WPF UI Thread Blocking Issues and Solutions
When developing desktop applications, particularly when using the Windows Presentation Foundation (WPF) framework to build rich client applications, properly handling the user interface (UI) thread is crucial for ensuring the application’s smoothness and responsiveness. The UI thread, also known as the main thread, is the core thread responsible for processing window and control events, layout calculations, and rendering the UI. Any interaction with UI elements should be executed on the UI thread; this is a fundamental principle followed by WPF and most other GUI frameworks.
Upgrading the GCC version caused program crashes: hidden issues due to code non-compliance.
In the same business code scenario, the program compiled and ran normally in a CentOS 7 environment. However, when switching to CentOS 8 and using an updated version of GCC for compilation, the program crashed. It’s worth noting that the issue only occurs in Release mode, while Debug mode does not exhibit any problems. This is the first time we’ve encountered a situation like this; after three days of investigation, we finally identified the root cause.
VMware Virtual Machine CPU Resource Usage Anomaly
Background: The business system, running in Windows version, is deployed locally and consumes approximately 5% of CPU resources. The Linux version of the business system, deployed within a VMware-installed CentOS8 environment, exhibits abnormal resource consumption. Problem Description Host Machine: Windows 10 Enterprise VMware: 17.5 Virtual Machine: CentOS8 The virtual machine resource allocation is 4C8GB, running the business system. The business system is deployed in the Linux system within the virtual machine, and the internal top command observes system resource usage.
pstack troubleshoot a hung process
In software development and operations, deadlocked processes are frequently encountered. This situation can lead to performance degradation or service unavailability. This article introduces how to use the pstack tool to troubleshoot deadlocked process issues by analyzing process stack information to identify the root cause and resolve it. Background: A child service within the risk control system experienced a deadlocked state, resulting in the unavailability of the risk control service. Due to the lack of service availability monitoring, the deadlocked process situation was not detected in a timely manner, leading to system unavailability.
Getting out for a walk is always good.
If things had gone as the family planned, I would have stuck to studying power grids honestly and diligently, without venturing into coding. Had I erased the dust from my memory, it all stemmed from a chat with my roommate near the Spring Festival, which led to a review of my experiences over the years. Chapter One The results of the gaokao (national college entrance examination) coul
C++ Function Call Latency
Designed a行情 SDK, implementing different callback function implementations, and performed an extensive test. Recently I’ve been looking into C++ function programming, where functions have become first-class citizens, flowing within the program internally – what’s the difference in performance?

leimao大佬 also did similar tests, so I borrowed their code.
