Yeah at this point the goal is to see how to maximize for inference. For training it is impossible from the get go to compete with the frontier labs anyway. Im trying to calculate (even amortized over 2 years) the daily cost of running the equivalent rig that can get close to a single claude agent performance. (without needing a 6-digit gpu).

This is exactly the challenge. When embedding were first popularized in word to vec they were interpretable because the word2vec model was revealed to be a batched matrix factorization [1].

LLM embedding are so abstract and far removed from a human interpretable or statistical corollary that even as the embeddings contain more information, that information becomes less accessible to humans.

People aren't getting that it was two characters that need to be added, not two bytes to make a short into an int. COBOL uses a fixed width character format for all data (yes even for COMP). If you want a four digit number, then you have to use 4 character positions. Ten digits? Then ten characters.

These field sizes have to hard coded into all parts of the COBOL program including data access, UI screens, batch jobs, intermediate files, and data transfer files.

On the other hand - when Israel struck the parking lot of that hospital a couple of weeks ago everyone was so confident that the IDF was lying when they said that there was a command bunker just underneath the entrance of the hospital.

Not only did that end up being completely true, but the IDF killed Muhammad Sinwar in that strike.

"international law" is, i don't know how to say this quite right, largely for show

when both sides seem to be willing and eager to order, participate in, and cheer for atrocities from leadership to the common people... I don't want to take ideological sides or tally up crimes to decide who to root for in millennia old conflict mostly over a single city

it's a terrible shame for the people who want to live together in peace, clearly there are not enough of them

This is truly a great idea! And it seems very feasible ＞▽＜ If this system existed, HR departments would definitely take advantage of it! It could increase the chances of discovering hidden talents who may not be good at sales. Your idea is a rare combination of profitability and contribution, making it a valuable asset in today’s evaluation system.

> In the US you have to be worried about taking an ambulance or visiting the ER may cost you thousands for nothing.

No you don't. For one, if you are insured that is not a possibility. And 100% of the people I know who are not insured save more money than insurance would cost them given their incomes are higher and taxes lower than Germany. They choose to accept the risk because they are relatively young and healthy. All of them could cut down on luxuries and pay for insurance if they wanted to.

I once took an ambulance to the wrong ER, not understanding that I had to go to one that took my insurance. When the hospital found out my insurance wasn't going to pay, they lowered the bill by 90% and it was completely manageable.

Meanwhile in Canada I have family members that have to wait nerve-racking months for life-saving procedures or even imaging. In the US, I've had a few MRIs the same week the nurse practitioner ordered them for things that were absolutely not urgent.

I'm not in frontend mainly, but this article, and another short I watched about how useEffect is almost always wrong makes me feel uneasy about React. It's insidiously complex.

A bunch of `useCallbacks` are rendered ineffective because the top of the chain wasn't properly computed. And the fix isn't `useCallback`, its to rearchitect the tree. This feels wrong - either the API, the framework, or the language isn't powerful enough to ensure that someone does the right and performant thing. It seems like the new React Compiler tries to fix this - but I'm surprised React Compiler is a thing that needs to be built.
Ask HN: Has your opinion on AI changed over the past year?

As in, were you originally optimistic about AI, but are now pessimistic, or were once pessimistic but are now optimistic? Did you originally see it as a huge boon to your work, but now find it a hinderance, or were you once dismissive of it, but now find it indispensible?

Just curious who has changed their mind/outlook and what precipitated the change.

Well, not the entire week, however much of it is left. You said you probably won't hit it -- if you do, it's very likely to be in the last 36 hours (20% of a week) then, right? And you can pay for API usage anyway if you want.

I like the spirit but wouldn't this run afoul of one or two laws? Identity fraud or some such?

I'm not in the UK, so I don't have any idea about their laws, but I'd be shocked to find this was above board. Your FAQ claims it's a parody site and claims "The ID number isn't valid and you can't use the card for anything real." but you've just confirmed here it can indeed be used for real things (discord, reddit).

Your domain registration is UK-based, so, be careful!

That would probably require some serious infrastructure to set up secure food distribution points, which I'm assuming isn't easy because the locations have to change as the evacuation areas also constantly changimg. From the video it looks like they only have some berms and small fences so I'd imagine it's a dangerous security situation.

Although having way more food/distribution points might help reduce the violent mobs.

It makes me sad that devs start relying on proprietary online services to be able to work. We have been lucky enough to have FOSS tools to do everything and not to have to rely on any specific service or company to work and some of us are deciding to become like Monsanto-addicted farmers who forgot how to do their jobs without something they have to pay every month.

I use Garmin so it may be different, but if Wahoo is like Garmin, you should be able to import a GPX file into their app and then tell it to sync to the computer, without needing Komoot to do the syncing. A bit more work but then you don't rely on Komoot directly to handle this for you.

Okay, let's roll with the idea that Epstein was somehow involved with (or working for) a country or its intelligence service - which is the commonest conspiracy theory I've read.

So sure, that's probably blackmail and subversion (via kompromat on prominent politicians or business people) in favour of that country's interests, but again that's insolated and self-interested (i.e. in the interests of the particlar country in question). But it's not centralised 'divide and conquer the proletariat' in favour of the (ultra-)bourgeois, which was my original point.

I'm not saying that such things don't exist; I'm just arguing they're not as centralised and targeted at creating divides and unrest amongst the people as the original post suggests, as usually that's not a tactic that results in a beneficial outcome for the group involved. Epstein's putative handlers weren't going "nah, forget infiltrating the mil-tech sector in your country; what we're really interested in is a few headlines about immigration in the UK".

Hardware GPU encoders refer to dedicated ASIC engines, separate from the main shader cores. So they run in parallel and there is no performance penalty for using both simultaneously, besides increased power consumption.

Generally, you're right that these hardware blocks favor latency. One example of this is motion estimation (one of the most expensive operations during encoding). The NVENC engine on NVidia GPUs will only use fairly basic detection loops, but can optionally be fed motion hints from an external source. I know that NVidia has a CUDA-based motion estimator (called CEA) for this purpose. On recent GPUs there is also the optical flow engine (another separate block) which might be able to do higher quality detection.

Are there any examples where someone got "de-banked" or "de-payment-processored" because of misogynistic (but legal) content?

Two different people might both want $100 from you, but that isn't enough for an equivalence: I'm sure you'll agree there's an enormous practical difference between the one that does/doesn't think "knife stabs" are a valid tactic. Or even just between two where only one owns a knife.

> One can be deeply sympathetic to the millenia-long suffering of the Jewish people and even want them to have a homeland, and yet believe that Israelis are largely unconcerned with the welfare of Palestinian civilians

And then extend that to believing Hamas are monsters, that whenever Palestine has--in modern times--had any power or leverage, it has used it to be a pest to its neighbors, and yet still believe that those people don't deserve to face starvation, bombing, economic ruin and forced displacement.

Oh wait, except that's not true.

Retired Maj Gen Yoav Har-Even described how the IDF's drone operators mistook an aid worker carrying a bag for a gunman, and then targeted one of the World Central Kitchen vehicles with a missile.

The IDF then described how two people escaped that vehicle and got into a second car, which was hit by another missile from a drone.

The military confirmed that there were survivors from the second explosion, who managed to get into the third vehicle - which was then also hit by a missile.

By the end, all the aid workers were dead.

https://www.bbc.com/news/world-middle-east-68742572

Agreed that bombing the 1st vehicle of aid workers was a mistake. Then bombing the 2nd vehicle was a mistake, and the 3rd vehicle bombing was also a mistake.

That would be one reason things won't get better for his voters. At which point they'll look for more extreme politicians. It will get worse.

Hell, it already has gotten worse in both France and Germany compared to the US. Imho Macron is more or less the same kind of politician as Trump (rich, and in it to make the rich richer), just a very different person (for one thing he's easily got 10x Trump's IQ, 10x Trump's looks, and doesn't look like an ancient golden retriever that got demummified for a presidential term). Obviously this guy failed to improve France's economic prospects, and every election cycle the actual Nazis, led by Le Pen, gain 5% extra of the vote. Germany differs a lot in the details, but something similar is happening.

The situation in (some parts of) Europe is like if you're hoping for 3rd Trump term, because Steve Bannon became a presidential candidate that polls over 50%. When Trump has just made immigration policy stricter in desperation, because even Trump realizes what a disaster that would be.

Uh, that's the classic security through obscurity (STO) defense on the face of it but it sounds like a cop-out to not open source it. If one desires not to open something that's fine, but if they misrepresented the reason for doing so would be bullshit.

This is a very common fallacy repeated by people who are either interested in supporting homeschooling, or haven't thought much about the subject.

The most telling stats is that the percentage of homeschooling parents increases, specially in religious communities but the test takers in homeschooled scenarios almost always come from higher educated urban families.

There is a large case of selectin bias, in a public school every kid takes an SAT test. For homeschooled kids, the kid of two doctors who was homeschooled and aces tests for breakfast he takes teh SAT and smokes any underfunded public school near him (although he probably scores average or below prep schools that cost arguably less than his homeschooling, with additional socialisation benefits etc). Meanwhile the hyper religious family wanting their daughter to marry at 16 is not letting that barely literate girl take her SATs.

The two groups in favour of home schooling are hyper capitalistists who think the disruption of public schooling + their advantage will make their kid unstopable, and the niche fringe believes, usually religious who are scared of interacting with mainstream institutions for fear of disrupting their reality. Both are problematic, anti social and harmful groups and their over representation in goverment and media is largely a sympton of the inability of liberal institutions to fight against illiberal threats.

It's also possible that your machine lets off some elecromagnetic noise you can detect directly.

The other thing you could try is put some sort of a microphone / vibration on it, then train a small NN on the waveform to distinguish between the washer and dryer.

it's literally just the MPs name. It's a fake DoB (because their DoB's aren't public knowledge anymore) all the numbers and such are nonsense, the images wouldn't fool a human for one second. The AI tools don't let you generate an ID for any real human being (because that sounds like all sorts of fraud) so you can't upload a picture of the MP or anything like that - so I just let the model fill in whatever face it thinks is appropriate for the given name.

The main reason IMO to block rooting is to stop resellers selling phones with preinstalled malware. If the phone has two Amazon/Aliexpress sellers, you're going to pick the cheaper one right? With who-knows-what alterations? It's a really prevalent problem and most people are not going to notice the "insecure" warning at bootup.

Hind Rajab being used as bait to murder aid workers was kind of a tell also.

Or when they bombed all the hospitals [0], or targeted pediatricians and oncologists, and their families [1] for assassination.

Or leaving preemie babies to rot and be eaten by wild dogs at Al Nasr [2].

Or when they dropped over 6 Hiroshimas worth of explosives [3] onto an area roughly equal to a 12 x 12 mile square, populated with over a million children - in Biden's term alone.

There's a lot more. Suffice to say that anyone paying attention has known that the US, Israel, Germany, England and more have been propping up a genocide for quite some time now.

Honestly, wonder if that might work. There were not that many folks involved in the original push against on steam and others. The game publishers really don't want this. The gamers don't. I don't think visa wants the sort of legislation that will be pushed for next if they play that role. The 'think of the children' play .. not sure that is going to work here. Way to many groups have been on the 'wrong side' of a cultural normal to want visa to be the judge here.

Regarding the second point, did Starlink choose not to do anything, or did it not get in front of the right people? Tagging Elon in an X post and expecting a response isn’t realistic as the only form of contact. I assume he’s tagged so much it isn’t possible to read them all, let alone reply to them all. Wired reaching out for comment is the press, where I assume “no comment” is the typical response to everything, as it is with most companies.

>The only way you'd ever get found out is if the affected MP was lying to the public and the identity documents do indeed get retained...

I'm more talking about the developer of the site rather than the users. And the developer could potentially be found out if they posted it on a popular hacking website and used a known alias and registered the domain in the UK.

But, if they're comfortable, all the more power to them. As I said, I do really like the spirit of the site.

Ahh, this is such a pet peeve of mine. I hate how it leaks. A thing I often also encounter in this vein is when you write a useEffect, but the linter forces you to declare everything in the dependency array. I only want the effect to trigger when x changes, and then call function y. But I have to declare y as well, but then if y isn't memoed it will trigger every render. But I don't want that, and I might not even have full control of function y, coming from somewhere else. I could usecallback around it myself first, but that just moves the problem, as I need to maintain the correct closure, or there will be subtle bugs.

A second but unrelated grief with hooks is when you get async updates happening in between renderers where you want to update some state and then do some logic. Let's say I'm waiting for 2 requests to finish. They both should update a value in my state. However, to not lose an update if both happens at the same time, I need to do the setState with a callback to see the latest value. But then, what if I want to trigger something when that new calculated state value is z? I can't do that imperatively inside the callback, and outside it I can't see the new value and don't know that I now should do something additional. I have to do it in a useEffect, but that decouples it too much, the logic belongs where I want to put it, in my state hook. Not in some useeffect wherever. The other option is to misuse refs to also maintain a current state there in addition to the useState. So always use the ref, but set the state in the end to trigger a re render.

Hooks are so unelegant for real problems. I hate how they force your hand to write spaghetti.
Show HN: ReDB – Distributed data mesh for seamless DB replication and access
by tommihip | 2025-07-28 22:09:40+00:00
We just open-sourced reDB: a distributed, policy-driven data mesh that provides real-time access, replication, and migration across databases — including relational, NoSQL, graph, vector, and more.

It’s designed for AI systems, developers, and ops teams working in complex, multi-database environments.

Highlights: - Unified schema model across database types - Built-in schema version control - Zero-downtime migration and replication - Quantum-safe encryption and data obfuscation - AI agent integration via Model Context Protocol (MCP)

To expand, SQLx isn't an ORM or query builder, what it does is allow you to write raw SQL with compile-time guarantees of type safety. It does this by connecting to a dev database at compile time & uses SQL's introspection features (specifically, by preparing a statement[1]) to analyze your queries. (It can also cache this information to check without a database available, and has a basic migration facility.)

Some quick prompting seems to say a G force of somewhere between 16-160 billion Gs, for a CPU-equivalent object getting hit by a solid object moving at 3I's escape velocity. Compared to a "typical" artillery shell of 10-15 thousand Gs. Not sure you're manufacturing anything that could survive 6-7 orders of magnitude more Gs than an artillery shell.

Of course the G-load would lessen based on how much you sped up to match its speed beforehand, but still, I think you'd need to be pretty much sped up to near the same speed as it before you could remotely possibly survive the impact.

Estragon was fully serious in his answer to Vladimir, wrong as it was nonetheless. Vladimir was not at first convinced of the wrongness of the answer, and they spent a fair bit of time debating about how to hang themselves and who should go first until they decided it was a wrong answer.

But the original statement was simple: "There are more ways to be wrong than there are to be right." You took issue with this, but if you're willing to grant that the set of wrongness is infinite, we're one step away from a debating proof (pumps fist: internet points!). If you'll concede that the ways to be right in answer to the question are finite, which I'd assert even in the innovative space, they are, then the statement holds.

At any rate, thank you for the discussion.

I’m super happy Google’s login with my name, appears on PornHub, especially since I’m using a separate browser, Firefox mobile, for this only, never used it for anything else, never logged in. Luckily Firefox mobile gives websites access to something on my phone about my identity. But I’m happy it does this.

Because it exposes how much websites know about us. It’s like Facebook showing face recognition in 2015. It’s creepy but it reminds you constantly how creepy it is.

(Disclosure: I work for Microsoft) I run automated red-teaming on my RAG samples through the azure-ai-evaluation SDK, which uses an adversarial LLM (an LLM without the guardrails) plus the pyrit package to come up with horrible questions to ask your app and then transform them (base64, ceaser cipher, urlencode, etc), to see how the app will respond. It's really interesting to see the results, and I agree that red-teaming generally can be a good use of LLMs.

Even if you think a lot of the content captured by the ban should be banned, I don't think age restriction mechanisms should be put on it. Talks around sexuality, the mere mention of certain crimes and unrest are being banned by social media companies, all because of this act. Companies seem to be acting out of caution.

I simply don't want to be forced to provide my ID / face to be able to read or access politically important news on social media. Some people would be happier if the bill was limited to only pornography: they likely don't think it has a major effect on UK politics.
