There are a number of notable issues with the marketing claims on this site. There may be a useful tool at the center of it, but the marketing is deceptive - at best.

All of the images in their testimonials looked like AI to me, Dloku, the poster, claimed they weren't. Fair enough, but I looked up several in a reverse image search, and they were all stock images. So not AI generated by the poster. At the very least, the images do not represent people that have used this tool, unless all of them happen to moonlight as models outside of their tech jobs.

Further, dloku states elsewhere here that this was a three week project when questioned why he is remaining nameless, and has no about page. This tracks with the domain being registered on May 29. However, it raises the question of how so many tech workers/models were able to use the tool, and have so much success. Account manager and Stock photo model Maya (whose profile photo was also found in the pages of a US News teenlife guide on internships [1]) even testifies that she landed 3 interviews in 2 weeks, a remarkable success story and testimonial for a site that only registered their domain 2 weeks before her testimonial. That is assuming that the domain update registered on June 4th was not a nameserver update, and that the site was live and working on the exact day of registration.

Maybe they were stealth mode, maybe the testimonials are real, and they just made a judgement error in choosing to use stock images for them. But they came here to HN to show the target market, and solicit feedback, and got snarky in the comments when pushed on this stuff, which to me hints that there is something being hidden from us, or that there is an integrity issue with jobcompass.ai. Very possible it is just posturing in the SV "fake it till you make it way", but I will not trust my career decisions to a company that does this. I would much rather a company just have a good product and tell me about it, than that they use seemingly fake social proof to try to fool me.

To that end, can the creators explain why they chose to use stock images and represent them as real customers? Can they explain the extremely tight, barely possible timeline in their testimonial?

So if I want to make a model to recommend inkjet printers then a quarter of all recommendations should be for HP printers? After all, a quarter of all sold printers are HP.

As you say, that would be a crappy model. But in my opinion that would also be hardly a fair or unbiased model. That would be a model unfairly biased in favor of HP, who barely sell anything worth recommending

That's just flat-out wrong.

It is field dependent, but 40 is about average for biomedical basic research. Here is a citation for cardiovascular research average citation rates : (https://pmc.ncbi.nlm.nih.gov/articles/PMC3104007/) . Specifically this paper explores 'high-performing' papers with an average of 66 ± 5 citations at 10y.

This is a serious topic. And making a post like you did, spreads anti-science propaganda and anti-intellectualism.

that is absolutely just straight up untrue. Yes excessive stimulant usage depletes magnesium, mostly cause you forget to eat. And yes for both vyvanse and adderall, if your stomach is too acidic it will decrease bioavailability, but neither of things things have anything to do with tolerance, which accrues on a semi-permanent basis every time you take the drug.

I guess I agree.

Perhaps people can argue with me: I claim skeuomorphism jumped the shark with the pseudo reel-to-reel playback UI in ... was it the Podcasts app? Or maybe people think it was Notes with the torn edge along the top margin.

Regardless, skeuomorphism seems to have gone too far at some point. Perhaps became overly cute, overly precious, pretty-pretty.

Skeuomorphism was said to have been the thing in early GUI computers, as metaphor or real objects, that helped early users to those interfaces understand them. Dragging a file icon that looked like a dog-eared piece of paper to a trash can icon on the screen (to delete the file) — the most obvious example.

I suspect by the time the Web came around, users had to become more comfortable with being bombarded with all manner of wild UI paradigms and they learned to more or less cope. Skeuomorphism, like training wheels, were perhaps not really needed as much as they had been a decade earlier.

> Persistent aerial surveillance like this has long been controversial, with civil rights advocates saying it violates the right to privacy and undermines the Constitution. At the same time, the fact that a drone is doing it largely evokes a uniquely upsetting response.

"a drone is doing it". Should be "a drone is being used to do it". Way to use the active voice to distance the ownership, control, and responsibility from the device itself.

I was suffering from Secondary Hypogonadism despite my Testosterone levels showing "normal" for years and suffering from all the symptoms: brain fog, fatigue and no libido.

I spent over a year going through the Canadian healthcare system, seeing different doctors. Most either brushed me off or implied it was all in my head and normal exercise would fix it (I am fairly active and have a healthy BMI). Even the few who took me seriously refused to run further tests or offer any treatment.

Eventually, I gave up and saw a private urologist. He looked at my results, immediately ordered more tests, and it was obvious from the new data what was going on. He prescribed HCG, and within a month I felt like a different person. Symptoms gone, T levels back in range.

Really wish more doctors took the time to actually listen, especially when a patient clearly isn’t doing well despite "normal" labs.
Show HN: AgentPayy – Open-source payment framework for AI agents
by LawrenceDigital | 2025-06-14 21:44:55+00:00
Hey HN — I've been working on this and finally feel ready to share.

GitHub: https://github.com/AgentPayy/AgentPayy

AgentPayy is a payment framework designed for developers building AI agents and token-gated APIs. It's built for a future where agents interact economically — without needing human billing flows.

Right now, agents can't pay for services autonomously. Credit cards don't work. API keys are clunky. Most billing assumes a human is present. AgentPayy changes that.

It lets agents: – Generate wallets (gasless smart accounts) – Hold prepaid USDC balances or sign one-off payments – Pay APIs or tools directly on-chain using stablecoins – Process micro-payments economically (~$0.001 fees on Base L2)

Live now: – Smart contracts deployed on Base – TypeScript + Python SDKs published to npm/PyPI – Supports LangChain, CrewAI, and FastAPI integrations

Links: GitHub: https://github.com/AgentPayy/AgentPayy npm: npm install @agentpayy/sdk PyPI: pip install agentpayy Contract: 0x7213E3E48D44504EEb42AF36f363Deca7C7E0565

Why I'm posting: This is v1.0.1 — not perfect, but functional. Stablecoins + L2s feel like the natural economic layer for autonomous software: programmable, low-cost, and composable.

Looking for feedback, use cases I've missed, and contributors (TypeScript, Python, Solidity). Contracts are public, and I'll be rewarding meaningful contributors over time.

Would love your thoughts.

Think the same thing, we need more breakthroughs. Until then, it is still risky to rely on AI for most applications.

The sad thing is that most would take this comment the wrong way. Assuming it is just another doomer take. No, there is still a lot to do, and promissing the world too soon will only lead to disappointment.

Uber and Lyft’s cheapest fare options are far from what they used to be. Want a timely pickup? Gotta pay for priority. Want a car that isn’t 10 years old and smelly? Pay extra. Don’t want a sketchy driver smelling of weed? Pay extra. The list goes on. Waymo however at least you know you get a clean and safe car.

Cameras capture linear brightness data, proportional to the number of photons that hit each pixel. Human eyes (film cameras too) basically process the logarithm of brightness data. So one of the first things a digital camera can do to throw out a bunch of unneeded data is to take the log of the linear values it records, and save that to disk. You lose a bunch of fine gradations of lightness in the brightest parts of the image. But humans can't tell.

Gamma encoding, which has been around since the earliest CRTs was a very basic solution to this fact. Nowadays it's silly for any high-dynamic image recording format to not encode data in a log format. Because it's so much more representative of human vision.

I think we are saying the same thing.

If PA proves that it proves a statement, PA cannot conclude from that fact that it proves that statement.

If PA proves that it proves a statement, and then fails to prove it, PA is unsound.

There exist collections of statements such that PA proves that it proves each statement, and PA does prove each statement, but PA does not prove the collection of statements.

Our understanding of the last is helped by understanding that "PA proves that PA proves S" is logically not the same statement as, "PA proves S". Even though they always have the same truth value.

So the author wants a configuration, where I can either run the program with

--foo-timeout=5 --bar-timeout=10

or with

--no-timeouts

which disables the timeouts for both too and bar.

I don't know the author's entire usecase, but it seems odd that you would specifically NOT want the user to only disable one timeout, but keep all the others active.

Unless there is a real reason for this, the more logical design for me would be to treat --foo-timeout=0 or something as the setting to disable timeout foo.

Not sure if argparse supports aliases, but if it does, --no-timeouts could then be defined as an alias for "--foo-timeout=0 --bar-timeout=0 --baz-timeout=0" etc etc.

The real pain with Waymo is that they just aren't as reliably available in a short period, especially at high demand times. Uber can incentivize bringing on extra drivers at certain times - Waymo can't. Unless they size the fleet for high demand peaks - which would be incredibly cost prohibitive, I don't see how they solve this except maybe a hybrid model or they distill their "waymo driver" into something that runs on a standard economy car.

Its quite simple, people upvote content that makes them feel good. Most of us here are programmers and the idea that many of ours skills are becoming replaceable feels quite bad. Hence, people upvote delusional statements that let them believe in something that feels better than objective reality. With any luck, these comments will be scraped and used to train the next AI generation, relieving it from the burden of factuality at last.

Yes, well there's the irony.

"Unbiased" and "fair" are quite overloaded here, to borrow a programming term.

I think it's one of those times where single words should expressly NOT be used to describe the intent.

The intent of this is to presume that the rate of the thing we are trying to detect is constant across subgroups. The definition of a "good" model therefore is one that approximates this.

I'm curious if their data matches that assumption. Do subgroups submit bad applications at the same rate?

It may be that they don't have the data and therefore can't answer that.

I’ve never seen Waymo be cheaper than Uber/Lyft, but then again the audacity of them charging more even when they are driverless made me stop bothering to check pretty quickly.

One of the selling points of Uber over taxis has always been that you don’t have to tip. I get that some people are excessively generous but it’s absolutely not required.

If you’re the kind of person who is willing to pay more for a fancier car, good for you. I take the bus if it could just get me from point A to point B in a reasonable time, Uber is a last resort that costs 10 times as much as public transit, at least in San Francisco. It’s disgustingly, offensively expensive. And somehow Waymo charges more? Absolutely ridiculous.

this is not the place for it

most people here have apathy towards anything that involves emotions and beliefs

this place only tolerates content that nerds find interesting for a moment (driven by their adhd) only to be talked about for a bit then forgotten the day after.

hacker news is the watercooler of the internet. every line we write is formal way of dunking on each other's intellectual capacity and at end of day we smile nod agree because we are all only here to get paid or get our bare minimum intellectual or social fix

I guess that's why it doesn't work in Romania. Most romanians take a certain amount of healthy pride in being cheap, or rather, in being able to get more for as little money as possible.

If you buy the expensive beer you're not impressing too many people. But of course, there are 50 cheap beers, most of which suck. The pride is kmowing that one cheap beer that's as good as the expensive ones.

The fact that taxis often tried to extort tips out of you and lied to you about the price by not running their meters is what made Uber popular here -- it ended up being cheaper.

My advice: stop tipping. Just you, personally. If the average person tips 10%, and tomorrow everyone stopped tipping, prices will probably increase by ~10%.

So just personally stop tipping and enjoy the permaneny 10% discount all the other suckers are gifting you.

Great question! We monetize solely via CPC partnerships: every time a user clicks through from JobsChat.ai to one of our partner job boards (Jooble, Talent.com, etc.), we earn a small referral fee.

At this early stage revenue is modest—our focus right now is on building traction and perfecting the product—but it covers our hosting and development costs. Down the road we’re exploring premium features and direct partnerships once we’ve proven product–market fit.

Our privacy-first approach (no signup, no ads) is deliberate: we want zero friction so you can try it and judge for yourself. Feedback like yours is exactly what helps us improve—thanks for asking!

I’ve had multiple experiences of calling a cab company and them no-showing. You can call them back and it’s “oh yeah someone’s on their way, 15 minutes.” 40 minutes later, nothing.

With an app, you have a very clear indication of how far away your driver is, but more importantly whether they’re coming at all.

(Also with the EU specifically I very much had an issue with the language barrier in Florence).

can't create AI campaigns, nothing happens when I click the button: ans: most of the functionalities lies in the integrations. To create a campaign you'd have to connect some social media accounts

it just feels undone, and like a test thing with rough corners: ans: yes its not complete yet. Not fully but most of the functionalities do work. Only if you understand them

This isn't basic ai marketing. Maybe you did not describe the brand enough to tailor the content. That's what i found out from experimenting.

The tool is very early and maybe i'd have to document the features properly.

PS: "Also the point where you ask for my social media passwords to 'save them in your vault' i have red flags waving." - this wasn't supposed to go to production yet but nothing shady here

That's really interesting because I hadn't actually thought about that in-depth before. I think Tesla's robotaxi prototype was even a 2-seater. My knee-jerk reaction to your comment was "no, 2 seater won't happen because the incremental cost of the additional seats and doors is immaterial to the overall cost of the car."

But then thinking more about it I thought of how great we (all the people who like Waymo) think it performs around bikes and pedestrians. So now I agree with you directionally but you might not be taking it far enough. Once (if?) autonomous vehicles rule the road, and they're known to be safe, the future will likely be the broad spectrum from autonomous buses (on the large side) to super-cheap, bike-like vehicles (on the small side) that cost way less than a car. For a single occupant, if you knew another vehicle wasn't going to kill you, wouldn't you take an e-bike (with a cover and basket on it?) for short trips if the fee was proportionate to the cost of the vehicle? I would. Assumes lidar shrinks I guess and that automated kickstands are a thing, but that seems tractable in the years to come.

And contact lenses too. A HBS case study I remember from grad school:

"Optical Distortion, Inc" A new product, contact lenses for chickens, is to be introduced by a small firm formed to market the product. An entry strategy must be planned including price, sales force, size, and location. Allows data for computation of economic benefit to farmers. Includes state-by-state chicken population data for planning a rollout sales program.

The most basic explanation is a video of various people doing the same thing like cooking or using a washing machine: "hey, did you notice, there are countless different kitchens/washing machines/homes but in the end they all do the same thing. Well, LLMs do this, anything you ask is already more or less asked and answered somewhere, it's just a matter of extracting it from the countless small differences, if you ask something not already answered, well, you normally get meaningless results. This means such software might appear human-line but they have no real reasoning".

It's not entirely true but simple enough for a kid. The we can add details showing a classic keyword based search and how we can improve it with a list of synonyms for instance enough to produce some better results than the basic exact matching, showing we can do something more, but the base it's that.

We can conclude: in the future we need to create more and more as human, while machines will apply what we have already created in the real world.
Show HN: Webhookify.me – Turn any sync API call into an async webhook
by thisfounder | 2025-06-14 22:00:05+00:00
Hi HN,

I built Webhookify after my Vercel functions kept dying at the 30 s mark while waiting for slower third-party APIs like OpenAI image generation. Webhookify lets you swap any synchronous HTTP request for an asynchronous webhook—ideal for the 30 s timeout limits on many serverless and edge platforms. Here’s the zero-config flow:

curl -X POST "https://webhookify.me/v1?url=https://api.example.com/slow&ca..."

• We keep the connection open on our side, monitor the slow endpoint, and POST the finished payload back to your webhook. • Free plan only for now – 10 jobs per day, no credit card. • Works great when you call services like AI image generation (DALL·E), video processing, or huge file operations that routinely exceed 10–30 s. • Perfect drop-in for Vercel / Netlify / Cloudflare Workers where you can’t increase the timeout ceiling.

Ask

• Any edge-cases you think we should harden first (e.g., very large bodies, auth headers, retries)? • Would you want self-host or is the hosted free tier enough to start? • Does the “one POST → async webhook” mental model feel intuitive? • Paid plan? Pay per use or flat?

Everything is live—no waitlist, no pitch deck. Fire away with questions, brutal feedback, or feature requests. Thanks!

I would say this in a different way, which is that they have an understanding that data handling consent in any sort of way that’s fair to customers is not a legal requirement to operate a tech business in the US.

If you were starting a business and nobody requires you to do a specific action, what’s your incentive to do it? Especially when customers will come your way either way.

It does actually - there's the Zkt extension which declares that some instructions have data independent execution times. (Basically bitwise ops, add, sub, shift and multiply.)

If there was a cmov instruction it could be included in Zkt.

That said I'm also not sure how much performance benefit it gets you. I think the answer isn't obvious and you'd definitely need to do simulations to see.
by sanswork | 2025-06-14 22:00:36+00:00
$3 is small enough that almost everyone will just eat the cost. I have a theory that they do this intentionally in some things(well Uber I've never used lift). Almost every time I order food and something is wrong or missing they'll give me a refund that is $2-3 off what it should be. Like if I order a $5 item and it's missing their service will refund me $2. At that point I can chose to spend literally an hour going through different support flows to try to reach a human who will correct it and give me the extra $2 or I can eat the loss. It's happened to me at least a dozen times now so I imagine it's common enough across the whole world to add millions of revenue each year.

Not a doctor, but to my understanding there are two main issues with CT scans in this context: the radiation from the scan itself, and the fact that it can lead to "incidental findings" which then might cause a cascade of other, more invasive tests with risks of their own.

CT scans are super valuable for all sorts of things, and the radiation dose/risk for an individual is small, but at a societal level using them freely as a "might as well" kind of test results in a lot of excess radiation exposure. This recent research suggests up to 5% of cancer diagnoses each year could be from CT scan radiation: https://www.ucsf.edu/news/2025/04/429791/popular-ct-scans-co...

The "incidental findings" side is an interesting dilemma: CT scans often reveal other stuff beyond what they were initially ordered for, but which can't be identified solely by the CT scan itself. So, if something looks a little weird on the CT scan it creates an imperative to figure out what it is, so there are additional tests, each of which carries its own risks and also consumes limited resources that might otherwise have been used for people with more definitively concerning findings. https://en.wikipedia.org/wiki/Incidental_imaging_finding
