Daily: A personal journal and performance tracking web application

Project Description

The sole purpose of this application for now is to track my daily activities, and the ratings I give to either those activities, or the days themselves as a whole. These ratings coupled with daily events will generate patterns that allow me to find events that have a negative impact on my daily well being (i.e. events that consistently lead to a negative score).

The project also coincides with my intereset in data and extracting patterns that can be used to support optimization and long term oriented planning. Visualizing data sets is a large component of this and I am keen on adding that in as well.

Project Status

A minimal web interface is up and running at www.dailydata.me using pythonanywhere. A demo account is available with username: demo, password: demo

Installation and Setup Instructions

Clone this repository with git clone git@github.com:EternalGoldenBraid/daily.git.

Initialize a virtual environment within daily/ to prevent your main system's python packages from interfering: python -m venv env.

Activate the virtual environment with source /daily/env/bin/activate.

Install required python packages with from daily/requirements.txt with pip install -r requirements.txt.

Set the environmental FLASK_APP variable with export FLASK_APP=daily.

Run the application with flask run and test using the provided URL.

Task List

Visualization

• Add data visualization
  • Asychronous parallel processing of data when big operations: https://docs.python.org/3/library/concurrent.futures.html
  • Plot frequency plots for tags. Minimal working model (MWM) up.
  • Plot eigenvalues for tags. MWM up.

Statistics

• Find eigentags and eigendays. Can I use the covariance matrix of tag distributions across days to compose and eigenday using Principal componen analysis (PCA).
• Create a Bayesian (generative) model to predict sleep_rating and rating given a tag vector.

Backend

• Read and setup from SQLAlchemy, Flask and it's plugins' Documentation

• Create database models

• Deploy to cloud

• Implement a web UI

• Add timestamps for event inputs and edits.

• Add multi-user support

  • Add user_id relationships to association tables.

UI

• Add buttons for graphs. Currently /data works as a path for a single page image.

Others

• Add an about page. This readme?

• Configure Database backups
