This is fun but quite literally the opposite of what a captcha should be. I bet a bot will be able to solve this far easier than my grandma ever could.

Have the CAPCHA require properly constructing a nonlinear programming problem to solve an optimization problem, where the requirements are not expressed in terms of the NLP and the human has to design it. Which would have the side effect of putting the bot makers to work on useful and hard problems to solve.
Good idea! To prove you are a human, mine three Bitcoin.
Spam and DoS prevention were actually the original purpose of Proof of Work. Hashcash, the first (I think) anti-spam PoW algorithm, was what Bitcoin's PoW algorithm was inspired by.

I am on a forum with like 20 other posters and bots were stopped by the addition of a call/response field. Nobody who wanted to register would forget the classic response, but no bot was going to be able to answer it without some pretty specific google fu
How does that work if you want to grow your hobby or group? And if it’s something between friends why not use a private whatsapp group or IRC
Speaking for myself, if was a little bigger than 20 members (around 100). The thing is that we wanted to keep the forum open to everyone, at least for the public parts. That's why I went with invisible tweaks (mostly just renaming fields) instead of a challenge.
But I could have came up with a challenge that anyone interested in our forum would have known. We were a rhythm games club, so a questions could have been "We organize a tournament for this game, in 3 letters". Anyone who heard of us would know it is DDR (it was our main event), and for those who didn't, all it took was a quick look at our website.
And even if it is just a hobby, you don't get the same thing from a forum compared to a WhatsApp or even a Facebook group. In fact, a few years after me and all the geeky admins left, they switched to Facebook, which completely killed the already dying online community.
Maybe nowadays we could use a Discord server, which does a bit more for a community than an WhatsApp group, and is more accessible than IRC, and saves history.
Another great thing about the forum is that I still have a backup from the time I still had admin rights, and I could bring it back to life on a private server with some friends, even though the club is now completely dead.
Memories are not lost, except for most of the external links (ImageShack...).

I recommend reading the description in the link that mentions that concern is acknowledged.

#95Hitboxes are off, headshots don't count :( Also, I was hoping for a full 3D FPS version with canvas etc.
> headshots don't count :(
And if count then they shall provide admin access I think.

Headshots in doom 1, the game that had auto aiming and no ability to look up originally? Also, fully 3d might make it slower to load in case somebody actually wanted to use this for real. I played a webgl doom clone once that lagged like crazy
Yes.
Doom/II/Heretic/Hexen were 2.5D. That makes it easier to run on a 386 with fixed-point math, BSPs, and efficient z-buffers without busting out single-precision quaternions and 4x4 transformation matrixes. :)
Interestingly, Rise of the Triad, based on a modified Wolfenstein engine, is semi-3D with elevation changing.
Auto-aiming in the vertical axis only, IIRC it shot randomly all over the enemy. Enemies only had so many angle sprites IIRC and weren't really 3D.

There's a much better treatment of the Doom engine in Michael Abrash's writings, esp. Graphics Programming Black Book Special Edition. Trivia: his assistant once mailed me a replacement CD-R of the CD I lost from the paperback edition. I lose everything. Hehe.
PS: one of my favorite profs teaching a graphics course: http://www.infocobuild.com/education/audio-video-courses/com...
This guy is hilarious and awesome for having a Monty Python question on a final exam: https://cs.ucdavis.edu/directory/matthew-farrens
Ran into Sean all the time at Ace Hardware. Also, he got busted for living in his VW in a parking garage. I love that guy. https://cs.ucdavis.edu/directory/sean-davis
Have to brag about awesome profs/lecturers.

Please show that P != NP to prove that you're human. (500 characters remaining)
Let the proof of P != NP be A, where A is a proof expressible as a finite bitfield. The proof requires induction over an infinite sequence of proofs. But there is no mechanical way to move from the nth to the "n+1"th proof. Plus, "Galois", Gödel, Reimann and other intimidating names. QED.

#99I failed this 3 times in a row as a human (I promise) on a touchpad.
Nice try, Mr Robot. :)

Have you encountered the CAPTCHA from this monstrosity of a company called Arkose Labs? I don't get angry but I was trying to redeem gift cards for an elderly relative and I was shouting and gave up. Not sure if I am allowed to paste links but search for "arkose labs reddit" or just the name of this company on Twitter. Or search "arkose labs san francisco" on Google and just read the reviews.
Easily the worst captcha there is, it makes you do the captcha 10 times (it says 10 to go after you do the first one) and if you get one wrong it doesn't tell you until the end after you've done them all, in which case you have to repeat it.
Seems like they are afraid of robots.
