we have already used the official image to set up the Raspberry Pi development environment, it can be said to be able to use the application, but if the official kernel has some features that do not meet our needs or need to partially crop the kernel, then we need to crop the Raspberry
after the first two steps our Raspberry Pi has worked normally, but before actually using it to develop some column configuration and software installation, so that the development will be handy, below we introduce the common software and services1. Configuration options:The first time a Raspberry
/folder, create a smbpasswd file with the following command:sudo touch/etc/samba/smbpasswdAdd a user named AAA to Samba: sudo smbpasswd-a AAAWill let you enter the password, you set one, set up will display: Added user AAATo get here, and then open the network next door, enter the user name and password just set, then go in, will find a TMP folder, you can freely read and write data in this folder, such as the film, test films, songs, songs, and so on, anyway you understand.

For those who already have a certain Linux Foundation, Raspberry Pi should be very simple and natural to learn. In their eyes, Raspberry Pi is a simple, cartoon version of Linux. However, it is not easy for me to compile, compile, and run a simple program for a person or beginner who is familiar with the Microsoft tech

It is important that you do not need to configure any environment for development (the Linux system provides its own interpreter + vi editing ). I have a hard time learning python. I use PyRaspberry Pi Documentation.
PYTHON
Python is a wonderful and powerful programming language that's easy to use (easy to read and
logic.
Yesterday my wife read the Rpi.gpio document, one hours and dozens of lines of code can be achieved by the Raspberry Pi car through the infrared detector tracking operation. It's something that no other language can do or that's hard to do.

Some cameras will have an error when executing this command, at least if you do not return to the command prompt at the end, and display "starting

You may have read my previous introduction to snappy Ubuntu. is not eager to get a snappy system to their own development Board AH. In this article today, we will show you how to assemble your own Raspberry Pi snappy Ubuntu system.
Final version:
We can buy the development version of the
small Raspberry Pi when thin client. In the far-off area of the school is not enough, you can prepare a Raspberry Pi for each child, install Linux, write programs, also can be thin client connected to X server or VNC server and FreeNX server, may want to buy another HDMITo DVI. 4.
