In my spare time

For many people, they do one thing at work and have a hobby or three at home that they pursue. For me, programming is both my work and my hobby.

I have always loved programming, and when I firsted created my website ~9 years ago I created a small list of the projects I was working on. Since then, I have always tried to have at least one or two projects going on; they are cataloged below.

Lost & Found Winter 2015

A PHP application to allow for conventions to have their own lost and found kiosk

you can read more about it here

Shared Voice Fall 2014

A twitter app similar to but a more homebrew approach

You can read more about it on my tech blog

Arc Star Fall 2014

A simple archiving extension for chrome and chromium

You can get it here

Temporary Chat Fall 2014

An anonymous chat room created in C and Javascript, created as a set of tutorials to provide examples of CGI with C

You can view the server here and start the tutorials here

PCI, Private Chat Interface Summer 2014

An exercise in creating a chat interface using C CGI and Javascript. Static site with Harp and CGI backend similar to BGI.

You can see the blog post about it here

BGI, Budget Gateway Interface Summer 2014

A simple application to keep track of spending habits and display metrics. Created as a static site using HarpJs that uses a C CGI backend with a custom flatfile datastore.

You can checkout the repository here.

WordPress2Harp Winter 2013

Created a small python script to migrate a WordPress site to a Harp one after lurking in the Harp IRC's.

You can see the WpJson4Harp script here or see it featured in a blog post from Harp here!

GreenServ Winter 2013 - Spring 2014

GreenServ is a custom JSON only, API server written in C to provide a backend to the Green Up VT project. Created to replace the python Google App Engine version of the API, it was coded to spec (with some minor enhancements) and under stress testing performing much better than the instances of the App Engine

You can view the GreenServ repository here

TimeCatcher Fall 2013

TimeCatcher is a time logging utility which doesn't eat your CPU cycles. Most logging software runs in the background spinning the clock away to keep track of your progress. TimeCatcher works on a simple start and stop system managed through the command line in order to not do that. Memory leak free and supporting command completion through bash shells, time catcher is a simple to use and good time logging program.

Xemark Summer 2013

Xemark is a simple markdown language designed to be translated into html by a parser following it's BNF grammar. The parser was used as a component in generating this webpage. A bash script made did the rest of the work. Xemark functions like a CGI script in that it's input is translated from one format to an output in another (in this case xemark markdown to html). Becuase of this property it is easy to use xemark within a http server context to serve .xe files up as html to users.

You can see the repository for xemark here

Green Up VT Summer 2013

An application to assist with GreenUp Vermont and help to coordinate volunteers. Developed as part of the national Civic day of hacking challenge by Code for BTV. The application was hastily made in php during the event. Then heaviy refactored into a RESTful API with mobile,ios and android client interfaces (Still in progress). My main contribution was the specification, design, and implementation of the REST api backend done in python. Also primarily responsible for task delegation and repository contribution maintenance.

Danger Zone Fall 2012

A class-wide software engineering project for CS 276 at UVM. Using twitter data to find regions of high danger in the world and display them to users so that they can avoid them. My role was on the Server/Machine Learning team, creating a classifier for tweets. As well as constructing a command interface between php and java to link the Zend Server pages to the Java Classifier.

WayPoint Fall 2012

An android application designed for runners. Users set down markers on a map and then when they reach it, it takes down the time. When the final marker is reached, the total times are displayed.

See the Waypoint github repository here

Green Bean Fall 2012

A team app created for the Hack VT competition in Winooski, VT. The app listed ingredients using a recipe API and then our app displayed farms where those ingredients could be found. Weather data for the last year was integrated into the colouring of the markers of the farm to show how much precipitation had fallen, to render a crude quality estimate of the crops. Once ingredients were selected, a user could select dishes to get recipes using the ingredients they had selected

Approaches to Solving Infinite Q-Learning Oscillations in a Grid World Spring 2012

My term project for CS295 Machine Learning, using Matlab I implemented Watson's Q-Learning Algorithm and applied it to a simulated Grid World. Upon discovering an issue involving circular logic as a result of the algorithm, I implemented 4 new approaches which resulted in a drastic improvement in performance in trail simulations. The next year, the professor asked to use my paper/project as an example of what his students should strive for.
