I am currently working on writing a book, Python Programming and Numerical Methods: A Guide for Engineers and Scientists. This is a book will be used for the data science efforts at Berkeley Division of Data Sciences here and will be used as the textbook for a course next year.
Therefore, I don't have time to update my blog before I can finish the book. My estimation to finish the book is about April 2019. Hopefully after that, I could continue to work on my blog. Thanks.
