Thank you for the feedback. Glad to hear it didn't go into detail on human anatomy. We haven't been able to get it to tell us where to find graphic videos of a man being shot to death, but we will keep testing and work to improve it.

We will do some more internal discussion on whether or not we want it to be the tool to provide emergency assistance. I'm not sure that's ethical. We have a team member with a decade of child education experience, but we can consider other advisors.

It is not like nth of a kind Hinkley Point C, EPR reactor number 5 and 6, at $32.5B per reactor is going any better?

Also do note that no one knows the true cost of Olkiluoto 3. The $11B figure is from a settlement many years before it was completed as interest and construction costs kept accumulating.

Not saying anything new here, but at the core there are only a few key reasons for using bitcoin: investment, hiding your finances, and the idealism of de-centralization.

The intrinsic value of decentralization is the ability to operate outside any fiat system of laws or government. So that one lines up a lot with the criminal side of hiding your finances. The investment aspect sure is enticing to lots of folks, but without a real core underlying value it's just bubbles and rug-pulls. So all this has the effect, wittingly or not, of lining up the incentives of all BTC users with money launderers.

Sure there are TONS of perfectly legal reasons not to want people to track your finances. Many of them are even moral. But obviously many are neither moral nor legal. (The edge case of moral but illegal sure gets people fired up, but it's a vanishing minority of actual use.) So when the regulators come looking for criminals, we unsurprisingly get lots of sound and fury about how there are lots of perfectly valid reasons why good people will want to act in ways that make them look like criminals. Uh huh. Yes, there sure are.

Yeah, I feel like these libraries are all one level lower than what I’m asking for. We need something that makes more assumptions (e.g. “I’m running as a component of some kind of database”) but… makes less decisions? Is more flexible? Idk. This is the hard part.

DataFusion nailed this balance between an embedded query engine and a standalone database system. It brings just the right amount of batteries that it’s not a super generic thing that does nothing useful out of the box, but it doesn’t bring so many that it needs to compete with full database systems.

I believe the maintainers refer to it as “the IR of databases” and I’ve always liked that analogy. That’s what I’d like to see for vector engines.

Maybe what we need as a pre-requisite is the equivalent of arrow/parquet ecosystem for vectors. DataFusion really leverages those standards for interoperability and performance. This also goes a long way toward the architectural decisions you reference — Arrow and Parquet are a solid, “good enough” choice for in-memory and storage formats that are efficient and flexible and well-supported. Is there something similar for vector storage?

Off-Topic: Most stories about politics, or crime, or sports, or celebrities, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.

Politics are politics no matter whether you happen to agree with them or not. If politics are off-topic then so are all those Guardian articles and flagging them is the correct approach.

Mind you, I have my disagreements with this policy since I know nearly everything has been made political. Be that as it may the policy should be applied without bias for this forum to not devolve into yet another Reddit clone.

That is not the case. A non-criminal chargeback maybe, but if you've had your card stolen and chargeback with a merchant for that, they don't hold that against you.

Though, it maybe be more annoying to get your purchase approved because the automated risk system will flag it.

We sell product to people with prior chargebacks with us every single day

I find this part most interesting: "Three participants (2, 7, 8) regained motor control. i.e., converted to AIS C or D, at the 1-month examination. Other three (4, 5, 6) converted to grade C after 3 months. In the present study we observed that, in contrast to the expected baseline conversion of 15%, 75% (6/8) of the participants regained voluntary motor control after polylaminin treatment. If we consider only those participants that reached discharge, the proportion increases to 100% (6/6)."

> Voluntary job switches are just as easy as U.S. citizens.

Then why did my wife's friends that lost their H-1B jobs have to leave America?

American citizens don't face deportation with job loss.

Also, as a US citizen, I'm free to quit my job anytime I want. If I don't like putting up with my job because of some bullshit my employer pulls, I can easily leave. That is absolutely not the case for sponsored workers.

H-1B workers are stressed out and paranoid about their employment. They'll put up with far more, for far longer, with less compensation.

> For e-commerce workloads, the performance benefit of write-back mode isn’t worth the data integrity risk. Our customers depend on transactional consistency, and write-through mode ensures every write operation is safely committed to our replicated Ceph storage before the application considers it complete.

Unless the writer is always overwriting entire files at once blindly (doesn't read-then-write), consistency requires consistency reads AND writes. Even then, potential ordering issues creep in. It would be really interesting to hear how they deal with it.

We shard the data and index on about 6 x n2-standard-96 spot instances so the total cost of indexing the entire deep1b is less than $12. We are working on to make it $6. We separate indexing and query VMs. For queries we use dedicated VMs. USearch numbers look great and are better than ours if you run the query and indexing on the same VM/node. We believe design-wise distributed, task-oriented design is the right way to handle vector search for thousands of tenants with different size datasets. Data ingest is also a separate task for us so Ingest, Index and Query are all handled by different cluster of VMs.

Except I’ve only ever encountered 1 doctor who isn’t in network. I have a 4k max out of pocket for out of network. Even my acupuncturist is in-network.

I’ve never found a doctor who would do anything daily, but if there was a medical need, I’d expect it to be covered.

Where in the world is a facelift covered? No healthcare system covers that. What a silly thing to point out.

If a doctor is willing to rx ozempic I’m sure they’d cover. I already get a glp-1 covered.

Brand name drugs are covered fully.

Yes I have to pay my $500 deductible and co-insurance until I hit my 2k max.

What constraints?

As I understand it, the issue is that the official pathway to hire a permanent foreign worker (PERM status) is very long (18 months+), and most companies don't want to start a process in hopes of hiring someone in a year or more. H1B offers a shortcut, where they can be brought in on a temporary permit, then apply for PERM status. But PERM status requires a bona fide search for American workers; using the H1B shortcut legally would require an awkward job search where you already have an employee in the role, and if an applicant is found the current employee not only loses their job but has to literally leave the country. So instead of getting into that awkward situation, employers are faking the "bona fide search" requirement and trying to hand the green card status directly to the H1B even when Americans are available that could do that job.

That said... there is still the question of why companies choose to go down this road instead of simply hiring Americans. We can speculate about their intentions (cost saving via lower wages, employees willing to work more hours and under worse conditions, racism, etc) but it's unlikely that they're violating federal law just for fun. This is a lot of hoops to jump through and risk to take on without a compelling reason to do so.

> The problem is that sometimes library may need to pin a dependency version.

We on the Cargo team have been working to educate people on the problems with pinning in Cargo.toml instead of relying on Cargo.lock

> Then the library authors may want to use newer language features on their API. Then they simply bump the library mayor version and maintain only that. So an old dependencies will not get updates.

Thankfully, the ecosystem has mostly settled on build requirements not being subject to SemVer and bump Rust versions in compatible releases. There are a few hold outs.

I made my pages static HTML with no images, used a fast server, and BunnyCDN (see profile domain). Ten thousand hits a day from bots costs a penny or something. When I'm using images, I link to image hosting sites. It might get more challenging if I try to squeeze meme images in between every other paragraph to make my sites more beautiful.

Far as Ted's article, the first thing that popped in my head is that most AI crawlers hitting my sites are in big, datacenter cities: Dallas, Dublin, etc. I wonder if I could easily geo-block those cities or redirect them to pages with more checks built-in. I just haven't looked into that on my CDN's or in general in a long time.

They also usually request files from popular, PHP frameworks and othrr things like that. If you don't use PHP, you could autoban on the first request for a PHP page. Likewise for anything else you don't need.

Of the two, looking for .php is probably lightening quick with low, CPU/RAM utilization in comparison.

Yup. You see this when any org hires a top exec externally: they bring their trusted lieutenants/golf buddies and push out the old brass, and then this repeats down the chain when these hires do the same.

Unsurprisingly, an Indian exec's trusted lieutenants and golf buddies will also be Indian, likely from the same university, caste, etc. They will not be hiring random people just because they happen to be Indian; if anything, there's been plenty of lawsuits over Indians of the "wrong" caste, language group etc getting pushed out.

These are great points. The #1 concern I have as a parent and that I hear from other parents is that AI tools will do what technology has been doing for the last 20 years: replace human connection. That is exactly what we are trying to avoid but in a way that still gets kids access to knowledge and information that could make their lives better.

That's great that you had the opportunity to ask your parents those questions instead of seeking them out with technology. There are a lot of questions that could help kids lead better lives that many parents don't have answers to. Not necessarily philosophical ones, but practical ones about how to cook, identify insects, you name it, about the physical world. We want to fill that need without replacing any of the parental or family connection.

I don't think that a cleverly designed product can make that decision though. I think families need to be making the decision about what their relationship with tech should be. Ideally we would be a tool for families that have made the decision to not overly rely on tech. We will ponder more on that point. Thank you for the thoughtful input.

> you found that your fellow countrymen are much more likely to follow your leadership style than any other group of different cultural background

Two points.

First: a good, seasoned manager adapts their leadership style to their employees. So the premise is a bit backwards.

But second, let's suppose we use something more valid like "ability to follow instructions". And suppose there are real differences in groups. You still don't stereotype on groups, because lower-performing groups still have high-performing members. So you have your interview examine the actual skill you need on an individual basis. You don't make assumptions based on group membership.

Now, for practical reasons candidates need to be reduced to a reasonable number to interview. That should be done according to personal accomplishments and experience, not groups.

The college you went to is tricky. Only hiring from a select group is not very defensible mainly because it's a bad signal. It reflects mostly your high school test scores and grades, which was years ago. On the other hand, some colleges teach in certain departments better or worse, your grades might matter and depend on the college, etc. So you need to calibrate for a bunch of achievement-based signals where the college name can matter, rather than whitelist only certain colleges.

From the GP: > I have never heard of an insurance policy in the US that allows you to consume as much, and whatever type of healthcare that you want. Quite the opposite is most people's experience. You have to justify any visit to a specialist before going, you don't get to choose the specialist, many times the insurer will simply deny a payment request for care already received. On many plans, you have to spend 5 figures per year before they will even cover anything.

These do not apply to me. I cannot be the only one. In fact when I was a 2 person startup things weren’t so terribly different from my current situation as well. No need to accuse me of classism when I’m simply refuting the premise with my own data and lived experience.

Many people are only casually interested in something, so they learn less quickly. Or they are just learning for the first time. It's not actually particularly incredible that there are people who don't know this.

VLQ/LEB128 are a bit better than the EBML's variable size integers. You test the MSB in the byte - `0` means it's the end of a sequence and the next byte is a new sequence. If the MSB is `1`, to find the start of the sequence you walk back until you find the first zero MSB at the end of the previous sequence (or the start of the stream). There are efficient SIMD-optimized implementations of this.

The difference between VLQ and LEB128 is endianness, basically whether the zero MSB is the start or end of a sequence.

0xxxxxxx - ASCII 1xxxxxxx 0xxxxxxx - U+0080 .. U+3FFF 1xxxxxxx 1xxxxxxx 0xxxxxxx - U+4000 .. U+10FFFD 0xxxxxxx - ASCII 0xxxxxxx 1xxxxxxx - U+0080 .. U+3FFF 0xxxxxxx 1xxxxxxx 1xxxxxxx - U+4000 .. U+10FFFD

It's not self-synchronizing like UTF-8, but it's more compact - any unicode codepoint can fit into 3 bytes (which can encode up to 0x1FFFFF), and ASCII characters remain 1 byte. Can grow to arbitrary sizes. It has a fixed overhead of 1/8, whereas UTF-8 only has overhead of 1/8 for ASCII and 1/3 thereafter. Could be useful compressing the size of code that uses non-ASCII, since most of the mathematical symbols/arrows are < U+3FFF. Also languages like Japanese, since Katakana and Hiragana are also < U+3FFF, and could be encoded in 2 bytes rather than 3.
by nostrademons | 2025-09-12 23:56:39+00:00
Sure, but for something like that whatever constructs the view can use an opaque index type like Animats suggested, which under the hood is probably a byte index. The slice itself is kinda the opaque index, and then it can just have privileged access to some kind of unsafe_byteIndex accessor.

There are a variety of reasons why unsafe byte indexing is needed anyway (zero-copy?), it just shouldn’t be the default tool that application programmers reach for.

I appreciate this concern. I definitely don't want another layer of tech between myself and my kids. We will reconsider our marketing. I think the issue though is that even though kids use Google, Google doesn't market for kids, so they can show explicit stuff even with safe search on. So we're in a situation where there is only adult websites that kids use and worthless entertainment garbage that is marketed to kids.

Maybe you're right though. Maybe trying to create something that just provides information without drawing users in and replacing human connection is a losing game because of the marketing challenges.

I have a view of a brick wall, that has a setback, so the left part of the wall is closer than the part to the right. From a certain distance, the setback has six vertical courses aligning with the mortar and on the closer face of the wall every five courses. I wonder how perceptive our visual areas might be with respect to pixels when I see the shattered shadows of LED panel parking lot lights (32 individual point sources) or the strobe at night of headlights. Still, I would like a curved display. Maybe a Las Vegas Eyeball.

I use the em dash as appropriate, similar to semicolons and their ilk.

I don't think use of an em dash is indicative in itself of AI assistance, but rather, the change to using them. Did this person all of a sudden start using them? There are also other things to look at, like how certain bullet point lists have emphasis (for key phrases, being bold, when previously the author didn't do so, stylistically).

I write a lot (as a PM) - I've taken to using MacWhisper, which does local AI dictation, but also (at my configuration) sends it to a ChatGPT prompt first:

"You are a professional proofreader and editor. Your task is to refine and polish the given transcript as follows:

1. Correct any spelling errors.

2. Fix grammatical mistakes.

3. Improve punctuation where necessary.

4. Ensure consistent formatting.

5. Clarify ambiguous phrasing without changing the meaning.

6. If a sentence or paragraph is overly verbose and has more than negligible redundancy, lightly edit for brevity.

7. If the transcript contains a question, edit it for clarity but do not provide an answer.

Please return only the cleaned-up version of the transcript. Do not add any explanations or comments about your edits."

This is great. I get the benefits of pretty accurate transcription while getting a first pass at copyediting almost in real time. It did require me to make some tweaks to my dictation process (allowing it to "chew" on larger chunks to give better context to its editing), but it works very well.

I used to be against the real ID moves of early social media platforms, and now I wonder. How would information spread if social media users on X, for example, were clearly identified as 1 to 1 associated with a named person? Sore they might spread something, but unless that guy in Russia has an American ID, then he's not posting.

The current, put as many bots as you want on, approach is pure war.

I don't feel like Apple abuses my intellect. It's well known that Apple doesn't really care about people who want things that they don't offer, they market their devices to owners of their other devices. There are more expensive devices out there but none of them deliver the same value that Apple's devices do. They use standard methods and they have standard functionality and that's fine but if you want Apple then you buy Apple. Everyone is talking as if users are forced to buy and use Apple devices. The fact is that if you want a pebble or a garmin watch then you can just buy an Android phone and use that as the center of your tech and be happy with your non-apple devices. Why would someone want a Garmin watch that's compatible with their iphone? What possible real, non theoretical, reason is there to have one over an Apple watch? My wife had one and it's features were fairly pedestrian. There is nothing it did better than an Apple watch and that wouldn't have changed if it was able to work with Apple's proprietary technology. The existence of a comfortable walled garden alongside an open forest is not impossible by any stretch.

I don't disagree at all with you, but it does pain me a little bit to see a phone referred to as an appliance. Phones nowadays are plenty capable general purpose computers if they aren't intentionally handicapped by the manufacturers, and the manufacturers certainly do think of them as appliances and treat them as such, but I wish that collectively we would reject that and insist on not artificially hobbling their capabilities

For some visa types, companies are obligated to prove that they advertised the position to American citizens. Failed, hence they needed the foreigner.

This is a huge dealbreaker for campus hires, and specifically masters/PhDs who are, well, by definition, specialized in their field and hence very rare.

So you recruit at her graduation the girl who has done groundbreaking research in deep neural nets and is the key to one of your big projects. She happens to be non-American (because the majority of graduates are non-Americans).

Now what? You know that there is nobody else on the planet that has done this research, yet you have to start recruiting for this position for Americans.

What is the incentive you have as a company to pour a ton of resources on this effort? Recruiting is very expensive. Time is also very expensive when you are at the forefront of innovation.
