(1) International language Once the Raspberry Pi system is installed, the "raspi-config" tool appears for the first boot, such as: (if it is not initially started, in command mode, please enter the sudo raspi-config command to bring up this interface.) If you open the desktop's LXT client under the graphical desktop, the sudo raspi-config command can also be used to bring up the tool. 1, such as , through the keyboard up and down, the blue bar,

This morning, I took an hour out of my busy schedule to experience a banana pie that was sent a few days ago. The overall experience is quite good. First brush the SD card, I use the system is Raspberry Pi raspbian into the bananapi system, making the SD card See http://www.lemaker.org/resources/9-81/raspbian_for_bananapi.html. It also officially supports lubuntu, archlinux, opensuse, Android, and other systems. See http://www.lemaker.org/resources/

On the Raspberry Pi, you can see the date and time of the system by playing the date command: Small knowledge: The Raspberry Pi does not have a battery and cannot save the time after a power outage. The Raspberry Pi is installed by default with the NTP (Network time Protocol) service to obtain the times provided by the NTP server on the Internet.

About Raspberry Pi: Raspberry Pi is a Linux-based PC equipped with a 256 MHz processor, memory, SD card and Ethernet support. It has two USB interfaces and supports HDMI and RCA output. It is reported that although the Raspberry Pi looks very mini-it only has one credit card, it can run games like thunder hammer 3: arena and play P videos. The hardware foundation

Draw a square with a side length of R and a circle with a radius of R of One-fourth (as shown), throw darts at random, and calculate the π value by calculating the proportion of darts falling in the star area and the whole area.The formula is deduced as follows:Assuming that the square's side length R is 1, then the Dart falls on any point in the Star area (x, y), and its coordinates are bound to be less than 1 of the sum of squares (x2+y2).The code is as follows:ImportRandomdefFind_pi (num_of_t
