: It's refreshing and nice. :) Are you learning mathematics?Concerning the object-oriented thinking (not programming thinking), I think if you understand the design pattern, you will understand most of it. I am reading it for the second time, but I did not understand it for the first time, now I have found some feelings.Working hard!Split first and then groupThe object-oriented approach only provides a set of methods or thinking tools for designing software.

Or is it a combination of IP and port numbers? If so, what

If the data in one of the tables in your database meets the following criteria, you should consider creating a partitioned table.1. There is a lot of data in a table in the database. What are many concepts? 10,000 lines? 20,000 lines? Or 100,000 or 1 million? This, I think is the question of the benevolent see and the beholder. Of course, when the data in the dat

reflection was that from the company's perspective, the fundamental purpose of the interview was to find someone who could do a good job. "High Education", "Good algorithm", "Good Foundation", and "experienced" are representations rather than fundamentals. They cannot be equal to "good job" directly.. Method The goal is clear, but the following problem is th

ing element of the type void (ABC:) (float) and ABC: AB. The result compiler looks for such a ing element. If yes, enter the corresponding address bar. Otherwise, an error is reported, indicating that only one void ABC: AB (float) {} is incorrect, you must first declare the corresponding ing element through the type definition character. That is, the definition

For example, some interviewers have good knowledge about basic knowledge and algorithms, and have clear concepts such as processes, threads, and memory. They are also familiar with basic data structures and algorithms such as Hash, binary tree, and fast sorting, however, after ente

their own shoes and talk about the quality of the user experience, it's just a subjective feeling. So I never say a word: "Stand on the user's point of view ...". 　　What makes you believe that? The status of "Craftsman" and "division". "I don't think so, I think it's very stingy." When a client says that to you, he is questioning your design, even questioning whether you understand it or not. Now, when

of seemingly meaningless data actually involves all aspects of the company's operation and operation. So I created a form to record all the data reimbursed by the general manager here by time, amount, consumption place, contact person, phone number, and so on.

Code review is a process by which code quality is improved by reviewing codes, which occupies an extremely important position in the XP method, and has become an indispensable part of software engineering. This paper discusses some concepts and experiences of code review, and puts forward some suggestions on how to pay attention to the code review and Code review.

ways.It is associated with the idea of data mining as a process to recognize the novelty of the results. Many of the results of data mining are what we expect-and can be recalled. However, the fact that can be explained does not negate the value of digging out them. Without these experiments, this might not have occurred at all. In fact, only the structures that can be justified by past experience will be
