A few days ago, watch and CAI Tou talk about the concept of “dehydration”. This concept is simply put, received things do not use, then it is not yours, to use, then you can be regarded as a harvest of something. The word “use” can be used extensively, for example, to write notes/lessons/inferences. Anyway, you need to do something with it to prove that you’ve actually learned this thing. The process of doing this is the process of this thing growing into yourself. So NOW I will try to write demo when I learn technology, and I will try to record technical points, such as anti-jitter and Throttling I wrote a few days ago. I don’t expect these articles to be useful to anyone else. I’m just superstitious, and CAI Tou is right, that you do learn something and then do it.
