Synology NAS storage to create storage space Preface: We have previously installed DSM and logged in to NAS via browser The first thing we're going to do is create a space to hold the data, which is important because it's a must. The data you want to store is in the space created now. One: Log in to the NAS admin interface, as shown in Figure 1 below: Figure 1 Two: Click on the position shown in Figure

Differences Between Auto-incrementing primary keys of mysql Storage types and primary keys of mysql Storage Q: if there is a table with an auto-increment primary key whose field is id, after 10 data entries have been inserted into the table, the data with id and 10 has been deleted, restart mysql and insert a data record. What is the id of the data record, which is 8 or 11?A: If the table type is MyISAM, i

We know that there are common file name detection vulnerabilities and file format check vulnerabilities. There is also a file storage vulnerability. We know that there are common file name detection vulnerabilities and file format check vulnerabilities. There is also a file storage vulnerability. This type of vulnerability mainly allows users to read the input path name and use incorrect filtering meth

Usage scenarios:1. When copying files, it is common for a thread to call an interface to copy files, which requires caching the data, and if each file needs to create a separate cache, the memory fragmentation is large.If you create a static memory area, when multithreading calls the same interface, multiple threads using the same static cache can cause data pollution. The best way is that the cache is visible only to this thread,Creates a buffer when the thread is created and destroys the buffe

Today, I saw a small program in unix network programming, which is very enlightening. Int check_cpu () {Union {Short;Char B;} C;C. a = 1;Return c. B = 1; } If it is a small-end storage, 1 is returned, and the large-end storage returns 0. I feel that this function is clever and uses the characteristics of union to determine the memory storage format. Union p

Collation The previous article introduced the advanced copy feature of the storage system and briefly introduced several different methods of advanced copy. They are equivalent copy (EC), one point copy (OPC), snapopc +, and quickopc. This article will further explain equivalent copy (EC ). Body Equivalent copy is the image data that is created or maintained to synchronize with the actual business data. It can maintain real-time synchronization, but i

Location of integer Object Storage in Python, and python integer Object Storage Python integer objects are stored in different locations. Some of them are stored in a certain storage, while others are used to open up space. For the reason of this sentence, you can look at the following code: A = 5 B = 5 A is B # True A = 500 B = 500 A is B # False Th

Generally, the size of each slice is 512 bytes, but to improve efficiency, when reading a hard disk, the operating system often reads multiple sectors at a time (mult

There are five ways to store data on the Android platform:1. File storage data;2. Use sharedpreferences to store data;3. SQLite database stores data;4. Use contentprovider to store data;5. network storage data;Here we will introduce file storage:The file storage method is a commonly used method. It reads/writes files in Android and implements I/OProgramIs exactly

Scene:1. You need to count the number of objects created on a thread.2. When the heap space is created, it needs to be destroyed based on the thread needs to be created and ended.3. Because the scope is that a thread can only see its own stored data, it does not require a critical section or mutex to maintain its own heap memory. Join if implemented with global STD::MAP, you must lock on put and get, which is a waste of resources.4. Can be used to maintain a connection, such as a socket,database
