Quite often claim, raised at OpenSource solutions, is the question of its safety. Argues that, since the software is available, then everyone can go inside and catch the error, which would enable him to break such as web server operated by the running program is flawed. How much truth is in these statements? It actually creates openness sources such options as described above. However, this is an asset, not a defect! Why? Answer to this question, the software should be compared with closed software, whose code is publicly available: |

And here we come to the heart of the matter. Much of the software continue to be supplied without source code. When buying in a shop computer game or word processing program to receive a billing program. We can run it, use it to profit from its assistance to life ... and at the law in most of our end. If included in the license agreement for this program, easily perceive in it a prohibition of the dissemination or making any modifications to the plan without modification of source code, but rather difficult, it is impossible. |

A computer program, sometimes also called an application or executable file, from the viewpoint of a user's computer files or more, as for example in a text editor. However, this is a file that is specific enough that after the opening will not access any data at all and just run the program. On your computer's hard drive containing a document both commercial as well as a spreadsheet program or the price list will be saved in the form of one or more files. It is not among them almost no difference [of course, beyond the content and the fact that you can run programs, and other files] - programs and other files can I send the same e-mail, delete, copy, and rename. This is of course an impact on their operation and never change their names or their disposal - but from the point of view of this article, program files and files of documents are in some respects very similar to each other. |

Myth, which unfortunately is often duplicated in the media, it is feared that the opening of the code will leak outside the company's confidential data. "If we just look ..." you should be aware at this point important distinction: transparency code, or even publicity the way in which they were saved data [ie. encryption algorithms] has nothing to do with the transparency of the data. From a mathematical point of view, even knowing how the data was encrypted, we can not read confidential data, if we do not have the keys needed to read them. And if we have the key or not, has nothing to do with the openness or closure of the software, and only from properly conducted the company's security policy - access to sensitive data should be protected under similar conditions as access to corporate cash, and not by concealing the source program. |

Linux, like Unix's father, can be operated only from the command line. All graphical environment (KDE, Gnome) and managers overlay windows are only on the console. This action is a deliberate, since the work from the command line allows quick and easy system administration, is ergonomic for the system (there is no undue burden on video), and enables easy automation of operations (there is no need to create scripts for the graphic interface). It is therefore expected that there should be no long here as in the evolution of Windows, which is the elimination of text to graphics. The basic message - bash shell |
