Show HN: BetterBrain – Dementia prevention, covered by insurance
by adi4213 | 2025-10-03 02:03:05+00:00
Hey all! I’ve been building BetterBrain for the past few months, which is the first dementia prevention program entirely covered by insurance. BetterBrain combines expert clinicians, comprehensive testing and state of the art AI - and for many insurance plans is $0. Research shows that dementia can be detected up to 20 years in advance. Despite this, many people at risk of dementia overlook regular brain health assessments. Many members of our founding team have family members affected by neurodegenerative disease.

We’re also hiring aggressively if anyone is interested in changing the future of treating neurodegenerative disease.

Would love to talk to anyone interested https://www.betterbrain.com/insurance

My push-up story: I used to think I can easily do many pushups until I met my personal trainer and did push-ups in front of him. In his opinion, none of my pushups were correct. It was discouraging to hear someone dissect my mistakes: elbows flaring out instead of being held close to the body, hand position too wide or too forward, hips dropping. Of these, fixing the last mistake of hips dropping seemed the most elusive. Some days I could control the hips perfectly well, but other times I seemed to be unable to control the movement of the hips.

I still do 50 pushups per week with a mix of good and bad form (which is of course way less than 10k per year), but I found that I've mentally associated pushups with an exercise that I couldn't do well. It doesn't give me any dopamine boost. I'm much happier doing something else like barbell squats which I could do with good form and increasing weights.

You've chosen a number there, conveniently lower than the one the Israelis picked. I must say, an argument that convenient is not persuasive.

To address it properly we must start with whether anything above zero is "acceptable" (in the sense of a level that would accord with the realities of increased food insecurity in a war zone, not morally).

If it is, then a level needs to be set, and if the level is met then I would expect the parties in question to argue about it, if only because of the propaganda value, let alone the truth of the claim.

The claims about mistakes in the data, or presentation of the data, are here[1], I am unable to tell if they are right or not, but that is not the point of this conversation. The point is, whether their should be stages at all, and if so, should the results of reports be scrutinised?

I would say yes to both.

Most people don't get blocks nowadays for cataract surgery. I will do so for patients with wandering eye movements or for more difficult cases, or for more invasive surgery besides cataract surgery. I just did a cataract surgery on a young patient today using topical numbing drops. But I have them monitored by an anesthetist with mild sedation during the entire case.

> but about instruction fusion in general in any ISA with a memory model at least as strong as RVWMO -- which includes x86

No... It's kind of an artefact of RISC-V's memory model being weak. x86 side-steps the issue because it insists that stores always occur in program order, allowing it to fuse away conditional branches without issue.

(Note: the actual hardware implementation of x86 cpus issues the stores anyway, and then rewinds if it later detects a memory ordering violation)

RISC-V ran into this corner case because it wanted the best of both worlds: A Weak memory model, but still have strong ordering across branches.

Looks like ARM avoided this issue because its memory model is weaker, branches don't force any ordering, which means the arm compiler might need to insert a few extra memory barrier instructions.

---------

TBH, I don't think this fusing instructions edge case is a big deal. For smaller RISC-V cores, you aren't reordering memory operations in the first place.

And for larger RISC-V cores, you already need a complex mechanism for dealing with store order violationss, so you just throw your fused come instruction at it. Your core already needs to deal with sync points that aren't proper branches, because non-taken branches also enforce ordering.

> I think that Apple is a company that has to obey the rule of law.

Right, so the fundamental problem is having a device where the software that runs on it is controlled by a single company. It creates the attractive nuisance of being able to choke off anything the government doesn't like because, as you said, that single point of contact can't avoid obeying the government.

Computing needs to be open and controlled only by each individual owner of each device, so anyone can run whatever they like sourced from wherever they like.

How does that play out for languages that use characters that are pictorial.

eg. Egyptian Heiroglyphs, or Asian characters (esp. Korean which has a relatively young alphabet - which IIRC is phoneme based, or Chinese which has a very old set, which is used across multiple languages (eg. Mandarin/Cantonese/etc)

> MIG virtualization is IMHO weak sauce.

I know several HPC sites that use it: they (e.g.) ordered cookie-cutter server designs/models to simplify logistics, but not all of their users need the complete capabilities, and so they slice/dice some portion into smaller instances for smaller jobs.

E.g.:

* https://hpc.njit.edu/MIG/

* https://www.rc.virginia.edu/2025/07/hpc-maintenance-aug-12-2...

> Only seven slices. Seven?

At some point the slices because so small that they stop being useful. An A100 can have as 'little' as 40G of memory, and you're now down to 5G per instance:

* https://docs.nvidia.com/datacenter/tesla/mig-user-guide/#a10...

> Extremely limited hardware support.

It's a reasonable argument that you'd only need it at the top-end of the hardware: the number of workloads that need all that compute and memory are not that common, so downshifting some hardware to resource slices that are more typical is not crazy. Of course you then upshift when needed: but if you had purchased 'smaller' cards because that's what you thought you (initially) needed, then you're stuck at that level. There's no way for you to upshift/de-downshift.

> Difficult to configure - like the early days of CUDA.

How hard is it to run nvidia-smi?

> Meanwhile, don’t forget that if your workloads are cooperative, you can put all the processes you want on a single GPU and they’ll happily multitask. No security boundary of course, but who knows how good MIG is at that.

The security boundary of MIG is lot better than MPS, which basically has no security. I know several folks running HPC clusters that use it to isolate the Slurm workloads of different users. And my search-fu has found no CVEs or published papers jailbreaking out of MIG instances.

> I’d greatly prefer better tools for cooperative GPU sharing like per process memory limits or compute priority levels. Also seems like it should be way easier to implement.

This is what MPS is for:

If you look up these words in the dictionary, the same word with the same spelling very often has several different definitions that are often unrelated because homographs (same spelling, but different meaning) are super-common in English. Dictionaries don't account for newer or more niche meanings of words either.

How is it that you can say these words without confusion?

Language is context sensitive and you understand the word based on the context around it. Likewise, you understand homographs based on the context. Because of this, spelling isn't as important as it might appear.

> to remove an app that allowed people to evade law enforcement.

No, they continued to allow police location apps (Google maps will even tell you where they are).

The language they added to the app store rules were very specific: "Apps may only display DUI checkpoints that are published by law enforcement agencies, and should never encourage drunk driving or other reckless behavior such as excessive speed."

Whether or not that was a good idea at the time (it wasn't), you can't claim this is covered by the same guidelines.

I'm not saying this isn't happening, the fact that the RSNs are (mostly?) owned by betting companies does not help.

But, anecdotally, my local (Angels) broadcasts don't talk about it at all. I listen to MLB Radio, and their day time shows barely touch on it (I'm pretty sure there's a odds making show on the radio, but not during prime time in the day).

MLB Network on TV, I do not see it in their main shows. MLB Central doesn't (I don't think, I'm honestly not a regular viewer) really touch on it. MLB Now doesn't, nor does MLB Tonight or Quick Pitch (their overnight highlight show).

There's ads, there's ads in the stadium (big BET MGM sign in Yankee stadium, for example).

So, anyway, on the periphery, it's certainly there, but the shows the MLB seems to put their brand on, I'm not seeing that much of it.

The closest I've see is on the Apple TV broadcasts where they might put up a "28% chance to get on base" in the corner for a batter. Interesting, perhaps, statistic, but I don't know that it necessarily encourages betting.

I participated in the first cohort and I'll be doing it again because I enjoyed it so much the first time around. The course focuses on teaching a robust problem solving approach, rather than explicitly teaching people how to program with AI. It's not a dream or a scam! If you digest the course concepts, the takeaways can be put into practice even if you aren't programming directly in SolveIt. But the SolveIt application certainly greases the wheels by making this problem-solving approach easier and fun! My growth as a programmer has been supercharged by what I learned and applied in the past year since taking the first course.
Show HN: Pluqqy – Terminal based context management tool for AI coding
by tortilla | 2025-10-03 02:08:20+00:00
I vibe-coded a terminal tool called Pluqqy (I had a dormant domain on hand) to help me keep LLM context organized while coding with AI. It’s my first time writing Go and my first terminal app, built almost entirely with Claude Code.

• What it does: Pluqqy lets you manage prompts, rules, and context as small building blocks, then stitch them together into a single file (like AGENT.md or CLAUDE.md) that your coding agent can consume. It’s meant to reduce context drift and make iteration easier.

• Why I built it: I was losing track of my agent context between sessions and wanted something lightweight, reproducible, and terminal-native.

• Status: This is more of an experiment / thought-tool than a maintained project. It works on Mac; Windows/Linux haven’t been tested much.

• Install: go install github.com/pluqqy/pluqqy-terminal/cmd/pluqqy@latest

• Landing page: https://pluqqy.com (just had fun with it)

I'm not 100% sure, but I think this tool just types the commands. So it avoids typos and you can just focus on what you're saying as you type nonsense. Sounds like it actually does run your pre-written commands. From the readme:

> What's more, It's a Live is actually running the commands you're typing, so you have full interoperability with other programs.

Yes, the original policy in the UK was for separate schools rather than advanced classes - the equivalent policy for advanced classes was (is?) known as "streaming". I don't know of any charter schools which are for-profit (funding state students attendance at fee-paying schools was eliminated at some point in the 90s I believe also), but the nearest equivalent would be a "free school" which must be a non-profit.

"What we have seen throughout this is not criticism. It is hate. It is often directed at Jews, not just at the Israeli government. Not 100% but a large percentage."

This is exactly the blackpill. I live in a Muslim-majority country. Jews and Muslims have been allies since the start of Islamic history. Yes, there was some hate for Jews 20 years ago, but it has been gradually displaced into Zionist hate.

The recent analogy is Imperial Japan. The Japanese killed, raped, starved our people. But it was specifically the Imperial Japanese, not the citizens. Firebombing citizens didn't make anything better and it only slowed the process of post-war healing. We have great relationships with Germans and Japanese today despite their past. Moving on is an option.

Some of it is because we see the same pattern. Nationalist politics will always say, "Everyone hates you. We are the only ones who will protect you." For the former British territories, it was the playbook.

I do believe the only way to break from this cycle is to break this hold. Internally: don't keep genocidal leaders in power. Externally: avoid all this racist shit that gives fascists their power base.

The point is that if you could install the app by side loading it, or from a third party app store, then a Government order to remove an app doesn't make it impossible to use that app. But Apples actions, ostensibly to protect its users, but in reality to protect its profits, has put it in a situation where it is a much more effective tool for government censorship.

The biggest thing when teaching someone to use an iPhone - do NOT assume they need to know all the things YOU know how to do.

Instead, ask them what they want to be able to do, and show just that. The temptation is to show too many things.

Also, you can still configure an iPhone with no passcode, which is honestly the way to go, probably.

The difference is scale.

Humans can be reckless, but the scale is so unbelievably small that's its not a big problem.

Like, you can't accidently do the Holocaust. Because that requires deliberate coordination of millions of people.

Can AI accidently do the Holocaust? Yeah, probably. Its software, it can duplicate itself infinitely.

I like how you start with "myopic view" the tell me to use my "big boy brain" to see the ease of creation across the board going down as a negative thing.

The purpose of the society was never to pay money to people, and if we figure out how to get grains of sand to replace skilled labor, there's no amount of greed that can outpace what it will do for humanity.

The iPhone - and macOS too - used to be a paragon of simplicity.

Today the setup experience on a brand-new iPhone or Mac is abysmal. Entering the same username and password multiple times - then sometimes a different username and password - competing notifications, irrelevant feature nags, a popup from some random product manager about their pet thingy. Permission questions from some meddlesome privacy team about the feature you just said you wanted to turn on. Uncertainty about whether you’ll break something irreparably by “skipping” the expected setup path. A choice of several inscrutable interface modes because no one has the balls to commit to a single solution. Just terrible.

I guess this is what happens without a dictator to tell people they’re fired for shipping garbage, and when a company worries about meeting quarterly KPIs rather than doing something great.

your entire narrative screams “I’m the victim here, please validate my aggressions, abuses and violence”.

the state of Israel has not been respectful since day one of it’s inception (violating the defined borders) neither truly wants a two state solution.

this outcome is the product of what escalated from that.

at least you understand the correlation between a figure like Trump and the state of Israel, that’s exactly on point.

it’s ok when one side violates borders and even settles on foreign land but when reactionary action (you’ve helped shape) takes place, you’re now the victim…

Me neither and I share your concern. That being said it's my opinion this popularity is propped up by algorithms that tend to push people towards this type of dumb shit. If there was a way to get through to these misguided idiots I think this country may have a shot at not being a complete hellhole. Is it idealistic and naive? Maybe. Just my two cents y'know.

I empathize. My dad is 98 and can mostly use his iPhone fine, but I just wish I could turn off all the “shortcuts”: He doesn’t get swiping down from different edges of the screen for control panel vs notifications. He doesn’t get hard-pressing on icons for different options (like the flashlight), and so on. Wish I could turn off Siri and Apple Pay, because hitting the “sleep” button just slightly wrong can invoke them and then he’s stumped.

We tried to get my grandma to use an iPad (not my idea), she ended up locking it in a drawer because she got upset with it. I can't blame her.

Ultimately, I don't think it's to her detriment. There would be some ease of mind if she had a cell phone and were comfortable using it (over a home phone) but tech is not for everyone.

There is no one optimal planning horizon. If you have a small team and rapid requirements flux then you might not be able to plan more than a day ahead. But if you're trying to coordinate a huge program with a geographically distributed team, multiple suppliers, hardware components, regulatory compliance issues, etc. then you might have to plan even more than a quarter ahead to avoid complete paralysis.

One of the things I’ve noticed with senior people is that fine motor control tends to start to go,

Things like double click a mouse is difficult to perform two very fast clicks, without also moving the mouse,

Same with iPhone, swiping without deviating, pressing TINY buttons, and even what constitutes a tap are difficult for the elderly. Yes there’s zoom but that only makes it 10% better, as I watch them

Like it or not, Google has wormed their way into the fabric of modern life.

Chrome and Google Search are still the gateway to the internet outside China. Android has over 75% market share of all mobile(!). YouTube is somewhat uniquely the video internet with Instagram and Tiktok not really occupying the same mindshare for "search" and long form.

People can say they don't "trust" Google but the fact is that if the world didn't trust Google, it never would have gotten to where it is and it would quickly unravel from here.

Older/earlier iOS was more simple, intuitive, and usable from my point of view (mid 30s tech oriented male). Now even i find myself getting lost in the endless settings menus and too many different home screen / option screen / extra screens. I don't even use MacOS Launchpad. Just give me a desktop, window manager, and simple notifications.

I dread the day my older mom updates her iOS and calls me for help.

So you don't know what vibe coding is.

The comments I replied to cover it quite well:

> Very interesting observation. I haven’t written a function by hand in 18 months.

> Same. I haven't written any code by hand in some time. Oh well. I guess I'm just doing it wrong.

Using LLMs to help doesn't make it vibe coding: these are people claiming they write no code at all and only prompt agents.

You can't build a complex product with good UX/UI this way... but you can generate Tailwind slop.

What is OpenAI's competitive moat? There's no product stickiness here.

What prevents people from just using Google, who can build AI stuff into their existing massive search/ads/video/email/browser infrastructure?

Normal, non-technical users can't tell the difference between these models at all, so their usage numbers are highly dependent on marketing. Google has massive distribution with world-wide brands that people already know, trust, and pay for, especially in enterprise.

Google doesn't have to go to the private markets to raise capital, they can spend as much of their own money as they like to market the living hell out of this stuff, just like they did with Chrome. The clock is running on OpenAI. At some point OpenAI's investors are going to want their money back.

I'm not saying Google is going to win, but if I had to bet on which company's money runs out faster, I'm not betting against Google.
by maxglute | 2025-10-03 02:15:11+00:00
Big tech are bigger than ever, they've simply learned to double dip with pay to play and ads. AI is also going to do both, but I think they have stickiness to extract a lot more per month. Like once a generation grows up with AI crutch, they will shell out $$$ to not write their own emails, for the simple fact that they never really learned to write all their own shit in the first place.

>You're fired is just words, your health insurance is denied is just words, we don't accept your type here is words, you're being sued by someone with effectively infinite means is just words. But those words that will drastically change the course of your life.

None of these is "just words" lol. The words just convey something that will or won't be done. All of these examples are overly dramatic too. I too wish I lived in a world where nobody could tell me "no" but that'll never happen. If someone has lots of money and you don't, they probably won't sue you. Especially for a petty reason. There's not enough to gain from that.

>While I abhor physical violence, I do also realize some words are also a type of violence in and of themselves.

Violence is physical. People are only trying to claim a connection because they want to censor their enemies using one of the exceptions to free speech, which is when there is threat of imminent violence. As nasty or unpleasant as words may be, they bear no resemblence to actual violence. And no, you don't get to censor people because they say stuff that you feel bad about. The whole point of free speech is to allow the expression of unpopular and unpleasant words. Please get your language right and stop trying to gaslight the rest of us into a censorship program. Thank you for your attention to this matter lol

Well, you can remove the Windows spotlight stuff from the lock screen through the regular settings. Change it from Windows Spotlight to picture or whatever, and remove "Weather and more" from the "show detailed status". I'd say the ability to disable that through Group Policy stretches the definition of "important feature"

I'm not sure I'd agree those policies are enough to truly argue Windows 7 was a last version to not separate out important features to Enterprise -- I'd actually instead simply make the larger point that before Windows 10, Windows wasn't a chintzy ad-driven whorehouse.

I taught my now 83 year old mother to use an Android phone 10+ years ago and now I use Nova Launcher to do my best to emulate the experience she's used to every time there is an OS update. She does pretty well, but recently Google changed the default Phone app and she hates it. It's tricky keeping the experience stable once they have learned it. There are also several "senior" launchers meant to simply the UI but all of them have been a little too restrictive.
