Show HN: I built Payments app to simpfy online shopping
Hey HN

Iam building a payments app that will change the commerce industry. Called KuwarPay, our bold attempt to simplify transactions and ability to shop directly from your social media.

About KuwarPay

KuwarPay is a user-friendly payment solution designed for individuals and small and medium businesses. I made a first product, how it's gonna work:

1. A customer finds your post and clicks on the link.

2. They're redirected to a checkout page, where they fill in their details and click 'Buy Now'.

3. Next, they're redirected to PhonePe to complete the payment using their preferred method

4. After payment, the customer is redirected to a feedback page.

5. Once payment is confirmed, you receive an order confirmation email with all order details, enabling you to fulfill the order.

Taking it to the Next Level

Iam exploring innovative features to enhance customer experience. Our next goal: enabling customers to shop directly from social media shopable posts!

Imagine:

- Shopping seamlessly from Instagram, Facebook and Twitter posts
- Exclusive discounts and offers
- Simplified checkout with KuwarPay

But I want YOUR unfiltered feedback. Tell me:

1. What Iam doing right?

2. What Iam doing wrong?

3. How to make KuwarPay unstoppable?

Share your thoughts or any advice on this, would be helpful for me

Thank you

I remember reading something about Tabata/HIIT being something you don't want to do every day, due to the high intensity and strain on your CNS. Is this not the thinking anymore?
Well good luck parsing sqlite syntax! I had to write a (fairly small) subset sqlite parser for work a couple of years ago. I really like sqlite, it's always a source of inspiration.

The railroad diagrams are tremendously useful:

https://www.sqlite.org/syntaxdiagrams.html

I don't think the lemon parser generator gets enough credit:

https://sqlite.org/src/doc/trunk/doc/lemon.html

With respect of the choice of the language, any language with Algebraic Data Types would work great. Even Typescript would be great for this.

FWIW I wrote a small introduction to writing parsers by hand in Rust a while ago:

https://www.nhatcher.com/post/a-rustic-invitation-to-parsing...
And yet if some other country bans US-controlled social media exactly for the same reasons, this works as a data point to label them as "lacking freedom of speech", "axis of evil", "undemocratic", etc.

But I do appreciate the honesty of at least admitting the hypocrisy.
The race condition bugs are typically hidden by different software layers. For instance, we found one that involves OpenBLAS's pthreads-based thread pool management and maybe its scipy bindings:

- https://github.com/scipy/scipy/issues/21479

it might be the same as this one that further involves OpenMP code generated by Cython:

- https://github.com/scikit-learn/scikit-learn/issues/30151

We haven't managed to write minimal reproducers for either of those but as you can observe, those race conditions can only be triggered when composing many independently developed components.
Author misses the point of self-hosted GitLab and conflates for some bizarre reason "self-hosted" as "free"... no, you still have to pay for it but it's not beloved VC "saas" model.

And in Europe topic of data governance is very much a thing...

I'm not sure why I'm being quietly downvoted. Here are some links showing the corresponding slippery slope: https://news.ycombinator.com/item?id=34098132, https://news.ycombinator.com/item?id=38256810, https://news.ycombinator.com/item?id=32304735, https://news.ycombinator.com/item?id=22610829
Why do we still have dumb password requirements? Why do we have SMS based 2FA? Why aren't we all using passkeys?

Security changes take forever. Old school sys admin and IT security types don't really like to keep up with web changes. And users don't know any better. And grandma is probably less likely to mess up a security question than figure out what to do when she upgrades her phone and loses all her 2FA.
I would strongly advise against broadly recommending this across the board, because while rinsing your sinuses can help with some infections, it can make the situation considerably worse if you're working with e.g. inflammation instead. For a lot of people the difference isn't easy to tell and they end up making their own situation worse. As always, ask a medical professional, even your pharmacist can tell you what to do or not to do once you describe the symptoms.
What's funny is that I didn't even read the article, it's prima facie parental neglect.
I also think this is a lazy claim. We have so so many internal sources of information like the feeling of temperature or vestibular system reacting to anything from an inclination change to effective power output of heart in real time every second of the day.
You're on the right track in channeling this negative energy into productive work on the company.

There are a few things to keep in mind, some of them you've already argued yourself. One, Engage is a common word, so that's on you, and two, more importantly, in today's SEO/ASO/other algorithmic wars, if you truly are the leader in this space, people will copy as much of your name/branding as possible to steal your customers' attention.

You are absolutely not in a unique position in this regard, if you want evidence, look at this top 50 generative AI mobile apps ranking: https://isarta.com/news/wp-content/uploads/2024/05/image-6-1.... Count the amount of Chat + "something" names, and the amount of practically identical logos as ChatGPT in addition. That's the game these days, if you are successful, you will be copied relentlessly.

And the copycats might not even be copycats in the sense you're thinking. Automated customer engagement, LinkedIn or otherwise, is probably among the top 3 ideas that came to mind to anyone working in the sales/CRM space as soon as LLMs became convincingly human in conversation. So it's just thousands of people realizing the same opportunity at roughly the same time, going out to build it, maybe checking if there's a significant player in the space already, learning from their mistakes, copying the parts that made sense, and firing on all cylinders to become the leader in the space.

Yes, someone with more money might even beat you to the #1 spot, and the people who you think are your competitors right now might not even be relevant in a year, when various CRM companies build this functionality into their systems as a feature. In an even worse scenario, companies like Persana might be acquired with way worse numbers than you have, because of the network, the budget, the lower risk due to being ex-LinkedIn, etc.

None of this is particularly "fair" in the school playground sense of the word, but rarely anything is in business. If you have a true competitive advantage in terms of product, you have better odds than most, but maybe someone is going to beat you on distribution, pricing, marketing, targeting, to the point that product will barely matter.

It's on you to figure out what you want to focus on, and what outcome you will be happy with. If you have the metrics, you can probably fundraise easily. You might not want to, because you want to bootstrap, but then stop wasting energy on thinking about competitors who are doing it differently. Whatever choices you make, make them, and focus on your own path.
Sounds like you might be looking for a Static Site Generator. Astro was already mentioned. There's plenty of others, mostly geared towards blogs. I also had success with docfx and MkDocs, both for project documentation.
This kind of advice generally rests on it being useful to the majority. And I certainly have seen leaders who trusted their guts while making absolute dumb, idiotic and really avoidable mistakes on the way.

If you are a 2,5m of height and your basketball advice is to "just lift your arms and let the ball fall in", you are not wrong, but your advice only applies to yourself and a small minority with a similar physique. Similarily here, going with your gut is either good or absolutely horrible advice — depending on what someones gut tells them.

If you look at the history of violent crime for example, most of it was based on someone's gut feeling.

If you're the type who does a lot of overthinking and in hindsight could have just trusted your gut, it might indeed be good advice, if you're a bundle of bad impulses controlled by a thinking mind, rather not.

And advice that is not generally useful to all, should always be given with a caveat
"Please note that normal charges for CDN bandwidth are billed separately"

Compared to cloudflare workers, which has free bandwidth, bunnys bandwidth is not that cheap at 0.01$/GB

So while their example suggests stream-encoding video is possible, it would probably be cost-prohibitive.
Politicians are normal people. If you don't trust anyone to do the job you can apply for doing it yourself.
I’ve definitely purchased Sudafed in Seattle with a Virginia Drivers License.
I've noticed that in the UK all phenylephrine based OTC medications also contain paracetamol (acetaminophen) and often caffine. They are just an expensive way to buy two very cheap compounds with an added bit of placebo effect from the flashy packaging.

I can't take pseudoephedrine due to high blood pressure and I've found that the most effective thing for me, especially at night, is paracetamol, a blast from a nasal spray, and one of those nasal strips that help keep your nostrels open a bit more. It's not quite up there with the real Sudafed, but it's generally enough to get me a good night's sleep.
True except it is definitely more effective than saline. Phenylephrine nasal spray is not as effective or long-lasting as oxymetazoline, but it's also not as dependency-inducing.
It seems like you’re in a community in need of this; you can be the organizer! You seem like you’re in a small enough community to not even need a permit! All you really need is a clear space and some music. Throw some adverts up on insta and some telephone poles and you’ve got yourself an event :)
Why are you mentioning 16 year olds when that's not really included in the definition? Latchkey is when grade school aged kids are left alone during the gap between when school ends and parents return from work, sometimes hours later. Older teenagers are basically allowed to be home alone indefinitely.
pseudoephedrine have serious side effects, they are rare but could be fatal
Yup, I have two perfectly good iPads sitting in a drawer nearly-unusable for modern online things because Apple and the web have left them behind (and all apps that have online services are no longer functional of course). The hardware is mint, the battery is good, everything in tip-top shape, but... forced obsolescence. The actual CPU/hardware are absolutely powerful enough to perform all basic computing tasks including web browsing, but Apple would prefer I just throw these away and buy a new iPad (as if that's going to happen). It's really abhorrent to me that this borderline-godlike technology is supposed to just be... thrown away after a few years? Like, I'm going to be blunt: what the fuck?
It's all way over my head, but this is amazing work! The 2 obfustication techniques are pretty insane.

> He has treated every woman in his life like trash

This is a lie.

> he is pretty explicit about which kinds of immigrants he doesn't like; the ones from south of the border.

This is a lie.

We're tired of your lies. Do you not get it? When will you get it?
Absolutely not.

I want to keep the legalese in my setups at a manageable level, avoid needless lock-ins (AGPL is one of the least compatible licenses out there, code from an AGPL project can only ever be used in another AGPL project) and have it be clear when I contribute to a proprietary project in disguise (which most startup AGPL projects are, thanks to CLA:s) and when I contribute to an actual OSS project
Usually the timing rules aren't the same for TAS and RTA, as TAS timing always starts at console power-on while RTA usually when 'new game' is selected from the menu.
Actually, its not. IQ is normally distributed because it is a statistic explicitly transformed to be normally distributed with respect to the population.

But intelligence itself is more like exponentially distributed. Think of a chess grandmaster versus a range of people of various ability. What does the distribution of winning odds look like?
15 years too late (since you last snatched QNX away from us), and with a license that you can revoke at any time. What are you blackberry folk smoking?

I guess your "benevolence" is no coincidence given that real-time support was merged into the linux kernel a month ago...
I think you missed the word “before” in their comment.

Miss a mortgage payment and the mortgage holder will try to contact you through many channels. If that fails and you keep missing payments and they decide to evict you, that process takes a while and will include even more attempts to contact you including printed notices left at your house.

Miss renewing your domain and you will probably get email from the registrar about it, but if you didn’t have the foresight to set up a filter to whitelist those it might look like spam and you might miss it. You then only find out when your domain stops working.

Also mortgage payments are typically monthly. When you have to do something monthly it is a lot easier to remember than things that are yearly, especially yearly things that aren’t associated with a holiday or other special day.
The definition of science has changed quite a bit over time.

To frame the problem we would need to figure out what came first, the scientist or the definition.
Put them both in the freezer overnight?
>The point was that the response is also a packet

Sure, which is why it's useful. If the response doesn't get back it's not a reliable route. It seems like you're saying tracert is bad because of some sort of circular reasoning where you've decided it's bad so it's bad.

Germany or France didn't go to the Iraq war as a part of the "coalition of the willing", and said would vote against it in the UN. If Poland tried doing that to the USSR, there'd be a huge risk of Russian tanks in Warsaw and a government change. In fact, almost all major decisions Polish authorities made had to factor in the risk of Russian backlash and invasion. For example, they decided to institute martial law in 1981 and squash Solidarity, because they the alternative (Solidarity squashed by Russian tanks) would be much more bloody.
A sign-language educated ape invented "waterbird" when it saw a duck. Why are English speakers looking elsewhere for compound words?
You usually use them for compute and low-bandwidth related activities (like an API).
You don't get a Swedish license if you don't turn your head when switching lanes. It's weird that the country of driving has so low requirements and quality of driving
I wish I would see in other countries this same new reach on new channels and new media, but I just don't. It's almost like only neonazis know what a tiktok is, while the very few historical parties members trying it are stuck at "fellow kids" approach. Not even on Facebook, called home of the boomers, are they even trying. I'm sorry but I can call this only stupidity, fully agree with your points, and hope those folks learn the new lessons as well.
Satelite still is centralized, needing a core to handle billing and routing. In time of war, it is quite easy to disable, and it remains fragile due to complexity, whilst being in someone else's control.

HAM radio is robust, has no outside dependency, and is fully in control of people using it. You just need to have the equipment, no ifs or buts.
Horrible UX, disabled in `chrome://flags/#top-chrome-toasts`
i'd love to see some grassroots-powered clandestine para-web running at least partially on radio. obviously such a project would either immediately or at some point face the usual issues like: spam, cp etc. that's why i believe such a network would have to be slow. it would have to be so slow (and just fast enough) for text-based communication and simple protocols. and i mean text as in < 1kB ... not sufficient for transmitting sth like base64(videoclip). that would be so cool.
Cloudflare DX is garbage. It has improved a bit in the last year but it's very far from being usable by your average developer. I am building a product on workers and I am questioning that decision every other day.
>> If you say that all hells are made equal, I won't agree

>Not how a discussion works.

So you do say that? Can I ask you something? Where would you rather be: in the fire-bombed Tokio or anywhere in the Ukraine now?
The point of a product manager is to make a lot of decisions that don't have a clear answer. "Should we use websockets or REST for our chat client?" - easy technical call. "Which market segment should we target with our features?" - not so technical.
Dorian Yates (former mister Olympia) claimed he trained 4 times a week for 45 minutes while preparing for the contest. But very intense training.
gcc was specifically designed to not have many reusable parts to avoid people ripping them out. modularity only happened after LLVM and clang specifically started eating its lunch.
1, $100: Fenix LED headlamp, 1200 lum, with red light, made from lightweight magnesium alloy with magnet, waterproof. I use it almost daily, for bike, for work, for reading (red light), camping...

2, $1000 E-reader (Onyx Boox). I never read that much before. Ability to highligh text, make notes by pen and have it in readable, indexable format is something that I miss on paper books.
Probably also depends on timing and the type of training.

I started with 1 hour of extremely intense cardio. The first 40 minutes you can go through before the sugars from the oatmeal start to hit, but starting around that 40 minute mark, the real burning of your body stored energy starts to kick in and you can realy feel those flows. The next 30-60 minutes I did high rep but relatively low intensity strenght training. This is what the oatmeal was for.

The idea of the high caffeine shots right after training just before the sauna was a hack to make you want the training more. You mentaly fuse the caffeine addiction reward into the workout routine so your brain craves the workout.
> Do be aware of the need to use sterilized water to avoid a possible dangerous infection, though. Distilled water is the easiest way.

It must be noted that the infection is incredibly rare and requires multiple conditions (like dysfunction of the immune system, unsafe tap water...)

- https://en.wikipedia.org/wiki/Naegleria_fowleri#Pathogenicit...

- https://charlotte.floridahealth.gov/newsroom/2023/03/DOHChar...

For example here in France tap water is disinfected with chlorine and hot water must be heated to at least 50°C which is enough to kill the microorganism.

On the other hand, depending how the distilled water is sourced (container bought in a supermarket...) & used (opened/closed daily...), it can actually create a much riskier source of infection.
You could also promote nature-friendly lifestyle and support vegetarians somehow.
Ask HN: How you can shop on Instagram?
Hey HN,

Just two questions

1) Will you use Instagram for shopping where you can shop directly from a reel or post of product without leaving the app?

2) Would you use a social media platform specially for commerce where you can buy products from brand's posts and short form videos directly without leaving the app, where you can find user generated content, ratings and reviews?

As buyer or seller

Share your thoughts would help me a lot

Thank you
Good luck certifying an automotive or an industrial system that can lead to loss of life or severe disruption if it malfunctions. As far as I am aware, QNX, VxWorks, and CMSIS have all been used in systems that passed certifications. As IoT &co. get applied more broadly in our society, they are put in more places where they are expected to function flawlessly. I would rather want my power grid or water utility operator to use CMSIS, for example, than rt-linux.

The only serious user of rt-linux which uses it to build a hard-RT system that I know is SpaceX. Look up the Reddit AMA post from them on how rt-linux is used. They are staying on a specific kernel version, had to do kernel patches (other than applying rt-linux), they use a very specific model of an old Xeon for low latency interrupts, incorrect programming of one process can disrupt the RT behaviour of another process, and most importantly, they have a secondary board, a truly real time one (PowerPC based, IIRC) to communicate with the real hardware.
The edge means it's stateless (not serverless) and running on multiple servers, so serving the customer from the closest one (at least in theory).
Also true of aspirin, ibuprofen, acetaminophen, dextromethorphan, melatonin, vitamins, supplements, and practically every other over-the-counter drug that is not homeopathic.
You're right that the simile starts falling apart when you look at it deeper, but on the whole I think it does provide a reasonable example: when you can experience international travel and business opportunities in your mother tongue it is less appealing and more difficult to learn another language. And this is what we see from French-speakers vs Finnish-speakers. Yes, French is much more global than Japanese is, but the end result is the same: if you speak French or Japanese, there are many more economic, cultural, and travel opportunities available without needing to learn a L2 than if you speak Finnish or Dutch or Hungarian. That's part of speaking a language with 100+ million speakers compared to 5 million speakers.
Ask HN: How do you switch between your phone and your PC?
My digital life revolves around my Android phone and Windows 11 laptop (and then Linux servers, but this is irrelevant to my question).

My main problem is that when I start something on the phone (usually a web page) I do not have an easy way to continue on the laptop. I end up sending myself emails or "pushing" the web page on the laptop (using the "share" function or Pushbullet - either works from time to time).

The other way around is even more complicated.

How do you manage that?

Do you use an app to take over the phone on your laptop? I tried in the past to join my phone with Windows but the experience was very bad (the phone had to be constantly unlocked, some apps were not working, ...)

Or do you have a set of micro-services that each do their thing? (sharing a file, sharing a URL, ...)
This was an election on the US economy. And for many Americans the economy sucks
I wouldn't call Go a 'server side' language. The Go compiler is written in Go, for example! Cross compilation and (relatively) small binaries make it super easy for distribution. Syntax sugar is a fair point though, it doesn't lend itself to functional-y pattern matching.
A tool like this is probably a great way to get some VC money.
