Ask HN: Dynamically Created Content for Webpages
Hi all,

I've noticed, especially on the homepage of Chrome for mobile where Google recommends webpages, that some of them feature outdated content presented as new. For instance, a product released a year ago is highlighted in a post dated today. Interestingly, these posts often relate to products I've recently viewed on sites like Amazon or eBay.

I'm uncertain whether this content is dynamically generated or if these webpages deliberately post old content to attract customers.

Has anyone observed something similar?

> It’s not ok to let your five year old play with a soccer ball on a busy neighborhood street unsupervised.

When I grew up the road by my grandparents house was wide and empty and you could see anything coming a mile away and drivers could see the kids playing just as well.

Now it has been redesigned to be a cluttered mess to "discourage speeding" even adding parking spots to reduce the width of the road. You could drive through it at walking speed and still wouldn't see a kid trying to cross the road before it popped out from behind a car right in front of you.
Ask HN: Are there any websites for SQL puzzle games?
As a Python programmer, I often use Django or SQLAlchemy ORM and as a consequence, my proficiency in raw SQL remains at a basic level. However, I am keen on improving my raw SQL skills, given it's sometimes superior to ORM, and because I find SQL and relational algebra surprisingly fun to think about.

Does anyone know of websites that provide SQL puzzle games that allow users to solve problems by writing SQL and validating them? I believe this would be an engaging way to enhance my SQL skills. Your suggestions are appreciated!
Isn't that what they should be investigating? Are you trying to imply something with that question?

Where I live, everyone can buy bottled water in glass bottles. I think there are now glass bottles with Coca Cola, too, though I'm not certain (I don't drink soda).

The catch is they're obscenely expensive.
I think Occam's Razor applies here, which is to say an inexperienced and idealistic board got cold feet and tried to remove Altman on principle. They failed because Altman is not only a political animal, but also one with friends in high places. Can't remove the helmsman at peak hype cycle and expect no consequences.
As covered elsewhere in this thread this is a uniquely American issue. Sit down, we know we have a problem.
How is that even allowed to be called recycling? As in, is it genuinely a term defined legally and, if so, who allowed this to happen? Because burning is most certainly not recycling.
Vertical tabs are native in Edge? In any case, it has existed in Firefox for a long time before Edge even existed. But I guess you particularly like Edge's implementation. It does sound funny though that someone would prefer Edge because they browse a lot. Usually people use Edge because it's the default browser in Windows and they don't know any better.
You may look into Trivy [0] , works very well for me so far.

Chiming in to also state how absurd this sounds to me.

I live in a household with 3 adults generating trash, we don't even fill up a 190L bin every 2 weeks in between pickups, usually when I roll the bin to the street it will be about 1/3 to 2/3 filled. We have a compost bin about the same size which also gets about 1/3 to 2/3 filled every 2 weeks.

Apart from that our recycling bins (about 60L for the paper/plastic ones, 20L for glass and metal) gets filled in about 4-6 weeks which I then take to the recycling station.

In summary as 3 adults we generate in the absolute top end about 117 gallons of non-compostable trash a month (those are very rare instances), so about 30 gallons a week for 3 adults even when adding up all the recycling we do.
I arrived to the conclusion that this "risk-aversion" in child rearing is basically the result of smaller families. This may sound callous but I think parents are much more OK with their oldest son/dqughter taking bigger risks if there are other 4 ones at home than if that's your only child and losing him/her is the end of your lineage. Not saying that more kids work as a genetic backup, but I think that for sure that creates a subconscious effect in the parents' risk assessment.

I read somewhere that propensity to war is proportional to the average age of a society. I think the same phenomenon applies to acceptance of risk in child behaviour but now related to fertility rate.

> That's why in UK we have banned construction of Wind Turbines on land, we have banned construction of solar panels on land of 'potential agricultural value', which is basically anything except mountainous terrain.

I think that ban has more to do with the current party of government being the Conservative Party, who like to imagine the natural state of the whole UK being just like the gardens of a Victorian era country house. For the sake of everyone not from the UK, this: https://en.wikipedia.org/wiki/File:Harlaxton_Manor_-_Univers...

> I have entirely lost faith in the anglo-speaking west as a force for good and progress in this matter.

You're not alone. Weirdly, even it seems that even Conservative MPs don't have much faith in the Conservative Party right now.
Let’s not forget the role of lawyers and the general increasing litigious nature of society.

Something that improved developer experience by far and also sped up our builds is starting the container dependencies via docker-compose and connect to it for integration testing. This allows reuse of containers, you can connect to it after/during an integration test to debug without having to keep searching for ports constantly.

With TestContainers - I've perceived that running integration tests / a single test repeatedly locally is extremely slow as the containers are shut down when the java process is killed. This approach allows for this while also allowing to keep it consistent - example, just mount the migrations folder in the start volume of your DB container and you have a like-for-like schema of your prod DB ready for integration tests.

I've found the https://github.com/avast/gradle-docker-compose-plugin/ very useful for this.
Fairly small deficit (quarter to half an SD). It doesn't mention controlling for depression, which will have a large effect on cognitive performance.
Rocket engines are much more efficient at lower atmospheric pressure.

The bigger the nozzle the faster the exhaust gas. Efficiency is proportional to the square of the speed of the exhaust gas.

The bigger the nozzle the lower the pressure of the exhaust gas. If the nozzle is too big then the atmospheric gas goes into the nozzle. That’s the limit on nozzle size for sea level launches.

Starting high is better because you can have a MUCH more efficient engine.
Ask HN: Stick to Embedded dev or switch to Web dev?
Hi, I need an advice from experienced developers.
I have a master´s degree in electrical engineering, I am 32 years old and based in Europe, and I have 6+ years experience in Embedded software development. In the last 2 years I switched to independent contracting cause I want to work independently and remotely from my hometown in south Italy :). With my current client I now reached 100k+ euros and the possibility to work remotely 80% of time, while remaining 20% I have to fly to Austria to spend some days on-site. With this solution I can save lot of money at the moment, but looking at the future I am scared that I won´t be able to afford this lifestyle if I want to have a family and a more stable life in a place, specially because I feel like I had some luck with this specific client and I won´t be able to reproduce the same working condition in the future.

I love working independently and from remote, That´s why I am considering switching to web dev. where freelancing and remote work are much more popular. I have some basic experience with Web thanks to a job platform I have created, that´s why I think I´d really enjoy working with web stuff but I feel like I am throwing away my domain knowledge in embedded and restarting from scratch.

Given my need to work remotely, my path (and that of course earning good money is always appreciated :)), What are you suggestions?

Should I switch my career to web dev or stick to Embedded and continue growing my experience and dictate my working condition?
So maybe the German "Erfahrung" does not map 1:1 to the concept of "Experience".
But maybe it is not so much a lack of concept in the language, but something that is related to particularly American hire-and-fire culture, where every employee is an easily replaceable cog in a machine, whereas I think that the full depth of many tasks is not easily conveyed in a documented standard operating procedure, but often needs the actual experience in doing things often. (This is of course an over generalization, because we seldom hear form the established well run smaller companies. You hear much more about dysfunctional companies and dissatisfied employees on the Internet.)
> some position that isn't even talked about.

There are already lots of sibling comments saying the heavy use of plastic is "forced on people" by companies, so yes it is talked about. And that's exactly what OP implied.

I'm not even saying this point is entirely false, just want to emphasize that people actually prefer convenient things regardless if it's forced on them or not.
Which is a shame because it's the most fun part of the F1 engines to me.
> because of their inconvenience

IMO it's simply habits

no one would buy beer or wine in a plastic bottle, because it feels wrong (and it is if you ask me).

Here in Italy nobody in their right mind buys tomato sauce in plastic bottles, our granmas would come to haunt us at night if we did.

but we buy water in plastic bottles ¯\_(ツ)_/¯
> Open AI's Sora is not out for public use yet. The website just shows random video samples from OpenAI.
Its not unheard of for intelligence agencies to create and exploit weaknesses.
I think home batteries are still absurdly expensive for their capacity. The most efficient storage would be for you to buy an electric vehicle and use its battery.
> It's the idea that we can still use fossil fuels as long as the carbon dioxide emitted is captured and stored in the ground.

What? There is already too much CO2 in the atmosphere for humans to live healthily. Fossil fuels have nothing to do with it; we will eventually need to develop technologies to reduce current CO2 levels no matter what.

I don't like the narrative that carbon capture is bad because the fossil fuel industry is advocating for it. Yes, they're doing so for the wrong reason, but that doesn't change the fact that it's an area that desperately needs lots of funding and research. The sooner we develop it the better.
> Undocumented workers do work in farm, janitorial, restaurant, construction, and other sectors that is irreplaceable through any other reasonable means.

There is a fairly obvious reasonable means: Issue them work visas. But there is no lobby to do that because the people doing it prefer the status quo where they're cheating on their taxes and getting out of regulatory requirements companies who hire US citizens have to follow.

Enforcing the law is the best way to get the law to change.

Here's an article: https://newrepublic.com/article/179267/recycling-doesnt-work...

The gist: similar to Big Tobacco, etc., internally with the plastics industry, there seems to have been a much greater degree of pessimism about the long-term economic viability of plastics recycling, but it was sold to the public anyway via ad campaigns and lobbying to forestall regulation or legislation limiting plastics as public sentiment was shifting towards a greater sense of environmental awareness.

It depends on the region you were born in. I was born in the country side of normandy where there's plenty of horse breeders. Some primary schools there will bring the kids once a week to do horse riding and seeing horses is somewhat common (plus there was always at least one kid whose parent bred horse in the class who'd invite his classmates to see the horses).

Outside of regions with horse culture, it's definitely a rich man's hobby.
I guess it depends on what you find compelling. I'm not interested in finance. A lot of it just seems like moving money around to make wealthy people wealthier. But it does make sense that a lot of heads will perk up if there's a potential for speeding up market simulation models.
I'd second the recommendation of An Introduction to Thermal Physics by Daniel V. Schroeder if anyone is looking for an undergrad level text. It is on my shortlist of "best undergrad textbooks read". It is also physically quite a small book; the quantum physicists must have some insight into density.
The speedup from the approximation wasn't that much if anything. He made his real improvements elswhere. But your point stands that memory speed really has moved the goalposts on what is feasible to speed up through using precalculation tables and if you can do it with math then that is often much faster.
This reminds of the "no kids zone" concept in Korea [0].

When first hearing about it sounded just a bit extreme, but the moreI read about it the darker and gloomer it gets, and it's a phenomenon that is having a deep impact on the whole Korean society's future.

Though transporting stuff large distances requires a lot of energy either way.
At that scale, probably. Especially since AWS would offer you discounts over their public prices too. Netlify et al probably stop making sense when they cost more than a few engineering hours and the cost of AWS, Azure or GCP
Indeed. While this requires them to do more with long distance power transmission, they are, in fact, in the process of doing more with long distance power transmission.

In the meantime, they're building more of everything else, too.

So… a mixed bag, really. There's good stuff and bad there, on the energy front.

Worth a shot if anyone can help me out / is facing the same problem.

I'm a US non-resident (from the UK) who registered a business via Stripe Atlas, and used Earth Class Mail (a Stripe Atlas partner) to setup and incorporate my company when I signed up to Stripe Atlas.

Due to the nature of my business, a large majority of payments are micro-transactions, so I spoke with a Stripe employee who kindly enabled micro-transaction pricing on my account.

Fast-forward to a few months ago, and I decide to offer a subscription service for my business at a higher price point. I was advised by a Stripe employee to set up a new Stripe account for these higher priced transactions as micro-transaction pricing wouldn't make sense, so I registered a new US Stripe account using the exact same business details as my Stripe Atlas account (using my Earth Class Mail address, EIN, etc.)

My original US Stripe Atlas account seems to have passed this new US verification fine - whereas my new US Stripe account is threatened to have payouts/payments disabled on March 12th unless I provide a physical US address, as it doesn't like the Earth Class Mail one.

I have contacted Stripe customer support who have not been helpful - if there's anyone at Stripe who can help me with this I would hugely, hugely appreciate some help.
Anyone who has actually worked or lived with people with Down's Syndrome knows that's an unrealistic stereotype.

People with Down's are have individual personalities, just like anyone else.

My daughter has Down's, so we're familiar with several other people with Down's (through support groups, sport groups etc). I can assure you, they are all very different, and this idea that everyone with Down's is happy and smiley all the time needs to die.
I’m afraid this is also a case of ochre-tinted helm — girls will bully each other even if their liege lord fully equips them.

I love the ideas behind what they do, but it'll take a long time before I trust any of those companies again. Back in 2018 I made a reservation for a Powerwall, and after waiting a couple of months and not hearing anything back, I've written a request to have the reservation fee (500EUR) returned to me, once every 6 months or so, without hearing back from a single person ever, even after writing multiple different email addresses.

That they can't agree on the pricing for a dish model doesn't surprise me a bit, they seem so disorganized even in their public marketing.
It seems like just supply and demand based pricing. Raise prices when you have more customers than capacity, lower it to meet growth targets.
Tires, metals, lubricants, plastics.. How is a bike more environmentally friendly? Many bikes are made in China, so you have shipping and transport as well. Have you ever visited a bike factory in China? How about a tire factory? A horse ranch is infinitely more environmentally friendly.

I think it's a case of deciding to focus the innovation budget somewhere else. Claro on the surface level looks a lot like Go, and it's probably intentional. Crafting an unique syntax, making sure it's efficiently parseable, and nice to use is a whole lot of effort, and the solutions we have today in this space are basically fine.

Claro seems to focus its efforts elsewhere - the main innovation seems to be its graph-based multithreaded work scheduling which is a novel concept, and has major implications for program organization, just not syntax.
Orbit is not about height, it is about speed. You have to get to almost 30km/s otherwise you aren't in orbit and you fall back into the atmosphere.
My feeling is that Web dev is a commodity: embedded is a rarer more defensible skill set.

Being fungible has its pros on upswings and cons on market downswings.

I don't think that I've ever been paid for Web dev work per se, but I have done a fair amount of more specialist stuff including embedded and financial and have only been on other people's payrolls for a tiny amount of time, and with a variety of working arragements, over decades. So I think that you can stick with embedded if you want to.
I wouldn't say so. Valve's business is selling PC games.

Wine is not an emulator, and has nothing to do with projects as Yuzu, Dolphin, PCSX2 and others.
Plastic is a superior packaging material. It delivers superb cleanlines and posibility to use packaging gas(Nitrogen) in automated lines. Cleanliness is essential for shelf life, and many products have it now unheard compared to 80s paper packaging - only due to package. Amount of food spoilage prevented by plastic packaging is enormous, it is very sad to see this no plastic hysteria. Like seing dark ages returning.
Human empathy is not a new thing. The behavior you describe would be entirely dependent on culture. You could easily imagine a culture where people with down syndrome were venerated as a gift from the gods. Outside of these extremes it's entirely plausible that members of the tribe who needed to be looked after were simply looked after. Your imagination of all historical societies as entirely savage is incredibly reductive.
The last time I saw such numbers for impractical-to-recycle stuff like thins and foamed plastics, it ended up that the companies were just lying

Love these kind of animations

I have my own animation here - if you scroll down. You can see the parsing I do for an async syntax (scroll to the hearing named Definition) - you can edit the syntax and it reparses and displays the parsed output. Sorry for the mess it's kind of a place I work on ideas. Further down is my graph renderer.

I want to auto parallelize async tasks.

I am working on a multithreaded runtime in C which is incomplete but can communicate between threads in roughly 60 nanoseconds at 6 million requests per second or closer to LMAX throughout of 20 million requests per second at a latency of 90-120 nanoseconds.

In my learnings Mutexes do not scale.

I am inspired by bulk synchronous parallel which means threads synchronize in a rhythm without Mutexes and a lock free algorithm to do with semaphores and observation rather than mutability.

I run two io_urings in different threads - one thread does send and another thread does recv. One ioring is talking to an epoll instance for network buffer readiness with EPOLLOUT.This means sending and receiving is full duplex - you can send and receive to different clients in parallel. I call it split IO.

I plan to write up all my learnings soon.

My adapted HTTP server from the loti examples gets a throughout that scales with the number of connections I am at 7000 requests per second. I am not nginx.

I use mailboxes and double buffering for thread safe communication. Each thread can communicate with another thread through its mailbox. This is like Erlang.

I plan to add coroutines based on Marce Colls coroutines. I can deschedule a coroutine when there is an await.

> Throw a d6 seven times and the pigeonhole principle requires that a configuration will come up twice. The example is weakening your argument; it's still true that if you throw a d6 five times, you expect a configuration to come up twice

Even that isn't as strong as you could make it; rolling a die 5 times is basically the birthday paradox but instead of asking 30 people their birthdays to find a duplicate, you're asking 300.

In the case of life supporting planets though, it feels like we're trying to talk about the likelihood of rolling a given value when we haven't even determined whether the die has unique values on each face or not. If you're assuming that only one of the sides has a 3 on it, the interesting part is already over.

Do upper-class people have more children?
Adding two notes onto this hypothesis:

- I can only assume that if a kid doesn't have an older sibling "to keep an eye on them" the parents take this role, and parents tend to be more risk-adverse and responsible caretakers than siblings.

- I've never lived in the American suburbs, but they don't seem very dense. I know that, growing up in Mexico, the kid density was great. Some of it probably has to do with the fact everyone had siblings. Matching ages with nearby neighbors is more likely when there's more kids too. We were outside all the time, older siblings introduced younger ones to the crowd. Friendships were made, broken and fixed. Adventures were had. More than once we got into situations that I knew my mom wouldn't be happy about too.
