Capabilities

• Hosting contests, with live-updating scoreboards
• Intuitive problem-setting interface
• Grader support for Python, Java and C++
• Persistent Scoreboards across system restarts
• Client-side storage of problem results
• User accounts
• Interactive grading
• Reworked UI
• Teams in practice contests
• AWS integration (lambda + dynamodb)

KNOWN BUGS

• Past problem results may appear on the client side for 2 players on 1 browser account (or otherwise with shared localstorage)

Dependencies

Requires python markdown and flask libraries, as well as g++, java, python2.7 and python3.9.

Usage

• Use a WSGI of your choosing to host the website in main.py
• Run grader.py on the same machine
  • You can run multiple graders, but they have a decently high chance of racing for any given submission so it's highly discouraged
