Help David on his research

My favorite memory in high school is that I helped my AP physics teacher David in his research. After the end of the semester 1, David invited me to help him make a GUI program for controlling wave generators in order to generate a suitable wave to bring the laser to a stable state. I accepted his invitation and went to his lab on a Sunday.

On that day, David and I studied the application programming interface of the generator and planned how to design the program. We have met a lot of problem, but finally, we completed the GUI program using the Python language. Although the output wave still does not achieve high stability of the laser that the research needs, but it is the most memorable experience after I came to high school: to achieve the goal with David and try to solve the problems, and it is meaningful. So, this was my favorite memory from my first year in senior high school.

Ubuntu 安装 OpenVPN


希望通过自己的智能手机或者笔记本经由非受信网络(例如旅馆或者咖啡厅WiFi)安全访问互联网?虚拟专有网络 (VPN)无疑是最理想的解决方案。流量会首先被引导至VPN服务器,而后再前往目的地。



$ sudo wget -O && bash

或者下载 (openvpn-install) 然后执行

$ sudo bash

安装完成后,会在当前目录生成 .ovpn 文件,将这个文件从服务器中下载。在客户端程序中导入这个文件。
