• DeviceHive Predictive Maintenance Application with SAP

    13 July 2016
    By Gleb Popov, Senior Java Developer at DataArt

    The DeviceHive project development team has explored the possibility of integrating the DeviceHive data platform with SAP Hana DB. DeviceHive allows third party IoT device developers to concentrate on business tasks and the distinctive features of a project by shifting the data and device management to the platform. SAP Hana DB provides analytical tools integrated with data storage.

    This approach can be used as a reference architecture solution based on devices that use Ubuntu Core. In our example, the devices collect data from the sensors and transmit it to the cloud for further analysis.

    The DeviceHive platform allows us to collect data sent by devices in various ways. One of the most convenient ways that is available immediately after server installation is to use the data stream in an Apache Kafka server. The data flow available from Kafka topics contains device notifications. Aggregation and data analysis received from the sensors on the fly makes it possible to create a real-time monitoring system.

    By Constantine Mars, Senior Android Developer at DataArt

    Introduction

    The DeviceHive team has released a new version of their gateway for Android N. DeviceHive Android Gateway for Bluetooth Low Energy devices makes it possible to connect multiple Bluetooth Low Energy devices to DeviceHive IoT clouds through a single Android device. Now it’s possible to connect sensors, buttons, indicators, wearables, and any other BLE devices to prototype solutions even faster.

    All that’s needed is to start the gateway, connect it to the device, and send a command (or subscribe to sensor data notifications).

    Here is a presentation showing common use cases for the DeviceHive Gateway on Android.

    This quick tutorial will help to start prototyping the solutions faster.

    By Charlotte Lamp Davies, VP of Travel and Hospitality, DataArt and Anna Grevtseva, VP Online Travel

    The third Phocuswright Europe Conference was held at the Convention Centre Dublin on the 10-12  of May  2016 and drew the continent’s top players to exchange views on the trends in technology for the European travel market. The theme was “Unsettled yet Undeterred”, reflecting the backdrop of Europe’s bumpy economic recovery and reduced spending on travel.

    The travel industry DNA is changing, with important shifts happening from one year’s Phocuswright to the next.

    Stephen Kaufer, CEO, Tripadvisor, emphasized the company’s shifting focus from a review resource to one that accommodates instant bookings. KAYAK and Google have also introduced direct bookings.

  • Today IoT is expanding it’s borders and creeping into our daily lives. Devices are placed everywhere, various size from tiny things to monstrous automatic machinery. The internal device architecture and design form the constraints on the device behavior. Device protocol, operational cycle, and time are often limited by batteries, the underlying hardware, and existing libraries. The variety of protocols and message types means a typical solution to unite them involves implementing bridge-adapters that are capable of transforming data into a common format.

    Bridges are often seen as a pipe accepting messages and passing them to the next collector or adapter-bridge. The central business logic resides in the middle. Central logic responsible for accepting and handling all the messages. The replies are sent back, routed through the channels back to the device and client. A typical solution will require several type of adapters to be deployed. With an increasing number of bridges, fault tolerance requirements should be kept. At this point, cluster maintenance and monitoring becomes important task.

    What has changed?

    For decades, POS workplaces have been built on standard PCs. Starting with DOS, then moving to other operating systems, COM-ports have been replaced by USB, but the situation hasn’t changed much: industrial PCs are put inside a specially designed computer casing.

  • On-demand Interactive Data Science with DC/OS

    Traffic accidents in the UK, 1979-2004.

    Whether you are a journalist, a researcher or a data geek, in order to start working with large data sets, you have to complete laborious tasks of setting-up an infrastructure, configuring an environment, learning new unfamiliar tools and coding complicated apps – with DC/OS you can start crunching those numbers within minutes.

    Let’s start with a problem of analyzing a set of data and take a road safety data from Great Britain, 1979-2004. While the data set might seem small, some of the analysis might require distributed processing and we should have an environment that allows our processing jobs to scale horizontally. To achieve this, we’ll be running a DC/OS cluster on top of a cluster of virtual machines. We’ll be using AWS EC2 in this scenario, but the same solution can be ported to other public and private clouds.

  • Getting started with packages in DC/OS

    19 April 2016
    By Yuri Gubin, Software Architect, DataArt

    Why would one create a package?

    Once you get familiar with DC/OS, the open source project that was created by Mesosphere you get access to packages certified by Mesosphere. There are several ways to deploy your service into DC/OS: (1) use dcos marathon command in CLI; (2) use Marathon REST API directly; (3) deploy your service as a package. Using package approach makes your solution consistent with the environment and gives other benefits.

    Anyone who has been abroad knows that currency conversion occurs whenever you pay with a credit or debit card. However, many don’t understand why charges are relatively high. To help explain the issue, let me explain how your payments happen overseas.

    As soon as you return from your trip, you can compare receipts in foreign currency with your billing. A quick check will show that you have paid 5% more than you expected for the conversion. How did that happen?
