The book author Trent Liu (Liu Chuán) engaged in the operation and maintenance of Linux technology industry, and with Red Hat engineer in 2012 RHCE 6 version of the certificate, in early 2015 they were given Red Hat engineers RHCE 7 version of the certificate and Red Hat Certified Architect RHCA top certificate.
Learning is a chore:
Mr. Kazuo Inamori segment has been an inspiration to me, now turn to the book you're reading in the "living law" in:
"Work so-so, just looking at the interest in the game and happy, at best, can only obtain temporary pleasure, never tasted gush from the heart of surprise and joy, but the joy from work is not as sweet as - into his mouth it is full of sweetness, but need elbow grease from leaking and hard, so when we attentively, diligently to overcome the sense of achievement after the hardships, there is no such kind of joy can be compared. "
"Not to mention human life, work occupies a large proportion, if not, work to get a sense of fulfillment from work, then even find happiness from somewhere else, and ultimately we will still feel the emptiness and regret."
Share the spirit of open source: open source product not only has a low risk, good quality, low cost and more transparent four major advantages, as well as a free copy, use free, toll free, free to modify, create derivative works freely Five Freedoms.
Linux development history:
In the early 1970s, UNIX system is open source and free. But in 1979, AT & T announced plans for a commercial UNIX system, along with open-source software industry is transformed into a type of software copyright industry, the source code is treated as trade secrets, patents become products that people can no longer enjoy freedom Technological Achievements.
So in 1984, Richard Stallman in the face of such a closed environment creation software, launched the GNU open source program and developed a well-known GPL license agreement. In 1987, GNU plan was a major breakthrough -gcc compiler release, which allows programmers to write their own open source software based on the compiler. Following this, in October 1991, University of Helsinki, Finland, Linus Torvalds students to write an operating system called Linux's. The system code because of its high quality and based on open-source characteristics of the GNU GPL license agreement, quickly supported by the GNU Project and a large number of hacker programmers. Then Linux system will enter the stage of development in full swing.
In January 1994, Bob Young on the basis of the above Linux kernel, integrates a number of source code and software, has released Red Hat system and began selling technical services, which further promoted the popularity of Linux systems. After 1998, with continued hot GNU Linux open-source programs and systems to IBM and Intel, led by a number of IT giants began to vigorously promote the development of open source software. By the end of 2017, the Linux kernel has been developed to version 4.13, and there are hundreds of versions of the Linux system as many, but they still have to use Linus Torvalds to develop and maintain the Linux kernel. RedHat company has become the open source Linux system and industry leading companies.
Common Linux system:
Red Hat Enterprise System (RedHatEnterpriseLinux, RHEL.)
Community Enterprise Operating System (Community Enterprise Operating System, CentOS) 2014 years was acquired redhat
Released by Red Hat Fedora desktop system package (currently limited to the desktop version).
openSUSE from Germany, a well-known Linux system, has a good reputation and market share on a global scale.
Gentoo is highly customized, complex operation, and therefore suitable for experienced personnel. Readers can try the system after learning this postscript.
Debian stability, strong security, provide free basic support, we can well support a variety of hardware architectures, and provided nearly 100,000 different open source software, with a high degree of recognition and usage abroad.
Ubuntu is a Debian derived from the operating system, with strong compatibility of the new hardware. Ubuntu and Fedora are extremely good Linux desktop systems, but can also be used Ubuntu server space.
