The aim of this paper is reducing recovery time of a failed component in a distributed storage system, hence, increasing availability of the entire cloud infrastructure. Using proposed data placement method, we showed that recovery time of LRC codes can be reduced by 70%-80% on average, and by 160% for regenerating codes, compared to the classical approaches. Besides, this work presents an efficient algorithm of scaling regenerating codes that allows using these codes in dynamic clusters.…
In our presentation we talk about the topic that is vital for many developers – support and evolution of the code of the project. The presented material is based on our real project experience. We discuss the problems we have faced working with legacy code and how we have resolved them. We say also about technical debt, why it happens, what sequences it causes and how to resolve it. We examine the issue of legacy code support, the corresponding risks, possible strategies of evolution of…
In this lecture we consider how to use numerical control approach in a home workshop. Know how the idea of a creator turns into a product. In conclusion of the session we consider the approach of sending G-code instructions for execution on NC from high-level languages. Students learn how this method allows you to use the familiar tools and technology for many IT professionals to generate and modify control programs.
