, and what investments are made when a product line is created? The choice of different variants in the product line is expected to be rewarded. In particular, it is possible to develop the smallest useful product before expanding it. Security: Whether the product requires user authentication or must restrict access to the data. How data security is guaranteed. How to withstand DDoS attacks or other attacks. The architect is playing a compromise gam

Here, he interviewed Anders Hejlsberg, a famous engineer and chief architect of Microsoft. Net Framework C # language. Anders Hejlsberg is widely known for designing Turbo Pascal, one of the earliest languages on PCs. He licensed Turbo Pascal to Borland and led the team to create Delphi, an extremely successful visual client/server applicatio

Alibaba architect of "big talk architecture" shares the technical points that Java Programmers need to break through. Alibaba javaI. Source Code Analysis Source code analysis is a critical knowledge that can remain unchanged. source code analysis is boring and difficult for many people. I think there are three core points in the source code reading: technical foundation + strong curiosity + patience. I think it is the core driving force for reading so

First, you must learn the basics of object-oriented1. Reduce the complexity of software development2. Improve the efficiency of software development3. Improve the quality of software: maintainability, scalability, reusability, etc.Improve software quality: maintainability, extensibility, reusability, and so on, the specific point, is high cohesion, low coupling, object-oriented is to solve the 3rd problem. Therefore, to become a good programmer, the most inseparable is the object-oriented.Second

reasonable allocation of server resources Cpu:apache MySQL in high-load environment, disk IO read and write too much, will certainly occupy a lot of resources, it is inevitable that the CPU occupies too high. Memory: Memory library, database software hard disk: file web2.0 architecture Select MongoDB+redis or mysql+Memcached is a better combination, the logic is simple to use NoSQL current main web site architecture LAMP, LNMP, LLMP now there is a lnamp architecture on the network, which is the

Because T1 got the lock will not be released after the T1 10 cycles before releasing the lock, the size is already 10, T2 execution is late.But using the wait word has a problem, not real-time, mentioned above, must wait for a thread to execute another line friend receive notification.It should be replaced with the code Countdownlatch which is not commented ou

, type grammar, type 1 grammar including 2, type grammar, 2 grammar including Type 3 grammarSummaryThe grammar and the knowledge we have lifted are actually very much connected, for example, we did not learn a language. We found. The underlying content is all the same, as long as writing different code styles varies, we call it syntax, and we infer that this is Java writing code or C # writing code. Sometimes the difficulty is that syntax is a set of prescribed formats, and if only this lattice

reused multiple times. Helps reduce the level of functional repetition.Extension Use CasesA use case can be used to extend the behavior of another use case, usually in special cases. For example, suppose that before modifying a particular type of customer order, the user must get a higher level of license and then "get the License" use case will have the option of extending the regular "Modify order" Use Cases. Extension pointsThe join point of an extension use case is defined as an extension p

permission exceptions, we will also open a special section to explain. After such a package, the developer only needs to throw an exception when needed. A novice programmer can easily throw their own exceptions without worrying about what is going on behind the exception.In addition, if the complexity of the system increases, you can increase the subclass of the exception and perform different exception handling. In addition, the system can also perform automatic compensation mechanism, su
