use XML as the message transmission format, including some web service users. One way to compress XML is to adopt a binary re-designed format. The leading candidate is ISO/ITU ASN.1, a data transmission standard that comes before XML. The updated ASN.1 provides some XML-related capabilities, which can re-express the XML format into a special form, such as ASN.1 Packed Encoding Rules, it defines a very compact binary code. Oasis ubl is an example. T

[Java Basics] use the java.util.zip package to compress and decompress filesThe import java.util.zip. * package in Java API contains all Java operations on compressed files. We can use the methods in this package to perform File compression and decompression operations based on the relevant knowledge in IO. Each compressed file in ZipFilejava can be represented by ZipFile. File file = new File ("F:/zippath.zip"); ZipFile zipFile = new ZipFile (file);

The code in build. js calls the UglifyJS interface function to execute the compression task.1. Go to github to download the latest UglifyJS. Two download Methods: If git is installed, go to the git console and use the following commandGit clone git: // github.com/mishoo/UglifyJS.gitOr use http to download the file and click zip to download the file. After decompression, the directory structure is as follows: 2. Create a project (folder) myApp and copy the uglify-js.js and lib directories to yo

This is a reliable method for small memory processing-zram. It looks like a compressed biscuit. Although a small biscuit does not look big (zram's compressed page occupies memory), it feels full when drinking water (releasing the content of a page ). 1. Introduction 2. How to enable 3. Workflow 4. What else can I do? Introduction: Zram does not replace the page to external storage when a swap event occurs. The external storage in the mobile phone is emmc, and the external storage in the compute
