Preface
Because I have been very interested in linux, I started an experiment with Raspberry Pi and set up a simple php server to run typecho.
However, the process is extraordinary, and almost every step is stuck. in addition, compared with WordPress, typecho has less data, which makes the process of solving the problem a little difficult.
The first is the Raspberry
40 Gpio on a Raspberry Pi is the best thing to play.They can be directly controlled by c,/c++, Python, Java and other languages.Now, let's see how to do the same thing with node. js.Before you try, install node. js, and move to: 1. Prepare the Test foldermkdir/home/pi/documents/test-gpio-demo/2. Create a file Package.j

linux applications. the reason is very simple. perl is fading out, ruby is not powerful, shell is not enough, php is not suitable, and java is not explained.
I remember that the Redhat 7 character interface installer was written in python, which was almost the first time I heard about python. it was very powerful, easy to use, and easy to modify and adjust.
