Yeah, I have no much time as I would like, but I am an expert in taking advantage of the little I have. I hate lost my time in a plane let alone in a airport. It's not my first time coding in a plane, in another times I commited from Miami, New York, Nicaragua and in the middle of the ocean, but when you work 8 or 10 hours per day, your batery is empty and it's very dificult code with your mind far away of the reality, so a bit of time is enough to code something and commit when I have a internet connection (I love git).
The most of times I work on weekends, there is the evidence, this is the reason of our slow development. But, we do our best effort every free second we have.
