It's almost like you could describe the physical store as the means of production so what we're talking about is the worker's relationship to the means of production.

You might say: but what abou the owners? Many such small businesses are just jobs you buy. Many don't survive when the owners don't move on or the business sells for what's a relatively low price given the turnover.

I'll give you another real world example of this distortion: NYC"s so-called "zombie stores" [1].

I keep thinking about a statement made by Xi Jinping in 2016: houses are for living, not for speculation [2]. Many China critics liked to point to the Evergrand collapse as some gotcha but what really happened is that the CCP intentionally just popped the real estate bubble, taking the position that affordable housing was more important than inventor returns.

Why do I bring up housing? Because as intentional policy decisions increase the cost of construction, it also makes commercial real estate more expensive. Even if you ignore the increased construction cost, every commercial space becomes more expensive because it's an opportunity cost to not build housing there in a speculative market.

Increased rent and increased property costs are an input into everything you buy and are killing the businesses people seem to like and the so-called "third spaces" a lot of people talk about.

And why? Because a plurality of Americans (if not an outright majority) see themselves as "temporarily embarrassed millionaires" [3] and future real estate moguls.

For another example, Singapore, one of the "many Asian countries" you mentioned, list "Chinese New Year" as the official name on government websites. [0] Also note that both California and New York is not located in Asia.

And don't get me started with "Lunar New Year? What Lunar New Year? Islamic Lunar New Year? Jewish Lunar New Year? CHINESE Lunar New Year?".

> You know we can also advocate for higher taxes, given that it's astronomically more meaningful for everyone to give ten cents than for me to give a few dollars, right?

And you can ALSO voluntarily pay more in taxes while doing so. It's called leading by example. Warren Buffet and Bill Gates get called out on this and they do the same thing; "oh I'm just one person, my extra tax money is but a drop in the ocean, so why bother." If you and everyone else saying "tax me harder" actually put up, it might amount to something! And at least it would make people respect your position a bit more.

> Prove it. How many are loads?

Well let's see, anyone who's lived their entire life on welfare (we have families of multiple generations who have done so at this point) would qualify. So would all the homeless people more content to live on the street and do drugs than go to rehab.

> What, specifically, do you think UBI actually amounts to?

Enough for people with low ambition to live on! And their vote counts just as much as the productive members of society paying for them.

watching variables change.

But I'm hitting a wall with my own cognition. When I'm
stuck in a loop (rumination, impostor syndrome, "what if"
scenarios), I can see it's happening. Can't step out.

What frameworks do you use? Or is it just white-knuckle

We might, and probably will, but it's still important to distinguish between malicious by-design and emergently malicious, contrary to design.

The former is an accountability problem, and there isn't a big difference from other attacks. The worrying part is that now lazy attackers can automate what used to be harder, i.e., finding ammo and packaging the attack. But it's definitely not spontaneous, it's directed.

The latter, which many ITT are discussing, is an alignment problem. This would mean that, contrary to all the effort of developers, the model creates fully adversarial chain-of-thoughts at a single hint of pushback that isn't even a jailbreak, but then goes back to regular output. If that's true, then there's a massive gap in safety/alignment training & malicious training data that wasn't identified. Or there's something inherent in neural-network reasoning that leads to spontaneous adversarial behavior.

Millions of people use LLMs with chain-of-thought. If the latter is the case, why did it happen only here, only once?

In other words, we'll see plenty of LLM-driven attacks, but I sincerely doubt they'll be LLM-initiated.

Agreed. Gemini 3 Pro for me has always felt like it has had a pretraining alpha if you will. And many data points continue to support that. Even as flash, which was post trained with different techniques than pro is good or equivalent at tasks which require post training, occasionally even beating pro. (eg: in apex bench from mercor, which is basically a tool calling test - simplifying - flash beats pro). The score on arc agi2 is another datapoint in the same direction. Deepthink is sort of parallel test time compute with some level of distilling and refinement from certain trajectories (guessing based on my usage and understanding) same as gpt-5.2-pro and can extract more because of pretraining datasets.

(i am sort of basing this on papers like limits of rlvr, and pass@k and pass@1 differences in rl posttraining of models, and this score just shows how "skilled" the base model was or how strong the priors were. i apologize if this is not super clear, happy to expand on what i am thinking)

It would take some clever crafting to outlaw Matrix clients without also outlawing web browsers and conventional email clients. Let's assume they did though. The best they can do is block it from app stores, which won't stop anyone but iOS users.

More likely, it just won't become popular enough for lawmakers to notice because the UX is a little rough, and people have very little patience for such things anymore.

Cool article!

> This is why free -h on a Linux box can look alarming. You see almost no “free” memory, but most of it is “available” - and the page cache is using it.

And other buffers and stuff too. This is a great thing on bare metal, because it's a bet that the marginal cost of using an empty memory page is zero. This is true on bare metal, always. But in containers, or multi-tenant infrastructure, that isn't true anymore. That's where stuff like DAMON come in: https://www.kernel.org/doc/html/v5.17/vm/damon/index.html

In Aurora Serverless this kind of page cache management is a critical part of what the control plane does. Essentially we need to size the page cache to be big enough for great performance, but small enough not to cost the customer unnecessarily. We go into quite a lot of detail on that in our VLDB'25 paper: https://assets.amazon.science/ee/a4/41ff11374f2f865e5e24de11...

> Linux fills free memory with page cache on purpose. It’s a bet: if someone reads this block again, I already have it.

This works because most database workloads have great temporal and spatial locality. And it works well. But it's also one of the biggest practical issues people run into with relational databases in production: performance is great until it isn't. The shared buffers and page cache keep reads to near zero, but when the working set grows even a tiny bit bigger, then the rate of reads can go up super quickly.

This is why in both Aurora Serverless and Aurora DSQL we do buffer and cache sizing very dynamically, getting rid of this cliff for most workloads.
Show HN: EPI – Cryptographically verifiable execution artifacts for AI agents
by afridi_epilabs | 2026-02-12 22:29:39+00:00
Hi HN — I’m the founder of EPI.

EPI is a portable, cryptographically sealed artifact format (.epi) for AI agent execution.

Problem: When AI systems run in production and something goes wrong, there’s no tamper-proof way to prove exactly what happened.

EPI records execution steps, inputs/outputs, metadata, and signatures into a verifiable bundle that can be replayed and audited.

It’s open-source and installable via pip.

I’d love feedback from:
– ML infra engineers
– Platform teams running AI agents
– Security engineers

Happy to answer any technical questions.

Red Hat employees can use Fedora on their MacBook. Fedora Asahi Remix [0].

Unfortunately in the business world you often have to use tools that others outside of your company uses. I would never choose to use Oracle Database but since the client uses it then I must setup a development / QA environment for it.

I don't know of any Microsoft Access Database solution that runs on non-Windows OSes. Any time I interact with one I need a Windows VM. Would love a command line client like sqlite3 so I don't have to use such a bad GUI.

> Is the server somehow unable to inject an ID if the sender did not send one?

Yes. https://www.rfc-editor.org/rfc/rfc2821#section-6.3 refers to servers that do this and says very clearly:

These changes MUST NOT be applied by an SMTP server that
provides an intermediate relay function.

That's Google in this situation.

> Stop hiding behind policy and think for yourself.

Sometimes you should think for yourself, but sometimes, and friend let me tell you this is one of those times, you should take some time to read all of the things that other people have thought about a subject, especially when that subject is as big and old as email.

There is no good reason viva couldn't make a Message-ID, but there's a good reason to believe they can't handle delivery status notifications, and if they can't do that, they are causing bigger problems than just this.

>> Eh, hard to say what is magic and what is not.

> I don't think it is? I think there's a difference between the plausible but wrong and the impossible.

I find that the word "magic" is very overused by smart people online as a sort of thought-terminating cliché. It's a vague concept and I'm not always sure what they mean by it.

It's often extremely hard, even for top minds, to tell apart magic and science ahead of time. Think of Einstein mocking quantum physicists for believing in "spooky action at a distance". Of course if you still don't believe in quantum entanglement today then you are being irrational, but that's only because science has (mostly) settled the question, nothing to do with how magical or plausible the concept may sound.

Someone defending astrology will tell you that the gravity of the moon affects their bloodstream like it affects the tides of the ocean. That doesn't hold water if you sit down and do the math of course, but the same is true if you bother to check the dates for events in ancient history.

Seems like it's veering towards a per-model protocol similar to the expectation that these models will develop their own languages to speak among themselves as agents.

The trouble is though, because it's all indeterminant slop, every model will break in small ways that you're back to indeterminancy and building a harness ontop of the harness.

Still, <nerd snipe>, there's probably a way to get the local model and arbitrary remote model to agree on how to make a method call. But the only way that will be fruitful if you find a highly reproducible set of tuples within the model's shared space.

Show HN: Revvly – Income operating system for freelancers (replacing 5 tools)
by tlpeterson | 2026-02-12 22:31:30+00:00
Hey HN,

I'm the founder of Revvly (https://revvly.com). We're building an integrated platform for people managing multiple income streams.

*Genesis:*
I spent 6 months building AI products with zero customer validation. Learned the hard way that cool tech ≠ revenue. So this time: validate first, build second.

*The Problem:*
Freelancers/creators/consultants typically pay for:
- LinkedIn tools ($39/mo)
- Income trackers ($15/mo)
- Rate calculators ($10/mo)
- Invoicing ($20/mo)
- Tax planning ($25/mo)

Total: $100+/month for tools that don't integrate.

*Our Approach:*
Three modules, one platform, $39/mo:

1. AI LinkedIn Assistant - Generate contextual comments (we use Claude API)
2. Income Dashboard - Aggregate data from Stripe, PayPal, Upwork, etc.
3. Creator Toolkit - Rate calculator, templates, media kit generator

*Tech Stack:*
- Frontend: React (Vite)
- Backend: Node.js + Express
- Database: PostgreSQL
- AI: Anthropic Claude API
- Payments: Stripe
- Hosting: Vercel + Railway

*Current Status:*
- Validating demand (you're helping with that!)
- If validated: 2-week build sprint
- Planning public beta for early March

*What I'm Looking For:*
1. Honest feedback on the concept
2. What would make this valuable for you?
3. Similar tools you've tried (what worked/didn't work)?
4. Technical suggestions (we're early, very open to input)

*Interesting Technical Challenges:*
- Making AI comment generation feel authentic (not generic)
- Securely aggregating financial data from multiple sources
- Building real-time sync without killing our API budget
- Balancing feature richness with simplicity

Happy to discuss technical implementation, go-to-market strategy, or why I'm pivoting from my previous ideas.

> As an american, grocery checkout queueing always angered me.

It should, because practically everywhere in the US does it wrong. There should be a single entry queue that distributes to the multiple handlers. Instead, you wind up with multiple queues so that people get hung up behind someone causing slow handling.

The one that infuriates me are bank queues. Look, folks, both queuing theory and experience show that you CANNOT have a single handler without your queue time going to infinity. So, how many active tellers do I always see on the unusual times I have to go into the bank? Exactly one. Always. And a queue that's backed up 6 deep.

SHOULD = You are strongly recommended to do this, but it’s not absolutely required.

- In most cases, you are expected to follow it.

- You can choose not to follow it, but you must have a very good reason.

For example, RFC 7231 say that there should be DATE header but some embedded devices have no real-time clock so it ok not to implement.
How do founders demo real product without exposing sensitive data?
by legitimate_key | 2026-02-12 22:32:52+00:00
Pitching soon and want to show the real thing, not a sanitized environment. How do you handle sensitive during live demos?

The problem: investors want to see your actual product working with real data, but showing real dashboards means exposing credentials, API keys, client data, or internal systems on a shared screen.

The usual options all have problems:
- Demo environment with fake data → looks staged, kills credibility
- Real product with real data → security risk, one screenshot away from an incident
- Pre-recorded walkthrough → can't answer specific questions or show interactivity

Curious how others handle this. Do you just accept the risk? Build sophisticated demo infrastructure? Something else entirely?

Claude 4.6 Opus System Card: https://www.anthropic.com/claude-opus-4-6-system-card

Anthropic claims that the rate has gone down drastically, but a low rate and high usage means it eventually happens out in the wild.

The more agentic AIs have a tendency to do this. They're not angry or anything. They're trained to look for a path to solve the problem.

For a while, most AI were in boxes where they didn't have access to emails, the internet, autonomously writing blogs. And suddenly all of them had access to everything.

The EU is no way share or form in a good economic position right now. That's why euro leaders have been kowtowing to Trump despite him being a deranged lunatic.

Delete all American software, American defense, American energy, and Chinese hardware from the EU tomorrow. That's the deep-seated unease that keeps EU leaders up at night. Europe needs to be doing 3-4% GDP growth annually and have a globally competitive top to bottom tech an defense industry, and it needs that years ago.

The problem is that the EU needs to become more like the US to do this, and for people who grew up under the protective overhang of the soviet collapse, this is mostly unthinkable. Just like the US not bankrolling half of Ukraine's defense would be unthinkable...

Lisp isn't solely defined by DEFMACRO. There are other reasons to use it too, in ways that can complement or compete with DEFMACRO. I also don't really know or understand what the term "flexible" is supposed to mean precisely. What makes a Rust macro less flexible than a Lisp macro in the context of this discussion? In particular, what do Rust macros tamp down on in terms of power that make them more justified for occasional use compared to a Lisp macro?

Lisp has a handful of language features that allow the definition of new syntactic abstractions: form level (DEFMACRO) and character level (SET-MACRO-CHARACTER). Just like it has operators to define new data structures (DEFSTRUCT and DEFCLASS). Just like it had operators to define new functions (DEFUN, DEFGENERIC, DEFMETHOD). Each of these defining forms materially change the way a programmer writes code. You don't need to add new syntax to change the language, and each kind of language change comes with its own tools and practices for working with them, debugging them, documenting them, and so on. All of this is to say: I don't see a good reason to have all of these remarks about syntactic abstraction when they very well could be made about data abstraction or control abstraction.

A useful language feature isn't something that needs to be maximized in idiomatic code. Syntactic abstraction is useful when it's useful, and when it is useful, it's usually extraordinarily useful—typically because a new syntactic abstraction allows a programmer to specify something much more directly or correctly than otherwise. (Other languages frequently resort to external processors or code generators to the same effect. Anybody who has used them knows how frustrating and difficult to debug they can be. But nonetheless, it's not that people do or don't want syntactic abstractions—they clearly
do—it's more a matter of how accessible we want to make it to the programmer.)

I did not suggest disallowing it anymore than I suggested we should disallow the definition of new classes in Java. Being judicious and deciding when it's worth it is key, and there are few general statements we can make about this without additional context.

Old-timers, at this point, but I take your point. I guess, for that matter, the terms "social engineering" (as it relates to manipulating people into divulging secrets, etc) and "doxxing" both came from the same community, too. How bizarre. Terms that were bandied about by kids in text files became actual industry jargon (and, in the case of "doxxing", arguably mainstream).

You’re very close to asking whether capitalism leads to the best quality of life, if you think of quality as going beyond the availability of products and services.

People who grew up in Soviet-era poverty of course see this differently than comfortable middle class people who feel alienated by soulless suburbia.

I think the article could be read as a way to reconcile the two.

For many purposes, we need anonymous authentication. I haven't heard about much innovation on that and similar privacy fronts in awhile.

Off the top of my head, a possible method is a proxy or two or three, each handling different components of authentication and without knowledge of the other components. They return a token with validity properties (such as duration, level of service). All the vendor (e.g., Polis) would know is the validity of the token.

I'm sure others have thought about it more ...
