Eelis has also written the IRC bot geordi. The bot "evaluates" C++ snippets by compiling them with GCC (or clang), executing the resulting binary in a sandbox and pipes the output back to IRC. It's heavily used in C++ channels on multiple IRC networks.
Apart from seeing IRC still being mentioned quite often here and in other tech-oriented places, and a bunch of nostalgic feelings, this might be the final thing that is going to get me to pick it up again were I left it like 10 years ago: no idea this existed, but seems really valuable. Linux/Windows client recommendations anyone? Servers?
I favour Hexchat. Freenode is where a lot of the hacking talk happens, but not all; irc.mozilla.net and irc.gnome.org are other possible networks you might want to visit for "serious business". OFTC is another network where e.g. Clang and Debian things happen.
Why would anyone release their work into the public domain, and at the same time, disallow their site from being included in the Internet Archive?
