> I think a lot of us want the same thing

Cognitively, yes. This is like saying "a lot of us want the same thing - healthy, fresh food that makes us stronger, sleep better, and live longer". Of course. But fast food is a $400B industry in the US. Social media is fast food. Nobody says they want it but their behavior indicates otherwise.

Wait until they find out about all the Chinese made action cameras that not only require a cell phone but require all the permissions. Some of those gather just as much data as the drones and drone apps. Banning them would be much more difficult as they have dozens of shell stores on Amazon with different company names and different product names but the hardware is made by the same people. When they get too many 1-star reviews they just make a new front. The phone app continues gathering data even when the camera is not in use.

I am curious if that is the same risk governments are concerned with regarding DJI the phone apps. That would be a great means to track the movement habits of government officers, congress critters and soldiers. They can make their own people install management agents but there would be no control over phones belonging to spouses and children. IIRC there was an issue in the past regarding children's toys leaking information to foreign actors.

But dB without reference makes sense in many many occasions. Either because the reference is implicit (not ideal, but we have many implicit assumptions in communication), or because it's genuinely a ratio. Attenuation, gain.

If you every find an "official" written document that uses dB not as attenuation/gain and is not specifying the reference (at least in a footnote), it's written either by idiots or for idiots, or both.

Yes that sounds spot on.

I don't know instagram, but I would expect any provider to be handle almost any container/codec/resolution combination going (they likely use ffmpeg underneath) and generate their different output formats at different bitrates for different playback devices.

Either instagram won't accept av1 (seems unlikely) or they just haven't processed it yet as you infer.

I'd love to know why your commend is greyed out.

What is this thing for?

That is going to be a hard no in so many contexts. Hospitals, gyms, many work environments, my house, the list is going to be long. We know the companies can’t keep their government from forcing access at some point or another. We also know at some point a zero day exploit will allow pin point targeting of who you want to spy on. We see this already on mobile phones.

Edit: When I read the archive link above I can’t actually see the quote referenced.

livestream here: https://youtu.be/EvtPBaaykdo

my highlights:

1. Coding ability: "Claude Opus 4 is our most powerful model yet and the best coding model in the world, leading on SWE-bench (72.5%) and Terminal-bench (43.2%). It delivers sustained performance on long-running tasks that require focused effort and thousands of steps, with the ability to work continuously for several hours—dramatically outperforming all Sonnet models and significantly expanding what AI agents can accomplish." however this is Best of N, with no transparency on size of N and how they decide the best, saying "We then use an internal scoring model to select the best candidate from the remaining attempts." Claude Code is now generally available (we covered in http://latent.space/p/claude-code )

2. Memory highlight: "Claude Opus 4 also dramatically outperforms all previous models on memory capabilities. When developers build applications that provide Claude local file access, Opus 4 becomes skilled at creating and maintaining 'memory files' to store key information. This unlocks better long-term task awareness, coherence, and performance on agent tasks—like Opus 4 creating a 'Navigation Guide' while playing Pokémon." Memory Cookbook: https://github.com/anthropics/anthropic-cookbook/blob/main/t...

3. Raw CoT available: "we've introduced thinking summaries for Claude 4 models that use a smaller model to condense lengthy thought processes. This summarization is only needed about 5% of the time—most thought processes are short enough to display in full. Users requiring raw chains of thought for advanced prompt engineering can contact sales about our new Developer Mode to retain full access."

4. haha: "We no longer include the third ‘planning tool’ used by Claude 3.7 Sonnet. " <- psyop?

5. context caching now has a premium 1hr TTL option: "Developers can now choose between our standard 5-minute time to live (TTL) for prompt caching or opt for an extended 1-hour TTL at an additional cost"

6. https://www.anthropic.com/news/agent-capabilities-api new code execution tool (sandbox) and file tool

Any company in this space outside of the top few should be contributing to the open-source tools (Aider, OpenHands, etc.); that is a better bet than making your own tools from scratch to compete with ones from much bigger teams. A couple folks making harnesses work better with your model might yield improvements faster than a lot of model-tuning work, and might also come out of the process with practical observations about what to work on in the next spin of the model.

Separately, deploying more autonomous agents that just look at an issue or such just seems premature now. We've only just gotten assisted flows kind-of working, and they still get lost--get stuck on not-hard-for-a-human debugging tasks, implement Potemkin 'fixes', forget their tools, make unrelated changes that sometimes break stuff, etc.--in ways that imply that flow isn't fully-baked yet.

Maybe the main appeal is asynchrony/potential parallelism? You could tackle that different ways, though. And SWEBench might be a good benchmark still (focus on where you want to be, even if you aren't there yet), but that doesn't mean it represents the most practical way to use these tools day-to-day currently.

The machine from the article - a 2012 MBP Retina with 16 GB memory and 2.6 GHz i7 - had cost $2999 in the US (and significantly more in most of the rest of the world) at release. That's around $4200 today adjusting for inflation. You won't see many Dell laptops with that sort of price tag.

Or, how do you prompt yourself daily?

I often find myself doing decisions that I forget about next day. Or do something for a week and never return to it the next week.

Daily notes in Obsidian help a bit. But I feel the lack of mentor figure that I can tell about my progress. Maybe some LLM app can do that.

Sure stamps are collectible, and have some value, but at the end of the day it should be within reason. At the end of the day stamps are simply brightly coloured bits of paper, and their price should reflect that. Some of the more expensive stamps go for hundreds of thousands of dollars, even millions, which goes so far beyond what is reasonable that the only logical explanation is that the buyers are paying purely for status. Which makes them no different from NFT's.

The point of units is to indicate both what dimension, and relative magnitude in that dimension, is being talked about clearly.

In virtually any other situation, leaving off units and counting on context to fill them in would be considered to be at the extreme end of unacceptable.

The unit problems in question, are only accepted because they are an historically created anomaly. Not because they are a good idea, or anyone wanted that outcome.

This is great! I hope somebody adopts and publishes such a package.

There are some pieces of widely used software (numpy, git, regex...) that are very powerful but can be highly complex, to a point where reading them is much harder than writing them with trial and error. I hope we see more projects like this, that add layers on top of those, to make them readable without making them less performant.

(Such projects likely exist already, of course, so they just need to be polished and spread)

Being a designer myself, but in the interest of public good, I will share my design here and urge anyone else to copy it. The ideal form factor for this device is a cowboy hat. Here's why

1. Such a device will require significant local compute, generating a lot of heat. It cannot be too close to the body, and require efficient cooling. In the cowboy hat, the processing can be placed above the head in the bucket of the hat, and the cooling dispersed in a large surface area around the brim

2. Such a device requires 360 degree camera vision, thus cannot be a backpack or vest type design (which also bring heat too close to the body). It also must be close to eye level (cannot be shoes).

3. Has to be able to be worn in any environment, with any style. A cowboy hat is great for sun protection, and in the rain.

None of it makes any difference because they've managed to be worth over 300 billion without an ounce of moat.

This shit is gonna go nuclear, and probably soon. Valuation is utterly detached from reality for the mediocre products they've shipped and the only reason it's still going is the tech sector doesn't have anything else to show for itself. Purchasing user numbers must be absolutely pathetic what with the complete silence on them, and even their highest tier paying customers have them hemorrhaging money, let alone all the cheaper/free ones.

Microsoft clearly got tired of being the pay-pig and is scaling back datacenters. OpenAI is supposedly taking up that stock but the projects are stalling because OpenAI doesn't have any money. Softbank is supposedly funding them but it also doesn't have the money, which is a huge issue what with them being the only substantial investor. And that's JUST for THIS YEAR. By all accounts they'll need dozens more billions for 2026.

For what? Chat bots and boring pictures/video that nobody aside from AI hype people give the slightest damn about.

Like, to put this in perspective: OpenAI is supposedly worth a tenth of what APPLE is worth. Fucking APPLE. Love em or hate em, Apple is one of the most valuable companies on the fucking planet, for a reason. What on Earth is OpenAI shifting in terms of actual products-to-customers that deserves to be in the same ZIP code as the Mac, iPhone or iPad?

Ludicrous.

transpiled code is rarely good. Rust is often better than C for SIMD code (it actually has useful SIMD instructions exposed, and aliasing guarantees make it a lot easier for the compiler to figure out obvious optimization. By transpiling, however you loose most of the structure of an idiomatic project and generally make a bit of a mess of things.

I'm not a fan either, but I think it's inevitable that everything we do, at least in any not 100% private space, will be recorded in the not distant future.

Because recording will be so very cheap and useful.

As an example, my car has at least 5 cameras that are constantly on. This is - or will be soon - true for all cars. So anytime you can see a car, you're being recorded.

The dude's 77, for one. A lot of people retire long before that age. Second, it's not hard to find articles about his retirement that state his reasons.

One example: https://www.technologyreview.com/2023/05/01/1072478/deep-lea...

> And more generally, doesn't AI allow more people to never retire?

I don't understand what you mean. It's arguably forcing some people out of work. And I'm not sure what about "AI" (I'm supposing you mean specific techs like LLMs?) would help people not retire...or why that would be a good thing.

I don't figure out individual tasks but will figure out what projects I want to work on and for how long. I dont' view these as hart committments but it definitely makes it easier for me to start the day with focus instead of trying to remember where I left everything yesterday.

What's the other one they are tying together? Presumably the first one is the commit...

No it's not. This is why version control exists in programs that generally don't deal with code, s.a. Microsoft Word for example.
Show HN: MCP-UI – SDK that embeds interactive UI snippets via MCP
by adusal | 2025-05-22 16:41:36+00:00
Hey, We've just open-sourced MCP-UI, a project that provides lean client and server SDKs to enable passing rich, interactive UI components over vanilla MCP. We believe it'll enable a future where AI interaction will be based on UI snippets for interactive experiences.

MCP-UI is meant to be a playground to bootstrap the initiative. Hopefully, through experimentation, the community can find the best way to enable this new future.

Under the hood, the SDK enables any MCP server to respond with an EmbeddedResource with a "ui://" URI. The client SDK allows hosts to render it using a supported method (currently raw HTML or an external app) and handles follow-up interactions through events (e.g., further tool calls). We need better delivery methods, starting with React Server Components and Remote-DOM for better security. There are many other things to accomplish, such as scalable protocol negotiation.

You can build with it today -

GitHub: https://github.com/idosal/mcp-ui (see demo video)

Docs: https://idosal.github.io/mcp-ui

UI-enabled chat client with compliant sample server: https://scira-mcp-chat-indol.vercel.app (type "show tasks" to see it in action!)

Inspector for local development: https://github.com/idosal/ui-inspector

Further reading on UI in MCP: https://github.com/orgs/modelcontextprotocol/discussions/287

Thoughts, changes, and contributions are more than welcome! Can't wait to see what we can build with it.

> But in many fields they aren’t.

I am lost. What fields you are talking about?

1. I am unaware of any field operating within its own echo/context chamber using unit-less numeric notation for anything but actual unit-less quantities. Except for informal slap-dash arithmetic, on trivial calculations.

2. Units indicate the dimension being measured, not just the relative magnitude within that dimension. Nobody is going to know from any shared context, except in person, what a bare number measures.

3. Virtually every measurable quantity has multiple possible units of different relative magnitude, depending on micro context, so even people within a field, who agree on the dimension measured, still need units. Meters, light years, AU, angstroms?

4. You cannot apply standard formulas of physics, or anything else, without specific units. Formulas operate on dimensions, but to interpret and calculate any numbers, you need to know the specific unit being used for each dimension.

(In any context, but a late night napkin argument between two well acquainted colleagues in a bar, units are universally used. And in that case, the opportunity for serious misunderstandings is more likely to be from missing units, than the quantity of scotch each has imbibed, or how much they have spilled on the napkin.)

Hey HN,

Came across this site, veo3.co, earlier today. It claims to offer free and unlimited VEO3 video generation, which definitely caught my attention given how resource-intensive these models usually are.

I've only played around with it for a few minutes – generated a couple of short test clips out of curiosity, and it seemed to work without asking for payment or hitting any obvious immediate limits. The interface was pretty straightforward.

Haven't dug deep into the output quality across different prompts, video length constraints, or potential watermarking yet. Also curious how they're sustaining a free unlimited model.

Anyone else seen this or given it a more thorough spin? Wondering if there are any catches I'm missing or what the experience is like for more complex generations. Could be a neat resource if it holds up.

Great questions, indeed this is a kingdom of red tape. We realized that our fist users likely will be small providers but who currently lose $$ on denied/delayed claims. Talked to the first cohort of them - rehabs, allergy clinic, men's health clinic, nursing home, etc. We signed the first rehab just 2 weeks after meeting them because we offered to solve their problem in the same way as their 3rd party billing provider does (manually finds mistakes and circles them back to clinicians) for 2x lower price tag. Then we realize this is common situation for many rehabs.

Not where I live. You'd never specify how old somebody is with a bare number and have it mean anything other than years in the US. "My kid is 3" is always 3 years. So is "How old is your Tammy?" "Three". That only ever means years. Every other unit is always explicit. In my decades as a parent and being around other parents of kids and newborns, I've never experienced an exception to this.

> I suspect the future of video compression will also include frame generation

That's how most video codecs work already. They try to "guess" what the next frame will be, based on past (for P-frames) and future (for B-frames) frames. The difference is that the codec encodes some metadata to help with the process and also the difference between the predicted frame and the real frame.

As for using AI techniques to improve prediction, it is not a new thing at all. Many algorithms optimized for compression ratio use neural nets, but these tend to be too computationally expensive for general use. In fact the Hutter prize considers text compression as an AI/AGI problem.
by jmull | 2025-05-22 16:44:40+00:00
Well, you can still have an app server if you want -- having app logic that runs local to the storage doesn't preclude you from also having an "app server" (that is, a place app logic runs that isn't local to the user and isn't local to the storage, but somewhere in between.)

Very typically, that's how it's done with traditional client/server databases.

There's no built-in "wire-protocol" for clients to connect, but there are reasonable options (it's a pretty common pattern, if fact, for systems to have a data service that provides an app-level HTTP interface to data -- so there you go, it's something you might have implemented anyway).

But I think this project would help in the creation of a full/rich application data service without a need for an intermediate app tier.

There are a few reasons people end up with an intermediate app-level data service, but it's starting to seem like a service based on sqlite (running local to the storage, of course) may be able to provide a decent alternative answer in many cases.

I'm imagining a service light-weight enough to run as a lambda or other serverless environment (including fast cold start) which then opens up some interesting things like one-db per user and maybe user-controled host, etc.

“GitHub says Claude Sonnet 4 soars in agentic scenarios and will introduce it as the base model for the new coding agent in GitHub Copilot.”

Maybe this model will push the “Assign to CoPilot” closer to the dream of having package upgrades and other mostly-mechanical stuff handled automatically. This tech could lead to a huge revival of older projects as the maintenance burden falls.
