OSU students (well, college students in general) enjoy being safe. Whenever a crime occurs on campus that has a continuing safety threat, OSU sends every student and staff an email briefly explaining the crime. However, OSU doesn't send crime alerts for all crimes that occur on and around campus (where many students live). The reality is that we live in a dangerous world, and we want to be aware of what is happening around us.
AwareOSU visits the Columbus Police Department's unofficial web report portal (to find off-campus crimes committed in zone 4, more on zone 4 later) and the OSU Police department's daily log system, finds information related to crimes committed in the university area the previous day, and sends this information out to users.
For users who select the daily delivery option, AwareOSU will send an email each morning at 10:15 AM containing crime information from the previous day. For users who select the weekly delivery option, AwareOSU will send an email containing crime information from the previous week at 10:20 AM every Saturday morning.
AwareOSU also performs analytics. On the first day of every month, AwareOSU will send out a detailed report to users containing breakdowns of crime occurrances, locations, and monthly trends.
Great overview. What is the code actually doing?
Main - This Ruby script runs daily at 10:15 AM. It utilizes three great gems (Mechanize, Nokogiri, and Mail) to visit the CPD web portal and OSU PD online log system (listed above) using Mechanize, parses the HTML of the search page containing all crimes committed yesterday using Nokogiri, and sends the information out in a HTML table using Mail.
Weekly - This Ruby script runs every morning at 10:20 AM. It utilizes three great gems (Mechanize, Nokogiri, and Mail) to visit the CPD web portal and OSU PD online log system (listed above) using Mechanize, parse the HTML of the search page containing all crimes committed yesterday using Nokogiri, and write this information to texts files everday. On every Saturday morning, This script will gather all crime information for the week and email the information out in a HTML table using Mail.
Analytics - This Ruby script runs on the first day of every month at 10:00 AM. It utilizes two great gems (Mail and Gchart) to analyze crime information from the previous month, inserts data into charts using Gchart, and sends the information out using Mail. Analytics also attaches two CSV files containing all the crime information AwareOSU analyzes for the entire month, in case users want to perform their own analysis.
Please note: AwareOSU is run on a Raspberry Pi.

Off-campus crime information is pulled from parts of Zone 4 (Districts 30, 33, 34, 40, 41, 42, 43, 44, 50, and 53), visualized here
Why are some crimes listed multiple times?
This is because some crimes may have multiple victims, as seen on the Columbus Police Department's web portal:
Currently, victim names aren't included in the digest. Even though this is publically accessible information, I'm not sure how comfortable people would feel with names being emailed to AwareOSU users.

10/24/2015 - AwareOSU is now running from a Raspberry Pi! What does this mean? Basically, this means that AwareOSU is just about fully automated. The only thing I do now is add emails to the Google Group of people who have subscribed, and the Pi uses a CRON job to run Aware OSU every morning at 10:15.
10/22/2015 - Program now searches and retrieves on-campus crimes, in addition to off-campus crimes.
10/17/2015 - AwareOSU has 100 users.
10/17/2015 - Apparently Google only lets users send out a max of 100 emails/day, so the firstname.lastname@example.org account got suspended for a day. From now on, I will be using a Google Group to mass email everyone who signed up through the Google Form. For future software engineers: this is why we test every aspect of our code.
10/16/2015 - AwareOSU is released.
Crimes listed on CPD's web portal is not representative of all crimes that have occurred.
