| Title: dta_to_csv.py | |
| Author: Andrea Pasqualini | |
| This CLI tool converts a Stata .dta file into a .csv file. Python3 and pandas | |
| are dependencies. It does not return anything, internally. It saves on disk a | |
| file with CSV extension that has the same name as the input DTA file. | |

This document shows the steps to export and then import again a private GPG key. I find this useful when I need to reinstall my OS. If the GPG key has not been compromised (e.g., theft), then this is a safe way of moving keys around.
First, obtain the ID of the private key.

| This function computes the horizontal and vertical lengths of a screen | |
| given its diagonal length and the aspect ratio. The system of equations to | |
| be solved admits a unique feasible solution in closed form. The system is | |

I am reposting this wonderful ReadMe file by @michaelstepner from his healthinequality-code repository. This provides a detailed set of coding guidelines for his specific research project. It contains references to Stata and Julia. However, I believe it also represents an extensive set of arguments in favor of best practices for managing and maintaining code. As Michael correctly points out, we Economists are lagging behind software developers by at least years, if not decades. While we do not need to use complicated command-line interfaces or sophisticated systems, we still rely on automation for our research. It is important not to excessively rely on technical debt, which would otherwise entail unbearable long-term costs. This ReadMe file explains how to do so and provides a set
