Windows Linux Mac

When I had my first computer in 8 years old, it was running the operation system which is called Windows. It wasmy first time that I had played the computer.
After that, I learn more about thecompany which is called Microsoft. I have been used Windows operation systemsince then. And this year is my 17th years of the time when I use Windows. The friendly design of GUI allows me to interact with the
computer conveniently. However, Ihave experienced a terrible nightmare when I was in senior high school. Forthat time, the behavior of the software is so bad that I am so afraid toinstall any software from the Internet. The problem is that the installation
ofthe software didn't illustrate me that it has accompanied with another software without any promption. After I installed, the pop window annoyed me and it was a horrible experience at that time.
When I was in college, I gradually used VMware to learn another two kinds of operation system. The first one is Linux. Linux is open source software which everyone can read, write, commit and even change the source code. After I studied the
course of Linux Kernel, I have acknowledged Linux is the best operation system. It allows every programmer to participate in. I study Python in Linux. As matter of fact, the reason why Iinstall the Linux again and again for the reason that I often change the
version of the python and change the soft link of python. This misbehavior crashes the system.
Now, I am using Mac. It give me astrong impression of its beautiful design of UI. I don’t think Mac is betterthan Windows, and its kernel is based on Linux. That often makes me laugh at it.
In short, I gradually spend more time on Linux and less on Windows. So many software, Python, Perl, R, forinstance, is more flexible when they run on Linux. A friend said to me, Linuxis more productivity than Windows. I was doubt these words
at that time, but now I understand what he said.
