## Solving a 1993 Programming Challenge in 2022 (Updated)

I recently came across a collection of old (1990s) “programming challenges”. I thought it might be amusing to tackle one of these challenges using technologies from the period in which they were posed, and compare the solution to one using contemporary techniques. In other words, do the same problem in C and Python.

## Unix Tools Today

I learned Unix almost 30 years ago, while attending graduate school in the early 90s, from a now long-obsolete book entitled “Unix for the Impatient”.

Some of the tools and commands I learned back then have long since become irrelevant (ftp, telnet, cvs, biff — remember biff?). Others, although long in the tooth, continue to serve me well every day (emacs, tcsh, cc). And yet a third group seems to be more important than ever (such as tar, which is the basis for Docker images).

## How Has Software Development Changed?

A survey published by O’Reilly regarding the state of the tech industry made me reflect how the field has changed since the dot-com boom (and bust) — that is, in the last 20 years, which really constitute the Internet Age and the Modern Software Era so far.
