. What's more, the original requirement definition is unreasonable. On the other hand, some people are not capable enough, for example, if the language is disconnected, or you have not developed a complete large program, it is bound to drag the entire group. Previously, it was easy for everyone to overcome and to rely on PM's leadership capabilities. However, the technical level and experience cannot be achieved overnight. Since everyone is here in a professional mix, if the technology is so emb

programming efficiency of Chinese programmers. Is it a "silver bullet? The key to Chinese programming technology is not simply writing Chinese characters for logo use, but the compilation technology of program code must be mastered by yourself, and programming and compilation must develop in a unified manner. I personally think that doing well must be a silver bullet. 11. May I ask how the words "software" and "Software Engineering" appear-when, where, and who? In 1958, Turkey proposed in the

structure diagram, how to draw these images, how to use these images to clearly express the solution to the problem, these images are more suitable for expressing what kind of problems, the similarities and differences of similar images, and the scenarios where they are applicable, such innovation is to express the most abundant content in refined languages. 16.7Entrepreneurship-Stick to the current directionVs.Try more new ideas If my development prospects are good and I find other cool ide

and consider issues such as the following: How good is this design and implementation? Can this code span the compiler and the operating system? Is this library likely to be used by the target users it sets ———— that is the people who work in the area where the library is trying to solve the problem? Is the document clear, complete, and accurate? string and text processing. does the coverage have type safety and so on. Author summary Boost is a community a

interact with the database. our habitual thinking, warehousing needs to accept a request, then query the database to get the data entity, and then convert the data entity to a domain object. People are always lazy, sometimes for the sake of convenience, data entities directly participate in business logic, or even return to the UI. in this diagram, the domain layer, the application layer, the UI layer are not accessible to the data entity, Any manipulation of the domain object is converted to s

whether data should be stripped during the design of persistence classes in nhib.pdf. It provides two implementation methods, which are worth your reference. The discussions in the replies are also very valuable.ROBIN: the first method is used in the anemia domain model. Castle activerecord uses the second method. System architecture using nhib.pdfThe post provides a layered design that compares the "traditional" NH, which has a certain reference v

Discussions about C and C ++ Zhihu once had a discussion about C and C ++ languages. YutianshengThe open-source community has never been very familiar with C ++. Richard Stallman, the founder of the Free Software Foundation, believes that C ++ has syntax ambiguity, which is unnecessary and trivial and may be incompatible with C, and it does not bring any great benefits.Having ambiguous grammar and "gratuitous, trivial, incompatibilities with C (...)

Old discussions, or this mentally retarded problem, Daniel help look at ha. $a =new class (); $b = $a; 1) So $b get a copy of $a or a reference? 2) If $b is a reference $a, then why does $b still exist after $a =null? Is it possible to understand that a copy of the $a is assigned to a $b 3) If you write this $b = $a, the result is completely different: After $a =null, $b is also null. ------Solution-------------------- $b = $a It can be und

" results.How to handle precision loss? Workaround: Use the BigDecimal classNote: You should use a string instead of a double value when constructing a BigDecimal object, or it is still possible to raise the computational precision issue. (why is this?) ）Double, which does not accurately represent 16-bit valid numbers, it makes sense to apply the BigDecimal (String) constructor to create objects when using BigDecimal. In addition, BigDecimal creates objects, and we cannot use traditional + 、-、 *

the function, and the value of the heap address is "Hello World", and the string is stored in The function char * get_memory () is a function that returns a pointer to a value. In general, the meaning of a variable is that it provides a name to a memory store, which allows the program to read and write to the memory. The variable contains two values, an lvalue and a right value. The left value is the name of the memory store, and the right value is the value stored in the store. The probl

In a MySQL query, duplicate values may be included. This is not a problem, but sometimes you may want to list only the different values (distinct). Keyword DISTINCT is used to return only a different value, that is, to go heavy. The usage is also
