Logging in Spring Boot can be optimized to enhance system throughput by adjusting logging strategies. This analysis uses Log4j2 integration as an example to explain how logging operates within the Spring Boot framework. The principles are similar for Logback, making it easy to transition between log...

Resource configuration is the foundational step in Flink performance tuning. Adequate resource allocation correlates directly with throughput capabilities. When submitting applications via YARN in per-job mode, resources are defined through command-line arguments or configuration files. Since Flink...
List Comprehensions List comprehensions offer a compact and readable way to construct sequences. Instead of initializing an empty list and appending elements in a loop, you express the entire transformation in a single line. For example, generating squares of integers from 0 to 9: squares = [] for n...
Project Overviwe Main MCU: STM32F429IGTX, SPI slave device: W25Q128 NOR Flash Expected Behavior After development board reset, flash_id ok is printed over UART. When the KEY0 button is pressed, the string flash test is written to address 0 of W25Q128, then read back and printed to the serial console...
