1.How Obstacle Avoidance works 1.1 Penalty Clause Obstacle avoidance is implemented as part of overall trajectory optimization. Obviously, optimization involves finding the minimum cost solution (trajectory) to a specified cost function (objective function). Simply put: if a planned (future) pose violates the desired separation from obstacles, then the cost of the cost function must increase. […]

MultiOTPDocker installs MultiOTP to make Windows login more secure (MFA)
Preface In the current digital age, cybersecurity has become a very important topic. As more people and organizations rely on computer systems to do their jobs and store sensitive information, keeping authentication secure has become critical. Two-factor authentication (2FA) is a powerful security measure that adds another layer of protection beyond the traditional username and […]
hotplug event processing of modesetting_drv
uevent mechanism There are two ways for uevent to report events to user space: 1. Directly call executable programs or scripts in user space through the kmod module 2. Pass events from kernel space to user space through the netlink communication mechanism About hotplug interface implementation and calling in modesetting_drv void drmmode_uevent_init(ScrnInfoPtr scrn, drmmode_ptr drmmode) […]
How to build an OTP verification system using Python?
Even if your password is stolen, the OTP verification system acts as a key element of security. It eliminates the need to remember passwords, acts as an extra layer of security, and reduces the risk of phishing. You might as well learn to use Python to build an OTP verification system. It will send an […]
Use Microchip SAM9X60 OTP to store the MAC address and serial number of the board
1. Introduction The SAM9X60 processor has part of the OTP (One Time Programming) Aera that can be used to store user data. In this way, we can write the board MAC Address and SN serial number to the fixed OTP User Area. ? ?Why use the OTP area to store the MAC address and serial […]
