Kill unkillable Groovy job

If a job is running a system groovy script, it cannot be simply "aborted"

You need to go to $jenkins_url/script and run the contents of the attched script, replacing the original job_line content with the path (from URL) of your job

"""
A Python decorator is a special function that can be added above a
callable definition (function, class, anything that implements the
`__call__()` method)

When a decorated function is called, it is in fact the decorator
itself that is called, and the wrapped callable is then normally
called by the implementing handler of the decorator.

A Python decorator is comprised of 3 parts:

Love2D.org/wiki downloader

The Love2D wiki is a great starting resource. Mostly I do small-time game development for fun, on long flights or train journeys, or out in remote places. Frankly, it's the only time when I am guaranteed time to not be disturbed for sufficiently long periods.

And so, I need the main wiki in local, offline, usable format.

This script is a considereate slurper which shouldn't DoS the server in the slightest.

Plot times examples

As a network behaviour demonstration, I did a repeated clone-out of a Git repository, writing its timestamp data with date '+%F %T' in columns one and two (start and end times) of a CSV

This Python script processes that CSV to produce a plot of the durations:

• timedeltas calculated using datetime
• plotting using matplotlib.pyplot
• adding labels at spaced out intervals, and rotated

""" Rename files

    rename-tracks.py TRACKFILE [apply]

TRACKFILE is a basic text file, each line containing a track name.

This script naively looks for the track name in each file name.
If found, the old file name and new file name are printed.

If a title matches multiple files, an error is raised.

Time Sampling

I was curious to know what level of precision I could get when using time.sleep(x), like, if it made any sense to try and sleep for say 0.0132 seconds.

It turns out, it does. On a Windows machine with a 1.6GHz processor, I get a sample rate such:

$ python3 time_sampling.py 6
Average step over 1000000 (100.0%) iterations: 2.77e-07

Quick one-off script to convert a yaml file to native python.

python3 convert-yaml-to-python.py YAMLFILE > my_data.py

A little naive, but a quick tool otherwise.
