In the software research and development industry, programmers over the age of 40 are called "old programmers", and the current fire of blockchain is called "classical Internet old programmers". What happened to all those 40-plus programmers who were told "it's time to retire" by millennials? Don't worry, Lian Po is old and edible. Most of the developers I know have made the transition to management, but also...

In this paper, an Arduino Uno development board is used to connect the MPU9250 sensor, and the sensor acceleration and gyroscope data are obtained. Arduino Uno MPU9250 Connection mode MPU9250 Arduino 3.3V

1. First of all, press Linux on the computer and try to use the domestic mirror station. Otherwise the next JDK and Hadoop will be very, very slow. 2. Don't be lazy. JPS can not be found after installing openJDK in one go. Install oraclejdk. 3. In the new version of hadoop, the local port number is 9870 instead of 50070. 4. Restart...

Because manufacturers of IoT devices often assume that other devices on the same network are reliable, the default for these IoT devices is to use unencrypted HTTP services and rely on malicious commands sent from browsers that allow hackers to launch DNS rebinding attacks. Armis, which works to eliminate blind spots in IoT security, noted last week that an estimated 496 million IoT devices are exposed to DNS rebinding...

1. Background Introduction With the development of Internet of Things technology, real-time video analysis technology has been applied in various fields of intelligent Internet of things, such as intelligent retail, intelligent factory, intelligent monitoring, etc. If video is compared to the eyes of crop Internet, then real-time video analysis technology is the brain of Internet of Things. At present, video analysis based on deep learning and computer vision is the most common way. In a very common scenario in iot technology -...

** Introduction ** I believe that many people involved in robot human-computer interaction interface development will contact or use Qt. There are also qT_ROS use solutions on ROS wiki, but most of the interfaces are based on UI files, but sometimes this does not meet our needs.

With the continuous progress of software, software and data processing capabilities, the capabilities of unmanned flight platforms have also been rapidly improved, and remarkable progress has been made in miniaturization, long endurance, intelligence (load capacity + autonomous flight), clustering and other directions. For unmanned aerial vehicles to perform more difficult tasks, their wireless data

For the first time since 2015, the market for iot platforms did not grow. The study found that the number of platforms known as the Internet of Things doubled from 2015 to 2019, increasing from 260 to 620. However, since 2019, the figure has been slightly lower

Smart city is an important embodiment of human entering into knowledge civilization. As an important part of smart city, unmanned driving has been one of the new value heights for more and more enterprises in recent years, including BAT, a Chinese Internet giant. September 24, 2018, Hangzhou Cloud Conference "Artificial Intelligence Summit", Alibaba released the first L4 car road collaborative new energy intelligent logistics vehicle. Unmanned driving...
