Comparison of the advantages and disadvantages of formal methods and under-formalized methodsFormal Description:Advantages: 1. Concise and accurate description of physical phenomena, the object is the result of action.2. Can be smoothed over between different software engineering activities.3. It provides a means of high-level confirmation.Cons: Most formal specifications mainly focus on the system's functional data, while timing problems, control and behavior requirements are more difficult to

Why is the software development cycle always estimated at two or three times times?① Independent development. Generally if there is no customer experience and demand survey analysis, during the trial operation will expose a lot of common problems, serious time may also have pushed to the back of the situation. Like Michael Wolfe on January 28, 2012 in Quora, a group of friends to visit another friend, have been expected to arrive at a friend's house to eat lunch, but walk to find out how unreali

How does the shopping site set up the layout?Knowledge of the front end of the recent study a site's layout is one of the key to attracting users to browse. So long have to mention the eight golden rules of interface design: Ensure consistency as much as possible Meets Universal availability Provide information-rich feedback Design Notes dialog box to generate end information Prevention of errors Allows for easy reverse operation Support for internal control points Red

The difference between coder and hacker?Coder: The task form of the engineer, just like some students to complete the teacher assigned to the job, the hope that the most efficient way to finish, there is a certain foundation, can do their own, preferably a model can be consulted, the level is general, but can solve the problem.Hacker: Engineers in the form of research, more purposefully write programs, most of them have areas of expertise. Like graduate students, do not necessarily like their ow

Silly greedy problem.First, according to the order of the points from the big to the small, the same score according to the cutoff date from small to large order. Then, in order, start looking for the time that is not occupied from the due date.

the birth of the Linux kernel officially.In 1993, about 100 programmers took part in the Linux kernel code writing/modification work.In March 1994, Linux1.0 released a code volume of 170,000 lines.In January 1995, Bob Young founded Redhat (Little Red Riding Hood), with Gnu/linux as the core, with more than 400 open-source program modules, developed a brand-name Linux, the Redhat Linux, called Linux "Distribution", Sold on the market.In June 1996, the Linux 2.0 kernel was released with approxima

characteristics.A: Operating system features: (1) Concurrency: can effectively improve the utilization of resources in the operating system, increase the throughput of the system(2) Sharing: Resources in the system are available for common use in multiple concurrent execution processes in memory(3) Virtualization: The ability to turn a physical entity into a number of logical counterparts through a technology becomes "virtual"(4) Asynchrony: The process is moving forward at unpredictable speed.

Regarding our project, our project is intended to be an adjunct to the teaching of the site, for the site, we do not have the experience of the students of this project. I think it is necessary to write the software Requirements specification, to find out what we need to do this project, do not need to do anything, to understand the need to have the direction of effort. In addition, leisure time to self-study database, HEML and other professional knowledge. Then, everyone to participate in each

script, it is also easy for users to use.3. Performance. C is significantly more efficient than Java, because C is compiled, the source code is compiled directly into the machine, and Java is interpreted, the source code is compiled into binary pseudocode, interpreted by the Java Virtual Machine execution.

Hello everyone, my name is Sari, is a student of computer science and technology from Shenyang University of Aeronautics and Astronautics, and I am delighted to discuss and study with you here.I have two hopes for this course of studying software engineering.First: I hope this process is smooth, this course is a smooth course, I can pass smoothly.Second: I hope that through this study, understand as a software engineer thinking behavior pattern, although in the future work I may not be as a soft
