Enterprise Information Portals (EIP) have gradually been transformed from fashion to an irreplaceable business tool providing employees with a single point of access to data, tools for management of business processes and information exchange facilities. The Liferay project to be distributed under an Open Source license competes quite successfully with most commercial solutions.
Python itself is, of course, a programming language. But many people mistakenly believe that Python is the very thing that comes with most of the *nix systems and can be launched by typing “python” in the console. That is, the interpreter (a specific version thereof) is associated with the language as a whole. Just like those guys who write on Delphi. But what does it really mean?
For many years, I have been a fan of development for Windows and wrote pretty much about it to this best computer magazine ever. I switched to Mac OS and UNIX with time.

Information is currently gradually becoming “new oil” in terms of value. The only problem is that the volumes of data to be processed are growing by leaps and bounds. The sizes of files are sometimes larger than the hard drive, not to mention that RAM can’t cope, and interviewees receive increasingly scary tasks like comparing two petabyte files on the fly. But, fortunately for programmers, there is no need to make the machine choke on such amount of information, as iterators and generators can be used for threading, and there is also Python, a programming language which supports them perfectly. Would you like me to tell you about that?
Apache Tomcat is a server of web applications primarily used in commercial environment not only as an application platform, but also as a component of large projects related with providing of a web-interface. In corporate sector, security of information systems has the highest priority, while infrastructure stability ensures failure-free operation. Let us test a vaunted stability and security of UNIX daemons taking Tomcat as an example.
Since the beginning of dynamic Web development, а synchronization problem has emerged concerning a set of software programs, its versions and configurations in production and development environments. The developer of Vagrant has invented a new tool which is supposed to help solve the problem — Packer.
