I think the end of each chapter succinctly states the exact tip and I'm sure I'm misstating it here.

I could use anki to memorize a summary but I don't think I'd be able to as effectively incorporate the techniques into my behavior without the working examples, stories, and evidence he provides.

And that's just non fiction. I can't fathom the point of summarizing a fiction book, whose entire enjoyment comes from the reading of it.

Yes? I agree "geo" and "region" are synonymous here, but as I understand the word "blocked" to be "blocked" a transaction has to be in action in the first place - and if one party to the transaction (steam) isn't interested then the transaction wasn't in action.

Similarly you can block a punch, but not if it was never thrown.

"Significance: In terms of syntax and semantics we don’t see much of COBOL in modern computing."

Would I be wrong in saying that SQL has what feels to me to be a very cobaly syntax. By which I mean, I know it is not directly related to cobal, But someone definitely looked at cobal's clunky attempt at natural language and said "that, I want that for my query language"

Yes. Logue's are (brilliant) retellings, not translations. His source material were other English translations, since he was not literate in ancient Greek (as the article's author notes).

----------

See an East African lion Nose tip to tail tuft ten, eleven feet Slouching towards you Swaying its head from side to side Doubling its pace, its gold-black mane That stretches down its belly to its groin Catching the sunlight as it hits Twice its own length a beat, then leaps Great forepaws high great claws disclosed The scarlet insides of its mouth Parting a roar as loud as sail-sized flames And lands, slam-scattering the herd.

“This is how Hector came on us.”

It's not just about sensitive data like passwords, contracts, or IP. It's also about the personal conversations people have with ChatGPT. Some are depressed, some are dealing with bullying, others are trying to figure out how to come out to their parents. For them, this isn't just sensitive, it's life-changing if it gets leaked. It's like Meta leaking their WhatsApp messages.

I really hope they fix this bug and start taking security more seriously. Trust is everything.

I can't ignore the profound degradation in the American standard of living as a contributing factor, especially in the last ~5 years (the recent housing bubble and "transitory inflation" (remember that one?) being disproportionate contributors.

This is paired with the lack of stability in employment seemingly across sectors and general economic uncertainty.

I hear concerns like the following, across social groups:

"I'm 'paid well' but live in this dusty old apartment building that's, at most, 700 sq ft."

"If I lose this job, what's the likelihood I make the same amount to even afford this? How long will the job search take?"

Few other things: I pay more for car insurance now than I did when I was in my early 20s, despite driving a far slower, more pedestrian car. Food prices are laughable, even rent far out from major employment centers is much much more than it was even in the late 10's, etc.

I think all of these are major factors that almost noone is immune from.

Almost everyone I know will express some sort of exasperation and lack of security related to the above. These are not the conditions that motivate people to have kids.

I am no expert in the field, but my reading of the original rowhammer issue (and later partial hardware mitigations) was that it was seen as better to design RAM that works fast and is dense and get that to market, than to engineer something provably untamperable with greater tolerances / die size / latency.

GPUs have always been squarely in the "get stuff to consumers ASAP" camp, rather than NASA-like engineering that can withstand cosmic rays and such.

I also presume an EM simulation would be able to spot it, but prior to rowhammer it is also possible no-one ever thought to check for it (or more likely that they'd check the simulation with random or typical data inputs, not a hitherto-unthought-of attack vector, but that doesn't explain more modern hardware).

Houdini is entirely a node-based system and HDAs are just your custom nodes (on contrary to the built-in ones).

At the end of the day, an HDA is just a 'function' you define like what you do in a programming language. A function can call other functions etc. It might sound nothing special if you're a programmer, but Houdini is the only generic DCC that is built around this idea, making it more like a framework than an app.

> I see so many people loving Gibson and crediting him for inventing the genre whole cloth, but of course he didn't! None of us write anything without standing on the shoulders of those who came before, building on the works and ideas of those that came before.

Not defending him or speaking for him, but based on his Paris Review interview, I think Gibson would be the last person to claim he invented the genre; he was trying to do something inside of science fiction, and instead science fiction "othered" the thing he was doing by calling it a sub-genre and continuing going on doing the science fiction writing they were already doing.

The article claims that cyberpunk and "Neuromanticism" are distinct, with the "Neuromantics" coming out and doing the same thing as Neuromancer, without the cyberpunk ethos being there underneath.

> The leaked responses show clear signs of being real conversations: they start with contextually appropriate replies, sometimes reference the original user question, appear in various languages, and maintain coherent conversational flow. This pattern is inconsistent with random model hallucinations but matches exactly what you'd expect from misdirected user sessions.

A model like GPT-4o can hallucinated responses that are indistinguishable from real user interactions. This is easy to confirm for yourself: just ask it to make one up.

I’m certainly willing to believe OpenAI leaks real user messages, but this is not proof of that claim.

> Tons of ways to compromise it between your computer's USB port and the server's database, though. If you already have dedicated hardware, FIDO authenticators make much more sense.

I mean, if you have the amount of access needed to compromise a USB connection, you have way more than enough access than needed to just yoink the authentication token or encryption key from browser storage.

A classic medieval university education wasn't theology or reading Greek and Latin literature like epic poetry. It was the Trivium and Quadrivium, which emphasized logic, math, and astronomy, along with analytical writing skills so these ideas could be synthesized and communicated. What we today consider a classical, humanities-based education began to form, I think, near the start of the Renaissance, which in many ways was a reaction to the overly science-based curricula.

The highest degrees were in law, medicine, and theology, but these were professions and prerequisites for the same; i.e. professional degrees, much like today[1].

[1] I'm curious what percentage of those obtaining masters and doctorates in theology today go on to work as pastors, and specifically if still[citation needed] a majority.

One other important detail is that money smooths a ton of things over. Cooking dinner is less onerous when you have a decent kitchen, good ingredients, and it’s not taking time you need to clean the house, fix the car, etc. because you outsource that. That doesn’t mean that affluent marriages are always happy, of course, but the odds are better with less stress.

Mellanox already kind of controlled Infiniband so Intel/QLogic could either chase Mellanox or fork and IMO forking into Omni-Path wasn't necessarily a bad choice. Omni-Path got zero adoption but that could have been for any number of reasons.

So many customers have a mental block against anything that isn't called Ethernet so the industry cannot "just use Infiniband"; they really had no choice but to create UEC. I would predict that Broadcom ends up de facto controlling UEC since their market share is much higher than Nvidia and people now want anything but Nvidia to create competition.

Just to share one datapoint - I have not looked at the internals myself, but having talked to a couple of devs who has spent a great deal of time working with Blender at a code level, one takeaway seemed to be that there was a lot of code duplication caused by each dev doing their own thing and not having an overall architect to rationalize some parts of the code.

A particular example that was mentioned was the importers that were each done standalone rather than built on a common framework. This was a couple of years ago and of course things may have changed since then.

Just to note that the developers were still extremely positive about working with and in the code, but it does seem plausible that there would be issues like this in a codebase where many devs focus on a small piece of the overall puzzle.

The claim that “tourism has little financial benefits to the local economy in Venice” is debatable and context-dependent. Here's a detailed breakdown addressing both why the claim may be true in some aspects, and why it may be misleading or false in others.

---

Arguments Supporting the Claim:

1. High Leakage of Tourist Revenue

Much of the tourist spending in Venice ends up outside the local economy:

Many hotels, cruise lines, and travel agencies are owned by foreign or non-local entities.

Revenue often flows to large tour operators, not to Venetians themselves.

Day-trippers (especially cruise passengers) spend very little per capita.

2. Overtourism and Cost Externalization

The externalities of mass tourism (e.g. garbage collection, water bus crowding, maintenance of ancient infrastructure) are borne by the municipality and residents, not by tourists.

The economic cost of wear and tear on fragile historical structures is immense and undercompensated.

3. Loss of Local Businesses and Services

Traditional shops and services (bakeries, fishmongers, schools) are being replaced by souvenir shops and Airbnbs, which often serve short-term tourists.

This creates a "hollow economy" where real life becomes unviable for locals.

4. Depopulation and Real Estate Inflation

Real estate is increasingly purchased by investors for short-term rentals, pushing locals out and reducing residential density.

Venice’s population has dropped from ~175,000 in 1950s to under 50,000 today in the historic center.

5. Low Multiplier Effect

Much of the employment created is low-paid, seasonal, precarious, and lacks career development.

Limited reinvestment into the community fabric (education, public health, sustainable infrastructure).

---

Counterarguments (Why Tourism Still Brings Economic Benefit):

1. Tourism Is a Major Employer

A significant portion of Venetian jobs is in hospitality, transport, and retail, all tied to tourism.

Completely removing tourism would collapse the current local job market.

2. Tax Revenues

The city imposes tourist taxes (tassa di soggiorno) on accommodations and more recently, even entrance fees for day-trippers.

These can help fund infrastructure and conservation—if well-managed.

3. Export Substitute

Venice doesn’t have a diversified industrial base. Tourism is one of the few export-equivalent services Venice can offer due to its geographic isolation and fragile ecosystem.

---

Conclusion

While tourism contributes significantly in gross economic terms, the net local financial benefit is undermined by:

revenue leakage,

rising costs of living,

poor job quality,

and infrastructure stress.

Thus, the statement is partially true: mass tourism as currently structured in Venice is unsustainable and offers diminishing marginal returns to locals, especially compared to the burdens it imposes

It’s strange to see that anecdote so highly upvoted when it’s so trivial to look at birth rates by parental age.

Reduced teen pregnancies are not the driving factor in recent fertility rate declines at all.

It is interesting how an appeal to emotion with a difficult story can lead so many to overlook the obvious shortcomings in that explanation. Honestly this entire comment section has a lot of people making guesses or putting forth their own theories without having even skimmed the article.

What do you mean by front office trade tools? neural networks, predictive models and fancy pants math has been used in trading stocks for 40 years. That's what the Medallion Fund is based on and it generates bonkers returns.

I feel that what was missing is exactly AI front office trade tools. The trading pros who wanted a black box investing style, i.e: the math says buy stock X so buy stock X, have had the option to do that with the knowledge that it's extremely effective based on the Medallion Fund returns. That's compared to a more traditional Warren Buffet-like style of valuing a business or even a more Michael Burry-like style of finding missed gaps for a collapse.

What was missing all these years is what this is. A way for someone who doesn't know much about investing (or doesn't have the time) to "just past data there and ask it is this a good investment" like other esteemed HN members mentioned they are doing.

The objective is always to attain some kind of synergy between the business logic and, as others have said, algorithm simplicity. The best way to go about it is to start from the chosen language/environment/library, and build out a DSL that can express the business rules. That's the basic premise of DDD, but where all this got complicated is splitting into contexts and the translation between their boundary.

I believe programmers should learn a bit about programming language theory, mostly the bits about what is a language. Then how to recognize the things behind the labels, and how they morph (either from an operation or from a translation between contexts). Then it's a matter of using the knowledge to move from the environment to a DSL that can express the business rules.

Architecture is the draft for the above, defining the starting point and a direction. And design is where you start to make decisions following the plan. For someone that have an idea of the destination, they can judge both.

It clearly is a 100% custom UI logic implemented by OpenAI… They render the products in carrousels… They probably get a list of product and brand names from the LLM (for certain requests/responses) and render that in a separate UI after getting those affiliate links for those products… its not hard to do. Just slap on your affiliate ID to the links you found and you are done.

This has already been discussed heavily in this thread:

https://news.ycombinator.com/item?id=44522772

Link to the full paper: https://metr.org/Early_2025_AI_Experienced_OS_Devs_Study.pdf

Overall the study is a very small sample size (16), with mixed AI tooling and mixed AI experience. It's an interesting data point, but honestly not an extensive enough study to make any causal determination. It's certainly plagued by much of the discourse around AI being highly polarized, as well as AI being such a broad category as to have little meaning overall.

Quoting from the above thread:

> My intuition here is that this study mainly demonstrated that the learning curve on AI-assisted development is high enough that asking developers to bake it into their existing workflows reduces their performance while they climb that learning curve.

The above quote, very much matches my personal experience. The first month or two was very hit or miss, and plagued with frustration. As I got better using the tools, and figured out new workflows, and settled on better tools, it's become a much better experience for me. Specifically, asking ChatGPT or Claude to generate a function for me sucked, editor tab completion with a good model was better, but still occasionally frustrating, chat in cursor was better than that, and claude code as an agent has been fantastic. But the journey was long and required a lot of reading, video watching, and listening to podcasts about how people who are successfully using AI coding tools work.

Currently I feel like I'm about 2x as productive (note: I'm not a particularly quick developer, so YMMV).
