DrawUI – Fast and Versatile Inking for iOS: I’m very interested in low-latency drawing/inking on iOS, and DrawUI is drop in library to support high performance ink. The framework cleanly separates the touch input from the pen-stroke model from the ink rendering itself. This clean separation allows for principled optimizations and customization.

Prison Entrepreneurship Program (since 2017): I volunteer my time with this phenomenal program that helps inmates learn how to start their own business when they’re released from prison. The results are amazing – Baylor University did a study and found a dramatic reduction in recidivism and an increase in employment from this program. Learn more and volunteer at

AskMeEvery (since 2014): AskMeEvery will automatically email you any question you setup for simple and personal daily accountability. It’s extremely easy and effective way to encourage new habits and break bad ones.

Books for Robots: We humans are very analog creatures, but we surround ourselves with digital tools. I wonder what the robot equivalent of that is? If we’re analog creatures using digital tools to consume analog information, then robots could be digital creatures using an analog tools to consume digital information. First in the series. Second in the series.

Open Source: Much of the code from these projects is available on my GitHub profile, including Loose Leaf iPad note app, PerformanceBezier, which dramatically speeds up common bezier operations in iOS, and ClippingBezier, which allows for complex operations on UIBezierPaths.


Funnel Analytics (2019): Marketing automation and business intelligence web app that combines data from all of your data sources – GA, Mixpanel, a spreadsheet, etc – and let’s you combine that data into a single datastream, and then get realtime updates as it changes and even automate your systems from these data streams.

Building with Neurons (2017): Writing a book explaining how neural networks work at their most basic level, including all of the math and code to derive the simplest neural network possible.

Loose Leaf (2012-2015): As its name implies, Loose Leaf mimics a stack of loose leaf paper; it’s a place to be messy and creative on the iPad. Its unique scissors and ruler tools give you surprisingly flexibility with its intuitive gestures. All of the code is open source and available on Github, the Loose Leaf blog, and website.

  • PerformanceBezier: Drop in optimizations to dramatically speed up UIBezierPath.
  • ClippingBezier: Find intersecting points, paths, and shapes between two UIBezierPaths.
  • JotUI: OpenGL inking view for iOS.

Remotely (2016): The successor to Here, File File!, Remotely lets you easily and securely access the files on your Mac or other devices. Focused on ease of use, it’s simple setup doesn’t require syncing your files to someone else’s datacenter –  you stay in control of your data.

Spare Parts (2015): Spare Parts is an open source 2D physics game that was developed 100% on live stream over the course of two weeks. Every line of code was written on stream, and the full source code is available.

PageCollectionView: A modernized Loose Leaf layout for an arbitrary number of documents with arbitrary number and shape of pages. Provides a UICollectionView, controller, and associated layouts to transition smoothly between documents, grid, and page views. Performance and layout flexibility are prioritized. (2012-2014): Jotbook is a simple way to create and collaborate on bulleted lists in your browser. Easily edit and share lists together.

Columnizer JQuery Plugin (2010-2014): Layout your content into columns on the fly and adjust to different screen widths with this auto-columning plugin. Sample PageSecond Sample. Third Sample.

Here, File File (offline, 2009): Here, File File! was an iPhone and Mac application to let you browse, view, download, and share your Mac’s files from anywhere. In early 2010, Here, File File! was featured in an Apple Commercial. (offline, 2005-2008): Jotlet Online Calendar was the first native-feeling web calendar application, launching a few months before Google Calendar, and the first application to offer a full JavaScript API for rich client side integration. On April 1st, 2008, Jotlet was acquired by Jive Software.

Aurora Calendar (2003-2004): Aurora Calendar was the precursor to Jotlet. Built by myself and Buck Wilson when we were in college, it pre-dated Google Calendar by a few years, boasted calendar sharing, custom fields, task delegation, and more. The original site is archived here, and a demo instance is archived here, and the source code is available on Github.
