Hodgepodge

1. Technical Practice

Http://icodeit.org/2016/02/pitfall-of-technology/?hmsr=toutiao.io&utm_medium=toutiao.io&utm_source= Toutiao.io

Key points: Today we live in the era of the explosion of news, especially the Internet industry, new technologies and new products. As a technician, there is more or less deep inside the grasp of all the technology, but the human energy is limited after all, must have a moderate focus on some technology, only understood knowledge is helpful. Let's take a look at the author's coping methods.

2. Talking about: The relationship between Software architect and mathematics

http://mp.weixin.qq.com/s?__biz=MzA5Nzc4OTA1Mw==&mid=408978072&idx=1&sn= F745dba7c543d16250fb8e851d2806bb&scene=0#wechat_redirect

Important: For the developers who are biased towards the project, the mathematical knowledge is not used so much, so much knowledge is returned to the teacher. But this is not to say that the architecture of the students do not need mathematics, there may be many times we do not need to understand the mathematical formula theorem is so profound, but we need to maintain the mathematical quality, some code only after the mathematical proof to make us feel invulnerable.
