Through a semester to do, do high school such learning methods, deeply feel and usually listen to the different ways of learning, harvest a lot. I still have a few minor problems after studying the book of construction. ’1, the successful software always solves the urgent needs of our life, but different people have different needs, how we weigh the various needs, take out the most core requirements, how can we complete a good demand analysis?2, in the actual production of software, the appearan

With the help of many teachers, we have the honor to learn the new work of Xin Zou, the law of construction, in this semester. Start reading this book, the greatest feeling of the experience is software engineering originally can learn, before the course of learning software engineering, always feel this course and boring, always say too much theory, rarely involve practice, or even no practice this link, so learning is very boring, But the Graduate s

It took a few hours to read the 6~7 chapter of the Law of construction. It can be said that this book brings me not only a supplement of knowledge, but also to understand the software's step-by-step update process details.The sixth chapter:the word "agile process " is the first to think of fast, agile, efficient processes. Results after reading the sixth chapter only, only to find that the brain of the ideas are all wrong, is fundamentally different f

A few weeks ago, I read an article in which a teacher taught his students to actively read literary literature, in which I admired his sentence: "Just think of liturature as if you ' re reading a long text-message". Extended to here, compared to find themselves in real life really rarely take the time to examine their professional books after class, said ashamed, this situation occurs most frequently is the final preparation for the exam. Because of this homework, I seem to tell myself that this

Dimitri Law:If two classes do not have to communicate directly with each other, then these two classes do not have a direct interaction.If one of the classes needs to invoke a method of another class, the call can be forwarded through a third party.The Dimitri rule first emphasizes the premise that each class should minimize the access rights of the members in the structure design of the class, that is to say, a class is packaged wellOwn private state, do not need to let other classes know the f

consistent goal, and a clear division of labor, mutual reliance on cooperation to complete the task, which can greatly improve the software production time and software utilization. The fifth chapter of the book chapter has several software team models.5: Summarize, and consider the way you want to go in the future:Oneself actually mastered how much, understand how much, will use how much, only own heart only clear. Do not work hard, even if the university reading will not exceed the present ap

after reading the 1-5 chapters of the Law of construction, I found that this book is a very good interpretation of our software engineering, there are many brilliant ideas and suggestions here, let me read after the feeling quite deep, although I read the first five chapters, but my passion has been ignited, I found that I have been deeply in love with this book, The intense curiosity compelled me to look down quickly. But I still first temporarily su

Today I read the Xin Zou Teacher's "Construction Law" from the preface to the 66th page of the text, some thoughts and experience are as follows:1. PrefaceFrom the preface, it can be seen that Xin Zou Teacher's orientation to the software engineering course and the evaluation of this book as a textbook are still very high. From the preface can know this book is Xin Zou teacher combines the software engineering teaching experience and own experience in

The possible speedup of the Amdahl ' s law program depends on the part that can be parallelized. If there is no part that can be parallelized, then P=0,speedup=1,no speedup. If all can be parallelized, P=1,speedup is infinite (in thecory). Can get an infinitely large speedup. If 50% can be parallelized, maxmum speedup = 2. If there are n processors in parallel: Parallelize the extensible limit For example p=.50/.90/.99,

Today, I read Chapter 10-12 of the Law of construction. Summed up some of his previous thoughts and practices of the wrong.The person who used to think that the biggest demand for software is definitely our typical user. So you can create a software for these people is equivalent to the software success. But most of the time our software is done and we find that these people don't use our software at all. Why is it? Because it won't work. So when we d

What is software engineering?What is the relationship between software engineering and computer science?The introduction of the book "Building Law: Modern Software Engineering" is mainly about these two problems. Software engineering is the process of applying systematic, orderly, and quantifiable methods to the development, operation and maintenance of the system. It includes: Software requirements analysis, software construction, software testing an

When I was ready to look at the book, I was not anxious to go through the content of the article. Because I usually read the habit of reading, so I first read the "Law of Construction" the book's catalogue, preface and even reader feedback. After a serious reading, I feel that the first version of the reader's feedback in the preface of the book is a highlight of my appreciation after reading the whole book. I have never seen this book before the read

Because of the uniqueness of high-purity silicon, the higher the integration level, the lower the transistor price, which leads to the economic benefits of Moore's Law. In early 1960s, a transistor costs about $10, however, as the transistor gets smaller and smaller, the price of each transistor is only 1000 cents when it can be placed on a hair wire up to 1‰ transistors. According to statistics, ibm704 computers cost 1 US dollars and ibm709 is reduce
