Changelog Structure

I recently changed my preferred structure for changelog files. Examples of the old structure are shown in the Qprompt changelog while the new structure is shown in the PopPage changelog.

The new structure is based on suggestions from Keep A Changelog. Liking the clarity and brevity of this style, I updated the changelog section in the Unified Style Guide to incorporate their suggestions.

While I don't plan to update old changelogs, new changelogs will definitely …

PopPage Demo

PopPage is a small side project I started a few years but haven't really updated much until recently. PopPage was originally a simple static HTML generator; at the time I just needed a utility to apply content to Jinja2 templates. However, recent updates have effectively made it a cookiecutter clone with a few neat features. Unlike cookiecutter, PopPage information is supplied from YAML files rather than JSON files. As of PopPage 0.3.1, there …

DevLog - Qprompt

Qprompt is a simple CLI library for Python that I have slowly working on for about two years now. It provides basic typed prompts and menus in a CLI environment along with some additional convenience functions. Recently, I added a feature that allows prompt inputs to be automatically entered via stdin; I have found this feature to be enormously helpful. Let's look at an example use case.

Use Case - QuickWin Build Menu

The Q&A

What is a Kalman Filter (KF)?

Better Task Lists In AsciiDoc

NOTE: This is an update to a previous post.

Okay, it's been a while since the last post on this topic. Since then, I've switched from using the original AsciiDoc utility to Asciidoctor. This along with some minor tweaking has changed how my task lists look.

Here is the basic structure:

Question Drilldown - Processes, Threads

This is the first post using a format that I have been wanting to try out for a long time. The idea is to catalog the questions that might be asked when first learning about a topic. By reviewing these questions, hopefully newcomers can learn a great deal and the more experienced can brush up a bit. The goal is not to exhaustively review every detail on the topic but rather provide just enough information …
