I actually like poisoning them. Not to be malicious but I feel manipulated into training their software for free. "Oh you wanted to sign up for that web forum? Sorry, but you have to do some free work for us first" And if you think that it's somehow good because it's mutually beneficial to train AI to better the future of humanity, don't. That is what their marketing department wants you to think.

The value they're providing is to the forum owner, who has reduced spam-handling workload. So the forum is providing you value, you are providing Google value, and Google is providing the forum value.

Maybe you want to censor internally part of an image for privacy reasons. For instance, in my country you cannot use or publish children images without parents consent. The fine for doing that is way higher than your benefits even discounting bad press.

I'm not expert on this but what I'm seeing is that port 443 is serving up a response when jaruzel.com is requested on that port. While you may not be actively advertising that domain with https URLs, it is valid for clients to request one speculatively. There isn't a valid cert for that domain and for some reason for server is offering a different one. Presumably you need to unbind 443 from that host header name (thi…

So... I have an IP... that IP points to a router, that router port-forwards ports 80 and 443 blindly to a web server, on that web server is a bunch of websites. IIS knows which ones to serve to clients based on a) the host-header, and b) the port. jaruzel.com:443 is not valid, but because I run an older version of IIS[1], that does not support SNI, the cert is bound to the port, not the host-header. As such any domai…

Sure, but if the public has to provide Google with free data, we should make laws requiring Google to open source the entire ReCaptcha training set.

It's a bit disappointing, when caffe2 was released it was stated that mobile is a big focus, but things like this don't support mobile (even though some of this was demoed by FB on a phone).

FWIW we have some similar R-CNN models using this codebase running in the FB apps on iOS/Android with Caffe2 - with some neat bells and whistles (eg full execution of the compute graph on the device GPU where available via Metal/OpenGL). I’ll look into adding a mobile tutorial for Detectron if you’re interested.
