Darktable is an open source application devoted to processing of RAW files. The program can manage collections of RAWs with rating, color labels and custom tags. A rich set of built-in filters, used at processing, store their settings in a form of a history stack, which is saved alongside original RAW, providing original RAW untouched.

Since the past 25 years relationship between open source and enterprise changed dramatically. While in the middle of 1990s open source was considered as a hobby for enthusiasts these days most enterprises build their success using open source products. There are three major trends that changed the shape of open source and enterprise relationship over the time 1. enterprise compatibility - we can see a lot of successful open source products used to leverage the business of enterprise products. Among them we can see NGINX, RedHat, etc... 2. product innovation cycle for enterprise software is still stuck on 3 years while open source products have much more agile approach delivering innovative releases much more frequently 3. platform compatibility is the major differentiator between open source and closed source platforms. Open source software helps users to use their products across multiple platforms while closed source application try to stick user on a single platform. The level of integration and trust between enterprise solutions and open source products grows every year. Future innovations and successful businesses start today with help of open source.

Nowadays programs are too complex for verification and any developer can't guarantee that program is valid in every situation. In this talk I'll try to introduce modern ways for automatic testing C/C++ programs. I will talk about proper compiler settings, static and dynamic analyzers, sanitizers and fuzzing tecniques.

This Engineering Report carries the essence of the problem, the integration between the two worlds and the camps of unqualified skeptics, who are often similar to the racetrack. The transition from a proprietary infrastructure to a free one at this given time will always be complicated by two factors - maintenance and integration.

LAVA is a continuous integration system for deploying operating systems onto physical and virtual hardware for running tests. With LAVA, it is possible to run automated tests across multiple hardware platforms in the real operating system environment. LAVA powers the infrastructure behind Kernel CI project, ensuring the Linux kernel is tested on as much hardware as possible without human intervention. This talk will cover LAVA in general and its benefits in the CI process and how it can fit with on your CI infrastructure, and how we at Collabora use it to test Linux distribution images.

Android is very popular mobile platform and amount of apps, that work with sensitive information, for example banking apps, grows every day. Thus anti-reverse-engineering technologies are now increasingy more important. In this presentation I will tell how to obfuscate sensitive data in the Android byte code by moving it to encrypted files that will be decrypted by native code, and how to automate this process. I will use strings as examples of data, but the described technique can be applied to other types of data as well. Продвинутая обфускация констант в Android-приложениях Алексей Хлебников

Free software licenses may be seen as software themselves: they are set of rules and algorithms of how to use software. As any software licenses are not perfect and have vulnerabilities which are exploited to limit our freedom. This talk is about how it happens and what mitigations are available.

In this report, I would like to share the experience of using the DevOps philosophy in our company for one of the projects in the financial sphere. Emphasis will be placed on the work of the quality assurance department, because exactly because of the large number of questions there and the increased quality requirements, the philosophy of DevOps was applied there in the first place.

Everyone wants to build their next application “in the cloud”, but it is easier said than done. Eclipse Che is a scalable, web-based IDE which provides on-demand workspaces that include both runtimes and tools for development in the cloud. It is powered by a RESTful workspace server (with OpenShift or Kubernetes as underlying infrastructure), plug-ins for languages, frameworks and tools. Eclipse Che can do some tricks which desktop IDEs will not be able to accomplish.<br /> In this session, it will be demonstrated how to easily install Eclipse Che on Kubernetes or OpenShift to provide a collaborative developer environment to your team. You will also find out that anyone, anytime can contribute to a project without installing software, spin up a workpace in one-click with all the required dependencies in a browser and that "but it works on my machine!” problem does not really exist in the containers world.
