# This Dockefile demonstrates how to install upstream pypy3 on a bare Debian 10
# box from scratch.
#
# To test:
# docker run --rm rjw57/pypy3 \
#       pypy3 -c 'import numpy as np; M=np.array(range(16)).reshape((4,-1)); Q, R = np.linalg.qr(M); [print(x) for x in (M, Q, R, np.dot(Q,R))]'
FROM debian:10

# Install any system-wide dependencies we need including essential packages
# required to compile C-based Python modules.

"""
A plugin which contains a custom Ansible filter named "friendly_hostname"
which takes a string and generates a deterministic human-readable hostname
with a low chance of collision.

The generated hostname has around 24 bits of entropy which is probably OK up to
a few hundred hosts. See: https://en.wikipedia.org/wiki/Birthday_attack

This module may be run via "python -m friendly_hostname" to test the generator.
