I've updated the hidden services to v3, here is the new link.

Endware Hidden Service

http://4zrrnwrjkedzhvh7z5lxph45tmmfzxvnha6435sgrefrfwyn6kav55qd.onion

All that is required is to add this line to your torrc below the line stating where the hidden service directory is

HiddenServiceVersion 3

and restart tor.

I can update the Secure Computing Practices Links page to v3 if requested. I haven't heard anything about that project in a while.
