I've used Matlab on and off before, but I need to develop a good understanding of it now, and the language I'm most familiar with is Python. Care to describe a Matlab language feature, idiom, best practice or philosophy as compared to Python? There's a terrific amount of buzz for and resources pertaining to going the opposite direction...

Hi, I have a long-running Python process that is generating more data than I planned for. My results are stored in a list that will be serialized (pickled) and written to disk when the program completes -- if it gets that far. But at this rate, it's more likely that the list will exhaust all 1+ GB free RAM and the process will crash, lo...
