The development history of wireless mice
Jun 12, 2024 pm 08:52 PM
Original title: "How does a wireless mouse become wireless?" 》Wireless mice have gradually become a standard feature of today’s office computers. From now on, we no longer have to drag long cords around. But, how does a wireless mouse work? Today we will learn about the development history of the No.1 wireless mouse. Did you know that the wireless mouse is now 40 years old? In 1984, Logitech developed the world's first wireless mouse, but this wireless mouse used infrared as a The signal carrier is said to look like the picture below, but later failed due to performance reasons. It was not until ten years later in 1994 that Logitech finally successfully developed a wireless mouse that works at 27MHz. This 27MHz frequency also became the wireless mouse for a long time.
Caching mechanism and application practice in PHP development
May 09, 2024 pm 01:30 PM
In PHP development, the caching mechanism improves performance by temporarily storing frequently accessed data in memory or disk, thereby reducing the number of database accesses. Cache types mainly include memory, file and database cache. Caching can be implemented in PHP using built-in functions or third-party libraries, such as cache_get() and Memcache. Common practical applications include caching database query results to optimize query performance and caching page output to speed up rendering. The caching mechanism effectively improves website response speed, enhances user experience and reduces server load.
The main peak of Changbai Mountain can access the Internet normally: Jilin Mobile and ZTE completed 2.6G + 700M three-carrier aggregation for commercial use, with a peak rate of more than 2.53Gbps
Jul 25, 2024 pm 01:20 PM
According to news on July 25, Jilin Mobile and ZTE have completed commercial use of three-carrier aggregation based on the 2.6G frequency band (100+60M) and the 700M frequency band (30M) on the main peak of Changbai Mountain. The peak rate in field testing can reach more than 2.53Gbps. Officials pointed out that Changbai Mountain is one of the top ten famous mountains in China. It is now a national AAAAA tourist attraction, a world geological park, a world biosphere reserve, and the world's best nature reserve. The number of tourists received in 2023 will reach 2.7477 million, and 3CC will be deployed this time. It will greatly meet users’ network needs. According to reports, Jilin Mobile has taken the lead in completing the carrier aggregation pilot of a three-carrier network in the 2.6G (100+60M) plus 4.9G (100M) frequency band in early 2024, with peak downloads

First you need to set the system language to Simplified Chinese display and restart. Of course, if you have changed the display language to Simplified Chinese before, you can just skip this step. Next, start operating the registry, regedit.exe, directly navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlNlsLanguage in the left navigation bar or the upper address bar, and then modify the InstallLanguage key value and Default key value to 0804 (if you want to change it to English en-us, you need First set the system display language to en-us, restart the system and then change everything to 0409) You must restart the system at this point.
AMD releases 24.7.1 driver update: 'Only: Path of the Goddess' performance improves by 16%, supports 'Zero' game
Jul 20, 2024 pm 02:52 PM
According to news from this site on July 20, AMD yesterday (July 19) released the latest AMDSoftware: Adrenalin Edition 24.7.1 driver update, which supports "Only: Path of the Goddess" (compared to the previous version, performance increased by up to 16%) and " Zone Zero" game. AMD's driver update also introduced Radeon Anti-Lag2 technology for the "DOTA2" game. AMD officially stated that after installing this driver for discrete graphics cards and core displays with AMD RDNA architecture, input delays can be further reduced and the gaming experience improved. AMD has also fixed a lot of bugs in the new driver. The information is as follows: Improved enabling AMD Radeon™ Anti-Lag and AMDFi
Windows disables forced driver signature to solve the problem that individual device drivers cannot be installed normally.
Jun 19, 2024 am 07:22 AM
Driver signature, also called driver digital signature, is completed by Microsoft's Windows Hardware Device Quality Laboratory. Hardware developers submit their hardware devices and corresponding drivers to the laboratory, which will test them. After passing the test, the laboratory will add a digital signature to the driver. Since the digital signature is done by Microsoft. The computer needs to have the driver installed before it can be used normally. Sometimes it is found that the downloaded driver cannot be installed without a digital signature. This is because the system blocks the installation of uncertified drivers for security reasons. However, sometimes some special devices fail to pass the verification. driver, then obviously only by temporarily turning off digital signature can the installation be normal. Let’s take a look at how to disable driver signature enforcement
A comprehensive guide to learning and applying golang framework source code
Jun 01, 2024 pm 10:31 PM
By understanding the Golang framework source code, developers can master the essence of the language and expand the framework's functions. First, get the source code and become familiar with its directory structure. Second, read the code, trace the execution flow, and understand dependencies. Practical examples show how to apply this knowledge: create custom middleware and extend the routing system. Best practices include learning step-by-step, avoiding mindless copy-pasting, utilizing tools, and referring to online resources.
