## The Diamond-Square Algorithm for Terrain Generation

The Diamond-Square Algorithm is the natural first stop for generating artificial landscapes. The algorithm itself is beautifully simple (more details below, and on its Wikipedia page). But a casual implementation ended up not working at all, prompting me to look for an existing implementation to learn from. However, most implementations I found looked hideously complicated (or just hideous), not necessarily correct, and/or used out-of-date programming languages and styles. It therefore seemed like a good idea to create a clean, simple “reference” implementation of this algorithm, using a contemporary and widely known programming language and style.

## 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.

## On Web Design

When doing research to get this website up and running, I came across the following two truly inspiring examples:

## "That's funny..."

The most exciting phrase to hear in science, the one that heralds new discoveries, is not “Eureka!” (I found it!) but “That’s funny…”.

## 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).

## A Hugo Survival Guide

Hugo is a static site generator: it takes some plain-text content, marries it to a bunch of HTML templates, and produces a set of complete, static HTML pages that can be served by any generic, stand-alone web server. Simple.

## Announcement: Hugo Survival Guide

I have compiled my various write-ups on the Hugo site generator into a single, consecutive guide.
