Someone shared this piece here a few days ago saying something similar. There’s no reason to believe that any of the experiences are real. Instead they are responding to prompts with what their training data says is reasonable in this context which is sci-fi horror.

Edit: That doesn’t mean this isn’t a cool art installation though. It’s a pretty neat idea.

How is this different from a backdoor in, say, a Thunderbird extension? I've maintained an extension for Thunderbird and, when I was no longer interested in it, a guy pushed hard to take over the project after sending a few legitimate contributions. I declined because it seemed crazy to give the keys to tens of thousands mailbox to a guy I didn't really know. I also found it crazy that people would trust me initially, but well, I know I'm a good guy :-)

Fair concern but I don’t think Auth.js was ever “truly free,” considering it was supported by many companies (big or small) including someone like Clerk even running ads on the docs site.

We started Better Auth with the vision of making high-quality auth (with simple abstractions, great docs, extensive set of features...) and make it accessible to everyone . It didn’t start as a commercial venture, at first it was a purely oss project I created. The reason it evolved into a commercial venture is that we saw new ways to make owning your auth even more accessible and scalable for companies.

The reason we’re bringing Auth.js under Better Auth is that the Auth.js team is moving on, and we don’t want the project to be abandoned, that would hurt trust in open-source auth as a whole. We’ve already seen that happen at smaller scaller with Lucia. If that weren’t the case, we’d actually benefit from Auth.js being deprecated, since we’re effectively the next most people would go for and we wouldn't have to take this risk and responsibilities.

Not at all. A big thrust of the article is about falling behind in AI adoption. See the first 3 paragraphs below the heading "Innovation and Adoption." Specifically:

>"Although the United States and China are very different and the latter’s approach has its limits, China is moving faster at scaling robots in society, and its AI Plus Initiative emphasizes achieving widespread industry-specific adoption by 2027. The government wants AI to essentially become a part of the country’s infrastructure by 2030. China is also investing in AGI, but Beijing’s emphasis is clearly on quickly scaling, integrating, and applying current and near-term AI capabilities."

Yeah, I think what you needed to do here is zoom out. That's a sharply declining chart.

I understand that as a Bluesky user the peak and dropoff doesn't hurt the experience. But investors are going to put money in with the expectation of a return and what they're going to look at are the derivatives of the adoption curve: how quickly is it gaining users, and is adoption accelerating?

To add, as a vinyl enjoyer, it's also that putting on a record is a deliberate action. I'm putting it on with the intent to listen and enjoy it vs. most often when I open up Apple Music it's just background noise while I'm working on other things, where I just hit shuffle on my 10k song+ library. When I put on a record it's because I want to sit with it and listen to that specific album.

Plus there's the aspect of actually owning your media and not simply leasing it with a monthly subscription.

Hey HN We’re working on MedTechAI — a project to help AI/ML folks build better healthcare models without dealing with real patient data. We generate high-quality, privacy-compliant synthetic medical datasets that mimic real-world medical scenarios (but with no actual patient info, so no HIPAA headaches). The data comes in formats like JSON and TXT, and it's designed to be easy to plug into your workflows — whether you're building a medical chatbot, training a model, or just experimenting with healthcare analytics. We’d love your feedback: What would you want in a medical dataset for AI/ML? Any features or formats you think we're missing? Would this be useful for what you’re working on? Open to ideas, suggestions, and collaboration. Happy to answer any questions!

The opamp back in the days were pretty terrible. NE5532 was the king of audio opamp for decades until the early 2000s.

Modern Class D are built on advanced semiconductor processes (they are considered legacy node in the eye of Hacker News's primary audience. They are at least a lot better than the early days in terms of performance in analog domain.) When an IC company spend a lot of R&D money to develop Class D amp, they for sure exhausted what they can do before they tape out. That results in the superbe performance of modern Class D amplifier.

There is still oppertunities in getting analog Class AB type of amplifier working better, such as adding motional feedback control sensor-less or with sensor. KEF recently released a motional feedback soundbar with back-EMF voltage as sensor. It sure improve the sound quality for a soundbar. Although physics is physics, one cannot make a 1 inch speaker sounds like a subwoofer, but motional feedback sure can make 10 speakder sounds like a 15 inch subwoofer.

Sound reproduction is not just a flat frequency response. Perfect reproduction of phase information generates wider 3D sound stage, without the need of DSP to fake it.

A lot of that is predicated on the fact that a CS major in China (and other countries like India, Israel, the CEE) also studied CompArch, OS, and other "low level" disciplines which we in the US don't treat as CS anymore, which leads to a lack of understanding of how to integrate hardware with software.

The fact that DSP is a CSE major requirement abroad, but optional in much of the US aside from ECE programs (but even they have now gated DSP to those ECEs who want to specialize in EE) highlights this issue.

Can't reply so replying here:

> There are lots of young whippersnappers and “old timers” in the “west” who could easily do the Low level make it quick on small hardware stuff

Not to the same degree. The total number of CE graduates (from BS to PhD) is 19k per year in the US.

A large number of those were not introduced to table stakes CS classes like programming language design or theory of computation.

Conversely, for CS major, they are not introduced to intro circuits, digital logic design, DSP, comp arch, and in some cases even OS development because there was a pivot in how CS curricula for undergrads was designed over the past 10 years.

> in the context of adoption as opposed to frontier development.

For real world applications like military applications or dual use technology, frontier development is not relevant. It's important but it's not what wins wars or defines industries.

Being able to develop frontier models but being unable to productionize foundational models from scratch for sub-$2M like Deepseek did despite paying US level salaries highlights a major problem.

And this is the crux of the issue. The best engineers are those who recognize what is "good enough".

Americans who did their undergrad here over the past 10 years act more like "artists" who want to build to perfection irrespective of whether it actually meets tangible needs or is scalable.

> We aren’t actually engineers, we didn’t get to take classes in the engineering college, maybe we should have

Which is the crux of my argument.

CS is an engineering discipline, and some of the best CS undergrad programs in the US like Stanford, Cal, MIT, and UCLA make sure to enforce Engineering requirements for CS majors.

The shift of CS from being a department within a "College of Engineering" to being offered as a BA/BS in the "College of Arts and Sciences" sans engineering requirements is a recentish change from what I've seen.

> Incidentally a lot of AI movers are EEs, not even CSE or CEE.

Yep! Gotta love Information Theory and Optimization Theory. And a major reason I feel requiring a dual-use course like DSP for CS/CE majors is critical.

I came to the same conclusion when upgrading from 18650s to 21700s, I spent a long time trying to weed out the poorly binned rewards, and the minefield of lithium batteries. They weren't cheap but have been happy with their performance.

There are a lot of people out there that see 18650 or 21700 and think a lithium ion battery is a lithium ion battery and they're all the same (i.e. trying to pull 20 amps from a 2 amp peak battery). I miss one of the father's of liion battery education, Mooch (from ecigarettes forum) who had a whole methodology of testing, and educating people.

>if not sure exactly what the problem is but it’s something along the lines of any belief system becomes problematic when it becomes too ubiquitous/dogmatic.

Many qualities are not ruined by universal adoption. Kindness, consideration, empathy, patience and understanding built on the above are some.

> I think the term “toxic masculinity” sort if has three different connotations, for some it’s a weapon ... I do think it’s somewhat time to evolve past the feminism of the past.

The notion that men be better has always been a good one. The core of our toxicity is a failure to understand others in a useful, productive and beneficial way. We men are not very far down the road of understanding others. We have not reached some kind of end that would merit turning back.

The origin of calls to turn back reliably come from the small group that is petulant about making meaningful changes. To transition from a small to a loud group, they are compulsively seeding their discontent wherever they can. We can spot where they've found fertile ground by listening for their echos.

But back to us. There absolutely is room for improvement and the way to get there is by adopting kindness, consideration, empathy, etc. For us men, our ability to achieve these things is tied to our willingness to clean up our own house. We are better men when we have ambition that stretches past our base desires and includes what women decide they want for themselves.

Good stuff, nothing but respect for that kind of work. AMO people are a different breed. Spending all day interpreting power spectral densities and tracking down ground loops takes a certain je-ne-sais-quoi. Literally. Last time I used a microwave amplifier I plugged it in with the wrong polarity and blew it up!

I think we're going to disagree, which is fine, but I'll post the text and let others assess what the meanings of 'nations' is in the context of the quotation.

--

https://biblehub.com/nkjv/matthew/25.htm

31“When the Son of Man comes in His glory, and all the [c]holy angels with Him, then He will sit on the throne of His glory. 32All the nations will be gathered before Him, and He will separate them one from another, as a shepherd divides his sheep from the goats. 33And He will set the sheep on His right hand, but the goats on the left.

[...]

41“Then He will also say to those on the left hand, ‘Depart from Me, you cursed, into the everlasting fire prepared for the devil and his angels: 42for I was hungry and you gave Me no food; I was thirsty and you gave Me no drink; 43I was a stranger and you did not take Me in, naked and you did not clothe Me, sick and in prison and you did not visit Me.’

44“Then they also will answer [d]Him, saying, ‘Lord, when did we see You hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to You?’ 45Then He will answer them, saying, ‘Assuredly, I say to you, inasmuch as you did not do it to one of the least of these, you did not do it to Me.’ 46And these will go away into everlasting punishment, but the righteous into eternal life.”

I've read that going without sleep for just 24 hours is worse for your reaction times than having a blood alcohol content of 0.08, exceeding the legal limit.

Obviously the most responsible choice is to not drive while sleep deprived, or to pull over to a safe location and rest if one is too drowsy to operate a vehicle.

That said, if one is refusing to do that, for whatever reason, I have a hard time believing the upcoming FSD 14 stack is going to be more dangerous than driving drunk, or than driving while so drowsy as to be equally unsafe to driving drunk.

The older pre-NN stacks definitely weren't "there", but it requires either a meaningful ignorance or motivated partisanship to argue that FSD 13 isn't at least approaching the threshold of being a better driver than the worst drivers on the road, if not definitively better.

I’ve been looking for something like this exact form factor but with a giant battery and usb-c displayport out and PD out to use with a pair of video display glasses like the XReal Pros. Could have real space and weight saving potential, better privacy on plane rides, and a nice large virtual display with better ergonomics to go along with it.

I liked this article, but a few things here I think we’re idealized.

“ Unlike a hunter-gatherer group, where an individual member starving would be seen as a collective failure, official capitalist ideology tells you that a person struggling on the street has got nothing directly to do with you, because you don’t really live in ‘a society’. You’re just an individual, free of attachment.”

Sure, maybe some hunter gatherer societies saw it as a failure, or maybe some saw that person as a threat to the community and they got abandoned or shot in the face. We’re just at the scale where instead of having a few of those people every decade we have thousands every year.

Communism has similar failure cases. Sure maybe everyone gets a similar share and no one is “starving” unless your part of the outgroup, or maybe if you’re part of the in in group, you also get extra benefits.

A critical section is code that accesses mutable shared data in a non-atomic way (i.e. as several steps, the classic example is: fetch data into a register, process that data, store the result back into memory). A lock is a mechanism that protects such data by preventing other code (or other threads running the same code) from accessing that data until the critical section completes.

Locks come in several types. A developer picks one type depending on the use of the protected data; for example, exclusive, reader-writer, and others.

Locks are great at preventing data corruption and data loss, but come with issues. They can hurt performance, can cause "liveness" and other issues, and are usually "advisory" ("mandatory" locks which are enforced by the OS are rarely available) so developers must remember to protect data by using locks around every critical section.

Modern hardware includes support for many lock-free mechanisms that can greatly reduce the need for locks.

nonsense. it is time to dismantle the current state of affairs and to start thinking about better ways to approach things. Sure, we can keep all the things rolling as they are. Every once in a while something will flare up in Africa, we send money, we do the work, everything is back to normal a year later, we do it again.

Or maybe we start to question if there is a better way to do things. I don't want to say Trump is doing everything right, but at least he tries. He got the Rwandan president and the Congolese at one table and told them to stop the bullshit.

If Trump ends the war and gets Western countries into the DRC to do proper mining, the DRC will be one of the richest nations of all time, and they will finally have enough resources to educate their population on the dangers of fucking bush meat.

I think I was one of the people desiring a mid range setup, but I found it very hard to justify when the "good enough" is 10-20 times cheaper. Based on perceived value, the $2000 mid range price looks 2-4 times too big for me and there is no sign of adjustment, what you can find at $3-500 is mostly garbage.

Audio is not like a graphics card, but people understand that you can buy at $500 a GPU that is ~ 2 times faster than a $200 one. The low end in audio is tens of dollars and there is nothing good in the hundreds of dollars range.

Canonical rock n' roll in the minds of, "the initiated" might include groups like Kraftwerk and Neu! which laid the foundation for most forms of electronic music. It definitely includes the mother of all electronic music Delia Derbyshire (ask Peter Kember!) You might know her from the original Doctor Who theme music. Dig the link below for the arguably the first EDM song ever made. Keep in mind this is pre-synths-- it's all tape manipulation like The Beatles would end up copying on, "Strawberry Fields Forever."

I like all, "genres" and types of music but there's a certain high level of quality that exists in a continuum of music going back a long time. It's hard to define in a formal way. It's there in John Coltrane. It lives sophomorically in The Velvet Underground, Herman's Hermits, and the other, "Bubblegum" groups as well as the Fuzz-Psych-Garage bands that live in the Nuggets compilations like ? And The Mysterians. It's played on Rickenbacker guitars. It has a fuzz pedal and it knows how to use it. It lived on John Peel's radio program.

Every time I've tried it, from 2007 to now, it's been a buggy hunk of crap. I normally try not to disparage peoples software projects, but I really don't get ReactOS. I tried it again actually just a few weeks ago. It's barely usable. You'll have far fewer problems just using Wine with Linux.
Show HN: Llumen – Lightweight LLM chat app that runs in <1s with OpenRouter
by easonqq0000 | 2025-09-27 16:44:57+00:00
Hey HN, I've been tinkering with self-hosting LLMs and got frustrated with bloated setups needing a dozen API keys for chat, search, OCR, and more. So I built llumen: a dead-simple, full-stack chat web app that gets you chatting with models out-of-the-box.

Why it might interest you: - <b>Effortless Start</b>: Drop in a single OpenRouter API key—no juggling endpoints. Docker image or binaries ready for Linux/Windows (prebuilts on release). - <b>Blazing Fast & Tiny</b>: Boots in under 1s, <100MB disk. - <b>Smart Features</b>: Markdown with code/math rendering, normal chat mode, web-search integration and WIP agentic/deep-research modes. - <b>Opensource</b>: MPL 2.0 licensed. Screenshots and a quick demo GIF in the README to see it in action.

Quick Docker spin-up: <pre><code>docker run -it --rm -e API_KEY="your-key" -p 80:80 -v $(pwd)/data:/data ghcr.io/pinkfuwa/llumen:latest</code></pre>

It's funny to me that in portraying Indiana as a "blank state" he's highlighting one of the most beautiful parts of the state (the route through the Dunes along the Michigan lakefront; if you've seen "Road To Perdition", you know what that area looks like). It's not important to the article, a complete tangent, but I can't not call that out.

The thing called Launchpad was removed, but its shortcuts still exist and take you into Spotlight's (new) applications panel. This gives you the searchable-list-of-apps that Launchpad offered, though it doesn't let you rearrange them... so depending on how you personally liked to use Launchpad it'll either be a perfect substitute or incredibly frustrating for you.

Yeah I thought the same thing. This has nothing to do with MCP really, the same flaw is there in all software: you have to trust the author and the distributor. Nothing stops Microsoft from copying all your Outlook mail. Nothing stops Google from copying all your gmail. Nothing stops the Mutt project from copying all your email. Open source users like to think that "many eyes" keep the code clean and they probably do help, especially on popular projects where all commits get reviewed in detail, but the chance is still there. And the rest of us just trust the developers. This problem is as old as software.

Maybe the problem is with our funding model. Necessarily the whole grant system is based on being able to argue a narrative as to why your scientific inquiry deserves money. Combine that with a system that includes incentives towards or away from social values, and scientists are necessarily activists.

And then that’s just to get money in your specific direction, getting money in your general direction requires more broad activism.

Is there a way to configure the jump (hop) server to reroute the request based on the value of %h and/or %p? Otherwise, it's going to be quite difficult to configure something like HTTP virtual hosts.

EDIT: Looking at the relevant RFC [1] and the OpenSSH sshd_config manual [2], it looks like the answer is that the protocol supports having the jump server decide what to do with the host/port information, but the OpenSSH server software doesn't present any relevant configuration knobs.

> Not that linux was even remotely close to being usable even only twenty years ago.

Running Linux on regular consumer hardware in 2005 was not really any harder than it is today. In fact, many of the same problems still exist! GPU drivers and janky wifi and power-saving modes, same shit, different decade.

There's Steam Deck now, and Android, but those are still quite proprietary driven by single companies, so I'm not really sure they fit what you mean about an open alternative.
