TrialPay Offer Similarity

I just published my first post to the TrialPay Enginerds Blog.  The post details some work I’ve done to categorize offers from TrialPay’s advertisement network as “similar,” and identify “communities” of offers.  There’s also a neat visualization of an adjacency matrix, which I built using d3.js.  The visualization is an adaptation of some work done by Mike Bostock.

Honey Badger Softball Stats I

TrialPay’s softball team, the Honey Badgers, began our season last Wednesday.  In addition to playing, I’ve decided to make myself the team statistician.  Drawing some inspiration from the JHU physics graduate student intramural softball team, I thought it would be fun to keep a running tabulation of players’ lifetime statistics.  In order to keep it manageable and given that I’m also playing, I’ve limited myself to basic offensive and pitching statistics. 

The box score from our first game can be found below the jump.

Come Work at TrialPay!

This past Wednesday to Friday, we had our quarterly hackathon at TrialPay.  The hackathon gives engineers and other interested parties a chance to work on some fun projects that aren’t what is normally considered high urgency (e.g., data visualization or in-office announcements) in a short amount of time. 

The hackathon this quarter was hiring theme (i.e., projects that would be useful when trying to recruit new hires).  I used the hackathon as an excuse to write a hiring tune for TrialPay, “Come Work at TrialPay!”  In the future, it would be really fun to make a higher quality recording of the song, and film an accompanying video.  In the meantime, here’s a rough (both in terms of equipment and performance quality) recording 1.
