Ceph RBD can technically support multi-writer access through exclusive locking, but it won't be the same as multi-writer.

You can set up a radosgw outside of the proxmox and use objects.

But ceph is fundamentally a distributed object store, shared LUNs with block level multi-writer is fundamentally a tightly coupled solution.

If you have a legacy need that has OCFS or a quorum drive, the underlying tools proxmox is an abstraction can sometimes be used as these types of systems tend to be pets.

But if you were just using multi-writer because it was there, there are alternatives that are typically more robust under the shared nothing model like Ceph uses.

But it is all tradeoffs and horses for courses.

I understand the push to build fabs in the US to avoid tariffs, as the US likely sees this as a strategic hedge for the global chip supply in case China disrupts Taiwan or Japan, or some other rare catastrophic event occurs.

Whether it is correct or not, Trump seems to view the US as a larger version of Mar-a-Lago, so he'll always feel he can charge a premium for access to its consumer base and market while offering discounts to those he sees as ingratiating themselves.

But it is supposed to be a free market that should reward efficiency and competence, not prop up companies that don't have their act together. If the goal is domestic chip production, funneling funds to TSMC's proven fab operations and to build more US fabs makes more sense than bailing out Intel, regardless of whether it is improper to demand such concessions at all.

You'been answered already about the support periods in Android, but let me add more for you (and others mentioning support times of the system): in Android this problem doesn't exist to begin with. The fact that getting a new web browser version is anchored to getting a whole new operating system version, is preposterous and absurd, pure planned obsolescence from Apple. You would just upgrade your Chrome, Brave, Firefox, or whatever browser app, and do with them what your were trying to do. (in this case install a browser extension, for which the best one qould be Firefox).

This situation with iOS sounds as ridiculous as if it was mandatory to upgrade from Windows 10 to Windows 11 in order to update the Edge browser. (Edited to remove useless rant)

Okay, whatever about ADSL2+, why on earth would anyone still be doing ADSL1? Are they buying the DSLAMs off eBay? Like, I'm legitimately surprised that they can still get the equipment; you'd think it'd be cheaper just to go to ADSL2+.

10 years ago I had ADSL2+ at home (basically due to planning issues; traditionally, urban phone stuff had been hidden underground, and the telecom was having trouble getting planning for VDSL street cabs), and that felt like living in the past back then. ADSL1, today, is absurd.

When the life expectancy was 35, nobody was dying of old age at 35. There were still septuagenarians. To provide an intentionally simplified example, a population where half of the people die of old age at 70 and the other half die in childbirth at age 0 has a life expectancy of 35. Even adding ten years to the life of every adult in that population only improves life expectancy by five years. Reducing infant mortality was a much better investment, though (fortunately!) we’ve been so successful at it that we may be at a point of diminishing returns.

Interesting to contrast that with the assessment of React, qua critique of the Observer pattern in Brandon Rhodes' 2022 design patterns talk: https://www.youtube.com/watch?v=pGq7Cr2ekVM?t=28m45s . (Notably, later in the talk when he describes the Mediator pattern with a GUI-motivated example, he preempts by saying "I know I just told you to use React"... but then the description ends up sounding to me very much as if React is an implementation of the Mediator pattern!)

I tested a consortium of qwens on the brainfuck test and it solved it, while the single models fail.

MOEs are a single model. An 'expert' is a subset of layers chosen by a router model for each token. This makes them run faster. A consortium is a type of parallel reasoning that uses multiple of the same or different models to generate parallel response and find the best one.

All models have a jagged frontier with weird skill gaps. A consortium can bridge those gaps and increase performance on the frontier.

Nothing will change in the US if Ukraine falls tomorrow.

People love to cry foul when the US flexes it's might... then cry foul when the US takes a back seat... literally cry foul no matter what the US does.

If Ukraine is so important to the world order, why has Europe (you know, Ukraine's actual neighbors) not stepped up with their full military power? Why is Europe not threatening troops, missiles, aircraft, tanks, etc... even nuclear obliteration if Putin doesn't yield? Why is it the US has to swoop in, from half a world away, and save the day (again, and again, and again...)?

The US is not currently willing to send our citizens to die in Ukraine. Maybe Europeans should?

> But Bangladesh isn’t the way it is because of Bangladeshis, and it’s “racist” to suggest that importing 50,000 Bangladeshis to an enclave in the US would recreate dynamics that prevail in Dhaka

And that's fine to say. However, it isn't acceptable to invent a story that these Bangladeshis are eating pets with the goal to get everyone else to hate them though, especially when the place in question actually majority likes them, and was even asking for extra resources to help them.

It’s quite rare for the average website to actually hit 1Gbps, that’s certainly true. Nobody makes webpages big enough to hit that speed, or even for that top speed to matter.

But I can download games from Steam at approximately full speed, for example. I subscribe to Ziply Fiber, and they certainly don’t throttle their users or oversubscribe their bandwidth. That said, there are other factors at play as well: can you even maintain 1Gbps to your _hard drive_? Can your computer decompress the downloaded data as fast as it comes in? Steam will slow down the download to match the speed at which it can decompress the data and write it to your disk.

Nice! You definitely have something there.

I would love a dictionary lookup. I'd expect a big part of the strategy to be working backwards from the possible 1/2 letter words, but there's no way to tell how reasonable the dictionary is without testing, and getting the game into the proper state to test would be just as hard as solving the puzzle in the first place.

Having two separate goals (eliminate all letters, find all the words) seems confusing. Honestly I find the latter to be a fairly tedious prospect, but the game really seems to push you toward it especially with the colors on the calendar depending on the % of words found. "Damn it, I got a perfect score with no undos, and all I have to show for it is a red square showing how bad a job I did!"

The UI (on a desktop) felt kind of broken at the start because nothing has hover effects. Anything clickable would benefit from some kind of an effect, but especially the letters on the words. If you don't want color changes or animations, at least set the cursor style.

Eh, this seems like a take that reeks a bit of "everyone is stupid except me".

I do know the answer to OP's question but that's because I pickle my brain in this stuff. It is legitimately confusing.

The analogy to different SKUs strikes me also inaccurate. This isn't the difference between shoes, shirts, and shorts - it's more as if a company sells three t-shirts but you can't really tell what's different about them.

It's Claude, Claude, and Claude. Which ones code for you? Well, actually, all of them (Code, web/desktop Claude, and the API can all do this)

Which ones do you ask about daily sundry queries? Well, two of them (web/desktop Claude, but also the API, but not Code). Well, except if your sundry query is about a programming topic, in which case Code can also do that!

Ok, if I do want to use this to write code, which one should I use? Honestly, any of them, and the company does a poor job of explaining why you would use each option.

"Which of these very similar-seeming t-shirts should I get?" "You knob. How are posts like this even being posted." is just an extremely poor way to approach other people, IMO.

All IoT devices on my network go into a VLAN that blocks internet access. Using Unifi, I think it's just a checkbox to turn internet access on/off. I use a virtual nic on my Home Assistant VM that recognizes that vlan and can communicate with all those devices, as well as a separate nic which is hooked up to the main vlan.

Tirzepatide (and likely other GLPs) have limitations that are rarely brought up in the general media

- Patients have about 72 weeks to reach maximum loss, they don't lose any more weight after 72 weeks even on the highest dose.

- Patients appear to immediately gain the weight back as soon as they stop taking it.

It's right in the phase 3 trial outcomes paper:

I suspect that this info is intentionally down-played so that it doesn't affect sales.
Show HN: Empromptu.ai – No code, AI app builder with RAG, model, evals etc.
by anaempromptu | 2025-08-05 19:09:32+00:00
Hey HN! We're Empromptu.ai, an AI app builder that builds AI apps (RAG, models, evals all built in every app)

Demo: https://app.storylane.io/share/rtneodkf5i1l

We started Empromptu after burning through thousands of credits on AI builders and hitting the same problem: cool looking prototypes or demos that break with real users.

The issue wasn't the building process, it was accuracy. Most AI applications plateau at 60%~ reliability, which is fine for prototypes but it's unusable in production. We realized these tools aren't really "AI app builders", they're website builders that happen to use AI.

We wanted to solve the hardest problem first: making AI applications actually work reliably.

Our approach centers on what we call dynamic optimization. Instead of cramming every possible scenario into one massive prompt (which confuses LLMs), our system adapts contextually. A travel chatbot automatically knows to mention LAX for Los Angeles vs. Pearson for Toronto. This consistently delivers 90%~ accuracy versus the industry standard 60%~.

But accuracy alone wasn't enough because we also needed to solve the builder gap:

- Simple builders (Lovable, Bolt): Create static websites, not AI applications

- Complex ML tools: Require dedicated teams most startups don't have (Arize, Voxel51) - we've also heard from both technical and non-technical founders that they found these tools very complex

- What's missing: Tools that build applications where AI is embedded functionality

So we built AI agents with optimization built-in. Users just type what they want to build and our agents handle the full development pipeline: creating applications with embedded models, RAG and intelligent processing. You can deploy to your own infrastructure via Netlify, GitHub or download it directly since you can run it locally.

The result: Startups, solo hackers and enterprises can build AI apps or AI features without hiring a dedicated ML team.

Waitlist: https://empromptu.ai

We'd love feedback from the HN community — esp. if you've hit similar accuracy problems or thoughts on the technical approach.

Nah. A friend with OCD isn’t constantly telling me I’m wrong about everything I say. Being around active contrarians (code phrases: “as the devil’s advocate”, or “yes, but actually…”) is freaking exhausting. It imposes a lot of psychic weight. A true friend will tell you your wrong when you’re being wring, but isn’t going to feel the need to lecture you about the difference between teal and cyan if you make a slip of the tongue about a random car’s color.

It’s not my job in life to be everyone’s personal therapist, for free, at the expense of my own sanity. I’d rather hang around with people who don’t make me wince and brace for their “correction” every time we talk.

JPEG-XL is supported by a lot of the most important parts of the ecosystem (image editors and the major desktop operating systems) but it is a long way away from "everything". Browsers are the most major omission, but given their relative importance here it is not a small one. JPEG-XL is dead in the water until that problem can be resolved.

If Firefox is anything to go off of, the most rational explanation here seems to just be that adding a >100,000 line multi-threaded C++ codebase as a dependency for something that parses untrusted user inputs in a critical context like a web browser is undesirable at this point in the game (other codecs remain a liability but at least have seen extensive battle-testing and fuzzing over the years.) I reckon this is probably the main reason why there has been limited adoption so far. Apple seems not to mind too much, but I am guessing they've just put so much into sandboxing Webkit and image codecs already that they are relatively less concerned with whether or not there are memory safety issues in the codec... but that's just a guess.

The environmental impacts of wind and solar are nonzero but absolutely miniscule compared to fossil fuel extraction. Base load is a concern but not unsolvable especially as scaling batteries becomes easier. Most importantly, solar + battery is already deployed at scale and is now the cheapest to install and operate in the real world. We are also close to being able to scale geothermal as renewable base load.

Fusion is great but it's still years away at least from a single viable commercial reactor. We need solutions to be deployed ten years ago. Waiting for Godot isn't an option.

I don't disagree that being novel has it's place in framing art, and I still believe that a Fountain Factory could certainly be framed as art.

To your other point, sorry, but artistic/aesthetic essentialism hasn't been serious position for at least a hundred years.

As long as there is a perceiver, there is a frame.

The idea that nature is intrinsically beautiful is a frame. It's fine to hold that but it shouldn't be confused with not having a frame.

I actually think this is an interesting question because of inflation. Like I understand the theory, but I think this would be limited to entertainment or some kind of IP as the person mentioned. A one-person billion dollar game? Yes, maybe one-person selling or reselling a proprietary algorithm or something like that, but certainly not anything with sales overhead, if there's no IP, then a three person company with AI could run circles around a 1 person company with AI.

thank for the pointer !

The syntax seems cool and comprehensive, i like it.

I made some test and like its name, it is very fast : performances are closed to SimpleW, just a little bellow. But its memory footprint is the half, so i'm impressed. I will check the code, sure there are interesting things into.

The marginal cost of software is zero and therefore the just price in a perfect market is zero. You can compete on delivering features quickly (and that's how all 80-00s software was - they were able to charge simply because no one was offering same features yet), but other than that there is no way software can be a profitable product without being a monopoly - and monopolies is not a thing to be tolerated. You can sell customer support, you can sell services, you cannot really sell software forever. Hate this as much as you want, but that's how things are.

TSMC built a fab in Arizona that in 2 years was up and running delivering chips to Apple, so it doesn't take that long ...

Obviously a protracted or nasty war would have a severe impact, but it's hard to see why China would want to harm TSMC, even if worse case for US they stopped them from exporting.

What are you on about?

The Agda compiler, Pugs, Cryptol, Idris, Copilot (not that copilot you are thinking of), GHC, PureScript, Elm…

These might not be mainstream, but are (or were for Pugs, but the others are current) important within their niche.

Machines suffer mutation rate too. Cosmic ray induced bitflips could be possible. Although since we are all spitballing anyhow maybe you can handwave a cosmic shield along with your cosmic explorer.

It would also be interesting if the host system collapsed. That would be some interesting scifi fodder: advanced civilization sends out probes but by the time FTL visitors show up, their civilization already collapsed to the stone age.

This reminds me of one of my favourite exchanges in a detective story:

'Dear me!' said Miss de Vine, 'who is that very uninspired young woman? She seems very much annoyed with my review of Mr. Winterlake's book on Essex. She seems to think I ought to have torn the poor man to pieces because of a trifling error of a few months made in dealing, quite incidentally, with the early history of the Bacon family. She attaches no importance to the fact that the book is the most illuminating and scholarly handling to date of the interactions of two most enigmatic characters.'

'Bacon family history is her subject,' said Miss Lydgate, 'so I've no doubt she feels strongly about it.'

'It's a great mistake to see one's own subject out of proportion to its background. The error should be corrected, of course; I did correct it--in a private letter to the author, which is the proper medium for trifling corrections. But the man has, I feel sure, got hold of the master-key to the situation between those two men, and in so doing he has got hold of a fact of genuine importance.'

-- Gaudy Night, D.L.Sayers (1935)

I think comment sections tend to bring out the "feels strongly" responses where the "private letter" ones would be more appropriate.

While Gaudy Night is a detective story, it's just as much a love letter to Oxford academia (the author being an alumni).

Claude.ai, ChatGPT, etc. are finished B2C products. They're black boxes, encapsulated experiences. Consumers don't want to pick a model, or know what model they're using; they just want to "talk to AI", and for the system to know which model is best to answer any given question. I would bet that for these companies, if their frontend observes you using the little model override button, that gets instrumented as an "oops" event in their metrics — something they aim to minimize.

What you're looking for, are the landing pages of the B2B API products underlying these B2C experiences. That would be https://www.anthropic.com/claude, https://openai.com/api/, etc. (In general, search "[AI company] API".)

From those B2B landing pages, you can usually click through to pages with details about each of their models.

Here's the model page corresponding to this news announcement, for example: https://www.anthropic.com/claude/opus

(Also, note how these B2B pages are on the AI companies' own corporate domains; whereas their B2C products have their own dedicated domains. From their perspective, their B2C offerings are essentially treated as separate companies that happen to consume their APIs — a "reference use-case" — rather than as a part of what the B2B company sells.)

Back in the days, one could hang out on IRC and make many friends there. But now the tribe has been split into smaller, more focused walled gardens. I wonder if there exist some online caffee in some corner of the internet where solopreneur can chill casually amongst peers? Local startup meetups are full of poseurs, I miss the decomplexed yet friendly IRC experience.

I’ve seen good LLM summaries.

LLMs are best at using words and phrases that “flow well”. Sometimes they write nonsense that flows well (even the summaries have to be checked because sometimes the meaning is different), but sometimes they find better words and phrases that I couldn’t find myself.

They’re especially good if you have almost stream-of-consciousness writing and can’t bother to rephrase it yourself, e.g. you’re writing a boring technical report. Even for something where quality is important, like an epic story: you can write a very rough draft, revise with an LLM, then revise manually.

Dunno if I need to comment on the first point since "will AI be able to Uber itself" is talked to death by zitron, and if we're disagreeing on their ability to turn a profit later on, then talking it out isn't gonna change much.

>>the entire media industry is pushing for everyone, everywhere, all of the time

>No

Yes it is. You can't just "no" this. People aren't just "happily using AI and getting bothered by the EVIL AI haters!!!". The push for AI is literally made of threats "You WILL get left behind", "people WILL replace you". Even if it is undeniably disruptive, you can't not call that pressure on a very large scale.

Just because I ask copilot once every few days to write me a piece of boilerplate doesn't invalidate the fact that my workplace has been made to believe prompting is an "essential skill" that must be enforced via mandatory e-learnings.

>think that they can make AI go away by canceling Altman.

I didn't say that and I don't think that. That last paragraph's basically bait.

Isn’t it that hardware catches up and becomes cheaper? The margin on these chips right now is outrageous, but what happens as there is more competition? What happens when there is more supply? Are we overbuilding? Apple M series chips already perform phenomenally for this class of models and you bet both AMD and NVIDIA are playing with unified memory architectures too for the memory bandwidth. It seems like today’s really expensive stuff may become the norm rather than the exception. Assuming architectures lately stay similar and require large amounts of fast memory.

No. Israel ongoing genocide or the displacement of Palestinians to Egypt will just go faster than ever. The so-called 'international states community' did nothing to prevent any of the US-approved war crimes (either now by Israel in Gaza or the many other historically committed by the US and its aliases), and they will also do nothing when Israel continue to ethnically cleanse the rest of Palestine and destabilizing every neighbor country (Take Syria and Lebanon for example. Other countries that are partially controlled by the CIA -Egypt and Jordan- will have the same upon a regime change or a revolution); therefore violence, both by Palestinians and Israelis, will continue.

Yeah, if it serves OP as consolation I've been in full time employment 9 yrs. Sick of 'socialising' and I'm building my own thing with 0 people to take with me. I need full agency, I'm done with death by thousand feedback. The grass is indeed greener and I'll probably miss working with people... in 2-3 years. We'll see.
