There’s an analog analogue: mixing and mastering audio recordings for the devices of the era.

I first heard about this when reading an article or book about Jimi Hendrix making choices based on what the output sounded like on AM radio. Contrast that with the contemporary recordings of The Beatles, in which George Martin was oriented toward what sounded best in the studio and home hi-fi (which was pretty amazing if you could afford decent German and Japanese components).

Even today, after digital transfers and remasters and high-end speakers and headphones, Hendrix’s late 60s studio recordings don’t hold a candle anything the Beatles did from Revolver on.
Show HN: Built a portable memory layer that works across AI tools
by hirasiddiqui247 | 2025-11-11 13:46:49+00:00
Hey HN, I've been frustrated that every time I switch AI tools (ChatGPT, Claude, Gemini, etc.), I lose all context about my preferences, projects, and past conversations. So I built a portable memory system that maintains context across different AI platforms. This became the #1 product of the day on product hunt How it works: A browser extension that lets you store highlights, conversations, file uploads etc. and then adds inline context to any of your query on any agent

Current state: - Works with all major AI platforms (ChatGPT, Claude, Grok, Gemini, Perplexity etc.). - Can create n different contexts and select which one you want to use when - implementing TEEs on the backend for privacy

What I'm unsure about: I'm trying to figure out if this is actually valuable enough for people to pay for, or if it's just solving my own niche problem. Questions for this community:

Do you find context-switching between AI tools painful enough to pay to solve it? What would make you trust a third-party service with your AI conversation context? Is this something you'd expect to be free, or does $12/month seem reasonable?

Would love honest feedback - especially if you think this is a terrible idea or I'm missing something obvious.

There are countries where drug consumption/posesion is penalized too. There is a similar example in other area: For instance, in Sweeden, Norway and Belize selling sex (aka prostitution) is legal, but buying it is not legal. So, your example actually exists in world legislation.

I'm just asking where are we going to put the line and why.

There are two of us! I also espouse the virtues of TortiseGit any time I am able! I do take a bit of guff at work, but one feature of TG I've never seen equalled is how it handles what I call "drill-down git blame adventures". TG'a blame lets you easily keep going down through a files commit history in a way that is both intuitive and useful. My only issue with TG is that it is so Windows-focus and as I'm working more and more in Linux I will tragically need to leave it behind ;_;

I have not heard or read anything about AI that could be construed as positive for an ordinary person. Step one is "lose your job with no possibility of finding another one, but still have to buy stuff to survive." That will also be the last step for a huge number of people. Is there a bull case for some hypothetical regular person with a desk job? I haven't seen one.

Could not agree more.

As a child in the 80s I read a programming book (can't remember the name anymore unfortunately) where the reader was encouraged to write software that is always friendly and human when it comes to communicating with the user. For example, 'Please input a number:' instead of 'Input a number:'. But also exactly the thing the writer talks about in the article; do not be lazy when it comes to pluralization.

I get nostalgic remembering that era in computing.

> She doesn't need to have any expertise

By living in a bubble, she became less knowledgeable on common matters than an average citizen, and this even extends to her cabinet.

The proof at hand is the story of her "GPS-jammed" landing in Plovdiv.

She lied, her press secretary lied and there was none around to tell them about ADS-B, FlightRadar24 and how these lies can be trivially verified.

> Imagine you are the CEO of Apple.

Alright. Since when have I been CEO? Was I nominated today? Then I can definitely stall for a good while as I’m getting acquainted with everyone and the inner workings of the company, and come up with a plan.

Was I nominated a decade ago? Then Apple looks very different from today and I wouldn’t be in this situation because I wouldn’t have my supply chain almost entirely dependent on an authoritarian regime.

Again, the problem with Tim Cook is the pattern. Don’t narrow your mind to one specific case and shrug your shoulders as if there isn’t a choice, look at the big picture. This isn’t one isolated case, this is only one instance which came about from decades of decisions.

The problem was "have documents that look the same on any device, including printed paper and computer screens", and the approach was "PostScript does that for printers, let's simplify it and make it more universal". Both the problem it's solving and the approach were fine, maybe even great. Since then over three decades have passed, pdf has gained a plethora of features, some less well thought out than others, and real-world requirements are completely different than they were in the early 90s. If we were to invent pdf today it would likely look completely different. But it's still good enough that it's hard for a new format to offer an advantage compelling enough to replace pdf.

What I personally find amusing is this part:

>3. Interactive: World models can output the next states based on input actions

>Finally, if actions and/or goals are part of the prompt to a world model, its outputs must include the next state of the world, represented either implicitly or explicitly. When given only an action with or without a goal state as the input, the world model should produce an output consistent with the world’s previous state, the intended goal state if any, and its semantic meanings, physical laws, and dynamical behaviors. As spatially intelligent world models become more powerful and robust in their reasoning and generation capabilities, it is conceivable that in the case of a given goal, the world models themselves would be able to predict not only the next state of the world, but also the next actions based on the new state.

That's literally just an RNN (not a transformer). An RNN takes a previous state and an input and produces a new state. If you add a controller on top, it is called model predictive control. The most extreme form I have seen is temporal difference model predictive control (TD-MPC). [0]

Not for me. Exccessive customer obsession puts me off as customer. Don't try to read too much into me. Don't try to sell too much. Don't try to please me too much. Don't think about me too much.

Instead, think about the stuff you are offering. Treat it as if you are building it for yourself, and not for selling. Build it the way your like most. Sound as if you don't care about selling. Be proud of it. Get off of the sales pitch and pleasing talk.

Stay equal with your customer regarding who should please whom. It's an exchange of value between equals. No need of one pleasing the other too much. Customer need not have the upper hand. They should be just as desperate to buy, as you are for selling.

If selling is seen as a win for the seller, then it should always be a loss for the buyer, which is not true. Once you stop seeing it as win, you will stop this overreaction.

I'm a full-time professional musician, and I don't know anybody (at least in bluegrass) who thinks that the system of IP is designed to protect us, or is in fact serving us in economic terms. It seems much more geared to protect spotify and apple than it does the musicians.

Last year, I cut Drowsy Maggie with David Grier (something about which I boast every chance I get :-) ), and part of our journey was listening to aging, nearly-forgotten versions to find melodic and harmonic ideas to harvest and revive. For this, we of course made heavy use of archive.org's Great 78 project - and at the very same time, the RIAA (who is supposed to represent us?!) was waging aggressive lawfare against the Great 78 project, to try to take it down.

It was just the height of absurdity.

Consider that since at least 2020, every grammy winner in both the bluegrass and americana categories (and almost no nominee) has been released DRM-free. And that many of the up-and-coming bluegrass and jam bands are now releasing all of their shows, directly off the board, licensed with creative commons-compatible licenses.

Show HN: The Product Sandbox – Practice real-world product challenges

Hi HN,

After 15 years in product management, I realized there’s nowhere for Product Managers to actually practice, most learning focuses on theory, not doing.

I built The Product Sandbox, a platform where PMs can practice real-world product scenarios, make decisions, and strengthen core skills through daily missions and challenges. It’s designed for aspiring to senior PMs who want to keep improving through real practice.

I’d love feedback from this community on how you think PMs (or teams) can best build real-world experience outside of their day jobs.

You seem to be suggesting that current frontier models are only trained on text and not "sensor data". Multi-modal models are trained on the entire internet + vast amounts of synthetic data. Images and videos are key inputs. Camera sensors are capable of capturing much more "sensor data" than the human eye. Neural networks are the worst way to model intelligence, except all other models.

I’d like to think I do pluralization right, but sometimes it’s just that bit too time consuming because of an awkward internationalization issue or something so I don’t. There’s only so much polishing you can (or should) do before you ship. If I found that my team suddenly had a lot of time for cleaning up this kind of thing, I’d start worrying about job security tbh.

I can understand why this may seem simple, but when it comes to the brain almost nothing is simple.

Choline a key component in Acetylcholine is the primary neurotransmitter used in your hippocampus. Its an excitatory neurotransmitter meaning it turns neurons on. The hippocampus is a massive parallel feedback circuit that when over stimulated can and will begin to seize. In fact many people who suffer from seizures have over active hippocampal circuitry. Simply "flooding" the brain with more choline could have very very bad effects.

Likewise, taking choline might not work as the brain actively controls and regulates the contents of the cerebral spinal fluid. Unlike the rest of your body, the capillaries in the brain are not leaky, but instead are enshrouded in the blood-brain barrier and there are active transport proteins for anything that isn't lipid soluble.

Choline is actively transported into the brain and the brain has additional internal mechanisms to regulate the levels of choline.

Lastly, neurotransmitters aren't just floating around in the soup of your brain. They are released by specific neurons which are integrated into specific circuits. Parkinson's disease is a perfect example here. There is tiny region of the brain involved in regulating voluntary movements that is rich in dopamine neurons. For Parkinson's these neurons die off while the rest of the brain remains relatively strong. Simply putting dopamine into the brain doesn't fix the issue you need to up the dopamine released by these specific neurons.

The treatment here is l-dopa which is a precursor to dopamine which does this, but once those neurons are gone they're gone and there is little we can do to stop the disease.

So if this works for l-dopa why won't it work for choline? My guess is because of the tight regulation the brain has around choline levels as its needed to prevent the hippocampus from seizing up.

But that’s what people do - they would wine and dine some low level employees to get inside info.

You want to know when how much shit new GTA developers take by managers pressing them on deadlines - guy doesn’t have to spell it out he just needs to nag a bit here and there while having a beer.

Then you can know if they are not pressing them all goes smooth and they really will release when they want - if they are pressed much most likely product is in shambles and they most likely will not hit any targets or promises.

My first-hand experience of the healthcare system in the USA leads me to conclude we don’t have good data on pathological anxiety levels. Psychiatry is over-incentivized to positively diagnose.

You can get diagnosed with ‘anxiety’ when you’ve been in a hard circumstance for a while, since it’s simply a self-reporting questionnaire on levels of concern. That’s not a way to determine pathology - how do they tell when it’s appropriate behavior, eg when you’re actually in a dangerous situation.

This economy, since the financial crisis, has had weak employment (when you factor in not-in-workforce trends over the last 50 years), being under-employed for a long time is a threat to life. You can be in a location or situation where you’re blind to a loss of economic opportunity because there is so much misinformation. Anxiety is not maladaptive then.

This happened to me, and when my situation finally began to improve after a change in direction, my anxiety went down. Before I made that change, I found anti-anxiety meds put me in a dysfunctional ‘happy’ state, that made it harder to course correct or care about my reality. So I quickly stopped taking them last year, shortly after receiving them. And yet a diagnosis was made then, and looking at my medical report, this so called disease remains on my medical record. Ridiculous. All that self-reporting showed was normal human behavior.

Luckily, at the worst time, I also hedged by seeing separately a psychologist who helped me understand through a series of interviews that all my behavior was appropriate to my situation.

What exactly isn't working for you? The last two/three months I've been almost exclusively doing ML work (+CUDA) with a NVIDIA card on Linux, and everything seems to work out of the box, including debugging/introspection tools and everything else I've tried. As an extra plus, everything runs much faster on Linux than the very same hardware and software does on Windows.

Preventing memory leaks isn't normally what people mean by "memory safety".

As an aside: a common memory management approach used in Zig is to have a dedicated memory pool for an operation and simply free all of the memory after the operation is over instead of freeing individual allocations.

For what it's worth, I'm stuck on the very first x = x + 1 thing.

Not sure if you want to call it a screwup or bad grammar or whatnot, but it is perhaps the huge mistake that the "equals" sign was used for something that feels like, but emphatically DOES NOT mean, "is equal to."

It's "put this into that". It's an action verb. Should have perhaps insisted on x <- x + 1 or maybe better x + 1 -> x

To put this in perspective: world wide the emissions were ~ 37.8 billion tonnes (gigatonnes) in 2024 and 4.77 billion tonnes in the US. So, we're talking about 0.019 % of US emissions.

That's not nothing but also not that high relative to some other things. Addressing this is not going to do much to solve the overall problem that the US is emitting a lot of CO2. AI usage is probably going to grow over time. But it will have to grow a lot to get to displace e.g. transport, industrial heating, or agriculture as dominant sources of CO2 emissions.

Short term the tendency of AI data center providers to solve their energy needs with gas powered generation (mainly) is not great of course. It's opportunistic, there's extra underused gas generation capacity currently that's more or less readily available.

But long term there are some obvious cost savings there as well. Gas isn't cheap; even in the US. And gas turbines are actually scarce. Increased demand is hard to meet with just gas for this reason. AI data centers aren't picking the cheapest energy source but the easiest accessible energy source. Some companies are even looking at nuclear. And not because it's cheap. Likewise, some companies are apparently considering doing some AI compute in space (solar powered).

Long term, solar, wind, and batteries are likely to be the cheapest way to source energy in this sector as well as is already the case in other sectors. Energy is one of the largest cost components for providing AI compute and competition is likely to be fierce. There's no way that companies dependent on expensive forms of energy will be able to compete long term. The short term game is about grabbing market share. Surviving long term will require aggressive cost savings on energy generation.

Is it good for society to disable traffic cameras? Here in Sweden, traffic camera is used exclusively to reduce traffic speed on roads where the maximum speed is too fast for installing traffic bumps, with an expected effect of reducing traffic speed by around 20-30%. They are generally only installed on 60-90km/h roads, around road maintenance/construction sites, and in tunnels. They active when the radar detects speeds of 5km above the maximum. (The reduction in speed happens regardless if the camera is functional or not, since it is primarily a psychological effect).

Sweden also have traffic monitors that monitor highways around cities, border exists and tunnels, and also license plate readers for toll roads and bridges (also often used for parking). Those two generally have a much higher privacy cost than traffic cameras.

This is the brown m&m theory. https://www.smithsonianmag.com/arts-culture/why-did-van-hale...

A trivial, superficial fact is assumed to be indicative of a much more substantial concern. For Van Halen, the candy dish indicated adherence to contract terms; here, pluralization indicates the integrity and values of an entire company.

It’s a cute idea that suggests an easy way to understand something complex. But there’s no free lunch. If you want a free lunch, you’re asking to be taken for a ride.
