Costs money to maintain and build correctly, which naturally leads to buying existing solutions.
- LinuxBender 4y agoI've heard that too, but I think it would take a decent developer 1 hour to make a first pass at such a thing. It doesn't have to be complicated nor perfect. I think it should not require images nor javascript. It should probably be a server-side LUA script that caches the puzzle and answer. I found a few starter ideas [1][2] and concepts [3] but I would prefer to use something like figlet vs gd generated images. Figlet or something like it should be much lighter weight. I just have to find one that is readable on cell phones.

- Filligree 4y agoI've seen a couple sites that do this. One of them just asks for the square root of -1! And sure, qntm.org isn't nearly as big a website as HN, but I concur that this isn't likely to be super-difficult. The wide use of recaptcha seems like mostly laziness; most websites aren't big enough to get targeted attacks.
