• Does the concept of "magic number" change from language to language?

  - by Gerardo Marset

  Take the following code in C/C++, for example: int foo[] = {0, 0, 0, 0}; No magic numbers, right? Now, the Python "equivalent" of that would be: foo = [0, 0, 0, 0] Still no magic numbers. However, in Python, that same thing can be written like this: foo = [0] * 4 And now we DO have a magic number. Or do we? I'm guessing this and other similar things are present on these and other languages.

Could this possibly be because I did not specify the number of headers? This would naturally be a single header for every letter in the alphabet.

  - by Arms

  I have a scores table that has two fields: user_id score I'm fetching specific rows that match a list of user_id's. How can I determine a rank for each row relative to the total number of rows, based on score? The rows in the result set are not necessarily sequential (the scores will vary widely from one row to the next). I'm not sure if this matters, but user_id is a unique field.
