I can only imagine how much worse they'll make the captcha after stuff like this picks up speed with the users all the while being ineffective against the bots.

I mean at some point ... the average visitor is dumber than the AI and your now just blocking dumb people

yes, we're creating websites that are gated by IQ tests. This isn't the way

The part about bad KerasTensorflow.js interop is classic Tensorflow. Using TF always felt like using a bunch of vaguely related tools put under the same umbrella rather than an integrated, streamlined product.

Actually, I'll extend that to saying every open source Google library/tool feels like that.

> The official TensorFlow-to-TFJS model converter doesn't work on Python 3.12. This doesn't seem to really be documented, and the error messages thrown when you try to use it on Python 3.12 are non-obvious. I tried an older version of Python (3.10) on a hunch, using PyEnv, and it worked like a charm. Amazing. And then people wonder why "just use python 2" is still a thing.

Do you have examples of "just use python 2" still being a thing in 2024?

Yeah, whenever i need to write a quick script and have no time to suffer "$library needs python 3.x, where x must be > $value and 2 is stable and does not change from under you. Which is what you want in a programming langiuage

It might be worth noting that this, including the harder version the op encountered, are not the hardest captchas that 4chan can serve. There is a still harder version which is sent to less trustworthy IPs. I imagine it would still be tractably solved with computer vision. This in part misses the point though, since 4chan has been continuously altering their captcha since it released, making it difficult to create a…

Datacenter IPs can’t even post at all, nevermind needing to solve a CAPTCHA. That’s why the accusations of “VPN shill” are usually wrong, as is the assumption of anonymity – 4chan is in fact one of the least anonymous sites on the internet. The optional username feature gives it a veneer of anonymity, but the strict IP requirements ensure almost every post is attributable to a residential internet connection, and reliably associable with other posts from that same connection.

Some datacenter IPs can post fine, mostly just not those belonging to any large hosting company. I would mention a list of ones I know aren't blocked, but, well, that might get them blocked.
