Calling parent class __init__ with multiple inheritance, what's the right way?
...init__(). (Disclaimer: Avoiding super().__init__() in object-subclasses is my personal recommendation and by no means an agreed-upon consensus in the python community. Some people prefer to use super in every class, arguing that you can always write an adapter if the class doesn't behave as you expe...

I totaly agree and hope my writeup doesn't encourage reinventing the wheel! Though some wheels are kinda new, just beginning to become known and are not well enough explained so that Intermediate level software architects can judge its application f...
Principles for Modeling CouchDB Documents
...ote a nice blog post about methods of modeling "joins" in CouchDB. One of my take-aways was: "The only way to allow non-conflicting addition of related data is by putting that related data into separate documents."

Why is the gets function so dangerous that it should not be used?
...hows in his answer, with fgets() you might have data left over on a line. My wrapper code leaves that data to be read next time; you can readily modify it to gobble the rest of the line of data if you prefer:
if (len > 0 && buffer[len-1] == '\n')

Why is “while ( !feof (file) )” always wrong?
... All that "predictive value" talk... I never thought about it that way. In my world, feof(f) does not PREDICT anything. It states that a PREVIOUS operation has hit the end of the file.
