Inserting patch code also makes the module violate strong cohesion, loose coupling design principles, especially if the project configuration management work is not perfect, recall changes and delete features will also cause proble

External applications include risk control management, CTA policies, algorithm transactions, and other applications. In the application, vyy has designed an application engine to drive various strategy groups and provide services to them. At the same time, the main engine of vyy provides interfaces such as subscription, delegation, withdrawal, and database operations to in
Project background:The log is particularly important to us, but we also know that the system's log output is particularly ugly, so there will be a lot of open-source log analysis software, then we need a simple to use.Lab Environment:Virtual MachinesVMware Workstation playerServer: centos6.5 system ip:192.168.0.25Webalizer.x86_64 0:2.21_02-3.3.el6Experimental processFirst, the

Deep learningThe previous article has been explained. Deep learning is a combination of unsupervised and supervised learning algorithms. Therefore, it is not easy to determine the complexity of space-time.The model parameters of deep learning are generally independent of the data magnitude, but on the one hand, because it is less selective to
software environment can not be burned according to the process of the development stage, so the efficiency is too low and error-prone for large batches. The simpler, the more efficient the single operation, the less prone to error. The best way to do this is to solve it in one step. The recommended way to do this is:
Complete the layout and construction of the entire software environment ac
Software Requirements AnalysisN:Requirement: Sometimes we want to turn the text of the book into word form, but it is either a code word for ourselves or a photo made into PDF format, time-consuming and laborious. Sometimes we want to search the textbook a problem but a lot of symbols do not come out, our software is based on this need to produce, you can scan the text of the book into word document form, t
"Software industry, people-oriented ". The common psychological performance of various personnel involved in the software development process has a significant impact on the entire development process. As a project manager, it is very necessary to analyze it one by one, find out the knot, then remedy the problem, increase communication efforts, and improve development efficiency.
