Scrum is a framework for developing and sustaining complex products and is an incremental, iterative development process. Scrum takes empirical Process Control theory (empiricism) as the theoretical basis of the process. Empiricism argues that knowledge originates from experience, and that decisions are made based on known things. Scrum uses an iterative, incremental approach to optimize predictability and control risk. The sixth chapter focuses on the Agile process Overview: The first step: Fin

Only for the ticket machine should not be in the field of software engineering research, because it does not conform to the code of ethics. The profession of software engineering is moral standard, the engineer should take the public interest as the core of all work, and cannot contradict with morals. But for the school's elective system and train ticket purchase system, such as can make the ticket-making system, the system develo

, while the project is in such a direction that the specific behavior of the decision-making, the project is not Boss the. Eighth. The Hand of God begins with the simplest programming, to the organization development of the engineering team. Implementation is the ultimate goal. It is precisely because of the needs of the implementation, we have designed some data structure or logical structure of the generation, and the emergence of a team organization model, the emergence of a process model, th

setcompressionmapoutput () and Setmapoutputcompressorclass ().(4) reusing the JVMHadoop starts with version 0.19.0, allowing the JVM to be reused among multiple tasks of the same job. Therefore, the start-up cost is split across multiple tasks. A new property (Mapred.job.reuse.jvm.num.tasks) specifies the maximum number of tasks a JVM can run. The default value is 1, at which time the JVM cannot be reused. You can increase the property value to enable JVM reuse. If you set it to-1, it means the

can be implemented by any class. Protocol (PROTOCOL) is not a real class, it can only declare methods and cannot add data. 43. Category and class extensions are continuation extensions of class inheritance.44, inherit the implementation of the base class do not forget to call super. 1. Call the base class method to use the services provided by this class. 2. Override the method of the base class in order to introduce your own code into the defined program model. 3. If you intend t

1. Use constructors to ensure initializationThe client programmer must call the structure of the initialization object before using the object, but they tend to forget it, which can be left to the library programmer for Automatic processing. This is the constructor. The name of the function is the same as the name of the class, and the compiler can recognize it.2. Use destructors to ensure cleanupConstructors and destructors are not return values, and the void return value differs from the gener

observer is observing the surrounding situation, the Observer has been in (0,0) position. The title gives you the center of the tree, which has a radius of more than 1 per second, and if the trees collide or touch the observer, they stop growing and they block the observer's gaze, and the question is, when is the observer blocked? If you can't stop, output -1.Ideas:First, you can preprocess each tree when it stops growing, that is, each tree and all the other trees to calculate a time to minimi
