IN FOCCUS: MACHINE LEARNING
Practical Aspects of Machine Learning
Currently, lots of hopes are being put onto machine learning, but the success of the technology will be determined not only by an adequate algorithm selection, but also by taking the right steps at the planning, development, and implementation stages.

Machine Learning for Natural Language Understanding
Natural language processing technology has made great progress thanks in no small part to machine learning, which is used for text understanding among other things.

Machine Learning for Query Planning
The growing data volumes increasingly require advances in database query performance. An optimization of a query execution plan using machine learning techniques yields many-fold response time improvements.

Machine Learning for a Big Data
Theoretical foundations of machine learning have emerged almost simultaneously with the first computers. Still, when using machine learning techniques in practice, the specific system architecture must always be accounted for. Processing big data with Hadoop requires tools for adapting machine learning algorithms to the platform, which can be done, for example, using elements of the IBM BigInsigths stack.

Assessing Student Competencies Through Social Network Analysis
The third generation of Russia’s National Higher Education Standards define learning tasks in terms of students’ competencies, which necessitates an evaluation framework. This is where machine learning technology comes to help enabling to assess students’ competencies by analyzing their behavior in social networks.

The TOP500 List and Progress in High Performance Computing
For more than two decades, the TOP500 list has enjoyed incredible success as a metric for supercomputing performance and as a source of data for identifying technological trends. The project’s editors reflect on its usefulness and limitations for guiding large-scale scientific computing into the exascale era.

INTERNET OF THINGS
Reference Architectures for the Internet of Things
The Internet of Things (IoT) is about innovative functionality and better productivity by seamlessly connecting devices. But a major threat is the lack of architecture standards for the industrial Internet and connectivity in the IoT. The article gives a review of recent IoT architecture evolution and what it means for industry projects.

Internet of Things for enthusiasts: weather station with visualization
Internet of Things develops today thanks not only to companies offering solutions specifically designed for the Internet of things, but also enthusiasts who extremely need new tools to work with interactive with each other «smart» things.

DBMS Cost-Based Optimizers: Back Story and State of the Art
Query optimizers for relational databases have come a long evolutionary way to grow into complicated algorithms for assessing the costs of various options. However, the new generation databases pay almost zero attention to a query cost. What is it, a step back or two steps ahead? Do we even need new cost optimizers for the big data world at all?

Private Cloud for the Masses
Using OpenStack, one can build a private cloud today. However, the experience of implementing real-world projects has shown that SMB companies prefer turnkey standardized scalable hardware and software solutions packaged with tech support services.

DISPAK: Operating System for USSR Nuclear Project
Nuclear research had been playing a defining role in the political and social and economic development of USSR in the post-WWII era. In particular, Soviet nuclear project has become a powerful driving force for the development of computers, applied math, and software programming. One of the most prominent software products created thanks to the nuclear project was the DISPAK operating system designed for the Soviet-era BECM-6 computer.

On the Way to Open Science
New information systems for scientific collaboration help to tighten scientists’ responsibility for the quality of works they publish, which enables a wider and more open use of the results. One example of such information systems is Socionet.
