Survey Says



This app was started in a group of four as a semester long project. Since then I am the only one still working on it with help from Ana Huff.


This app was started in a team of four as a class project. We used to manage our backlog and taskboard. We would rotate scrum roles through out the semester

Ana Huff - Helped out with the sticky header and polishing of the UI


The UI design was inspired mainly by twitter as well as some other popular apps and websites like Facebook and Amazon.

Code Smells

Most recently I have been working to refactor the front end. To do this I have been using Industrial Logic's reference guide to refactoring. Smells to Refactorings Quick Reference Guide. I am working from top to bottom and am currently at "Duplicated Code".
Frameworks/Libraries: Angular4, Ionic, Bootstrap, GraphJS, Plotly, RXjs


The backend contains tests for the various parts of the api. The backend also contains commands to run all of the tests or just specific test files. Each part of the api has its own test file.


The app contains signup and login functionality however, this is only for testing. If this app were to ever appear on an app store this functionality would be removed. Login through Facebook would be the only way to login. This way the application would not have to store any passwords.
The program keeps track of users through an Oauth authentication type system. When users login or signup a token is generated for them which is then attatched to each of their requests to allow them access to their account.

Data Collection

The main inspiration behind this app is that it can be used to collect really useful data sets. Every time the user answers a question their response is saved to the database. This means you could go through every user and retrieve all of their answers.
Frameworks/Libraries: Django


The app collects the tweets through the Twitter api and writes them to a mysql database. To collect the tweets the program sends search requests to the Twitter api using the keyterm '?'. The program collects things about the tweet like the amount of favorites, retweets, users follower count, users friend count, users favorites count, users statuses count, time the tweet was created, time of the query, and whether the tweet contains a picture or video.


To create the model the program takes the 1000 most common words and creates an occurence matrix for each tweet. Then the other data collected about the tweet is concated to that matrix such as users followers, time tweet has been up, users friend count, users tweet count, users likes, and whether the tweet has had a picture or video. Number of retweets is used as the label. Then a linear regression is done to map all the data about a tweet to the number of retweets. Lastly the the coefficients correponding to the unigrams are saved. This model is then used to rank the text of incoming tweets.


To fill up the app with mock data random sentences are generated. To do this the program saves all of the bigrams found in the collection of tweets. Then random sentences are generated by choosing a random first word and then making random choices in the possible words that could follow ( based off the bigram list ).
