About The Project

This project is part of the course DevOps, Software Evolution and Software Maintenance, MSc (Spring 2024)

The project currently consists of two folders:

• itu-minitwit, which is a small Twitter copy made in Python.
• csharp-minitwit, which is a ported version of itu-minitwit, made in C#.

Built With

• .Net 8
• ASP.NET
• SQLite

Prerequisites

• A modern Python, i.e., version >= 3.10,

  • There are various ways of installing it, either via the system's package manager (apt search python3)
  • manually from python.org
  • via pyenv
  • via Anaconda

• The Python dependencies from itu-minitwit:

  • Flask >= version 3.0.0
  • Werkzeug >= version 3.0.0
  • Jinja2 >= version 3.0.0

• A current C compiler, e.g., gcc

  • Likely it is already part of your Linux installation.
  • You can check that, for example with:

  gcc --version

  • Since the flag_tool is a C program, you have to compile it again:
    • flag_tool includes sqlite3.h, which is likely not yet installed on your system.
    • It can be installed (together with the required shared library) via:

    sudo apt install libsqlite3-dev

• To work with the database, you likely need sqlite3 ((apt search sqlite3))

  • To inspect the database file while refactoring, you might want to use a tool to "look into" your database file, such as the DB Browser for SQLite, which you can install via:

  sudo apt install sqlitebrowser

• The .NET 8.0 SDK. There are multiple options for downloading depending on your operating system. If on linux, we recommend the scripted install.
