Rust 1.38 has been released, and the contents of the stable version 1.38.0 are as follows: Pipelined Compilation If you want to compile a crate, the compiler does not need to fully build dependencies; it only requires their “metadata” (i.e., types, dependencies, exported lists), which is generated early in the compilation process. Starting from Rust … Read more
Setting breakpoints is a very effective way to debug programs online. Combined with step-by-step debugging, it allows for quick problem identification. However, sometimes manually setting breakpoints can be inconvenient. For example, if you want to stop at the Nth iteration of a loop, you would have to keep clicking step run until the loop reaches … Read more
In the paper industry, a reliable automation control system can significantly enhance production efficiency and product quality. This article will detail the core technical points of paper machine control, from hardware selection to program design. 1. Hardware Configuration Plan 1. PLC Selection Explanation It is recommended to use Siemens S7-1500 series PLC for the paper … Read more
Programming Recommendations 1. When a PLC and a host computer (or touch screen) form a monitoring system, it is often necessary to have control modes such as “Manual” and “Automatic” on the screen (generally, only one can be active at a time). In the program, you can use the “MOV” instruction. For example: when “Manual” … Read more
Introduction This article introduces how front-end engineers can use HTTP proxies for debugging, going beyond the limitations of DevTools. Today’s front-end reading is shared by @huli. The main content starts here~~ As a front-end engineer who deals with web pages daily, it is quite reasonable to be familiar with the use of DevTools. Whenever there … Read more
“This article details the process of hardware disassembly, firmware extraction, debugging, and modification of the Xbox One controller. The author explores the internal structure by disassembling the controller, identifies the SWD interface, and uses the OpenOCD tool for hardware debugging. The article also explains how SWD works, how to use OpenOCD for firmware extraction and … Read more
OCD stands forOn-Chip Debugger, which is on-chip debugging. OpenOCD is an open-source JTAG debugging tool that operates as follows:The following diagram shows a physical connection, where the debugging target is theIntel Galileo Board, and the hardware box is the Flyswatter. The small board labeled 4 is theARM-JTAG-20-10 Adapter:When starting OpenOCD, a configuration file is passed … Read more
Hello everyone, welcome to Lixin Embedded. In Linux development, core dumps are powerful tools for debugging program crashes. However, on devices with limited storage space, core dump files that can be several megabytes in size can take up a lot of space. In the previous article, we discussed the principles and generation mechanisms of core … Read more
Disk I/O performance is a core aspect of optimizing Linux system performance, especially in high-load scenarios such as database servers, virtualization environments, or big data processing platforms. Disk I/O bottlenecks can lead to slow system responses or even service interruptions. Monitoring and debugging disk I/O performance not only helps administrators quickly locate issues but also … Read more
