Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

# You're meant to read through this
# configuraton file rather than simply
# copying it to your home directory.
#
# There are some places where you're
# meant to uncomment something if you
# want to use it in your TMUX.
#
# I hope it's readable.

#!/bin/bash

usage() {
  cat << EOF
Usage: $0 [OPTION]... COMMAND
Execute the given command in a way that works safely with cron. This should
typically be used inside of a cron job definition like so:
* * * * * $(which "$0") [OPTION]... COMMAND

Arguments:

Integralist

Lambda: standard

# Creating a lambda
l = lambda { |name| "Hi #{name}!" }

# Executing the lambda
l.call("foo") # => Hi foo!

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

Introduction

I have compiled these notes whilst revising for the Oracle 1Z0-061 Exam - Oracle Database 12c: SQL Fundamentals. They should also be relevant to the 1Z0-051 - Oracle Database 11g: SQL Fundamentals exam. Revision was most conducted using the excellent and highly recommended "OCA Oracle Database 12c SQL Fundamentals I Exam Guide" by Roopesh Ramklass.

I have aimed to include include in these notes common "gotchas" and easy to forget functionality rather than documenting everything required for the exam. This can then be used as a quick refresher before walking into the exam.

The content is broken up into sections with each heading mapping to the relevant [Oracle 1Z0-061 exam topics](https://edu

Motivation

tl;dr I want to use Rust to program robots. Help me find the best core libraries to build on.

Robotic systems require high performance and reliability, but also have enormous complexity in terms of algorithms employed, number of subsystems, embedded hardware control, and other metrics. Development is mostly split between C++ for performance and safety critical components, and MatLab or Python for quick research or task iteration.
