In multilayers data storages the storage drivers are grouped into separate layers according to their technical characteristics. The first layer contains high-speed solid-state drivers (SSDs), whereas the other layers can have HDDs or others storage devices (tape, optical devices). The multilayer data storage provides high speed data access and can be formed by using hardware or software solutions. In multilevel software-define storages (SDS), the separate data storage are grouped with respect to levels of their technical characteristics, the type of stored data, and availability requirements for the end user. Multilevels SDS allows for optimization of the data placement in the storage. The main node of SDS is represented by a controller. The SDS controller is a software platform (open source and other) which includes solution tools for management, monitoring and migration of data between layers.

Code review is a crucial part of developing a stable and robust open source project, such as Linux kernel. New comers and surprisingly many active and known contributors have been doing same mistakes, like using non-scalable APIs, over and over. How can we eliminate or avoid them? Looking at the patterns the best practices would be suggested. In addition, relatively new Linux kernel APIs, such as Unified Device Properties, will be discussed. Typical mistakes when submitting a new code to Linux kernel Andy Shevchenko

A widely accepted standard for adding functionality to computer systems is the USB bus. GNU/Linux systems have long been supporting USB hosts, but a less known fact is that they also support USB devices. The traditional way of preparing support for devices includes creating a kernel module, which makes the process significantly more difficult. A new approach is presented, which requires only shell scripting. Make your own USB gadget Andrzej Pietrasiewicz

In the presentation different business models based on the digital commons were summarized. The first point is a consideration who controls a modern pool of resources and which characteristics are critical for the resource management. In the second point we discuss how the digital revolution change price-creation of a digital content. Further we elaborate how to make money and foster development based on Creative Commons principles. The last section describes how businesses can operate based on non-market premises and develop the third way in the content creation, distribution and consumption.

In the modern world, geoinformation technologies are routinely present in the life of both individuals and companies as a whole. These are navigation systems, transport monitoring systems and many-sided programs and applications that use spatial information mapping on a cartographic basis. Modernity as a period is an era of commercial development of GIS (geoinformation systems), expansion of the field of their application through integration with DBMS, the emergence of network applications - all this has opened the way for systems that support corporate and distributed geodatabases. This was the impetus for the development of not only commercial geoinformation systems, but also freely distributed products - QGIS, NextGISWEB, MapServer and others Картографический сервис на OpenSource – доступная картография каждому Дмитрий Степанов

«Hubzilla – introduction, possibilities, Hubzilla community» Hubzilla is a free and open source platform running on a special kind of web server, called a "hub", that can connect to other hubs in a decentralised network called "the grid", providing sophisticated communications, identity, and access control services which work together seamlessly across domains and independent websites. It allows anybody to publicly or privately publish content via "channels". Hubzilla – введение, возможности, Hubzilla-сообщество Gustav Wall

Browser makers spend a lot of effort for making SSL right and make PKI harder then ever, but pay too little attention to alternative methods of estimating the web site security. In this talk I will tell about such alternative methods and a little bit about using risk management for security level estimation. Безопасность в браузерах: альтернативы SSL Алексей Хлебников

USB is the most common external interface in the world. Even machines which, for security reasons, are disconnected from the Internet often offer USB connectivity. This creates a new attacks surface for skilled hackers. USB implementation may be exploited on various levels. To effectively protect against such attack, knowledge about already exploited vulnerabilities is required. This paper is a survey of state-of-the-art USB-related attacks. USB attacks explained Krzysztof Opasiak

Amazon cloud service (AWS) provides several container-based services (EC2 CS, Lambda, CodeBuild). These services are quite special to Amazon and differ a lot from Open Source analogs however based on it. The goal of this report is to review common problems based on real experience and to show solutions author had find out.

2016 is a year when exponential growth of world IPv6 adoption was confirmed. Fifth part of Global IP traffic going over IPv6 now. Per country adoption level of IPv6 is very different (from 0% to almost 50% in Europe region). Belarus is only 0,03%. There are many reasons for that and poor technical knowledge of IPv6 is one of them. In my presentation I will talk about IPv6 protocol basics. I'll have a brief look on IPv6 history and compare it with IPv4. Основы IPv6 Иван Семерник

LibreOffice is a well known open-source productivity suite with long and complex history. Thus nowadays we have rather huge (millions lines of code) and difficult in development and support project. How do we continue moving forward? Which tools and techniques do help us? LibreOffice: как разрабатываются большие проекты? Василий Меленчук

Modern mobile devices such as smartphones and tablets now have powerful processors and sometime large amount of memory inside. So these devices can be suitable for standard server tasks, for example data warehousing and HTTP request handling. However, since the architecture of mobiles is different from standard PCs and servers, it is necessary to recompile open source server software for further usage. This is not very simple process and here is the description of key points and main ways of that. Превращение Android-устройств в мобильные серверы при помощи FOSS Виталий Сороко
