If you're in trouble and cannot find an answer to a question which goes beyond Stack Overflow...
If you have a not-so-usual solution for your problems but need to justify it to your boss...
If you like to think on your own rather than blindly follow "common wisdom" and "profound truth"...
...then 'No Bugs' Hare on Soft.ware might be the right place for you.

Bot Fighting 202. Time-Based Protection

Quote: “Whenever we detect that the time spent within a piece-of-non-blocking-code, is more than a few seconds – then, either the system is hopelessly swapping, or we’re being debugged”
Another Quote: “What if we send not just a challenge, but a “challenge which includes some piece of code to be executed on the Client-Side”?”

Bot Fighting 201: Declarative Data+Code Obfuscation with Build-Time Polymorphism in C++

Another Quote: “As we’re not writing our obf<> classes manually (instead, we have a code generator doing it for us on each build), the sky is the limit to the obfuscations we can generate.”
