DeviceHive is an open source framework that we have already mentioned several times in our blog. By using this framework, any device can be connected to the cloud.
Our experts came up with an idea of DeviceHive usage with Raspberry Pi and Arduino. Now, you can connect your Arduino to the Web and simultaneously add some more devices.
For anyone who is interested, instructions are available here:

However, LinkedIn has recently changed their interface which required the script to be updated. The new version of the script can be downloaded from GitHub at the following address:
In the previous part of this article we spoke about International security standards. In this part, we’ll talk about the ones which are adopted in the United Kingdom.
Recently, DataArt released a demo-app for Windows 8. The app represents DataArt as the company, provides contact information, lists office locations, tells about success stories and enumerates areas of industrial and technological expertise.
In summer 2011, a developer preview version of Windows 8 was released, and so was Visual Studio 2011. Shortly after that, we decided to make a demo application along the lines of what has already been done for iOS and Windows Phone 7.
In order to answer the question in the title of this post, we have performed research based on data from different recruiting sites.
The research was performed by looking at job offers published in LinkedIn http://www.linkedin.com and on the following job boards:
After analyzing more than 100 vacancies, we have selected the most common responsibilities, requirements, tools, and personal qualities that are listed in the job offers.
This is the first in the series of articles about security standards.
Security standards describe measures which have to be taken to help with keeping confidential data secure and reduce risk of intrusion. Organizations having sensitive data in possession have to comply with these standards in order to operate. Security standards can be classified as national and international. In this first article we will review major international standards adopted in the USA.
There are many mandatory and optional compliance standards which help to defend sensitive data from malicious persons. Unfortunately, during my research I did not meet any documentation which summarizes information about commonly used standards in a single place. I had to dig through official documents, study a lot of additional articles and gather information bit by bit. Because of this I had an idea to create a document which will be useful for everyone who wants to know the basic information about a standard but doesn’t have enough time for a large-scale research.
I divided all standards into three large categories: international and two national, namely US and UK. Some of those are mandatory, others are optional. In this article we’ll talk about standards which are adopted in the USA.
The United States is a country with a wide range of standards that cover almost all aspects of life. Not only government organizations must be compliant with a huge amount of mandatory certifications and standards but financial organizations, organizations within the energy power spheres, healthcare and much more have their own specific standards which mitigate security risks and often are mandatory for compliance.
We were excited to be present at Oracle’s JavaOne conference in San Francisco in September 2013. Just in time for the conference we also released the cloud portion of DeviceHive in Java, in order to meet the needs of the huge open-source community. We used the new Java EE 7 stack, and the features of the new Java products, like EE 7 platform and Java ME Embedded framework present a lot of opportunities for developers.
Once the mobile device giant and dominant smartphone player, BlackBerry was prepared to be sliced into pieces and sold off. Their spokesperson had reported a quarterly loss of $1billion in September. Sales were under the estimated value due to smartphones powered by the Android mobile platform and Apple iOS dominated the market.
The company was soliciting bids after agreeing last month to a tentative $4.7bn offer from its shareholder, Fairfax, and had until 4th November to consider other proposals. Lenovo tried to bid too, but the Canadian government rejected it. On top of that, BlackBerry announced it cuts 4500 jobs last month, which is about 40% of its workforce. The company blamed “more intense competition” following poor sales of its latest devices, the Z and Q lines, released in January and April.
Let’s imagine a situation that you are joining a project where everyone understands that it has grown quite large and some sort of configuration management and orchestration tool is required. This understanding is followed by a lengthy decision making phase when typical products are brought up and discussed, such as Puppet, CFEngine, Chef. But still, things have to be done here and now and on a dozen of hosts. DataArt has experienced this before and is already aware of some other tools like cluster ssh and Fabric and even Marionette Collective. They all look appealing, but still all have their advantages and disadvantages. So let’s add another tool to the list and play around with it a bit, while discussions around a long-term solution are ongoing.
Scala language is getting more and more attention nowadays from the Java community and a number of people even consider it to be a kind of improved Java. As many Java developers work with web technologies and have to deal with the diverse world of Java web frameworks, it would be interesting to have a glance at what Scala brings to the table.
One of the most popular Scala based frameworks is Lift, which was created by David Pollack in 2007. It is written mostly using Scala programming language and leverages its several features. Lift was inspired by a set of other frameworks, such as Ruby on Rails, Seaside, Wicket and Django, and tries to implement their best features, such as security, fast prototyping and designer-friendly templates. It is now used in some major web applications, and the most widely known of them is Foursquare.
