Hey! I build games and websites.
Unlike many game devs, I'm a Linux fan. I build my games using free software, and blog about what I learn along the way.

learn coding from me
I founded a cutting-edge coding academy. If you live in the San Francisco Bay Area, you can learn to code by taking one of my affordable, intensive courses.
use my code
I've written some free software, including tools for game dev in Godot. I hope you find them useful!
Upgrading Mattermost using docker-compose
This is a guide on upgrading and/or migrating Mattermost 5.6 (from 4.x) in a deploy that used docker-compose. It's been a year, and I want to freshen up my Mattermost install, get some of the new features. I also want a bit more elbow-room in my Mattermost... Read »

How to quickly install Mattermost on Digital Ocean
Mattermost is a popular free software Slack alternative. Slack can get really expensive really quickly for organizations of any sufficient size, so you either bare with the extremely limited free plan (which holds your data "hostage"), or you switch over to a free alternative like Mattermost. With this, instead of... Read »
Ardour 5.7 Review - Free software DAW
Over this weekend I jumped back into music production, working on some sounds for my current game project. I decided to switch around my work-flow and learn Ardour. Ardour is a totally free software Digital Audio Workstation (DAW) with a professional feature-set for macOS, Windows, and Linux. It has the... Read »
react-jsc3d: Porting a legacy 3D rendering JavaScript library to a reusable React.js component on NPM
Thinking of porting a legacy JavaScript library to be a re-usable React component? In this post I describe the process I used to release a React version of JSC3D. Rational I needed a simple, fast 3D mesh ray-tracer in a React 16 project, and none of the few available seemed... Read »
Introducing: Whiteboard
I made a cool thing: Whiteboard is slideshow application for teaching programming. It embeds a code editor, terminal, and web browser into a slide-show like interface to eliminate context-switches and dead-space, while enabling more content content to be set-up ahead of time. It's great for guiding code-heavy classroom lectures, tutorials,... Read »
Web Developer to Game Developer: Understanding game dev as a web dev using Godot
Already a front-end (or back-end) web developer, and curious about writing your own video games? Maybe want to try a new hobby in indie game dev for PC or console, or publish some mobile games? I made the transition, and so can you! I hope this 10 minute read will... Read »
Snippet: Implement an ability cooldown (in the Godot game engine)
Perhaps you are working on an action game or action RPG where different abilities need different cooldowns, but here's a tiny snippet that can be a re-usable Cooldown utility to check for when abilities can be re-used. Also useful for "rate-limiting" in general, e.g. adding a maximum rate of... Read »
JavaScript syntax cheat-sheet for total newbies
Earlier this year I realized that there aren't any good cheat-sheets for students new to JavaScript and coding in general to learn the (relatively dense!) syntax of JavaScript. Today I decided to make my own! In the past I've really like printing up cheat-sheets as I learned new technologies. It's... Read »
Snippet: Draining all pending coroutines with Python 3's async features
When writing tasks for asynchronous functions in Python 3 I realized I needed a way to run through all tasks that were queued up with asyncio.ensure_future and similar functions. I wrote an async function to do this. The result is a little hacky, as it needs to catch... Read »
The Right Wayâ„¢ to do global npm install without sudo
I'm writing this post since there were a lot of guides online on how to set up NPM so you can do npm install -g (that is, a global NPM install) on macOS or Linux without superuser privileges, but all those guides recommended a rather strange directory structure, such as... Read »
Bash profile trick: Open last used directory when starting a new terminal emulator
As I was configuring my new system (using dotfiles configuration app I wrote for this purpose: stowage), I was exploring the current options for minimalist terminal emulators, and I realized a common pattern I wanted was for new terminals to pop up in the same working directory that I was... Read »
Porting a legacy browser graphics JS script (JSC3D) to Node.js with node-canvas and VM
In this post I will describe my my process to port JSC3D, an unmaintained 3D library that uses the browser's <canvas> 2D context, to run entirely in node.js. This allows a quite fast, easy-to-use CLI-based 3D model renderer. It looks quite good, without the need for GPU,... Read »
Sawdust
Drag and drop blocks onto the board to rack up points and advance to the next level in this addictive new spin on the classic game of tangrams. Two different modes cater to both casual and hardcore-puzzler game styles: Zen mode allows you to take your time to use the... Read »
Releasing Sawdust: Mini-post-mortem
A couple months ago I wrote about realizing "enough was enough" with my feature-creeped game. Along with working on other projects, I spent some time in the next couple months cutting out features and polishing existing ones, all working under a "late-May" deadline. Now, my new (much smaller) vision for... Read »
The Blocklings
I had a blast with my Ludum Dare 38 Compo entry! It's a short (but complete!) puzzle game with 9 levels, something of a cross between Lemmings and Minecraft. Check it out here: Pretty rough in spots, and programmer art galore, but I'm happy with how it turned out. I'll... Read »
Ludum Dare 38
I'm all ready to start Ludum Dare 38! In case you don't know, it's a game dev competition / game jam to make an entire game in 48 hours. It'll be my first go at it, so I'm super pumped.... Read »
Godot Gestures: Pinch, twist, and drag gesture detection for mobile games
As it turns out, writing gesture detection is not an easy task. I gave it a shot anyway, and wrote a re-usable scene for the awesome free software Godot Game Engine. It all started when I decided to switch the focus of my work-in-progress game Sawdust to "mobile-first". To provide... Read »
My pre-post-mortem of rescuing my scope creeped-out puzzle game
It's been nearly 6 months now that I jumped head-first into game development, I've had a fantastic time so far. During these 6 months, in addition to teaching a program on web development, I've been working primarily two game concepts: One ambitious 3D game that is still top-secret , and another,... Read »
