Getting started with Linux: Hard Disk partitioning traps and Countermeasures The reason why I want to write this article is that I have experienced many hard disk partition traps during Linux system tossing. In the last few days, I fell into the trap again and climbed out of the trap for two days. After querying data from multiple parties, I finally understood some concepts of Hard Disk partitioning. Record

Bash arithmetic evaluation and errexit traps Original article: https://www.technovelty.org//linux/bash-arithmetic-evaluation-and-errexit-trap.html In Chapter traps for new players: Count = 0 things = "0 1 0 0 1" for I in $ things; do if [$ I = "1"]; then (count ++ )) fidoneecho "Count is $ {count }" Does it look normal? I may have written this many times. However, this is an unexpected error: (E

Shared memory allows multiple processes to access the same memory space. It is the fastest available IPC format. It is designed to reduce the running efficiency of other communication mechanisms. It is often used in conjunction with other communication mechanisms, such as semaphores, to achieve synchronization and mutual exclusion between processes. Other processes can "Connect" the same shared memory segment to their own address space. All processes can access the addresses in the shared memory

The first use of the Web Trojan Horse to create a Web page, it is using IE browser vulnerabilities. Open the Web Trojan generator, click the "Select" button, then select the Trojan program Mm.exe, generate 2 files: Mm.chm and MM.HTML1). The two files a

Objective I believe we all know that implicit type conversions have the risk of being indexed, and that in the case of high concurrency and large amounts of data, the result of an index is very serious. Dragging the database down, and then crashing the entire system, has been costly for a large system. So here's a good study of the MySQL implicit type of conversion traps and rules. 1. Implicit type-conversion instances Today, the production library

result to the target at the end of the function. So this temporary object is quickly created and quickly released ... A piece of memory was released two times. The consequences are unforeseeable. When you assign the value of an object to another object, if you do not overload the assignment operator, it also results in a bitwise copy. The end result is a wild pointer (a cancer hidden within the class), or the same memory is released several times. Did you see that? Are you scared? Do you feel

Introduction: The goal of transaction processing should be to achieve high data integrity and consistency. This article is the first of a series of articles on developing effective transaction strategies for the Java platform, and describes some common transaction traps that prevent you from achieving this goal. The author of this series, Mark Richards, explains these extremely common errors by using the code examples in the Spring Framework and Enter

When certain conditions exist, the time order in which a thread accesses a resource can lead to unexpected results. This situation is often referred to as a race condition.Mutexes are used in multi-threading to avoid using a common resource at the same time. Many famous examples of race conditions have resulted in disastrous consequences.When two or more threads are stuck forever, waiting for each other to release their own resources, another common pitfall in thread application occurs. This is

One of Asp for JScript traps: character escaping and jscript escaping Incorrect usage: Cause:Because I obtains the value output by path1 and \ is an escape character, I actually obtains the value C: mydirimg, whileAlthough the value of j is C: \ mydir \ img, j is still a js variable, SO \ is still an escape character. It looks like this: Correct usage:

causes the program to crash, which often occurs when the parent class has a kvo, and the parent removes it once in Dealloc, The subclass is again in the case of a remove. Don't think this is a rare occurrence! It is possible when you encapsulate the framework open source for others or collaborative development with multiple people, and this crash is hard to find. I don't know if you found out, the current code in the context field is nil, that can be used to identify whether the KVO is supercla

the program. But using assertions is dangerous, and once the system fails, it hangs.Five, the thinking of the AssertSince the assert is intended to debug a test program and is not used in a formal production environment, it should be considered better to test juint instead of using it, and the juint relative to the Assert key provides more functionality. Of course, debug testing can be done entirely through IDE Debug.In this view, the future of the assert is dim. Therefore, you should avoid usi

Detailed description of deadlock traps when using Python + Java to call Shell scripts, pythonshell Preface A recent requirement is to regularly determine whether the execution conditions of a job meet and trigger a Spark job. When writing a Spark job, it is encapsulated into a Jar package and then passed in the required parameters for execution using Shell scripts, considering that the judgment condition logic is complex, it is not conducive to develo

Common pitfalls and traps for pure Socket (BIO) long link programming, socketbioThis article is purely a summary of my personal experience. The pseudocode is also coded on the whiteboard when I write an article. There may be logic problems. please correct me. Thank you. Internet (Global Internet) is produced by communication between countless machines based on TCP/IP protocol families. TCP/IP protocol families are implemented in four layers: link laye

This trap comes from a requirement that the data needs to be processed asynchronously in the background. After processing, the event that is triggered to be processed is probably written as follows: EmployeeCollection data = += The code is quite simple, and the traps are also in it. Suppose DalHelper. fill (data) throws an exception. raiseEventLoaded () won't be executed and depends on data. the Loaded Event code will not be executed either. This is a
