The details got worse too.. the Medium author is arguing that Propublica is mistaken when they call the tool inherently biased because you can group the recidivism rates such that the AA rate is ~close to the claimed one but then they admit;

> One point about the ProPublica criticism did appear correct. Caucasians and Hispanics are predicted to recommit crimes at a substantially lower rate than they actually do.

> For Caucasians, they are predicted to recommit 25% of the time, but they actually recommit 39% of the time. And the prediction accuracy for both groups are substantially lower than for African Americans.

So the software isn't biased because if you use a different measure it ~accurately predicts recidivism for AA folks and dramatically underestimates how often Caucasian convicts reoffend? what?

I'm not an academic economist, so what do I know, but I think the authors aare missing something else.

I think the productivity was in some part driven by minimum wage laws. At lower wages, developing, installing and maintaining ordering kiosks and smart phone ordering apps makes less sense, because fast food cashiers are so cheap. When fast food cashiers become more expensive (and the technology costs come down) kiosks and apps make more sense. The same amount of food sold without the cost of cashiers is the resultant increase in productivity.

So my theory in a nutshell was that cashiers added little value. Substituting capital for labor led to labor productivity gains.
Sure. And all outputs should be public domain and the service should be free.
It doesn't, in the early 90s I was even younger in the US and I had to walk to school about a mile along a busy street. There was no other way for me to get there, no bus or anyone around to drive me.
100% agree with the title.

I live ~1 mile from the local school complex (primary, middle, high all share a gigantic piece of land, though are separate full-size schools). You literally don't have to cross a street to get there from my house - it's all neighborhood walking paths and there's a short underpass at the one road. Yet, kids are not supposed to walk. There's a bus, which isn't the end of the world. Except in the time it takes to wait for the bus, you could walk most of the way to school. And 1/4 of the parents drive their kids anyway.

It's completely absurd.

Of course, I walk the ~1 mile to my office in the other direction and most of my coworkers think I'm a loon. So, I guess this shouldn't be surprising. Americans are just hard-wired to drive even the shortest distances. We've done such a piss-poor job with urban planning and transit design that 3+ generations of Americans think anything but a car is unthinkable (literally, I don't think it crosses their minds).

> Suppose you have 100 functions that each need 100 bytes of scratch space. Statically allocating everything like you describe means you need 10KB of memory reserved. But suppose there is one main function, and the rest are helper functions, and the main function calls each helper function one at time and the helper functions don't call anything. With the static approach, you still need 10KB. With the stack-based approach, you only need 200 bytes (the stack space for the main function, and the stack space for the helper function it is currently calling).

This is not necessarily the case: if you statically analyze the call graph, you may be able to prove that two functions will never be live at the same time, and thus reuse memory regions for their local variables: https://github.com/llvm-mos/llvm-mos/blob/main/llvm/lib/Targ...

Of course, recursion, function pointers, and dynamic linking will defeat (or at least complicate) this scheme.
This is a somewhat nihilistic take with an optimistic ending. I believe humans will never fix hallucinations. Amount of totally or partially untrue statements people make is significant.

If the comment reflects the culture of the people sitting and eating at the bar, a preference to forgo sitting and eating at the bar seems quite rational to me.

I'm not a regular/local. Why would I go where I am not welcome?

If I owned the restaurant, why would I cater to an unwelcoming crowd?
Agreed. We don’t have much of a car line since it’s a walk-to-school neighborhood (90% walk). Still, k-2 are dismissed to parents. Once 3rd grade hits it’s open.

Seems like a fine balance to me.
> deny your natural emotions.

That is the opposite of Stoic practice. I have never heard Stoics denying things. What does it mean to deny things that happen? Emotions are not in one's control. Whenever they come up, one would observe and act according to Stoic virtues. If one has failed to observe, then they reflect on the failure and intend to observe in the future.

Uncle Bob tried and failed to use his own strategy of many small functions to solve sudoku. There’s been a lot of Trough of Disillusionment talk about him lately. My impression of him is that he’s got the right code organization idea but for the wrong reasons, and so his ends often don’t justify his means. It’s a common pattern in software to guess the wrong reasons why something works, and then overfitting to the wrong reasons.

Cassowary's big differentiator 25+ years ago was that it is robust against cycles in constraints and supported inequalities. Those two facts made it instantly way easier to use than the local-propagation-based solvers that predated it (think spreadsheet-style formulas referencing cells where you can only compute values using equality assignment and you can't create cyclic references).

Cassowary being able to solve that broader class of problems in an efficient and incrementally (using prior solutions to the problem to make subsequent solutions even faster) was why Apple chose it for Autolayout in the later '00s. Their Visual Formatting Language was a nice ease-of-use enhancement, too.

I've never understood this critique. Models have the capability to say: "oh, I made a mistake here, let me change this" and that solves the issue, right?

Our child was being bullied on the bus by kids twice their age because there was no one other than the driver to monitor. I will not subject a kindergartner to that.

One time the bus arrived a full hour late and the people we could call to ask where it was had already went home. I was considering calling the police. Turns out the bus was late because they didn't have enough busses and it had to complete a different route first.

I hate this idea that software "rots" all by itself when it's just left on a device and is impossible to keep working. I would at the very, very least expect my device to work exactly as it did on day one, for the next 50 years, assuming I don't change the software. It's bits on a flash drive! It doesn't rot, outside some freak cosmic ray from space flipping a bit.

If you're saying the software stops working because the backend it talks to goes away, well that's a deliberate choice the company is making. All they have to do is have a proper versioning system and do not touch the backend service, and it also should work forever.

> Yet, kids are not supposed to walk.

According to who?

Reading these comments reminds me that America is a big place and experiences are very different from one location to the next. My closest school has hundreds of kids walking to and from through all the neighborhoods if you drive by during morning or afternoon hours.

My last in-office job had numerous people with 20-40 minute walks as part of their commute (except in rain/winter). We had people who routinely biked 10+ miles to the office.

It's not "Americans are lazy". It's the people you're around.

Abstract: "We document that, after remaining almost constant for almost 30 years, real labor productivity at U.S. restaurants surged over 15% during the COVID pandemic. This surge has persisted even as many conditions have returned to pre-pandemic levels. Using mobile phone data tracking visits and spending at more than 100,000 individual limited service restaurants across the country, we explore the potential sources of the surge. It cannot be explained by economies of scale, expanding market power, or a direct result of COVID-sourced demand fluctuations. The restaurants’ productivity growth rates are strongly correlated, however, with reductions in the amount of time their customers spend in the establishments, particularly with a rising share of customers spending 10 minutes or less. The frequency of such ‘take-out’ customers rose considerably during COVID, even at fast food restaurants, and never went back down. The magnitude of the restaurant-level relationship between productivity and customer dwell time, if applied to the aggregate decrease in dwell time, can explain almost all of the aggregate productivity increase in our sample."

Huh. Interesting!

The finding is consistent with both the changes, since the pandemic, in my own eating-out habits and the behavior of other customers I see at restaurants I visit regularly.

Nonetheless, seeing it validated with an analysis of largish-scale data is worth the read.

The question is whether eating-out habits have permanently changed, or whether they will eventually revert to pre-pandemic patterns.

Thank you for sharing this on HN!
Yeah, I think a lot of people talk about "fixing hallucinations" as the end goal, rather than "LLMs providing value", which misses the forest for the trees; it's obviously already true that we don't need totally hallucination-free output to get value from these models.

A failsafe firmware reset back to a safe and secure state yes. The factory state is not necessarily that, so no.

> For the first 15 years, OpenSSL membership was mostly a small collection of individuals working on a part time basis and the membership fluctuated and changed through those years.

I never claimed OpenSSL was the product of a lone wolf or that teams have no place in coding. The essence of my point is that the invocation of "teamwork", often as a concept and practice distinct from the sum of its parts, obscures the significance of individual contributors who making great software. After all, code is a mirror of the mind. That one can distinguish between great and not-so-great code implies that one can distinguish between a great and not-so-great coder.
If I can speculate: your perspective seems to be at least a second, maybe third-order perspective, of someone in an atypical environment surrounded by would-be stoics, who are all participating in order to succeed in e.g. middle management. This corporate stoicism produces suboptimal product results because while stoicism is perhaps necessary and valuable to hold a position, as you noted it is fundamentally detached and dishonest.

But until someone lives in your version of the social environment, they cannot see the relative value of a return to “radical candor” and so you get rejections, both from people behind you in their profession into stoic corporatism and from those who make their living from behaving in accord with it and believe they are superior for it.
Yup, they pretty much state that explicitly right in the abstract. I think we have a relatively rare example of a clickbait scientific paper title, here!

“If everyone’s doing takeout, you need fewer employees” isn’t exactly a shocking revelation.
I would have guessed that the surge had something to do with faster payments, namely contactless and the wireless terminals. In a way, it's even broader than that: if you order for pick up and prepay, payment is pretty much out of the picture entirely, replaced by just verifying that you are getting the right order. Then you're avoiding the productivity losses in serving the dishes, washing the plates, etc.
Gotcha, so then you agree that there is exactly zero cases or evidence of anyone ever being punished for this, which is the most important part.

If you do this, you are not going to be held legally liable for anything.

I just want to point out a few things:

You have made four "show HN" submissions in the past four days. Two of them are the same repo. One stimulated quite a lot of discussion and criticism, which you didn't really acknowledge or address, e.g. https://news.ycombinator.com/context?id=43335277 You spent far more time in that thread sharing what sounds like advertising and marketing-speak regarding your "blazingly fast" tool and the "interesting" origins of the tool's name.

Some of your comments also sound LLM-generated. At least one of the repo READMEs do, too. And the project you shared today relates, indeed, to a tool that turns GitHub repos into prompts.

As far as I'm aware, you're not breaking any actual HN rules, but you could do a much better job of upholding some basic rules of etiquette and acknowledge the time and effort people are spending reading your code, discussing it, and offering feedback.

Edit: I take back my claims that you're not breaking any actual HN rules:

> Please don't use HN primarily for promotion. It's ok to post your own stuff part of the time, but the primary use of the site should be for curiosity.

And yet less 40% of students who live within a mile of school walk regularly. For kids who live <.25 miles, that number is still <50%. Walking a quarter of a mile takes ~5 minutes, maybe a bit longer for a small kid with a large school pack.

Many should be able to walk almost as fast as loading up the car, waiting in the queue, etc.
> Do we, though?

Yes we do, and it's covered in the article.

It's not kidnappers. It's distance to school.

80% of kids live too far to walk. It's not that their parents are afraid of kidnappers, it's that they literally cannot feasibly walk to and from school every day.

Built a Weather Assistant Using Snowflake, Streamlit, and Claude
I've created a conversational weather assistant that leverages Snowflake Cortex's AI capabilities with Claude 3.5 Sonnet.
The application allows users to ask natural questions like "Is it going to rain in Seattle today?" or "Should I wear a jacket in Chicago?" Claude handles calling the right APIs, parsing responses, and providing straight answers without requiring users to decipher weather jargon.
Key features:

Leverages Claude 3.5 Sonnet's tool use capabilities
Integrates external APIs securely within Snowflake
Creates natural conversation flow between user, AI, and data
Runs entirely in Snowflake - no additional infrastructure needed

The most interesting aspect is watching Claude determine whether to use the weather tool based on the question context.
This implementation just scratches the surface of what's possible with Snowflake Cortex AI and Claude. Consider the possibilities of adding tools for travel recommendations, financial data lookups, or inventory checks.
