Windows treats the hardware clock as Local time ). Because the time processing method is different, Windows recognizes the Local time no matter how many times it is restarted, and the time will not change. When we restart from Ubuntu to Windows, the hardware clock has been regarded as UTC by Ubuntu, and Windows forcibly converts it to Local time, which leads to a time difference.
How can I solve the problem of time synchronization between Ubuntu and Windows?
To avoid time synchronization betwee

Update-rc.d commands in Ubuntu or Debian systems are scripts used to update system startup items. The links of these scripts are located in the/etc/rcN. d/directory, and the corresponding scripts are located in the/etc/init. d/directory. Before learning about update-rc.d commands, you need to know the main startup steps for Linux and the r

Recently, GPRS communication has been implemented, but the GPRS module (q2403a) on hand is a five-line serial port (rxd, txd, Gnd, RCS, CTS), and the boss is reluctant to buy new modules. Therefore, you need to change the debug serial port COM1 to a common serial port (this is also the 5-line serial port on the flying Development Board ). I found some information on the Internet and

Linux boot process analysis and grub boot program
Boot is simple for each of us. But what process does it take to start the entire boot process?
Generally, the Linux boot process follows the following steps:
1. Load BIOS hardware information, perform self-check, and obtain the first startup device according to the settings.
2. read and execute the Boot Loader (grub) of the MBR in the startup device)
3. When bootloader loads the kernel, the kernel detects the hardware and loads the driver.
