OpenBSD acquired Ports framework from FreeBSD many years ago, and since then those frameworks diversed very much. Current OpenBSD Ports infrastructure makes it possible to have many up-to-date ports, including "heavy" ones like GNOME, LibreOffice and KDE, by relatively few number active maintainers. This talk is about features of current OpenBSD ports system: bulk package builds, package signing and updating, manual library versions handling, modules framework and other stuff.

Report describes some Linux kernel subsystems which can be used to create a high-performance data storage. Well-known instruments of storage management (RAID and LVM) are explained as far as cutting-edge technologies for multi-level caching and data tiering. Also, kernel-mode virtual target device for remote access to data storage from other hosts is reviewed.

The work includes implementation and extraction algorithms capabilities test, without any additional data (starting position, the number of bits used, gap between the amount of data encoded) information from encoded files (mostly images). The software is written using OpenMP standard, which allowed them to run on parallel computers. Performance tests were carried out on computers, Blue Gene/P, Blue Gene/Q and the system consisting of four AMD Opteron 6272. Source code is available under GNU GPL v3 license and are available in a repository OLib.

Many people participated in the SETI@Home project, which was launched almost 15 years ago - ie 17 May 1999. At that time providing ones computing power to the scientists from big American research center was for a common user virtual adventure. Research conducted on shared computers involved (and still do) rather "popular" subject, searching in the radio waves, signals that may come from foreign civilization. The project has gained popularity and in this respect a comparison to todays "Facebook " can be quite accurate. One should remember though that this are completely different systems and SETI@Home began operations in 1999, when Internet in Poland was infancy. However, SETI@home and BOINC turned out to be a great initiative, which has already nearly two decades and unites people around the distributed computing.

With this report we are going to make a quick and brief overview of the open-source licenses. Starting with the base ideas of the licensing we'll come to the vastest spread and most popular licenses used in the open-source software. Also one of the most important points of the report I would consider the differentiation of the permissive and copyleft licenses. Краткий обзор базовых лицензий СПО Irina Shubina

Copyright treats scientific publication equal to regular work of art, ignoring its specific nature, that gives some signs of natural monopolies to scientific publishing houses. This severely complicates exchange of scientific info and, so, slows down worldwide research. Present issues of access to publications together with some present and theoretical methods of their solution are discussed. Кандалы прогресса: авторское право и научные публикации Антон Літвіненка

For a long time OpenBSD did not ship modern KDE versions. But during two last years situation changed. The talk is about what happened behind the scenes to make the working KDE4 platform usable by OpenBSD users. There will be covered such things as tweaking CMake modules, authentication support and so on. Also, there was a success in making KDE 3 and 4 co-exist that involved solving assorted technical problems. The experience gained during process could be useful for porting other software on OpenBSD as well as for porting in general. Как пропатчить KDE4 под OpenBSD Vadim Zhukov

Raspberry Pi Tank is open source project, that implements remote control for a toy tank with WebUI and console via Wi-Fi interface. It includes software tools developed for remote control, such as daemon for controlling tank over GPIO, WebUI for transmitting commands and receiving video and others. Workable prototype is part of presentation. Raspberry Pi Tank Павел Бондарь

The world is not ideal that's why some packages can't built under certain architecture (i.e. grub, wine) or some vendors doesn't produce packages (skype, steam). In future it will allow run ancient packages. For this cases all distributives has multiarch support - installing of packages from more then one architecture in one system.<br /> This article is an overview of multiarch realizations in modern GNU/Linux distributives: OpenSUSE, Fedora, Debian/Ubuntu, Gentoo, ArchLinux and describes differences in package lifecycle.

Today Software-Defined Networking is still a cutting-edge rather than a common production technology. In spite of this, SDN technologies are evolving actively, as well as it's enthusiasts community and engineer's culture. It holds out hope that common usage of SDN in world-wide networks is a matter of the closest future. And you're able to be a part of this! We made a review of current SDN state and most valuable solutions which are available right now to build and manage SDN, it's platforms and technology stacks. Wherein we paid a special attention on Open Source software which enables SDN, so everyone can contribute in the future of networking. SDN сегодня Dmitry Orekhov

Psychology is a purely humanitarian science. Nevertheless, specialists more often prefer solutions of application tasks to be done by PC. Automation of diagnostic processes gives more accuracy when choosing healing approach. Free software offers very useful tools for it for a psychologist or a coach.

Gnuradio is a software framework intended in particular to building software defined radio. New functions and new external devices can be added easily by writing plugins. It also has graphical front end to rapidly create software signal processors. I will demonstrate creating software radio receivers with GNUradio and commodity components. Also I will discuss using gnuradio as a general signal processing tool and writing plugins for gnuradio, using processing of electroencephalogram (EEG) as an example. Обзор GNURadio Юрий Адамов

Experience of using virtual machines instead of screenshots in visual timeline of GUI is reviewed. Availability of materials is considered as far as problems of QEMU-based nested virtualization. A solution is proposed for free distribution of F/LOSS virtualized items with a possibility to automaticaly integrate proprietary ones in case of their presence.

The report focuses on a live syncing utility "clsync" developed by UNIX-tech department of NRNU MEPhI for an LXC-based infrastructure. "clsync" is free and open solution, that appears as replacement of "lsyncd" in fine-tuned systems. A practical experience of applying the utility to setup an LXC HA cluster, a backuping system and a configuration files syncing through an HPC cluster is given. clsync – live sync utility Dmitry Okunev

The paper describes practical experience of creating a biometrical device to evaluate user’s stress level. Signs specific to stress are considered as well as the device prototype and intermediate research results. Free/libre open source software used to evaluate and analyse raw biometric data is covered.
