Ran this through Google’s Big Query on the two largest political subreddits on reddit.com. The two queries were
SELECT domain,count(*) as Count FROM [fh-bigquery:reddit_posts.2017_01] WHERE subreddit = "politics" GROUP BY domain ORDER BY Count DESC
SELECT domain,count(*) as Count FROM [fh-bigquery:reddit_posts.2017_01] WHERE subreddit = "The_Donald" GROUP BY domain ORDER BY Count DESC
Make your own conclusions, but the results are pretty telling for the diversity of posts and their content.
This is the data which resulted from scraping the top 1,000 “hot” posts from various subreddits. As you can see, the_donald posts originate heavily from new accounts. You could explain the discrepancy as “political season”, but SandersForPresident doesn’t seem to have that issue. Reddit was predominately left beforehand, but then you have to wonder why people are starting to gravitate toward reddit for their pro-trump discussions.
Seems like something is up. An explanation given by a pro-trump person was “conservatives get banned”, but they sure don’t get banned from the_donald, and it is against policy to create new accounts to access subreddits you have been banned from. Heck, when the_donald banned me they explicitly stated that. Anyhow, enjoy.
Whipped this up based on the 2011-2013 ODOT data because someone was complaining about cyclists not paying the gas tax where they lived (Portland). Whelp, taking into account the damage (1/9,600 the damage of a car, and roads cost a pretty penny to repair) and that many cyclists have cars if not at least a license, (89%) it is clear that cyclists subsidize motorists. Oh yeah, pollution. It is 2016, can we stop hating cyclists?
While looking for city data to keep up with my data analysis and visualization skills I found a disturbing data set.
The Minneapolis Police Department uses automatic license plate recognition to help aid in solving crimes in real-time. They also maintain this data about innocent citizens for months after it was collected. These data were obtained legally, via the Minnesota Government Data Practices Act. They have been pre-processed and deidentified. This file contains over 800k plate readings. – github.com/johnschrom/Minneapolis-ALPR-Data
I decided to check it out, and see what a limited exploratory analysis could determine from the top 20 license plate hits, I will start with the biggest issue (in my opinion),
Determine When a Person is Home
Here is a map of the top 20 license plates and the data points for when the police scanner ran their plate.
Now if we look at a time where people are most likely at work (say 11am) we can grab the hashes of the license plates that work at specific locations.
You can see above that the purple person is almost always SE of the cities, The lat/long is 44.935696,-93.38466 which corresponds to the Home Choice Parking lot in Hopkins, MN. Where will they be 12 hours from then?
Above you can see they pretty much always return to Dinkytown, Minneapolis. Using this method you could potentially
Determine whether or not a person is likely to be home at a certain time
Determine where someone likely lives
Determine where someone likely works
Determine if your employee took their car out when they called in sick (two data points already known)
Determine what someone is up to on their time off (if work and home locations known)
Obviously with more data points the more reliable the data becomes, and this was only run for a few months with much of the data tagged with a 0/0 for longitude and latitude.
Using Police Data to Track Targeted Neighborhoods
Using the same data it is also possible to track which neighborhoods are targeted by these scans
