I am integrating "legacy" code with Django, and have problems when the process executing Django must write to legacy code directories where it lacks write permissions. (The legacy code is a Python backend to a Tkinter GUI, which I'm repurposing to a browser-based UI.) I could: Make the legacy directory writeable to all, but this seem...

Assume a game in which one rolls 20, 8-sided die, for a total number of 8^20 possible outcomes. To calculate the probability of a particular event occurring, we divide the number of ways that event can occur by 8^20. One can calculate the number of ways to get exactly 5 dice of the value 3. (20 choose 5) gives us the number of orders o...
