About the authors …
… we would like to share some hacks we collected or developed to solve problems we faced to. We wish these pages may be helpful to you no to waste your time in solving the same problems, so that you can use it more profitably investigating something new.
If you have suggestions, questions, or hacks write us. We would be pleased to share them in these pages.
The flame of a candle cannot light up the whole Universe, but the rays of light can travel long before reaching their final end. We hope our work can travel as much as those rays.
