Tale of Two Cities: Faith and Progress
Around 1710, the English theologian Thomas Woolston wrote that Christianity would be extinct by the year 1900. In 1822, Thomas Jefferson predicted there is not a young man now living in the United States who will not die a Unitarian. While these predictions didn’t pan out, we live in a world that neither of them…

Review: Leadership by Doris Kerns Goodwin
I love how Doris Kearns Goodwin and Laura Hillenbrand explore American history through clear and clean prose that emphasizes strength forged by adversity. I started with “Team of Rivals”, but “Leadership: In Turbulent Times” is emerging as my favorite from Goodwin.

New Jersey School Heat Map
This morning before church, I wrote some code to build a contour plot of schools in New Jersey. The “hot” reddish regions have the best schools and the cooler regions don’t. Tech Stuff: How it’s made This wasn’t that easy. Since I had all the code from my previous post, it should have been very…

Coding for a New House
I don’t want to read about it, just take me to your super cool interactive map. We are moving to the greater New York City area this summer where Tim joins the leadership team of Colgate-Palmolive. As tempting as it is to spend all our time on Trulia, Estately or Zillow looking at specific houses,…

Common Mathmatical Libraries: Computation, History, and Trust
A common complaint among engineers is that modern computers obscure the details of the complicated math they produce. We cringe when children are exalted as “knowing computers” from a young age. Bill Gosper and Richard Greenblatt had perhaps the maximum benefit to “learn computers”. They didn’t have wolfram alpha or even spreadsheets, they had to…

Tax time automation
Happy New Year! Bring in the new year with some code to transform USAA bank statements into a set of transactions for 2016. It is a little tricky because there are some 2015 transactions in the list and USAA puts transactions on two lines. To use, just save the bank statement pdf as text and…
