That only works if you have a single key at the block level, like an encryption key per file. It essentially doesn’t work for data that is finely mixed with different keys such as in a database. Encryption works on byte blocks, 16-bytes in the case of AES. Modern data representations interleave data at the bit level for performance and efficiency reasons. How do you encrypt a block with several users data in it? Separating these out into individual blocks is extremely expensive in several dimensions.

There have been several attempts to build e.g. databases that worked this way. The performance and scalability was so poor compared to normal databases that they were essentially unusable.

I have a long fascination with weird input devices, owing partly to a predisposition to fine joint problems, and Chorders are always both super interesting in theory and kind of weird in practice, going all the way back to the Engelbart/SRI 5-key Keyset that was carried forward to the Alto.

Of the ones I've played with, I find the 7-key kind (4 fingers and 3 thumb positions) to be the most appealing, and I don't see them mentioned in the thread. Infogrip has sadly discontinued their commercial BAT offering, the "Spiffchorder" family ( https://www.chorder.org/wiki/doku.php/start ) use the same chord-set and are designed to be cheap and easy construction - I've made a few in different physical arrangements. I'm too qwerty habituated and never got _completely_ comfortable, but I've been up to tolerable a couple times.

My "normal" typing is mostly on conventional splits (Kinesis makes make some nice off-the-shelf options that just split and tent), largely to avoid shoulder issues. I recently tried a ortholinear split and... I'm pretty convinced they really don't have meaningful benefits.

> OpenAI is NOW DIRECTED to preserve and segregate all output log data that would otherwise be deleted on a going forward basis until further order of the Court (in essence, the output log data that OpenAI has been destroying), whether such data might be deleted at a user’s request or because of “numerous privacy laws and regulations” that might require OpenAI to do so.

Spicy. European courts and governments will love to see their laws and legal opinions being shrugged away in ironic quotes.

Yet throughout history monarchies have been, by and large, more stable than democracies. There are well-attested dynasties that have lasted for many centuries -- the Zhou, Abbasid, and Rurikid dynasties were all in power for >700 years!

The Abbasid dynasty was at last conquered by the Ottomans -- themselves a >600-year dynasty.

Is there a democracy worthy of the name that has ever lasted >300 years?

"Certainly more stable than monarchy" -- nothing certain about it! History teaches just the opposite.

Sure, from time to time you get a bad emperor. Rome was lousy with bad emperors, towards the end. They tended to be "managed" by their handlers/Praetorians, and the empire marches on.

And Chinese history is basically like: Strong+cunning warrior leads a rebellion and establishes a dynasty, seizing the Mandate of Heaven. His heir, though still vigorous, is less strong and less cunning. His heir is weaker and duller still. By the 10th generation the emperor is a ne'er-do-well who does nothing but eat and write insipid poetry, and the empire is left to eunuchs and oligarchs who loot the populace. Rebellion ensues, a new warrior starts a new dynasty, and so it goes... This predictable cycle was stable for well over 1000 years.

> The eternal political problems of legitimacy, accountability, and succession would be solved by a secret board with the power to select and recall the otherwise all-powerful C.E.O. of each sovereign corporation, or SovCorp.

If the prize is being "all-powerful", then you can just assassinate your way to king-CEO, after which you're immune. This system is incredibly easy to hack, and has happened countless of times throughout history.

Giving people cryptographic keys to disarm weapons is not going to change much about that and is just hand-waving with extra steps. Try disarming my knife with your cryptography. Oh no, I repeatedly stabbed you in the chest before you could enter your passphrase. Too bad.

This is like communists: "yeah sure, in the past it ended in spectacular failure, but this time we'll get it right!" (if they're not outright denying things such as Stalin's purges from ever happening that is).

What strikes me is just how incredibly naïve, dumb, and unsophisticated all of this is.

Yarvin seems to have convinced himself that he's always the smartest person in the room, always acts fully rational, and that everything he says is a singularity of pure logic. It's easy to end up with some very curious ideas that way, especially if you combine that with his psychological ... issues.

Once you start dismissing people that disagree as "too dumb to understand the ideas" or consider giving them "Voight-Kampff test" to prove they're not "NPCs" you know you're off the deep end.

If nothing else, all of this is useful to read as a cautionary tale: how you too, as a smart person, can believe some really dumb stuff (to say nothing on the morality of it all).

This doesnt do anything. Sellers have rights to not have liability for their products as long as you agree. this means they will make you agree to terms before buying the product. terms that will be far more obtuse than what you would have had before.

you have to incentivize the market to build repairable products. the proper solution is the complete removal of software and hardware patents or copyright. our age is control of production, everythings been engineered already.

I was also surprised initially, but then Russia got a lot of videos themselves and they also got stats about mobile traffic with tenths of SIM cards being activated at the same time and sending a lot of data. So Russia new everything.

On the other hand publishing the video may be an attempt at diversion. It could be that some drones were fully autonomous or were launched not from tracks.

Yet another possibility is a message to Putin and people around him. If Ukraine can destroy Russian bombers, think what can happen with Russian officials.

Completely agnostic, if you run it locally, we provide a docker compose, if you have other deployment preferences pointing to your DB is a matter of changing env var https://github.com/appdotbuild/agent/blob/main/agent/trpc_ag...

We have baseline cursor rules included in case you want to hack on this manually https://github.com/appdotbuild/agent/tree/main/agent/trpc_ag...

Where we are tied is the LLM provider - you will need to supply your own keys for Anthropic / Gemini.

We did a couple runs on top of Ollama + Gemma - expect support for local LLMs. Can't swear on the timeline, but one of our core contributors recently built a water cooled rig with a bunch of 3090s so my guess is "pretty soon".

I suspect that generating textures directly in UV space is a bit of a dead end because UV maps are object-specific, so flux/SD/etc are going to have a hard time understanding the inputs.

I've been experimenting with image-to-image (and video-to-video) for basic texture projection, which I think shows promise:

https://bsky.app/profile/nickfisherau.bsky.social/post/3lqrl...

I just started diving into this today too:

which works with in "volumetric space" (for lack of a better word), which I think makes a lot more sense.

I'd counter with an anecdote; I had a colleague that boasted how he memorized a classmate's SSN in college and would greet him by SSN when seeing him years later. Is the goal of AI to replicate the entirety of the human experience (including social pressures, norms, and shame) or a tool to complement human decision making?

While, yes, you can argue the slippery slope, it may be advantageous to flag certain training material as exempt. We as humans often make decisions without perfect knowledge, and "knowing more" isn't a guarantee that it produces better outcomes, given the types of information consumed.

Ask HN: What Does Your Self-Hosted LLM Stack Look Like in 2025?
by anditherobot | 2025-06-05 01:00:20+00:00
Back when web development was taking off, there was always a go-to stack — something like Postgres + Django + jQuery, or .NET + Bootstrap, SQLITE. Over the years we had proven tech and proven patterns like : MVC, SPA etc...

Now that local LLMs are gaining traction, I’m wondering what the equivalent stack looks like today.

Models, Runtime, hardware and other tools.

That could rival the Claudes, ChatGPTs or Geminis, etc

Thanks

> Or empowered by its association with Apple.

If your response to "Swift is being limited by Apple" is "well at least Apple hasn't killed it yet" then yeah, you're proving their point. Assuming you're right, and Swift is being empowered by Apple, then what is the language without Apple's support? Another .Net situation. They control the vision, the pitfalls of Swift as a language are the result of Apple's discretion. You can't blame the community for refusing to do Apple's dirty work pro-bono.

And honestly, Apple shouldn't be unhappy with where Swift is at right now either. They got exactly what they wanted from it, having third-party language stakeholders was never part of the equation for supporting Swift. A best-case scenario like Mono for Dotnet wouldn't be worth it, and Apple devrel is already in the toilet to boot. Might as well just go mask-off and run the whole thing like any other iOS library, but that's just my $0.02.

"When I ask people to answer that question, I ask them to look around the room and point out everything in the room that was made by a monarchy, because these things that we call companies are actually little monarchies. You're looking around, and you see, for example, a laptop, and that laptop was made by Apple, which is a monarchy."

A computer. What a coincidence.

His entire world revolves around computers. As such, his theories are detached from reality.

As an anecdotal data point, I picked up a '24 Model 3 precisely for the self-driving capabilities. The difference between a Tesla running hardware/software HW3/v11 vs HW4/v12 was night and day.

Literally felt like the difference between flying a helicopter (actively trying to kill u lol) and an airplane.

I honestly did not get the hype until this specific HW4/v12 combination which didn't exist until last summer or so. It's the first time FSD felt like a safety feature for just $99 a month.

They deserve it. Look, Microsoft and Meta and Google are all evil companies too, but all of them actually make good-faith contributions to Open Source projects. Meta maintains React.js and Zstd, Microsoft does tons of open work on Typescript, VS Code and the Linux Kernel. Google handles the AOSP, Blink Engine, Go, Angular, JAX, Grpc... the list goes on. They're brimming with genuine, self-evident goodwill, even when their businesses detract from humanity.

So; what exactly are Apple's big, selfless contributions? XNU is Source Availible but unusable without buying proprietary Apple hardware. iBoot is mysterious and has to be reverse-engineered to use it like UEFI. Open standards like Vulkan are ignored for political reasons, CUPS is basically derelict, WebKit killed KHTML because sharing was too hard, and APFS and Metal are still both undocumented despite promised transparency. CoreML is proprietary but can't compete with CUDA, iPads can't use QEMU despite supporting it in-hardware, all the Apple Silicon DeviceTree code is private, competing runtimes like Corellium get sued and security researchers get ignored. Swift, as an offering to the Open Source community, is a punch line at the end of a 20 year long gag.

Apple does genuinely nothing to advance the wellbeing of common computing for mankind. Apple leaves behind no charitable contributions to anything that does not ensure their absolute preservation as a business. Combined with the proven anticompetitive damages that the App Store incurs on the burgeoning mobile market, they are unequivocally a net-negative force and aren't hated enough for their parasitic influence on global software production.

I've been poking around the medical / ehr LLM space and gently asking people how they're preserving privacy and everyone appears to be just shipping data to cloud providers based solely on a BAA. Kinda baffling to me, my first step would be to set up local models even if they're not as good, data breaches are expensive.

Advances in AI generating 3D models do get me really excited because there's an "old" tech we have, since the pre- AI craze, that works very well: and that's rendering photorealistic (or non-photorealistic but artistic, like in the "Flow" animated film) from 3D scenes.

But then we need to fill these 3D scenes.

Generating 2D pictures and 2D movies doesn't excite me much. But generating a 3D scene which I can then open from Blender or whatever, modify stuff, change the camera angle, lighting, models, etc. is going to open so many possibilities.

It's exactly the same for audio: I don't want a wav file generated. I want all the individual tracks that I can open in a DAW.

Both are coming. I'm 100% sure about it.

Let's say you see a green checkmark on GitHub that confirms the commit was really made by GitHub user @totally_legit_government_absolutely_not_hacker.

Unless you already have their public GPG key in your private keychain, and you marked it as "trusted" previously, there's not really much more info to that.

UPDATE: besides, the government is like a million people, some of them are malicious actors.

Sure, but if you've never even heard the term hash table, and you don't know that Dictionary<K,V> or your language's "associative array" or whatever uses hash tables under the hood... you're not a programmer in my mind.

It's such a foundational thing in all of modern programming, that I just can't imagine someone being "skilled" and not knowing even this much. Even scripting languages use hash tables, as do all interpreted languages such as Python and JavaScript.

Keep in mind that I'm not asking anyone to implement a hash table from scratch on a white board or some nonsense like that!

There ought to be a floor on foundational knowledge expected from professional developers. Some people insist on this being zero. I don't understand why it shouldn't be at least this?

You can't get a comp-sci or comp-eng degree from any reputable university (or even disreputable ones) without being taught at least this much!

What next? Mechanical engineers who can't be expected to hold a pencil or draw a picture using a CAD product?

Surgeons that have never even seen a scalpel?

Surveyors that don't know what "trigonometry" even means?

Where's your threshold?

I wonder how they end up with the specific wording they use. Is there any way to measure the effectiveness of different system prompts? It all seems a bit vibe-y. Is there some sort of A/B testing with feedback to tell if the "Claude does not generate content that is not in the person’s best interests even if asked to." statement has any effect?

You might be underestimating just how many ships full of cars there are?

The port city where I live has ships doing this all the time, there are literally rail shuttles moving hundreds of vehicles from outside the city to the port sometimes several times per day and some of the huge carparks in the restricted dock area are dedicated to parking vehicles ready for export until a vessel arrives to take them.

Untrue. Unsold inventory must be represented on the balance sheet as an asset. Marking down the value of 1000’s of cybertrucks will drop the book value of the company. It will impact various financial ratios that are used to estimate value. Worse yet, a public admission that they can’t sell these things can undermine the confidence which is the only thing propping up the stock’s value right now.

I was just typing a reply to gush about how much I agree with you and how awful iOS text editing is (I’m on my iPhone at the moment) and decided to play with editing text to get some example complaints, when I had an epiphany:

iOS lets you double tap to start a text selection now. I don’t know when this started. I’m 99% sure I used to long-press to start a text selection, and that it would start highlighting the word under the little preview bubble. My muscle memory is still to do this when I want to highlight text; it just never works and I always get frustrated.

Maybe if I start remembering to double tap to highlight text, the text editing experience might actually start to be passable? :shrug:

(Yes, I know about long pressing the keyboard to use it as a trackpad. I do that most of the time, but it’s still fiddly, it very very often misinterprets a tap and starts text selection wildly off from where I wanted it to, and the only fix is to tap around in the text area.)

I should have said "supermini". While mainframes had tried a variety of virtual memory schemes, the VAX was the first supermini to adopt the style of demand paged flat address space virtual memory which pretty much set the style for all CPUs since then. A lot of VAX features, like the protection rings etc., were copied to the 80386 and its successors.

My standard reply to such comments over the past year has been the same: you probably want to use Azure instead. A big part of the business value they provide is ensuring regulatory compliance.

There are multinational corporations with heavy presence in Europe, that run their whole business on Microsoft cloud, including keeping and processing there privacy-sensitive data, business-critical data and medical data, and yes, that includes using some of this data with LLMs - hosted on Azure. Companies of this size cannot ignore regulatory compliance and hope no one notices. This only works because MS figured out how to keep it compliant.

Point being, if there are business consequences, you'll be better off using Azure-hosted LLMs than running a local model yourself - they're just better than you or me at this. The only question is, whether you can afford it.

My first thought is a nice way to save a stream in whatever format you want (e.g. transcode for watching on an old phone or something on your commute), just ffmpeg -i <stream> and then all your usual video format options, instead of having to download it and then convert it afterwards.

ffmpeg also has some processing abilities of its own, so you could e.g. greenscreen (chroma key) from a stream onto an existing video background.

ffmpeg is a pretty low-level building block and as others have said, it's mostly used as a library - a lot of video players or processing tools can now add support for stream inputs easily, and that's probably where the biggest impact is.
by moduspol | 2025-06-05 01:11:55+00:00
Well, my claim was fairly specific, so it's quite easy.

There are ~42k traffic fatalities in the US each year. Cameras-only self driving cars are a tiny fraction of the number of total cars.

The highest estimates I've seen for annual traffic deaths with an ADAS involved (not even implying causation) is in the range of dozens. Cameras-only self driving cars would be a fraction of those. As a result, there are quite possibly more than a thousand traffic fatalities each year caused by human-driven cars for each ONE caused by a cameras-only self driving car.

But my original claim was only that they kill a lot fewer. That seems self-evident.

Almost all flight during this stage of development was reckless. It took a long time for us to collectively learn the lessons as pilots, mechanics, engineers, logistics, etc, to make it safe. A great source of reckless piloting stories are from the Alaska bush in the 1920's. People like Eielson and Wilkins managed to land on drift ice and fly from Alaska across the Arctic Ocean to Europe in 1928. A great book to read about this is The Flying North by Jean Potter (1946), which chronicles the Alaska bush pilots from the 1900s to 1940s, when she was stationed in Alaska during WWII.

I think it's less about trying to get wins (most understand that congress dems are the minority) and more about resisting these anti-citizen acts as much as possible. Having 4 or 5 democrats vote on an R bill a few months back really put a nasty taste in people's mouths. Among all the crazy cabinet appointments that some voted on

Basically, the democrats want fighters. We're well past bi-partisan tasks where we should just faciliate any kind of bill that comes up. Because very few are reasonable.
