Five tips for using Volume Shadow Copy Service to attack domain controllers
Click the star toreceive the latest tweets instantly In Microsoft Active Directory (Active Directory), all data is saved in ntds.dit. NTDS.DIT is a binary file. It exists on the domain controller %SystemRoot%\ tds\ TDS.DIT. ntds.dit includes but is not limited to Username, Hash, Group, GPP, OU and other Active Directory related information. Like the SAM […]
Active buzzer music score writing based on various types of microcontrollers (stm32 as an example) —- buzzer plays music
1. What is an active buzzer Active buzzer: The fundamental difference between active buzzers and passive buzzers is that the products have different requirements for input signals; the ideal signal for active buzzers to work is DC, usually marked as VDC, VDD, etc. Because there is a simple oscillation circuit inside the buzzer, it can […]
Moveit’s Low Level Controllers
Low Level Controllers MoveIt typically publishes motion commands from the manipulator to the joint trajectory controller. This tutorial assumes using MoveGroup to control the robot, rather than MoveItCpp or MoveIt Servo. The minimum setup is as follows: A YAML configuration file. We recommend naming this moveit_controllers.yaml to “tell” moveit which controllers are available, which joints […]

[Spring Practice – Building Spring Web Applications] 1.7 Writing basic controllers
In Spring MVC, controllers are just classes with @RequestMapping annotations added to their methods. This annotation declares the requests they want to handle. Assume that the controller class handles requests for “/” and renders the home page of the application. The HomeController shown in Listing 5.3 is probably the simplest Spring MVC controller class. Listing […]
“MicroPython implements I2S support on microcontrollers: Detailed guide with complete Python example code
Part 1: Introduction to MicroPython and Microcontrollers 1. Introduction to MicroPython MicroPython is a streamlined, efficient, and fast implementation of Python 3, designed for microcontrollers and restricted environments. Compared to traditional Python, MicroPython is optimized to run on resource-constrained devices, meaning it can run on devices with only a few tens of KB of RAM […]
A simple understanding of tinkphp routing, controllers, and requests
Routing Route mode Routing is divided into three modes, 1. Normal mode 2. Mixed mode 3. Forced mode. In normal mode, the definition of routing rules does not distinguish between request methods (GET, POST, etc.). By default, routing rules can be accessed using the GET method. In mixed mode, routing rules are matched based on […]

One annotation to overturn all Controllers
1. Overview In daily development, the most tedious thing is writing Controller. Many companies have formulated specifications: Controller cannot have any business logic and mainly completes parameter parsing and result conversion. However, looking at the project source code, you will find that there is a lot of logic in the Controller that should not exist. […]
