Many companies, including Google and coverity, now like test-driven development ). It works by writingProgramWrite the automated unit test at the same time ). InCodeAfter modification, these tests can be run in batches to avoid unexpected errors.
This is not a bad idea. I also used many tests in Kent's compiler course. They are indispensable in Compiler development. The compiler is an extre
The Python code has the lowest density of bugs, just 0.005 per thousand lines of code, according to the Coverity company, which provides development testing services. Industry-accepted standards are 1 per thousand lines of code defects, code defect density less than 1.0, which is considered high-quality code.
According to the 2012 Open source Code Scan report, the average defect density of open source code is 0.69, while Python is 0.005.

source, through the detection of laser and detected by the interaction of optical signals to complete the remote sensing measurement. LiDAR can be used to generate high-precision maps, and for high-definition maps to complete the positioning of mobile vehicles, as well as to meet the requirements of obstacle avoidance. Taking the Velodyne 64-beam LiDAR as an example, it can perform 10Hz rotations and can reach 1.3 million readings per second.

When laser or sonar distance sensors are used to construct a two-dimensional map of a small static environment, the slam problem is considered to be solved. However, for dynamic, complex and large-scale environments, using vision as the only external sensor, SLAM is an active research area.The first part is the introductionThe autonomous navigation problem of mobile robot is divided into three main aspects: location, map and path planning.Positioning

You can see that the ITBC user that you just created is already in the user table. The Host field represents the hosts that are logged on, their values can be IP, or the host name is available, and changing the value of the host field to% means that the ITBC user can log on to the MySQL server on any client machine, and it is recommended that you set it to% at development time.Update user Set host = '% ' where user = ' ITB
