Is your favorite programming language solving Project Eulers too easily? Try HARD MODE.
Solve each Project Euler problem with a different programming language.
Vagrant abstracts away the many compilers / interpreters / bribes needed to setup each programming language. So you don't need to sully your computer with hundreds of software development tools (unless you really want to).
euler-hard-mode$ cd problem1/
problem1$ vagrant up
problem1$ vagrant ssh
vagrant@precise64:~$ cd /vagrant
vagrant@precise64:/vagrant$ cat README.md
