Preliminary C++ (2) Default parameters, references and inline functions
Introduction C++ is a powerful programming language with rich features to suit various programming needs. This article will introduce three important features in C++: default parameters, references, and inline functions. I will discuss their concepts, features, and usage scenarios in detail, illustrating them with code and comments. 1. Default parameters 1.1 Default parameter concept Default […]
In ffmpeg, why is the network video stream h264 converted to YUV by default instead of other formats?
When making online videos, knowing and clarifying some video programming concepts early will save you a lot of detours. Corresponding to video transcoding and transmission, if you follow the code directly at first, it is easy to feel that you understand everything, but why you do this seems to be explained in detail. For example: […]
Use Terraform to manage existing kubernates and default node pools
background: When creating a cluster through terraform resource “alicloud_cs_managed_kubernetes” “k8s” {…}, a default node pool default-nodepool will be generated, but how to modify the information of this default node pool? Solutions: Because there is no default-nodepool in Terraform’s state file, if you go directly to main.tf to create the node pool default-nodepool, your existing node […]
Set the database to start with spfile by default, and set the database SGA size to 2G and PGA size to 200M.
Check the database default startup file first: SELECT value FROM v$parameter WHERE name = ‘spfile’; It can be seen that the database defaults to SPFILE startup Use the following command to check whether the current session is using SPFILE or PFILE: First, set the MEMORY_TARGET parameter to 0. This will ensure that Oracle does not […]
Scanning scheme for default file system types
1. Introduction Normally, when we need to traverse the entire disk, we will choose to use the interface provided by the system, or call the filesystem module in the standard library or boost library. The traversal method of the filesystem library is relatively simple, so this article only lists the usage of the system traversal […]

C++: Default member function of class ——copy constructor && assignment operator overloading
Table of Contents I. Introduction 2. Copy constructor Concept of copy constructor Copy constructor characteristics Explanation feature 2: The copy constructor has only one parameter and must be passed by reference. Using the pass-by-value method will cause infinite recursive calls. Explanation feature 3: If no definition is displayed, the system generates a default copy constructor. […]
Why does mysql not recommend setting the column default value to null?
The answer you usually hear is that columns using NULL values will invalidate the index, but if you actually test it, you will know that IS NULL will use the index. So There are loopholes in the above statement. Those who are anxious can scroll to the bottom to read the conclusion. Preface Null is […]
