PyPy environment

Download and build PyPy as described here. It will take about 1 hour of modern machine time. The pre-built PyPy archive does not have all the stuff we need.

Instead, I supply you with a powerful Linux VM in case you choose to work in the cloud:

$ ssh [email protected]

pypy binary is in your PATH. And PYPY env var is also set to the path of unpacked and already built PyPy sources.

Google Cloud SDK

There are two alternatives to start with the SDK:

1. install SDK locally;
2. use provided Linux VM in the cloud via ssh.

Note: everyone will get a separate index, ie. hacker02, hacker03, etc.

$ ssh [email protected]
