Reproducible jupyter lab notebook using the Nix package manager (including working plots)
# Run this file with with 'nix-shell --command "jupyter lab"'
#
# This file uses jupyterWith from https://github.com/tweag/jupyterWith which
# implements reproducible Jupyter lab notebooks. The killer feature of jupyterWith
# is that it allows you to get plots working with e.g. matplotlib or seaborn,
# which did not work for me with the regular 'jupyterlab' derivation in nixpkgs.
#
# Enable plots with the `%matplotlib inline` magic command at the top of the notebook.
# Alternatively, you can do the same thing with `matplotlib.pyplot.ion()`.

Automatically generate ansible tags of the same name for each role in a playbook
"""
This module implements an Ansible plugin that is triggered at the start of a playbook.
The plugin dynamically generates a tag for each role. Each tag has the same name as its role.
The advantage of this is that it saves you some boilerplate, because you don't have to wrap
all tasks of a role in an additional block and assign a tag to that.
Additionally, it works automatically when you add new roles to your playbook.
Usage is exactly the same as without this plugin:

rkrzr / UpperStream.js
Last active December 20, 2015 18:19
An example of how to use streams in Node.js. It gets a page via http, transforms the data to uppercase and prints it to stdout.
var request = require('request');
var url = 'http://www.site2mobile.com';
// Set both readable and writable in constructor.
var UpperStream = function () {
this.readable = true;
this.writable = true;
};
// Inherit from base stream class.
