How to choose the sensors in the mainstream
At the end of the 16th century, Galileo built a device to display the temperature change. Using the principle of air contraction in the container, he observed the height of the water column to judge the temperature change. The thermometer we know now was invented by Santorio in 1612, but at that time he only […]

It is the most commonly used type in Linux file system, and it is outstanding in speed and CPU utilization. Ext2 […]
Intel to launch new analog chip Loihi
Intel has launched a representative chip for neuromimetic computing, which is simply to simulate human brain behavior through digital circuits. It can be said that this chip with autonomous learning function is expected to bring more possibilities to the AI industry. This chip is code named “Loihi”. In fact, this chip has been exposed in […]
What are the advantages of PIC microcontroller over other Microcontrollers
I have been engaged in the development of single-chip application system for many years, and I have used many types of PIC single-chip computers. I feel that PIC single-chip computers are really convenient to use: 1. PIC microcontroller uses a simplified instruction set, only 35 instructions are needed for mid-range products, the threshold for entry […]
The exposure performance of Ruilong 3 3250c reaches the standard of Xiaolong 730g
Yesterday, we reported that the sharp dragon 7 3700c suddenly appeared in Geek bench. Now, the sharp Dragon 3 3250c of the same series also appears on the running website. According to the geekbench page, the sharp Dragon 3 3250c is a dual core four thread processor with a basic frequency of 2.6GHz, a three-level […]
Will SMR hard disk and PMR hard disk avoid SMR in the future?
Like the QLC flash memory in SSD hard disk, the SMR hard disk in HDD Hard disk is also disliked, because it is essentially a product that manufacturers like, but consumers have to bear the cost. Compared with the traditional PMR hard disk, the performance and reliability problems. What is SMR technology? In short, SMR […]
