Some captchas are getting pretty discriminatory, not everyone lives in the West and can identify the objects they are asking you to. Another recent one sticks out where they asked me to pick a shape as the same number of conoids on screen. If you ask people on a street what a conoids I bet a significant amount will give you blank looks

Also at least now I know some people call those markings crosswalks

Sorry I live in the west, what's a "crosswalk"

Did you mean to say

> not everyone lives in the USA

Other things I don't have a clue about - a fire hydrant, yellow taxis, yellow buses

(Obviously I do, because of American cultural imperialism through things like Captchas which mean the world has to understand American cultural touchstones)

Also, if you use a larger minimum font size often the text describing the thing you are supposed to select is under the image and unreadable. With hCaptcha it varies depending on the size of the popup window with the captcha and Google seems to reliably show just the top (barely enough to figure it out most of the time).

But on the internet the answer to „what is a conoid“ is just a web search away.

The bigger problem is when other options of a captcha fit in another cultural context.

Taxi colors are an example for that.

In many countries fire hydrants are underground, under an iron or concrete cover. There's very little to see on the street.

There might or might not be a sign marking the location.

If you think you're failing the captchas because you're doing them wrong, think again. Google captcha intentionally fails you a couple times if they don't have enough tracking info to determine that you're legit. So you solve the captcha correctly but are still lied to that "you've failed to solve the captcha, try again".

That and the "fading images slowly to pretend like you have bad internet" thing. Disgusting behaviour

I distinctly remember a captcha which asked me to identify fire hydrants. Some of the pictures were hydrants, while others were standpipes. These are different things, and I answered accordingly.

The service refused to acknowledge my humanity until I relented that a standpipe was a hydrant. If at some future date any of us burn to death due to an automated fire truck that misbehaved due to this, we’ll know why.

Unfortunately, even understanding these things, on a shared connection it might take you literally two or three minutes of captcha work before Google recognizes your personhood.

Am I identifying the boxes wrong? Am I doing it too fast? Where do "Stairs" begin and end? Does a motorcycle include its rider? Or is Google just fucking with me and failing me on purpose?

My workplace had a period this year where captcha was put into the cashier checkout process.

Yup - I recognize this problem. I am a motorcyclist and I frequently have to grit my teeth and misidentify scooters as motorcycles if I want to get past captcha.

For non-bikers, a scooter has an automated gearbox and small wheels etc. Think vespa.

In the UK at least they are generally a different category of license, although that's because of the size of a standard scooter engine.

I kinda don't understand why we still have captchas. We've solved the asymmetric problem with proof-of-work; just make somebody solve something trivial so they spend more resources than you do.

Like if a bot requests your page 1/day its not a problem; but if they want to request it 1/ms then the proof-of-work becomes too much for them and its transparent to a person.

I am Googling "conoid" right now and I still can't even imagine what it's supposed to be.

The Google dictionary says it's a zoological term "approximately conical in shape".

The Wikipedia panel says "In geometry a conoid is a ruled surface, whose rulings fulfill the additional conditions: All rulings are parallel to a plane, the directrix plane. All rulings intersect a fixed line, the axis." The graphics are... nothing intuitive.

The M-W link in the search results says "a cone-shaped structure; especially : a hollow organelle shaped like a truncated cone that occurs at the anterior end of the organism".

None of this seeming relevant, I clicked on the Image tab and it's all these complicated Mathematica-style graphs of things that are very much not cones.

I see other people in the HN comments similarly have no idea.

Can you please explain what you saw on screen? What did the captcha think was a conoid...? Like, traffic cones or something?

Even within the United States, fire hydrants vary greatly from city to city.

I remember the first time I moved to a city that had those little squatty dark blue ones. I thought they were water main access points.

It's interesting to see so many people on HN assessing that captchas are biased toward American culture. Very frequently I get captchas that include things I don't know, and when I look them up, they turn out to be Indian in origin.

Is a coach a bus? Honestly, I'm not sure what makes them different, if you pressed me I think I'd say a coach has luggage compartments underneath. A UK coach is not a bus... although Megabus run mostly coaches, and Stagecoach run mostly buses.

Is a scooter a motorcycle, what about a pedal-and-pop, an ebike? Is the backbox (rear carrier) part of the motorcycle?

Is a single light at a junction, ahem intersection, a traffic light? Is the outer-container part of the "light"? What about the lights for pedestrians, are they part of the traffic light?

Are house steps, that don't carry you to a different storey, still stairs? Is a single step also stairs?

Are fire hydrants always red?

Well technically anything can be a shuttle because specifically the thing that makes it a shuttle is the operating pattern (repeated point to point service) rather than the machine itself.

Etymology-wise a shuttle was a type of weaving tool which is why the verb shuttle exists, i.e. to rapidly move back and forth across a length (as if you were weaving a thread into a piece of fabric).

So then you got shuttle trains which frequently ran back and forth. And from there other types of shuttle services (shuttle buses, shuttle vans, etc).

And of course eventually the space shuttle being intended to be a launch vehicle designed for shuttle service to and from orbit. (side note but technically if the SpaceX Starship actually achieves it's intended sub-24h turn around it'd be able to qualify as a shuttle provided it ran a fixed point to point route on a regular basis).

Presumably an American motorcycle purist's brain would simply explode in such an environment. :)

Can you have them translated into your native language? I mean I imagine if your using Google from a different country, it might take notice. Maybe it doesn't apply to reCAPTCHA, Google can be stupid like that!

I like it myself. If I have to use CAPTCHA that is, I can't stand it on principle!

Similarly, on websites that require a British address I use “10 Downing Street” (the only one I know!)

> Are you allowed to park at junctions in USA?

US driving laws vary quite widely depending on the state (and sometimes depending on the city within the state). So there’s probably no uniform answer. But parking at an intersection is indeed allowed in a lot of places within the US, in my experience.

This doesn't look like a surface with stripes at all.

Classic Vespa does not have an automatic gearbox. Last one without it was probably a PX model in the early 2000s, though.

Of course as a scooter rider you say its a motorcycle. That wiki entry was probably written by a scooter rider also. ;-)

I actually feel a fellowship with all two-wheel riders but don't let any other bikers know or I'll be shunned.

In the UK some crosswalks have cones on the bottom of the box where the button to wait to cross is, and OP mentioned crosswalks in the final sentence. Maybe it's just too late for me right now, but that's what my brain assumed, but the "same number of shapes as" thing was not enough context!

the cone on the bottom spins when you have the right of way.

Well the local long distance bus "consortium" did move at least part of parcels via busses here.

Where did you get stripes from in any of that? A surface is ruled when it can be constructed by extruding a line (or segment) along some path… like waving a ruler around.

This can't be right, I have been told over and over again that America does not have any culture.

Now it's being used to push imperialism through captchas of all things?!

I feel like all the non-US or non-Western or however you want to categorize the 'rest of the world' should be striving to use free-range local culturally-appropriate captcha services if this is true.

It's easy to blame the colonizers, but what about the local artisanal websites who give the colonizers/invaders a voice by integrating their captcha services?

We really need an 'international-divorce' to put these issues to bed once and for all.

The "decent reasons" just sounds like snobbery or a reason to feel superior. Cars are cars, whether manual, automatic, CVT, whatever. Why should bikes be any different?

I'm a big fan of two-wheeled transport in all its forms, but wow is there a prevailing toxic attitude among a large group of "true motorcycle" riders. Instead of welcoming people into the fold, it's just tribalism -- you drive a scooter, you're not a true biker; you ride a cruiser, true bikers only drive super sports; you drive an e-bike, but only loud pipes make a true rider!

I think they meant that something striped and rectangular, like a crosswalk, is a 'ruled surface' because the stripes themselves are like the ruler ?

So I guess a crosswalk (flat rectangle in 3D space), would be considered a 'ruled surface', but I don't think it meets the other requirement to make it a conoid.

Agree about the snobbery, but there is a real difference in kind between them that would be nice to have a good name for. Even if, as the other reply pointed out, they exist on a spectrum, the endpoints are pretty distinct.
