According to news on May 8, China Telecom held a launch conference for the direct-connect mobile phone satellite service in Hong Kong today, officially announcing the launch of the direct-connect mobile phone satellite service based on Tiantong Satellite System in Hong Kong. According to Xiaomi Mobile’s official WeChat account, Xiaomi Mi 14 Ultra currently supports two-way satellite communication in Hong Kong, China. Users only need to use a China Telecom or China Telecom (Hong Kong) SIM card and activate the direct connection satellite service of their mobile phones. It is worth noting that Xiaomi 14 Ultra needs to be the version sold in mainland China, and the system version must be upgraded to V1.0.9.0. Because only the version sold in the mainland of Xiaomi Mi 14 Ultra previously supported satellite communications, other versions did not support this function in hardware. Only telecom cards are supported because Tiantong satellite is operated by China Telecom. It is reported that

If necessary, try to install the source code and carefully check the compilation log, but this requires a certain amount of Linux knowledge and experience. The key to ultimately solving the problem is to carefully check the system environment and error information, and refer to the official documents.

Operating systems supported by Oracle Database include Unix systems (such as Linux, Solaris), Windows systems (such as Windows Server, Windows 11), z/OS, and macOS, with specific requirements varying by database version and operating system. Supported platforms include x86, x86-64, ARM, SPARC, and POWER, depending on database version and compatibility. Factors such as hardware compatibility, performance, security, usability, and budget constraints should be considered when selecting an operating system.

Oracle Database CPU requirements include: support for x86 and SPARC processor types; CPU with 8 or more physical cores recommended; CPU with clock speed of 2.5 GHz or higher recommended; CPU with 32 MB or more recommended L3 cache CPU; need to support the following instruction sets: x86: SSE4.2, AVX, AVX2; SPARC: UltraSPARC III, UltraSPARC T5. In addition, factors such as hyper-threading (not supported), virtualization (caution required), operating system requirements, etc. should also be considered.

This article introduces several methods to check the OpenSSL configuration of the Debian system to help you quickly grasp the security status of the system. 1. Confirm the OpenSSL version First, verify whether OpenSSL has been installed and version information. Enter the following command in the terminal: If opensslversion is not installed, the system will prompt an error. 2. View the configuration file. The main configuration file of OpenSSL is usually located in /etc/ssl/openssl.cnf. You can use a text editor (such as nano) to view: sudonano/etc/ssl/openssl.cnf This file contains important configuration information such as key, certificate path, and encryption algorithm. 3. Utilize OPE

Reasons and solutions for the failure of nginx restart: Configuration file error: Check nginx configuration file to ensure that the syntax is correct and the instructions are valid. Open port conflict: Check whether the port is occupied, close the occupied process or change the nginx port configuration. Process is running: manually terminate or stop nginx process using service command. Missing dependencies: Install or update required nginx dependencies such as openssl, zlib, pcre. File permissions issue: Grant nginx users to read and write permissions to files and directories. Memory leak or high load: monitor memory and CPU usage of nginx processes, upgrade nginx version or reconfigure worker processes. External factors: Check for prevention
