Deep Neural Network (DNN) is an artificial neural network, which is characterized by having multiple layers of neurons, which can better handle complex nonlinear problems. In Java, we can use open source libraries such as Deeplearning4j (DL4J) to implement deep neural networks. In DL4J, a basic deep neural network consists of multiple layers, each containing […]

Having been engaged in distributed work for more than 10 years, this book has subverted my understanding | Bonus book at the end of the article
I have been working on distributed system architecture for more than ten years. I am not only familiar with common distributed frameworks such as Zookeeper, but also familiar with the split-brain problem, CAP theory, Paxos and Raft algorithms, so I think I have some understanding of distributed systems. However, Teacher Jiang Feng’s book “Distributed High […]

Stop encapsulating various Util tool classes, this god-level framework is worth having!
Source: ryanc.cc/archives/hutool-java-tools-lib Today I would like to recommend a very easy-to-use Java tool library. It contains basically all common enterprise-level tool classes. It can avoid reinventing the wheel and save a lot of development time. It is very good and worth knowing and using. Hutool is homophonic to “muddleheaded”, which means pursuing the state of […]
About the problem of Android not having file storage permission to save files
I found that there are some Android apps that can save files without applying for file storage permissions. I read a lot of articles and summarized them as follows: Foreword: Starting with Android 10, Android introduces a new storage permissions model, where apps need to explicitly request runtime permissions to access external storage. In this […]

Are you having a headache due to circular dependencies between SpringBeans?
Circular dependency—circular dependency & amp; circular reference Circular dependency between Java libraries, that is, Java package circular dependency, refers to when two or more jar files directly or indirectly depend on each other (circular dependency). Circular dependencies can cause problems during compilation or runtime of your application and can be difficult to resolve. The circular […]

14 top Spring MVC tips, keep using them and keep having fun!
Normally, in Spring MVC, we write a controller class to handle requests from clients. The controller then calls the business class to handle business-related tasks and then redirects the client to the logical view name, which is parsed by Spring’s scheduler servlet to render the results or output. This completes the typical request-response cycle round […]
