Thanks for the great question! We actually use a reasoning-based, vectorless approach. In short, it follows this process:

1. Generate a table of contents (ToC) for the document. 2. Read the ToC to select a relevant section. 3. Extract relevant information from the selected section. 4. If enough information has been gathered, provide the answer; otherwise, return to step 2.

We believe this approach closely mimics how a human would navigate and read long PDFs.

It's owned by a few rich corporations and individuals. It isn't available to anyone - only to those they choose and are ready to pay them. And it isn't open source at all, because open source is not reuse without any obligations (even under permissive licenses). And let's not forget that they 'open' only FOSS works and individual works. They never expose proprietary IP belonging to rich corporations. It isn't an emerging method of collaboration - it's another method for wealth consolidation.

In India, Amazon has been quite good IFF you have Prime. Deliveries are quite quick, returns and refund rules are clear, and always get processed if eligible. If you're a frequent user, it's well worth the subscription cost.

If you don't have Prime though, it's a different place altogether. But you don't have much of a choice - Flipkart (the other alternative) is worse in every way.

> The M1 Ultra doesn't have 800GB/s because it's "integrated", it simply has 16 channels of DDR5-6400, which it could have whether it was soldered or not.

The M1 Ultra has LPDDR5, not DDR5. And the M1 Ultra was running its memory at 6400MT/s about two and a half years before any EPYC or Xeon parts supported that speed—due in part to the fact that the memory on a M1 Ultra is soldered down. And as far as I can tell, neither Intel nor AMD has shipped a CPU socket supporting 16 channels of DRAM; they're having enough trouble with 12 channels per socket often meaning you need the full width of a 19-inch rack for DIMM slots.

It turns out that actuaries are pretty decent at the math side of these things. It's just that being a motorcycle rider, regardless of how safe you personally are, is dramatically more of a risk to insurers than covering a cage driver. They know that because they have access to all the data behind the claims and payouts that normies like us don't have access to. Literally everyone believes that they are the exception to things like these. That's the difference between an anecdote and data however. Insurance companies rely on data and not your word that you're the exception to the picture that all their data paints.

Doing something like hooking it up with a suicide cord is asking for absolute shitheaps of trouble. If you are feeding your outlets, you run the very real risk of backfeeding the grid and electrocuting an unfortunate lineman when the power goes out. You've basically got to get the utility to do this for you, as you need a real transfer switch and their explict buy in, as the only safe and correct way to do this is on the utility side of the distribution box. Doing that basically means getting setup to feed back to the grid as far as I've seen anyways.

> cause problems

Let's be very clear that "cause problems" in the context of HOAs means things like planting flowers on their private property that the HOA psychopaths don't like, or painting their house the "wrong color" or parking "unapproved vehicles" on their very own private property.

HOAs are a cancer on society and need to be outlawed, except for the very limited case of maintaining common areas.

As I read it, the point of mentioning Dual EC is to show a previous case where NSA have acted in a way that reduces security for hand-wavy reasons, in addition to the DES case where they did the same.

And now, in a world where QR + pre-QR algos are typically being introduced in a layered fashion, they're saying "let's add another option, to reduce the number of options" which at least looks very suspicious

Practical quantum computers are probably not very close, but you can certainly use the fear of them as a chance to introduce a new back-door. If you did, you'd have to behave exactly as the NSA is doing right now.

This argument doesn't account for the inherent, drastic power imbalance between the average participant of gambling and the average owner of a gambling center.

Gambling between people, a basement poker game, that's fine, that's no one's business.

Handing your money over to rich people operating black boxes that are designed from ground up to mesmerize and mind control you into emptying your wallet is a totally other story. On the individual level, it ruins the lives of anyone who is unable to resist or understand the psychological tricks employed on them. Zooming out, it destroys families, communities and in effect, societies.

If we are going to base the legality of gambling on consent and human rights, we have to recognize the limit where consent is no longer valid, due to sickening engagement tactics.

Someone's freedom to make money off of my ignorance or weakness does not supersede my right to self-determination and well-being, neither of which are possible when being hoodwinked by exploitative capitalists.

If we are to continue allowing corporate gambling operations and 24/7 mobile sports betting, we need to place serious restrictions on how these companies are allowed to operate.

A huge part for me is how they handle employees and how that makes employees steal things.

My wife ordered an iPhone and we received a salt mill and a flashlight. Called them, they said sorry send it back. But then they would not return the money cause we did not return the phone. At that point Amazon accused us for betrayal and forced us to take a lawyer to get parts of the money back.

That was our last day of using Amazon or prime video.

If you're not familiar with how teletype machines worked you might enjoy it. There were early units that were purely electromechanical. It's really cool.

Usagi Electric did a nice video if that's your kind of thing: https://youtube.com/watch?v=sSiVYgot9SI

I think the video does a nice job of showing the mechanical components that encode the keypresses and generate the 45.5 baud serial output. The printing side isn't given quite as much coverage but you do get to see close-up views of it in operation.

The one I was referring to was from this paper, first published in May: https://arxiv.org/abs/2505.20211v1

I don't recall how I found out about it, but it was either paperswithcode or an LLM research session working through the intruder dimensions problem.

In my Stable Diffusion tests, it substantially improves LoRA training speed and fidelity, though I've got some experiments that seem to even further substantially improve on it by adding learnable rotations of the singular vectors.

Why don't we hybridise all crypto? We'd get more security if we required RSA+ECDSA+ED25519 at all times, right? Or is the answer that the benefits are small compared to the drawbacks? I am unqualified to provide an answer, but I suspect you are also, and the answer we have from a whole bunch of people who are qualified is that they think the benefits aren't worth it. So why is it fundamentally and obviously true for PQC? This isn't actually an engineering hill I'd die on, if more people I trust made clear arguments for why this is dangerous I'd take it very seriously, but right now we basically have djb against the entire world writing a blogpost that makes ludicrous insinuations and fails to actually engage with any of the counterarguments, and look just no.

I believe that the solution here is to make crashes "safe" eg with a supervisor process that should either never crash or be resumed quickly and child processes that handle operations like user inputs.

This together with the fact that the main benefit of range types is on the consumption side (ie knowing that a PositiveInt is not 0) and it is doable to use try-catch or an equivalent operation at creation time

I actually fail to see how the occupation of Gaza and the West Bank violates international law (not that international law means anything), aside from the obvious fact that they weren’t outright annexed after 1967, when Israel was on rock-solid legal ground to just annex the entire place (nothing in the international law prohibits a country from annexing territory won in a _defensive_ war).

This is amazing. I recently got a Go 2 (no stylus but want one). I am a little apprehensive of Win 11, so until I am sure, I am duel booting with Fedora (which is working fine for most part).

> Are there any recommendations for stylus being used on MS hardware but running linux?

All references (understandably) assume windoes but there is literally no report that I could find for machines running linux. I am even unsure weather the requirements are purely hardware bound or also require proper software. Any help will be appreciated.

The branch of mathematics you need to compute the bounds of the result of an operation is called Interval Arithmetic [1]. I'm not sure of where its limits are (hah), but at the very least it provides a way to know that [0,2] / [2,4] must be within [0,1].

I see there's some hits for it on libs.rs, but I don't know how ergonomic they are.

Show HN: AI Prompt Copy – curated, one-click prompts (no login)
by kuzej | 2025-10-05 07:42:26+00:00
I built a small site to make copying AI prompts painless: a curated library you can browse by tags and “Hot Trends,” with one-click Copy and Share on each prompt. No account required.

What’s inside:

* Curated prompts from a public GitHub-sourced collection plus community submissions. * Tags/collections to scan fast; “Most copied this week” to surface what people actually use. * One-click Copy and short share links for teammates. * A simple “Suggest a prompt” to contribute back.

I’d love feedback from HN:

* Is the tag taxonomy/search sensible? What’s missing or noisy? * What would make this more useful to you (API, browser extension, better trend signals)? * If you spot low-quality or infringing prompts, tell me and I’ll remove them quickly.

Link: [https://aipromptcopy.org](https://aipromptcopy.org) Happy to answer questions and share details.

To go further, there is an inherent expectation that the president might go against the wishes of the people, which is why we have two other branches of government designed to enforce checks and balances.

This check and balance system has completely failed due to mass coordination, but the idea is that individual governmental positions have theoretical pressures against corruption, the possibility of corruption is built right into our Constitution.

Very mixed feelings about this as there’s a strong case for the decisions made here but it also moves .NET further away from WASMGC, which makes using it in the client a complete non-starter for whole categories of web apps.

It’s a missed opportunity and I can’t help but feel that if the .NET team had gotten more involved in the proposals early on then C# in the browser could have been much more viable.
by bitwize | 2025-10-05 07:43:38+00:00
.NET was always a clusterfuck of naming, as in the early 2000s Microsoft was slapping the .NET label everywhere. .NET Passport (now known as Microsoft accounts), .NET My Services, Visual Studio .NET (which was the same as regular VS, just with support for building C# and VB.NET apps added), .NET Server 2003 (Windows Server 2003), et weary cetera.

In this respect, as in many others related to .NET, Microsoft was inspired by Java. In the late 90s, Java wasn't just a language, it was a VM, runtime environment, enterprise platform (Java EE, now Jakarta EE), smartcard technology, remoting protocol, operating system, desktop environment, floor wax, dessert topping...

One limitation of the stack is that it needs to be contiguous virtual addresses, so it was often limited when devices just didn't have the virtual address space to "waste" on a large stack for every thread in a process.

But 64 bits of virtual address space is large enough that you can keep the stacks far enough apart that even for pretty extreme numbers of threads you'll run out of physical memory before they start clashing. So you can always just allocate more physical pages to the stack as needed, similar to the heap.

I don't know if the .net runtime actually does this, though.
by cake-rusk | 2025-10-05 07:44:13+00:00
Are you now allowed to benchmark the .Net runtime / GC?

Edit: Looks like you are allowed to benchmark the runtime now. I was able to locate an ancient EULA which forbade this (see section 3.4): https://download.microsoft.com/documents/useterms/visual%20s...

> You may not disclose the results of any benchmark test of the .NET Framework component of the Software to any third party without Microsoft’s prior written approval.

Isnt the root problem a company being able to A/B test the most addictive product? They spent huge amount of money to find all the psychological tricks, to identify who has gambling potential and then target those people.

Education wont beat that. Gambling is not a rational decision in the first place.

But, young men gambling (they are the primary target demographic) will make them into desperate and hopeless group. And not just financially, marrying or dating gambler is even bigger mistake then partnering with an alcoholic. Their lives will go down the drain in all aspects.

That’s the law, yeah - and if the goods are faulty it’s actually up to two years.

But this is Amazon - they don’t need to follow consumer protection laws - I think their specific get out is that they’re Amazon Spain, and I’m having stuff shipped to Portugal, and Spanish consumer protection regs (which implement the EU regs) only protect consumers in Spain.

That was meta’s get-out, too.

I've been an Amazon customer since the were just a book store (in 1999). I buy a lot of stuff from them.

Just in the past three months, I've noticed a lot of changes. Orders are being lost, orders are being cancelled by them for lack of product, orders are being split, with no indication of the split -- showing all products delivered when the split portion is still in transit.

In the past, the customer could see the same order information that their Customer Support staff could see, but now we can't see as much. Recently, I had an order split three ways (three of the same item) without any notice. The shipment arrived with only one item, so I contacted Customer Support. The support rep spun on it for a while, and then told me I would receive the remainder of the shipment the next day. By the end of the call, it changed to two days. It finally arrived four days later, but that shipment also only had one item (of the three ordered). I tried contacting customer service again, but instead of letting me reach a human, Amazon forced me into an AI chat. The chatbot told me that my only option was to accept a refund for the missing (third) item. I repeatedly told it that I would rather receive the item, but it insisted that was impossible. So it refunded part of my purchase price. Two days later, I received the third item (with no shipping status updates of any kind), followed the next day by a demanding email from Amazon that I pay them for the item I had received (which I did do).

Even more recently, I ordered an m.2 SSD. While placing the order, I opted for the "green" option to get a little money back by not rushing them. Everything was fine with the order until the next day, when I got an email saying the charge to my (Amazon) card was declined. I checked the card, which still had $8,100 of credit, and I had just received and paid the ($1,900) bill the day before. I called Amazon (and reached a person!) -- the guy in the foreign call center had an accent so think that I had trouble understanding him, but he insisted that the issue was MY fault three times before I got him to consider that maybe it wasn't. He offered to try charging the order again, and it went through. I checked the order status while still on the call, and the "green" option was no longer there, so I cancelled the order and tried re-placing it, but there was no longer any "green" option, so I didn't re-place the order.

I think all of this nonsense is a consequence of Amazon deploying AI into their systems across all business functions. The last one was probably an AI trying to maximize their margins by depriving me of the (1%) "green" credit. Hopefully my actions helped "train" the AI that ripping off your customers will reduce your sales revenue.

I know this was a long rant, but at least in my case, Amazon's deployment of AI is going to reduce the amount of money they earn from me.

Interesting site ! There is something playful in the idea of ambigrams that I can’t explain. Maybe something like a puzzle ?

A nice project could be to automate a generator. It must be quite hard because it feels like a mix between a Captcha and an AI hallucination but made right. The « glyph » search part of the site is maybe the best asset to start with a database of possible matches.

For the exploratory stuff I tend to use R in code blocks as I’m familiar with it. Sadly I’ve never really done much with Clojure, though its data capabilities always look very cool, especially datatomic. It’s just always been a bit of a poor fit for what I’ve been doing so I’ve never quite got round to it. Maybe this will give me the push I need!

Sadly the things where the extra tooling is missed is more in larger databases where I’m either rebuilding or restructuring an existing database or writing more complex queries to help with this and I want to do it all in the database. Hence autocomplete and general knowledge of the schema being built in is nice.

They took this down so quickly. Bad examples are great to learn from. I don't get all the hate, and it just seems like a bunch of bullies found out and put the red tape on it. Don't you think "burning a house down" is a vast over exaggeration? I wouldn't trust any professionals using such intimidating tactics.

Do they not teach "the boy who cried wolf"? It doesn't get worse than claiming this stuff will burn someone's house down around with everyone around them.

The genious leadership at prime video thought it would be a good idea to introduce adds not only on the beginning of movies but also in the middle of it, with an extra paid option (on top of prime) to remove it. When an add appeared I got so frustrated I cancelled my prime subscription at that very moment. I wonder if they even considered/cared about brand reputation impact.

When your stock price is so high that it out-values operations and out-paces innovation, and you need to provide value to your shareholders to retain your valuation, what can you do other than squeeze your revenue stream for more juice?

Hopefully Enshittification is just the dying throes of a megacorp before they implode - otherwise we are all screwed if this becomes the new normal.

Most likely Japan just have better customer protections. Amazon only able to sell open-nox and co-mingled knock-off crap because US regulators are toothless.

Louis Rossmann have a video about fake electrical fuses sold on Amazon US with almost half a million views. Literally the product that can burn your house to the ground:

Did Amazon US at least pulled these off store? Nope.

Haha! You could double down and up the stakes.

It’s not that it would need dynamic memory allocation (it could be done with static), but rather it’s not essential to performance—you could use any KV or OLGP for additional “user data”, it’s not the hard contended part.

To keep consistency, the principle is:

- write your data dependencies if any, then “write to TB last as your system of record”,

- “read from TB first”, and if it’s there your data dependencies will be too.

Before git abused the terminology, a branch used to refer to a long-lived/persistent commit lineage, most often implemented as a commit-level flag/attribute,

OTOH, git branches are pointers to one single commit (with the git UI tentatively converting this information sometimes into "that commit, specifically" or sometimes as "all ancestors commits leading to that commit", with more or less success and consistency).

Where it matters (besides fostering good/consistent UX) is when you merge several (topological) branches together: git won't be able to tell if you just merged A into B or B into A. Although the content is identical at code-level, the semantic/intent of the merge is lost. Similarly, once the head has progressed so much ahead and your history is riddled with merges, you can't tell from the DAG where the individual features/PR/series start and end. This makes bisecting very hard: while hunting down a regression, you would rather avoid checking-out mid-series commits that might break the build, and instead stick to the series boundaries. You can't do that natively with git. That also makes maintaining concurrent versions unnecessarily difficult, and many projects are struggling with that: have you seen for instance Django¹ prefixing each and every commit with the (long-lived) branch name? That's what you get with git while most other VCSes (like Mercurial, my preference) got right from the start.

So you've constructed a strawman. Another indication of ceding the argument.

> and the answer we have from a whole bunch of people who are qualified

The ultimate job of a manager or a board is to take responsibility for the decisions of the organization. All of your comments in this thread center around abdicating that responsibility to others.

> This isn't actually an engineering hill I'd die on

Could have fooled me.

> we basically have djb against the entire world

Many of your comments indicate to me that clashing personalities may be interfering with making the right engineering decision.

If they don't work the way you want, you just keep refining it. This is easy if you actually test your regex in real data.

Fail catastrophically.. I had that happen once on an unexpectedly large input. That was a fun lesson. Ironically, the solution was to (*FAIL)

In any case, I learned a lot and delegating that to an LLM and learning nothing would not have put me in a better position.

WordPress still has those, or are they disabled by now for new blogs? I get them from WordPress blogs sometimes instead of the nicer trackbacks, same thing without xmlrpc. Webmentions are an orthogonal newer system, basically incompatible trackbacks.

Serendipity implements all three now, so there are definitely still blog engines that support these mechanisms.
