1 , what is a server clusterIn a nutshell, a collection of servers that combine multiple servers together to achieve specific functionality for a particular purpose , that is, server clusters, which are all Linux -based systems, we can call this cluster a Linux cluster. 2 , why use a clusterFor example, now that you have a server, deploy this server as LAMP or lnmp, and then set up a site, has just started to have a connection of more than four concurrent access, the server can provide normal
To give you illustrator software users to detailed analysis of the use of shrinkage and expansion effect of the experience of the skills.
Tutorial Sharing:
The shrinkage and expansion effect of Illustrator can help us to bring a better visual effect. Now let's talk about the skills of the Adobe Illustrator (AI) shrinkage and expansion effect.
Python supports the 3rd party expansion package implemented by C + +, which is especially important when performance requirements are high.This article explains the basic steps for customizing the Python expansion pack with an example.1. Extension package source code implementationfollow the steps in the Python website tutorial extending python with C or C + +, where the source file for the extension module
This paper introduces the horizontal touch sliding effect of single line text, and realizes the horizontal sliding effect of textview text by EditText.
This article continues to introduce multiple lines of text folding expansion, custom layout view implementation for multiline text folding and expansion

In the last blog post, you get a byte array of compressed data by decompressing and merging the compressed chunks. From now on, this data will be processed.

This is because the layout of the flexbox expansion box is so powerful that I didn't care about it as an attribute of display.To solve this layout problem, we should first understand some basic problems. Let's first review the attributes of display:None: hides an object. Unlike the hidden value of the visibility attribute, it does not reserve its physical space for hidden objects.Inline: specifies the object as an inline element. Block: specif
operations for mathematical morphology: expansion, corrosion, opening and closing. They are featured in binary images and grayscale images. Based on these basic operations, it can be deduced and combined into practical algorithms of mathematical morphology.(1) Two-value morphologyThe morphological transformation of binary images in mathematical morphology is a processing process for sets. The essence of its morphological operator is to express the in
The principle of thermal expansion is described as follows:
1) change the temperature of the material and use its expansion or contraction effect;2) use various materials with different thermal expansion coefficients;
Thermal expansion and contraction are physical phenomena that we are very familiar with. The thermal
We often add expansion packs to existing projects, sometimes because of incorrect documentation, such as from this document:composer updateThis command, in our present logic, can cause great damage to the project.Because composer update the logic is to update all expansion packs to the latest version according to the extension package version rules specified by Composer.json, note 所有扩展包 that, for example

LVM is a local volume manager applied to the Linux kernel, the full name is logical Volume Manager. Linux LVM has two available versions, lvm-1 and Lvm-2,lvm-1 only available on Linux kernel 2.4, which provides the most basic logical volume management, and Lvm-2 is an updated version of Lvm-1, which provides additional functionality outside of the standard lvm-1 functionality.The basic modules of LVM are:Physical volume (PV) physical volume, Volume Group (VG) volume group, Logical Volume (LV) Lo
