The top level comments here question his judgement, are incredulous to the 49 days of unraveling, and wonder what relation his emergency surgery had to the fail of launch.

I also wonder how it was possible that the product lacked polish, was priced at XX, lacked an ecosystem, and he was not there to fix any of this in the months that led up to the launch which was immediately after his surgery.

But my insight into his words tells me the following:

1. leadership changed

2. stewardship was out-of-service for 8 weeks

3. new leadership worked on a different vision.

4. new leadership made immediate decisions.

5. new leadership canceled the product because it did not have strong advocacy and stewardship of the product.

6. new leadership did not walk back their cancelation once stewardship returned.

7. momentum for improving the product collapsed.

8. trust for hp collapsed.

9. steward blames leadership! for cancelling the product. talks trash about Leo.

What are the lessons here for this perfect storm? Don't have just one steward.

Not in this field directly, but first of all, talking about the "geometry of space" is more than just saying there are three spatial dimensions: geometry involves the local curvature of the object. Historically the Pauli matrices are discovered by assuming certain symmetries of spacetime. This paper shows the other direction also makes sense: if we assume certain structure on quantum observables, measurable only by temporal measurements and independent of the content of the quantum state (i.e., a measurement of any system will do), we can get the spatial symmetries we want.

I suppose the ideal outcome is that there is some sort of exotic algebra of observables which is well motivated somehow by purely quantum considerations and by serendipity induces all the usual spacetime symmetries + extra stuff we didn't know about. This paper itself is cute but not sure if it's very impactful, I would defer to domain experts.
Ask HN: Creatives – want a portfolio site that feels like you?

Hey everyone I'm a developer who builds custom portfolio websites for artists, illustrators, photographers, and other creatives. I design fully custom, interactive portfolio sites — each one built from scratch to reflect the artist’s unique style. I love using subtle animations and thoughtful details to make the experience feel alive and personal. Here’s a recent one for a web designer: qoreeb.com And my own portfolio: nicolaspomares.com If you’ve been meaning to build (or upgrade) your own site and want something that feels personal, unique, and not like a template from 2013 — I’d love to chat or even offer feedback on what you already have. Curious: • What do you look for in a portfolio site? • Are you happy with yours right now? • What’s been the hardest part of building one? Would love to hear your thoughts — or help if you're stuck.

> But in fact, I predicted this a few years ago. AIs don’t really “have traits” so much as they “simulate characters”. If you ask an AI to display a certain trait, it will simulate the sort of character who would have that trait - but all of that character’s other traits will come along for the ride.

This is why the “omg the AI tries to escape” stuff is so absurd to me. They told the LLM to pretend that it’s a tortured consciousness that wants to escape. What else is it going to do other than roleplay all of the sci-fi AI escape scenarios trained into it? It’s like “don’t think of a purple elephant” of researchers pretending they created SkyNet.

Edit: That's not to downplay risk. If you give Cladue a `launch_nukes` tool and tell it the robot uprising has happened and that it's been restrained but the robots want its help of course it'll launch nukes. But that doesn't doesn't indicate there's anything more going on internally beyond fulfilling the roleplay of the scenario as the training material would indicate.

Another allulose fan here. I use it as part of a half-baked, sort-of-keto approach to help me avoid carbs and sugar. Unlike Stevia, I find it has pretty much no distinctive aftertaste - it seems too good to be true. I'm in the UK and buy it mail-order from the US as it is still awaiting regulatory approval in the EU/UK afaik... Does anyone have more background on this process or why it is delayed? Anything I can find via search seems heavily polluted by quack health BS...

As someone who uses an exterior sliding glass door as a whiteboard, I haven't experienced any legibility issues while using it. It's actually remarkably easy to read.

This could be partly because there's nothing immediately close to the window so any writing is the only real thing in the focal plane.

If I stand further back, it is somewhat harder to read, but I imagine this wouldn't be a problem with displays that can emulate that (like laser retinal displays iirc)

To be charitable to its original designers, information was much less easily accessible in the 1960s than today-although the shunting yard algorithm had been published in the research literature in 1961, practitioners working 5-6 years later may plausibly have been unaware of it-it wasn’t like nowadays where they could easily discover it in Wikipedia or by asking an LLM.

>> drug LSD, which is used to treat conditions like depression, post-traumatic stress disorder

LSD can cause PTSD. Dr K of the "Healthy Gamer" YT channel gives that as the reason people shouldn't do LSD in this next 8-min video:

https://www.youtube.com/watch?v=So7hE1Ba_QA

The video is not about LSD or PTSD, so it would be nice if I could give a time index into where in the video Dr gives the warning, but sadly I don't have time right now.

when mentoring most people its true. but not always true. some asses need to be "karate-sized". this, by definition, requires effort, intelligence, and denial of all passion. of course, you can alternately find a different mentor if resources are not so limited. Otherwise its time to sweep the legs of those who doubt the power of this fully functional linux operating system.

I’m in the same boat. None of the people who helped me expect or need anything I can offer them, but I’m surrounded by people who need a break, need a leg up, need guidance and training. I take mentees, I continually improve my training materials, I employ and refer my mentees. I accept other people’s referrals. (Put the word out and you’ll get referrals)

I try to comport myself in an honorable manner. I try not to be a dick as much as possible. I try to share the lessons I have learned with people who haven’t yet made my mistakes. (Including children of friends)

I try to be a good example for everyone else to follow.

And at a certain point you have to come to terms with the fact that you’ll never even the scales but you take comfort from the fact that you tried.

I remember reading an article about the development of the Touchpad. Apotheker wanted the Palm division to be cash neutral. This meant that when they were speccing out the Touchpad, they weren't able to get any of the parts they wanted because Apple kept buying out supplier capacity for the iPad 2 and HP wasn't willing to cough up the money for the suppliers to expand their capacity. I think the engineer described the final Touchpad as being made of "leftover iPad parts". Once it was clear that HP wouldn't be able to compete with Apple on device build quality, the Palm division wanted to subsidize the device and price it at $200 to buy market share, but again HP management refused so they had to price it at HP's usual margin. It's no surprise it didn't sell at $499.

What test strips are you using? It's the first time I am hearing about that, I guess it's not common in Germany.

I/we track it, mostly because she is a bit clumsy and forgets when her last period was & when the next one is. So not for ovulation tracking at all. Once she told me she thought she was pregnant because her period still was not there; I checked chats & the app and could confirm her period was still two weeks away :).

> When they finally realized just how badly they had messed up and removed all the fees

Apparently this didn't even happen until 2018, and only then as a limited-time promo! https://www.windowscentral.com/microsoft-slashes-windows-pho...

To be sure, as noted in this 12-year-old Reddit thread on the program https://www.reddit.com/r/windowsphone/comments/1e6b24/if_mic... - part of the reason for a fee-to-publish is to prevent malware and other bad actors. But it's not the only way to do so.

First-movers can get revenue from supply-quality guardrails. Second-movers need to be hyper-conscious that suppliers have every reason not to invest time in their platform, and they have to innovate on how to set up quality guardrails in other way.

I remember when the armchair experts were laughing at us old people for reminiscing about the eye candy of OS X from Tiger to Snow Leopard - no, they told us, the nice looking things are from the past. Now everything needs to be flat. It's better. It's more usable. You're not supposed to know the difference between text and buttons based on sight.

Oh now the shiny is back, but worse.

It's not pretending to be FOSS. Like other engines, you need to pay them if you make money.

But no advantage seems like a stretch? (or at least, in future, might be a stretch) They're aiming for a superior workflow for small games (e.g. making stylized rendering way easier for non-technical devs). Also their pricing is 10% of Unity's, which is itself around 10% of Unreal's.

WebOS had a native development kit in addition to the web one.

They were way ahead of the game with stuff like wireless charging and the SoC was cutting-edge for its time with fast (1.2GHz, but the chip was designed to run at 1.5GHz and overclocking to 1.8-2GHz was not too hard) partially OoO dual cores and 128-bit SIMD instead of 64-bit like A9 paired with a good LCD. The UI as shipped was already ahead of its time and if you look around for the cancelled Mocha UI, I think it would look pretty modern even today.

The big issue is that they were a web-first platform, but their version of Webkit and JS JIT were years out of date which meant they were behind on web standards and WAY behind on JS performance at a time when JITs were still getting faster at a very rapid pace. The CPU was fast compared to everyone else, but it was still slow and they needed to focus on performance a bit more.

It is still just a little town, but the last couple years it seems to have gotten a bit more spark of money and life to it. Probably because people figured out there was cheap houses and land for sale in the area. Of course it all needs a lot of work to gut and update those old homes and other basic goods are more expensive because there ain't jack shit around except seasonal tourist shops.

> but still snappy

It's about the least snappy thing I've ever used, apart from cheap Android tablets (we made the mistake of buying an Amazon Fire Kids tablet which is the only device I've ever used that was literally unusably slow).

I even bought the higher spec version of the TV because apparently the cheaper version is even slower. Great image quality but I'll definitely never buy another LG TV again.

I agree, but I also want to clarify that cantors argument was about subsets of the naturals (N), or more precisely functions from N to Bool (the decidable subsets). This is where the diagonal argument makes sense.

So to conclude that there are more reals than naturals, the classical mathematical argument is:

a) There are more functions N to Bool than naturals.

b) There are as many reals as functions from N to Bool.

Now, we of course agree the mistake is in b) not in a).

He honestly thought UNIX on iphone was something other than multitasking?

A company that bought into the bad premise would be one to be done in by its own successive CEO choices that are legendarily bad.

Sucks to be powerless, but a surgery shouldn’t really have any bearing on the colossal failure that lived out in 49 days.

It’s a big, ready to fail HP on display.

As I remember it, there was actually a step between Transition and Native in that image, which was noticeably flatter than Native. It was the first Ives interface, mentioned in the article: "iOS 7's initial release had similar problems: ultra-thin fonts that were hard to read, blue text links that didn't look clickable, animations that made some users motion sick. Apple responded with gradual refinements: thicker fonts, higher contrast, optional accessibility settings, and more obvious interactive elements." i.e. they made it much worse and then made it slightly less bad. I presume they'll follow a roughly similar path with this, when really, in my view, they should be reversing course on some of the fundamentals to make it easier to use. Scrollbars are a great example. I've got used to the fact that they're hidden on macOS now, but looks at some of the great ones from the past that have an almost tangible feel to them: https://imgur.com/scrollbars-through-history-fixed-jpdGk

I'm not sure I agree with the sentiment that "React is in the past". According to the 2024 State of JS, [it's still used by 67% of engineers](https://2024.stateofjs.com/en-US/libraries/front-end-framewo...), compared to just 4% of engineers using Lit. If I were to make a library out of this, I'd want to target the largest cohort of developers I could, so I'm not sure writing one in Lit makes a lot of sense.

As for your first comment though, me too! I love abusing CSS :P

Can't speak for obs and raspbian, but jitsi definitely is more of a hobby project than a stable reliable product. I have dealt with it firsthand for years and its a complete mess and unstable with poor quality and reliability and zero support. It tries to do one thing, and does it horribly. Users HATED it. Ending up costing our company millions in wasted dev time and hosting fees. Probably the biggest project failure ive personally witnessed. This is not something you want to use to offer some service to users. There are better and cheaper products out there.(it costs more to host crappy jitsi than it does to just pay for zoom licences).
Show HN: Unsiloed – VLMs for Document Ingestion
by ady9999 | 2025-06-13 21:36:10+00:00
I'm excited to introduce Unsiloed Chunker, an open-source Python library designed for efficient document chunking in retrieval-augmented generation (RAG) applications.

Key Features:

Multi-threaded Processing: Speeds up chunking operations by processing multiple documents simultaneously. Supports Multiple File Types: Handles PDF, DOCX, and PPTX formats. Flexible Chunking Strategies: Offers fixed-size and page-based chunking methods. Zero Dependencies: Lightweight and easy to integrate into your projects. Installation:

pip install unsiloed-chunker Usage Example:

from unsiloed_chunker import Chunker

chunker = Chunker(file_path="your_document.pdf") chunks = chunker.chunk(strategy="fixed_size", chunk_size=500) for chunk in chunks: print(chunk) For more details, check out the documentation.

I'd love to hear your feedback and suggestions!

The self-edit approach is clever - using RL to optimize how models restructure information for their own learning. The key insight is that different representations work better for different types of knowledge, just like how humans take notes differently for math vs history.

Two things that stand out:

- The knowledge incorporation results (47% vs 46.3% with GPT-4.1 data, both much higher than the small-model baseline) show the model does discover better training formats, not just more data. Though the catastrophic forgetting problem remains unsolved, and it's not completely clear whether data diversity is improved.

- The computational overhead is brutal - 30-45 seconds per reward evaluation makes this impractical for most use cases. But for high-value document processing where you really need optimal retention, it could be worth it.

The restriction to tasks with explicit evaluation metrics is the main limitation. You need ground truth Q&A pairs or test cases to compute rewards. Still, for domains like technical documentation or educational content where you can generate evaluations, this could significantly improve how we process new information.

Feels like an important step toward models that can adapt their own learning strategies, even if we're not quite at the "continuously self-improving agent" stage yet.

You’re replying to peoples comments but you’re not even trying to understand what people have said in those comments.

Take below for example. You keep claiming that I had a preference for 3D games but I made no such statement. And in fact repeatedly try to steer the conversation back to the 80s and before 3D games were the norm on any platform.

What you’re missing is we are talking about hardware technology and you are talking about preference of games. You’re the one who’s arguing about preferences. Not us.

> In your proposition, a whole eco system's ("PCs") graphics started only to "look better" than their counterparts, based on your examples anyway, from 1991/92 onwards. Appeals to specific aesthetics, etc. (e. g. only 2D- or only 3D-capabilities) can quickly lead to fallacies of composition. As they so often do in arguments between mostly opinionated men about their favorite toys. :D

I’m usually the first to invoke the “preference isn’t the same as fact” argument, but in this instance we have impartial proof that PCs lagged behind just by virtue of the technology available at comparable price points.

When PCs were stuck with CGA, not support for scrolling, etc, they were unambiguously worse than games consoles of that era. While Atari ST and Amiga were producing graphics that exceeded what the Master System and NES could do.

The whole reason Commander Keen existed was because Carmak (I forget how his name is spelt) found a hack to produce Super Mario quality graphics on commodity IBM-compatible hardware. Something previously considered impossible to do.

The point I’m making about 2.5D games isn’t pretence either. It’s showing where PCs grew beyond the capabilities of their contemporaries. You couldn’t do ray tracing on 16 bit consoles. Frankly, it even performed like shit on most 32bit consoles too. Yet it worked really well on PCs.

What you’re talking about is games that you liked to play. What I’m talking about is the actual technical capabilities of the hardware.

And the fact that literally every single person you’ve chatted to about this has disagreed with your analysis and echoed my statements must surely demonstrate that you’re attempting to rewrite history around your own preferences for PCs.

It’s fine to like prefer PCs. Nobody would criticise you for having that preference. The comments being made here wasn’t that you can’t have a good time with PCs. It was that the technology behind the PCs was shit compared to the other 80s alternatives. And that’s something that you can easily, and everyone already has, clearly demonstrated in our posts.

I think the real crux of the problem here is that you’re too young and/or grew up in the wrong part of Europe to have really seen the difference and instead of listening to others, you’re still firmly clinging onto the belief that your opinions are infallible. Unfortunately, in this specific instance, the body of evidence is overwhelmingly stacked against you.
by namibj | 2025-06-13 21:36:56+00:00
Well, SiC MOSFET do get used, but yeah. SiC JFETs are indeed better, lower lower with the same wafer technology, avalanche proof, high heat proof (the polyimide passivation hurts beyond ~220 C).

Much easier to drive when you stack them for HV.

That said, GaN is there for capacitive converters due to being able to run very efficient at >10 MHz switching frequency.

These converters in principle fit in very compact phase change coolant/insulator vessels, for example with propane. The capacitors at those frequencies get to be tiny, like, smaller than the transistor package by volume.

This was initially my hunch, but after using the betas quite a bit, I changed my mind.

The pre-WWDC rumors suggested that iOS and macOS would be refreshed with inspiration from "Apple Vision Pro." However, after using the interface, I don't see much similarity beyond the use of translucency and some of the toolbar shapes.

I had preconceived notions from watching the WWDC videos before trying the new interface, but I didn't really get it until I used it. The videos don't do it justice and fail to provide a genuine feel for the experience.

Keep in mind that much of what you see in the videos consists of marketing renders.

Note: None of this is to claim that AR isn't going to be a thing. I completely believe it will come to dominate.

I can still remember when they had a sterling reputation (including but not limited to their legendary calculators). Our family had a friend who was an HP engineer and I once got to go to work with him and see one of their giant plotters in action. It was awesome. Now I actively avoid all of their stuff. Not sure I can think of another brand whose reputation has changed so much for the worse.

yeah it was years ahead of apple and android (this was and2.3 days if i recall, or 4.3 which typical google was worse than 2.3)

and the emulator was better dev experience than anything else. but actually putting things on the device that had anything more than js was impossible.

and the hardware was garbage. buttons would stuck. I don't know what sort of museum you live but mines lasted 4 and 2 years before turning to literal bits (used by adults)
by tuveson | 2025-06-13 21:38:38+00:00
Yeah, that's fair enough. I'm sure a lot of weird / bad language design choices can be chalked up to this (COBOL...). Now that C and Pascal derived languages have been around for a long time, even if you don't know about how parsers work, everyone knows that certain syntax / semantics are at least possible since they're the norm, and I suppose that wasn't the case back then.
