Show HN: The AI App I Made for My Wife Became Everyone's 'Digital Painkiller'
Sometimes love inspires innovation, and sometimes the best solutions come from real pain points. Here's my story.

It All Started with a "Pain"
My wife is a dedicated teacher who supervises student internships. Every week, she manually typed hundreds of handwritten addresses into Maps. Every. Single. Week.

One evening at our kitchen table, surrounded by papers, with tired eyes, she sighed, "There has to be a better way."

Right then, I realized I had a similar "pain" - as a developer, I was constantly lost among code screenshots, manually retyping each one... Two different pains, same root problem.

Not Just Our Pain, Everyone's Problem
As we shared our solution, we discovered everyone has similar "digital pains":

For Teachers:

The struggle of digitizing handwritten student assignments

The hassle of entering hundreds of addresses into maps

The challenge of preparing exam questions

For Developers:

The pain of retyping code from screenshots

Gallery chaos

Documentation creation headaches

For Students:

The struggle of digitizing lecture notes

The hassle of copying book pages

The challenge of creating study questions

For Business People:

Piles of business cards

Meeting notes chaos

Document archiving struggles

You can’t help but thinking the design process was just a bunch of completely random sketches accompanied with a story.
Someone recorded a few car journeys and put them on Mapillary.

Here is one that anyone interested can check out.

Probably the closest thing to a Street View that we will get from there for a while.

how fast do these machineries move?
as I understand the weather scenario the wind direction was changing rapidly by more than 90 degrees at hurricane level.
That means, the boat was unable even under power to redirect into the wind timely enough.
The key question is, how much side wind can the design withstand without getting pressed into more than 45 degrees.

obviously lowering the keel affects this a lot, as there is much difference in leveraged 60 tons vs non-leveraged.
Sure race conditions in general, but the subtlety that it can cause memory unsafety, not something I recall being mentioned.
In the study they use Mankai Duckweed, which is a proprietary strand of Duckweed that is no longer sold to consumers as of 2022 or so. The corporate website still has an intake form for distributors and restaurants/businesses.

Studies that use proprietary plants are always suspicious to me.
> fat was demonised in the 1960s(?)

Still nowadays. Docs still learn about LDL and HDL like it says something about your future cardiovascular risks and tell you to control your diet to avoid fat. The original study on this is full of flaws.
I'm always surprised that people see multilayered identities as something that you have to divide into first and second or prioritise among them.

In a smaller context: Being German and NRW'ler and in the Ruhr area are not a hierarchy. I don't have to choose between them. Similar to European: Although I'm not well-off, it's just part of the pudding.

In Computer terms: Identities seem for me less that a directory hierarchy, more like labels or tags.

No, they have their own data sources for Czech Republic and they are very thorough.
Our S7 basically went into a shutdown sequence every time we'd try to run it. After disassembling it and replacing the serviceable parts, I can only assume it was something with the logic board. I assume after enough troubleshooting and parts, I presume I could have fixed it, but I threw in the towel and replaced it with a Roborock.
So low sugar to slow down brain aging and low protein to slow down body aging https://www.thelancet.com/journals/ebiom/article/PIIS2352-39...

They add a lot more than sugar as preservative nowadays. Good luck finding something without preservatives sold in stores.
They could get fully operating machines and that's not enough to make them the global chip leader overnight, or even in a decade.

Analogously, the reason AMD is trailing Nvidia isn't just about hardware... There's many factors at play and this is true for TSMC as well
Being constantly on the edge of keto but not actually in ketosis means, for most people, low energy, headaches, and irritability.

Restricting carbs severely without the intention of entering ketosis is very not fun for most people, I find. It’s keto flu without any of the benefits.

I used to do that as a kid, but I had completely forgotten how to do that. It's been a long time since I saw a spinning top; I guess kids these days don't play with them anymore.

If I remember correctly, our tops were blank wood as bought and we tended to paint them in our designs.
> but under control

I could quit at any time, I just don't want to.
> After all, global warming is a feedback loop, almost 100% running on water vapor.

The positive feedback part kicks in with water vapor and methane after thresholds are crossed - for now the preamble heavy lifting to approach thresholds has been done by a century of what has now ramped up to an addition 11 billion tonnes per annum of additional C02 added by human activity that's over and above the 'normal' (for past 200K+ years) carbon cycle of volcanoes, fires, and organic growth and decay.

We're quite away from "almost 100% running on water vapor" to date.

“Thermal Equilibrium of the Atmosphere with a Given Distribution of Relative Humidity” Manabe, Wetherald (1967) https://journals.ametsoc.org/view/journals/atsc/24/3/1520-04...

By the time we get to a majority positive feedback loop it may well be too late to reverse .. that's one of the intriguing mysteries to complex non linear dynamics.
I came to say this, but also that would be creepy as hell!
(I assuming you mean "moment" when you say "momentum" - https://en.wikipedia.org/wiki/Moment_(physics) )

Once you've got water pouring in, all the stability angles start changing. Usually very fast. And returning "back to 0" would require both the storm suddenly calming, and floodwaters to be free to (in effect) move to the ship's centerline. (Some hull shape will do that, with limits - but I'm not a naval engineer, and don't have a useful real-world understanding of this.)

I think the critical thing here would a graph showing the ship's righting moment and the storm's heeling moment, both vs. angle of list, with the former shown both with and without the keel extended. Actually, a series of graphs - the wind wasn't constant, and the righting moments changed as the ship flooded. Those could answer the "would extending the keel have saved the ship?" fairly well.

Flip-side, extending the keel would have changed the ship's draft from 4m to 10m. The ship was dragging its anchor. I don't have a chart of the waters the ship was in, but running its deep keel into the bottom could also have ended badly. Has that consideration been mentioned?

EDIT: Here's the former captain's take on this, from the article:

> The Angle of Vanishing Stability is the angle of heel at which the vessel righting moment reaches zero, meaning that the vessel will not return to upright. Again, I forget the actual numbers for this, but the figures would be around 90 degrees with the moveable keel lowered and 75 degrees with it raised.

> The Downflooding Angle is much more important though in the scenario we are talking about. This is the angle of heel at which water will start to enter the vessel (usually through engine room or accommodation ventilation ducts)… once this starts the vessels is in serious trouble as stability is quickly reduced or lost due to the flooding.

> The downflooding angle for Bayesian was around 40-45 degrees… much less than the AVS. So, unless the vent dampers are closed (which with HVAC systems and generator running they would NOT be as they need to be open for that), the vessel will start to flood rapidly if heeled more than the downflooding angle.

My initial response to you was probably based on his strong emphasis on downflooding angle, vs. vanishing stability angle.
At least it is Mountain Dew and not Brawndo.

Mutation testing can be a ratchet. When new code is introduced, the numbers must still meet thresholds. That tells us resulting changes do not leave the codebase worse off than before.

Threshold numbers are stored alongside the code. For pitest (Java), those are test coverage, mutation coverage, and test strength.

Baseline is per-repo, so comparisons are always to the repo itself. Existing projects start at when thresholds are introduced. New projects start at a higher bar.
That is not as easy as it looks. My granparents had a number of tops like that (not German, but same style you threw it with a string)... none of the kids could get them to work, and (comically) none of the adults could get them to work either. Some child would find them during the holidays and some grandparent would say "oh yes I remember playing with those, you use a string" (goes and finds string, spends next 15 minutes proving they just can not do it). Then the kids would run off and spend an hour trying to get it to work, unsuccessfully.

I think when I see this video, we all were throwing it upside down.

How well does Flox work out of the box? I would really like to introduce Nix to the dev environments in my company but the struggle of maintaining nix files and flakes is too large. I've looked at DevBox and it looks quite accessible but Flox also looks like a nice way to sneak some of the Nix goodness into the company.
Really...? In my experience, whilst Erlang is slower than most AOT languages, its an order of magnitude faster than Python or Ruby. Most benchmarks I've seen also back that up.
I know about these tendencies, but I can't be sympathetic to them. (Re)gaining hearing is a physiological improvement; those with implants can even "turn off" noise. What these deaf people may lose is a specific deaf culture, held together by current necessity. But then the sides are flipped, and they are the ones perpetuating a non-inclusive (sub-)society.
How do poor people on food stamps (EBT) in this crazy made up "store" place pay for (approved) food goods? The card terminal that reads their card connects to their balance via the Internet. without that, they're not able to buy food.

How do goods get to the store for purchase? Does any of that need the Internet? Like when the merchant pays for goods using a credit card?

For better or worse the Internet is critical infrastructure for modern society these days, it's not just scrolling on TikTok.
I can't read the article for comparison, I think it got hugged to death.

I'll look later when the rush dies down to see how they compare.

[edit] I just realised it's been almost 10 years and I'm back to doing the same thing in a different domain. Right now I have a computer training an AutoEncoder to make the best 128 byte 32x32RGB images it can.
Less food.
We can't even do something simple that I would like to see happen — make WIC universal with no conditions. It already covers about half of all children so it basically only doubles the budget. We can afford it and it saves so much time and energy trying to police the system.

Another one is free of cost universal pre-K. A lot of women can't go to work because there is nobody at home to take care of their children. But really the easiest lowest hanging fruit is universal WIC. Make it available to everyone so it is easier for us to tell people to get it.

Blood sugar monitoring with CGM is extremly expensive and potentially flaky. When you use it to monitor your blood sugar for medical reasons you still need to do professional controls. Diabetes Type-1 is an autoimmune disease it kills beta cells in the pancreas. They are slowly or quickly killed in the span of weeks or sometimes a couple of years. AFAIK once it has started it is impossible to stop at the moment. With type-2 I have no knowledge of a way to do a diagnosis decades before you get it, considering how different diabetes is between people I am sure you can catch some people. I have a hard time believing that CGM data will be usefull without deep context.

I think the suppliers of these peripherals are way to good at sales pitch to be trusted.
One example - https://zoe.com/our-science

I don't think it's the engine exhaust, neither the engine air intake.

I think the exaust has possitive pressure when the engine is running which would prevent water from entering. OTOH water entering the engine air intake.. would be quite bad for the engine I guess, so there'd be protection against that. Also both of these (exhaust & intake) are not free to the inside of the vessel, but form a closed circuit with the engine, so there's no way to flood the vessel through those.

So probably we're talking about the engine room *ventilation* openings that would let water in.
> In diabetics, maybe.

Sushi rice causes me (type-1) to spike. Other kinds of rice (jasmine, pilaf, etc) behave more like normal carbohydrates.
No one is looking at Digimon and saying it looks like Pokemon now, but in the 90s they sure as heck were. People's mothers (ie the key demographic for "the uninitiated") commonly confused one for the other, even the TV show. This is no longer the case purely because Digimon is far less popular.

Bearing in mind pretty much all Pokemon designs follow the rule of "what if a mythical animal existed in our art style", it is in fact shockingly easy to accidentally ape a Pokemon design just by cartoonifying mythos.

This is incidentally also true of Pokemon, who were accused of ripping off Dragon Quest when the first games started coming out. Does anyone remember that at this point?

> Now I'm just waiting for the inevitable "AI image scaler" that handles text inside images.

I'm surprised this isn't a thing already, as it seems doable with what people called "AI" 20 years ago. I mean, unless some unusual/non-default font was used, upscaling text on an image should be almost trivial. Ligatures notwithstanding, "printed letters" have a fixed shape, so:

1. Identify the typeface, size, weight, etc. by looking at the pixels of the text;

2. OCR the text (which should be 100% reliable);

3. Blank out the original text pixels; re-render the content (from step 2.) at a larger size (using parameters from step 1.).

I'm hedging here; it feels to me that OCR-ing normal text that never left the digital realm should be 100% reliable, but I'm not a specialist in that subfield so I surely must be missing something...
The pricing isn't absurd, but I also think this one will stay on the shelf. Their Claude 3.0 lineup was so good:

Haiku as a very cheap and fast option for low complexity stuff. Sonnet for most people and their fairly advanced problems. Opus as a very expensive, slow but very capable model. Haiku 3 was 12x cheaper and Opus 5x more expensive than Sonnet. This made a lot of sense to me and I used every single for for different tasks.

With 3.5, that's a different story. They're clearly running into GPU limits and dropping Opus for now is a reasonable thing to do. Sonnet has improved so much and OpenAI is behind them anyway. But this move on Haiku is stupid on so many levels.

Their lineup is down to two models, which are closer than ever in performance and price. It's like "Sonnet" and "Almost Sonnet" and at a 3x price difference, I'll stick with the OG. For a lower cost model, I'm going to stick with GPT-4o-mini.

Also, people make connections to products through names and not benchmark results. It's great that Haiku has improved so much, but it's still Haiku. We know models get better, but increasing prices 4x for a new version of an existing one doesn't feel nice.
This was cool on 4chan 10 years ago. I remember writing my own implementation using lots of unsafe C#.
Let’s say, for sake of argument, that only 10% of crimes committed due to entrapment would have been committed without entrapment. Are you still okay with that outcome? At what percentage does entrapment become a good thing? 50%? We can use statistics and models to estimate this I think, it would just be a lot of work.
For me, I'm not overweight at all (quite the opposite, actually), but I'm totally addicted to sugar. To the point that food other than carbs/sugar is really uninteresting to me. Doesn't help that I don't like meat. What else can I eat? I can't survive on just vegetables
Retain taste? Fat doesn't taste sweet, at least not to me... the only reason I can imagine is they do it to mask a bad taste, or just to hide that the ingredients are bland (and/or low quality). That, I can understand - although still not approve as it's even worse, lying under the guise of sweetness.
It's absolutely worth the experiment of getting a continuous glucose monitor for a couple of weeks to see where your lifestyle is at.

I quite liked the Freestyle Libre 3, which you can buy online without a prescription. The software is rudimentary but it'll give you the information that you need. A single device will last for (up to) 2 weeks, which is better than the alternatives I looked at, hence my recommendation.

IIRC from Peter Attia's book Outlive, you are aiming to keep blood glucose at an average of 100, with very few spikes above X (I think he said 160, but would need to check). He does suggest once you have measured for a few days to push the envelope with carbs, sugars, etc and see how your body reacts.
But sushi rice is usually prepared with extra sugar, it's not plain rice.

It's not (just) cost saving. Having owned a yacht, everything breaks all the time. The environment is extremely harsh on everything. Seawater is corrosive. Even high quality stainless steel (expensive!) will corrode. Sealife is invasive. Every nook and cranny is under constant assault from all sorts of weird little critters.

The most robust solution is to keep things as simple as possible. Any bells and whistles you add will become liabilities very quickly, and if crucial systems depend on these bells and whistles, you can quickly get cascading failures.

I learned in about 2 months that you want the most crude, easy to repair and reliable solution to important parts and you want them cheap - because you'll be replacing them regularly. Expensive solutions will provide very little relief from this (if any at all). If the TVs in the guest rooms break regularly because of constant vibrations, that'll annoy the guests, but the ship will float and go forward. If your fancy fly by wire engine controls corrode and you are out at sea, it's mayday time. A lot of smaller boats still use mechanical wire actuation because it can be mended literally with a string.
This is an interesting thought. I have not thought about it like that before.

Like, what are the odds some local 'boomer NIMBYs' or whoever the scapegoat is succeed about everywhere.
Well, you say that as a rebuttal, but that's literally true. Alcohol is a known carcinogen, it causes cancer in humans without a shadow of a doubt and there is no disagreement on this matter. Medical professionals and government agencies worldwide agree on this fact. But we still drink alcohol, whether for the taste, to unwind, or for other reasons, because we accept that so long as it's not excessive, it's not too bad.
Speaking of that energy spike, is it something you would get from sweetened ham? Does it have that much sugar oh my... Isn't the spike rather coming from a piece of cake, which happens also to be the proper way to consume sugars? That or fruit, also good.

No, that was just the part where a lot of supposed "blue zones" (regions where average lifespan is significantly higher than average) happened to be islands in the Mediterranean. A lot of which was indeed due to pension fraud rather than above-average age, which is easier on those remote islands.

The Mediterranean diet is still backed up by dietary science, which has actively tried out various interventions and compared results. This paper apparently being one of them.
