Wow this is interesting. I launched my site like a week ago, only submitted to google. But all the crawlers (especially the SEO bots) mentioned in the article were heavily crawling it in a few days.

Interestingly, openai crawler visited over a 1000 times, many of them for "ChatGPT-User/1.0" which is supposed to be for when a user searches chatgpt. Not a single referred visitor though. Makes me wonder if it's any beneficial to the content publishers to allow bot crawls

I ended up banning every SEO bot in robots.txt and a bunch of other bots

>> The alternative is to list on a pink sheet exchange

Nah, there's OTC which is different than pink sheet. There's a couple of levels of OTC above that, between the pink sheets and the exchange traded stocks.

Plenty of OTC stocks have graduated, plenty of respectable stocks have gone from exchange traded to penny stock status and back.

Pink sheet stocks though? I don't know. Who buys those? Postmen? There's always postmen.

CAs and certificate consumers (browsers) voted in favour of this change. They didn't do this because they're incompetent but because they think it'll improve security.

It's really not that hard to automate renewals and monitor a system's certificate status from a different system, just in case the automation breaks and for things that require manual renewal steps.

I get that it's harder in large organisations and that not everything can be automated yet, but you still have a year before the certificate lifetime goes down to 200 days, which IMO is pretty conservative.

With a known timeline like this, customers/employees have ammunition to push their vendors/employers to invest into automation and monitoring.

Lemme tell you about a client who confronted his therapist in 2019 about how using non-clinical political personalities as reference points was eroding the feeling of trust - and also that pathologizing public entities without clinical access projects weak professional ethics.

And six years later the same client said “I don’t care anymore, say whatever you like, and I will explain how you may be projecting your personal fears on me.”

One might argue that masks are necessary because the state is surveiling people and abducting them off the street based on viewpoint. If you're expressing views in public, it would behoove you to do so while obscuring your identity to the extent possible, lest you end up in a Salvadoran death camp for expressing views disfavored by the regime.

Check out this recent benchmark MTOB (Machine Translation from One Book) -- relevant to your comment, though the book does have parallel passages so not exactly what you have in mind: https://arxiv.org/pdf/2309.16575

In the case of non-human communication, I know there has been some fairly well-motivated theorizing about the semantics of individual whale vocalizations. You could imagine a first pass at something like this if the meaning of (say) a couple dozen vocalizations could be characterized with a reasonable degree of confidence.

Super interesting domain that's ripe for some fresh perspectives imo. Feels like at this stage, all people can really do is throw stuff at the wall. The interesting part will begin when someone can get something to stick!

> that's basically a science-fiction babelfish or universal translator

Ten years ago I would have laughed at this notion, but today it doesn't feel that crazy.

I'd conjecture that over the next ten years, this general line of research will yield some non-obvious insights into the structure of non-human communication systems.

Increasingly feels like the sci-fi era has begun -- what a time to be alive.

> Graduate School of Education

> School of Public Health

I must have missed the time when the Medical School racked up a record of egregious antisematism.

I wrote this on another thread recently, reposting here:

Things started to make more sense to me once I realized that by nature, human beings hate freedom and love tyranny. Once you accept this, it all falls in place. Deporting citizens to foreign prisons? Sounds great. Incoherent foreign and economic policy? Love it. Freedom of the press? Who needs it! Destruction of democracy? Own the libs! Legalize bribery of foreign officials? Even the playing field! And finally, words don’t need to mean anything because they are simply evocations intended to stir up certain emotions. They are more akin to a hunter’s duck call. The hunter doesn’t speak duck and doesn’t care whether that sounds he’s making have any meaning, he simply makes noise and looks for a result. Not getting the desired result? Just change the noise a little.

This is why democracy will eventually fail and autocracy will rise in its place. And no one will ever learn.

It sounds like you don't really know if they are being discriminated against, even though you are stating it as fact. The 3% number could be biased due to any number of reasons, conservatives may not apply to Harvard for ideological reasons, or student ideologies may shift during education.

It's possible that you can identify right-wing high schoolers based on their writing, but I don't really see a problem with rejecting students if they are touting unpopular and/or discriminatory ideas. Universities have the right to maintain a culture of openness and learning, and conservatism is often antithetical to that.

Yup. I genuinely don't see any reason to fight this hard against it othewise. Basically, something about the release or status of Garcia must be so horrid that even for Trump its a convictable scandal. so:

1. he'd dead and he pushed to make sure he had no due process

2. He's in such a near dead state that it would spark outcry that may even penetratie the propoganda.

3. any unedtied footage of the prisons would bring immediate allusions to concentration camps and make enough of the conservative size realize the US is falling into facism,

As is, we may be risking a civil war over this.

If they bought both Instagram and Snapchat it would have been neutralizing competition. Instagram acquisition was just a business staying relevant after a youth market grew up and soured on them while the next younger ones wanted something else cooler designed for 100% around mobile.

I believe intention and behaviour matters much more to antitrust than simply continuing to be a dominant market leader by smartly staying on top of what the public wants. Google search doing horizontal integration into Android and Chrome to cut off competition's market entry points at lower levels is far more plausible antitrust narrative IMO.

There are loopholes to roll all sorts of nonsense into an IRA though. There was a whole news cycle in the 2012 election about Mitt Romney's $4M "IRA" or somesuch. And IRAs are hardly the only shelter from income tax, they're just the most obvious.

The simple truth is that wealth beyond the ~$10M level in the US pays essentially zero "income tax". It just doesn't happen, no one does it. Short term gains are only taxed for small investors who don't know any better.

I've seen a bunch of requests with forged ChatGPT-related user agent headers (at least, I believe many are forged - I don't think OpenAI uses Chinese residential IPs or Tencent cloud for their data crawling activities.)

Some of the LLM bots will switch to user agent headers that match real browsers if blocked outright.

I hear this a lot, but in my experience this isn't true at all.

A Versal AI Edge FPGA has a theoretical performance of 0.7TFLOPs just from the DSPs alone, while consuming less power than a Raspberry Pi 5 and this is ignoring the AI Engines, which are exactly the ASICs that you are talking about. They are more power efficient than GPUs, because they don't need to pretend to run multiple threads each with their own register files or hide memory latency by swapping warps. Their 2D NOC plus cascaded connections allow them to have a really high internal memory bandwidth in-between the tiles at low power.

What they are missing is processing in memory, specifically LPDDR-PIM for GEMV acceleration. The memory controllers simply can't deliver a memory bandwidth that is competitive with what Nvidia has and I'm talking about boards like Jetson Orin here.

If you read the exact report, you realize why you want to be cynical.

No one was actually met with, no was even called. The lawyer constantly use language to the effect of "to my understading" as means to try and distance himself as far from the case as possible to minimize any potential contempt/sanctions on his end.

No one in America legitmately knows what's going on as of now. Maybe Trump does now but we know how that goes.
Show HN: AES-256 brute force using structured logic (UUIDs and xy = x/y rule)
by polymetron | 2025-04-15 00:38:50+00:00
I’ve been experimenting with structured logic as a way to frame search spaces — not in an academic way, just as a personal project.

I wanted to know: what happens if you initialize a brute-force run with a simple equality like xy = x / y? Not as a filter, just as a logical ignition point.

I used AES-256-CBC encrypted files with UUID passwords and tested against a 1 million UUID space. It cracked it in under 40 seconds. Then I scaled it to a 1 billion UUID range, and it still found the key without issue.

This isn’t a crypto tool, and I’m not trying to solve any cryptographic problems. I’m just curious if deterministic logic applied to large search spaces can be useful.

Repo’s here if anyone wants to take a look or test it themselves: [https://github.com/ElSolem/project_oceans]

Feedback welcome — and open to hearing where this kind of structure-first approach might apply.

> That's exactly the same as my intrusive structure, no?

It's not, for the reason they put in parentheses:

> note: no pointers in user_data_t

An allocation of user_data_t also allocates space for payload_t, rather than just allocating space for a pointer to payload_t. Your structure requires an additional allocation to point the payload_t* at something. The fact that they hid the next node_t* in a struct doesn't matter though.

I loved temu, aliexpress, and shein. I probably averaged 1 item per day arriving to my house, for years and years. Mostly little electronics parts and specialized tools for my workshop. Buying from Amazon or locally would have cost me 10x as much. Obviously it's over now. Anyone getting a package in May will be hit with a $75-$150 or more bill per package, even a 75 cent envelope will be charged +$75. I feel bad for the unaware people still ordering. I'm surprised the websites don't even acknowledge this yet. I guess they are hoping for a reversal in the next 2 weeks.

I'm not sure I understand the distinction between "high-entropy macrostate" and "order". Aren't macrostates just as subjective as order? Let's say my friend's password is 6dVcOgm8. If we have a system whose microstate consists of an arbitrary string of alphanumeric characters, and the system arranges itself in the configuration 6dVcOgm8, then I would describe the macrostate as "random" and "disordered". However, if my friend sees that configuration, they would describe the macrostate as "my password" and "ordered".

If we see another configuration M2JlH8qc, I would say that the macrostate is the same, it's still "random" and "unordered", and my friend would agree. I say that both macrostates are the same: "random and unordered", and there are many microstates that could be called that, so therefore both are microstates representing the same high-entropy macrostate. However, my friend sees the macrostates as different: one is "my password and ordered", and the other is "random and unordered". There is only one microstate that she would describe as "my password", so from her perspective that's a low-entropy macrostate, while they would agree with me that M2JlH8qc represents a high-entropy macrostate.

So while I agree that "order" is subjective, isn't "how many microstates could result in this macrostate" equally subjective? And then wouldn't it be reasonable to use the words "order" and "disorder" to count (in relative terms) how many microstates could result in the macrostate we subjectively observe?

Tangent. I got into building hi-fi tube amplifiers some years back. Part of it was a kind of nostalgia for the days of Heath-Kit which I am only just old enough to remember the company's sunsetting years.

It was a fun few years deep-diving into the various amplifier topologies, buying NOS vacuum tubes on eBay, looking through electronics flea markets for parts. I made several amps, tried different tubes, topologies.... Eventually I settled on a small stereo amp and designed a PCB for it, created a small kit even.

Using a drill press in the garage, a table saw to cut aluminum sheet stock down, even learning to powder-coat parts in a toaster-oven I picked up from Walmart, I made increasingly nicer looking amps. With two large output transformers and an even large power transformer they were fairly heavy beasts.

Nonetheless, though I built them a decade or more ago, every one of the amplifiers I built are still in use today. The music I am listening to at this moment is coming from one. Another is down in my "lab". I have given several away to friends, co-workers in the past.

I guess the reason for the tangent was to say that I did indeed find that when you have (or make) a thing of real quality it can last … perhaps a life time?

And thinking again a little nostalgically, I like that too about electronics just up to the post-modern era: a new electronics purchase might have cost you a paycheck or two, but you got I think more mileage out of that device.

EDIT: come to think of it, the heavy iron transformers are from the U.S., the tubes NOS from U.S. WWII bombers. I didn't built them of course with tariffs in mind, but surprisingly they are not so cost-dependent on overseas suppliers.

And here's a photo of the finished amp (from when I once considered selling the kits): https://imgur.com/PBKOQMk

To be clear I'm advocating that if someone is flagging this due to it not being intellectually interesting, that they reflect on whether that's actually true or if it's just that fear or anxiety are getting in the way.

I certainly don't want all news on this topic to be here; there's plenty of places to get that. But we definitely could discuss it here in ways which aren't accessible many other places if we take on the rather difficult task of finding some curiosity about the what exactly is going on.

Universities and colleges are hotbeds of political protest. Take young people with poor impulse control, expose them to education and political literature, and let them freely associate (e.g. form student groups). They're going to question authority and government policy, often in an unruly manner. That's just how it goes. The thing is, when students are right, protests often spread to the rest of the population. That's why the letter makes explicit a concern about non-students being invited onto campus. The last thing any administration wants is for student groups to spark a big protest that sticks around for a bit and pulls in protesters from off-campus. That stuff will make the news every time!

Most governments recognize that large protests can influence public opinion against them. If you let such a protest occur and do nothing to satisfy the demands of the protesters, then things can get ugly quick. Freedom of speech and association are powerful things! There's not much an open, democratic government can do except respond to protests by addressing the underlying issues or crush the protest and hope that the public decides the protesters were wrong. What the Trump administration is trying to do here is reduce their risk by infringing on freedom of speech and association. It's fascist or totalitarian. Take your pick.

As for their claims that they're trying to "unwind enforced ideological conformity"... You can't do that by enforcing conformity to a different ideology, as they are attempting here. This is a case where you should pay less attention to words and more to actions.

It's tricky when you think of a continuous system because the "differential entropy" is different (and more subtle) than the "entropy". Even if a system is time-reversible, the "measure" of a set of states can change.

For example: Say I'm at some distance from you, between 0 and 1 km (all equiprobable). Now I switch to being 10x as far away. This is time-reversible, but because the volume of the set of states changed, the differential entropy changes. This is the kind of thing that happens in time-reversible continuous systems that can't happen in time-reversible discrete systems.

I think what we're going to see is that republicans won't receive much blame for groceries and consumer good costs rising. I also think outside of extreme events (e.g. COVID) the vast majority of the voting public doesn't really understand how to judge the health of the economy, and instead only defers to the economy as a post-facto rationalization for what they were already leaning towards.

The tariff chaos is on everyone's mind right now so it seems as if people genuinely care, but in reality it's just a function of the media attention cycle. By the time the next elections come along, complaining about tariffs is going to be a boring talking point that democrats mistakenly think is a winner, but the public will have already moved on to the next thing.

Hard to prove something's lack of existeance.

But from what I roughly understand, Xinis own documents don't have direct reference to a contract. They rely on AP's reporting of such a contract. So it's legally pretty ephemeral as of now.

Yet another law brokenm since such foreign treaties and contracts should be publicly documeted. But what does that matter at this point?

Similar story: mom had a melanoma removed from her foot. multiple lymph node biopsies and other tests said it had been successfully removed.

She went back once a year for checks for 4-5 years. It was only when she was called into see an oncologist and told an unrelated x-ray lead them to discover she had stage 4 metastatic melanoma (brain, liver, spine, femur, lungs and i’m sure i’m forgetting something) that we found out that they’d only been giving her visual checkups each year, no PET scans or anything else. The oncologist was shocked that the checks were so basic, mom didn’t know she was supposed to have anything else and she was dead in about 8 weeks.

We were told that the form of melanoma only came back like that in 1% of patients and usually simple visual checkups were enough. I have no idea how true that is.

Yes, perhaps the government should subsidize (or allow states to subsidize) the fixed costs of mail, just as we subsidize the fixed costs of roads, so that our business can be competitive. Is this what China does domestically, or what the US does when we charge for international shipping? Point is, we should at least list all the ways that we can be more competitive, rather than cheering isolationism that makes us all worse off.

This is not a solution for now, but a solution for 'next time', but can you migrate to using 'virtual credit cards' where you can essentially use a separate credit card number per subscription. In cases like this, you just cancel the credit card number that's been "burned", but you don't have to re-jig all the other subs to use a new number.

(ie. the advice for this situation is cancel the credit card, knowing that's a giant pain in the arse).
