Fast capture and 2D image stacking as 3D numpy array with Python and Raspberry Pi

Best practices for writing jobs run through cron

I needed help/advice with a few things: 1. Is there a good example of a well written command line task that gets run routinely from the shell. Job would handle logging and be able to redirect stdout to a stdout file and stderr to a stderr file. 2. I was going to setup a dict with all jobs and

Hi Germano, You may want to use the jedi package which you can find at this link: https://pypi.python.org/pypi/jedi/ I'm not personally involved with the jedi package but I use it within my own editor Vim and my understanding is that it should be useful for Python autocompletion support in any ID

Hi Germano and others, First, sorry for this abrupt post without an intro (I'll write a more proper intro next time) and a possible repeat message.
