AccessibilityMapper is a native macOS and Windows application for advocates, planners, and community organizers who need to quickly visualize non-car mobility coverage on a map.

Drop a marker on any location and four concentric bullseye rings appear instantly — a red 0.5-mile walking zone, a teal 1.0-mile Safe Routes to School ring, an orange 2.0-mile cycling zone, and a blue 3.0-mile low-speed vehicle corridor covering e-bikes, scooters, and similar modes. Multiple markers can be placed, named, and toggled independently, giving audiences an immediate picture of where people can move without a car.

Additional tools include on-demand city, county, and state boundary overlays, three map styles (standard, satellite, hybrid), and individual layer toggles for each ring type. Maps are saved as portable .accmap files that preserve all markers, boundaries, and viewport settings.

AccessibilityMapper is available on the Mac App Store and as a direct download from druware.com. The source code is open under the GNU General Public License v3; compiled binaries are covered by a commercial license. Free for personal use — if it saves you time, consider supporting it through the a donation on the Druware website.

Bike Law Pocket Guide is your on-the-road companion for understanding bicycle laws across the United States. Whether you are commuting through your own city or riding somewhere unfamiliar, the app gives you quick access to the laws that protect cyclists — from helmet requirements and right-of-way rules to infrastructure standards and the legal protections that vary state by state.

DMARC reports,

finally readable.

Every mail receiver on the internet sends you aggregate reports as dense, machine-shaped XML. Open one in DMARC Report Reader and you get the answer instead: what passed, what didn't, and which sender is the problem.

A .net library for quickly and easily adding a command line options interface, complete with help file display and easy parsing. This is available as a NuGet download, as well in full source form from it's Github repository.

A .net library collection of extensions that the Druware Libraries make use of. These extensions revolve around convenience methods for string and byte array handling but may grow and expand well past that. For the most part, they are just short cuts, and in some cases, there are other vectors to solve the same problems using existing libraries.

Druware.Server is a foundation. A building block of sorts from which a bunch of other little libraries build from, which when combined help us build entire systems with a very high level of reuse. Rather than create a separate project for each of those libraries, we are referencing all of them from here, though most are in different, related Github Repositories.

A quick reimplementation of the venerable Windows SDK GUUID tool that provides a simple and consistent graphical interface for generating GUUID's. Originally written in Objective-C, this version is fully implemented using Swift and SwiftUI.

The ODBCKit is an open source framework for Cocoa developers to leverage the underlying Open Database Connectivity resources in the business network.

The PGSQLKit is an open source framework for Cocoa developers to leverage the power of PostgreSQL in their applications. Built with the intent of providing an easy and approachable toolkit for Cocoa Developers, it has evolved into a little bit more.

Not quite ready for publication, the Pool Manager ( for Pools and Spas ) is a document based tracker for your pool water chemistry and treatments to help you predict it’s needs and track historical treatments.

So much of building a RESTful client is boilerplate code work. The kind of boilerplate that is prone to creating problems later if something is not fully implemented. This is the result of our desire to not recreate the wheel every time we need to do a RESTful interface. Since we work in both C# and Swift, we wanted something that was very similar. This is the Swift implementation of our RESTful base.

These days, the QR Code has become one of the most ubiquitous ways of sharing url's. While there are a lot of free online tools to create them, most use some form of url redirection in their implementation. This is simply a quick command line tool that automates the process without any external dependencies or trackers.
