Enjoy the convenience of open source

Article Title: enjoy the convenience of open source. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Most users other than linux, and even a considerable number of linux users may not know yet. Since the emergence of the Internet, almost every change around you is caused by open-source software. When you are enjoying the innovative concepts of generation after generation, don't forget that the new experiences once and again are given by some unknown people and unknown software. Without them, today's world is completely different.
　　
　　 Email
　　
No one has heard of sendmail. Even windows hackers who have never touched linux are not familiar with this system. You must remember the vulnerability of using sendmail to retrieve password files. Yes, this is the Mail transfer program that has been developing applications on ARPANET since the advent of TCP/IP. Today, the entire Internet email transmission infrastructure is dominated by a series of open-source software such as sendmail.
　　
　　 BBS
　　
Unlike BBS on the Web, the early BBS was a product of the hacker community. Although the hackers here also include general intruders. However, it relies on open source code and contributions from some people. Through telnet and telephone lines, people can share their thoughts and codes with people with the same purpose. The BBS culture they created is still affecting the behaviors, codes, and language habits of BBS on the Web.
　　
　　 Usenet
　　
Hackers have developed Usenet. Usenet has trained a generation after generation of hackers. Even today, as Web and IM are widely used, Usenet is still the preferred source of information for learning various technologies. A large number of veteran hackers are fond of Usenet. Of course, you can access Usenet indirectly through multiple media instead of using dedicated NNTP clients.
　　
　　 IRC
　　
Almost every linux release with a certain scale now has one or more irc channels for communication between developers or users. Compared with Web forums or IM software. This open and rapid communication method is a more efficient way to share technology and obtain information. During the winter vacation last year, I went to the irc channel of fedora. The above level is very high. However, IRC is blocked in the city where the school is located.
　　
　　 Web
　　
Early Web servers and browsers are almost all open-source products. Apache and mozilla are still the best http servers and browsers in the world. I am not talking about the history of Web.
　　
　　 Socket
　　
Without the socket implemented by BSD, the development of the Internet is likely to slow down for several years. It is because there is no private BSD license agreement. It allows both individuals and companies to use its code impermanence. Do you remember to use strings to process the information output by standard FTP programs in windows? Without the BSD license agreement, it is impossible for Microsoft to quickly add network support to the system, and of course it is impossible to bind IE.
　　
　　 BitTorrent
　　
What makes your computer full of the latest and best movies? It is an open-source software and a young man who loves the open-source business. Although you have used a large number of private BT clients written in C ++ today. But remember that BT was written in python. Python is also an open-source community language.
　　
　　 Wiki
　　
Compared with the great idea of Wiki, it does not get the attention it deserves. Wiki expands the concept that open thinking is limited to software. Imagine that the materials you want to obtain in the future can be found through various open document protocols, and you will understand the meaning of the materials. This meaning even exceeds the open source of software. Wiki also proves to the world that culture is not limited to specific forms, and Linux is not the only form of open thinking. People are willing to share and pursue the virtues of progress.
　　
I mentioned above only the software that plays an important role in the development and innovation of the entire Internet. Through the above introduction, you can learn how you can unconsciously enjoy the convenience brought by this open-source software. Without open-source software, this will no longer exist. Countless open-source projects, large and small, are quietly making contributions behind the scenes. Shared libraries such as glib and openssl make the advent of epoch software possible. Some people complain that the dependencies between various types of software in Linux are too complex. In fact, this dependency exactly represents the spirit of sharing soft software developers never let others waste a little time, and never do a little repetitive work. Moreover, this spirit of sharing and collaboration can help people better understand how to bring the role of the Internet to its limit.
　　
These inventions created on the Internet reflect the strong desire to communicate and communicate in the subconscious. People are eager to use the bandwidth of every byte of the Internet to express and obtain information. From the early development of Linux on the network, the spread of GNU software on the network, to the network-based distribution of various open-source systems. Apt/yum software repository, BSD ports and gentoo ...... Updates to azureus and even their own software are distributed using the BT protocol. We have no reason not to believe that the best idea of Internet applications will always come from those who have the most communication and sharing desires. We also have reason to believe that open source code is not only a free software experience, but also a more advanced online thinking and communication experience.
　　
If you are a person who is willing to share, like to communicate, and is not afraid of challenges, you have no reason not to use open source software. Because a group of people are waiting for you to use your smart power to change the world with them.
