>And it should be ended using the government.

I was surprised by two things when Chattanooga banned new short-term rental applications:

First) that it even passed

& 2nd) that the grandfathering clause conveys with the deed on all future sales [†]

But still I consider this a small and necessary victory to prevent future homebuilds from unhousing. A year later (last year) our surrounding county also placed its own bespoke STR restrictions, mostly different from the city's (of course!).

[†] IMHO, these have ALWAYS been a violation of most SFH zonings (e.g. R-1), so I would like to see some sort of "phase out" or "non-conveyance" so that eventually everybody is following laws enacted of its constituencies —if not immediate/timed

I really can't speak highly enough of Trino (though I used it as AWS Athena, and this was back when Trino was called Presto). It's impressive how well it took "ever growing pile of CSV/JSON/Excel/Parquet/whatever" and let you query it via SQL as-is without transforming it and putting it into some other system.

What an impressive feat of engineering.

> co-operate to achieve some common goal.

all systems are competitive, if the system involves humans - after all, even in a constrained environment like academia, where research is cooperative, the competition for recognition is still strong. This includes the order of the authorship presented in the paper.

What you're asking for, regarding cooperation to achieve common goals, is altruism. This does not exist in human nature.

As I said above, I did a lot of this when time and money constraints severely limited exploration of the solution space, yet I succeeded most of the time.

Guessing is a skill, and some people are better at it than others. An "educated guess" is based upon knowledge and experience, but little more.

I don't really know that this is what Kagi was looking for though. Perhaps they wanted something more than a guess but less than a full solution. Maybe just enough to gauge the confidence of the candidate.

The "new business" environment often involves a lot of guesswork.

Wow - there's free street parking in Lower Manhattan?! Yep, there's your problem!

Here in Sydney Australia, we don't have any congestion charge (there's been some talk about introducing one, but it's not really on the cards at this time). But it's pretty much impossible to find parking in the CBD (Mon-Fri 9-5) for less than around AUD$60 (USD$40) per day. There is literally no un-metered street parking anywhere in the CBD (also the parking inspectors are everywhere). Plus many of the routes in are tolled (although by no means all routes). Plus, things like the numerous one-way streets, bus-only lanes (with cameras), and ultra-low speed limits, makes it an extremely unpleasant driving experience (with a high risk of getting fines), for folks who are used to just driving in the suburbs. All of that effectively acts as a congestion charge - most people choose public transport over driving, when heading into the city centre, because in practice the cost of regularly doing the latter is prohibitive.

"King-crown=ruler" is IMO absolutely apt. Arguing that "crown" can be used metaphorically is a bit disingenuous because first, it's very rarely applied to non-monarchs, and is a very physical, concrete symbol of power that separates monarchs from other rulers.

"King-princess=man" can be thought to subtract the "royalty" part of "king"; "man" is just as good an answer as any else.

"King-queen=prince" I'd think of as subtracting "ruler" from "king", leaving a male non-ruling member of royalty. "gender-unspecified non-ruling royal" would be even better, but there's no word for that in English.

This is very speculative so I left it out of the blog post. But... 'market research' is typical endeavour for companies breaking into an unknown space, the decent ones will carry out focus groups with experienced professionals and pay for people's time.

This kind of "do something for X but we won't tell you how!" looks a whole lot like market research disguised as an interview, that way they can do the research for free.

This addiction and fear of things-going-bad-if-i-dont-listen-to-the-copilot is precisely why my workflow is a bit more simple and caveman-ish:

1. start a project with vague README (or take an existing one).

2. create makefile with the "prompt" action that looks something like (I might put it in a script to work around tabs etc):

```

prompt:

for f in `find ./ | grep '*.go *.ts *.files_i_care_about' | grep -v 'files to ignore' | pbcopy` do echo "// FILE: $f" cat $f done

```

3. Run `make prompt` to get a fresh new starting prompt, Go to Gemini (AI Studio) and use the prompt:

```You have the following files. Understand it and we will start building some features.

<Ctrl-v to paste the files copied above> ```

4. It thinks, understands and gives me the "I am ready" line.

5. To build feature X I simply prompt it with:

``` I want to build feature X. Understand it, plan it, and do not regenerate entire files. Just give me unix style diffs. ```

6. Iterate on what i like and dont (including refactors, etc)

7. Copy patches and apply locally

8. Repeat steps 5 - 7.

10. After about 300-400k tokens generated (say over 20-40 features) I snapshot with the prompt:

``` Great now is a great time to checkpoint. Generate a SUMMARY.md on a per folder basis of your understanding of the current state of the project along with a roadmap of next steps. ```

11. I save/update the SUMMARY.md and go to bed. When I come back I repeat from step 2 - and voila the SUMMARY.md generated before are included too.

I have generated about 20M tokens so far at a cost of 0. For me "copy/pasting" diffs is not a big deal. Getting clean code, having a nice custom workflow is more important. I am still ready to relinquish control fully to an agent. I just want a really good code search/auto-complete out of the LLM that adheres to *my* interfaces and constraints.

> Does anyone know of anywhere that managed to bootstrap good public transit after the fact?

Central Tokyo (inside Yamanote line) has almost no national railway lines (just one/two called Chuo between Shinjuku and Tokyo station). Most of its subways are inside central Tokyo. The second subway line didn't open until 1954. Tokyo is much later to build than London, Paris, or New York. I also think that Seoul started building trains very late.

I saw a video on Peachtree City several years ago and it really stuck in my head. Golf cart roads, like protected bike lanes, are really a “build it and they will come” project. The infrastructure has to reach a certain level of completeness before it will see mass adoption.

If I could take a golf cart on the roads safely, and there was a golf cart parking lot at a nearby rental car place for occasional longer trips, I’d give up my car in a heartbeat.

I guess it depends on what you mean by emotions. If you mean emotion as a state of consciousness then you would have to prove that consciousness is not an emergent property of matter and that CPU's don't have this property. Consciousness is hard to debate though since its pretty metaphysical in nature and there's no real argument against solipsism, so all argumentation starts with the axiom that all awake adult humans are conscious.

However, if you mean emotion as a stimuli, ie. a input to the brain net thats endogenous to the system(the human), then there's no question machines can achieve this, in fact the reasoning models already probably do this where different systems regulate each other.

Looks like London is on track to deploy similar technology. They did a trial in Croydon recently that was considered a huge success. From what I understand they actually ended up with pretty decent buy in from the locals as it had a noticeably positive effect on the community.

We'll probably eventually see it in more western cities as time progresses. Unsure what to make of it tbh.

Reading the paper further, there is this:

However, the BTB provides partial target addresses [28], so the attacker only needs to branch to an address where the lower portion matches the desired kernel target. The upper bits of the BTB target are provided by the victim branch source, which will be in the kernel address range. The technique follows the one we used in Section 6.1 and Figure 5.

So it seems to me that the actual difficulty from JS is less passing down the desired memory destinations (that's harder, yes, but I wonder if it's hard enough), but to generate (benign) branches to almost arbitrary addresses within the JS code, as it's probably neigh impossible to control for where those branches go.

Still, who really knows if there isn't some jump table generator or whatever to allow an attacker to generate branch targets arbitrarily enough (remember that it's not necessary to branch to the full address to train the branch predictor).

Because this would not be a vulnerability in any sense by itself. It would be yet another completely benign but unlucky piece of code that just allows the tire fire that Spectre is to be leveraged.

I'm probably missing other relevant aspects.

As for cache flushing, I think that's what the disclosure gadget does: "The disclosure gadget needs to use the two attacker-controlled registers to leak and transmit the secret via Flush+Reload", so that's also kernel code which we mispredict into. But I'm not totally sure.

> Sure it was striking given the position

That's the clue to the outrage. It was well known and enjoyed by the general public, and a pair of morons decided they were going to ruin it for everyone, for no clear reason.

> Compare far less outrage when a restaurant chain chopped down a 500 year old tree.

It's a crime, hopefully it gets prosecuted, but it wasn't as iconic.

I don't think there's a mystery here.

What you are saying sounds a lot like this:

It is interesting how google turned the tide on GenAI race, and seems to be leading the pack, with not only great fundamental research, but also interesting model and products. To what extent these remain a niche/nice to have or become a sensation remains to be seen, but I hope if they don't reach hype status, they might be released to the open weights world.

Ironically, I could’ve read all 50 pages of that RFC and still missed the actual issue. What really helped was RFC 1331[0], specifically the "Async-Control-Character-Map" section.

That said, I’m building a product - not a PPP driver - so the quicker I can fix the problem and move on, the better.

I live in Chicago and use a cargo ebike with a child seat for probably 90% of my trips. I can take my kid to school, go shopping, and go to my office on my bike, often quicker than if I were to take a car.

Chicago has (recently?) put a lot of focus on their bike infrastructure (protected bike lanes, bike signals, bike only paths, etc) and it seems pretty widely used.

>you p much repeated what i said. you want to be told how to use your phone. you'll use the apps that you're given to do the tasks they decide you can do on your phone. that's fine.

No, I have said entirely different thing.

Try to climb off you horse and maybe you will notice the difference between "apps you are given" and "apps I decided to use that are available on the market".

>but the person i was replying to was acting like android doesn't work

Well, that person was too emotional and given us almost no details. But to be honest the way Android behaves (unless you want to hack most of it) - it can be described as "doesn't work" from iOS user's perspective. And no, not because of "walled garden" or some other bs you imagine. Most of the time android phones (yes, even top models) simply lag (or start lagging over the time). Not to mention that the base line quality of software is simply lower than on iOS.

>they were showing clear bias.

And so are you. You are doing _exactly_ the same when writting things like "walled-garden" and "you want to be told"

> The sentence “What if I told you that analog photographers captured HDR as far back as 1857?” is explicitly claiming that analog photographers use “HDR” capture,

No, it isn't. It's saying they captured HDR scenes.

> The result of the juxtaposition is that the article did in fact claim Adams used HDR

You can't "use" HDR. It's an adjective, not a noun.

> Film’s 12 stops is not really “high” range by HDR standards, and a little exposure latitude isn’t where “HDR” came from.

The Reinhard tone mapper, a benchmark that regularly appears in research papers, specifically cites Ansel Adams as inspiration.

"A classic photographic task is the mapping of the potentially high dynamic range of real world luminances to the low dynamic range of the photographic print."

https://www-old.cs.utah.edu/docs/techreports/2002/pdf/UUCS-0...

> Perhaps it’s useful to reflect on the fact that HDR has a counterpart called LDR that’s referring to 8 bits/channel RGB.

8-bits per channel does not describe dynamic range. If I attach an HLG transfer function on an 8-bit signal, I have HDR. Furthermore, assuming you actually meant 8-bit sRGB, nobody calls that "LDR." It's SDR.

> Analog cameras have exposure control and thus can capture any range you want.

This sentence makes no sense.

Yeah but back then streets were for people and horses. There were no clear markings separating the sections, there were no laws making it illegal for you to walk on the streets.

If there were traffic laws, nobody knew them and people wouldn't know which way to go to avoid a head on collision.

If you'd just replace cars with horses today it would go a lot different.

Hey HN,

I’ve spent the past three years building a mathematical framework called EchoKey. It started as an attempt to express patterns I’ve seen in the world—often dismissed as noise—and evolved into a formal system grounded in recursion, synergy, outlier dynamics, and fractality.

EchoKey is fully open-source and released under a permissive license. It’s built to analyze, control, and predict the behavior of high-dimensional, nonlinear, and emergent systems. It blends ideas from quantum mechanics, chaos theory, and systems engineering into a single operational framework.

Here’s what’s included:

1. Encryption System An entropy-rich, synergy-enhanced encryption tool with keystream scrambling, multidimensional flip maps, and Numba-accelerated batch processing.

2. Quantum-Classical Sequencer A hybrid system using LSTM and Random Forests, quantum base-10 encoding, and synergy-informed refraction to extend fractal sequences.

3. Quantum Gravity Simulation Models forward and reverse transitions between quantum and classical states using real solar TOV metric data, synergy matrices, and fractal potential coupling.

The full math is published in a formal LaTeX preprint, and the code + simulations are available here: https://github.com/JGPTech/EchoKey

If you're into systems theory, quantum computing, or new mathematical languages, I’d love your thoughts. Ask me anything — math, physics, code, life, ethics.

— Jon

I'm not sure if it's "a lot", or more than the general population. I think last time I checked about 40% of the US population still approved of Trump... :-/

But yeah, there's definitely a streak of that, and it also seems people are more bold/outspoken in ways that I didn't see before. Not long ago I saw someone argue that some children TV show was woke garbage because ... it featured mixed race couple. What the actual fuck? "Hi, I'm from the KKK, and I'm wondering if you have time for a chat about the darkies and Jews?"

When that Google AI was doing crazy stuff such as displaying black Nazi soldiers, the Musk crowd was all over it (and according to many, the only possible answer was that it's a woke soyboi beta cuck brainwash attempt). But God forbid Musk does anything wrong... then it's "no politics on HN".

Anthropic found that it Claude will pretend that it used the "standard" way to do addition- add the digits, carry the 1, etc- but the pattern of activations showed it using a completely different algorithm. So these things can role play as introspecting- they come up with plausible post-hoc explanations for their output- but they are still just pretending, so they will get it wrong.

So you can teach a model to sometimes ask for clarification, but will it actually have insight into when it really needs it, or will it just interject for clarification more or less at random? These models have really awful insight into their own capabilities, ChatGPT eg insists to me that it can read braille, and then cheerfully generates a pure hallucination.

I was sketching a sci-fi book idea in a similar tone with the following tones:

- what if AI took over

- what if the laws and legalities that allowed AI to take over bloodlessly just through an economic win force them to have a human representative to take legally binding actions in our society

- what if there developed a spectrum of individuality and cluster for different ai entities leading into a formation of processing guilds with AI agents. Limiting themselves in their individual time to a factor 10 Human Processing Speed for easier Human / AI interaction and to enable one to share the perception of their human representative without overloading them

You can certainly convince them to ask for details, but I'm not sure whether that makes them any good at knowing when exactly to ask vs just asking some percentage of the time regardless.

That is, does it actually know when it doesn't know, or are you just making it less confident overall, so it asks questions with no actual insight? Convincing a model to roleplay as someone who doesn't know things vs teaching a model to have insight into when it does and doesn't need clarification seems like a tough one.

1. I’m not trying to convince you or anyone. In fact people always convince themselves, you only can share facts and opinion with them and they do their own arbitrage. Eat what you want to eat.

2. Speak for yourself. "People like me" doesn’t mean much, you may share some thought but everyone have a whole life of different experiences. Your argument on price and affordability makes sense may be shared by others but is probably more complex and nuanced than only that sentence, and others sharing that thought with you today may have a slightly different one yesterday and tomorrow.

3. Not many admit it, but people do changes opinion sometime, framing it as a logical conclusion to thinks they discover, read etc… nobody wakes up and become vegan out of nowhere. They had experiences, process it and make they own arbitrage just like you’re doing. In that sense I know my message has been read by more that only you and hope it helps understanding that many vegans eat more that impossible-burger only.

4. Genuine questions : why do you eat meat ? I guess it’s more than the affordability only. otherwise you’ll smoke, fentanyl yourself and drink only sodas if you can. When I have long talk with someone it usually comes down to habits or tradition. I’d be happy to read your opinion on that question.

“some apps have a core use case that requires broad access to files on a device, but can't access them efficiently using the privacy-friendly storage best practices. Android provides a special app access called all-files access for these situations.”

“For example… anti-virus apps… file manager apps, backup and restore apps, and document management apps“

https://developer.android.com/training/data-storage/manage-a...

NextCloud provides backup, restore, and document management.

I guess you may know more about this than the official android docs, but maybe you are just being blinkered by some incorrect assumption?

Maybe we would be best to frame this another way. What permissions do NextCloud need to be able to replicate “Google One”? The complete replacement of Google drive (the service, not the app - you are consistently conflating the two) is what they aim to be. Is that something that can be done with SAF, or are Google using elevated permissions to lock competitors out?

> It happens to literally every existence of life across the universe because the final emergent property of energy gradients 100% leads to pure logic machines.

This sentence has way too many assumptions doing the heavy lifting.

“Pure logic machines” is not a thing because literally, there are things that are uncomputable (both in the sense of Turing machine’s uncomputability, and in the sense that some functions are out of scope for a finite being to compute, think of Busy Beaver)

To put it the other way, your assumption is that machines (as we commonly uses the term, rather than scifi Terminator”) are more energy efficient than human in understanding the universe. We do not have any evidence nor priori for that assumption.

How about from low-income commuters?
