What's 0xf.at?

0xf.at (or oxfat it you prefer) is a website without logins or ads where you can solve password-riddles (so called hackits).

This is a tribute site to the old Starfleet Academy Hackits site which has been offline for many years now.

Can I contribute?

You sure can. If you have an awesome idea for a hackit, send it to office@haschek-solutions.com and we'll gladly put it up and give you credit for it.
