Did you spot a fish? Press the Fish Doorbell (visdeurbel.nl)

I was born and grew up in sight of this lock where the fish doorbell is, 61 years ago.

I never knew we had this many fish swimming by until this camera perplexed me.

My boat was moored 30 meters away.

My ISP offices where a little further upstream.

2000 Years ago the city of Utrecht grew around this river branch, now called the Kromme Rijn/Vecht but originally it was the main river Rhine. It started out as a Roman frontier fort at the river crossing.

The Oude Gracht is the second most famous canal monument in the Netherlands after the Amsterdam canal system.


Nice idea submerging a camera into an erwtensoep. Hey, I think I saw a rookworst swimming by!


This is the most Dutch comment ever on HN


Erwtensoep is called pea soup in English.

Actually this canal used to be a stinking city sewer and was less murky green than fecal brown for most of its 2000 year existence.

The fish came back when the sewage was removed in the last 35 years. The green color is from the healthy algal soup.

The stench in the summer was so bad that for hundreds of years the rich build beautiful country houses and castles in the woods east of the town.

Let's hope we don't see any 'brown trout' in there :-)

Seriously, though, I love a nice green algae for some good old oxygen.

I just saw some all along the shore of a small tributary at a local park that had tons of little (but not tiny) bubbles all over it. I thought it might be oxygen.

Such a lovely florescent lime green.


>tons of little (but not tiny) bubbles >Such a lovely florescent lime green

Quite probably oxygen from the plants and not methane bubbles.

>small tributary at a local park

Quite probably where I was a boy scout and had my first kiss



Unrelated but why did they have to highjack the scrolling on this page…


That's cool, but what I want is an ROV that will let me prowl around a lake or stream or the ocean and see what's in there.

Of course, not getting snagged on something is a problem, as is losing power, as is murkiness, but I'm not gonna build the thing -- I just want to use it.

I wanna see what's/who's down there!


I did see fish fly by so fast that it would be really tricky to snapshot them.


Me too, and then I pressed the doorbell but the page said "there's no fish in this image" (because it swam away), so I didn't send the photo. Am I supposed to wait for a fish that will hang out in the frame? It's a bit unclear.


Guess: It's not useful to open the door for a fish that is not (in effect) waiting around to get through, hence the additional "check image for a fish" requirement.


Yeah but I don't know what the place is like (or how big), so the fish may very well just be waiting around just off-camera.


Depending on the smell of the day the fish will hover (hang around, linger, float?) in the frame.


This is delightful.


How much would it cost to fine-tune an AI to recognize fish and do this automatically instead of crowdsourcing?

Maybe some one-shot object detection model would work even without fine-tuning?


"People do so enthusiastically every year. In 2024, the Fish Doorbell attracted around 2.7 million viewers, from America to Brazil! The project has gained global recognition, helping people worldwide learn about fish migration and Utrecht’s underwater world."

I don't think solving the problem is the goal, it's attracting attention while solving the problem, which is a different goal


*sigh*

"I want AI to do my laundry and dishes so that I can do art and writing, not for AI to do my art and writing so that I can do laundry and dishes."

This thing is whimsy and fun, it's not a chore to be automated away.


This is about teaching people about waterways and local wild life. Hiding it behind the an AI would defeat the point.


I bet it was a conscious decision to crowdsource it instead of automating it in order to get people more interested in the fish. It seems like it's drawing a pretty substantial fan base!


Eager to abandon your observation duties already? But you just got here.


I like watching cats more than cat food.


This would come into existence almost instantly if there was money to be made with pressing the doorbell at the right moment.


probably low, but then it would be boring instead of a community event full of whimsy and fun


This is more about community engagement and education than anything else.


Some of the very best moments of my life have come from those moments when I feel like I a part of something bigger than myself. Act in a play. Be the 30th person in a start up. Sing in a choir. Ring a bell.

It appears to me that far from enhancing these moments, in general the internet has inhibited them. The focus of our current internet is Me. Instagram where you can show people how beautiful you are. Facebook, where the important thing is what you like. And who you follow. Me. Me. Me.

So it seems natural that the "next big thing" is something that will make the internet even less hospitable for a sense of community - for the We. No doorbell, just an AI.

But maybe that is a good thing? This internet with all the tracking and lack of civility can become just a place where AI's can spend hours tracking and targeting other AI's. Far out!

We can build something else.


"It is the destiny of computers to become interactive intellectual amplifiers for all people pervasively networked worldwide."

JCR Licklider initially called it the intergalactic network, now know as the internet.

>We can build something else

Some of us tried (with internet fish swimming around) :

Far Out! Thanks.

We could use some Complex Adaptive System architecture to create galaxies. Or we could call them Gestalts instead of CAS.

In gestalts entities, use rules to interact with a read/write message bus.

Ants. Pheromone trails. Write when you find food, not if you don't.

We have the pieces for this. Entities - people. We have a r/w bus - the internet. What we don't have are rules. We can think of rules - the kind Wolfram talks about in NKofS - instead as a language. A language in the sense of Sapir-Whorf. "Twitter and Tear Gas" (Zeynep Tufecki) is a good illustration of Sapir-Whorf in internet languages. (Available as a pdf I think)

That language is the missing link. In Real Life there is a language for collaboration. Perhaps the task is to understand the elements of IRL collaboration and then transpose it.

One could make some guesses about fundamentals. As we have all discovered, one fundamental is trust. IRL Trust is identity and reputation based. With many caveats. Perhaps we could start by considering A New Kind of Identity. ?

$0 basically.

You can fine tune a YOLO model on a work station in an hour or so.
