For me, I would reduce the functionality to just one key: ESC. I always pressed ESC key mindlessly when thinking of the next thing to write. I pressed too many useless ESC like fidgeting. If I can offload it to the foot...
I highly recommend this book. The chapters were "bite sized". Compared with the dinosaur book, it was easier to finish one chapter after I started on it. The chapters on concurrency made me cry with "so this is how XXX works" a lot. I also found the references near the end of each chapter were full of gems.
I self-taught CS, so not surprisingly there were lots of "void" and "dots" in my knowledge space. This book connected lots of dots together.
This is just wishful thinking in the current situation. Don’t expect Chinese government to reverse what it has been doing for years in this political shitshow. Chinese living in US are unfortunately sandwiched in the between and helpless.
