In the previous article “Distributed application full-link tracking implementation”, several implementation methods of distributed application full-link tracking were introduced. This article will focus on the full-link implementation based on Skywalking, including the overall architecture and basic concepts and principles of Skywalking. Skywalking environment deployment, SpringBoot and Python integrated Skywalking monitoring implementation, etc. 1. Basic introduction […]

Qt inherits QAbstractListModel to implement a custom ListModel
1. Introduction QAbstractListModel is an abstract class in the Qt framework, used to implement the data model and used to display and edit list data in Qt’s view components. Similar to QAbstractTableModel, it is also an abstract class that provides some basic interfaces and default implementations to easily create customized list data models. The main […]
Abstract black box vulnerability scanning and risk technology assessment methodology
As a technical boy who has long struggled with automated detection/mining solutions for various vulnerabilities, we will encounter many problems when writing a “scanner”, such as How to ensure that your payload is harmless? How to balance the contradictory relationship between outsourcing and “detection rate”? How to trigger WAF as little as possible? How to […]
Unexpected key(s) in state_dict: “module.backbone.bn1.num_batches_tracked“
Unexpected key(s) in state_dict: “module.backbone.bn1.num_batches_tracked” When using PyTorch for deep learning model training and inference, we often use ??state_dict?? to save and load model parameters. However, sometimes when we try to load the saved state_dict, we may encounter the error “Unexpected key(s) in state_dict” and indicate the error key name. This article explains the causes […]
C++ Standard Templates (STL) – Type Support (type attributes, is_abstract, is_signed, is_unsigned)
Type attributes A type attribute defines a compile-time template-based structure for querying or modifying the properties of a type. Attempting to specialize a template defined in the header results in undefined behavior, except that std::common_type can be specialized as described. Templates defined in the header file may be instantiated with incomplete types unless otherwise specified, […]

Microcontroller Project: Design of Sun Tracking System Based on Microcontroller
Summary According to the relative motion rules of the sun and the earth and the motion orbit of the sun relative to the earth in the equatorial coordinate system and the horizon coordinate system, and based on the application value, an open-loop tracking control strategy using a stepper motor as the driving mechanism is proposed, […]
Algorithms and Data Structures-Backtracking Algorithms
Article directory How to understand “backtracking algorithm”? Classic applications of two backtracking algorithms 0-1 backpack regular expression How to understand “backtracking algorithm”? Generally speaking, backtracking algorithms are often used in problems such as “search”. However, the search mentioned here does not refer in a narrow sense to the graph search algorithm we talked about before, […]
