Information technology today is one of the most dynamic areas. The demanded set of knowledge and skills of a modern specialist, be it a developer, tester, system administrator, technical support or information security employee, reminds a fairy tale about Alice in Looking Glass, in which “you have to run as fast as you can to stay in the same place, to get to another place, you need to run twice as fast. "
Unfortunately, this situation leads to a gap between the program of training specialists in the academic environment and the technologies that they will have to face in a modern Internet company. Information Technology Courses (
CIT ) do not pretend to fill this gap immediately, but are intended to be a meeting place and a dialogue for young and experienced industry professionals.

The fourth CIT, which was held in October-November 2013, included the following lectures, the videos of which we publish:
')
- Building virtual stands - which virtualization systems can be used to study operating systems and network services, an overview of popular solutions.
- Launch Linux: how to study systems - recommendations on how to use a systems approach to mastering Linux using the example of “engineering” distributions, such as Linux From Scratch, Gentoo, ArchLinux.
- IPv6 - familiarity with the sixth version of the IP protocol and an explanation of why the transition to it is inevitable.
- PKI is a public key infrastructure and disadvantages of its current use.
- Cgroups is a Linux mechanism for grouping processes and managing resource consumption by the example of using banner advertising in systems.
- Python for the system administrator is a programming language that is increasingly used in system administration.
- Information security - why information security does not exist, what it really is, and why this topic is particularly relevant at the moment.
Fourth-year CIT lectures were conducted by Yandex employees: Vladimir Ivanov, Anton Karpov, Dmitry Kulikovsky, Andrey Grigoriev, and Viktor Ashik. In addition to them, full-time lecturers could chat with Yandex system administrators and learn about their work "first-hand." The lectures were accompanied by homework assignments that were formulated as programming tasks and checked by the Yandex.Contest Olympiad Programming System.
Following the results of the course, more than 10 people in the near future will begin an internship at the Yandex operation department under the guidance of system administrators and try themselves in solving practical problems.
