This year, I enthusiastically joined the B2B book club organized by Digital Marketing Connect (DMC) to continue expanding my learning field. (The last time I seriously read a marketing book was probably Philip Kotler’s Management Marketing during the remote reading club with Bob in college.)

Recently, Arizona has been a hot keyword due to tsmc’s (then rumored to be lowercase “t”) plans to establish a manufacturing plant there. Coincidentally, the selected book for the first few months of the book club is <Influence: The Psychology of Persuasion> by Dr. Robert B. Cialdini from Arizona State University, published in 1984. It seems to have had a significant influence on the marketing field for more than thirty years and is often cited as a reference in marketing-related materials (but it is also possible that I started looking for related information from this book).

Notes: COVID-19 Contact Tracing Technology

(Context: Wherever we walk, you will leave traces, would we leave some sort of traces after nearby contact? Image source.)

Apple and Google jointly published a press release about: “Apple and Google partner on COVID-19 contact tracing technology” on April 10, 2020. Also provide APIs of both Apple iOS and Google Android platforms, and corresponding technical documents: Contact Tracing Bluetooth SpecificationContact Tracing Cryptography Specification.

I guess there could be some Flutter plugins based on it very soon. :)

This is a personal reading notes. I would like to start with privacy and Bluetooth specification documents. I want to learn and practice how to plan and organize such kind of solution architecture to resolve some challenges in the future.

The content of this reading notes will include my personal observation and comments. The purpose of taking notes is to improve my learning efficiency and keep the habit of sharing.
