Love your project. And the mentiond metrics ΔS (semantic tension), λ_observe (viewpoint drift), and E_resonance (contextual energy) totally align with my mental model.

Also loved your phrase: "kind of like how meaning resists compression when you flatten it too early." That's a key point. Implicit in that is the assumption that flattening will eventually happen — and I agree (assumed for efficience in last term): Just like how we create flat maps of the Earth sometimes a flat projection is useful _as long as_ we understand the properties of the deformation and the underlying surface. If we don't, EEUU might seem a lot bigger than it's "represented", in our euclidean view.

That interpretation really clicks for me.

I'm currently exploring *geodesic-aware training methods for IR*, based on contrastive / triplet loss. Take a look if you're curious: [https://github.com/Intrinsical-AI/geometric-aware-retrieval-...](https://github.com/Intrinsical-AI/geometric-aware-retrieval-...)

Still recent and (very) experimental — but already done some initial tests. The goal is to construct a differentiable graph over the embedding space and propagate training signals end-to-end. Lots of work ahead, but preliminary results are promising (and adjusting things with o3 feedback ofc).

Are you open to collaborating or jamming on this? Would love to sync up — are you on Discord or Slack?

Thanks again for pushing this forward.

What I’ve observed from six years of informed delivery is that the sorting step that generates the images for informed delivery happens before the step that handles forwarding and return to sender.

I’m not sure that any of the cases are that big of a privacy breach: It’s more inline with either getting the neighbor’s mail in your mailbox (which in my experience happens at about the same rate) or getting previous residents‘ mail in your mailbox (although my current carrier, after checking with me, intercepts most of these on her own initiative so I don‘t have to deal with them).

i started my comment with a double-quote indicating that the content is directly from the article starting right at the beginning of the introduction section (to your point about starting at the beginning).

i went down to Euler’s sums of two squares identity which i think demonstrates clearly that even middle school algebra suffices to get a sense of depth from this work showing that a product can also be seen as a sum in a more sophisticated context (ie beyond arithmetic structure emerges).

i fail to understand your disapproval on my providing additional context from the page to indicate that this is likely a more interesting post to a wider set of readers than most might assume just from the title. i didn’t feel the need to editorialize further because i thought the quote says it all on its own.

The single most irritating killed feature from Apple. Redesign half of their UI to rely on 3D Touch to make sense, then get rid of 3D Touch without redesigning the UI. Previewing links, moving the cursor, interacting with items, they’re all “press and hold until haptic feedback” instead of “quickly press hard and get immediate feedback.” Easier to accidentally trigger, slower to trigger on purpose.

I think there are more fundamental questions needing to be answered:

- What does it mean to be human?

- Can an AGI be considered human? We need to answer the previous question in order to answer this question.

- Will the human race have gone extinct if an AGI arises that embodies human values and is considered human?

- Finally, assuming such a "human" AGI were to arise, would its legacy then also be the legacy of the human race?

Maybe all of history was building to this point. Different religions have discussed this for thousands of years - man breaking out of the confines of his body. How do we know that AGI isn't the way to achieve that? I can tell you one thing, I can conceive of an AGI exploring the galaxy. Meanwhile it's hard to imagine humans exploring the solar system. I think we're going to reach the conclusion that physics and biology prohibitively confine us - confines that don't exist for AGI.

Chickens learn from their mothers how to scrounge for food when they grow up free range. Releasing 1000s of tiny yellow chicks into the wild with no mother is way more cruel than current practises I reckon.

I reckon the chicken industry also generates way more male chickens than what a park can reasonably handle. People eat lots of chickens.

> This is likely far from over: Collective Shout is no doubt feeling emboldened by a second public success in its efforts to police content on Steam specifically. The games I saw removed from Steam in this wave all featured risible content and suspect quality, but Collective Shout has a broader anti-pornography, even anti-expression remit that it has demonstrated in the past.

Yes indeed, a huge success like this will give them a big boost in motivation and funding for many, many years to come. IMHO we need to regulate away the credit card processing companies ability to discriminate like this, and while we're at it we should stop letting them heavily tax the entire economy

> That's not a clarification of what you are referring to, that is just stating

You're right, that was a conclusion. And the context was clear from my original post.

To be precise, when I describe that ideology, the concrete example I have in mind is the kind of burdensome framework detailed in the RCSR. My conclusion about that framework is that it ignores reality and causes harm, despite its intentions. and 'Tough news' is the evidence for that specific conclusion.

> At worst McDonald's was probably like 10% responsible

80%, according to the jury.

> The jury actually did find the woman was partially responsible

Correct, which was factored into the award of actual damages, reducing the $200,000 in damages to a $160,000 award, since it was in a comparative negligence jurisdiction.

> it was the judge that decided on the absurd damages amount. It later got reduced and settled out of court

No, it was the jury that returned the original $2.7 million punitive damage award, which the judge reduced to $480,000, for a total actual+punitive award of $640k in the trial judgement.

The parties did settle out of court while an appeal of the trial judgement was pending.

To be clear here, I'm not arguing that OpenSearch/ElasticSearch is an adequate substitute for Postgres. They're different databases, each with different strengths and weaknesses. If you need JOINs and ACID compliance, you should use Postgres. And if you need distributed search, you should use OpenSearch/ElasticSearch.

Unless they're building for single-host scale, you're not going to get JOINs for free. Lucene (the engine upon which ES/OS is based) already has JOIN capability. But it's not used in ES/OS because the performance of JOINs is absolutely abysmal in distributed databases.

Yeah I think my original comment was too cynical and misplaced when lumping in all of the Strong Towns organization with Not Just Bikes style content. I’ll read through what they have today.

Admittedly my experience might be colored by the fact that they don’t seem to have much of a presence in my home town of Boston - it’s more other groups like the Cyclist Union showing up at meetings carrying forward things like bike lane advocacy, etc.

The key factor in deciding if it’s reaganomics or economics is: do people actually pass it on.

Reagonomics doesn’t work because the rich hoard wealth, use leveraged money to keep their hoard rather than it trickling down, and use their hoard to influence policy and the social environment against the working class.

Electronics also don’t trickle down when you toss your old phone in a drawer rather than passing it on. Or when software updates make it unusable after 3 years. Or when parts (battery, screen glass) aren’t replaceable. Or when social cache is attached to new electronics but not older ones.

So the existence of high end audio products that CAN trickle down doesn’t mean they ARE trickling down.

It's definitely no "let's just do it over the weekend" job, but otoh, you don't have to do it all at once, nobody uses every tool. You'd probably need to still roll out by unit or at least in waves (e.g. for the unit that handles building permits, which is much less complex).

I do agree that there's no good incentive. The other reason I've learned is their organizational issues: heavy focus on certifications, much lower salary vs private industry, heavy on the bureaucracy and office politics, and a lot of dead weight. That doesn't get you skilled people with plenty of motivation, and you get the outcome you'd expect.

The politicians might not know tech, but the NSA, GHCQ, etc. that push for these anti-encryption laws most definitely do know technology, and is the main lobby against encryption.

It goes beyond just getting politicians that understand tech. We need politicians willing to rein in the intelligence apparatus put in safeguards, and checks and balances on their power.

Increases in Dallas and Los Angeles are about average over the decade. (National average is 93.9%)

https://fred.stlouisfed.org/series/CSUSHPINSA

Here is another interesting chart:

https://fred.stlouisfed.org/graph/?id=CSUSHPINSA,SFXRNSA,LXX...,

Which place seems more expensive since 2000? Can you see the big drop in 2025?

I think the story of Atlanta and Dallas is a story of cheap housing being available for a long time until it started to get used up. In Atlanta, it's not just exurban development, a lot of in-city neighborhoods had some growing ability. But the mixture of people relocating to Atlanta and the constraints of a car-based city with difficult zoning have basically stopped new supply. Small single-family houses get replaced with larger single-family houses and the missing middle is harder to find.

Yeah, we did do some games, though nothing crazy - we did breakout and asteroids if I remember - not exactly groundbreaking.

The interesting thing about it was that we had very little RAM but the FPGA was quite fast, meaning instead of a framebuffer we scanned out tiles and sprites to the scanline at realtime, at a relatively high resolution (1024x768).

This combined with the low color depth (the 'DAC' was a resistor ladder per color channel, giving us 2 bits per channel, or 6 bits in total), meant we had that dithered, Transport Tycoon-y look, with tilemaps and animaton, so it looked quite okay by the standards of 2d games.

Yep, ~1kW as mentioned. Depending on your electrical rate, break even might be years down the line. And obviously the Mac Studios would perform substantially better.

Edit: And also, to get even half as much memory, you need to spend $10k. If you want to host actually-large LLMs (not quantized/distilled versions), you'll need to spend close to that much. Maybe you can get away with 256GB for now, but that won't even host full Deepseek now (and I don't know if 512GB either, with OS/etc overhead, and a large context window).

True if you look at the cost to build the plant, but it’s hard to colocate enough solar with heavy users, land near there is expensive, and transmission capacity is pretty hard to get built, so something very power dense with a small footprint is helpful. I haven’t dug into the numbers, so I could very well be wrong that it pencils out when you consider those.

And there are efforts to make building out transmission and interconnecting with the grid more streamlined, so maybe some of those problems will be gone by the time fusion’s ready.

Someone said recently that it’s nicer to have bad laws and good tech than a bad tech and good laws, solar+storage seems like it’s in the former now, and if we can clear the bureaucratic hurdles, we’ll see it boom here like we’ve seen elsewhere.

You are still completely ignoring my point.

You, presumably, are not new to Linux. You know how to fix your system. The users CachyOS is targeting do not. They will run into walls, get frustrated and leave.

I really couldn't care less that someone like you uses some Arch derivative, because they don't want to spend the 3 hours doing the setup themselves.

Just FYI,the Arch setup is as easy as setting up e.g. Debian, unless you are terminally afraid of using terminal UIs.
Show HN: SuperOptiX – Evaluate, Optimize, Orchestrate DSPy AI Agents – BDD Style
by Shashikant86 | 2025-07-21 16:53:56+00:00
I posted about SuperOptiX previously, but at that time the website and documentation weren't fully polished — we were still finalizing core components. Since then, we've fully revamped the site, completed detailed developer docs, and rolled out all major features.

What’s SuperOptiX? It’s a full-stack Agentic AI framework built for real-world, production-grade agents with a focus on: Evaluate-first development (BDD/TDD style specs like Cucumber or RSpec way) Optimization-core architecture (powered by DSPy) Multi-agent orchestration (think Kubernetes for agents) Context Engineering, Model Management, Memory Routing Declarative agent specification with SuperSpec (Think RSpec for Agent Engineering)

Ideal for teams moving from agent demos to scalable, maintainable systems.

Website: https://superoptix.ai Docs: https://superagenticai.github.io/superoptix-ai/

Would love your feedback from HN Community — we’ve put our soul into getting this right for agent developers and infra engineers. Happy to answer questions!

That is a fair point, but if you can't even bother why would you give any advice then?

That's why I went out of my way to try my hand at marketing something for the first time, but the only kind of advice I've got is a little bit depressing.

No, my parents and in-laws have routinely expressed how much they love to watch and spend time with my kid. But they're also retired and have lots of trips and hobbies going on. They're getting older and aren't as physically able as I am in regards to picking up and chasing after a highly mobile toddler. My husband and I aren't their only kids either. They also spend time helping out our siblings.

So it's really more of a me thing why I don't ask them to take care of him "full time". If I really needed them to, they would (and happily).

If I were a VC or PE firm, this is exactly where I’d be putting a lot of money in the next year or two. Right now there’s a lot of fear given the stance of the current administration, which makes it pretty ripe for smart money willing to play the long game (as Buffett famously noted).

The technology keeps improving, clean energy is increasingly shaping up to be a new arms race with China, and politics these days tend to swing back and forth wildly. By 2028+, it’s very plausible we’ll see things 180 and there'll be plenty of government attention given to clean energy. Even the current administration could change their tune if it's positioned as "beating China" (or even for no reason at all, because who knows with them).

Spending a couple years to prop it up and become a well-established player by then could be a huge advantage.

ALICE has done good work here[0] in calculating a realistic inflation rate, and it contrasts quite a bit from the official CPI. I've also read that the 1990s changes to the CPI drastically cut the official inflation rate by excluding more things from the calculation. If that had not happened, inflation would have tracked more realistically to the average person in the US

Indeed, there are regional sorting centers that then send to the local post offices to go to the carriers. Although what I find odd is that for residential delivery, I always get the mail the same day, only at my P.O. Box does the mail sometimes come 1–3 days later.

If you look at the email, the promise isn’t “coming today” but “coming soon”.

No, memoization is not caching. That’s a reductive understanding that causes no end of trouble.

Caching is global shared state. It brings nearly every problem that global shared state brings with it. If you conflate the two you miss all of the advantages of DP and “just use caches”.

Memoization in the scope of DP (some languages misuse the word in their APIs) is acknowledging that a problem is self recursive and eliminating the duplicate work by either inverting the problem or storing previously calculated values. These are usually call graph scoped. Nobody else sees the value. For instance in the case of solving Fibonacci with iteration, you need only remember the previous two values, which you store in registers. There is no table. There is no O(n) storage space.

Again, tabulation is when the contrast becomes stark. You’re creating an array where the relationship between the values contains information that makes the calculations cheap.

I don’t think this tracks for me. Sure urbanist YouTube doesn’t really talk about local politics, but an extremely high percentage of people interested in city planning that I know have started doing something to influence local policy. One of my coworkers ran for city council recently. It turns out that people who are interested in watching multiple hour videos on the specific widths of roads are also not that bored by the ins and outs of local politics.

>it seems that the answer to whether or not a general model could perform such a feat is that the models were trained specifically on IMO problems, which is what a number of folks expected.

Not sure thats exactly what that means. Its already likely the case that these models contained IMO problems and solutions from pretraining. It's possible this means they were present in the system prompt or something similar.

Good stuff. You could get much better bandwidth than this by tokenizing and using something like a Huffman or arithmetic code on token frequencies. As a simple example, if you set your tokens to be all English words - let's say there are between 500k and 1 million - that's about 9-10 bits per word. I am sure you could do much better than this as well
by mezentius | 2025-07-21 16:56:33+00:00
The exact number “24” may be a standard for historical reasons, but a frame rate AROUND 24 is not an arbitrary standard. Higher frame rates require more light so that the image is properly exposed for the 1/(2x frame rate) of a second (assuming a 180-degree shutter angle) that the shutter is open. Doubling the frame rate requires doubling the amount of incident light, so going to 120 fps from 24 requires ~5x more light for a given ISO rating and aperture.

If you think about how light falls off in proportion to the square of its distance from the source—and that generally actors don’t stand in one place, but move through large spaces where they must appear to be lit evenly—you start to see that this is not just a question of “efficient LED lighting.” Shooting at high frame rates requires an enormous amount of light that cannot easily (read: cheaply, quickly, without higher expenses) be brought to bear in a normal production outside of controlled studio conditions.

> being in public with no intention to be filmed

This isn't a possible situation, and people would do well to internalize that. If someone said "being in public with no intention to be seen", it would be clear that it's unreasonable -- asking everyone to pretend you're invisible -- but change it to "seen and remembered with high fidelity" and people want to roll back to before constantly-filming cameras were common.

If you're in public, people may see you. If people can see you, they may preserve a memory of seeing you, internally or externally to their head.

This is very interesting, I've been increasingly frustrated with Daikin's approach to mobile control and the incredibly poor execution of the original wifi module/automation:

- the wifi module and temperature sensor are right next to each other, which was causing the unit to read temperature 2-3 celcius higher than actual due to wifi sensor heat (measured by another temperature sensor on the other side of the unit). This was fixed in a software update, but seems like poor design

- it looks like the original wifi module uses a lot of power, at least according to the app readings. Didn't verify this one, but it tracks with how much it heats up even if the unit is completely off

- no way to connect an external temperature sensor, so even with a software fix to the temperature sensor reading, my room is consistently 2-3 degree celcius colder than the set temperature

- there are no release notes for the official firmware updates so you never know what can break if you update (but an update did fix the wifi module heating issue)

- the (new) app had power usage data for the past couple of years. Now they decided to only store a year? Or maybe just deleted the old data. Either way, now it's lost without any notice or way to archive it

---

That said, how likely is it that Faikin causes a hardware failure in an indoor or outdoor unit in case of a software bug? I'll definitely try it but I'm a bit uneasy with an open source software designed for what seems like a massive range of devices, and no way for the maintainers to accurately test against each one

> Still, the viral potential of these kinds of stories is a warning sign that our culture is obsessed with shame, surveillance, and control. An obsession with other people’s private lives is a sickness.

I think (generally speaking) on the internet this is highly exacerbated by the dehumanization of others. For whatever reason, when we aren't face to face, we tend to not connect to the humanness of the people on the other end. This is easily observed when people get into cars and "observe" but don't connect with humans in the other cars who sometimes make suboptimal driving decisions that infringe on sensibilities ("that asshole cut me off! I'll drive recklessly around him to show him how angry I am"). Getting on the internet seems to make this even worse.
