Introduction I have been struggling with geocoding for about a year now, and have begun to learn far more than I wanted about the ugly details of the tools available for free. In particular I have been using Google and the US Census Bureau for geocoding. They each have their own strengths and weaknesses, so I thought it would be appropriate to share what I have learned. I would call Google promiscuous - they will try very hard to return a location to you, even if it is all wrong.

Personal weather station conversion I have been running wview since June 23, 2012. It has been a reliable workhorse, but it doesn’t appear to be maintained any longer, and it does have a couple of issues. The new, improved open-source product seems to be weewx, so I’m migrating to that one. This is the story of that conversion. Preliminaries I know that my old database has some bad data in it, so the first thing I want to do is figure out where that bad data is, and fix it before I migrate the database.
Houston Crime Statistics A debate began on my neighborhood list. “Crime is increasing in the Heights!”, “Crime is not going up in the Heights!” and so on, back and forth. Then someone noted that all the crime data is on the Houston Police Department website, so someone could just download the data and answer the question. I thought to myself, “I could be that someone”, so I started working on it.
