Geocentral Location; Addresses to Coordinates
Recently, I needed to plot numerous addresses on a map and, ultimately, find the geocentral location of all addresses. The geocentral location is the weighted center of all the addresses, which can be useful in helping determine numerous things, including the average distance between all addresses and some other location. The geocentral location is attained …

A Correction for the WSJ: So, Who Did Invent the Internet?
Recently, Gordon Crovitz wrote an opinion piece for the Wall Street Journal titled Who Really Invented the Internet? Fortunately, it’s only an opinion piece, because there was little more than opinion, littered with plenty of misinformation, in the writing. You can read the article here.

The Napster Revolution
I’ve recently been reading through Steve Jobs’ biography, a phenomenal work by Walter Isaacson. A point that Isaacson keeps coming back to throughout the book is that Steve Jobs revolutionized six different industries: animated movies (through Pixar), personal computing, tablet computing, phones, digital publishing, and music. I don’t disagree with Isaacson. Jobs did revolutionize the …

Reagan.com Email is a Misguided Effort
I heard a commercial with the booming and illustrious voice of Rush Limbaugh. After I recovered from banging my head against my desk, I reflected on what was said in the commercial. Rush pointed to the popular free email providers (Yahoo, Google, and others) to remind you that they scan your email. To remind you …

Secure PHP Login
When perusing the internet for discussions on PHP sessions and cookies in regards to credential validation and user logins, I’ve never been satisfied with the approaches I find.

SOPA Highlights
The Stop Online Piracy Act (SOPA) and the Protect Intellectual Property Act (PIPA) are two bills currently mingling in the United States House of Representatives. It would take too much time and effort for me to explain how ludicrous it is that we have misinformed politicians writing litigation for an internet that they apparently do …
