Do you know these five useful but little-known Python modules?
Article Introduction:Text The Python standard library has over 200 modules that programmers can import and use in their programs. While the average programmer will have some experience with many of these modules, it's likely that there are some useful ones that they're still unaware of. I've found that many of these modules contain functions that are very useful in a variety of areas. Comparing data sets, collaborating with other functions, and audio processing can all be automated using just Python. Therefore, I have compiled a shortlist of Python modules that you may not know about and have given a proper explanation of these few modules so that you can understand and use them in the future. All these modules have different functions and classes. This article contains several lesser-known functions and classes, so

JPMS: Java Platform Module System
Article Introduction:JPMS stands for Java Platform Module System. This is a new feature in Java9. Our java applications and Java packages can be packaged into Java modules with the help of the Java module system. Java modules allow us to specify which packages of the module and other Java modules should be able to see it. Java module also lists the Java modules required for it to run. Java Platform System is also known as JavaJigsaw or ProjectJigsaw. The name Jigsaw was used at the time of its development. The main purpose of developing this is to make the JRE more modular. JPMS solves several major problems, namely Classpath/JARHell, large-scale single JDK, version conflicts, and security

Linux kernel module
Article Introduction:The Linux kernel uses modular technology. This design can keep the system kernel minimal while ensuring the scalability and maintainability of the kernel. The modular design allows us to load modules into the kernel only when needed to achieve dynamic Kernel tuning. Now let me introduce to you how to operate the kernel. Kernel module storage location The naming method of Linux kernel module files is usually as follows. The kernel modules of the Centos6.3 system are centrally stored in the /lib/modules/uname-r/ directory. View loaded system modules The lsmod command is used to display the current Linux kernel module status. Without any parameters, it will display all currently loaded kernel modules. The three columns of information output are

Python Blockchain Development Guide: Understand the principles and implementation of blockchain in one article
Article Introduction:Blockchain Basics Blockchain is a distributed database that stores data on multiple nodes rather than on a central server. This makes the blockchain highly secure as attackers cannot steal data by attacking a node. Data in the blockchain is stored in the form of blocks. Each block contains a hash, the hash of the previous block, a timestamp, and transaction data. A hash is a unique identifier that can be used to verify the integrity of a block. Blockchain is an ever-growing chain, with each new block added to the end of the chain. This makes the blockchain highly tamper-resistant because once a block is added to the chain, it cannot be modified. Using Python to implement blockchain Using Python to implement blockchain

Github releases golang submodule
Article Introduction:When you publish a repository on github you can use "tags" which make it easier to track in go.mod but for submodules (or multiple modules) the existing github publish method doesn't work. The "main" module will be tagged but "submodules" cannot be referenced through this tag. (Which makes sense since they shouldn't be required to be in lockstep) My question is how do I get Github to tag this submodule with an explicit version? Please note that this is a "private" repository so I cannot publish it as a separate package in golang outside of github
