Expert Areas

Given below are some areas that have overlaps with internal projects that you'll be working in CS3282. Picking these will have the advantage that your work in the internal projects can increase your expertise in the chosen areas (i.e. your work in CS3282 can help you earn more credit in CS3281).

Languages

Here are the main languages used in the three projects (PL : PowerPointLabs, SE : SE-EDU, TM : TEAMMATES).

Language Projects
Java SE, TM
HTML TM
CSS TM
JavaScript TM
C# PL

Tools, Tech Topics

The aspects, tools, topics given below can help you to pick an aspect and a topic to study.

Code Quality

  • Static analysis
    • Checkstyle TM SE
    • Codacy SE
    • ESLint TM
    • FindBugs TM SE
    • PMD TM SE
    • Stylelint TM
    • StyleCop PL

Dev Ops

  • Build

    • Gradle TM SE
    • MSBuild PL
    • npm TM

  • CI

Desktop

  • GUI

    • JavaFx, ControlsFx SE
    • Windows Presentation Foundation (WPF), Winform PL

  • Installers SE PL

  • Portability SE (ensuring the apps can run an all major OS'es)

Documentation

Generating and maintaining user/developer docs require good writing skills as well and various tools.

  • UML TM SE PL
  • Document generation TM SE PL
    • Jekyll PL

Fault Tolerance

This is especially important to TM because Web apps are vulnerable to all sorts of intermittent faults. For example, one problem it faces is called 'eventual consistency' where new data requires some time to propagate through all nodes of the distributed database during which time the app has to deal with data in an inconsistent state.

  • Logging TM SE PL
  • Error reporting TM SE PL
  • Backup and restore TM

Performance and scalability

This affects all three projects:

  • PL : Users don't like their PowerPoint to slow down due to our plugin
  • SE : We want the app to be very fast and to be able to handle lot of data (especially when connected to third party backends such as Google calendar)
  • TM : 1. It has to deal with spikes in load. 2. Every CPU cycle or byte of data transfer costs us money.

Sub areas:

  • Multi-threading TM SE
  • Profiling TM SE PL : To find performance bottlenecks
  • Scalability testing TM SE

Security

  • Vulnerabilities TM: SQL injection, cross site scripting
  • Access control TM
