It measures the distance between the sensor and an object by emitting ultrasonic pulses and receiving reflected signals, and is used to detect the presence of objects. It has widespread applications in modern … Read more
Welcome to the series of articles “Introduction to ARM Assembly Programming.” This series is designed to lay the groundwork for the upcoming “ARM Exploit Development Tutorial” (in progress). Before we dive into writing shellcode and constructing ROP chains using ARM assembly, we need to first grasp some fundamental knowledge about ARM assembly. We will cover … Read more

Last night, while going out for dinner, I stumbled upon this: This must be the so-called “shared power bank” right? I don’t know how you feel about it, but this thing has been all over my feed in the past few days… Shared bikes, another member of the “sharing family,” have not been doing well … Read more
The Raspberry Pi 400 is a new product launched by the Raspberry Pi Foundation in the fourth quarter of 2020. Unlike previous products that were just a credit card-sized bare board, the Raspberry Pi 400 is a compact keyboard. The product is based on the Raspberry Pi 4B with relevant improvements. The Pi 400’s motherboard … Read more
The origin of this project stems from a discussion about the RP2040 MCU (the first microcontroller from Raspberry Pi). At the time, we were discussing how to build a simple desktop/graphical user interface for the RP2040 MCU, and I casually mentioned, “Why not just run some old operating systems?” After saying that, I suddenly thought … Read more
