G-WAN Captcha Decode
View captcha.md

G-WAN is a new free web server. They seem to be very proud of it, or at least just want to make a lot of money. Well anyway, in almost every sentence they write, they claim that they are 20% cooler than anything else. It feels a bit arrogant. I have to admit, I don't know a lot about web servers, so I can't speak to how good they are.

However, then I saw their Captcha example. I also don't know much about machine learning algorithms, OCR, and stuff like that, but I do know how to read pixels. I also know how to compare values with python :P

demo

They say the following about their Captcha:

use constant MAXWRITE => 2000; #biggest write we'll attempt
use strict;
use warnings;
$|++; # autoflush stdout
