Introduction to Arm
Arm processors are ubiquitous.
Mobile phones, personal computers, televisions, or cars. In a total shipment of about 3 billion microprocessors, the x86 architecture occupies a very small position (but still
Understanding the Differences Between Linux and RTOS
Do you know which operating system is the most popular in the world? It is Linux! It generally runs on servers and supercomputers, and the millions of servers behind the websites we access daily are likely running Linux. In this article, we will learn what Linux is, where it comes from, commonly used Linux knowledge, and the
Upgraded Matrix Clock Open Source Release!
Time flies, and another year has passed in the blink of an eye. I wonder if everyone still remembers that last year around this time I open-sourced the first matrix WiFi clock. Subsequently, I released a shorter upgraded version as a product in my Taobao store, and many friends purchased it to support me, for which I am very grateful. However, later on, due to a busy work schedule, I had no time to produce it, so I took

Understanding the Role of Module Power Supplies in Circuits
Advantages of Module Power Supplies, Applications of Module Power Supplies, Installation and Maintenance of Module Power Supplies
1. Overview
The design of today's power supply systems poses significant challenges for electronic designers. They must utilize limited resources and space to design flexible, efficient, reliable, and competitive power supply systems in a short time. Module power supplies (or power modules) are currently the best choice for designers. Replacing discrete component designs with
2017 Black Hat Conference Arsenal Tool List
From July 23 to 31, the most popular top information conference in the security circle, the Black Hat Conference (23-28) and the DEFCON Conference (28-31) kicked off in Las Vegas, USA.
Every year at this time, tens of thousands of hackers gather in Las Vegas. Don't think that hackers are gamblers; they are all here for the famous "two conferences" in the security circle. It can be said that they have no interest in gambling skills, but are obsessed with "security
Raspberry Pi Pico: The $4 MCU Revolution
Today, the Raspberry Pi Foundation launched its first microcontroller-level product: the Raspberry Pi Pico, built on a brand new RP2040 chip, priced at just $4.
If you have used Arduino or some development boards that support MicroPython, you should be familiar with this type of microcontroller product (MCU). The ultra-low power consumption, extremely low I/O latency, low price, and simple control methods make the Raspberry

First, you need (maybe more than one) a broken HoloLens
About five or six years ago, a friend lent me a first-generation HoloLens, and the experience is still unforgettable.
HoloLens：
HoloLens is a mixed reality headset developed by Microsoft. The glasses track your movement and gaze, generating appropriate virtual objects projected into your eyes. Because the device knows your position, you can interact with virtual 3D objects
