All of logic and math is a convincence tool. There are no, circles, quantities. Reality just is. We created these tools because they're a convinent way to cope with complexity of reality. There are no "objects" in a sense that chair is just atoms arranged chair-like. And atoms are just smaller particles arranged atom-like and yet physics operate in these objects treating them as something that exist.

So, now we have created these mental tools called mathematics that are heavily constrained. Then we create models that are approximately map 1:1 to some patterns that exist in reality (IE patterns that are roughly local so that we can call them objects). Due to the fact that our mental tools have heavy constrains and that we iteratively adjust these models to fit reality at focal points, we can approximately predict reality, because we already mapped the constrains into the model. But we shouldn't mistake model for the reality. Map is not territory.

In most countries it's 80% if your household salary is such to support it + household expenses, and approaching 0% if it's not.

And it's intense just for the first few youngest years, when the ratio of daycare employee : baby is 1:2 to 1:4. That doesn't last more than a few years, in which most parents/grandparents want to spend a lot of time with the baby anyway, and less at work.

But from age 4-18 school takes care of the vast majority of daycare hours while you're at work. Even after-school programs become cheap, a group of fifteen 12 year olds can be managed by one daycare employee.

Europe's fifteen minute cities also help, I was going home from school/activities by myself from a young age, because the whole town is walkable/bikeable easily and safely.

I'm taking a very crude approach for now. My "improvement agent" has a few distinct stages: A goals extraction step that explores the repository, with some pointers to specific files that is consider authoritative as to the users intent, and then builds out files in docs/goals. That then feeds into a plan ideation stage that results in directories for plans in docs/plans. That directory has the plan itself, and logs of revisions etc. So for now I'm just dumping snapshots of those jsonl line files in there.

Putting it in a branch so it doesn't pollute your checked out copy may well be a good idea in the longer run. For now, I keep all the plans available, as I then have a review stage that reviews all the plans, and writes things like "the user got increasingly exasperated as the agent kept ignorning direction" :D and helps propose improvements to the tool and workflow to reduce the number of those exasperated movements...

I'm thinking of packaging it up and open-sourcing it. It's all very experimental and likely to totally change every day for now, but I find it helpful. It's built me a personal dashboard, and keeps adding stuff to it with relatively minimal direction beyond "spying" on my notes and journal at this point. At one point a plan specifically called me out for procrastinating and planned for how to "work around" that with tooling (I wish it'd succeed at that).

There's nothing really fancy here, just feedback loops that ensures the wild claims the agents sometimes will make are tested and rejected.

To the original JSONL bit, the uuid you need to look it up is also the UUID you need to call "claude --resume [uuid]", so extracting it also allows for e.g. having the verification agent (that checks if the implementation agent was truthful when ticking off the quality gates - spoiler: it very often isn't) feed its report back into the original implementation conversation if rejected, instead of having the implementation agent "start over" without the full context. I haven't tested that yet, but I'm hopeful.

Though even if you don't have it restart, you can point it to the snapshot of the previous conversation as a source of additional info, as another option.

Probably the least unhinged theory in this thread, but unfortunately it doesn't make a lot of sense to me. If they had intel about such a threat, they'd have to move all high value assets to another base pronto. A flight ban won't stop a shady box truck from rolling into town and releasing a swarm of small drones.

(It would also be uncharacteristic of Iran to actually attack America directly, on American soil. Try to find examples of Iran doing that and you'll come up quiet short.)

> giving their credit card at restaurants and show their ID at events

I've only had people look, glance, or swipe.

You're doing it wrong when you let them take a photo of you, your license, and your credit card whilst providing an email, your phone number, and agree to receive texts in order to get a code to proceed. Leave when they provide you an AUP, TOS, or privacy policy you must agree to prior. Stop staying for 30-days per their requirements, let them prance you around to God knows where like you're their property, asking them to wait whilst you research any involved, or worry about what happens when they're bought out.

When they hand it back saying you're a bot, or it's been refused, give them a daft look then try again. When their systems are down, meaning they can't see, don't try again when told to since vision doesn't work that way. What do I know though since you wouldn't shock me if you handed them your house keys instead, provided someone to escort them there, and then thanked them for their business. Hate to break it to you, but your line was missed, lost, ran off, or left you with the other lost souls in Baffleland.

>As a European: nice, but why is it so BIG? How is that monster called "mid-size"?

Because it's a nominal size more than a descriptive one. Midsize is the second biggest size with only "full size" stuff being bigger.

It made more sense 30-40yr ago when people who remembered when the domestic auto makers mostly only made a full-size, a midsize and a compact car were still alive and of prime car buying age.

I had a USB that I carried around with me with a whole bunch of portable apps on it. That allowed me to have some kind of "standard environment" I could rely on.

I've since migrated to Linux 100% (outside of work) and whilst there are the odd annoyances, it's been a breath of fresh air compared to Windows. And I can have a good chuckle almost once a week these days with each new Windows consumer hostility coming across the HN front page.

I am not a physicist either but isn't the smallest unit of distance planck's length?

I searched what's the smallest time unit and its also planck's time constant

The smallest unit of time is called Planck time, which is approximately 5.39 × 10⁻⁴⁴ seconds. It is theorized to be the shortest meaningful time interval that can be measured. Wikipedia (Pasted from DDG AI)

From what I can tell there can be smaller time units from these but they would be impossible to measure.

I also don't know but from this I feel as if heisenberg's principle (where you can only accurately know either velocity or position but not both at the same time) might also be applicable here?

> A physics equation might tell you a particle moves Pi meters in sqrt(2) seconds but are those even possible physical quantities

To be honest, once again (I am not a physicist) but Pi is the circumference/diameter and sqrt(2) is the length of an isoceles triangle ,I feel as if a set of experiment could be generated where a particle does indeed move pi meters in sqrt(2) meters but the thing is that both of them would be approximations in the real world.

Pi in a real world sense made up of the planck's length/planck's time in my opinion can only be measured so much. So would the sqrt(2)

The thing is, it might take infinitely minute changes which would be unmeasurable.

So what I am trying to say is that suppose we have infinite number of an machine which can have such particle which moves pi meters in sqrt(2) seconds with only infinitely minute differences. There might be one which might be accurate within all the infinite

But we literally can't know which because we physically can't measure after a point.

I think that these definitions of pi / sqrt 2 also lie in a more abstract world with useful approximations in the real world which can also change given on how much error might be okay (I have seen some jokes about engineers approximating pi as 3)

They are useful constructs which actually help in practical/engineering purposes while they still lie in a line which we can comprehend (we can put pi between 3 and 4, we can comprehend it)

Now imaginary numbers are useful constructs too and everything with practical engineering usecases too but the reason that such discussion is happening in my opinion is that they aren't intuitive because they aren't between two real numbers but rather they have a completely new line of axis/imaginary line because they don't lie anyone in the real number plane.

It's kind of scary for me to imagine what the first person who thought of imaginary numbers to be a line perpendicular to real numbers think.

It literally opened up a new dimension for mathematics and introduced plane/graph like properties and one can imagine circles/squares and so many other shapes in now pure numbers/algebra.

e^(pi * i) = -1 is one of the most (if not the most) elegant equation for a reason.

>(type 3 in Chomsky's hierarchy)

*CRINGE* -- That didn't age well. ;)

Once you get past all the stuff about getting seduced by and sucking up to a pedophile, then giving him advice about handling media scrutiny:

- Chomsky hierarchy is about languages, not systems

- "Regular" doesn’t mean "safe", "simple", or "non-Turing complete"

- and it's dated because parsing theory moved on (and the hierarchy was always the wrong hammer)

I found a simpler explanation for what's going on [1].

To summarize, malicious Markdown files with custom schemes in URLs can trick users into executing arbitrary code. I honestly didn't know this was a "feature" of Notepad.

I guess that's my real problem here. The constant desire for feature bloat inevitably introduces potential vulnerabilities. In no world did I expect Notepad to have the ability under any circumstances to make network requests and execute arbitrary code.

Nor should I.

As an aside, this is why I violently despise Eletron apps and anything that runs its own browser engine for a GUI. I just don't want that level of attack surface in any app that I use.

Wikipedia has a bizarre symbiotic relationship with "archive sites".

First off, Wikipedia's articles that rely on mainstream news outlets are the worst articles. The editors specifically blacklist any outlet that doesn't match their systemic bias, and then they aggressively demolish paywalls in order to cram gossip and half-truths into their articles.

So Wikipedia and the WMF are projects which rely on copyright to exist. Their Creative Commons licensing is a shining beacon of liberty and the best complement to F/OSS such as MIT, GNU, and Apache. The WMF relies on generous donors, and their projects rely on tireless volunteers to keep the gears turning in there. The Commons are free because they are protected by international law, and respected by the Internet community.

But ironically, the "Internet archives" they rely on to preserve "reliable sources" are the antithesis of this. How would Wikipedia/WMF feel if their donations were robbed, and their volunteers uncredited? How would they feel if their websites and resources were weaponized against the laws and institutions which had built them? All these archive sites simply scrape away the funding sources and context for attribution. Newspapers and TV news aren't dying because of archive.org, but they sure ain't helping the situation.

Wikipedia pro-actively ensures that sources are scraped and archived. There are bots which go and check references. If any are dead, the bots find archived versions, and slot them in. If the link is not yet dead, the bots initiate requests to archive them ASAP. The Wikipedia community has established consensus to endorse this constant archiving activity as an integral part of the project, despite the 3rd-party nature operating in the shadows.

This particular beef of doxxing attempts and weird custom DDoS attempts is passing strange. Is this random civilian blogger heroic or righteous in a quest to uncover and reveal someone else's identity? Is the "archive" righteous to ... weaponize its own queries against some random civilian's website? Did we really expect any ethical behavior from either side in this melee?

Google and the archives are being used as a cudgel against copyright holders. Wikipedia has quietly stood behind these scrapers and cheered them on, as they chip away at the meaning of copyright itself. If information wants to be free, then Wikipedia must hold its Creative Commons licensing in contempt.

Wikipedia has huge verifiability problems. Many of their "best articles" have come to rely chiefly on "offline sources" also known as "dead trees in libraries and bookstores". The other articles rely on "paywalled sources". Headlines are not reliable but quoted. Errata are published but unnoticed.

You would need to be a wealthy billionaire to begin verifying half of the citations in Wikipedia today. You would maintain hundreds of subscriptions, proximity to comprehensive libraries, and own out-of-print volumes such as are not found in Google Books or amazon.com. And I suspect that you would find huge discrepancies between what the Wiki articles say and what the sources support!

I suspect most places that experience regular heavy snow, deal well with it.

I have a friend that went to school in Buffalo, NY. That’s a city that experiences “lake effect” snow, during the winter.

He says all the sidewalks are basically “snow gorges,” but the roads clear quickly, and everyone knows how to dress for the cold.

He tells me a story about visiting northern Quebec, one summer, and seeing houses with a second front door, set on the second floor, and was told they were “snow doors,” for deep winter, so folks can get out, when the snow gets deep.

We tend to adapt well.

This is fantastic. I recently regained an interest in revisiting Feynman lectures but several audios I found on YouTube left me uneasy that they could be AI-generated. I aimed to ensure good sources before diving in again, but hadn’t yet had the opportunity to do so.

The videos are particularly interesting in how they include a transcript which is auto-highlighted and one can click around the text to move in the video. That’s a great mode of interaction I wish were more common. I have only found it in Apple’s WWDC videos.

It’s missing a way to link directly to a timestamp, and when switching videos from the tabs the URL doesn’t change, but those are minor inconveniences considering the rest of the website.

Also kudos on choice of using the structure of the atom image as the “loading” graphic.

Thank you to the authors for putting this together.

There might be a confounder though, with the causality working backwards.

Rural housing is way cheaper than urban housing.

Urban cultural offering is way more lively than rural cultural offering.

If you want kids you need space, and have no time for fun, so you optimize. You stop paying for cultural offering you don't need, and opt for cheaping housing you do need.

Doesn't mean that urban/rural life makes you have children, rather the opposite. The choice in having children dictates whether you choose rural or urban life.

Not saying it's like this, just offering an alternative theory.

R2's dimensions are 185.6" x 75" x 66.9". The 2026 RAV4 is 181" x 73" x 66.5". So the R2 is slightly bigger than a RAV4.

The R1S is significantly larger at 200" x 82" x 77.3".

Notepad rendering other formats removes one of the specific reasons I use notepad: to strip the stupid formatting that all sorts of applications seem to want to attach to text these days.

Notepad handily strips away all the custom link namings and formats that totally fuck the expected output of a simple copy and paste. That's a big part of the its magic: it's immunity to the choices of marketing teams and dud management.

This was also my understanding.

It's essentially like "cracking" a password when you have its hash and know the hashing algorithm. You don't have to know how to reverse the blur, you just need to know how to do it the normal way, you can then essentially brute force through all possible characters one at a time to see if it looks the same after applying the blur.

Thinking about this, adding randomness to the blurring would likely help.

Or far more simply, just mask the sensitive data with a single color which is impossible to reverse (for rasterized images, this is not a good idea for PDFs which tend to maintain the text "hidden" underneath).

Yes, totally true. This is dangerous though when those circumstances change and basically invalidate the whole category.

I can think of NFT infrastructure here:

Various product categories were created with market leaders that owned them.

But the NFT hype didn’t hold and we effectively realized the use cases didn’t manifest beyond ZIRP-driven speculation and a small collector-artist scene.

So that can negate the whole category or crown a different winner when a technology changes.

Imagine if we used NFTs to verify if an AI or human made a piece of media.

Suddenly “marketplace” becomes a much less interesting category than scalable, fast APIs to create NFTs

I've still got the very fast muscle memory of "Alt-F S", I used to do it habitually in Word and Excel. Still do it occasionally, then having to then undo whatever it does now (luckily it's usually nothing), but sometimes it leaves the Alt press 'open' so the next letter I press does something unpredictable.

What's with all the AI fear mongering and doomspeak? Feels like people have never been so excited about getting laid off and becoming obsolete. It used to be that workers fought for their rights but maybe decades of software engineering proliferation has dampened that survival instinct. These days feels like OpenAI is paying writers to scare as many people into believing they're no longer needed.

I also find it kind of funny that the only perspective on AI is about being laid off. This says a lot about who's writing all these articles. But beware the cobra effect https://en.wikipedia.org/wiki/Perverse_incentive . If the AI boom allows a company to lay off a large amount of its engineers the engineers can also simply band together and as-easily become a competitor unburdained by legacy code resulting in profits going down for existing businesses. Alternatively they can simply join the customers of various SaaS businesses and roll their own solution with same net effect.

For people who read this parent comment and are tempted to say “well of course complex numbers can be ordered, I could just define an ordering like if I have two complex numbers z_1 and z_2 I just sort them by their modulus[1].”

The problem is that it’s not a strict total order so doesn’t order them “enough”. For a field F to be ordered it has to obey the “trichotomy” property, which is that if you have a and b in F, then exactly one of three things must be true: 1)a>b 2)b>a or 3)a = b.

If you define the ordering by modulus, then if you take, say z_1 = 1 and z_2 = i then |z_1| = |z_2| but none of the three statements in the trichotomy property are true.

[1] For a complex number z=a + b i, the modulus |z|= sqrt(a^2 + b^2). So it’s basically the distance from the origin in the complex plane.

One of the last straws that got me to migrate to Linux was how long it would take for calc.exe to open in Windows 10. Even on much older computers and much older version of Windows it was instant. Suddenly in the mid-2010's the calculator is so bloated you have to wait a few seconds for it to load? Fuck off.

It didn't always take a long time to load, but often enough that it was noticeable and 'worrisome' for the future of Windows.

There is a difference between a bug you laugh at and walk away and a bug a scammer laughs at as he walks away with your money.

When I open something in Notepad, I don't expect it to be a possible attack vector for installing ransomware on my machine. I expect it to be text. It being displayed incorrectly is supposed to be the worst thing that could happen. There should be no reason to make Notepad capable of recognizing links, let alone opening them.
