I’m a small business owner — I run a car tinting business — and I built Revumatic because of years of frustration with Yelp, Groupon, and Google Ads. These platforms were supposed to help SMBs grow, but in reality: • Yelp filters positive reviews unless you advertise • Groupon sends bargain hunters and takes huge cuts • Google Ads costs keep rising, with no guarantee of leads

I realized SMBs shouldn’t depend on platforms — we grow through trust, quality of service, and referrals. So I built Revumatic: a B2B2C, AI-powered growth loop that starts at the point of service.

Customers scan a QR/NFC stand, leave an AI-assisted review, and get a referral link. Rewards flow to both sides and enter a local Trust Marketplace, giving exposure to other verified SMBs — without ad spend or platform fees. On the business side, AI helps respond to reviews, nurture leads, qualify prospects, and convert them. The result is a self-reinforcing loop: customer → review → referral → reward → new customer → repeat.

Technically, I built this with Node/React, event-driven workflows, LLMs for guidance and follow-up, and a custom referral/reward engine. I’m a non-technical founder, learning as I go, and I’d love HN feedback on the Trust Marketplace, ethical AI use for review guidance, and any loop or scaling pitfalls.

I built this because I needed it myself — SMBs deserve tools that let them grow based on their own service and trust, not ads or intermediaries.

Looking at Table 2 and as the name suggests, COVID is included in "all-cause" mortality. Your statement does not follow because it could have made COVID outcomes better yet "all-other" causes worse for a neutral "no increase in all-cause". If you look at Table 2, you can see that the vaccinated group is less mortality in all diseases. That being said, as much as I think this is over-stated, this is very much a correlation thing because we all know that unvaccinated individuals live their lives differently compared to vaccinated individuals. Even accounting for similar statistics, the one group is prone to higher death rates not because they are unvaccinated but because of the reason they are unvaccinated.

There's often a certain kind of (and if this is you well, fight me I guess lol) rationalist commenter online who will say something like "Why do you want to regulate misinformation, do you think you're better than Fox News viewers? Like you're this smart elitist on a hill who's not vulnerable to misinformation? Why should you get to decide what other people consume?" That's meant to sort of feed into I think a normal "good" persons humility, and while I don't have a great response to the accusation, I'm confident it feeds into some massive rhetorical fallacy.

I do observe that there are some folks who seem more vulnerable to misinformation than myself, and I do think it's a debate worth having.

> That's not what I've seen.

It's common enough that there are state legislatures trying to ban mRNA vaccines all together. [1]

> since covid risk to young children is negligible, why the heck are you requiring them to get a shot?

Kids spread covid and no vaccine is 100% effective.

I've not seen any evidence that the vaccine is dangerous to any age group. There is plenty of evidence that COVID is deadly to the very young, the very old, and a bunch of other people (including those with compromised immune systems).

It's exactly the same reason kids should get the flu shot.

That said, there's no requirement anywhere for kids to get either.

Why is this a negative for consumers? Doesn't everyone complain how they have to subscribe to 5 different streaming services, and plenty of people have to pay for a service just to enjoy one or two series?

I don't think consolidation is necessarily bad. It makes sense from a cost perspective too. I guess they could just license out the content, but this will probably grow the catalog a lot.

> Are cinemas now second behind streaming?

It feels like a race to the bottom. Movie and TV content quality has taken a nose dive in the past decade.

Yes, there are exceptions, but it’s hard to find these days.

Maybe it’s because producing movies/TV is so much easier and cheaper that there is now so much low quality noise, that it makes finding the high quality signal so difficult.

But it seems like you used to be able to go to the theater and you’d have to decide between several great options.

Now, I almost never care to go because it’s only about 2-3 times a year that anything comes out worth seeing.

I was playing around with context engineering ideas and I built a framework that seems to work well. Not claiming any true rigor, but this has built some really complex tooling for me if used properly in your favorite agentic ide. Might be more of an explorative tool for formal math, but for code that can be unit tested, this has give me great results.

Rising sea is the future imo.

Thanks for your comment. It looks to me that most of the people who work in engineering area express some form of understanding or give the benefit of the doubt to the situation while people from outside the field borderline call for malice in the side of BMW.

I think both are right. Engineering a modern car is really complex as you pointed out but the customer also has the right to say, "well that is what you are paid for". In the end the customer can just go to the next car brand.

I own a relatively recent BMW but it is only a mild hybrid diesel (4 year old M340D) and before I even received the car, they changed the whole engine and did not release the car until that was executed. That was done by the dealer, and i never knew what was the reason.

On the flip side of modern car engineering I once had a check engine light called the dealer and with authorization prompts on my side they were able to tell me some gas exhaust sensor was malfunctioning and I would be able to go there at my leisure, as it was not urgent. That was nice. When i bought the car I had 5 years of maintenance included and this is one of the nicest things about owning a car in modern times. They even call me when it is about time to do the maintenance asking for when I am available. I never owned top brand cars before but this is for me worth the premium so far as it is one less thing to organize.

Apart from the normal maintenance and the above I never had any issue with the car, and it is a very big difference between a 2001 Passat TDI(my youth car) or a Ford Torneo Connect(the car i am aiming to exchange for due to family reasons).

The PinePhone has 6 dip switches for this 1. modem, 2 Wifi/BT, 3. Mic 4, rear cam, 5. front cam, 6. headphone / serial port. They say it will stay in production for 2 more years, but a lot of the accessories (LoRa cover, keyboard, etc) are already gone.

If nothing else it is a fun platform to hack on. I'm currently hacking a toy OS for it, and the documentation for the SoC is fairly complete. I'd love an updated phone like this Jolly orange Jolla to hack on, but not at that price, and seems like it might be locked down.

This is why I incessantly preach to my coworkers: "you are not your job". Do not attach to it emotionally, it's not your child, it's a contraption to solve a puzzle. It should be easy and relieving to scrap it in favor of a better contraption, or of not having to solve the problem at all.

My good friend is a network engineer and provider in NYC for decades now, pretty good one at that. Has anyone deployed UniFi in a computer centric professional environment? Just to be more specific a bit, computer centric professional environment means networks and computers are the primary way of getting job done. He hasn't seen any UniFi but his home is all UniFi.

Saying blue collar work is "low-skilled" is probably inaccurate, I think the important distinction is that most blue collar work requires the person sitting at some physical location doing stuff, while significant amount of white collar jobs have a lower physical presence required.

Like if you work at an assembly line making widgets, the upper bound of productive work you do is proportional to the time you're physically there, so in this aspect it makes more sense for the employer to use that as a metric. In contrast a lot of tech jobs can be done remotely, sometimes if you're trying to solve a particularly nasty problem you don't even need an internet connection while you're thinking deeply about it.

You know Google pays Apple ~$20 billion a year to be the default search engine, right? The rumored deal with Google is $1 billion, so Apple is still up $19 billion.

There's only three frontier model makers: OpenAI, Anthropic and Google. So everyone that's using a frontier model behind the scenes is using one of these three.

It's likely whatever happens, it'll be running on Apple's Private Compute Cloud [1]—it won't be mined for ads, etc.

What you don't understand is on-device AI isn't going away due to using Gemini for Siri; they're two separate products. Using Gemini is the fastest way to add "world knowledge" to Siri.

Something doesn't happen until it happens. And even when it happens, it might fail.

So far China hasn't broken down many walls, for example I'm fairly sure they can't do what TSMC does.

And for media... guess what, they need to open a lot of things up. There's a lot more freedom of speech in the US, so US media can be about a lot of things interesting to the rest of the world. The US even has a lot media catering to other countries (for example media targetting Chinese audiences).

I mean, China could try that, we have the examples of Japanese and South Korean media, but both of those are democratic, and even then, it took them a long time to develop. Plus neither of them are near the levels of influence US media has.

Hi Peter, thanks for doing the AMA! I have a Delaware registered LLC (10 years old), I managed to get even an EIN remotely. However, I can't open a bank account remotely and so I have just been paying the registered agent fees and Delaware gov taxes for the LLC all these years. I however, genuinely want to come to the states to open the bank account and actually expand my business into the US. The LLC hasn't really had any annual meetings/etc. but taxes are always paid on time. How do I use my LLC to apply for a B1/B2 to visit the US?

OR should I just close it and try the normal route? Thanks in advance!

I have a theory about EVs - they don't allow much engineering range.

To have a broadly usable car, you need at least 50+ kWh battery, 100kWish fast charge, and basically almost everything you need in a big car. If you don't have it your car is not really usable as the main car.

Motors are small and efficient so they are not big cost drivers.

Small cars, such as 'cheap' B-segment cars still need all this stuff. If you look at the weight of something like a Renault 5, you find its not lighter than a Model 3. The manufacturer still pays for all that stuff, but the car's supposed to be cheap so they cant pass on the cost.

But in a small car, you have packaging problems with having to fit the battery pack, meaning you need to build them taller and draggier - that means your highway range decreases, and the big weight means big (and compact) crash structures, which again are more expensive.

In contrast, in a Model 3, you can make the pack thinner, design a more aerodynamic shape, have the big roomy frunk as a crash structure.

Your extra cost ist like tens of centimeters of steel and glass, but customers will happily pay more because its an upmarket car.

You can't really go beyond that, because the acceleration and torque is crazy even at the base level and at high speeds your range will still suck.

This basically means imo that the Model 3 and Y are at the ideal intersection of what the technology's good and bad at, and market positioning.

That's why I don't think Tesla will make a C-segment car.

People who believe in baseless conspiracy theories have to convince themselves that people who don't are operating in the same epistemic mode, picking and choosing what to believe in order to reinforce their prior beliefs, because the alternative is admitting that those people are operating in a superior epistemic mode where they base their beliefs on most or all of the available evidence (including, in this case, the fact that the """vaxxed""" people they know are all still upright and apparently unharmed after years of predictions to the contrary).

Your comment is a manifestation of this defense mechanism. As real evidence piles up that you've been wrong, you retreat into these bizarre imaginary scenarios in which you've been right the whole time, and by projecting that scenario onto others you imagine yourself vindicated. But the rest of us just think you're nuts.

In 2013 they released the Jolla 1, a phone with custom hardware and Linux software. In 2015 they tried again with a tablet, but it failed on the side of hardware production and the company became insolvent.

In 2017 there came investors, among others ROS Telecom, a Russion telecom provider. They pivoted to only providing software, mainly on Sony phones. That is still ongoing.

Since the Russia - Ukraine war the Russion investors went MIA. The Finnish people from Jolla started a new company and had all assets moved to that company. They are now trying to rebuild the company and apparently extend into hardware again, even though the PCB design is off the shelf.

I have been a user since 2014 and am quite happy with their offering. It offers ssh root access if you want. Optionally manually installing software. Very much a GNU/Linux experience. Privacy focused and user oriented. And now slowly but surely there are parts of the software being opensourced.

Surely in these situations, the fact-checked information is more knowable than God. The fact checker can provide other sources that may support their position. The woman with a hotline to God cannot possibly provide any proof of her claims.

Comparing a belief in spiritualism to a fact checker thinking they've found misinformation is apples and oranges in terms of falsifiability.

>To be clear, I am not taking some specific position, but I think all these topics inform answers to your question. I think it's something with trade-offs that people have a tendency to over-simplify based on a limited view.

That's fair, I wasn't dimsissing the practice but rather just commenting that it's a shame the author didn't clarify their preference.

I don't think the popularity angle is a good proxy for usefulness/correction of the practice. Many factors can influence popularity.

Performance is a very fair point, I don't know enough to understand the details but I could see it being a strong argument. It is counter intuitive to move forward with calculations known to be useless, but maybe the cost of checking all calculations for validity is larger than the savings of skipping early the invalid ones.

There is a catch though. Numpy and R are very oriented to calculation pipelines, which is a very different usecase to general programming, where the side effects of undetected 'corrupt' values can be more serious.

By the grace of first past the post, winner takes all. This ancient system prevents people from picking shades of grey parties, since they simply don't exist in any significance. And from the other end it doesn't allow parties to split, since it will mean than the smaller block is immediately equal to zero (zero votes, zero seats). In when parties aren't allowed to split, they trend towards reactionism and radicalism, when radicals can hold the whole party "hostage". Applies to both sides btw.

Human gut bacteria have the Shikimate pathways so it can kill them.

Basicaly glyphosate could act like a gut bacteria antibiotic.

>> 54% of the human core gut bacterial species are potentially sensitive to glyphosate, which targets an enzyme in the shikimate pathway, suggesting that roughly half of gut bacteria possess this pathway

The soap is a surfactant to make the vinegar stick to the weed leaves for longer.

It's not necessary, but it probably lets you use a little less vinegar, so it's probably worthwhile. I don't add soap, I just spray straight 30% (agricultural) vinegar in the small set of areas where a torch would be dangerous.

Dried vinegar does not irritate dogs. They will avoid the area while it smells like pickles.

A better chemist than I will hopefully corroborate this, but I think that the strength of smell is directly correlated to the reactivity of the acid. So when the smell is mild (i.e. near the level of household vinegar (5%)), the risk to skin and mucous membranes is low-to-zero.

This was a very foolish choice on Netflix's part. Most if the iconic IP from WB/HBO has gone down hill in a dramatic fashion over the last decade.

Game of Thrones was good for a few seasons, but half way through the fans started dropping almost as quickly as main characters. DC movies have had very few genuine successes, even if they've technically turned a profit.

Putting all that content up on Netflix would be unlikely to pull in that many more subscriptions, and would require dropping the existing streaming service(s) and agreements to allow for exclusivity.

This doesn't bring significant talent or IP to Netflix, it's just an attempt to grab market share. I doubt they'll try to move anything out of WB/HBO's existing streaming platforms or agreements. This just looks like an attempt to increase profits by simply buying a profitable company and letting them mostly continue to function with minimal changes.

In other word, this probably isn't the worst acquisition possible for consumers, but it certainly won't improve life for anyone to let it happen, and it does consolidate market share and control when it comes to media. This probably won't be hugely evil, but it won't be good either.

If there's a legit, measurable performance or data integrity problem, start with that. If most of your production bugs come from a specific module or service, document it.

If it is only technical debt that is hard to understand or maintain, but otherwise works, you're going to have a tougher time of building a case unless you build a second, better version and show the differences. But you could collect other opinions and present that.

Ultimately you have to convince them to spend the time (aka money) on it and do it without making things worse and that is easiest to do with metrics instead of opinions

I'm pretty much always disappointed these days reading online discussions, and I sometimes think about how intentionally devolving most online conversations into petty slapfights is one of the very effective astroturfing techniques. It's basically signal jamming anything substantive or cooperative because people get tired sifting through all the noise and get mad reading all the bad takes. Though I have no doubt that many of them are still 100% genuine foolish humans.

No, you're right. SailfishOS inherits the core of the OS from the old Maemo of Nokia N900 fame (though the UI was built from scratch I believe). I tried it back in the day on my Nexus 4 and it was buttery smooth, even with all its fancy animations and gesture-based navigation, which was way ahead of Android at the time.

I always thought SailfishOS would really take off by now, given how advanced and polished it already was at the time, but Jolla's mismanagement nearly jeopardised the whole thing (they filed for bankruptcy last year).

Who makes the laws?

The rich and powerful through lobbying and direct corruption. Here’s a link just from today: https://www.somo.nl/the-secretive-cabal-of-us-polluters-that...

So any “rules based order” simply locks in the rules of whomever has the most money to bribe politicians

There are no corruption free entities because they are starting with corrupt roots and grow through nepotism and political favors

The proof of this is dripping out of every seam of human organization

Discouraging higher education, IMO, isn't a bad thing. Academia is too much of a walled garden that is too easy to enter.

This resulted in higher ed becoming a defacto requirement for many professions that could have been open to professionally trained or experienced people. Employers need to draw their baseline requirements somewhere and if expensive credentials are too ubiquitous, it's understandable they rather select from those who achieved them than from those who didn't (or couldn't afford to).

And it's frankly disgusting how many doors remain closed to yourself unless you got access to an .edu email. More people with academic interests not having acquired one might open the door to many more who discovered their academic interests later in life but can no longer find a way to enter that garden.

Isn’t that what most squatters are doing when they purchase something like “zero.ai” or “spectra.ai”? Even if the trademark doesn’t exist yet, they have no intent to use the domain for a business and are assuming someone will want to create a business or trademark with that name one day.

The problem doesn't appear immediately; it appears over time where the market has been consolidated into only a couple companies and then they can raise prices as much as they want because there is no alternative. This is what cable was like for a long time. Part of subscription fatigue is the constantly raising prices of these services that used to be very cheap. Netflix having WB content isn't a bad thing, the problem is ownership because it will not be available elsewhere.
