Examining 12 Months of SEPTA API Queries

With the release of SEPTA’s new app, I’ve suddenly been flooded with questions about their API. People wanted to know how stable it was.

Well, I don’t work for SEPTA, which means I don’t have insight into their operations, but I can perform some analytics based on what I have, which is approximately 18 months of Regional Rail train data, read every minute by SEPTA Stats.

Overall Stats

This is all of the data that I have in Septa Stats currently:

  • Events Since Inception: 26,924,887 events
  • First Event: Mar 1, 2016 12:00:01 AM
  • Last Event: Nov 16, 2017 10:33:53 PM

That’s way more events than minutes in that timeframe, and the reason for that is each API query is split into a separate event for each train. So if an API call returns status for 20 trains, that gets split into 20 different events. This is done because Splunk has a much easier time working with JSON that isn’t a giant array. 🙂

I’m proud to say that there is now a dashboard for the entire Regional Rail system. It is present on both the front page and the “SEPTA System Stats” page:

This new dashboard makes it straightforward to determine the status of the entire Regional Rail system at a glance.

Running Dorsai Thing 2013: Lessons Learned

The Liberty Bell

Each year, The Dorsai Irregulars have their own annual convention known as “Dorsai Thing”. It is a weekend long event, held in a different city each year, where we all gather, socialize, and hold our semi-annual business meeting. This year, it was held in Phildelphia, and it fell on my shoulders to run the event, dubbed “Liberty Thing” While I’ve worked at plenty of conventions before, this was the first one where I was effectively the Con Chair. This was an entirely new thing for me, and I wanted to write a blog post about some of the things I learned during the experience.
