This year we removed 26 blog sites from the previous list that does not meet our active criterion: at least one blog in the last 3 months (since Oct 1, 2016). We also added ten new relevant blogs to the list. All blogs in this list are categorized into two groups: very active and moderately active. The former often have several entries each month while the latter may only have one post for a few months recently. We also separate blogs that do not involve much in technical discussions as in a Others group. Within each group of blogs, we list in alphabetical order.
