software engineering simply speaking, the less practical the more people are not suitable for learning software engineering, the more need to plan the overall grasp of the global time the more need to learn software engineering. Software Engineering covers a very complex element, can have management, process, development model, estimation, analysis and design methods. This will undoubtedly expand the breadth of knowledge, once there is no foundation, it is easy to become armchair, rhetoric.

The Dimitri rule (law of Demeter, LoD), also known as the minimum knowledge principle (least knowledge principle, LKP), has several defining methods, several of which are typically defined as follows: (1) Don't Talk to "strangers". (2) communicate only with your direct friends. (3) Each software unit has the least knowledge of the other units, and is limited to the software units which are closely related to the unit. (4) An object should have as

Transferred from: space of Lord Wei"Murphy's Law", "Parkinson's Theorem", and "Peter's Principles" are also known as the three most outstanding discoveries in Western culture in the 20th century.1. The original sentence of Murphy's Law is as follows: if there are two or more ways to do something, and one of those ways can result in a catastrophe, then someone will do it.

strategies. Fund Investment Rule 1: invest as much as possible in stock funds Peter Lynch is a famous stock-picking fund manager. His preference for stocks has always been implemented. Lynch's first suggestion to fund investors is to invest as much as possible in stock funds. The reason for rule 1 is that from the long-term development of the securities market, the average return rate of stock assets is much higher than that of other types of assets. Therefore, if an investor regards inve

Glossary of property law Property RightIt refers to the right of a natural person or legal person to directly control real estate or movable property, including the right of ownership, the right of interest in use, and the right of guarantee. Real estate refers to land, buildings, and other land attachments; movable property refers to things other than real estate. Formulating property law is of great si

At first, I thought this question was a raw question about the rapid power of the matrix, Later it was found that it would time out, and the super would exceed M = C ^ (N * n). This operation, and the C itself is a matrix of N * n, with N at the maximum of 1000. But here is a clever place: the source of C is actually = a * B. A is a matrix of N * k, and B is a matrix of K * n, K is up to 10. Here is the breakthrough. The combination Law of the matrix

This is the story I saw in an article on Tujia: Sao Paulo, Brazil, has a town named yarama. There is a strange law in the town of yarama: if one of the people living in this town steals food from poverty, all the adults in this town will be fined RMB 5, and All fines will be used for charity. This rule originated from one thing that occurred in the town of yarama in 1968: In 1968, Arama, an old woman begging on the street was caught while stealing b

has k Positive probabilities: Some mathematical symbols Do not confuse data with computer programming symbols. For example, in the flip die example, the probability of 2 or 4 points is calculated as: P (2 then 4) = P (2) + P (4 ), this is the Union symbol, which is equivalent to "or", and the intersection symbol is "and", which is different in Chinese and English. Another example is flip 2 dice, which adds up to seven points. The probability of one point and one six points is obtained, and P (

If you think that success is possible only when you are busy and busy, you are wrong.Things always develop in a complicated direction, and complexity will lead to waste, while efficiency comes from simplicity. Most of the things you have done may be meaningless. A truly effective activity is only a small part, and they are usually hidden in complicated things. Finding the key and removing unnecessary activities is not that complicated.Occam Razor: do not add any entity if necessary.In the 12th c

What can heap do from the perspective of variable governance and problem simplification? 1) priority queue 2) Heap sorting On the basis of implementing the heap, these two are also very simple.

In the face of our little experience in software development, this book, software engineering is no longer dull, but it becomes surprisingly lively and interesting. Learn a lot of professional courses, such as algorithms, data structures, compiling principles, software engineering and so on. Our classmates may have this question in mind: what is the use of learning so many lessons? How many of them are actually applied to the job? In other words, we all feel that there is an insurmountable gap b
