1. Teaching Material 2nd Chapter 2.1My question is about the unit test in writing good program software, the textbook says that unit test should design test cases of all important control paths in the module, in order to find errors inside the module, and unit test should ensure the correctness of the basic module of the program accurately and quickly.Question: It's time-consuming to write a program software, why do you have to unit-test it?A: Because
Zhang Sheng Teacher's "mathematical analysis of the new talk" for the best. I personally think that the "Math Analysis course" of the Department of Mathematics is also good, at least in the typical South style, we look cordial. It's OK to learn whichever one you want. In case your maths is too good, the two books are not enough to eat, then go to see Fihkingorts "Calculus Tutorial" well--but I think there is no need, after all, you do not want to transfer to the math department.Demidovich's "Ma

Information Leakage Prevention is an overall solution that includes encryption, management, auditing, monitoring, and other aspects. Information Leakage Prevention requires "Combination boxing ". However, whether it is encryption, management, audit or monitoring, there are single-function products on the market. In this regard, are enterprises buying multiple single-function products combined into an information leakage prevention system, or are they
. What can we do here?
1. for common application scenarios, such as file operations, command line operations, database operations, user permissions, and authentication, we need to understand the implementation of the framework and provide corresponding security coding examples.
The example given in the framework document is not necessarily the best. Security workers must train programmers in security awareness to learn how to use the APIs of the framework to securely combine common functions.
