Real-Time Thermometer with SmartThings and PHP

Here is a real-time FirstMark temperature monitor, created with a SmartThings starter kit, Highcharts.js, a little bit of PHP, and MySQL. (Doesn’t look great on mobile yet.)


Now we’ll always know whether it’s LDL or RH temperature! This is how crazy simple the SmartThings SmartApp code is:



The Most Popular Classic Rock Songs

Using the yes.com API, I was able to load playlists for over 1,000 different radio stations. There is a lot of data to analyze here, but one of the first questions I sought to answer was “What are the most popular songs and artists on classic rock radio?”

Originally, I categorized any station that played Aerosmith and Led Zeppelin at least once per day as a classic rock station. An astute friend pointed out that I was “sampling on the dependent variable.” To address this, I filtered for stations that played (i) at least one song by Pink Floyd, Led Zeppelin, The Beatles, Fleetwood Mac, the Rolling Stones, and Aerosmith, and (ii) played at least one song by all of those artists. The source data do not have reliable genre tags, so this is the most appropriate test I could think of; I am open to alternative suggestions.

Of the 1,000 radio stations, 91 are considered ‘classic rock.’ Across 1 week, 111,000 songs, 5,421 unique songs, and 1,448 unique artists, here are the twenty most popular songs:
