Projects

Frappé(Link)

A slightly Bacon.js inspired Dart package that aims to make functional reactive programming easier in Dart. Frappé extends the behavior of Dart's streams, and introduces new concepts like properties and watchables.

Stitch(Link)

Stitch is a Dart package that uses transformers to generate CSS sprite sheets.

Mesh(Link)

– Present

Mesh is an open-source persistence framework for Adobe Flex. Its aim is to make the retrieval and persistence of Flex application data as transparent as possible.

Mesh provides APIs for defining the associations between model classes, tracking which objects need to be saved, validating the integrity of model data, and mapping models to backend services. In addition, Mesh is completely agnostic to the backend service used. It can be used with any existing AMF, REST, SOAP service, and hypothetically an AIR application running a SQLite database.

Cayri(Link)

– Present

Cayri is a personal project that displays flight statuses for the VATSIM and IVAO flight simulator networks.

The mapping system is based on the AS2 version of Yahoo Maps. However, marker placement was written from scratch to take full advantage of the performance gains provided in AS3, and then overlaid on top of the Yahoo mapping component. This allowed for thousands of markers to be placed on the screen at any given time.

Techniques were also applied to intelligently determine departure and arrival statuses, time to destination, and do aircraft position predictions. A lot of research went into Mercator map projections, processing user generated flight routes, and mapping them to real world navigation stations using the now defunct DAFIF database.

Patents

Intelligent save operation for online collage editor(Link)

United States US 8326945 B2
Issued December 4, 2012

In a server-based system for creating and editing image-based and or text-based projects, the system having access to a digital medium containing an executable graphics user interface (GUI) accessible by computer browser, a method is provided for triggering automatic page save operations and includes the steps, (a) monitoring editing activity occurring in the project editor viewport, and (b) upon detection of a loss of a page from an editor viewport and or detection of a violation of a safety measure, automatically persisting the current page data to the server.

Method for displaying content within an online collage-based editor using a relative coordinate system(Link)

United States US8726186 B2
Issued May 13, 2014

In a server-based system for creating and editing image and or text-based projects, the system having access to a digital medium containing an executable graphics user interface (GUI) accessible by computer browser, a method is provided for scaling a project page using relative units including the steps (a) establishing a 0 point at the center of the project page, (b) from the center, scaling a number of relative units ending at a negative limit value for width equal to one half of total width value, (c) from the center, scaling a number of relative units ending at a negative limit value for height equal to one half of the total height, (d) from the center, scaling a number of relative units ending at a positive limit value for width equal to one half of total width, and (e) from the center, scaling a number of relative units ending at a positive limit value for height equal to one half of the total height. For all of the steps, each unit represents an equal division of the total value from the negative limit to the positive limit for width and for height.
