What is the cause of chassis leakage?

Chassis leakage refers to the leakage of current from the computer chassis during normal use. This may cause current to be conducted to the ground or other parts through the metal shell of the chassis, posing safety risks to users. Case leakage may cause equipment damage, short circuit, or even electric shock. There are many possible reasons for chassis leakage. The following are some common causes: 1. Power supply failure: The power supply of the chassis is an important part of the computer system. If the power supply itself fails, such as power overload, short circuit, etc., it may cause The chassis is leaking electricity. In addition, the power supply

Nginx is currently a widely used web server and reverse proxy software. It supports HTTP, HTTPS, SMTP, POP3 and other protocols, and is often used to build high-performance web server clusters. In addition, Nginx also provides TCP and UDP network communication modules, allowing users to forward the client's TCP traffic to the application server in a reverse proxy manner, thereby achieving TCP load balancing and multiple services sharing the same IP address and Port function. Among them, NginxT

In Go programming, functions have the following security risks: variable parameters lead to buffer overflows, insufficient input validation leads to malicious code injection, and cross-boundary calls lead to type conversion errors. Precautions include limiting parameter variability, performing comprehensive input validation, using safe functions, and limiting cross-boundary calls. Practical cases demonstrate the security risks of cross-boundary calls, showing that attackers can disrupt program behavior by controlling request parameters.

According to news on June 30, with the rapid development of new energy vehicles in China, the number of new energy vehicles on the streets and alleys is also increasing. However, battery safety has always been a concern. Recently, it was reported that a new energy vehicle had a problem of battery falling while driving, which is different from the common fire situation. According to published videos and pictures, the incident appears to have occurred in Chengdu, Sichuan on June 29. A new energy electric vehicle's battery suddenly fell while driving. Despite this, due to the inertia of the vehicle, the vehicle continued to move forward for more than ten meters. The vehicle lost power and the two men had to get out to check on the situation. They looked helpless and called for help. Fortunately, no other serious consequences were caused by this incident.

Recently, Blast has once again become a hot topic in the market. With the end of its "BigBang" developer competition, its TVL has continued to soar, exceeding US$2 billion in one fell swoop, occupying a place on the Layer 2 track. At the same time, Blast also announced that it will launch its mainnet on February 29, causing the public to continue to pay attention to it. After all, the "anticipation of airdrop" has successfully attracted most participants to watch. However, with the development of its ecology, various projects emerge one after another, which also leads to the frequent occurrence of various security risks. Today Beosin will explain to you the security risks and potential opportunities behind Blast’s strong start and the surge in TVL. Blast development history Blast was founded by Blur founder Pacman in 202

Recently, U.S. federal regulators expressed concern that self-driving cars from Cruise, a subsidiary of General Motors, were exhibiting dangerous behavior on the road, triggering a safety investigation into General Motors, according to the U.S. National Highway Traffic Safety Council. (NHTSA) has begun investigating safety flaws in nearly 600 of Cruise's self-driving vehicles. The investigation found the cars may not have taken adequate measures to protect pedestrians on the road, including at crosswalks. This is not the first time Cruise has raised concerns. Earlier, the company was in the spotlight for its driverless taxi service. It is understood that Cruise’s driverless taxi service has been put into operation in the San Francisco Bay Area in the United States.

It is common for everyone to use power banks to charge mobile phones. However, many people often doubt the safety of charging after seeing news about power banks catching fire. So, is it harmful to use a power bank to charge smart devices such as mobile phones? The core principle of safe charging of power bank: The power bank increases the power of the 3.7V battery cell to 5V to charge the mobile phone. Stable battery voltage output ensures stable charging of the phone without damage. Safety of fast-charging power banks: Generally, there are only versatility issues, which do not affect safety, only the charging speed. Precautions when purchasing: Choose well-known brands and purchase through official channels. Avoid being cheap and just have an appropriate capacity. It is recommended to use high-grade polymer physical batteries. Recommendations for use: If the power bank is damaged and squeezed, use with caution. If there is a problem, it is recommended to replace it. Unplug after fully charged
