I’ve taken sketchnotes at numerous events, including Clojure/conj and Agile Conf. Sketchnotes are a great way of using doodles as a memory aid and visual trigger of a talk, as well as help capture high-level ideas and conceptual relationships. I’ve written more about sketchnoting and tips on getting started on Atomic Object’s blog.
Islands is an island map generator. Its remarkably simple algorithm generates complex island shapes, complete with bays, river inlets, lagoons, chains of islands, and rocky shoals. It’s a perfect blank slate for creating imaginary island civilizations.
Stack Math is a tool for creating and verifying mental math algorithms. Inspired by stack-based programming languages like Forth, it helps in re-designing useful math formulas so they’re easy to calculate mentally rather than with pen and paper.
Atomic Spin is Atomic Object’s technology and business blog. I’ve contributed to it since 2012. My work ranges from specifics like scripting Tmux and how to sketchnote all the way to high-level, abstract ideas like story, notation, and agility.
Solar System is a map of the major bodies in our solar system on any given date. It can also show the distance between any two selected bodies.
Burn Chart is a simple burn-up chart generator. It plots the total project scope and progress so far. It also estimates when the project is likely to be complete. Charts can be downloaded as PNGs.
Suarez Quilt generates intricate, random grids evocative of quilts. This browser-based generator also allows coloring sections.
Pennygame is a simulation of a simple manufacturing line. Based on an exercise in the book Velocity, Pennygame illustrates how higher productivity can increase work in progress—and therefore costs—and how constraints can reduce WIP and free up resources even while maintaining the improved throughput.
Having used the Elm architecture to build several simple, in-browser apps, I presented Implementing the Elm Architecture in ClojureScript as a lightning talk at Clojure/conj 2015. The presentation describes the Elm architecture, the virtual-dom project, and how to use core.async channels to drive an application’s state and rendering.
Having used the Go programming language and developed an appreciation for communicating sequential processes, I presented Communicating Sequential Processes at SoftwareGR in September 2015. The presentation discusses problems caused by sharing memory and shows how CSP is a better way to model concurrent logic.
Conflict Resolution Diagrammer is a web app for resolving conflicts. Users can outline a problem and the reasons behind it, including the underlying assumptions, in the process revealing the erroneous assumptions without which the conflict disappears.
Streak Calendar is a annual calendar for tracking daily practice. It’s useful for developing regular, skill-building habits, such as writing, drawing, exercising, playing the piano, or anything else. It’s small and simple, perfect for chaining 365 days of X’s.
Small, Fast, & Simple is a series of 29 micro essays on how to program smaller, faster, and simpler. It ranges from old ideas like functions to new tools like D3 and Hugo. Each entry is less than 100 words, leaving further investigation to the reader.
Having learned about sketchnoting at Midwest UX in 2013 and practiced through 2014, I presented Sketchnotes: Harnessing the Messy Mind at the first ever Atomic Con. In it, I argued for the superiority of visual notetaking and shared tips and tricks. The presentation features sketchnotes I took at AgileConf 2014.
V is an experimental K-like programming language intended for data visualization.
Flinch is a stack-based programming language useful for modeling and improving mental math algorithms.
Elevations is a web app for reading GPS XML files and showing not only where individual trips took place but also their change in elevation. I originially wrote it in 2013, the year my wife and I finally met our goal of biking 1,000 miles in a single summer.
Rail Baron Payoffs is a web-based map of cities in the board game Rail Baron. It’s used to look up the cash payoff of hauling goods between two cities, and replaces the 67×67 table of payoffs that comes with the original game.
D3-raylabel is a D3.js plugin for creating angled labels on pie and ring graphs. Supports placing labels inside the ring, on the ring, or outside the ring, as well as several other configuration options.
Like is a suite of command-line tools for working with similar text. Included are commands to find the entry in a list that best matches the given text, finding files whose names are most similar to the given text, and sorting text by similarity.
