| # 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. |

| # coding=utf8 | |
| """ | |
| 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. |
