All operating systems have a philosophy. And, the philosophy of an operating system matters. What is the Linux philosophy and how does it affect the community? How has it changed software development for the ages?

Whether we know it or not, most of us have some sort of philosophy of life. It may be as simple as, “Be kind to others,” or it might be a very complex life philosophy.

Many companies have some sort of philosophy as well. They may be unwritten or well-documented. When I worked at IBM, from 1974 through 1995, the IBM philosophy was well-documented and strongly ingrained in the culture. IBM’s philosophy covered its business practices and how employees, customers, and suppliers were to be treated. The IBM prime directive, as it were, was to treat everyone fairly, with respect and dignity.

Whenever I setup a Linux VPS, the first thing I do is install a firewall. I have noticed an increase in attacks on my servers, especially from China. I use
Config Server Firewall (CFG) and Login Failure deamon (LFD) because they are easy to set up and provide additional features like suspicious file reporting and system monitoring.

Defining Software Defined Networking: Part 1

December 1, 2014

Editor’s Note: Over the next several weeks we will run a seven-part series about software defined networking (SDN). The stories serve as education resources and as a way to help better understand what SDN means to people developing and managing new stack infrastructures.

Thomas S. Kuhn, in his highly-influential work ‘The Structure of Scientific Revolutions’, defines the term paradigm as “universally recognized scientific achievements that, for a time, provide model problems and solutions for a community of researchers. Going by this, categorizing Software Defined Networking (SDN) as a “new networking paradigm’ may not be an overstatement. Referring again to Kuhn’s words, SDN is also “sufficiently open-ended to leave all sorts of problems for the redefined group of practitioners to resolve”.

SDN has been defined by different researchers in different terms, and the one which is more general and inclusive one is provided by Brandon Heller [1] is as follows:

“SDN is about refactoring of the relationship between network devices and the software that controls them.”
